From 67b55589ae1c292eeaaa253ccc37bb4f939c3a45 Mon Sep 17 00:00:00 2001 From: AriusII Date: Tue, 22 Sep 2026 23:28:53 +0200 Subject: [PATCH 001/321] Restore consistent coexistence fixture lock files The three LivePlugin.Coexistence fixtures opt out of central package management on purpose, but commit d06fd2e rewrote their version 1 lock files with CentralTransitive entries. Locked-mode restore of the solution then failed with NU1004 on every main, pull request and Dependabot run. Regenerate the files from the CLI with the pinned SDK (dotnet restore --force-evaluate per project); the result matches the blob that last passed CI. --- .../PluginA/packages.lock.json | 120 ++++++++---------- .../PluginB/packages.lock.json | 120 ++++++++---------- .../PluginCollision/packages.lock.json | 120 ++++++++---------- 3 files changed, 168 insertions(+), 192 deletions(-) diff --git a/tests/CheatEngine.Client.LivePlugin.Coexistence/PluginA/packages.lock.json b/tests/CheatEngine.Client.LivePlugin.Coexistence/PluginA/packages.lock.json index 4709618..30eb595 100644 --- a/tests/CheatEngine.Client.LivePlugin.Coexistence/PluginA/packages.lock.json +++ b/tests/CheatEngine.Client.LivePlugin.Coexistence/PluginA/packages.lock.json @@ -23,57 +23,8 @@ "Microsoft.Extensions.Primitives": "10.0.12" } }, -

.NET SDK, analysis level and NuGet audit policy global.json now requires .NET SDK 10.0.401 exactly (rollForward: disable, recommended with lock files because the lock files record SDK-implicit packages such as ILLink and ILCompiler) and names the install command in sdk.errorMessage, available since the .NET 10 SDK (https://learn.microsoft.com/dotnet/core/tools/global-json). AnalysisLevel moves from latest-recommended to the pinned 10.0-recommended so a newer SDK band cannot add CA/IDE errors; with SDK 10.0.401 both resolve to the same analysislevel_10_recommended.globalconfig and /warn:10, so no diagnostic changes. A new "Supply chain" property group states the NuGet audit policy (https://learn.microsoft.com/nuget/concepts/auditing-packages): audit all packages from the low level; NU1903/NU1904 (high, critical) fail every build through TreatWarningsAsErrors; NU1900/NU1901/NU1902/NU1905 stay visible warnings in ordinary builds so a newly published low or moderate advisory cannot turn every required check red without a commit; a dedicated run with -p:AuditPipeline=true turns every audit code into an error. Directory.Build.targets gains the repository guards CHEATENGINECLIENT9030 (AnalysisLevel differs from the pin), 9031 (audit disabled, mode not all, level not low, or NU1903/NU1904 in NoWarn/WarningsNotAsErrors, matched as whole codes) and 9032 (no lock file outside the documented Coexistence SDK override, or CPM off outside the Coexistence fixtures). RestoreLockedMode is deliberately not set in MSBuild: it would break every --force-evaluate restore (NU1005); locked mode is enforced at the CI entry points. ToolchainPinTests freeze the pins; ids 9033-9039 stay reserved. --- Directory.Build.props | 19 +- Directory.Build.targets | 37 ++++ global.json | 5 +- .../README.md | 5 + .../Toolchain/ToolchainPinTests.cs | 175 ++++++++++++++++++ 5 files changed, 238 insertions(+), 3 deletions(-) create mode 100644 tests/CheatEngine.Client.Repository.Tests/Toolchain/ToolchainPinTests.cs diff --git a/Directory.Build.props b/Directory.Build.props index 769878f..1ccda9f 100644 --- a/Directory.Build.props +++ b/Directory.Build.props @@ -13,13 +13,30 @@ enable enable true - latest-recommended + + <_CheatEngineClientPinnedAnalysisLevel>10.0-recommended + $(_CheatEngineClientPinnedAnalysisLevel) true true true true + + + true + all + low + <_CheatEngineClientNuGetAuditCodes>NU1900;NU1901;NU1902;NU1903;NU1904;NU1905 + + $(WarningsNotAsErrors);NU1900;NU1901;NU1902;NU1905 + + $(WarningsAsErrors);$(_CheatEngineClientNuGetAuditCodes) + + 0.1.0 CheatEngineNet diff --git a/Directory.Build.targets b/Directory.Build.targets index 5c1ef69..e3d1db3 100644 --- a/Directory.Build.targets +++ b/Directory.Build.targets @@ -70,4 +70,41 @@ Code="CHEATENGINECLIENT9016" Text="SDK-facing published packages must declare CheatEngine.SDK as [1.0.0, 2.0.0)."/> + + + + + + <_CheatEngineClientNoWarnCodes>;$([System.Text.RegularExpressions.Regex]::Replace('$(NoWarn)', '[\s,;]+', ';').ToUpperInvariant()); + <_CheatEngineClientWarningsNotAsErrorsCodes>;$([System.Text.RegularExpressions.Regex]::Replace('$(WarningsNotAsErrors)', '[\s,;]+', ';').ToUpperInvariant()); + <_CheatEngineClientDowngradesBlockingAudit>false + <_CheatEngineClientDowngradesBlockingAudit Condition="$(_CheatEngineClientNoWarnCodes.Contains(';NU1903;')) or $(_CheatEngineClientNoWarnCodes.Contains(';NU1904;')) or $(_CheatEngineClientWarningsNotAsErrorsCodes.Contains(';NU1903;')) or $(_CheatEngineClientWarningsNotAsErrorsCodes.Contains(';NU1904;'))">true + + <_CheatEngineClientIsCoexistenceFixture>$(_CheatEngineClientFolder.StartsWith('tests/CheatEngine.Client.LivePlugin.Coexistence/', System.StringComparison.OrdinalIgnoreCase)) + + <_CheatEngineClientLockFileOverride>false + <_CheatEngineClientLockFileOverride Condition="'$(_CheatEngineClientIsCoexistenceFixture)' == 'true' and '$(CoexistenceSdkPackageVersion)' != '' and '$(CoexistenceSdkPackageVersion)' != '1.0.0'">true + + + + + + + + diff --git a/global.json b/global.json index 9773a5f..6a239c0 100644 --- a/global.json +++ b/global.json @@ -1,8 +1,9 @@ { "sdk": { "version": "10.0.401", - "rollForward": "latestFeature", - "allowPrerelease": false + "rollForward": "disable", + "allowPrerelease": false, + "errorMessage": "CheatEngine.Client builds only with .NET SDK 10.0.401 exactly (global.json rollForward: disable, NuGet lock files).

It refuses to run off Windows (Native AOT lock sections record host-RID ILCompiler packages), with an SDK other than the global.json one, or with CoexistenceSdkPackageVersion set in the environment (MSBuild reads it as a property and any value other than 1.0.0 turns lock files off for the fixtures). Projects are enumerated from git, never hard-coded; only the template content project is excluded, as in SolutionInventoryTests. The sequence keeps the Coexistence fixtures safe: evaluation must find exactly the three fixtures outside Central Package Management; they are restored first, one by one, with --force-evaluate and must keep version 1 lock files without CentralTransitive entries; every other project follows one by one; the solution is then restored with --locked-mode only (never together with --force-evaluate, NU1005). NuGet writes no final newline, and a plain solution restore strips the newline eight lock files carry, so the script restores the final-newline state committed in HEAD and writes back the original bytes of an unchanged graph. Structural checks then require a lock per project, version 1 or 2 matching the CPM mode, one CheatEngine.SDK identity across the graph, no CheatEngine.Client package from a feed, and the win-x64 ILCompiler runtime pack of every PublishAot project. -Verify, used by the upcoming CI job, fails naming every lock file that differs from git or is untracked. Verified: regeneration of the committed state is a zero diff; a CPM version bump makes --locked-mode fail with NU1004; a hand-edited resolved version passes --locked-mode (NuGet validates requested ranges, not resolved versions) and silently drops the package, which -Verify reports by file name.

Those options belong to the Microsoft.Testing.Platform GitHubActionsReport, HangDump and CrashDump extensions, and a module that lacks the extension owning an option fails with exit code 5 (https://learn.microsoft.com/dotnet/core/tools/dotnet-test-mtp), so eng/Tests.props references all three for every *.Tests project. The versions (2.4.1) were already pinned in Directory.Packages.props. The eight test-module lock files change and are regenerated by the integrator with ./eng/Update-LockFiles.ps1. eng/ci/Test-TestModuleInventory.ps1 proves that nothing vanished from a green run: the set of tests/**/*.Tests.csproj projects tracked by git must equal the {asm}_{tfm}_{arch}.trx reports at the top of the results directory (TrxReport 2.3+ naming; consolidated reports under merged/ are ignored), every module must execute tests and skip none, and the Debug leg must produce one coverage report per module. It prints per-module passed/failed/skipped counts to the job summary. eng/ci/Test-PackageSet.ps1 asserts that the Release pack produced exactly the seven lockstep Client packages and six symbol packages (Templates has none), identities read from each .nuspec, one version, exact file names for a release version, and nothing else; it summarises each file's SHA-256 and embedded SBOM and exports package-source for the package-consumption tests. -RequireSbom is ready for when the packages embed their SBOM. Verified locally: the Debug run with the CI options passes 678 tests in 8 modules, 0 skipped; the inventory reports 8 of 8; the Release pack yields 7 nupkg and 6 snupkg and the package-set check passes, while a wrong release version and -RequireSbom fail with named findings. --- CheatEngine.Client.slnx | 2 + eng/Tests.props | 6 + eng/ci/Test-PackageSet.ps1 | 193 ++++++++++++++++++++++++++++ eng/ci/Test-TestModuleInventory.ps1 | 148 +++++++++++++++++++++ 4 files changed, 349 insertions(+) create mode 100644 eng/ci/Test-PackageSet.ps1 create mode 100644 eng/ci/Test-TestModuleInventory.ps1 diff --git a/CheatEngine.Client.slnx b/CheatEngine.Client.slnx index 47ca6b6..f7b8b4f 100644 --- a/CheatEngine.Client.slnx +++ b/CheatEngine.Client.slnx @@ -14,6 +14,8 @@ + + diff --git a/eng/Tests.props b/eng/Tests.props index b66e29e..c322e31 100644 --- a/eng/Tests.props +++ b/eng/Tests.props @@ -16,6 +16,12 @@ + + + + diff --git a/eng/ci/Test-PackageSet.ps1 b/eng/ci/Test-PackageSet.ps1 new file mode 100644 index 0000000..4caad2c --- /dev/null +++ b/eng/ci/Test-PackageSet.ps1 @@ -0,0 +1,193 @@ +#Requires -Version 7.2 +<# +.SYNOPSIS + Asserts that the Release pack produced exactly the Client package set, and exports it for the package-consumption + tests. + +.DESCRIPTION + The Release leg packs before it tests, and the package-consumption smoke tests install exactly these files + (CHEATENGINE_CLIENT_PACKAGE_SOURCE), so the packages CI tests are the packages it publishes.

Shipping assemblies are the solution projects under src/, libs/ and source-generators/; generated sources (*.g.cs, obj/) are excluded, and the collector already skips [GeneratedCode] members and test assemblies. The job summary shows every value and a suggested baseline floored to 0.1; CI never writes the file. The ratchet is line-only on purpose. The XML format the Sonar importer needs records basic blocks, not branches, so a branch rate converted from it is always 1.0, and dotnet-coverage 18.11.2 keeps only line data for a module that several reports contain, so block coverage cannot be unioned either. The CheatEngine.Client package facade compiles no source and is reported as not measurable instead of being skipped silently; an assembly with source that is missing from the report fails. Floors seeded from a local Debug run with the CI options (678 tests): Abstractions 88.5, Core 68.1, Extensions.DependencyInjection 64.4, Fluent 88.3, Hosting 93.3, SourceGenerators.Lua 90.9. Raising one floor above its value fails with the assembly, metric, floor and actual value.

A failing entry throws with the entry name and the fix (./eng/Update-LockFiles.ps1). The input travels through env, never through an expression inside run. The 'cache' input exists for the scheduled health workflow only and defaults to false: every job of ci.yml, sonar.yml and the release path must not restore a NuGet cache another run could have populated. Locked mode lives here and in the Sonar restore rather than in MSBuild (RestoreLockedMode would break every --force-evaluate restore with NU1005).

Debug adds coverage and excludes the package-consumption tests by trait (--filter-not-trait Category=PackageConsumption), never Skip; Release hands them the packed directory in CHEATENGINE_CLIENT_PACKAGE_SOURCE, set only in that leg because the tests reject a set-but-empty value. The module inventory runs on both legs and the coverage ratchet on Debug. --warnaserror is dropped: it would also promote the replayed NU1901/NU1902 audit warnings and override the audit policy, while TreatWarningsAsErrors keeps compiler and analyzer strictness. - aot publishes and runs the Native AOT probe (the RID comes from the project); binlogs are uploaded on failure only, never the publish folder. - lint runs on every event on ubuntu: actionlint 1.7.12 (checksum-verified), zizmor 1.30.1 offline without advanced security, and the pinned PSScriptAnalyzer; format verifies whitespace without a restore; dependency-review always runs and reviews pull requests with actions/dependency-review-action v5.0.0 (config file, no PR comment, no extra permission); lock-files runs ./eng/Update-LockFiles.ps1 -Verify. - sonar runs when SONAR_EXPECTED holds (inputs.sonar, not merge_group, not Dependabot, not a fork) and waits for the quality gate outside push events. sonar.yml restores in locked mode from a nuget.org-only config before scanner begin, analyses Debug with the coverage artifact, extends the exclusions to docs and the coverage exclusions to tests, eng and docs, uses current action pins and no longer writes GITHUB_ENV. ci_based_analysis stays until the maintainer confirms Automatic Analysis is off. - gate (always(), permissions {}) requires success from every job, and for sonar success when SONAR_EXPECTED is true, skipped otherwise, with a Job/Result/Required/Reason summary. Simulated: all success passes; sonar skipped while expected, sonar run while not expected, a skipped dependency review and a failed build-test all fail. Artifacts use the reserved names only (nuget-packages, build-info, coverage, coverage-report, test-results-*, test-dumps-*, binlogs-*); test-results, sonar-coverage and native-aot-probe are retired. main-ci.yml loses the merge_group trigger and its concurrency group (every main commit keeps its run); both callers pass sonar: true and no repository variable. .github/zizmor.yml justifies the remaining findings: the constant GITHUB_ENV write of the composite action, self-repository (actionlint 1.7.12 rejects '$/'), and a temporary dependabot-cooldown ignore. actionlint and zizmor are clean. --- .github/dependency-review-config.yml | 44 +++ .github/workflows/ci.yml | 521 ++++++++++++++++---------- .github/workflows/main-ci.yml | 15 +- .github/workflows/pull-request-ci.yml | 16 +- .github/workflows/sonar.yml | 205 +++++----- .github/zizmor.yml | 22 ++ 6 files changed, 521 insertions(+), 302 deletions(-) create mode 100644 .github/dependency-review-config.yml create mode 100644 .github/zizmor.yml diff --git a/.github/dependency-review-config.yml b/.github/dependency-review-config.yml new file mode 100644 index 0000000..4363bbe --- /dev/null +++ b/.github/dependency-review-config.yml @@ -0,0 +1,44 @@ +# Configuration of actions/dependency-review-action (ci.yml, job "Dependency review", pull requests only).

WorkflowContractTests (Repository.Tests, YamlDotNet from central package management) assert the contract shared with CheatEngine.SDK over every workflow that exists, so workflows added later are held to it too: - the required check: pull-request-ci.yml, main-ci.yml and, once present, release.yml call ci.yml through job 'ci' named 'CI'; ci.yml keeps exactly the frozen job ids and names (the retired validate and lint-workflows cannot return); the Gate runs always() with permissions {}, reads toJSON(needs) and needs every other job minus an advisory allowlist that is empty in the Client; only sonar and gate have job-level conditions; the sonar condition equals the Gate's SONAR_EXPECTED after whitespace normalisation; - triggers: no pull_request_target or merge_group, no path filters on pull-request-ci.yml or pr-policy.yml, no concurrency on main-ci.yml, cancellation by pull request number on pull-request-ci.yml; - build-test: Build, then Pack (Release, --no-build, package-set check), then one --solution test run whose Debug leg excludes Category=PackageConsumption by trait with --fail-skips on and whose Release leg sets CHEATENGINE_CLIENT_PACKAGE_SOURCE from the Pack output inside the script only; the hang-dump timeout stays at most half of the job timeout; inventory, coverage ratchet and build-info run; no -warnaserror anywhere; the benchmarks are built by the solution and listed; - jobs: the AOT probe publishes without --runtime and runs; lint runs actionlint (checksum), zizmor (exact version, offline, no advanced security) and the pinned script analysis on every event; format verifies whitespace without restore; dependency review always runs and reviews pull requests only; lock-files runs the -Verify script on Windows; every zizmor exception carries a justification and its file:line still points at the justified construct; - hygiene: pinned runner labels and a timeout on every job (reusable-workflow callers excepted), read-only top-level permissions, pwsh defaults in the four pipeline workflows, every remote action pinned to a full SHA with a vX.Y.Z comment and one pin per action matching the canonical table, persist-credentials: false on every checkout, full history wherever a version is computed (or an explicit MinVerSkip), locked restores through the composite action in every job that runs dotnet, no NuGet cache on ci.yml, sonar.yml, codeql.yml or release.yml except Sonar's analyzer cache saved from main only, reserved artifact names only, binary logs on failure only and never from sonar.yml or release.yml, no repository variables, no reference to eng/qualification. TestProfileTests ties the options of the CI test command to the Microsoft.Testing.Platform extensions eng/Tests.props gives every test module. Each of the four scratch mutations of the contract (a job dropped from gate.needs, runs-on windows-latest, a paths filter on pull-request-ci.yml, one character of the sonar condition) fails a named test with an actionable message. --- ...CheatEngine.Client.Repository.Tests.csproj | 5 + .../README.md | 10 + .../Toolchain/TestProfileTests.cs | 61 ++ .../Workflows/WorkflowContractTests.cs | 992 ++++++++++++++++++ .../Workflows/WorkflowFile.cs | 350 ++++++ 5 files changed, 1418 insertions(+) create mode 100644 tests/CheatEngine.Client.Repository.Tests/Toolchain/TestProfileTests.cs create mode 100644 tests/CheatEngine.Client.Repository.Tests/Workflows/WorkflowContractTests.cs create mode 100644 tests/CheatEngine.Client.Repository.Tests/Workflows/WorkflowFile.cs diff --git a/tests/CheatEngine.Client.Repository.Tests/CheatEngine.Client.Repository.Tests.csproj b/tests/CheatEngine.Client.Repository.Tests/CheatEngine.Client.Repository.Tests.csproj index 50a79bf..5423f3a 100644 --- a/tests/CheatEngine.Client.Repository.Tests/CheatEngine.Client.Repository.Tests.csproj +++ b/tests/CheatEngine.Client.Repository.Tests/CheatEngine.Client.Repository.Tests.csproj @@ -9,4 +9,9 @@ + + + + + diff --git a/tests/CheatEngine.Client.Repository.Tests/README.md b/tests/CheatEngine.Client.Repository.Tests/README.md index da35ba7..e44c444 100644 --- a/tests/CheatEngine.Client.Repository.Tests/README.md +++ b/tests/CheatEngine.Client.Repository.Tests/README.md @@ -31,6 +31,16 @@ project never builds, packs, restores or starts a process, so it runs in seconds tolerance, and the `dotnet-coverage` merge tool pinned to the collector's version in `.config/dotnet-tools.json`. - `Workflows/BuildInfoSchemaTests` keep `eng/ci/build-info.v0.schema.json`, the contract fields of `build-info.json` and its writer `eng/ci/New-BuildInfo.ps1` in step, and every object of the schema closed to unknown properties. +- `Workflows/WorkflowContractTests` freeze the CI contract shared with CheatEngine.SDK, over every workflow that + exists: callers reach `ci.yml` through job `ci` named `CI`, so the only required check is `CI / Gate`; the Gate runs + `always()` without permissions and needs every other job; the Sonar condition equals the Gate's `SONAR_EXPECTED`; + no `pull_request_target`, `merge_group` or path filter; pinned runner labels and a timeout on every job; read-only + top-level permissions; every action pinned to a full SHA with its version, one pin per action; no credential left + by checkout; no NuGet cache on a release-reachable path; locked restores through the composite setup action; the + Release leg packs before it tests and hands the packages to the consumption tests, which Debug excludes by trait; + reserved artifact names and binary logs on failure only. `Workflows/WorkflowFile` loads the YAML with YamlDotNet. +- `Toolchain/TestProfileTests` prove that every `*.Tests` project references the Microsoft.Testing.Platform extension + of every option the CI test command passes (a missing one fails the module with exit code 5). ## Run diff --git a/tests/CheatEngine.Client.Repository.Tests/Toolchain/TestProfileTests.cs b/tests/CheatEngine.Client.Repository.Tests/Toolchain/TestProfileTests.cs new file mode 100644 index 0000000..b1fee0f --- /dev/null +++ b/tests/CheatEngine.Client.Repository.Tests/Toolchain/TestProfileTests.cs @@ -0,0 +1,61 @@ +using CheatEngine.Client.Repository.Tests.Infrastructure; +using CheatEngine.Client.Repository.Tests.Workflows; + +namespace CheatEngine.Client.Repository.Tests.Toolchain; + +/// +/// CI runs every test module in one dotnet test --solution call with a single option set.

Subject: [PATCH 017/321] Add advisory CodeQL, Scorecard and online zizmor workflows None of the three is a required check; they feed the Security tab. CodeQL (PR-CQ-23, CI-CLI-11, CI-BOTH-4) analyses C# from a manual, traced Release build of src/CheatEngine.Client, which compiles every shipped assembly and the Lua source generator, so generated code is analysed (build-mode none would skip it). The build disables incremental builds, build servers and the shared compiler so the compiler runs under the tracer. GitHub Actions workflows are analysed without a build. There is no dependency or TRAP cache on this path (shared-contracts 1.5), and the code-scanning default setup must stay off. Scorecard (PR-CQ-25) keeps to the restrictions the Scorecard API checks when publish_results is true: no env or defaults at any level, only allowlisted uses: steps, id-token: write on the Scorecard job only, one supported Ubuntu label. Publication works from the default branch only. Online zizmor (PR-CQ-21) runs the online audits with the same zizmor version as the blocking offline run of the Gate, uploads SARIF, and is skipped for fork pull requests, whose token cannot upload. The Governance tests read the committed YAML through a small YamlDotNet helper. OnlineZizmorPinsTheSameVersionAsTheGate needs the zizmor step that C-CI adds to ci.yml. --- .github/workflows/codeql.yml | 107 ++++++++++ .github/workflows/scorecard.yml | 53 +++++ .github/workflows/zizmor-online.yml | 47 +++++ .../Governance/CodeQlWorkflowTests.cs | 131 ++++++++++++ .../Governance/GovernanceFile.cs | 198 ++++++++++++++++++ .../Governance/OnlineZizmorWorkflowTests.cs | 61 ++++++ .../Governance/ScorecardWorkflowTests.cs | 90 ++++++++ 7 files changed, 687 insertions(+) create mode 100644 .github/workflows/codeql.yml create mode 100644 .github/workflows/scorecard.yml create mode 100644 .github/workflows/zizmor-online.yml create mode 100644 tests/CheatEngine.Client.Repository.Tests/Governance/CodeQlWorkflowTests.cs create mode 100644 tests/CheatEngine.Client.Repository.Tests/Governance/GovernanceFile.cs create mode 100644 tests/CheatEngine.Client.Repository.Tests/Governance/OnlineZizmorWorkflowTests.cs create mode 100644 tests/CheatEngine.Client.Repository.Tests/Governance/ScorecardWorkflowTests.cs diff --git a/.github/workflows/codeql.yml b/.github/workflows/codeql.yml new file mode 100644 index 0000000..0baebc7 --- /dev/null +++ b/.github/workflows/codeql.yml @@ -0,0 +1,107 @@ +# Advisory CodeQL code scanning.

Security updates are not delayed. - NuGet at / covers every csproj, Directory.Packages.props, the Coexistence fixture props and .config/dotnet-tools.json. It is grouped into minor/patch version updates and security updates. - GitHub Actions covers the workflows and the composite actions under .github/actions/*. - dotnet-sdk updates global.json; .NET majors are ignored. - Ignores: CheatEngine.SDK majors (the Client stays on 1.x, CHEATENGINECLIENT9016), the Roslyn packages that move with the Lua generator floor, and the SDK-implicit ILLink/ILCompiler packages that move only with global.json. - No commit-message prefix: a prefix produces "deps: ..." subjects, which the pull request title policy forbids. Dependabot pull requests are exempt from that policy. The header records the lock-file procedure for Dependabot pull requests.

It runs on every pull request, drafts included, and on title or body edits, so it stays cheap: Ubuntu, no .NET, no path filter. The rules are data in eng/ci/pr-policy.json and the script holds no rule literal: - title: at most 72 text elements, no surrounding whitespace, uppercase first letter, no Conventional-Commit prefix (the contract regex), no trailing period, and an imperative first word (no past tense, gerund, third person or placeholder, with an allowlist for verbs such as Embed or Focus); - CHANGELOG.md must change when a path under libs/, src/, source-generators/ or templates/ changes (lock files excluded), unless the description has on its own line; a marker inside a sentence does not opt out, so the pull request template can mention it; - dependabot[bot] is exempt. eng/ci/Test-PullRequestPolicy.ps1 reads user text only from environment variables, never prints the body, escapes workflow-command data, and diffs base...head with --no-renames so a move out of libs/ still counts. All matching is case-sensitive, like the C# mirror. PullRequestPolicyRules evaluates the same file with the same .NET regex engine and is the executable specification. The tests cover real titles from both repositories, the rejected history subjects, the length limit in text elements, the changelog paths and marker, the Dependabot exemption, the workflow shape, and raw-text checks that keep the script free of rule literals and case-insensitive operators. --- .github/workflows/pr-policy.yml | 42 +++ eng/ci/Test-PullRequestPolicy.ps1 | 243 ++++++++++++++ eng/ci/pr-policy.json | 50 +++ .../Governance/PullRequestPolicyRules.cs | 189 +++++++++++ .../Governance/PullRequestPolicyTests.cs | 303 ++++++++++++++++++ 5 files changed, 827 insertions(+) create mode 100644 .github/workflows/pr-policy.yml create mode 100644 eng/ci/Test-PullRequestPolicy.ps1 create mode 100644 eng/ci/pr-policy.json create mode 100644 tests/CheatEngine.Client.Repository.Tests/Governance/PullRequestPolicyRules.cs create mode 100644 tests/CheatEngine.Client.Repository.Tests/Governance/PullRequestPolicyTests.cs diff --git a/.github/workflows/pr-policy.yml b/.github/workflows/pr-policy.yml new file mode 100644 index 0000000..4057d3d --- /dev/null +++ b/.github/workflows/pr-policy.yml @@ -0,0 +1,42 @@ +# Second required check, context "PR policy" (shared-contracts §1.2, §1.12).

It asks for the release tuple, sets a best-effort acknowledgement target of 7 days (single maintainer), and scopes the policy: the seven CheatEngine.Client* packages, the ceplugin template content and the workflows are in scope; CheatEngine.SDK, Cheat Engine itself and unauthorized use are out of scope. - CODE_OF_CONDUCT.md is the Contributor Covenant 2.1 (CC BY 4.0). Its contact is the private reporting form, not a personal address. - .github/CODEOWNERS is informational: code-owner review stays off while there is one maintainer. Owner: @AriusII. - The issue forms replace blank issues. The compatibility form requires the full release tuple of audit ch.21 l.15: Client and SDK versions, the SDK contentHash from packages.lock.json, the bridge and Lua DLL hashes, the exact Cheat Engine build and hash, the ce.runtimeconfig.json hash and state, the installed runtimes, the load profile, the plugin build settings and the qualification level where the problem was seen (C0-C4). This is the Client's part of the Checkpoint F exit: "an issue of compatibility can be tied to a precise tuple". config.yml links private reporting, the SDK issues and upstream Cheat Engine. The tests check the form schema rules, the required tuple, known labels, CODEOWNERS syntax and exact-case paths, and that no document contains a local path (ADR-12). Forms, CODEOWNERS and the security policy take effect once merged into the default branch. --- .github/CODEOWNERS | 16 ++ .github/ISSUE_TEMPLATE/bug_report.yml | 75 ++++++ .github/ISSUE_TEMPLATE/compatibility.yml | 212 +++++++++++++++ .github/ISSUE_TEMPLATE/config.yml | 11 + .github/ISSUE_TEMPLATE/feature_request.yml | 38 +++ CODE_OF_CONDUCT.md | 108 ++++++++ SECURITY.md | 57 ++++ .../Governance/CommunityHealthTests.cs | 157 +++++++++++ .../Governance/IssueFormTests.cs | 245 ++++++++++++++++++ 9 files changed, 919 insertions(+) create mode 100644 .github/CODEOWNERS create mode 100644 .github/ISSUE_TEMPLATE/bug_report.yml create mode 100644 .github/ISSUE_TEMPLATE/compatibility.yml create mode 100644 .github/ISSUE_TEMPLATE/config.yml create mode 100644 .github/ISSUE_TEMPLATE/feature_request.yml create mode 100644 CODE_OF_CONDUCT.md create mode 100644 SECURITY.md create mode 100644 tests/CheatEngine.Client.Repository.Tests/Governance/CommunityHealthTests.cs create mode 100644 tests/CheatEngine.Client.Repository.Tests/Governance/IssueFormTests.cs diff --git a/.github/CODEOWNERS b/.github/CODEOWNERS new file mode 100644 index 0000000..77089b0 --- /dev/null +++ b/.github/CODEOWNERS @@ -0,0 +1,16 @@ +# Informational only.

Then dotnet package list --vulnerable and --deprecated, which cannot be combined. Any vulnerable package fails the job; deprecated packages are warnings. https://learn.microsoft.com/nuget/concepts/auditing-packages#running-nuget-audit-in-ci - Weekly newest-SDK canary: reads latest-sdk from the 10.0 release metadata and rewrites only sdk.version in place, so rollForward, errorMessage and the MTP test runner section stay byte-identical. Then the composite action installs that SDK, eng/Update-LockFiles.ps1 regenerates the locks, and the solution is built, packed and tested in Release. The global.json and lock-file diff is uploaded as sdk-canary-patch, to apply to the Dependabot dotnet-sdk pull request. - Daily repeat run of the threading-sensitive test modules (Core and Hosting). Every iteration runs, then the job fails and lists every test that failed at least once. There is no retry extension: a flaky test is fixed or deleted. - A failed scheduled run opens, or comments on, one "Scheduled health failed" issue. Only that job has issues: write. Schedules and dispatch run from the default branch only. Before merge, the 'dry-run' label on a pull request runs every job once. The SDK's "rebuild the last release bridge" check has no Client equivalent: the Client ships no native code. --- .github/workflows/scheduled-health.yml | 153 +++++++ eng/ci/Invoke-ScheduledHealth.ps1 | 400 ++++++++++++++++++ .../ScheduledHealthWorkflowTests.cs | 134 ++++++ 3 files changed, 687 insertions(+) create mode 100644 .github/workflows/scheduled-health.yml create mode 100644 eng/ci/Invoke-ScheduledHealth.ps1 create mode 100644 tests/CheatEngine.Client.Repository.Tests/Governance/ScheduledHealthWorkflowTests.cs diff --git a/.github/workflows/scheduled-health.yml b/.github/workflows/scheduled-health.yml new file mode 100644 index 0000000..2713624 --- /dev/null +++ b/.github/workflows/scheduled-health.yml @@ -0,0 +1,153 @@ +# Advisory scheduled health, never part of CI / Gate (eng/ci/Invoke-ScheduledHealth.ps1 does the work). +# - Weekly: strict NuGet audit over a fresh package folder, newest .NET 10 SDK canary (lock-file patch artifact) and +# the repeat run. +# - Daily: repeat run of the threading-sensitive test modules (flaky-test policy: no automatic retries anywhere). +# - A failed scheduled run opens, or comments on, one "Scheduled health failed" issue. +# Schedules and workflow_dispatch run from the default branch only, and GitHub disables schedules after 60 days without +# repository activity.

Dependency review is blind to NuGet without a submitted snapshot. The job is split in two: - detect (read-only token, Windows because the AOT probe's lock file has win-x64 sections) runs eng/ci/New-DependencySnapshot.ps1. The script downloads Component Detection v8.0.1, checks its SHA-256 before running it, re-runs the locked restore with a binary log so test-project packages are classified as development dependencies, and scans with the NuGet detectors. It then writes the snapshot body with one manifest per project (repository-relative paths only), direct or indirect relationships and the exact dependency edges. A sanity gate requires at least 20 packages and the CheatEngine.SDK version resolved in libs/CheatEngine.Client.Core/packages.lock.json. The binary log never leaves the runner. - submit is the only job with contents: write. It runs no third-party code: download-artifact, then one gh api POST. The official submission action is not used. It downloads the latest Component Detection release at run time and executes it next to a contents: write token. Pushes to main give dependency review its base snapshot. Same-repository pull requests, Dependabot's included, submit a snapshot of the pull request head commit, which gives dependency review a head graph.

A repository administrator runs it from a workstation, in Wave 5, after main is green; the script refuses to run in CI. Desired state: - ruleset "Protect main" (matched by name): no deletion or force push, squash merges only, no bypass actor, required checks "CI / Gate" and "PR policy" from the GitHub Actions app (integration 15368); - ruleset "Protect release tags" on refs/tags/v*: no deletion, force push or update, and no creation rule, so the maintainer can still tag; - squash merges titled by the policed pull request title; - environment nuget: a required reviewer (default AriusII), no admin bypass, v*.*.* tags only; - actions pinned by full SHA, a read-only default token; - verified only: private vulnerability reporting, Dependabot alerts and security updates, secret scanning and push protection on, code scanning default setup off. The default mode issues GET requests only and exits 1 on drift. -PlanOnly prints the payloads offline. -Apply writes the drifting areas through Invoke-GitHubMutation, the only non-GET path, then re-reads everything. -SkipRequiredChecks and -EnableImmutableReleases handle the two sequencing constraints. A read-only run on 2026-09-23 reported the expected drift: merge methods, squash title, SHA pinning, required checks, the tag ruleset and the nuget reviewer.

EveryDotnetJobUsesTheCompositeSetupAction failed on the job. The global.json rewrite now lives in eng/ci/Select-NewestDotNetSdk.ps1, which never runs the .NET CLI (no SDK is installed yet when it runs), and C-CI's rule keeps guarding that property instead of exempting the step. Invoke-ScheduledHealth.ps1 keeps the Audit, Canary and Repeat modes. - The rewrite changed only sdk.version, so sdk.errorMessage still named the pinned SDK. The canary's Release tests include ToolchainPinTests.GlobalJsonErrorMessageNamesThePinnedSdkVersion, so every week with a newer 10.0 SDK the canary would fail regardless of compatibility and the sdk-canary-patch artifact would leave CI red. Every whole occurrence of the pinned version inside the errorMessage string now moves too; the parse-and-compare guard allows exactly these two changes, and rollForward, allowPrerelease and test.runner stay byte-identical. -SdkVersion allows offline tries on a copy. GlobalJsonSdkRewrite mirrors the rewrite in C# with the same patterns, which a test finds verbatim in the script, and runs it on the committed global.json. The Audit mode now puts NUGET_PACKAGES under RUNNER_TEMP on a runner. The Dependabot header explains that the patch applies on top of main's global.json. The workflow's concurrency group now includes the label name, so a later label event of the same pull request cannot replace a pending 'dry-run' run.

Date: Wed, 23 Sep 2026 02:39:49 +0200 Subject: [PATCH 027/321] Refuse dependency snapshots that name another commit, ref or correlator The detect job runs pull request code (a locked restore evaluates the build files of updated packages, for example on a Dependabot pull request), so the dependency-snapshot artifact the submit job downloads is untrusted. Posted verbatim with contents: write, a tampered snapshot could choose any sha, ref or correlator, for example overwrite the refs/heads/main snapshot from a pull request run. The submit step now parses the artifact, accepts only the top-level properties the snapshot script writes, requires version 0 and object-valued detector, job and manifests, and requires sha, ref and job.correlator to equal this run's values from the trusted github context (the same expressions the detect step passes to the script). A mismatch fails before anything is posted. Only pwsh built-ins are used; no third-party code runs next to the token. The concurrency group now cancels in-progress runs only for pull requests, as codeql.yml does: a quick second push to main no longer drops the first commit's base snapshot.

Audit ADR-10 and A21-01 require one reviewed source, a guard, a bump procedure and a reviewed identity of the package (A21-02 for the hash vocabulary). - eng/CheatEngineSdk.props (imported by Directory.Packages.props, so also by the CPM-off Coexistence fixtures) assigns CheatEngineSdkVersion 1.0.0, CheatEngineSdkUpperBound 2.0.0, the range [1.0.0,2.0.0) and the supported major, unconditionally: only a -p: global property can override them, never the environment. - The central PackageVersion, the three VersionOverride ranges and the Coexistence default derive from it; evaluated values are unchanged, so no lock file changes. - CHEATENGINECLIENT9016 now runs before CollectPackageReferences in every project (restore and build fail before NU1102) and refuses a prerelease, another major or an inconsistent range; the pack-time range check prints the derived range. CheatEngineSdkCanary=true turns the build errors into messages for the SDK-side client-canary job, and CheatEngineClientRefuseUnsupportedSdkPack refuses to pack. - CHEATENGINECLIENT9017 refuses a CheatEngine.SDK version written outside the pin (VersionOverride other than the range in the libs, any version elsewhere in CPM projects, a stray PackageVersion). - eng/sdk/consumed-sdk.json (cheatengine-consumed-sdk/v0, schema next to it) records the reviewed identity of 1.0.0 with the field names of the Client tuple: lock content hash, signed-file SHA-256/SHA-512, attested asset, source commit and tree, bridge hash and fingerprint. Values re-verified against the NuGet cache and nuget.org. - eng/sdk/Update-CheatEngineSdk.ps1 verifies the current pin (no-op under -WhatIf) or moves it: it refuses prereleases, other majors (unless -AllowMajor) and unpublished versions before touching files, checks the repository signature with dotnet nuget verify --all, and never guesses the fields nuget.org cannot provide. - Repository tests pin the single source, prose mentions, lock files, identity and schema; Client BuildGuardTests run the guard targets with overridden global properties. Negative checks run locally: -p:CheatEngineSdkVersion=2.0.0 fails restore and build with 9016; 1.1.0-beta.1 fails with 9016; a hand-set VersionOverride="[1.0.0,2.0.0]" in Core fails with 9017; the script refuses 9.9.9, 1.0.99 and 1.1.0-beta.1 and verifies 1.0.0. https://learn.microsoft.com/nuget/consume-packages/central-package-management#overriding-package-versions https://learn.microsoft.com/dotnet/core/tools/dotnet-nuget-verify --- CheatEngine.Client.slnx | 7 + Directory.Build.targets | 67 +++- Directory.Packages.props | 5 +- docs/README.md | 1 + eng/CheatEngineSdk.props | 35 ++ eng/sdk/README.md | 95 +++++ eng/sdk/Update-CheatEngineSdk.ps1 | 351 ++++++++++++++++++ eng/sdk/consumed-sdk.json | 18 + eng/sdk/consumed-sdk.v0.schema.json | 98 +++++ .../CheatEngine.Client.Abstractions.csproj | 2 +- .../CheatEngine.Client.Core.csproj | 2 +- .../CheatEngine.Client.Hosting.csproj | 2 +- .../CoexistencePlugin.props | 7 +- .../README.md | 7 +- .../Packaging/SdkPin.cs | 59 +++ .../Packaging/SdkPinTests.cs | 309 +++++++++++++++ .../README.md | 9 + .../Release/JsonSchemaSubset.cs | 204 ++++++++++ .../Infrastructure/RepositoryLayout.cs | 35 ++ .../Packaging/BuildGuardTests.cs | 74 ++++ tests/CheatEngine.Client.Tests/README.md | 6 + 21 files changed, 1381 insertions(+), 12 deletions(-) create mode 100644 eng/CheatEngineSdk.props create mode 100644 eng/sdk/README.md create mode 100644 eng/sdk/Update-CheatEngineSdk.ps1 create mode 100644 eng/sdk/consumed-sdk.json create mode 100644 eng/sdk/consumed-sdk.v0.schema.json create mode 100644 tests/CheatEngine.Client.Repository.Tests/Packaging/SdkPin.cs create mode 100644 tests/CheatEngine.Client.Repository.Tests/Packaging/SdkPinTests.cs create mode 100644 tests/CheatEngine.Client.Repository.Tests/Release/JsonSchemaSubset.cs create mode 100644 tests/CheatEngine.Client.Tests/Infrastructure/RepositoryLayout.cs create mode 100644 tests/CheatEngine.Client.Tests/Packaging/BuildGuardTests.cs diff --git a/CheatEngine.Client.slnx b/CheatEngine.Client.slnx index 8d7e532..5f9a74a 100644 --- a/CheatEngine.Client.slnx +++ b/CheatEngine.Client.slnx @@ -15,6 +15,7 @@ + @@ -29,6 +30,12 @@ + + + + + + diff --git a/Directory.Build.targets b/Directory.Build.targets index e3d1db3..44874d6 100644 --- a/Directory.Build.targets +++ b/Directory.Build.targets @@ -42,7 +42,7 @@ <_CheatEngineClientSdkReference Include="@(PackageReference)" Condition="'%(PackageReference.Identity)' == 'CheatEngine.SDK' and '%(PackageReference.DefiningProjectName)' == '$(MSBuildProjectName)'"/> <_CheatEngineClientSdkRangeReference Include="@(_CheatEngineClientSdkReference)" - Condition="'%(_CheatEngineClientSdkReference.VersionOverride)' == '[1.0.0,2.0.0)'"/> + Condition="'%(_CheatEngineClientSdkReference.VersionOverride)' == '$(CheatEngineSdkVersionRange)'"/> <_CheatEngineClientProjectReferences>@(_CheatEngineClientDirectProjectReference->'%(Filename)') @@ -68,7 +68,70 @@ Text="CheatEngine.Client must reference only CheatEngine.Client.Fluent and CheatEngine.Client.Hosting."/> + Text="SDK-facing published packages must declare CheatEngine.SDK as $(CheatEngineSdkVersionRange), the range of eng/CheatEngineSdk.props."/> + + + + + + <_CheatEngineClientSdkPinMajor>$([System.Text.RegularExpressions.Regex]::Match('$(CheatEngineSdkVersion)', '^[0-9]+').Value) + <_CheatEngineClientSdkPinProblem> + <_CheatEngineClientSdkPinProblem Condition="!$([System.Text.RegularExpressions.Regex]::IsMatch('$(CheatEngineSdkVersion)', '^[0-9]+\.[0-9]+\.[0-9]+(-[0-9A-Za-z.-]+)?$'))">is not a NuGet version + <_CheatEngineClientSdkPinProblem Condition="'$(_CheatEngineClientSdkPinProblem)' == '' and $(CheatEngineSdkVersion.Contains('-'))">is a prerelease + <_CheatEngineClientSdkPinProblem Condition="'$(_CheatEngineClientSdkPinProblem)' == '' and '$(_CheatEngineClientSdkPinMajor)' != '$(_CheatEngineClientSupportedSdkMajor)'">has major version $(_CheatEngineClientSdkPinMajor), but this Client supports CheatEngine.SDK $(_CheatEngineClientSupportedSdkMajor).x only + <_CheatEngineClientSdkPinProblem Condition="'$(_CheatEngineClientSdkPinProblem)' == '' and !$(CheatEngineSdkVersionRange.StartsWith('[$(CheatEngineSdkVersion),'))">is not the lower bound of the declared range '$(CheatEngineSdkVersionRange)' + <_CheatEngineClientSdkPinMessage>The consumed CheatEngine.SDK version '$(CheatEngineSdkVersion)' $(_CheatEngineClientSdkPinProblem).

VersionPrefix stays as an evaluation-time placeholder equal to the floor ($(MinVerMinimumMajorMinor).0): NuGet records it for project references in lock files ([0.1.0, )), so the three Coexistence v1 locks stay byte-identical. - Directory.Build.targets: CheatEngineClientAssemblyVersion runs after MinVer and keeps major.minor (0.1.0.0) while the major is 0; MinVer alone would regress it to 0.0.0.0, and a 0.x minor is breaking.

Microsoft.Sbom.Targets 4.1.13 (pre-registered in CPM) generates an SPDX 2.2 document after Pack, writes it to _manifest/spdx_2.2/manifest.spdx.json inside the .nupkg and re-zips it; the .snupkg is untouched. - eng/Shipping.props and eng/Templates.props reference the package (PrivateAssets=all) and set GenerateSBOM=true unconditionally, so a local pack and the CI pack carry the same inventory; supplier CheatEngineNet; namespace base https://github.com/CheatEngineNet/CheatEngine.Client. - CheatEngineClientSbomPackageVersion (after MinVer): the package derives SbomGenerationPackageVersion from the evaluation-time $(Version), i.e. the 0.1.0 placeholder; it now names the MinVer version the package carries (checked: 0.1.0-alpha.0.34). - CheatEngineClientPrepareSbomComponents: the default component path (the project folder) holds no restore output under the artifacts layout, so no package was listed; the obj folder also exposed stale nuspec files of earlier packs as components. The SBOM now scans a folder holding only the project's project.assets.json and lists the resolved NuGet graph: runtime dependencies (CheatEngine.SDK 1.0.0, Microsoft.Extensions.*) and build-only tools (MinVer, analyzers, Microsoft.Sbom.Targets, ILLink tasks) alike. No local path appears in the document. - CHEATENGINECLIENT9021 refuses a pack with GenerateSBOM other than true or without the package reference (checked: -p:GenerateSBOM=false fails). The nupkg is no longer byte-reproducible (the SPDX namespace and creation time change on every pack); reproducibility is promised at DLL level.

With MinVer the co-packed version is 0.1.0-alpha.0.N, so an instantiated template would restore an unrelated 0.1.0 (a stale one exists in developer caches), and nothing validated the template before it was packed (CI-CLI-07, CI-MS-11; A04-10). - The repository copy of content/CheatEngine.Plugin/CheatEngine.Plugin.csproj keeps readable defaults (Client = MinVer floor, SDK = pin, Configuration.Json = CPM version) and says to keep CheatEngine.SDK on 1.x; PackageVersioningTests pins those defaults. - _CheatEngineClientStampTemplateProject, listed in TargetsForTfmSpecificContentInPackage (the pack extension point Hosting already uses), runs after MinVer, writes a copy under $(IntermediateOutputPath)template/ with the co-packed PackageVersion, the pinned CheatEngineSdkVersion and the central Configuration.Json version, reads the three values back with XmlPeek (CHEATENGINECLIENT9018) and packs it at content/CheatEngine.Plugin/CheatEngine.Plugin.csproj. An inline task replaces only the Version attributes, because XmlPoke re-serializes the document; the packed file equals the repository file once the versions are replaced (checked). The original is Pack="false", and content bin/ and obj/ folders are excluded. - Template validation: Microsoft.TemplateEngine.Authoring.Tasks 10.0.401 (the package that validates; Microsoft.TemplateEngine.Tasks stops at 7.0.120 and only localizes) with ValidateTemplatesPath set to content/ and LocalizeTemplates=false. It loads in-process with the .NET 10.0.401 MSBuild (open issue O5 resolved) and runs at build, before the no-build pack. It reports MV007-MV009 (missing groupIdentity, generatorVersions, precedence) as messages only, so template.json is unchanged.

PackageSourceResolutionTests carry no category, so both legs run them. - PackagedClientFeedFixture (collection fixture) resolves or packs the feed, reads every archive once, and restores and builds the isolated consumer and the instantiated template once, outside any repository, so the collection stays far inside the hang-dump inactivity window (whole run measured at about one minute locally). Every child dotnet gets one environment: NUGET_PACKAGES and --packages to an isolated folder, an isolated HTTP cache, DOTNET_CLI_HOME/DOTNET_NEW_HOME, the first-run switches, no MSBuild server or node reuse, and no shared compiler server. The NuGet.Config maps CheatEngine.Client and CheatEngine.Client.* to the local feed and CheatEngine.SDK plus * to nuget.org (a packageSourceMapping section may only hold packageSource elements, so it has no clear). The SDK version and identity come from eng/CheatEngineSdk.props and eng/sdk/consumed-sdk.json; CHEATENGINE_SDK_PACKAGE_SOURCE optionally maps the SDK to a folder. - The class carries [Trait("Category", "PackageConsumption")] and [Trait("Qualification", "Q40")]; each fact writes evidence lines (package SHA-256s, bridge SHA-256, content hash) into the TRX. - New facts: package inventory (7 nupkg, 5 snupkg with PDBs), one version, the pinned SDK range with the observed exclude attributes frozen (Abstractions and Hosting "Build,Native,Analyzers, BuildTransitive", Core "Build,Analyzers"), co-packed inter-Client dependencies, the generator as the only analyzer, AssemblyVersion 0.1.0.0, absolute README links, repository commit and license metadata, Source Link to the commit, the embedded SBOM of each package (identity and DLL hashes), the stamped template, template install/list/uninstall, restore sources of the isolated cache, the deployed closure with the packaged bridge hash, deps.json without workspace paths, and the instantiated template's direct SDK reference and output closure. - Measured for A21-02: the CheatEngine.SDK library of a plugin's deps.json carries sha512- (the lock value), not the SHA-512 of the repository-signed file. The consumed-sdk schema and eng/sdk/README.md now say so. - TemporaryDirectory deletion clears read-only attributes and retries instead of failing the run. Run: Release pack to artifacts/nuget, then the Client.Tests module with CHEATENGINE_CLIENT_PACKAGE_SOURCE: 42 passed (smoke included).

A workflow_dispatch started from a tag was not a dry run. It has github.ref_type == 'tag', so Test-ReleaseTag.ps1 verified the tag and wrote a version, and attest and draft-release ran: attestations were signed and a draft release was created. Only publish checked the event. - Test-ReleaseTag.ps1 takes -EventName: any event but a push writes empty outputs and a dry-run notice; a push must come from a tag. - attest, draft-release and publish share one condition: a push, a tag, this repository and a verified version. Every later job needs one of them, and no job condition uses always(), failure() or cancelled(), so a dry run skips the whole release path. 2. Release assets were matched by name only. Every pack produces other nupkg bytes (the SBOM namespace and creation time change), so a draft left by another build of the tag (the dispatch above, a re-pushed tag, Re-run all jobs after a rejected publish, or an interrupted upload) kept its stale packages. finalize-release then replaced only the tuple and SHA256SUMS and published the draft before any content check. - Compare-ReleaseAssets.ps1 lists the releases of the tag through the REST API (drafts included) and compares each asset with the local folder: same names, state 'uploaded', and the SHA-256 digest GitHub records for every upload equal to the local file. It first checks that SHA256SUMS lists exactly the other local files. - New-ReleaseDraft.ps1 keeps a draft only when it matches exactly; otherwise it deletes the draft (the tag stays; nothing of a draft is public), creates it again from this run's files and compares the result. A published release that differs fails the job before publish can push anything. - Complete-GitHubRelease.ps1 compares the draft again after replacing the tuple and SHA256SUMS, before the attestation checks and before publishing; it publishes that release by id. A re-run after publication downloads the published tuple and SHA256SUMS, so the checks describe the release as published. Also in release.yml: GH_TOKEN (contents: write) moves from the job environment of draft-release and finalize-release to the steps that call gh, so restore and dotnet test never see it, and the two "Validate the tuple" scripts set $ErrorActionPreference = 'Stop'. Tests: - ReleaseWorkflowTests.DraftAndPublishRunOnlyForTagPushesOfThisRepository now asserts the shared four-clause condition on attest, draft-release and publish, the event name passed to verify, and that no job can run after a skipped need; TheWriteTokenReachesOnlyTheStepsThatCallGitHub is new. - ReleaseScriptTests (Client.Tests, no category) run the scripts in pwsh against FakeGitHubCli.ps1, an in-memory stand-in for gh: a dispatch from a tag is a dry run; a push of a branch or a malformed tag is refused; a new draft carries exactly the run's files; a stale draft (other package bytes, an extra asset, an open upload) is deleted and recreated; a matching draft is kept; a published release that differs fails; finalize refuses a draft with a stale asset and publishes a matching one by id after the attestation checks.

SDK 1.0.0 TryScan folds that nil together with an unresolved global, a protected Lua failure and a non-object result into one false. The Client mapped that false to OperationRejected ("Cheat Engine did not return an AOB result list"), so every zero-match scan on the pinned profile was reported as a host rejection, while FirstOrNone promised null (audit F06, A10-15, A13-12, A18-25, A22-48). - AobScanHostStatus.Rejected becomes NoResultList and documents the four indistinguishable causes. - PatternScanner maps NoResultList to IndeterminateHostResult with the exact message "Cheat Engine returned no AOB result list: zero matches or a host failure (indistinguishable with CheatEngine.SDK 1.0.0).", HostEffect Completed. Classification uses the SDK status only, never error text; an empty returned list remains a real no-match success. - Fluent FirstOrNone/RequireSingle/Take propagate the failure unchanged and their XML docs now state it, plus the exhaustive-list uniqueness invariant of RequireSingle and CE result-list order for FirstOrNone. - Q27 tests: MissingAobResultListIsAmbiguousAndNotNotFound, ScanThrowsWhenTheAobResultIsAmbiguousAndNotNotFound, InvalidResultListRemainsAnInvalidHostResult, AnEmptyReturnedListIsARealNoMatchSuccess and the Fluent AobAmbiguousFalseIsNeverReportedAsNotFound.

Several docs still presented InModule, InRange and Take as if they bounded Cheat Engine's work, and the count already read from Cheat Engine was discarded (A10-10, A10-11, A13-03, A13-06, A13-13, A24-04, A24-07). - Add the companion contract IPatternScanOutcomeClient.ScanDetailed (the IMemoryBatchClient pattern; IPatternScanner and AobScanResult are unchanged) returning PatternScanOutcome: the same classification as TryScan plus PatternScanMetrics (HostMatchCount, ExaminedCount, FilteredOutCount, MaterializedCount, PatternScanScope, HostScanElapsed for the CE call only, MaterializationElapsed for count/copy/parse/ filter) with validated invariants. PatternScanScope names the only route SDK 1.0.0 offers: GlobalHostScanWithManagedFilter. - PatternScanner: one internal classification shared by TryScan, Scan and ScanDetailed; Stopwatch timestamps, no allocation for metrics; the copy loop counts examined, filtered and copied entries. - DI registers IPatternScanOutcomeClient as an alias of the PatternScanner singleton. - XML docs, Abstractions/Fluent/Core READMEs and the template now state the canonical wording: post-filters do not reduce CE scan time or memory, limits bound only the copy, FirstOrNone follows CE's unspecified result-list order, RequireSingle proves uniqueness from the exhaustive list, and a token cannot interrupt a started scan. The four scan limits are named distinctly. - BenchmarkDotNet PatternScannerMaterializationBenchmarks measures only the Client copy cost over a fake port (1k/100k/1M entries, with and without a 1 % module filter, x64 and x86 address formats); CE scan time is a C3 measurement. Core gains InternalsVisibleTo for the benchmarks. - Tests: Q28/Q29 traits on the existing post-filter, limit and cancellation tests; metrics, classification parity, CE order, address formats, outcome/metrics validation and the DI alias. --- .../PublicAPI.Unshipped.txt | 27 ++ .../CheatEngine.Client.Abstractions/README.md | 29 ++ .../Scanning/AobScanRange.cs | 3 +- .../Scanning/AobScanRequest.cs | 11 +- .../Scanning/IPatternScanOutcomeClient.cs | 22 + .../Scanning/IPatternScanner.cs | 27 ++ .../Scanning/PatternScanMetrics.cs | 108 +++++ .../Scanning/PatternScanOutcome.cs | 80 ++++ .../Scanning/PatternScanScope.cs | 19 + .../CheatEngine.Client.Core.csproj | 1 + .../Domains/PatternScanner.cs | 452 ++++++++++-------- libs/CheatEngine.Client.Core/README.md | 19 + ...EngineClientServiceCollectionExtensions.cs | 2 + libs/CheatEngine.Client.Fluent/README.md | 17 +- .../Scanning/AobScanBuilder.cs | 45 +- .../CheatEngine.Client.Templates/README.md | 3 +- .../Modules/PluginClientModule.cs | 9 +- .../content/CheatEngine.Plugin/README.md | 5 +- .../Scanning/PatternScanOutcomeTests.cs | 100 ++++ .../BenchmarkSuiteMetadata.cs | 7 +- ...PatternScannerMaterializationBenchmarks.cs | 165 +++++++ .../Domains/PatternScannerBehaviorTests.cs | 185 +++++++ ...eClientServiceCollectionExtensionsTests.cs | 46 ++ .../Scanning/AobFluentBuilderTests.cs | 16 + 24 files changed, 1177 insertions(+), 221 deletions(-) create mode 100644 libs/CheatEngine.Client.Abstractions/Scanning/IPatternScanOutcomeClient.cs create mode 100644 libs/CheatEngine.Client.Abstractions/Scanning/PatternScanMetrics.cs create mode 100644 libs/CheatEngine.Client.Abstractions/Scanning/PatternScanOutcome.cs create mode 100644 libs/CheatEngine.Client.Abstractions/Scanning/PatternScanScope.cs create mode 100644 tests/CheatEngine.Client.Abstractions.Tests/Scanning/PatternScanOutcomeTests.cs create mode 100644 tests/CheatEngine.Client.Benchmarks/PatternScannerMaterializationBenchmarks.cs diff --git a/libs/CheatEngine.Client.Abstractions/PublicAPI.Unshipped.txt b/libs/CheatEngine.Client.Abstractions/PublicAPI.Unshipped.txt index 92365ba..402311b 100644 --- a/libs/CheatEngine.Client.Abstractions/PublicAPI.Unshipped.txt +++ b/libs/CheatEngine.Client.Abstractions/PublicAPI.Unshipped.txt @@ -638,3 +638,30 @@ CheatEngine.Client.Results.CheatEngineHostEffect.Completed = 3 -> CheatEngine.Cl CheatEngine.Client.Results.CheatEngineHostEffect.NotStarted = 1 -> CheatEngine.Client.Results.CheatEngineHostEffect CheatEngine.Client.Results.CheatEngineHostEffect.Started = 2 -> CheatEngine.Client.Results.CheatEngineHostEffect CheatEngine.Client.Results.CheatEngineHostEffect.Unknown = 0 -> CheatEngine.Client.Results.CheatEngineHostEffect +CheatEngine.Client.Scanning.IPatternScanOutcomeClient +CheatEngine.Client.Scanning.IPatternScanOutcomeClient.ScanDetailed(CheatEngine.Client.Scanning.AobScanRequest request, System.Threading.CancellationToken cancellationToken = default(System.Threading.CancellationToken)) -> CheatEngine.Client.Scanning.PatternScanOutcome! +CheatEngine.Client.Scanning.PatternScanMetrics +CheatEngine.Client.Scanning.PatternScanMetrics.Equals(CheatEngine.Client.Scanning.PatternScanMetrics other) -> bool +CheatEngine.Client.Scanning.PatternScanMetrics.ExaminedCount.get -> int +CheatEngine.Client.Scanning.PatternScanMetrics.FilteredOutCount.get -> int +CheatEngine.Client.Scanning.PatternScanMetrics.HostMatchCount.get -> int +CheatEngine.Client.Scanning.PatternScanMetrics.HostScanElapsed.get -> System.TimeSpan +CheatEngine.Client.Scanning.PatternScanMetrics.MaterializationElapsed.get -> System.TimeSpan +CheatEngine.Client.Scanning.PatternScanMetrics.MaterializedCount.get -> int +CheatEngine.Client.Scanning.PatternScanMetrics.PatternScanMetrics() -> void +CheatEngine.Client.Scanning.PatternScanMetrics.PatternScanMetrics(int hostMatchCount, int examinedCount, int filteredOutCount, int materializedCount, CheatEngine.Client.Scanning.PatternScanScope scope, System.TimeSpan hostScanElapsed, System.TimeSpan materializationElapsed) -> void +CheatEngine.Client.Scanning.PatternScanMetrics.Scope.get -> CheatEngine.Client.Scanning.PatternScanScope +CheatEngine.Client.Scanning.PatternScanOutcome +CheatEngine.Client.Scanning.PatternScanOutcome.Cause.get -> CheatEngine.Client.Results.CheatEngineFailure?

Cancellation was also documented as "before the operation reaches Cheat Engine" in 36 Fluent parameters, which is false after a scan or copy has started. - Add Core SdkBoundary: Client-internal SDK work (ports, ClientLuaGlobals, TargetMemory, EngineInspection, AobScanner, Address List access, protected Lua) is wrapped; an SDK fault becomes a CheatEngineFailure mapped by exception type with the known HostEffect. Client lifecycle exceptions are never translated, an SDK fault observed after the activation ended throws CheatEngineActivationExpiredException (A10-21), and consumer code (dispatcher callbacks, codecs, ILuaOperation) keeps the same-instance rethrow rule. The fix is at the call sites, never inside SdkMainThreadDispatcher. - Patterns, Memory, Inspection, Tables and UnsafeLua use the boundary. Memory routes every primitive, byte, string and pointer-chain call through IMemoryCodecContextPort; a batch fault keeps its completed prefix with EffectState Unknown; a codec context captures port faults. - HostEffect is set where it is known: validation, budget, policy, reservation and pre-dispatch cancellation report NotStarted (including unavailable capabilities); AOB cancellation after the scan reports Completed; a partial batch write reports Started. A pre-admission cancelled batch write reports MemoryBatchWriteEffectState.NotStarted (the dispatcher guarantees the callback did not run). - Docs: the 36 Fluent cancellation parameters, ICheatEngineDispatcher (Try throws lifecycle exceptions and ArgumentNullException; callback exceptions keep their instance), and a per-family "Failure, exception and cancellation contract" table in the Abstractions README, including the honest current behavior of Runtime and Processes. - Tests: TryContractTests (activation expiry never reclassified, every SDK exception type across nine entry points, static SDK bindings without a runtime, fault after expiry, consumer rethrow, refusal before start, effect started then cancelled, partial batch, application exception) plus dispatcher and batch-dispatch tests. --- .../Dispatching/ICheatEngineDispatcher.cs | 44 +- .../CheatEngine.Client.Abstractions/README.md | 32 + .../Dispatching/SdkMainThreadDispatcher.cs | 3 + .../Events/UnavailableCapabilityFailure.cs | 7 +- .../Domains/IMemoryCodecContextPort.cs | 29 + .../Domains/InspectionClient.cs | 47 +- .../Domains/MemoryClient.cs | 458 +++++++---- .../Domains/PatternScanner.cs | 46 +- .../Domains/TableClient.cs | 62 +- .../Domains/UnavailableValueScanner.cs | 5 +- .../Domains/UnsafeLuaClient.cs | 8 +- .../Infrastructure/SdkBoundary.cs | 109 +++ libs/CheatEngine.Client.Core/README.md | 12 + .../Memory/MemoryAddressBuilder.cs | 120 ++- .../Memory/MemoryPointerChainBuilder.cs | 10 +- .../Memory/MemoryPrimitiveBatchBuilder.cs | 20 +- .../Scanning/AobFirstMatchBuilder.cs | 10 +- .../Scanning/AobManyMatchBuilder.cs | 10 +- .../Scanning/AobSingleMatchBuilder.cs | 10 +- .../SdkMainThreadDispatcherBehaviorTests.cs | 56 ++ .../MemoryClientDispatchFailureTests.cs | 35 + .../Infrastructure/TryContractTests.cs | 708 ++++++++++++++++++ 22 files changed, 1592 insertions(+), 249 deletions(-) create mode 100644 libs/CheatEngine.Client.Core/Infrastructure/SdkBoundary.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Infrastructure/TryContractTests.cs diff --git a/libs/CheatEngine.Client.Abstractions/Dispatching/ICheatEngineDispatcher.cs b/libs/CheatEngine.Client.Abstractions/Dispatching/ICheatEngineDispatcher.cs index 825172c..6de8435 100644 --- a/libs/CheatEngine.Client.Abstractions/Dispatching/ICheatEngineDispatcher.cs +++ b/libs/CheatEngine.Client.Abstractions/Dispatching/ICheatEngineDispatcher.cs @@ -5,6 +5,27 @@ namespace CheatEngine.Client.Dispatching; /// Synchronously dispatches managed work to Cheat Engine's captured main thread. +/// +/// +/// Try is not "never throws".

TableClient reports CleanupUnconfirmed ("may remain in the Address List") when the rollback is not confirmed and Completed when it is; creation and rollback faults are both kept. - Hosting records each cleanup stage (CleanupScope, ModuleCallbacks, ClientResources, Scope, Provider, Configuration) and logs event 6 per failure with the stage name and exception type name only, and event 7 with attempted/failed stage counts; event 5 no longer says "callback". Every Hosting log call is best effort, so a throwing logging provider can abort neither enable nor any cleanup stage. Event ids 1-5 keep their numbers; 6 and 7 come from the Hosting range 6-19. - The activation order (callbacks and Client resources while the SDK context is attached, then scope, provider, configuration) is unchanged. - Tests: aggregation in reverse order, single-failure identity, target selection and drain aggregation, unconfirmed/confirmed record rollback, per-stage redacted logs, and a throwing logging provider. --- .../CheatEngine.Client.Abstractions/README.md | 2 +- .../Domains/ITableRecordMutationPort.cs | 3 + .../Domains/SdkTableRecordMutationPort.cs | 78 ++++++++ .../Domains/TableClient.cs | 76 +++----- .../Domains/TableRecordCreation.cs | 28 +++ .../Infrastructure/CoreLifetime.cs | 19 +- .../Infrastructure/CoreResourceRegistry.cs | 48 ++++- .../Infrastructure/TargetSelectionLifetime.cs | 11 +- .../CheatEngineClientPlugin.cs | 170 +++++++++++++---- .../ClientHostingLog.cs | 19 +- libs/CheatEngine.Client.Hosting/README.md | 14 ++ .../Domains/TableClientCoverageTests.cs | 7 + .../Domains/TableClientMutationTests.cs | 112 +++++++++++ .../CoreLifetimeBehaviorTests.cs | 39 +++- .../CoreResourceRegistryTests.cs | 65 +++++++ .../Infrastructure/TryContractTests.cs | 5 + .../CheatEngineClientPluginTests.cs | 179 ++++++++++++++++++ 17 files changed, 770 insertions(+), 105 deletions(-) create mode 100644 libs/CheatEngine.Client.Core/Domains/TableRecordCreation.cs diff --git a/libs/CheatEngine.Client.Abstractions/README.md b/libs/CheatEngine.Client.Abstractions/README.md index 1d0434f..de4c536 100644 --- a/libs/CheatEngine.Client.Abstractions/README.md +++ b/libs/CheatEngine.Client.Abstractions/README.md @@ -148,7 +148,7 @@ dispatch and between Client-managed steps. | Memory primitives, codecs, bytes, strings, pointer chains (`IMemoryClient`) | Dispatch admission; one call is one Cheat Engine operation | `NotStarted` (budget, unsupported type), `Unknown` (SDK fault, host refusal) | A codec may perform several reads or writes; a failed write codec can leave earlier writes in place | | Memory batches (`IMemoryBatchClient`) | Dispatch admission: a `Cancelled` dispatch reports `MemoryBatchWriteEffectState.NotStarted` | `NotStarted` (admission, pre-dispatch cancellation, unsupported type), `Started` (a completed prefix persists), `Unknown` (SDK fault or other dispatch failure) | `EffectState` is authoritative: `Partial` with `CompletedCount`/`FailedIndex`, never rolled back | | Inspection and symbol leases (`IInspectionClient`) | Dispatch admission | `NotStarted` (name already reserved by this activation), `Unknown` (SDK fault) | A faulted `registerSymbol` is not claimed and not retried | -| Tables (`ITableClient`) | Dispatch admission; `Find` filters a copied snapshot | `NotStarted` (policy, invalid relationship), `Completed` (`Find` cancelled after the snapshot), `Unknown` (SDK fault, `loadTable` fault) | `loadTable` can execute table Lua | +| Tables (`ITableClient`) | Dispatch admission; `Find` filters a copied snapshot | `NotStarted` (policy, invalid relationship), `Completed` (`Find` cancelled after the snapshot, failed `Create` whose rollback was confirmed), `CleanupUnconfirmed` (record rollback not confirmed), `Unknown` (SDK fault, `loadTable` fault) | A failed `Create` destroys the partial record once and never retries; `loadTable` can execute table Lua | | Lua typed operations and modules (`ILuaClient`) | Dispatch admission | `NotStarted` (cancellation), otherwise the operation's own failure | Owned by the operation; operation exceptions are rethrown unchanged | | Unsafe Lua (`IUnsafeLuaClient`) | Dispatch admission | `NotStarted` (policy), `Unknown` (SDK fault; the script may have run partially) | The script may have run partially before a Lua error | | Runtime and Processes (`ICheatEngineRuntime`, `IProcessClient`) | Dispatch admission | Not yet reported (`Unknown`) | Current behavior: only some SDK `Engine*Exception` types are caught, so a `LuaException` from a generated binding can still escape a `Try*`; aligning these domains with the SDK boundary is scheduled with the SDK 2.0 migration work | diff --git a/libs/CheatEngine.Client.Core/Domains/ITableRecordMutationPort.cs b/libs/CheatEngine.Client.Core/Domains/ITableRecordMutationPort.cs index 2e1c7f1..7c5fc32 100644 --- a/libs/CheatEngine.Client.Core/Domains/ITableRecordMutationPort.cs +++ b/libs/CheatEngine.Client.Core/Domains/ITableRecordMutationPort.cs @@ -9,6 +9,9 @@ namespace CheatEngine.Client.Core.Domains; /// internal interface ITableRecordMutationPort { + /// Creates, initializes and optionally re-parents one record; a failed creation is rolled back once. + public TableRecordCreation TryCreate(MemoryRecordDefinition definition, out MemoryRecordSnapshot record); + public TableRecordMutationStatus TryDelete(MemoryRecordId id); public TableRecordMutationStatus TrySetParent(MemoryRecordId childId, MemoryRecordId?

The template logged the AOB match address at Information and the whole CheatEngineFailure, whose synthesized record ToString printed Message and Exception (which can embed Lua error text, symbol expressions or table paths). - CheatEngineFailure.ToString() returns only "{Kind} in {Operation} (host effect: {HostEffect})", so structured loggers that format the failure object emit no user data. The XML docs state the policy: Kind, Operation, HostEffect, counts and durations are safe; Message, Exception, addresses, values, expressions, module and file paths and Lua text are user data. PublicAPI: the shipped oblivious override stays declared and the annotated "override ...ToString() -> string!" is added to Unshipped, the exact form RS0036/RS0050 accept. - Template: the memory probe no longer logs the address; failures log kind, operation and host effect only; the content README documents the policy and how to add an explicit opt-in event. - Abstractions and Hosting READMEs document the redaction rules. - Tests: ToStringOmitsMessageAndException; ClientLoggingPolicyTests (reflection over every shipped Client assembly: no LoggerMessage event parameter may be an Address, SymbolExpression, ModuleName, failure, exception, LuaScript or file, or a string named like a path, file, script, source, message or expression; with a violating fixture so the test cannot pass vacuously); and TemplateLoggingPolicyTests applying the same rule to the packed template sources. Core still has no ILogger; Core EventIds 2000-2099 stay unused. --- .../PublicAPI.Unshipped.txt | 1 + .../CheatEngine.Client.Abstractions/README.md | 11 ++ .../Results/CheatEngineFailure.cs | 14 ++ libs/CheatEngine.Client.Hosting/README.md | 4 +- .../Modules/PluginClientModule.cs | 30 ++-- .../content/CheatEngine.Plugin/README.md | 14 +- .../Results/CheatEngineFailureTests.cs | 20 +++ .../TemplateLoggingPolicyTests.cs | 157 ++++++++++++++++++ .../Architecture/ClientAssemblyCatalog.cs | 52 ++++++ .../Architecture/ClientLoggingPolicyTests.cs | 143 ++++++++++++++++ 10 files changed, 431 insertions(+), 15 deletions(-) create mode 100644 tests/CheatEngine.Client.Repository.Tests/SourcePolicy/TemplateLoggingPolicyTests.cs create mode 100644 tests/CheatEngine.Client.Tests/Architecture/ClientAssemblyCatalog.cs create mode 100644 tests/CheatEngine.Client.Tests/Architecture/ClientLoggingPolicyTests.cs diff --git a/libs/CheatEngine.Client.Abstractions/PublicAPI.Unshipped.txt b/libs/CheatEngine.Client.Abstractions/PublicAPI.Unshipped.txt index 402311b..ff80c31 100644 --- a/libs/CheatEngine.Client.Abstractions/PublicAPI.Unshipped.txt +++ b/libs/CheatEngine.Client.Abstractions/PublicAPI.Unshipped.txt @@ -665,3 +665,4 @@ override CheatEngine.Client.Scanning.PatternScanMetrics.GetHashCode() -> int ~override CheatEngine.Client.Scanning.PatternScanMetrics.ToString() -> string static CheatEngine.Client.Scanning.PatternScanMetrics.operator !=(CheatEngine.Client.Scanning.PatternScanMetrics left, CheatEngine.Client.Scanning.PatternScanMetrics right) -> bool static CheatEngine.Client.Scanning.PatternScanMetrics.operator ==(CheatEngine.Client.Scanning.PatternScanMetrics left, CheatEngine.Client.Scanning.PatternScanMetrics right) -> bool +override CheatEngine.Client.Results.CheatEngineFailure.ToString() -> string! diff --git a/libs/CheatEngine.Client.Abstractions/README.md b/libs/CheatEngine.Client.Abstractions/README.md index de4c536..184ba05 100644 --- a/libs/CheatEngine.Client.Abstractions/README.md +++ b/libs/CheatEngine.Client.Abstractions/README.md @@ -154,6 +154,17 @@ dispatch and between Client-managed steps. | Runtime and Processes (`ICheatEngineRuntime`, `IProcessClient`) | Dispatch admission | Not yet reported (`Unknown`) | Current behavior: only some SDK `Engine*Exception` types are caught, so a `LuaException` from a generated binding can still escape a `Try*`; aligning these domains with the SDK boundary is scheduled with the SDK 2.0 migration work | | Capability-gated domains (allocations, assembly, remote execution, debugger, hotkeys, timers, speed, hashing, DBVM, value scans) | Not applicable: no Cheat Engine work is dispatched | `NotStarted` (`CapabilityUnavailable` or `Cancelled`) | None | +### Diagnostics and redaction + +`CheatEngineFailure.Kind`, `Operation`, and `HostEffect`, together with counts and durations such as +`PatternScanMetrics`, are safe to log. `CheatEngineFailure.Message` and `CheatEngineFailure.Exception`, addresses, +values, symbol expressions, module names, file paths, and Lua source or error text are **user data**: log them only on an +explicit opt-in chosen by the application. `CheatEngineFailure.ToString()` returns only +`"{Kind} in {Operation} (host effect: {HostEffect})"`, so a structured logger that formats the failure object emits no +user data by default.

Two separately maintained allowlists of SDK types allowed in public signatures both listed CheatEngine.SDK.Engine.Scanning.Aob.AobPattern, a type that does not exist in SDK 1.0.0, and nothing recorded which SDK members the Client consumes. - One allowlist: source-generators/.../ApprovedSdkClientTypes.cs is compiled by the Lua generator and linked unchanged into CheatEngine.Client.Tests (the only Client.Tests csproj change); the phantom AobPattern entry is removed. - SdkConsumerContractTests (C1, Q48): every allowlisted name resolves to a public value type of the consumed SDK and the generator uses the shared file; Abstractions, Fluent and DI reference only allowlisted SDK types (plus the documented RuntimeCapabilities debt); the SDK types and members referenced by every shipped Client assembly equal the committed ConsumedSdkSurface inventory (240 lines, printed as added/removed on drift); and the compile-only SdkApiUsage map references every consumed member with its exact signature, so a candidate SDK that renames or removes one fails to compile at a precise location. CompilerServices helpers used only by generated bindings stay in the inventory but not in the map. - SdkMappingContractTests (Core): every public EngineException subclass and LuaException, and every InspectionStatus value, map to a known failure kind; every MemoryAccessFailure is reported as a memory failure. CoreFailureFactory.GetKind and InspectionClient.TryMap are internal. - A reusable System.Reflection.Metadata reader (type/member references, IL tokens attributed to their outermost type) backs these tests and the architecture ratchet. - Verified locally that dropping an inventory line and adding a non-existent allowlisted type both fail with explicit messages. Q48 stays Partial by decision (no next-SDK leg on the Client). --- .../ApprovedSdkClientTypes.cs | 47 +++ .../CheatEngineLuaGenerator.cs | 28 +- .../SdkContract/SdkMappingContractTests.cs | 113 +++++++ .../Architecture/MetadataSurface.cs | 319 ++++++++++++++++++ .../CheatEngine.Client.Tests.csproj | 6 + .../PublicClientSignatureBoundaryTests.cs | 29 +- .../SdkContract/ConsumedSdkSurface.cs | 262 ++++++++++++++ .../SdkContract/SdkApiUsage.cs | 222 ++++++++++++ .../SdkContract/SdkConsumerContractTests.cs | 163 +++++++++ .../SdkContract/SdkSurfaceReader.cs | 70 ++++ 10 files changed, 1209 insertions(+), 50 deletions(-) create mode 100644 source-generators/CheatEngine.Client.SourceGenerators.Lua/ApprovedSdkClientTypes.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/SdkContract/SdkMappingContractTests.cs create mode 100644 tests/CheatEngine.Client.Tests/Architecture/MetadataSurface.cs create mode 100644 tests/CheatEngine.Client.Tests/SdkContract/ConsumedSdkSurface.cs create mode 100644 tests/CheatEngine.Client.Tests/SdkContract/SdkApiUsage.cs create mode 100644 tests/CheatEngine.Client.Tests/SdkContract/SdkConsumerContractTests.cs create mode 100644 tests/CheatEngine.Client.Tests/SdkContract/SdkSurfaceReader.cs diff --git a/source-generators/CheatEngine.Client.SourceGenerators.Lua/ApprovedSdkClientTypes.cs b/source-generators/CheatEngine.Client.SourceGenerators.Lua/ApprovedSdkClientTypes.cs new file mode 100644 index 0000000..fb8e1b4 --- /dev/null +++ b/source-generators/CheatEngine.Client.SourceGenerators.Lua/ApprovedSdkClientTypes.cs @@ -0,0 +1,47 @@ +namespace CheatEngine.Client.SourceGenerators.Lua; + +/// +/// The single allowlist of purely descriptive CheatEngine.SDK value types that may appear in public Client +/// signatures and in generated Client Lua results. +/// +/// +/// +/// Audit ch.11 and Q48: only immutable address values, domain enums, and descriptive snapshots without native +/// behavior may cross the Client boundary; LuaState, CEObject, Owned<T>, function +/// pointers, ABI structures, and registry references never do.

C0 tests over the compiled Client assemblies (System.Reflection.Metadata, no Client code runs), in tests/CheatEngine.Client.Tests/Architecture: - ClientAssembliesDeclareNoNativeImports: no P/Invoke, native module reference, LibraryImport/UnmanagedCallersOnly, function pointer in a signature, or NativeLibrary use; a fixture proves each form is caught. - OnlyCoreAndHostingReferenceSdkRuntimeAssemblies: Abstractions, Fluent and DI reference only CheatEngine.SDK.Engine; Core only Engine, Lua, Annotations and Hosting; Hosting only SDK.Hosting; nobody references SDK.Abi, SDK.Lua.Interop or the Client generator at runtime. - LuaGlobalBindingsAreFrozenToTheRegisteredAdr01Exceptions: the 11 existing ClientLuaGlobals bindings plus the 3 reserved for C-CORE-B (getPointerSize, targetIsX86, targetIsArm), each with a reason and the SDK 2.0 removal; only ClientLuaGlobals may declare them. - DirectLuaStateUsageIsLimitedToTheFrozenAllowlist: IL scan attributing every Lua state/runtime/reference/marshaller/generator-helper use, LuaError, raw CEObject calls, SDK owners and any SDK member taking a LuaState to its outermost type; 45 frozen uses in ClientLuaGlobals, SdkTableRecordMutationPort, UnsafeLuaClient, TableClient and SdkAobScanPort. New use fails, removed use asks to shrink the list. - ClientCodeNeverConstructsSdkOwnersOrAdoptsHandles, ClientNeverReinvokes PluginEnable, ClientAssembliesDeclareNoFinalizers, DomainTypesDoNotHoldAServiceProvider, TableClientExposesNoStreamOrByte LoadPath. - PublicClientSignatureBoundaryTests now rejects nint/nuint unless explicitly allowlisted (none) and gains PublicSignaturesRejectDisguisedNativePointers. - Repository SourcePolicy: ClientNeverClassifiesFailuresByErrorText scans libs/**/*.cs for comparisons on .Message, with a detector self-test.

The value reaches CE's readString maxlength argument unchanged, and CE 7.7 does not document whether it counts bytes or characters. Every XML doc (request, IMemoryClient, Fluent MemoryAddressBuilder) now says exactly that and calls it a host-side bound still to be qualified at C3. A new theory proves the value is forwarded unchanged for both encodings, and another pins the conservative UTF-16 admission charge (A12-12). MemoryResourceLimits and MemoryBatchLimits now name the four limit terms: maximum block size, request count per batch, maximum scratch allocation, and partial-effect state. The docs also say where each term is enforced and that an over-budget request fails before dispatch with HostEffect.NotStarted. The Abstractions and DependencyInjection READMEs carry the same vocabulary (A24-08). The existing batch-outcome tests are tagged Qualification=Q33 without rewriting them, so every effect category stays selectable as C1 evidence (A24-10, AX06-30). The Core.Tests and Client.Tests READMEs name the new TryContract, OwnershipHandoff, SdkMapping, Architecture, and SdkContract suites. --- .../Memory/IMemoryClient.cs | 5 +- .../Memory/MemoryBatchLimits.cs | 13 ++- .../Memory/MemoryResourceLimits.cs | 58 +++++++++++- .../Memory/MemoryStringReadRequest.cs | 30 ++++++- .../CheatEngine.Client.Abstractions/README.md | 23 +++++ .../README.md | 12 +++ .../Memory/MemoryAddressBuilder.cs | 20 ++++- ...lientResourceLimitsAndBatchOutcomeTests.cs | 10 +++ .../Domains/MemoryClientTests.cs | 90 +++++++++++++++++++ tests/CheatEngine.Client.Core.Tests/README.md | 7 ++ tests/CheatEngine.Client.Tests/README.md | 7 ++ 11 files changed, 264 insertions(+), 11 deletions(-) diff --git a/libs/CheatEngine.Client.Abstractions/Memory/IMemoryClient.cs b/libs/CheatEngine.Client.Abstractions/Memory/IMemoryClient.cs index d078d30..5556cae 100644 --- a/libs/CheatEngine.Client.Abstractions/Memory/IMemoryClient.cs +++ b/libs/CheatEngine.Client.Abstractions/Memory/IMemoryClient.cs @@ -54,7 +54,10 @@ public bool TryWriteBytes(MemoryBytesWriteRequest request, out CheatEngineFailur /// Writes bytes or throws on an expected host failure. public void WriteBytes(MemoryBytesWriteRequest request, CancellationToken cancellationToken = default); - /// Tries to read a string with an explicit maximum length. + /// + /// Tries to read a string bounded by , which Cheat Engine + /// receives unchanged as a host-side bound of undocumented unit. + /// public bool TryReadString(MemoryStringReadRequest request, [NotNullWhen(true)] out string? value, out CheatEngineFailure failure, CancellationToken cancellationToken = default); diff --git a/libs/CheatEngine.Client.Abstractions/Memory/MemoryBatchLimits.cs b/libs/CheatEngine.Client.Abstractions/Memory/MemoryBatchLimits.cs index 1327380..addb54e 100644 --- a/libs/CheatEngine.Client.Abstractions/Memory/MemoryBatchLimits.cs +++ b/libs/CheatEngine.Client.Abstractions/Memory/MemoryBatchLimits.cs @@ -5,8 +5,17 @@ public static class MemoryBatchLimits { /// Gets the largest number of homogeneous scalar operations accepted in one batch. /// - /// The limit bounds request copying, result materialization and the amount of work admitted to one Cheat Engine - /// main-thread dispatch.

This finishes the cleanup, applying the maintainer's split per step: - ci.yml: inline the package-set sanity check (exact nupkg/snupkg names, embedded SBOM) that Test-PackageSet.ps1 did; drop the build-info JSON manifest, test-module-inventory and coverage-baseline-ratchet steps outright (pure evidence/policy machinery with no product necessity); drop the PSScriptAnalyzer step (nothing under eng/ is PowerShell anymore); simplify the lock-files job to a plain 'dotnet restore ... --locked-mode', which already fails on a stale lock file without a bespoke verifier. - dependency-submission.yml: replace the two-job custom Component Detection wrapper with GitHub's own advanced-security/component-detection-dependency-submission-action, a standard action built for exactly this job. - release.yml: inline tag verification (SemVer + first-parent-of-main + no-republish check), CHANGELOG extraction and SBOM extraction; drop the Client release-tuple manifest entirely (release-tuple generation is rejected evidence machinery); simplify draft-release to delete-then-recreate instead of the byte-diffing wrapper; finalize- release now only verifies attestations and publishes. The actual build/attest/publish/verify sequence and NuGet trusted publishing are unchanged (confirmed against the nuget-trusted-publishing skill). - pr-policy.yml, scheduled-health.yml: deleted outright (PR title/changelog policy and scheduled-health canaries are exactly the governance machinery the maintainer named for removal; nothing is left to wire once their scripts are gone). The "PR policy" required check and the scheduled workflow's branch-protection entry no longer have a producer; that GitHub setting needs a matching update, which is out of scope here (no lot agent changes repository settings). - setup-dotnet/action.yml, zizmor.yml, dependabot.yml, CODEOWNERS: update dangling script mentions in error messages/comments and drop the CODEOWNERS rows for the deleted pr-policy.yml/eng/ci files (CommunityHealthTests.CodeOwnersNamesOnlyExistingPaths requires it). actionlint 1.7.12 and zizmor 1.30.1 --offline are clean on every changed workflow with no new findings. --- .github/CODEOWNERS | 6 - .github/actions/setup-dotnet/action.yml | 5 +- .github/dependabot.yml | 12 +- .github/workflows/ci.yml | 88 +++-- .github/workflows/dependency-submission.yml | 89 +---- .github/workflows/pr-policy.yml | 42 -- .github/workflows/release.yml | 416 ++++++++++++++------ .github/workflows/scheduled-health.yml | 157 -------- .github/zizmor.yml | 2 +- 9 files changed, 363 insertions(+), 454 deletions(-) delete mode 100644 .github/workflows/pr-policy.yml delete mode 100644 .github/workflows/scheduled-health.yml diff --git a/.github/CODEOWNERS b/.github/CODEOWNERS index 037ca25..77089b0 100644 --- a/.github/CODEOWNERS +++ b/.github/CODEOWNERS @@ -14,9 +14,3 @@ /global.json @AriusII /nuget.config @AriusII /SECURITY.md @AriusII - -# The required "PR policy" check runs the pull request's own copy of these files (inherent to pull_request events), so -# a pull request can weaken its own check: every change to them needs an explicit review. -/.github/workflows/pr-policy.yml @AriusII -/eng/ci/Test-PullRequestPolicy.ps1 @AriusII -/eng/ci/pr-policy.json @AriusII diff --git a/.github/actions/setup-dotnet/action.yml b/.github/actions/setup-dotnet/action.yml index 7b08729..2e364fb 100644 --- a/.github/actions/setup-dotnet/action.yml +++ b/.github/actions/setup-dotnet/action.yml @@ -13,8 +13,7 @@ inputs: cache: description: >- Cache the NuGet global-packages folder, keyed on every packages.lock.json.

Directory.Build.props/.targets carry three real build-error/guard messages that pointed a developer at the deleted eng/Update-LockFiles.ps1 and eng/sdk/Update-CheatEngineSdk.ps1 scripts; they now point at the plain 'dotnet restore --force-evaluate' command and at eng/CheatEngineSdk.props directly, which is what a contributor should actually run now that the wrapper scripts are gone. eng/CheatEngineSdk.props documented a bump procedure that ran eng/sdk/Update-CheatEngineSdk.ps1 and pointed at eng/sdk/README.md and docs/migration/sdk-2.0.md; describes the manual, no-script bump procedure instead, naming exactly where the reviewed SDK identity now lives (hardcoded next to its two consumers, see the next commits). RELEASING.md documented the deleted eng/release/*.ps1 scripts and the Client release tuple step by step; rewritten to describe what release.yml actually runs after the previous commit, and drops the "Client release tuple" section entirely. --- CheatEngine.Client.slnx | 29 ------------ Directory.Build.props | 2 +- Directory.Build.targets | 6 +-- RELEASING.md | 99 ++++++++++++++-------------------------- eng/CheatEngineSdk.props | 17 +++++-- 5 files changed, 51 insertions(+), 102 deletions(-) diff --git a/CheatEngine.Client.slnx b/CheatEngine.Client.slnx index b0954d8..3c6a167 100644 --- a/CheatEngine.Client.slnx +++ b/CheatEngine.Client.slnx @@ -12,40 +12,11 @@ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - diff --git a/Directory.Build.props b/Directory.Build.props index f7c87c5..9175749 100644 --- a/Directory.Build.props +++ b/Directory.Build.props @@ -33,7 +33,7 @@ <_CheatEngineClientNuGetAuditCodes>NU1900;NU1901;NU1902;NU1903;NU1904;NU1905 $(WarningsNotAsErrors);NU1900;NU1901;NU1902;NU1905 - + $(WarningsAsErrors);$(_CheatEngineClientNuGetAuditCodes) diff --git a/Directory.Build.targets b/Directory.Build.targets index 9730165..f24abec 100644 --- a/Directory.Build.targets +++ b/Directory.Build.targets @@ -85,7 +85,7 @@ <_CheatEngineClientSdkPinProblem Condition="'$(_CheatEngineClientSdkPinProblem)' == '' and $(CheatEngineSdkVersion.Contains('-'))">is a prerelease <_CheatEngineClientSdkPinProblem Condition="'$(_CheatEngineClientSdkPinProblem)' == '' and '$(_CheatEngineClientSdkPinMajor)' != '$(_CheatEngineClientSupportedSdkMajor)'">has major version $(_CheatEngineClientSdkPinMajor), but this Client supports CheatEngine.SDK $(_CheatEngineClientSupportedSdkMajor).x only <_CheatEngineClientSdkPinProblem Condition="'$(_CheatEngineClientSdkPinProblem)' == '' and !$(CheatEngineSdkVersionRange.StartsWith('[$(CheatEngineSdkVersion),'))">is not the lower bound of the declared range '$(CheatEngineSdkVersionRange)' - <_CheatEngineClientSdkPinMessage>The consumed CheatEngine.SDK version '$(CheatEngineSdkVersion)' $(_CheatEngineClientSdkPinProblem).

Replaces the file read with the same reviewed identity (content hash, nuget.org-signed SHA-512, native bridge SHA-256) hardcoded as a literal, matching shared-contracts.md §2.4 and the ConsumedSdkContentHash constant already hardcoded in Repository.Tests/LockFiles/LockFileTests.cs for the same package: the sync mechanism that kept a separate identity file current is gone, so the identity now lives next to its two consumers instead. ReleaseScriptTests.cs ran the deleted eng/release/*.ps1 scripts (Test-ReleaseTag.ps1, New-ReleaseDraft.ps1, Complete-GitHubRelease.ps1) as child processes against FakeGitHubCli.ps1, an in-memory gh stand-in; deletes both files, since the scripts they exercised no longer exist (their behavior is now inline in release.yml and covered by the workflow-contract tests instead).

Commit abd88fc dropped the Client release-tuple manifest entirely (no future release produces a CheatEngine.Client..tuple.json asset), but the compatibility issue form still asked reporters for that file's SHA-256, and IssueFormTests.CompatibilityFormRequiresTheFullReleaseTuple still asserted the field's presence, so the suite stayed green while encoding a contract for an asset that can no longer exist. Remove the release-tuple input from .github/ISSUE_TEMPLATE/compatibility.yml and the matching assertion in IssueFormTests.cs. The rest of the required tuple (client-version, sdk-version, sdk-content-hash, bridge-sha256, ...) is untouched: it identifies a compatibility report, independent of the deleted release-asset manifest. --- .github/ISSUE_TEMPLATE/compatibility.yml | 7 ------- .../Governance/IssueFormTests.cs | 1 - 2 files changed, 8 deletions(-) diff --git a/.github/ISSUE_TEMPLATE/compatibility.yml b/.github/ISSUE_TEMPLATE/compatibility.yml index bb99308..79d31dc 100644 --- a/.github/ISSUE_TEMPLATE/compatibility.yml +++ b/.github/ISSUE_TEMPLATE/compatibility.yml @@ -166,13 +166,6 @@ body: placeholder: Windows 11 24H2 x64 (26100.xxxx) validations: required: true - - type: input - id: release-tuple - attributes: - label: Release tuple manifest SHA-256 (optional) - description: >- - SHA-256 of the `CheatEngine.Client..tuple.json` release asset, when you took the packages from a - GitHub release. - type: textarea id: reproduction attributes: diff --git a/tests/CheatEngine.Client.Repository.Tests/Governance/IssueFormTests.cs b/tests/CheatEngine.Client.Repository.Tests/Governance/IssueFormTests.cs index 3115f16..2efb07a 100644 --- a/tests/CheatEngine.Client.Repository.Tests/Governance/IssueFormTests.cs +++ b/tests/CheatEngine.Client.Repository.Tests/Governance/IssueFormTests.cs @@ -80,7 +80,6 @@ public void CompatibilityFormRequiresTheFullReleaseTuple() Assert.True(problems.Count == 0, $"{CompatibilityForm}: {string.Join("; ", problems)}."); Assert.Equal(["(C0)", "(C1)", "(C2)", "(C3)", "(C4)"], Options(elements["observed-level"]).Select(LevelSuffix)); Assert.True(elements.ContainsKey("bridge-fingerprint") && !IsRequired(elements["bridge-fingerprint"])); - Assert.True(elements.ContainsKey("release-tuple") && !IsRequired(elements["release-tuple"])); } [Fact] From 1dc3ade55ffc13391ccd3ac61f9fe8ebaa9b8b0c Mon Sep 17 00:00:00 2001 From: AriusII Date: Wed, 23 Sep 2026 13:07:08 +0200 Subject: [PATCH 093/321] Stop pointing ADR-01 ratchet guidance at a deleted migration guide Resolves the review's non-blocking remarks 1 and 2. The maintainer pivot deletes docs/ from both repos and does not recreate it, so docs/migration/sdk-2.0.md will never exist in this repository. ArchitectureRatchetTests.cs still told contributors to register new ADR-01 exceptions there, and the Abstractions README still pointed readers at it "once it exists". Rephrase both to describe the ratchet as self-contained: an ADR-01 exception is registered in the ratchet list itself (name, reason, removal condition) and removed from it when the Client migrates to SDK 2.0, with no external guide to keep in sync.

the host's GetTargetArchitecture is gone. ProcessClient reads the PID first, then the local metadata, then the facts through the observer, then the PID again; a changed PID is IndeterminateHostResult, not a stale snapshot. - ProcessSnapshot stores the observed width (new 6-argument ctor, the 5-argument ctor keeps the natural width, the 3-argument ctor Unknown) and rejects a known ISA with a contradictory known width. - Selection identity is (PID, ISA, width): the epoch advances on a PID change or a known-to-different-known change; a transiently unknown fact neither advances it nor erases the last known facts. - Following C-CORE-A's SdkBoundary rule, a fault of openProcess, of the PID read or of the local catalog is returned as a classified failure (host effect Unknown) instead of being rethrown; the former test TryGetCurrentRethrowsUnexpectedHostExceptions is renamed to the new behavior and the IProcessClient XML documents ambient targets, the attach reset of the configured pointer size and the exception rule. - ILocalProcessDiagnostics and LocalProcessHost state that local metadata never describes a CEServer or file-as-process target. --- .../Processes/ILocalProcessDiagnostics.cs | 4 +- .../Processes/IProcessClient.cs | 41 ++- .../Processes/ProcessSnapshot.cs | 81 ++++- .../PublicAPI.Unshipped.txt | 1 + .../Domains/IProcessHost.cs | 14 +- .../Domains/LocalProcessHost.cs | 30 +- .../Domains/ProcessClient.cs | 156 +++++++--- .../Processes/ProcessSnapshotTests.cs | 46 +++ .../Domains/LocalProcessDiagnosticsTests.cs | 20 +- .../Domains/LocalProcessHostTests.cs | 22 ++ .../Domains/ProcessClientTests.cs | 289 +++++++++++++++++- .../SdkContract/ConsumedSdkSurface.cs | 1 - .../SdkContract/SdkApiUsage.cs | 1 - 13 files changed, 623 insertions(+), 83 deletions(-) diff --git a/libs/CheatEngine.Client.Abstractions/Processes/ILocalProcessDiagnostics.cs b/libs/CheatEngine.Client.Abstractions/Processes/ILocalProcessDiagnostics.cs index d7dacdc..7c7ca22 100644 --- a/libs/CheatEngine.Client.Abstractions/Processes/ILocalProcessDiagnostics.cs +++ b/libs/CheatEngine.Client.Abstractions/Processes/ILocalProcessDiagnostics.cs @@ -5,7 +5,9 @@ namespace CheatEngine.Client.Processes; /// Reads bounded, copied metadata from the local operating-system process catalog. /// /// This is an offline diagnostic contract.

Spike C3 D3(d) shows readPointer follows the process width, so the width source stays the process width and the configured size becomes a separate fact plus an explicit refusal, never a silent width switch. - IMemoryCodecContextPort extends the read-only ITargetArchitectureProbe (IsTarget64Bit removed); the codec context observes the facts once per invocation, PID first. PointerSize is the process width; no target, a changed target or an unobservable width throws the context's own CheatEngineOperationException (TargetNotAttached or IndeterminateHostResult, host effect NotStarted), converted back to a failure by identity only. - New public companion IMemoryPointerWidthContext exposes the process width and the raw/known configured size to application codecs. - The Client's own pointer-typed paths refuse a known mismatch before any memory access (OperationRejected, NotStarted): Address primitives, Address batches (whole batch NotStarted), pointer chains before the first hop, and the built-in Address codec through the internal ICorePointerCodecPolicy. An unobservable configured size proceeds. - ResolvePointerChain refuses a base or intermediate address beyond a 32-bit process width, naming the hop index but never the address. - C1 codec matrix: every integer width at its boundaries (2^31, 2^53, 2^53+1, 2^63, -1), NaN payloads, -0.0, subnormals, infinities, and addresses above 4 GiB. --- .../Memory/IMemoryPointerWidthContext.cs | 57 ++ .../Memory/IMemoryReadContext.cs | 21 +- .../Memory/IMemoryWriteContext.cs | 21 +- .../PublicAPI.Unshipped.txt | 5 + .../Domains/IMemoryCodecContextPort.cs | 30 +- .../Domains/MemoryClient.cs | 393 ++++++++++-- .../Domains/PointerWidthPolicy.cs | 57 ++ .../DefaultMemoryCodecs.cs | 24 +- ...lientResourceLimitsAndBatchOutcomeTests.cs | 22 +- .../Domains/MemoryClientTests.cs | 22 +- .../MemoryCodecContextLifetimeTests.cs | 36 +- .../Domains/MemoryPointerWidthTests.cs | 575 ++++++++++++++++++ .../Infrastructure/TryContractTests.cs | 22 +- .../SdkContract/SdkMappingContractTests.cs | 22 +- .../DefaultMemoryCodecsTests.cs | 230 +++++++ 15 files changed, 1462 insertions(+), 75 deletions(-) create mode 100644 libs/CheatEngine.Client.Abstractions/Memory/IMemoryPointerWidthContext.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/PointerWidthPolicy.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Domains/MemoryPointerWidthTests.cs diff --git a/libs/CheatEngine.Client.Abstractions/Memory/IMemoryPointerWidthContext.cs b/libs/CheatEngine.Client.Abstractions/Memory/IMemoryPointerWidthContext.cs new file mode 100644 index 0000000..dc8a55e --- /dev/null +++ b/libs/CheatEngine.Client.Abstractions/Memory/IMemoryPointerWidthContext.cs @@ -0,0 +1,57 @@ +using CheatEngine.SDK.Engine.Runtime; + +namespace CheatEngine.Client.Memory; + +/// +/// Companion of and that exposes the pointer-width +/// facts of the selected target to an application codec. +/// +/// +/// +/// The Client's codec contexts implement this interface; test for it with a type check +/// (context is IMemoryPointerWidthContext widths).

Every operational capability uses this gate. - Value scanning keeps its verbatim 1.0.0 reason; allocations and assembly name the missing target-bound owners; debugger, speed, hashing, DBVM, remote execution, hotkeys and timers name the missing qualified primitive. The qualification gate stays Unknown with the profile and "SDK-branch receipts never qualify the Client tuple". - Tests: package-gate matrix, Q44 gate tests, Q45 reflection over IRuntimeProbe, an IL ratchet proving probes call only read-only bindings, a ratchet that only Unavailable* types implement the allocation/assembly contracts while the SDK major is 1, the DI composition of contract-only adapters, and the embedded identity checked against consumed-sdk.json and the Core lock file. Existing Unavailable* tests carry the Q44 trait.

otherwise one setter call, never retried, then Active and AsyncProcessing are read again -> Applied, RefusedByHost (OperationRejected, host effect Started, post-change snapshot), Pending (IndeterminateHostResult, Started) or Indeterminate (InvalidHostResult, Unknown, default record). The SDK handle calls moved from TableClient to SdkTableRecordMutationPort; the Lua-usage ratchet records exactly that move. - TableRecordGeneration binds handed-out IDs to the current table load: every trusted load that reached Cheat Engine (merge or replace, even a failed one; ITableFilePort over the existing bindings) makes earlier IDs stale, and every ID-taking operation refuses a stale ID before dispatch with InvalidState / NotStarted until a snapshot observes it again. External reloads are not detected (documented; Q34 C3 stays with C-QUAL). - Selection is dispatched through the mutation port (host-visible mutation), the table snapshot through the lookup port, so find, duplicate descriptions and the materialization limit are C1-testable. - ITableClient documents ID validity, the GUI selection effect, the activation outcomes and the loadTable script prompt; the parent-guard and not-found/host-failure tests carry the Q34 trait. --- .../Tables/ITableClient.cs | 48 ++- .../Domains/ITableFilePort.cs | 41 ++ .../Domains/ITableRecordLookupPort.cs | 8 +- .../Domains/ITableRecordMutationPort.cs | 14 +- .../Domains/RecordLookupStatus.cs | 5 +- .../Domains/SdkTableRecordLookupPort.cs | 36 ++ .../Domains/SdkTableRecordMutationPort.cs | 61 ++- .../Domains/TableClient.cs | 281 +++++++++----- .../Domains/TableRecordActivation.cs | 124 ++++++ .../Domains/TableRecordGeneration.cs | 102 +++++ .../Domains/TableClientCoverageTests.cs | 13 + .../Domains/TableClientGenerationTests.cs | 365 ++++++++++++++++++ .../Domains/TableClientLookupTests.cs | 85 +++- .../Domains/TableClientMutationTests.cs | 357 ++++++++++++++++- .../Infrastructure/TryContractTests.cs | 15 + .../Architecture/ArchitectureRatchetTests.cs | 2 +- 16 files changed, 1460 insertions(+), 97 deletions(-) create mode 100644 libs/CheatEngine.Client.Core/Domains/ITableFilePort.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/TableRecordActivation.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/TableRecordGeneration.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Domains/TableClientGenerationTests.cs diff --git a/libs/CheatEngine.Client.Abstractions/Tables/ITableClient.cs b/libs/CheatEngine.Client.Abstractions/Tables/ITableClient.cs index b8849f9..cb7678d 100644 --- a/libs/CheatEngine.Client.Abstractions/Tables/ITableClient.cs +++ b/libs/CheatEngine.Client.Abstractions/Tables/ITableClient.cs @@ -6,6 +6,23 @@ namespace CheatEngine.Client.Tables; /// Reads and changes the current Cheat Engine address list through copied record snapshots. +/// +/// +/// Memory records are live Cheat Engine objects; a snapshot copies them and does not freeze them.

a name that already resolves -> OperationRejected / NotStarted; a failed check -> the mapped kind / NotStarted, nothing registered. The activation-local reservation becomes case-insensitive because Cheat Engine's case rules for user symbols are not established. - The lease resolves the name again on release: still the leased address -> unregister (Released); another address -> Replaced, left in place; no longer resolves -> ExternallyRemoved; failed check or unregister -> CleanupUnavailable, the lease stays active and Dispose throws IndeterminateHostResult / CleanupUnconfirmed so the aggregated cleanup (Q43) reports the residue.

every sink is wrapped by GuardedCoreDiagnostics, so a throwing sink never changes a result or a cleanup. - Events are emitted after the dispatched callback returned, never inside it, and carry only epochs, counts, widths, durations, enum values and closed operation/reason names: RuntimeSnapshotCaptured, CapabilityRefused (every Unavailable* adapter, value scanning, unsafe Lua policy), TargetSelectionAdvanced (PidChanged, ArchitectureChanged, WidthChanged, TargetDetached; no PID), PointerWidthMismatchRefused (primitives, batches, chains, the codec policy path), MemoryBatchCompleted, TableGenerationAdvanced, StaleRecordIdentifierRefused, RecordActivationNotApplied, SymbolRegistrationRejected, SymbolLeaseReleased, PatternScanCompleted, LuaOperationCompleted (script length for unsafe Lua only) and CoreResourceCleanupFailed (type names only). - DI implements the sink with source-generated [LoggerMessage] events, EventIds 1000-1700, one category per domain (CheatEngine.Client.Runtime, .Processes, .Memory, .Tables, .Inspection, .Scanning, .Lua, .Lifetime) so standard Logging:LogLevel filters apply; capability refusals are logged once per capability and operation per activation; provider faults from CreateLogger, IsEnabled or Log are contained. - Hosting logs EventId 20 ActivationIdentified once per enable: epoch, plugin type, Client version, consumed SDK version and content hash, loaded SDK version, package evidence and the supported host profile id, from assembly metadata only (no path, no Lua call), behind SafeLog. - Tests: scripted Core run (no emit inside a callback, bounded fields, Q46 closed names, throwing sink changes nothing), DI category/EventId, once-per-refusal, filter and Q46 redaction tests, Hosting enable identification and throwing-provider tests, and CoreReferencesNoLoggingAssembly. The consumed SDK surface gains the CheatEngineArchitecture type in DI. --- .../UnavailableAllocationClient.cs | 4 +- .../Assembly/UnavailableAssemblyClient.cs | 4 +- .../Domains/Dbvm/UnavailableDbvmClient.cs | 4 +- .../Debugger/UnavailableDebuggerClient.cs | 4 +- .../Events/UnavailableCapabilityFailure.cs | 34 +- .../Hashing/UnavailableHashingClient.cs | 4 +- .../Hotkeys/UnavailableHotkeyClient.cs | 4 +- .../Domains/InspectionClient.cs | 6 +- .../Domains/LuaClient.cs | 50 +- .../Domains/MemoryClient.cs | 72 +- .../Domains/PatternScanner.cs | 8 + .../Domains/ProcessClient.cs | 100 ++- .../UnavailableRemoteExecutionClient.cs | 4 +- .../Domains/RuntimeClient.cs | 12 +- .../Domains/Speed/UnavailableSpeedClient.cs | 4 +- .../Domains/SymbolRegistrationLease.cs | 23 +- .../Domains/TableClient.cs | 28 +- .../Domains/Timers/UnavailableTimerClient.cs | 4 +- .../Domains/UnavailableValueScanner.cs | 17 +- .../Domains/UnsafeLuaClient.cs | 15 + .../Infrastructure/ConsumedSdkIdentity.cs | 7 + .../Infrastructure/CoreLifetime.cs | 37 +- .../Infrastructure/CoreResourceRegistry.cs | 13 +- .../Infrastructure/ICoreDiagnostics.cs | 312 +++++++ .../Infrastructure/TargetSelectionLifetime.cs | 4 +- ...EngineClientServiceCollectionExtensions.cs | 6 +- .../ClientCoreDiagnosticsLog.cs | 89 ++ .../LoggerCoreDiagnostics.cs | 257 ++++++ .../CheatEngineClientPlugin.cs | 22 + .../ClientHostingLog.cs | 18 +- .../Infrastructure/CoreDiagnosticsTests.cs | 795 ++++++++++++++++++ .../TestSupport/InertCoreLifetime.cs | 4 +- .../LoggerCoreDiagnosticsTests.cs | 316 +++++++ .../CheatEngineClientPluginTests.cs | 72 +- .../Architecture/ArchitectureRatchetTests.cs | 23 + .../SdkContract/ConsumedSdkSurface.cs | 1 + 36 files changed, 2274 insertions(+), 103 deletions(-) create mode 100644 libs/CheatEngine.Client.Core/Infrastructure/ICoreDiagnostics.cs create mode 100644 libs/CheatEngine.Client.Extensions.DependencyInjection/ClientCoreDiagnosticsLog.cs create mode 100644 libs/CheatEngine.Client.Extensions.DependencyInjection/LoggerCoreDiagnostics.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Infrastructure/CoreDiagnosticsTests.cs create mode 100644 tests/CheatEngine.Client.Extensions.DependencyInjection.Tests/LoggerCoreDiagnosticsTests.cs diff --git a/libs/CheatEngine.Client.Core/Domains/Allocations/UnavailableAllocationClient.cs b/libs/CheatEngine.Client.Core/Domains/Allocations/UnavailableAllocationClient.cs index 4b2eaee..f48864a 100644 --- a/libs/CheatEngine.Client.Core/Domains/Allocations/UnavailableAllocationClient.cs +++ b/libs/CheatEngine.Client.Core/Domains/Allocations/UnavailableAllocationClient.cs @@ -4,6 +4,7 @@ using CheatEngine.Client.Core.Domains.Events;

The package gate +compares the CheatEngine.SDK identity embedded in this assembly at build time (version, source +commit and NuGet content hash, as `AssemblyMetadata`) with the informational version of the +`CheatEngine.SDK.Engine` assembly actually loaded; it reads assembly attributes only. UI/forms, +structures, Mono/IL2CPP, and ABI hooks are outside this layer. + +## Runtime facts, target selection and pointer width + +The runtime probes are read-only (`getCEVersion`, `getSystemArchitecture`, `getABI`, +`getOpenedProcessID`, `targetIs64Bit`, `targetIsX86`, `targetIsArm`, `getPointerSize`): a snapshot +never loads a driver, runs remote code, changes the target or allocates target memory. Each is a +`ClientLuaGlobals` binding generated by the CheatEngine.SDK 1.0.0 Lua binding generator and a +registered ADR-01 exception, listed for removal in the SDK 2.0 migration guide. Every observation reads the opened process identifier first and again +at the end: with no target opened, Cheat Engine reports the facts of an x64 target, and facts +observed while the target changed are discarded (`Unknown` in the runtime snapshot, +`IndeterminateHostResult` from `IProcessClient`) instead of being mixed. The +ISA comes from the x86 and ARM family facts with the 64-bit fact, never from the 64-bit fact alone. +A generated binding reports an undefined global, a raised Lua error and an unexpected result type +as the same exception with CheatEngine.SDK 1.0.0, so a failed probe is recorded as faulted evidence +with that reason and the fact stays `Unknown`. + +Cheat Engine's selected target is ambient. `ProcessClient` advances the target-selection epoch, +and releases target-bound leases, when the PID changes, when a known ISA or process width changes +to another known value, or when Cheat Engine reports no target; a fact that is transiently unknown +keeps the epoch and the last known value. Local process name and path come from the operating +system and describe local processes only. + +Codecs use the process width. When Cheat Engine's configured pointer size is known and differs from +the process width, the Client's own pointer-typed operations are refused before any memory access +(`OperationRejected`, `NotStarted`); the configured size is exposed as a fact to custom codecs. + +## Address List records and symbols + +Every trusted table load that reaches Cheat Engine advances the table generation of the activation; +a record identifier handed out before it is refused with `InvalidState` before dispatch until a new +snapshot observes it. `TrySetActive` reads the record's state before and after one setter call and +reports applied, unchanged, refused by the host, pending or indeterminate; it never retries. +Symbol registration refuses a name that already resolves, and a lease unregisters its name only +when the name still resolves to the leased address (a replaced name is left in place). Both checks +use the same CheatEngine.SDK 1.0.0 `EngineInspection.ResolveAddress` call and are best effort, not +atomic. + +## Diagnostics events + +Core has no logging dependency.

ICheatEngineDispatcher exists so workers can call the Client, so this defeated the Q34/A14-05 guarantee. The load now advances the generation inside its dispatched callback (try/finally, so a failing load that reached Cheat Engine still advances). Every dispatched lookup or mutation reads the generation on the main thread when it copies its snapshot, and TableRecordGeneration.Observe judges the snapshot by that generation: identifiers copied before a later load are recorded as stale unless a snapshot of the current load observed them. Identifier-taking operations also re-check staleness inside the dispatched callback, so an operation queued behind an in-flight load is refused with InvalidState/NotStarted without calling Cheat Engine. Diagnostics events stay outside the callbacks. C1 tests script the interleavings with a dispatcher that runs another worker's dispatched operation right before or after a callback. --- .../CheatEngine.Client.Abstractions/README.md | 7 +- .../Tables/ITableClient.cs | 6 + .../Domains/TableClient.cs | 137 ++++++++++---- .../Domains/TableRecordGeneration.cs | 55 ++++-- libs/CheatEngine.Client.Core/README.md | 8 +- .../Domains/TableClientGenerationTests.cs | 177 +++++++++++++++--- 6 files changed, 306 insertions(+), 84 deletions(-) diff --git a/libs/CheatEngine.Client.Abstractions/README.md b/libs/CheatEngine.Client.Abstractions/README.md index d97fa05..5faace0 100644 --- a/libs/CheatEngine.Client.Abstractions/README.md +++ b/libs/CheatEngine.Client.Abstractions/README.md @@ -189,9 +189,10 @@ established.

The Core build now reads the identity from files every restored checkout has: the version and NuGet content hash of the resolved CheatEngine.SDK entry of libs/CheatEngine.Client.Core/packages.lock.json (the version must equal $(CheatEngineSdkVersion) of eng/CheatEngineSdk.props), and the repository commit declared by the restored package's nuspec, taken only when the restored .nupkg.metadata content hash equals the lock value. The runtime gate still compares "{version}+{commit}" with the loaded CheatEngine.SDK.Engine informational version. CHEATENGINECLIENT9050 (target CheatEngineClientRequireConsumedSdkIdentity, before CoreCompile, design-time builds exempt) fails any non-canary build that cannot embed the identity and names the missing evidence. The SDK-side canary (CheatEngineSdkCanary=true) still embeds nothing and is not refused, so its package gate reports Unknown. Tests: ConsumedSdkIdentityEmbeddingTests compares the embedded metadata with the lock entry, the props pin and the loaded SDK assembly, and runs the guard target (committed state passes; an empty package root and a pin drift fail with CHEATENGINECLIENT9050; the canary embeds nothing and passes). TheIdentityOfThisBuildMatchesTheLoadedSdkPackage no longer accepts Unknown, InstallGuidesStateTheQualifiedHostProfile reads the content hash from the lock file, and the Lua-exception snapshot test now asserts the evidence each probe produced instead of the reason constant's own words. The migration guide no longer links the deleted identity file or prescribes the deleted scripts; the adoption checklist names the pin properties and the CLI lock regeneration order. The two slnx entries of the guide and its generator follow the base's new attribute spacing.

The observer also treated a faulted closing PID read like a different PID. It now records the fault as TargetUnconfirmed with its own evidence reason and keeps TargetChangedDuringObservation for a different PID; ProcessClient keeps IndeterminateHostResult for both but names the failed read instead of a target change.

WI-9 had recreated exactly that shape after the branch already carried the cleanup commit that removed it, so remove docs/migration/sdk-2.0.md, eng/migration/Update-SdkMigrationBreakList.ps1, the slnx entries for both, and the Repository.Tests file that gated them. Reword every reference this lot added to that guide (ClientLuaGlobals, RuntimeClient, TableRecordActivation, ITargetArchitectureProbe, IProcessClient, the Abstractions README, and the two Architecture ratchet tests) to the self-contained pattern the ratchet already uses: each ADR-01 exception names its own SDK 2.0 replacement inline instead of pointing at a file that does not exist on this branch. The O2 docs/README.md link is dropped along with it: that file no longer exists on this branch either. CONTRIBUTING.md:178 still names the deleted guide; it predates this lot (commit 5a485c1) and is a hot file, so the removal is left for the integrator (see requestsForOtherFiles). --- CheatEngine.Client.slnx | 6 - docs/migration/sdk-2.0.md | 427 ------------------ .../Update-SdkMigrationBreakList.ps1 | 330 -------------- .../Processes/IProcessClient.cs | 2 +- .../CheatEngine.Client.Abstractions/README.md | 11 +- .../Domains/ITargetArchitectureProbe.cs | 4 +- .../Domains/RuntimeClient.cs | 3 +- .../Domains/TableRecordActivation.cs | 2 +- .../Infrastructure/ClientLuaGlobals.cs | 17 +- .../Migration/SdkMigrationGuideTests.cs | 292 ------------ .../Architecture/ArchitectureRatchetTests.cs | 12 +- .../Architecture/CapabilityRatchetTests.cs | 2 +- 12 files changed, 28 insertions(+), 1080 deletions(-) delete mode 100644 docs/migration/sdk-2.0.md delete mode 100644 eng/migration/Update-SdkMigrationBreakList.ps1 delete mode 100644 tests/CheatEngine.Client.Repository.Tests/Migration/SdkMigrationGuideTests.cs diff --git a/CheatEngine.Client.slnx b/CheatEngine.Client.slnx index b0eb7fd..712474b 100644 --- a/CheatEngine.Client.slnx +++ b/CheatEngine.Client.slnx @@ -15,18 +15,12 @@ - - - - - - diff --git a/docs/migration/sdk-2.0.md b/docs/migration/sdk-2.0.md deleted file mode 100644 index fd7f344..0000000 --- a/docs/migration/sdk-2.0.md +++ /dev/null @@ -1,427 +0,0 @@ -> Recreated 2026-09 from the audit, not the historical docs/ tree. - -# Migrating CheatEngine.Client to CheatEngine.SDK 2.0 - -This page lists everything the Client must change, retest and requalify when it moves from the CheatEngine.SDK 1.0.0 -package to the CheatEngine.SDK 2.0 package.

ADR-08 requires that result to stay visible instead of being folded into "unregistered", so the Abstractions gain a handle-free outcome vocabulary: - LuaExportReleaseStatus (Removed, Replaced, Absent, Failed, NotAttempted; Unknown = 0 is contract hygiene and is refused), - LuaModuleReleaseKind (Released, PartiallyReleased, Stale; numbers equal to the SDK 2.0 LuaRegistrationReleaseKind for a one-to-one migration mapping), - LuaExportReleaseOutcome (validating readonly record struct), - LuaModuleReleaseOutcome (immutable class whose Kind and counts are computed from the export statuses; impossible shapes such as a NotAttempted export mixed with attempted ones are refused), - IOwnershipAwareLuaModule : ILuaModule with LastReleaseOutcome. The additions are additive public API recorded in PublicAPI.Unshipped.txt; no SDK type crosses the contract (the public Lua contract test now covers the new types). ILuaModule and CheatEngineLuaModuleAttribute documentation describe the generated behaviour and no longer tell implementers that generated modules call the legacy UnregisterLuaFunctions helper. The packed Abstractions README gains a short section without relative links.

Every re-parse produced a "modified" model, so the pipeline never reported Cached or Unchanged and the models rooted compilation objects (audit ch.19 validation, DoD D.3). - ModuleModel and OperationModel are equatable value models holding strings, an EquatableArray (ordinal element-wise equality with a manual hash, netstandard2.0 has no HashCode) and DiagnosticInfo (descriptor id, LocationInfo copy and string arguments). A Diagnostic is created only when the output is produced, with Location.Create(path, span, lineSpan) (https://learn.microsoft.com/dotnet/api/microsoft.codeanalysis.location.create). - Descriptors move into one internal CheatEngineLuaDiagnostics catalog with ids, titles and messages unchanged; every descriptor now carries a help link to the generator README. - Parsing, emission and the source builder are split into their own files; the boundary analysis and the shared allowlist use stay in CheatEngineLuaGenerator.cs. Emitted text is unchanged.

Disabling a plugin therefore destroyed a value a third party (a script, a table, another plugin) had put under one of the module's names after registration. The registration rollback used the same helper. The adapter now implements IOwnershipAwareLuaModule and never references UnregisterLuaFunctions (RegisterLuaFunctions is called exactly once): - Register keeps the frozen vacancy preflight (refusal before any write), refuses a second registration while the previous one is still current, publishes, then pins the published value of every export (TryGetGlobal + CreateRef). A failure after the first write rolls back ownership-aware; the thrown exception keeps the primary's type and message, and rollback failures are attached as an AggregateException whose first element is the primary. - Unregister consumes ownership before the first Lua call (a lease retry is a no-op, LastReleaseOutcome unchanged), reports Stale without any Lua operation for a registration of an earlier state, and otherwise attempts every export: nil is written only when the global still RawEquals the pinned value; Replaced and Absent globals are left untouched. Every pin is released. The outcome is published before any failure is thrown (one as is, several as an AggregateException). The algorithm is emitted once as private generic methods over a private port interface. The nested SDK port struct is the only generated code that touches LuaState (the registered ADR-01 exception, removal with the SDK 2.0 registration leases); each of its methods records Top and restores it in a finally block, reading LuaError.FromStack before that. Hint names no longer contain '@' for keyword-named types, which made the generator throw. Tests (C1, trait Qualification=Q16): LuaModuleOwnershipEndToEndTests compile the real generated module together with a second partial part that implements the private port with a managed Lua-globals double and execute RegisterCore/UnregisterCore. SdkPortStackDisciplineTests checks the stack discipline of the SDK port on the emitted syntax (no Lua fixture exists in this repository, so there is no C2). A golden snapshot, separate descriptor/projection/legacy-call checks and declaration-order stability tests complete the generator validation. --- .../CheatEngineLuaGenerator.cs | 13 + .../ModuleEmitter.cs | 590 ++++++++++++++++-- .../ModuleParser.cs | 2 +- .../OperationParser.cs | 5 +- .../README.md | 9 +- .../CheatEngineLuaGeneratorTests.cs | 61 -- .../EndToEnd/FakeLuaGlobals.cs | 313 ++++++++++ .../LuaModuleOwnershipEndToEndTests.cs | 492 +++++++++++++++ .../EndToEnd/ModuleHarness.cs | 202 ++++++ .../EndToEnd/SdkPortStackDisciplineTests.cs | 109 ++++ .../Infrastructure/IlCallScanner.cs | 97 +++ .../Snapshots/ModuleSnapshots.cs | 496 +++++++++++++++ .../Validation/IdentifierStabilityTests.cs | 109 ++++ .../Validation/ModuleContractTests.cs | 177 ++++++ 14 files changed, 2565 insertions(+), 110 deletions(-) create mode 100644 tests/CheatEngine.Client.SourceGenerators.Lua.Tests/EndToEnd/FakeLuaGlobals.cs create mode 100644 tests/CheatEngine.Client.SourceGenerators.Lua.Tests/EndToEnd/LuaModuleOwnershipEndToEndTests.cs create mode 100644 tests/CheatEngine.Client.SourceGenerators.Lua.Tests/EndToEnd/ModuleHarness.cs create mode 100644 tests/CheatEngine.Client.SourceGenerators.Lua.Tests/EndToEnd/SdkPortStackDisciplineTests.cs create mode 100644 tests/CheatEngine.Client.SourceGenerators.Lua.Tests/Infrastructure/IlCallScanner.cs create mode 100644 tests/CheatEngine.Client.SourceGenerators.Lua.Tests/Snapshots/ModuleSnapshots.cs create mode 100644 tests/CheatEngine.Client.SourceGenerators.Lua.Tests/Validation/IdentifierStabilityTests.cs create mode 100644 tests/CheatEngine.Client.SourceGenerators.Lua.Tests/Validation/ModuleContractTests.cs diff --git a/source-generators/CheatEngine.Client.SourceGenerators.Lua/CheatEngineLuaGenerator.cs b/source-generators/CheatEngine.Client.SourceGenerators.Lua/CheatEngineLuaGenerator.cs index c497b45..fc15708 100644 --- a/source-generators/CheatEngine.Client.SourceGenerators.Lua/CheatEngineLuaGenerator.cs +++ b/source-generators/CheatEngine.Client.SourceGenerators.Lua/CheatEngineLuaGenerator.cs @@ -35,6 +35,10 @@ public sealed class CheatEngineLuaGenerator : IIncrementalGenerator "CheatEngine.SDK.Engine.Objects.ICEObject"; private const int ClientBoundaryMaximumDepth = 32; + + private static readonly SymbolDisplayFormat HintNameFormat = new( + SymbolDisplayGlobalNamespaceStyle.Omitted, + SymbolDisplayTypeQualificationStyle.NameAndContainingTypesAndNamespaces); private const int ClientBoundaryMaximumNodes = 256; // The allowlist has a single source, ApprovedSdkClientTypes.cs, which CheatEngine.Client.Tests links unchanged. @@ -543,6 +547,15 @@ internal static string TypeDeclaration(INamedTypeSymbol type, bool isStatic) return accessibility + (isStatic ?

New errors from the range allocated to this lot: - CECLUA1201: two modules of one compilation export the same Lua global. One owner per global per plugin assembly (Q16); reported on the later module by file path then position, from a Collect() output over the equatable models, so the order is deterministic. - CECLUA1202: the module declares a member the generated adapter owns (Register, Unregister, Descriptor, LastReleaseOutcome, s_descriptor, the __CheatEngineLua prefix) or explicitly implements the module contract, which would bypass the generated release. Replaces opaque CS0102/CS0111 errors in generated code; nothing is generated. - CECLUA1203: a base type already implements ILuaModule or is itself a [CheatEngineLuaModule]; the generated ownership state would be bypassed. Nothing is generated. - CECLUA1204: [CheatEngineLuaModule] is not from CheatEngine.Client.Abstractions, or a [LuaFunction] on the bindings is not from CheatEngine.SDK.Annotations. Look-alike exports are never counted and nothing is generated. CECLUA1205-1209 stay unused. The ids are tracked in AnalyzerReleases.Unshipped.md and in a Diagnostics table of the generator README; the unrelated generated-comment wording no longer names the legacy unregistration helper.

The Q16 ownership check of the generated module adapter is the single registered, frozen exception of generated Client code (shared decision; removal = SDK 2.0 registration leases, tracked in docs/migration/sdk-2.0.md). Nothing bounded it: the Client architecture ratchet scans the Client assemblies, and generated module code is compiled into plugin assemblies instead. GeneratedLuaSurfaceRatchetTests emits a generated module and reads its member references with System.Reflection.Metadata (https://learn.microsoft.com/dotnet/api/system.reflection.metadata.metadatareader.memberreferences): the SDK Lua members it uses must equal the frozen list of 18 members (LuaRuntime admission, LuaState Top/SetTop/TryGetGlobal/TrySetGlobal/ IsNil/PushNil/CreateRef/TryPushRef/RawEquals, LuaRef IsCurrent/Release, LuaStatus.IsOk, LuaError.FromStack and two LuaException constructors). Any addition fails with the ADR-01 guidance; any removal asks to shrink the list. A semantic check proves that only the nested SDK port touches LuaState/LuaRef and that the runtime admission appears only in the public Register/Unregister, and operation adapters still reference no SDK Lua member. The generator README now states exactly what the code does: the ownership-aware registration and release algorithm, the frozen member list with its removal condition, the diagnostics, the limits (metamethods on _G, retained function references are Q15, C1 evidence only, no C2 in this repository, C4 through the Coexistence protocol) and the tests that back each statement. The test project README describes its folders and the Q16 trait filter. --- .../README.md | 83 +++++ .../GeneratedLuaSurfaceRatchetTests.cs | 336 ++++++++++++++++++ .../README.md | 24 +- 3 files changed, 437 insertions(+), 6 deletions(-) create mode 100644 tests/CheatEngine.Client.SourceGenerators.Lua.Tests/Architecture/GeneratedLuaSurfaceRatchetTests.cs diff --git a/source-generators/CheatEngine.Client.SourceGenerators.Lua/README.md b/source-generators/CheatEngine.Client.SourceGenerators.Lua/README.md index 1daca55..a2fdd62 100644 --- a/source-generators/CheatEngine.Client.SourceGenerators.Lua/README.md +++ b/source-generators/CheatEngine.Client.SourceGenerators.Lua/README.md @@ -14,6 +14,62 @@ legacy `UnregisterLuaFunctions`, which writes `nil` unconditionally. and strongly typed factory.

The collision refusal was already in the controlled-host protocol (PluginCollision). The second part, "A enabled, a third party replaces one of A's globals, A is disabled, the global is still the third party's", had no scenario, so the ownership-aware release could not be observed on the exact host (A20-Q16-3, A23-F12-3). The Coexistence README gains the subsection "Third-party replacement survives disable (Q16)" after the collision sequence: an explicit operator script installs a third-party function under cheatengine_client_coexistence_a_ping, A alone is disabled, six Lua assertions are recorded, the operator removes the third party and A is re-enabled and proves its marker. It states the expected result, that a Client still releasing through the legacy helper fails the first assertion (recorded as Failed, never repaired), that the generated preflight refuses to re-enable A while the third party holds the name, and that the Replaced outcome itself remains C1 evidence. The shutdown paragraph excepts the scripted third-party value from "a disabled plugin global remains". The PluginCollision README explains the two parts and keeps "do not repair". No fixture source, project, props or lock file changes; the C4 run belongs to the Client qualification lot. --- .../PluginCollision/README.md | 8 ++- .../README.md | 51 ++++++++++++++++++- 2 files changed, 56 insertions(+), 3 deletions(-) diff --git a/tests/CheatEngine.Client.LivePlugin.Coexistence/PluginCollision/README.md b/tests/CheatEngine.Client.LivePlugin.Coexistence/PluginCollision/README.md index 55b520c..a3ad17a 100644 --- a/tests/CheatEngine.Client.LivePlugin.Coexistence/PluginCollision/README.md +++ b/tests/CheatEngine.Client.LivePlugin.Coexistence/PluginCollision/README.md @@ -4,4 +4,10 @@ This plugin intentionally exports `cheatengine_client_coexistence_a_collision`, not a third positive coexistence participant.

Mutating the emitted Observe to RawEquals(-2, -2) (every export reported as owned, the F12 defect) or swapping Owned and Replaced left every behavioural test green. SdkPortDecisionTests now reads every port method through the semantic model and enumerates its execution paths as symbol-resolved steps, independent of formatting and of the if or ?: style. The expected paths pin the Q16 decisions: TryGetGlobal of the export name, a read failure reported with LuaError.FromStack, nil before any TryPushRef, an unresolvable pin, then RawEquals(-2, -1) of the global and the pinned value deciding Owned or Replaced; nil checked before CreateRef, which is the only call that creates a reference; PushNil then TrySetGlobal for a clear. ExportName is executed and must return the UTF-8 name of each descriptor export. MutatedPortsAreRejected applies seven compiling mutations (including both identity mutations) and requires the check to name exactly the mutated method, so the check cannot silently lose its teeth. Unsupported constructs in the port fail the reader instead of being skipped. Both identity mutations were also applied to ModuleEmitter itself: the Observe decision test fails for each. The stack discipline test moves next to it into SdkPort/ and reuses the same generated port. The snapshot documentation no longer presents the golden as the only test to update: a change to the port's expected paths is a Q16 contract change, recorded in the generator README and the ADR-01 entry of docs/migration/sdk-2.0.md. --- .../README.md | 5 +- .../SdkPort/GeneratedSdkPort.cs | 141 ++++++++ .../SdkPort/SdkPortDecisionTests.cs | 319 ++++++++++++++++++ .../SdkPort/SdkPortPaths.cs | 294 ++++++++++++++++ .../SdkPortStackDisciplineTests.cs | 43 +-- .../Snapshots/ModuleSnapshots.cs | 13 +- 6 files changed, 772 insertions(+), 43 deletions(-) create mode 100644 tests/CheatEngine.Client.SourceGenerators.Lua.Tests/SdkPort/GeneratedSdkPort.cs create mode 100644 tests/CheatEngine.Client.SourceGenerators.Lua.Tests/SdkPort/SdkPortDecisionTests.cs create mode 100644 tests/CheatEngine.Client.SourceGenerators.Lua.Tests/SdkPort/SdkPortPaths.cs rename tests/CheatEngine.Client.SourceGenerators.Lua.Tests/{EndToEnd => SdkPort}/SdkPortStackDisciplineTests.cs (68%) diff --git a/tests/CheatEngine.Client.SourceGenerators.Lua.Tests/README.md b/tests/CheatEngine.Client.SourceGenerators.Lua.Tests/README.md index e4e977b..97df2e1 100644 --- a/tests/CheatEngine.Client.SourceGenerators.Lua.Tests/README.md +++ b/tests/CheatEngine.Client.SourceGenerators.Lua.Tests/README.md @@ -6,11 +6,12 @@ emits the contracts that Core reserves before mutation. | Folder | What it proves | |---|---| -| `EndToEnd/` | C1 execution of the emitted ownership-aware module algorithm (Q16): a second `partial` part of the generated module implements its private port with `FakeLuaGlobals`, a managed Lua-globals double, and the real generated `RegisterCore`/`UnregisterCore` run against it. `SdkPortStackDisciplineTests` checks the stack discipline of the SDK port on the emitted syntax. | +| `EndToEnd/` | C1 execution of the emitted ownership-aware module algorithm (Q16): a second `partial` part of the generated module implements its private port with `FakeLuaGlobals`, a managed Lua-globals double, and the real generated `RegisterCore`/`UnregisterCore` run against it.

Ownership consumption order: the generated Unregister clears its owned registration before the first Lua call, but moving that assignment after the export loop left every test green, because Lua failures are returned, not thrown. FakeLuaGlobals can now throw a non-Lua exception from a read (a programming or lifecycle failure, F15), and UnregisterConsumesOwnershipEvenWhenAnSdkExceptionEscapesTheRelease proves the exception propagates as is, the later exports are not attempted, no outcome is published, and the lease retry still makes no port call. The moved assignment was verified to fail this test. Rollback status (DoD A.10): the fake published failures with the message-only LuaException constructor, so LuaException.Status was Ok everywhere. With a status-bearing primary, a failure without rollback failure is thrown itself (MemoryError kept), while a rollback failure yields the combined LuaException(string, Exception) whose status is Ok on SDK 1.0.0; the primary status stays on the first inner exception. Both are now asserted. Unsafe code: every test compilation allows unsafe code, as do all real consumers, so an accidental unsafe block in emitted code would go unnoticed. GeneratedModuleCompilesInAConsumerThatDisallowsUnsafeCode recompiles the generated module with AllowUnsafeBlocks off. The identity-based double does not model lua_rawequal type semantics; the any-type test now says so. --- .../EndToEnd/FakeLuaGlobals.cs | 40 +++++++++++- .../LuaModuleOwnershipEndToEndTests.cs | 65 +++++++++++++++++++ .../Validation/ModuleContractTests.cs | 13 ++++ 3 files changed, 115 insertions(+), 3 deletions(-) diff --git a/tests/CheatEngine.Client.SourceGenerators.Lua.Tests/EndToEnd/FakeLuaGlobals.cs b/tests/CheatEngine.Client.SourceGenerators.Lua.Tests/EndToEnd/FakeLuaGlobals.cs index a00e7e5..ce7b13a 100644 --- a/tests/CheatEngine.Client.SourceGenerators.Lua.Tests/EndToEnd/FakeLuaGlobals.cs +++ b/tests/CheatEngine.Client.SourceGenerators.Lua.Tests/EndToEnd/FakeLuaGlobals.cs @@ -88,8 +88,8 @@ public bool Released /// Log entries are read:<name>, publish:<name>, clear:<name>, /// pin:<name>#<id>, release:<name>#<id> (a current pin), /// release-noop:<name>#<id> (a stale or already released pin), and the failed variants -/// read-failed, publish-failed, clear-failed, pin-failed, release-failed.

The list now names where each member may appear, and states that the port is the only generated code that runs against the real Lua state and is proven by SdkPortDecisionTests, not by the EndToEnd tests. The Tests table maps each promise to its evidence level; the wrapper and any-type tests are presented as identity stand-ins, not Lua type coverage. Limits added: a programming or lifecycle exception from an SDK call (F15) propagates without rollback, so after a successful publication the published globals and the pins already created stay until the Lua state is destroyed (LuaRef has no finalizer), and a release stops at that export without publishing an outcome; CECLUA1202 checks only the module's own members, so a non-module base class declaring a generated member name yields CS0108 instead of a CECLUA diagnostic. Rollback status (ADR-08, DoD A.10): on CheatEngine.SDK 1.0.0 a combined LuaException cannot carry both a status and an inner exception, so its Status is Ok and the original status stays on the first inner exception. ILuaModule.Register and the README now say so. Abstractions XML docs: LuaModuleReleaseOutcome.IsComplete means that no release step failed (the SDK 2.0 meaning); a Stale release does not claim that the earlier state was cleaned up.

RegisterCore already discards the analogous stale-release result with "_ = port.Release(...)" a few lines above; UnregisterCore's stale branch was the only place still folding it into the throwing path. Discard it the same way, with a comment on why: a stale release marks the pin released without touching Lua, so no failure is possible today (LuaRef.Release only calls native code when current), and even if one existed it must not surface here. No behaviour change under the current double: FakeLuaGlobals.Release already short-circuits to a no-op before checking FailReleases when the pin is not current, so this path could not be exercised by a test without first changing the double to inject a failure on a non-current release — which would only be pinning a defensive guard against a case neither the SDK nor the double can produce.

CONTRIBUTING.md, .coderabbit.yaml, README.md, RELEASING.md, the PR template, dependabot.yml and CHANGELOG.md still described the deleted scripts, the coverage-baseline ratchet, build-info.json, PSScriptAnalyzer and the Scheduled health workflow as if they existed, and still listed "PR policy" as a second required check next to "CI / Gate". The three packaged READMEs (src/CheatEngine.Client, CheatEngine.Client.Templates and its ceplugin content) still pointed at a docs/qualification/ folder that will never exist in this repo. Reworded every one of these to match what eng/CheatEngineSdk.props, the composite setup-dotnet action and ci.yml actually do today: lock files are regenerated with `dotnet restore --force-evaluate`, the SDK pin has no bump script (the procedure is documented in the props file itself), the architecture ratchet's ADR-01 exceptions name their own SDK 2.0 replacement inline rather than pointing at a migration guide, and the only required check is `CI / Gate` (CodeRabbit's own title/changelog checks are advisory only).

A20-Q46-2 preparation). CI compiles it through the solution; it is never packed, never a test module and never loaded by CI. tests/CheatEngine.Client.LivePlugin.Qualification (x64, dynamic loading, AOT-analysed, inside Central Package Management with the pinned SDK): - QualificationPlugin composes a Lua module and four modules (first, fault, scenario, last) with an activation-scoped resource, records its own lifecycle in a bounded ledger (stage names and exception types only) and registers the Q46 log sink. - Lua functions cheatengine_client_qualification_*: status, runtime, capabilities, target_declare, aob, memory_roundtrip, memory_batch_partial, table_create, table_probe, symbol_register, symbol_release, symbol_state and logs, each returning one bounded, redacted JSON observation built with Utf8JsonWriter. Mutating ones run only behind the gate and a check that the Client observes the authorized target. - Harness/: the fail-closed gate re-implemented from the SDK LiveProbe (ce77-live-probe-v1 manifest, pinned host SHA-256 and version, live disposable target), a write guard confining writes to the driver-allocated scratch region verified through the Client inspection API, the runner's fault switch (liveprobe.fault.json), the observation writer and the capturing logger provider. The integrated SDK runner drives the plugin only with global Lua calls of static arguments, so the region file the brief described is replaced by target_declare: the driver allocates and registers the scratch symbol, the harness verifies and declares it. The fault switch is the runner's liveprobe.fault.json for the same reason. tests/CheatEngine.Client.LivePlugin.Qualification.Tests compiles the Lua-free harness files and proves the gate, write guard, fault switch, observation redaction and log capture (27 tests). Both projects are added to the solution.

Their safety rules must still be proven on every change: the gate that refuses a mutating function, the +guard that confines writes to the declared scratch region, the fault switch, the redaction of observations and logs, the +CI refusal and the isolation of the bundle build. The Lua-free harness files (`Harness/`) are compiled into this module; +the x64 plugin project itself is never referenced, because an AnyCPU test module referencing an x64 project is a +processor-architecture mismatch. The script tests start `pwsh`, which `CheatEngine.Client.Repository.Tests` may not do. + +## How it helps improve CheatEngine.Client + +- `QualificationAuthorizationTests`: the gate refuses without the exact acknowledgement, with an expired, too long-lived + or malformed manifest, on another host binary or version, for a target that is the host, has exited or has another + image, and authorizes only the declared target (`AuthorizationIsDeniedWithoutTheAcknowledgement`, + `AuthorizationIsDeniedWhenTheManifestExpired`, `AuthorizationIsDeniedWhenTheHostHashDiffers`, + `AuthorizationIsDeniedForAnotherProcessId`, `AuthorizedManifestAllowsOnlyTheDeclaredTarget`). +- `QualificationWriteGuardTests`: a write outside the declared region, for another process or without a declaration is + refused (`WritesOutsideADeclaredRegionAreRefused`, `WritesAreRefusedWhenTheDeclarationOrTheClientTargetNamesAnotherProcess`, + `AbsentDeclarationRefusesEveryWrite`). +- `QualificationFaultInjectionTests`: the runner's fault switch selects exactly one stage and is ignored without + authorization or with another schema (`FaultFileIsIgnoredWhenAuthorizationIsDenied`, + `FaultFileWithAnUnknownSchemaIsIgnoredAndReported`, `FaultFileSelectsExactlyTheRequestedStage`, + `AbsentFaultFileMeansNoFault`). +- `QualificationObservationWriterTests`: observations name their schema and never carry a local path, a failure + message or exception text, and bound address lists (`ObservationJsonHasTheSchemaIdAndNoLocalPath`, + `ObservationNeverCarriesFailureMessagesOrExceptionText`, `AddressListsAreBoundedToTheFirstAndLastEntries`). +- `CapturingLoggerProviderTests`: the Q46 sink keeps templates, never formatted messages, and counts sensitive data + (`CapturedEventsKeepTemplatesButNeverFormattedMessages`, `SensitiveHitsCountAddressesAndDeclaredValues`). +- `Scripts/ClientQualificationScriptTests`: the wrapper refuses CI before any side effect and a work root inside a git + work tree, prints the SDK runner command with `-WhatIf` without starting anything, and its helpers write an isolated + NuGet configuration, read package identities from the `.nuspec`, reject an incomplete or foreign bundle closure and + hash committed JSON with the repository's LF rule. + +## Run + +From the repository root (the script tests need PowerShell 7, `pwsh`, on `PATH`; they fail rather than skip without it, +and none of them starts Cheat Engine, touches the registry or reads the Cheat Engine installation): + +```powershell +dotnet test --project .\tests\CheatEngine.Client.LivePlugin.Qualification.Tests\CheatEngine.Client.LivePlugin.Qualification.Tests.csproj +``` diff --git a/tests/CheatEngine.Client.LivePlugin.Qualification/CheatEngine.Client.LivePlugin.Qualification.csproj b/tests/CheatEngine.Client.LivePlugin.Qualification/CheatEngine.Client.LivePlugin.Qualification.csproj new file mode 100644 index 0000000..d5ff560 --- /dev/null +++ b/tests/CheatEngine.Client.LivePlugin.Qualification/CheatEngine.Client.LivePlugin.Qualification.csproj @@ -0,0 +1,37 @@ + + + + + CheatEngine.Client.LivePlugin.Qualification + LivePlugin.Qualification + x64 + x64 + true + true + true + true + false + true + + true + + + + + + + + + + + + + diff --git a/tests/CheatEngine.Client.LivePlugin.Qualification/Harness/CapturingLoggerProvider.cs b/tests/CheatEngine.Client.LivePlugin.Qualification/Harness/CapturingLoggerProvider.cs new file mode 100644 index 0000000..c54775b --- /dev/null +++ b/tests/CheatEngine.Client.LivePlugin.Qualification/Harness/CapturingLoggerProvider.cs @@ -0,0 +1,165 @@ +using System.Text.RegularExpressions; + +using Microsoft.Extensions.Logging; + +namespace LivePlugin.Qualification.Harness; + +/// One captured log event: where it came from and its message template, never the formatted message. +internal readonly record struct CapturedLogEvent(string Category, int EventId, string?

From 01b8ec3d02bbbd848639a01cd6723ed60b750933 Mon Sep 17 00:00:00 2001 From: AriusII Date: Wed, 23 Sep 2026 15:26:11 +0200 Subject: [PATCH 132/321] Prove the qualification plugin stays ADR-01-safe and gate-guarded Round-2 review found ~1560 lines of live-memory-touching harness code (QualificationScenarios, QualificationLuaFunctions, QualificationPlugin, QualificationSession) with no regression protection at all: the 09c8b52 cleanup deleted ClientQualificationHarnessTests along with the docs/eng trees it validated, including its two properties that had nothing to do with the removed documents (Client-API-only source scan; every mutating Lua function gated). The README still asserts both with no test now proving either. QualificationPluginSourceComplianceTests reads the harness project's own .cs files as text (it cannot be project-referenced from this AnyCPU test module; see the project README) and checks: - QualificationPluginUsesOnlyTheClientApiForCheatEngineAccess: none of the harness files contain LuaState, LuaFrame, AcquireOperation, LuaRuntime, [LuaGlobal, DllImport, LibraryImport or CheatEngine.SDK.Lua. - MutatingLuaFunctionsRouteThroughTheAuthorizationGate: parses the harness README's own "Lua functions" table and, for every function it marks mutating, confirms the QualificationScenarios method it delegates to calls RunMutating. Verified both tests fail on an injected DllImport token and on a mutating function rerouted to Guarded, then confirmed clean again. --- ...ualificationPluginSourceComplianceTests.cs | 170 ++++++++++++++++++ .../README.md | 4 + 2 files changed, 174 insertions(+) create mode 100644 tests/CheatEngine.Client.LivePlugin.Qualification.Tests/QualificationPluginSourceComplianceTests.cs diff --git a/tests/CheatEngine.Client.LivePlugin.Qualification.Tests/QualificationPluginSourceComplianceTests.cs b/tests/CheatEngine.Client.LivePlugin.Qualification.Tests/QualificationPluginSourceComplianceTests.cs new file mode 100644 index 0000000..032c2ae --- /dev/null +++ b/tests/CheatEngine.Client.LivePlugin.Qualification.Tests/QualificationPluginSourceComplianceTests.cs @@ -0,0 +1,170 @@ +using System.Text.RegularExpressions; + +namespace CheatEngine.Client.LivePlugin.Qualification.Tests; + +/// +/// Lightweight source-scan proof for the two safety properties the harness project and its README assert but that +/// no compiled test previously checked: it reaches Cheat Engine only through the public Client API (ADR-01), and +/// every Lua function the README marks mutating runs through QualificationScenarios.RunMutating before it can +/// touch the live target.

Mechanical output of the second .editorconfig hardening pass, committed separately so git blame can skip it: - dotnet format style (with IDE0047, IDE0048 and IDE0059 temporarily promoted, because dotnet format ignores option-format severities) - dotnet format analyzers --exclude-diagnostics SYSLIB1054, so the deliberate DllImport fixture in ArchitectureRatchetTests stays intact - dotnet format whitespace Only parentheses for clarity and two pattern-matching rewrites change; no behaviour changes.

The _address test fields become TestAddress so they do not shadow the SDK Address type. CONTRIBUTING, the SDK pin props comment and the Client.Tests README follow the new names. No emitted generator code is renamed, so the module snapshots are unchanged. Renames only; no behaviour changes. --- CONTRIBUTING.md | 2 +- eng/CheatEngineSdk.props | 2 +- .../Dispatching/SdkMainThreadDispatcher.cs | 34 +++++------ .../Domains/MemoryClient.cs | 12 ++-- .../Domains/PatternScanner.cs | 36 +++++------ .../Domains/RuntimeClient.cs | 4 +- .../Domains/SymbolRegistrationLease.cs | 4 +- .../Domains/TableClient.cs | 16 ++--- .../Domains/UnavailableValueScanner.cs | 4 +- .../Infrastructure/ConsumedSdkIdentity.cs | 4 +- .../Domains/Events/BoundedEventStreamTests.cs | 28 ++++----- .../Domains/Events/EventStreamLeaseTests.cs | 12 ++-- .../MemoryClientBehaviorCoverageTests.cs | 18 +++--- ...lientResourceLimitsAndBatchOutcomeTests.cs | 60 +++++++++---------- .../MemoryCodecContextLifetimeTests.cs | 42 ++++++------- .../Domains/MemoryPointerWidthTests.cs | 42 ++++++------- .../Domains/TableClientGenerationTests.cs | 44 +++++++------- .../UnavailableAdvancedClientsTests.cs | 32 +++++----- .../Infrastructure/CoreDiagnosticsTests.cs | 12 ++-- .../Lua/LuaModuleRegistrationTests.cs | 2 +- .../CoexistenceDiagnostics.cs | 38 ++++++------ .../PluginA/CoexistencePluginAFunctions.cs | 4 +- .../PluginB/CoexistencePluginBFunctions.cs | 4 +- ...ualificationPluginSourceComplianceTests.cs | 4 +- .../Harness/QualificationLedger.cs | 32 +++++----- .../Harness/QualificationObservation.cs | 4 +- .../QualificationScenarios.cs | 6 +- .../QualificationSession.cs | 30 +++++----- .../Governance/CodeQlWorkflowTests.cs | 16 ++--- .../Governance/CommunityHealthTests.cs | 12 ++-- .../DependabotConfigurationTests.cs | 8 +-- .../Governance/IssueFormTests.cs | 16 ++--- .../Governance/OnlineZizmorWorkflowTests.cs | 10 ++-- .../Governance/ScorecardWorkflowTests.cs | 22 +++---- .../LockFiles/LockFileTests.cs | 6 +- .../Packaging/PackageMetadataTests.cs | 4 +- .../Packaging/PackageVersioningTests.cs | 4 +- .../Packaging/SdkPin.cs | 4 +- .../Packaging/SdkPinTests.cs | 16 ++--- .../Release/ReleaseWorkflowTests.cs | 40 ++++++------- .../Release/RepositoryDocumentsTests.cs | 6 +- .../Solution/SolutionInventoryTests.cs | 10 ++-- .../Toolchain/TestProfileTests.cs | 6 +- .../Toolchain/ToolchainPinTests.cs | 12 ++-- .../Workflows/WorkflowContractTests.cs | 46 +++++++------- .../Infrastructure/RepositoryLayout.cs | 4 +- .../Packaging/BuildGuardTests.cs | 14 ++--- .../Packaging/PackageConsumptionSmokeTests.cs | 20 +++---- .../Packaging/PackageSourceResolutionTests.cs | 8 +-- .../Packaging/PackagedClientFeedFixture.cs | 6 +- .../Packaging/SdkCanaryRecipeTests.cs | 4 +- tests/CheatEngine.Client.Tests/README.md | 18 +++--- .../ConsumedSdkIdentityEmbeddingTests.cs | 6 +- 53 files changed, 425 insertions(+), 425 deletions(-) diff --git a/CONTRIBUTING.md b/CONTRIBUTING.md index 477b663..d131806 100644 --- a/CONTRIBUTING.md +++ b/CONTRIBUTING.md @@ -142,7 +142,7 @@ dotnet restore CheatEngine.Client.slnx --locked-mode ### Runner labels Jobs run on `windows-2025` and `ubuntu-24.04`, never on a moving `-latest` label, and Dependabot does not update -`runs-on`.

From 83e7cc32e5753d350c7ef277fff46d353cea2619 Mon Sep 17 00:00:00 2001 From: AriusII Date: Thu, 24 Sep 2026 16:41:22 +0200 Subject: [PATCH 141/321] Remove the domains no CheatEngine.SDK primitive backs The Client exposed contract-only placeholders for timers, hotkeys, the debugger, the speed hack, hashing, DBVM and remote execution. No CheatEngine.SDK release provides a primitive or an owner for any of them, so each adapter could only refuse every call with CapabilityUnavailable. Publishing them in the first release would freeze the shape of an API that nothing can back yet. Remove their Abstractions namespaces (requests, leases, events, enums), the event-stream vocabulary that only they used, the Core unavailable adapters with BoundedEventStream and EventStreamLease, the seven ICheatEngineClient properties with their composition and DI registrations, the matching ClientCapabilityId statics and the RuntimeClient capability rows with their now-unused gate reasons. Allocations and Assembly keep their contract-only adapters, and value scanning is unchanged. The capability tables, the READMEs and the public API baseline drop the removed entries, and the root and Abstractions READMEs gain a "Not offered in 1.0" section. Tests, fakes, the AOT probe and the Q44 qualification probe follow; the capability-count assertions now derive the count from ClientCapabilityId instead of a literal. --- README.md | 11 +-

No CheatEngine.SDK release provides a primitive for any of them, so Core could only answer each call with CapabilityUnavailable. Shipping them in the first release would freeze the shape of members that nothing can back yet. Remove the members, the ProcessStartRequest, ProcessPauseSnapshot and ProcessPauseState types that only they used, the TryUnavailable path and start-request validation in ProcessClient, and the comment stub in the unavailable assembly adapter. The public API baseline, the XML docs that still mentioned comments, and the process and assembly tests follow. --- .../Assembly/IAssemblyClient.cs | 9 +- .../ICheatEngineClient.cs | 2 +- .../Processes/IProcessClient.cs | 37 ----- .../Processes/ProcessPauseSnapshot.cs | 34 ----- .../Processes/ProcessPauseState.cs | 14 -- .../Processes/ProcessStartRequest.cs | 43 ------ .../PublicAPI.Unshipped.txt | 40 ----- .../Runtime/ClientCapabilityId.cs | 2 +- .../Assembly/UnavailableAssemblyClient.cs | 14 -- .../Domains/ProcessClient.cs | 132 ----------------- .../Processes/ProcessSnapshotTests.cs | 22 --- .../Domains/ProcessClientTests.cs | 137 ------------------ .../UnavailableAdvancedClientsTests.cs | 5 - 13 files changed, 3 insertions(+), 488 deletions(-) delete mode 100644 libs/CheatEngine.Client.Abstractions/Processes/ProcessPauseSnapshot.cs delete mode 100644 libs/CheatEngine.Client.Abstractions/Processes/ProcessPauseState.cs delete mode 100644 libs/CheatEngine.Client.Abstractions/Processes/ProcessStartRequest.cs diff --git a/libs/CheatEngine.Client.Abstractions/Assembly/IAssemblyClient.cs b/libs/CheatEngine.Client.Abstractions/Assembly/IAssemblyClient.cs index 08e1fde..f2b5aff 100644 --- a/libs/CheatEngine.Client.Abstractions/Assembly/IAssemblyClient.cs +++ b/libs/CheatEngine.Client.Abstractions/Assembly/IAssemblyClient.cs @@ -6,7 +6,7 @@ namespace CheatEngine.Client.Assembly;

The switch kept a second, weaker build mode in the Client that nothing exercised outside its own tests. - Directory.Build.targets: CheatEngineClientValidateSdkPin raises CHEATENGINECLIENT9016 for every bad pin, and the pack guard keeps only the pin-problem refusal. The comments no longer name an SDK major. - CheatEngine.Client.Core.csproj: CHEATENGINECLIENT9050 applies to every build except design-time builds, and the consumed SDK identity is embedded whenever its evidence is complete. - ConsumedSdkIdentity: the not-embedded branch stays a defensive Unknown with a neutral reason. - eng/CheatEngineSdk.props: drop the canary paragraph of the header comment; the pin values are unchanged. - Tests: delete SdkCanaryRecipeTests and the canary cases of BuildGuardTests and ConsumedSdkIdentityEmbeddingTests, and stop passing CheatEngineSdkCanary=false to the guard runs. The major-two guard case now also runs the pack guard, which only the deleted canary case exercised. - Documentation: the test README, the Core README and the Q48 remarks of SdkConsumerContractTests no longer describe a canary. CheatEngineClientAllowUnsupportedSdk stays: it is the documented consumer opt-out of CECLIENT017, unrelated to the canary. --- Directory.Build.targets | 17 +--- eng/CheatEngineSdk.props | 9 -- .../CheatEngine.Client.Core.csproj | 15 ++- .../Infrastructure/ConsumedSdkIdentity.cs | 10 +- libs/CheatEngine.Client.Core/README.md | 3 +- .../Domains/RuntimeClientTests.cs | 4 +- .../Packaging/BuildGuardTests.cs | 29 ++---- .../Packaging/SdkCanaryRecipeTests.cs | 98 ------------------- tests/CheatEngine.Client.Tests/README.md | 14 +-- .../ConsumedSdkIdentityEmbeddingTests.cs | 22 +---- .../SdkContract/SdkConsumerContractTests.cs | 4 +- 11 files changed, 36 insertions(+), 189 deletions(-) delete mode 100644 tests/CheatEngine.Client.Tests/Packaging/SdkCanaryRecipeTests.cs diff --git a/Directory.Build.targets b/Directory.Build.targets index f24abec..dbf6c2a 100644 --- a/Directory.Build.targets +++ b/Directory.Build.targets @@ -74,8 +74,7 @@ @@ -92,12 +91,9 @@ - - <_CheatEngineClientSdkFacingLibrary>false @@ -240,9 +236,9 @@ - 1.0.0 diff --git a/libs/CheatEngine.Client.Core/CheatEngine.Client.Core.csproj b/libs/CheatEngine.Client.Core/CheatEngine.Client.Core.csproj index 83a7b2c..af25aa8 100644 --- a/libs/CheatEngine.Client.Core/CheatEngine.Client.Core.csproj +++ b/libs/CheatEngine.Client.Core/CheatEngine.Client.Core.csproj @@ -28,9 +28,8 @@ against the content hash. - SourceCommit: the repository commit that the restored package's nuspec declares, taken only when the restored package's .nupkg.metadata content hash equals the lock value (the restored package is the locked one). - The SDK-side canary build (CheatEngineSdkCanary=true) embeds nothing, so its package gate reports Unknown instead of a - false match.

After the bump of eng/CheatEngineSdk.props to 2.0.0 they would have tested the new pin itself instead of the next major.

The pin-range and template facts read the pin through the helper. - New PluginReferencingAnSdkBelowTheDeclaredRangeFailsRestoreAsync: re-versions the pinned SDK as {major-1}.99.0 (0.99.0 today). The direct reference wins over the [pin, upper bound) dependency of the SDK-facing Client packages, so NuGet reports NU1605 (package downgrade), which the .NET SDK raises as an error: the restore fails. Observed on a packed feed: "error NU1605 ...

It now reads the state with 'gh release view --json isDraft,isImmutable' and publishes the draft with 'gh release edit --draft=false'; both resolve a draft by its tag. A release that is already published, on a re-run, is verified again but never edited. After the publication the job verifies what consumers download: it downloads every asset into a temporary directory and checks them against SHA256SUMS in both directions (every line names an asset with that hash, every asset has a line). For an immutable release it runs 'gh release verify' and 'gh release verify-asset' for each package and for SHA256SUMS, which ties the other assets to the release attestation. It then verifies the provenance and SPDX SBOM attestations of each published package and writes the asset hashes to the step summary. Every 'gh attestation verify' of the workflow now pins the identity that consumers check: this repository, the release.yml signer workflow, refs/tags/ as source ref and GitHub-hosted runners, with an explicit predicate type. The finalize checkout is dropped: no step reads the working tree. ReleaseWorkflowTests gains FinalizeReadsTheReleaseWithGhReleaseViewAndPublishesWithGhReleaseEdit, which also bans the REST releases-by-tag path everywhere, and AttestationVerificationPinsSignerSourceRefAndHostedRunners. --- .github/workflows/release.yml | 154 +++++++++++++++--- .../Release/ReleaseWorkflowTests.cs | 123 ++++++++++++++ 2 files changed, 250 insertions(+), 27 deletions(-) diff --git a/.github/workflows/release.yml b/.github/workflows/release.yml index 9050c5a..a98c063 100644 --- a/.github/workflows/release.yml +++ b/.github/workflows/release.yml @@ -616,66 +616,166 @@ jobs: GH_REPO: ${{ github.repository }} TAG: ${{ github.ref_name }} VERSION: ${{ needs.verify.outputs.version }} - SIGNER_WORKFLOW: ${{ github.repository }}/.github/workflows/release.yml steps: - - name: Checkout - uses: actions/checkout@3d3c42e5aac5ba805825da76410c181273ba90b1 # v7.0.1 - with: - persist-credentials: false - - name: Download packages uses: actions/download-artifact@3e5f45b2cfb9172054b4087a40e8e0b5a5461e7c # v8.0.1 with: name: nuget-packages path: artifacts/release - # Provenance and SBOM attestations for each package, before the release becomes public. + # Provenance and SBOM attestations of each package, before the release becomes public, with the identity that + # RELEASING.md gives consumers: this repository, the release.yml signer workflow, the tag and a hosted runner. - name: Verify the attestations env: GH_TOKEN: ${{ github.token }} run: | $ErrorActionPreference = 'Stop' + $identity = @( + '--repo', 'CheatEngineNet/CheatEngine.Client', + '--signer-workflow', 'CheatEngineNet/CheatEngine.Client/.github/workflows/release.yml', + '--source-ref', "refs/tags/$env:TAG", + '--deny-self-hosted-runners' + ) $packages = @(Get-ChildItem artifacts/release -File -Filter "*.$env:VERSION.nupkg") if ($packages.Count -ne 7) { throw "Expected the seven attested packages in artifacts/release, found $($packages.Count)." } foreach ($package in $packages) { - gh attestation verify $package.FullName --repo $env:GH_REPO --signer-workflow $env:SIGNER_WORKFLOW + gh attestation verify $package.FullName @identity --predicate-type 'https://slsa.dev/provenance/v1' if ($LASTEXITCODE -ne 0) { throw "The build provenance attestation of $($package.Name) did not verify (exit code $LASTEXITCODE)." } - gh attestation verify $package.FullName --repo $env:GH_REPO --signer-workflow $env:SIGNER_WORKFLOW --predicate-type 'https://spdx.dev/Document/v2.2' + gh attestation verify $package.FullName @identity --predicate-type 'https://spdx.dev/Document/v2.2' if ($LASTEXITCODE -ne 0) { throw "The SBOM attestation of $($package.Name) did not verify (exit code $LASTEXITCODE)." } } - # Publish the checked draft, addressed by its release id: another draft of the same tag is never published by - # accident.

The id gh reports is a GraphQL node id, not the numeric REST id, so the call could not delete the draft and the re-run path failed before it created the new one (PKG-07). The step now lists the releases (drafts included for this contents: write token), fails when a published release already holds the tag, and deletes every draft on the tag with 'gh release delete --yes'. gh resolves a draft by its tag, so no release id is needed, and it keeps the git tag. GitHub allows several drafts on one tag, so each one is deleted before the draft is created again from this run's files.

SHA256SUMS is now written by attest, over the packages, the symbol packages, the SBOMs and the attestation bundles, and travels in the attestation-bundles artifact: draft-release attaches it unchanged, and publish downloads it. Before the NuGet login, publish checks that every .nupkg and .snupkg it holds has the SHA-256 that SHA256SUMS lists for it, and that every package SHA256SUMS lists is there to be pushed. The seven packages are then pushed in dependency order with --no-symbols, and the symbol packages only afterwards, both with --skip-duplicate. If the symbol push fails once the packages are live, re-running the failed publish job skips the packages as duplicates (a nuget.org version never changes) and pushes only the symbol packages again; the step comment records that recovery.

It now resolves PackageBaseAddress/3.0.0 from the nuget.org service index, forces the English CLI output it parses, and requires the nuget.org repository signature on every served package: signature type Repository, service index https://api.nuget.org/v3/index.json, and a .signature.p7s entry on top of exactly the attested entries. The entry comparison now uses ordinal keys. The provenance attestation now covers the five symbol packages as well as the seven packages. attest verifies what it has just signed, before anything is drafted or pushed: the provenance of every .nupkg and .snupkg and the SBOM attestation of every package, each against its bundle and in the repository, with the pinned identity (this repository, the release.yml signer workflow, refs/tags/, hosted runners). That check replaces the one finalize-release ran on the local artifacts after the nuget.org push; finalize-release keeps verifying what consumers download, now including the symbol packages' provenance and gh release verify-asset on them. The seven package ids are declared once, as the workflow-level PACKAGE_IDS in dependency order, and every list in release.yml derives from it: the nuget.org pre-check, the release notes, the SBOM extraction, the pushes, the publication check and the expected release assets. actions/attest takes one SBOM per call, so the seven SBOM steps are numbered and take their subject and SBOM paths from a step that maps position n of PACKAGE_IDS. In ci.yml the Pack step declares each id once, with whether it ships a symbol package. ReleaseWorkflowTests gains PackageIdsAreDeclaredOnceAndMatchThePackableProjects (both workflows, against PackageMetadataTests.PackableProjects, now internal) and VerifyPublicationResolvesTheServiceIndexAndRequiresTheRepositorySignature; the attestation test also covers the attest-time verification and the symbol packages in the provenance subject. --- .github/workflows/ci.yml | 19 +- .github/workflows/release.yml | 304 ++++++++++-------- .../Packaging/PackageMetadataTests.cs | 4 +- .../Release/ReleaseWorkflowTests.cs | 107 +++++- 4 files changed, 289 insertions(+), 145 deletions(-) diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index a1dfe76..a14da5c 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -95,12 +95,19 @@ jobs: throw "Client package creation failed with exit code $LASTEXITCODE." } - $ids = @( - 'CheatEngine.Client', 'CheatEngine.Client.Abstractions', 'CheatEngine.Client.Core', - 'CheatEngine.Client.Extensions.DependencyInjection', 'CheatEngine.Client.Fluent', 'CheatEngine.Client.Hosting', - 'CheatEngine.Client.Templates' - ) - $noSymbols = @('CheatEngine.Client', 'CheatEngine.Client.Templates') + # The seven ids, each declared once with whether it ships a symbol package (release.yml lists the same ids in + # PACKAGE_IDS). + $shipsSymbols = [ordered]@{ + 'CheatEngine.Client' = $false + 'CheatEngine.Client.Abstractions' = $true + 'CheatEngine.Client.Core' = $true + 'CheatEngine.Client.Extensions.DependencyInjection' = $true + 'CheatEngine.Client.Fluent' = $true + 'CheatEngine.Client.Hosting' = $true + 'CheatEngine.Client.Templates' = $false + } + $ids = @($shipsSymbols.Keys) + $noSymbols = @($ids | Where-Object { -not $shipsSymbols[$_] }) $nupkgs = @(Get-ChildItem artifacts/nuget -Filter '*.nupkg') $snupkgs = @(Get-ChildItem artifacts/nuget -Filter '*.snupkg') if ($nupkgs.Count -ne $ids.Count -or $snupkgs.Count -ne ($ids.Count - $noSymbols.Count)) { diff --git a/.github/workflows/release.yml b/.github/workflows/release.yml index 1957614..2cf917f 100644 --- a/.github/workflows/release.yml +++ b/.github/workflows/release.yml @@ -28,6 +28,18 @@ defaults: run: shell: pwsh +# The seven package ids, each declared once, in dependency order: every package comes after the Client packages it +# depends on, the order publish pushes them in.

A new stage job, between ci and attest, runs on every event with a read-only token (contents: read, no id-token, no secret, no gh call). It checks that nuget-packages holds exactly the seven packages of one version and symbol packages of them (on a dry run, the version MinVer gave the packages), extracts the exact bytes of the SPDX 2.2 SBOM each package embeds after checking that it describes that package and version, writes SHA256SUMS over the packages, symbol packages and SBOMs, lists them in the step summary and uploads them as the release-staging artifact. A dry run ends there. On a release, attest now needs stage, downloads its artifact and checks every staged file against the staged SHA256SUMS before it signs them, so it attests exactly what stage checked and extracts no SBOM of its own. It still writes the final SHA256SUMS once the bundles exist. release-staging joins the reserved artifact names, and the contract order in the workflow header, the tests and .coderabbit.yaml now includes stage.

Only the four sections that describe the chain change. Publish lists the eight jobs with the new stage job, PACKAGE_IDS, the checks attest runs on its own attestations, the gh release delete of stale drafts, the SHA256SUMS check before the NuGet login, the packages pushed before their symbols, the service index lookup and repository signature of verify-publication, and the gh release view and edit of finalize-release. The dry run now also runs stage, with a read-only token, and its summary and release-staging artifact show the SBOMs and checksums. Verify a release pins the identity with --signer-workflow, --source-ref and --deny-self-hosted-runners, checks the provenance of the packages and symbol packages and the SPDX predicate of each SBOM attestation, and runs gh release verify and gh release verify-asset once immutable releases are enabled, with a paragraph on what each check proves. Re-run a release records the draft deletion by tag, the finalize re-run behaviour and the recovery when the symbol push fails after the packages are live: re-run the failed publish job, whose package pushes are skipped as duplicates and whose symbol push runs again with --skip-duplicate. What a release contains notes that the provenance covers the symbol packages, that the SBOMs are extracted byte for byte and what the immutable release attestation adds.

The change is all or nothing: SdkPinTests, the lock-file facts and the packaged tests fail on any half-done bump. Pin and version line - eng/CheatEngineSdk.props: 2.0.0, upper bound 3.0.0, supported major 2. Its header names the install guides in the bump procedure and adds a "Major migration" checklist (bounds, Hosting guard, template default, identity literals, install guides, dependabot and issue forms, capability reasons and prose, lock regeneration, the .NET SDK internal _GetProjectReferenceVersions target). - Hosting's CECLIENT017 guard refuses SDK 3.x; MinVerMinimumMajorMinor is 1.0, so untagged builds are 1.0.0-alpha.0.N and the assembly version is 1.0.0.0. The template defaults are CheatEngine.Client 1.0.0 and CheatEngine.SDK 2.0.0. Lock files - Regenerated with the .NET SDK 10.0.401 CLI only, one project at a time with --force-evaluate: the three Coexistence fixtures first, then every other project with a lock file. 21 lock files change: the 20 that resolve CheatEngine.SDK, plus the template lock, whose final newline NuGet drops. Microsoft.NET.ILLink.Tasks stays in 11 locks, the AotProbe lock keeps the win-x64 ILCompiler pack, and no Coexistence lock gains a CentralTransitive entry. - LockFileTests now requires that no lock file ends with a newline (LockFilesEndExactlyAsNuGetWritesThem) and reads the SDK version from the pin. Identity - PackagedClientFeedFixture, LockFileTests, RuntimeClientTests and the three install guides state the 2.0.0 identity: content hash NLEdZ..., signed-file SHA-512 R5aMq..., packed bridge SHA-256 b008c8d8..., source commit 325c47b. The new fact SdkPinTests.RetiredSdkIdentityLiteralsAppearNowhere keeps the four 1.0.0 literals out of every text file. Code - InspectionClientBehaviorTests builds AddressResolutionOptions with Shallow only (UseHostSymbolTable was removed in SDK 2.0.0). - CoreFailureFactory gets interim arms for the exception types SDK 2.0.0 added: EngineTargetIdentityException and MemoryScanStateException map to InvalidState, the three handoff exceptions to OperationRejected with CleanupUnconfirmed when the effect is otherwise unknown. The final classification comes with the SDK 2.0 failure vocabulary. - ADR-10: value scanning, allocations and assembly take their package gate from the consumed-SDK evidence like every other capability; the contract-only implementation gate alone refuses them, with a version-neutral reason. The qualification reason names the embedded SDK identity instead of a literal, and the value-scan refusal no longer claims what the SDK provides. - CapabilityRatchetTests compares the referenced SDK major with _CheatEngineClientSupportedSdkMajor from the pin file. Prose - Every "SDK 1.0.0" sentence under src/, libs/ and templates/, and in the root and Coexistence READMEs, states either an exact 2.0.0 fact or what the Client does today (its AOB route calls the boolean AobScanner.TryScan; it binds these globals directly), never a promise. README, CHANGELOG, RELEASING (F05), CONTRIBUTING, dependabot and the issue forms follow the pin. Inventories - ConsumedSdkSurface gains the five exception types the interim arms reference. The SDK 2.0.0 generator emits the same ClientLuaGlobals surface: the same 14 bindings, so SdkApiUsage and the FrozenLuaUsage block are unchanged. --- .coderabbit.yaml | 5 +- .github/ISSUE_TEMPLATE/bug_report.yml | 4 +- .github/ISSUE_TEMPLATE/compatibility.yml | 6 +- .github/ISSUE_TEMPLATE/feature_request.yml | 2 +- .github/dependabot.yml | 6 +- CHANGELOG.md | 16 +-- CONTRIBUTING.md | 11 +- Directory.Build.props | 6 +- README.md | 35 +++--- RELEASING.md | 4 +- eng/CheatEngineSdk.props | 45 +++++-- .../Lua/ILuaModule.cs | 2 +- .../Lua/LuaExportReleaseStatus.cs | 4 +- .../Lua/LuaModuleReleaseKind.cs | 4 +- .../Lua/LuaModuleReleaseOutcome.cs | 6 +- .../Processes/IProcessClient.cs | 4 +- .../CheatEngine.Client.Abstractions/README.md | 58 +++++---- .../Scanning/IPatternScanner.cs | 6 +- .../Scanning/PatternScanOutcome.cs | 2 +- .../packages.lock.json | 8 +- .../Domains/AobScanHostStatus.cs | 8 +- .../Domains/ITargetArchitectureProbe.cs | 4 +- .../Domains/InspectionClient.cs | 2 +- .../Domains/PatternScanner.cs | 11 +- .../Domains/ProbeClassifier.cs | 4 +- .../Domains/RuntimeClient.cs | 58 +++++---- .../Domains/SdkAobScanPort.cs | 8 +- .../Domains/TableRecordActivation.cs | 5 +- .../Domains/UnavailableValueScanner.cs | 13 +- .../Infrastructure/ClientLuaGlobals.cs | 18 +-- .../Infrastructure/ConsumedSdkIdentity.cs | 6 +- .../Infrastructure/CoreFailureFactory.cs | 25 ++++ libs/CheatEngine.Client.Core/README.md | 36 +++--- .../packages.lock.json | 10 +- .../packages.lock.json | 14 +-- libs/CheatEngine.Client.Fluent/README.md | 9 +- .../Scanning/AobFirstMatchBuilder.cs | 10 +- .../Scanning/AobManyMatchBuilder.cs | 2 +- .../Scanning/AobScanBuilder.cs | 2 +- .../Scanning/AobSingleMatchBuilder.cs | 6 +- .../packages.lock.json | 10 +- libs/CheatEngine.Client.Hosting/README.md | 7 +- .../CheatEngine.Client.Hosting.targets | 2 +- .../packages.lock.json | 18 +-- src/CheatEngine.Client/README.md | 15 +-- src/CheatEngine.Client/packages.lock.json | 24 ++-- .../CheatEngine.Client.Templates/README.md | 11 +- .../CheatEngine.Plugin.csproj | 8 +- .../Modules/PluginClientModule.cs | 4 +- .../content/CheatEngine.Plugin/README.md | 12 +- .../packages.lock.json | 2 +- .../Lua/LuaModuleReleaseOutcomeTests.cs | 4 +- .../Results/CheatEngineFailureTests.cs | 2 +- .../packages.lock.json | 8 +- .../packages.lock.json | 28 ++--- .../packages.lock.json | 18 +-- .../Domains/InspectionClientBehaviorTests.cs | 3 +- .../Domains/PatternScannerBehaviorTests.cs | 2 +- .../Domains/RuntimeClientTests.cs | 111 +++++++++++------- .../Domains/UnavailableValueScannerTests.cs | 6 +- .../Infrastructure/CoreFailureFactoryTests.cs | 61 ++++++++++ .../Infrastructure/TryContractTests.cs | 2 +- tests/CheatEngine.Client.Core.Tests/README.md | 4 +- .../packages.lock.json | 12 +- .../packages.lock.json | 16 +-- .../Scanning/AobFluentBuilderTests.cs | 2 +- .../packages.lock.json | 10 +- .../packages.lock.json | 20 ++-- .../PluginA/packages.lock.json | 20 ++-- .../PluginB/packages.lock.json | 20 ++-- .../PluginCollision/packages.lock.json | 20 ++-- .../README.md | 11 +- .../packages.lock.json | 8 +- ...ine.Client.LivePlugin.Qualification.csproj | 3 +- .../README.md | 6 +- .../packages.lock.json | 20 ++-- .../DependabotConfigurationTests.cs | 18 ++- .../LockFiles/LockFileTests.cs | 60 ++++------ .../Packaging/SdkPinTests.cs | 60 +++++++++- .../README.md | 9 +- .../packages.lock.json | 16 +-- .../Architecture/ArchitectureRatchetTests.cs | 2 +- .../Architecture/CapabilityRatchetTests.cs | 12 +- .../Infrastructure/SdkPin.cs | 4 + .../Packaging/PackagedClientFeedFixture.cs | 10 +- tests/CheatEngine.Client.Tests/README.md | 2 +- .../SdkContract/ConsumedSdkSurface.cs | 8 +- .../SdkContract/SdkApiUsage.cs | 3 +- .../SdkContract/SdkConsumerContractTests.cs | 7 +- .../packages.lock.json | 26 ++-- 90 files changed, 744 insertions(+), 508 deletions(-) diff --git a/.coderabbit.yaml b/.coderabbit.yaml index 8b72cd9..653e70b 100644 --- a/.coderabbit.yaml +++ b/.coderabbit.yaml @@ -65,8 +65,9 @@ reviews: public; Client code declares a native import or binds a Lua global itself without a registered exception in the architecture ratchet (tests/CheatEngine.Client.Tests/Architecture) naming its own SDK 2.0 replacement as the removal reason; a CheatEngine.SDK version literal appears outside eng/CheatEngineSdk.props, or the pin - moves to 2.x without that being a deliberate, reviewed migration (there is no automated migration guide; the - bump procedure is documented in eng/CheatEngineSdk.props itself); or a packages.lock.json + moves to another SDK major without that being a deliberate, reviewed migration (there is no automated + migration guide; the bump procedure and the major migration checklist are documented in + eng/CheatEngineSdk.props itself); or a packages.lock.json changes without a project or package change that explains it.

The Client vocabulary had no values for them, so they could only be folded into InvalidState, OperationRejected or an Unknown effect. CheatEngineFailureKind gains TargetChanged = 17, TargetIdentityUnavailable = 18 and RuntimeChanged = 19, and CheatEngineHostEffect gains NotApplied = 5 for a documented negative result that proves nothing was applied. The values extend the existing ranges, so no published meaning moves. The internal HostEffectMapping maps every EngineEffectState value: NotStarted to NotStarted, NotApplied to NotApplied, Applied to Completed and Unknown to Unknown.

Every EngineException is classified by its own EngineFailureKind, exhaustively: ExpectedOperationFailure is OperationRejected, GlobalUnavailable and CapabilityUnavailable are CapabilityUnavailable, ProtectedLuaFailure is LuaError, BindingFailure is BindingError, MarshallingFailure is InvalidHostResult, TargetIdentityUnavailable is TargetIdentityUnavailable and TargetIdentityMismatch is TargetChanged. A category this Client does not know is Unknown, and the totality tests fail until it is mapped. The three ownership handoff exceptions keep BindingFailure and record CleanupUnconfirmed when the effect is otherwise unknown. MemoryScanStateException is InvalidState and MemoryScanException is classified by its MemoryScanFailureKind, RuntimeInvalidated becoming RuntimeChanged. The L5 interim arms are gone. LuaAdmission is the single point where Core asks the SDK to admit Lua work, over LuaRuntime.TryAcquireOperationWithOutcome. Only Admitted succeeds; Detached and TransitionInProgress are ActivationExpired, ExternalStateReset is RuntimeChanged, ThreadNotAdmitted and NoStateForThread are InvalidState ("Client bug: called off the main thread"), and Unknown or an unrecognized status is InvalidState. Every refusal is NotStarted and never OperationRejected. LuaRuntime is a static SDK class, so the classification is a pure function tested for every status. UnsafeLuaClient and the parent-chain read of SdkTableRecordMutationPort now go through it; the port has no failure channel, so a refusal travels as an internal LuaAdmissionRefusedException whose classified kind CoreFailureFactory keeps. SdkBoundary reports an otherwise unclassified InvalidOperationException as RuntimeChanged once LuaRuntime.ExternalStateResetDetected is set, because every SDK admission path then refuses with that exception. CancellationMapping names the two cancellation points: before the native call is Cancelled/NotStarted, after it is Cancelled/Completed with nothing published; the dispatcher, AOB scan and table search use it. Ratchets move with the code. FrozenLuaUsage trades the two throwing LuaRuntime.AcquireOperation uses of UnsafeLuaClient and SdkTableRecordMutationPort for the single TryAcquireOperationWithOutcome use of LuaAdmission (a registered 1:1 exchange of the admission call) and records the ExternalStateResetDetected read the reset rule needs; the list keeps its size, and both typed SDK members move to the sanctioned SDK surface in the next commit. ConsumedSdkSurface and SdkApiUsage follow the printed inventory. The new MappingTotality test helper proves totality over EngineFailureKind, MemoryScanFailureKind, LuaAdmissionStatus and EngineEffectState, and every public SDK exception type maps to a known kind. TryContractTests prove that a refused admission is ActivationExpired, InvalidState or RuntimeChanged, and that an InvalidOperationException after a reset is RuntimeChanged. --- .../CheatEngine.Client.Abstractions/README.md | 6 +- .../Domains/PatternScanner.cs | 9 +- .../Domains/SdkTableRecordMutationPort.cs | 19 ++- .../Domains/TableClient.cs | 5 +- .../Domains/UnsafeLuaClient.cs | 35 +++-- .../Infrastructure/CancellationMapping.cs | 62 +++++++++ .../Infrastructure/CoreFailureFactory.cs | 97 +++++++++---- .../Infrastructure/LuaAdmission.cs | 131 ++++++++++++++++++ .../LuaAdmissionRefusedException.cs | 30 ++++ .../Infrastructure/SdkBoundary.cs | 36 ++++- libs/CheatEngine.Client.Core/README.md | 13 +- .../SdkTableRecordMutationPortTests.cs | 15 ++ .../CancellationMappingTests.cs | 113 +++++++++++++++ .../Infrastructure/CoreFailureFactoryTests.cs | 114 +++++++++++++-- .../Infrastructure/LuaAdmissionTests.cs | 101 ++++++++++++++ .../Infrastructure/TryContractTests.cs | 81 ++++++++++- .../Lua/UnsafeLuaClientTests.cs | 30 ++++ .../SdkContract/SdkMappingContractTests.cs | 112 +++++++++++++-- .../TestSupport/MappingTotality.cs | 46 ++++++ .../Architecture/ArchitectureRatchetTests.cs | 6 +- .../SdkContract/ConsumedSdkSurface.cs | 12 +- .../SdkContract/SdkApiUsage.cs | 9 ++ 22 files changed, 998 insertions(+), 84 deletions(-) create mode 100644 libs/CheatEngine.Client.Core/Infrastructure/CancellationMapping.cs create mode 100644 libs/CheatEngine.Client.Core/Infrastructure/LuaAdmission.cs create mode 100644 libs/CheatEngine.Client.Core/Infrastructure/LuaAdmissionRefusedException.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Infrastructure/CancellationMappingTests.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Infrastructure/LuaAdmissionTests.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/TestSupport/MappingTotality.cs diff --git a/libs/CheatEngine.Client.Abstractions/README.md b/libs/CheatEngine.Client.Abstractions/README.md index 9666e32..6f980d8 100644 --- a/libs/CheatEngine.Client.Abstractions/README.md +++ b/libs/CheatEngine.Client.Abstractions/README.md @@ -217,7 +217,9 @@ replaced it, left in place), `ExternallyRemoved` or `CleanupUnavailable` (nothin - **Returned as `CheatEngineFailure`:** request refusals, policy refusals, budget refusals, pre-admission cancellation, Cheat Engine results that are false, absent, indeterminate, or malformed, and every CheatEngine.SDK exception raised by - Client-internal SDK work (mapped by exception type, never by message text).

With SDK 2.0.0 consumed, that reason is void, and the typed SDK API the Client must use (admission, owners) sat in the same list as raw Lua debt. The ratchet is split into two exact inventories. LuaUsageScanner shrinks to a reporter: it lists every use of the scoped SDK surface and no longer decides what is forbidden. SanctionedSdkLuaSurface names the eight typed SDK members the Client uses, each with its reason: LuaRuntime.TryAcquireOperationWithOutcome (LuaAdmission only), LuaRuntime.ExternalStateResetDetected (SdkBoundary only), the Dispose and State of LuaRuntimeOperation, Owned.Dispose (swapped 1:1 for ReleaseWithOutcome in L11) and Value, and StringList.TryGetCount and TryGetItem. FrozenLuaUsage becomes a list of records (usage, reason, kind) and shrinks from 45 to 33 entries: the 12 sanctioned uses leave it. Only UnsafeLuaClient is Permanent, because CheatEngine.SDK 2.0.0 exposes no protected chunk-execution service; the mutation port and the ClientLuaGlobals code are Transitional to AddressListMutations and CheatTableFiles in L13; the Count read of TableClient awaits a MemoryRecord child-count getter. Each FrozenLuaGlobals entry names its replacing SDK member and lot, for example "RuntimeProcessOperations.ObserveCurrent (L9)", and the test resolves every replacement in the consumed SDK assemblies. ADR-06 also forbids every public SDK Abandon member, including MemoryScanSession.Abandon; a test enumerates them in the consumed SDK. SdkExperimentalApiRatchetTests reads every [Experimental] type and member of the referenced SDK assemblies and fails on any Client reference to one. Its floor proves the scan is not vacuous: LuaRuntime.AdmitWorkerThreads (CESDK5001), MemoryScanSession.TryWaitForCompletion and TryTerminateScan (CESDK5010), the deadline overload of AobScanner.TryScanWithinBounds (CESDK5010) and AobScanner.TryFindFirstFoundWithinBounds (CESDK5011), while the overload without a deadline stays stable. A text scan rejects CESDK5xxx suppressions in pragmas, SuppressMessage attributes, NoWarn and WarningsNotAsErrors, editorconfig and globalconfig severities and response files; comments may still cite the identifiers. sonar.yml drops docs/**, a folder the repository does not have, from both exclusion lists and restates the per-file coverage exclusion policy. SonarWorkflowTests keeps every excluded path real and shipping code excluded file by file. The ratchet rule in .coderabbit.yaml and CONTRIBUTING.md now asks for the reason and the replacing or missing SDK primitive instead of an "SDK 2.0 replacement". --- .coderabbit.yaml | 19 +- .github/workflows/sonar.yml | 19 +- CONTRIBUTING.md | 5 +- .../Workflows/SonarWorkflowTests.cs | 73 +++ .../Architecture/ArchitectureRatchetTests.cs | 457 ++++++++++++++---- .../Architecture/ConsumedSdkAssemblies.cs | 37 ++ .../Architecture/LuaUsageScanner.cs | 59 ++- .../Architecture/MetadataSurface.cs | 37 ++ .../SdkExperimentalApiRatchetTests.cs | 408 ++++++++++++++++ 9 files changed, 978 insertions(+), 136 deletions(-) create mode 100644 tests/CheatEngine.Client.Repository.Tests/Workflows/SonarWorkflowTests.cs create mode 100644 tests/CheatEngine.Client.Tests/Architecture/ConsumedSdkAssemblies.cs create mode 100644 tests/CheatEngine.Client.Tests/Architecture/SdkExperimentalApiRatchetTests.cs diff --git a/.coderabbit.yaml b/.coderabbit.yaml index 653e70b..d0abe1e 100644 --- a/.coderabbit.yaml +++ b/.coderabbit.yaml @@ -63,12 +63,13 @@ reviews: activation-bound handle or another SDK ownership type, or an SDK type outside the allowlist of tests/CheatEngine.Client.Tests/PublicClientSignatureBoundaryTests.cs; a Core implementation type becomes public; Client code declares a native import or binds a Lua global itself without a registered exception in - the architecture ratchet (tests/CheatEngine.Client.Tests/Architecture) naming its own SDK 2.0 replacement as - the removal reason; a CheatEngine.SDK version literal appears outside eng/CheatEngineSdk.props, or the pin - moves to another SDK major without that being a deliberate, reviewed migration (there is no automated - migration guide; the bump procedure and the major migration checklist are documented in - eng/CheatEngineSdk.props itself); or a packages.lock.json - changes without a project or package change that explains it.

It stays a single method with one optional parameter, so no overload group with optional parameters appears (RS0026/RS0027). The mapping depends only on the failure kind: Cancelled throws the new sealed CheatEngineOperationCanceledException, an OperationCanceledException that carries the complete failure and the observed token; ActivationExpired and InvalidState keep their dedicated exceptions; every other kind, including one this version does not define, throws CheatEngineOperationException; and the default failure, which no operation returns, throws InvalidOperationException. Every throwing form in Core (memory, patterns, inspection, tables, processes, runtime, Lua, unsafe Lua, dispatcher and the capability- gated clients) and the three Fluent AOB Execute terminals now throw through failure.Throw(cancellationToken). The Fluent terminals used to wrap every failure, including an expired activation, in CheatEngineOperationException; they now follow the same mapping. The Abstractions README documents the mapping table, and the dispatcher's Invoke forms document the cancellation exception. CheatEngineFailureTests cover each kind and the default failure; TryContractTests prove that the throwing form of patterns, memory, tables, Lua and the dispatcher raises the cancellation exception with its Try form's failure and the caller's token; PatternScanner, memory, table, dispatcher, value-scanner and Fluent AOB tests assert the new exception type. Test doubles pass their token to Throw. --- .../Dispatching/ICheatEngineDispatcher.cs | 12 ++- .../PublicAPI.Unshipped.txt | 4 +- .../CheatEngine.Client.Abstractions/README.md | 22 ++++- .../Results/CheatEngineFailure.cs | 70 ++++++++++++--- .../CheatEngineOperationCanceledException.cs | 35 ++++++++ .../Dispatching/SdkMainThreadDispatcher.cs | 8 +- .../UnavailableAllocationClient.cs | 2 +- .../Assembly/UnavailableAssemblyClient.cs | 10 +-- .../Events/UnavailableCapabilityFailure.cs | 4 +- .../Domains/InspectionClient.cs | 16 ++-- .../Domains/LocalProcessDiagnostics.cs | 2 +- .../Domains/LuaClient.cs | 10 +-- .../Domains/MemoryClient.cs | 22 ++--- .../Domains/PatternScanner.cs | 2 +- .../Domains/ProcessClient.cs | 8 +- .../Domains/RuntimeClient.cs | 6 +- .../Domains/TableClient.cs | 30 +++---- .../Domains/UnavailableValueScanner.cs | 6 +- .../Domains/UnsafeLuaClient.cs | 2 +- .../Scanning/AobFirstMatchBuilder.cs | 11 ++- .../Scanning/AobManyMatchBuilder.cs | 15 +++- .../Scanning/AobSingleMatchBuilder.cs | 11 ++- .../Lua/LuaContractTests.cs | 2 +- .../Results/CheatEngineFailureTests.cs | 89 +++++++++++++++++-- .../SdkMainThreadDispatcherTests.cs | 4 +- .../MemoryClientBehaviorCoverageTests.cs | 28 +++++- .../MemoryClientDispatchFailureTests.cs | 4 +- .../Domains/MemoryClientTests.cs | 4 +- .../MemoryCodecContextLifetimeTests.cs | 4 +- .../Domains/MemoryPointerWidthTests.cs | 4 +- .../Domains/PatternScannerBehaviorTests.cs | 31 +++++++ .../Domains/ProcessClientTests.cs | 4 +- .../Domains/RuntimeClientTests.cs | 4 +- .../Domains/SymbolRegistrationLeaseTests.cs | 4 +- .../Domains/TableClientCoverageTests.cs | 4 +- .../Domains/TableClientGenerationTests.cs | 4 +- .../Domains/TableClientLookupTests.cs | 24 ++++- .../Domains/TableClientMutationTests.cs | 4 +- ...lableValueScannerExceptionCoverageTests.cs | 4 +- .../Infrastructure/TryContractTests.cs | 48 ++++++++++ .../Lua/LuaClientTests.cs | 8 +- .../Lua/LuaModuleRegistrationTests.cs | 8 +- ...eClientServiceCollectionExtensionsTests.cs | 4 +- .../Scanning/AobFluentBuilderTests.cs | 55 +++++++++++- 44 files changed, 524 insertions(+), 129 deletions(-) create mode 100644 libs/CheatEngine.Client.Abstractions/Results/CheatEngineOperationCanceledException.cs diff --git a/libs/CheatEngine.Client.Abstractions/Dispatching/ICheatEngineDispatcher.cs b/libs/CheatEngine.Client.Abstractions/Dispatching/ICheatEngineDispatcher.cs index 8417ef6..b7bfda0 100644 --- a/libs/CheatEngine.Client.Abstractions/Dispatching/ICheatEngineDispatcher.cs +++ b/libs/CheatEngine.Client.Abstractions/Dispatching/ICheatEngineDispatcher.cs @@ -100,8 +100,12 @@ public void Invoke(Action callback) /// Runs a callback on the captured main thread or throws when dispatch fails. /// /// Cancellation is observed before dispatch admission only, never while a callback is running.

The four-parameter shim that existed only for a binary compatibility the 1.0 line does not need is gone; every call with three, four or five arguments binds to the remaining constructor unchanged. The default value, which a Try method leaves in its failure output on success, is now safe to read: Operation and Message return string.Empty instead of null, and the new IsDefault property tells the default value from a constructed failure, including one of kind Unknown. Throw and ToString use IsDefault, so a default failure still throws InvalidOperationException and still formats as "". The Abstractions README documents the default value and the constructor. The .editorconfig line that silenced CS8762 (added in 812675b) is removed; every other rule is untouched. The build reports no CS8762 violation with SDK 2.0.0, and no pragma, NoWarn or severity override replaces it. SdkAobScanPort gets back the owner null guard that 812675b removed together with the suppression: the SDK annotates the owner NotNullWhen(true), and the guard keeps a contract break from reaching OwnershipHandoff.Adopt, whose ArgumentNullException would otherwise escape PatternScanner.TryScan. CheatEngineFailureTests prove the single constructor and its optional parameters, the safe default value, IsDefault on a constructed Unknown failure, and the rejection of a null operation or message. --- .editorconfig | 4 -- .../PublicAPI.Unshipped.txt | 2 +- .../CheatEngine.Client.Abstractions/README.md | 5 ++ .../Results/CheatEngineFailure.cs | 68 +++++++++---------- .../Domains/SdkAobScanPort.cs | 4 +- .../Results/CheatEngineFailureTests.cs | 57 ++++++++++++++-- 6 files changed, 96 insertions(+), 44 deletions(-) diff --git a/.editorconfig b/.editorconfig index 6eda5c5..bb87cbd 100644 --- a/.editorconfig +++ b/.editorconfig @@ -319,10 +319,6 @@ dotnet_naming_style.underscore_camel_case.capitalization = camel_case # build.

[Theory] [InlineData(-1)] From 1610ad8ae6df2d9ee213cd5d7a8cbfbdd45b5245 Mon Sep 17 00:00:00 2001 From: AriusII Date: Thu, 24 Sep 2026 18:59:37 +0200 Subject: [PATCH 158/321] Add one release outcome and base for every Client lease Abstractions gains the one lease contract of the 1.x line. ICheatEngineLease (IDisposable) exposes IsReleased, LastReleaseOutcome and Release(); Release returns what happened and Dispose performs the same release, never throws and discards the outcome. LeaseReleaseKind is an int enum with explicit values: Unknown=0, Released, AlreadyReleased, PartiallyReleased, Replaced, Superseded, ExternallyRemoved, RefusedNoTarget, RefusedTargetChanged, RefusedTargetIdentityUnavailable, RefusedRuntimeChanged, CleanupUnconfirmed, CleanupUnavailable. LeaseReleaseOutcome carries the kind and the host effect, and derives exactly one of IsComplete, IsRetryable and RequiresManualRecovery from the kind. Per A9, only Unknown and CleanupUnavailable are retryable, as in the SDK. Core gets the internal SdkReleaseOutcomes, a total mapping of the three CheatEngine.SDK 2.0.0 release enums (TargetReleaseStatus, SymbolRegistrationReleaseKind, LuaRegistrationReleaseKind) where an unknown value is Unknown with an unknown effect. RefusedProcessReused is RefusedTargetChanged, UnconfirmedAfterInvocation is CleanupUnconfirmed/Started, NotInvoked is CleanupUnavailable/NotStarted and a Lua Stale release is RefusedRuntimeChanged, because its globals may remain. Worst() combines the parts of one lease: a retryable part wins so it is retried, then manual recovery, then complete kinds; host effects combine separately. HostResourceLease is the base every lease will use. It dispatches the release to the main thread through the activation dispatcher, runs one attempt at a time and never after the lease ended, and turns a fault in the derived release into CleanupUnconfirmed with an unknown effect and a refused dispatch into a retryable CleanupUnavailable. It registers with the activation registry and, when target-bound, with the target selection. A complete outcome unregisters it; a retryable or incomplete one keeps it registered, so the activation drain retries it once more and reports every incomplete outcome as one CheatEngineOperationException of the aggregated deactivation failure (Q43), with the effect CleanupUnconfirmed. CoreResourceRegistry asks such resources for that report only in the activation drain, so a target change never throws to the caller that selected the new target. Every attempt is logged as the new Lifetime event 1701 with the operation, kind and effect only. The symbol and Lua module leases move onto this base with their own lots. The Core, Abstractions, DI and Hosting READMEs document the contract and the event; ConsumedSdkSurface records the three SDK enum types. New tests: LeaseReleaseOutcomeTests, SdkReleaseOutcomesTests (totality through MappingTotality, combinator) and HostResourceLeaseTests (main thread, idempotence, non-throwing Dispose, retry, target change, aggregation, logging). --- .../ICheatEngineLease.cs | 71 +++ .../PublicAPI.Unshipped.txt | 32 ++ .../CheatEngine.Client.Abstractions/README.md | 54 ++- .../Results/LeaseReleaseKind.cs | 83 ++++ .../Results/LeaseReleaseOutcome.cs | 120 +++++ .../Infrastructure/CoreLifetime.cs | 7 +- .../Infrastructure/CoreResourceRegistry.cs | 42 +- .../Infrastructure/HostResourceLease.cs | 261 ++++++++++ .../Infrastructure/ICoreDiagnostics.cs | 20 + .../IOutcomeReportingResource.cs | 22 + .../Infrastructure/SdkReleaseOutcomes.cs | 186 +++++++ libs/CheatEngine.Client.Core/README.md | 22 + .../ClientCoreDiagnosticsLog.cs | 5 + .../LoggerCoreDiagnostics.cs | 13 + .../README.md | 2 +- libs/CheatEngine.Client.Hosting/README.md | 2 +- .../Results/LeaseReleaseOutcomeTests.cs | 118 +++++ .../Infrastructure/CoreDiagnosticsTests.cs | 5 + .../Infrastructure/HostResourceLeaseTests.cs | 459 ++++++++++++++++++ .../Infrastructure/SdkReleaseOutcomesTests.cs | 191 ++++++++ .../LoggerCoreDiagnosticsTests.cs | 8 +- .../README.md | 2 +- .../SdkContract/ConsumedSdkSurface.cs | 3 + 23 files changed, 1705 insertions(+), 23 deletions(-) create mode 100644 libs/CheatEngine.Client.Abstractions/ICheatEngineLease.cs create mode 100644 libs/CheatEngine.Client.Abstractions/Results/LeaseReleaseKind.cs create mode 100644 libs/CheatEngine.Client.Abstractions/Results/LeaseReleaseOutcome.cs create mode 100644 libs/CheatEngine.Client.Core/Infrastructure/HostResourceLease.cs create mode 100644 libs/CheatEngine.Client.Core/Infrastructure/IOutcomeReportingResource.cs create mode 100644 libs/CheatEngine.Client.Core/Infrastructure/SdkReleaseOutcomes.cs create mode 100644 tests/CheatEngine.Client.Abstractions.Tests/Results/LeaseReleaseOutcomeTests.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Infrastructure/HostResourceLeaseTests.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Infrastructure/SdkReleaseOutcomesTests.cs diff --git a/libs/CheatEngine.Client.Abstractions/ICheatEngineLease.cs b/libs/CheatEngine.Client.Abstractions/ICheatEngineLease.cs new file mode 100644 index 0000000..b476b33 --- /dev/null +++ b/libs/CheatEngine.Client.Abstractions/ICheatEngineLease.cs @@ -0,0 +1,71 @@ +using CheatEngine.Client.Results; + +namespace CheatEngine.Client; + +/// Owns one Cheat Engine resource that the Client created for the current activation. +/// +/// +/// Call-only.

RuntimeClient now composes the snapshot from these rows instead of ten hand-written calls; what it reports is unchanged. CapabilityDocumentationTests read the implementation gate and the scenarios from the catalog, and the Abstractions capability table names each capability's scenarios. ClientCapabilityCatalogTests prove that every id appears exactly once, with the planned scenarios. The public contracts state how they evolve in 1.x. Every public interface carries a Call-only or an Implementable remark: the seven Lua module, Lua operation, result mapper, codec and module interfaces that applications implement are Implementable and frozen for 1.x; all others are Call-only and may gain members in a minor release. InterfaceStabilityRemarkTests enforce the remark and keep the READMEs' list of implementable interfaces exact. The ICheatEngineClient remarks gain the normative Try/throwing, exception, cancellation and threading rules, and, per A10, say that the Context a CheatEngineClientPlugin inherits from the SDK is a raw SDK escape hatch outside the Client's guarantees. The root and facade READMEs gain "Versioning and compatibility": SemVer from 1.0.0, one version for every package, call-only interfaces and enums may grow in a minor, implementable interfaces are frozen, CECLIENT500x APIs may change in a minor, Message text is not contractual, and a new CheatEngine.SDK major means a new Client major. The root README also names the throwing forms' exceptions and the NotApplied host effect. OutcomeEnumConventionTests check every shipped public enum: int backing, explicit values, a zero value, and Unknown = 0 on a Kind, Status, State, Effect or Scope enum. OptionEnums documents the two enums whose zero is a valid choice (MemoryStringEncoding, TargetAllocationAccess). PendingCharterEnums lists today's seven violators with their owning lot and may only shrink. --- README.md | 32 ++- .../Allocations/IAllocationClient.cs | 4 + .../Allocations/ITargetMemoryLease.cs | 10 +- .../Assembly/IAssemblyClient.cs | 4 + .../Assembly/IAutoAssemblerPatchLease.cs | 4 + .../Dispatching/ICheatEngineDispatcher.cs | 4 + .../ICheatEngineClient.cs | 51 ++++- .../ICheatEngineLease.cs | 4 +- .../IDetailedSymbolRegistrationLease.cs | 10 +- .../Inspection/IInspectionClient.cs | 4 + .../Inspection/ISymbolRegistrationLease.cs | 4 + .../Lua/IDescribedLuaModule.cs | 12 +- .../Lua/ILuaClient.cs | 4 + .../Lua/ILuaExecutionContext.cs | 12 +- .../Lua/ILuaModule.cs | 4 + .../Lua/ILuaModuleLease.cs | 12 +- .../Lua/ILuaOperation.cs | 4 + .../Lua/ILuaResultMapper.cs | 12 +- .../Lua/IOwnershipAwareLuaModule.cs | 4 + .../Lua/IUnsafeLuaClient.cs | 4 + .../Memory/IMemoryBatchClient.cs | 12 +- .../Memory/IMemoryClient.cs | 4 + .../Memory/IMemoryCodec.cs | 11 +- .../Memory/IMemoryPointerWidthContext.cs | 4 + .../Memory/IMemoryReadContext.cs | 4 + .../Memory/IMemoryWriteContext.cs | 4 + .../Modules/ICheatEngineClientModule.cs | 4 + .../Processes/ILocalProcessDiagnostics.cs | 18 +- .../Processes/IProcessClient.cs | 4 + .../CheatEngine.Client.Abstractions/README.md | 29 ++- .../Runtime/ICheatEngineRuntime.cs | 4 + .../Scanning/IPatternScanOutcomeClient.cs | 14 +- .../Scanning/IPatternScanner.cs | 4 + .../Scanning/IValueScanSession.cs | 13 +- .../Scanning/IValueScanner.cs | 4 + .../Tables/ITableClient.cs | 4 + .../Domains/ClientCapabilityCatalog.cs | 107 +++++++++ .../Domains/RuntimeClient.cs | 47 ++-- libs/CheatEngine.Client.Core/README.md | 8 +- src/CheatEngine.Client/README.md | 26 +++ .../Domains/ClientCapabilityCatalogTests.cs | 100 +++++++++ .../Domains/RuntimeClientTests.cs | 30 +++ .../CapabilityDocumentationTests.cs | 77 +++++-- .../InterfaceStabilityRemarkTests.cs | 111 ++++++++++ .../OutcomeEnumConventionTests.cs | 204 ++++++++++++++++++ 45 files changed, 954 insertions(+), 92 deletions(-) create mode 100644 libs/CheatEngine.Client.Core/Domains/ClientCapabilityCatalog.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Domains/ClientCapabilityCatalogTests.cs create mode 100644 tests/CheatEngine.Client.Repository.Tests/SourcePolicy/InterfaceStabilityRemarkTests.cs create mode 100644 tests/CheatEngine.Client.Tests/Architecture/OutcomeEnumConventionTests.cs diff --git a/README.md b/README.md index 642c27a..dccfe2c 100644 --- a/README.md +++ b/README.md @@ -197,8 +197,12 @@ Services that touch Cheat Engine must preserve this activation-lifecycle contrac Cheat Engine results that are false, absent, indeterminate or malformed; no CheatEngine.SDK exception type crosses a `Try...` method.

Its tests start a sandboxed Cheat Engine, so they must never run in CI, and they must not rely on a skip: --fail-skips on turns any skip into a failure. This commit lands first, so no later commit can make CI start Cheat Engine. - ci.yml: the option array both test legs share now passes --filter-not-trait Category=LiveQualification. Debug keeps its own Category=PackageConsumption exclusion next to it. Microsoft Testing Platform with xunit.v3 honours the repeated option together with --fail-skips on, as the local gate already shows. - WorkflowContractTests collects every --filter-not-trait value instead of the first one. The new fact LiveQualificationTestsNeverRunInCi requires the exclusion in the shared array of ci.yml and in every dotnet test step of any workflow, forbids positive trait, query and uid filters there, and forbids any workflow from setting a CHEATENGINE_CLIENT_LIVE_QUALIFICATION* variable. - The local commands of CONTRIBUTING, the root README and the Client tests README add the same exclusion, so they stay green once live tests exist; the CI table and the repository tests README say so. --- .github/workflows/ci.yml | 8 ++- CONTRIBUTING.md | 17 +++--- README.md | 7 ++- .../README.md | 5 +- .../Workflows/WorkflowContractTests.cs | 56 ++++++++++++++++++- tests/CheatEngine.Client.Tests/README.md | 9 ++- 6 files changed, 84 insertions(+), 18 deletions(-) diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index a14da5c..68ff955 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -157,8 +157,9 @@ jobs: # One parallel run over every tests/**/*.Tests module.

This adds the runner as C# test code under tests/CheatEngine.Client.Tests/LiveQualification: no script, no new project, no new package (Process, PEReader, EventWaitHandle and MemoryMappedFile come from the platform) and no lock-file change. Components, all [SupportedOSPlatform("windows")]: - LiveQualificationOptIn and LiveQualificationFixture: a live fact runs only when CHEATENGINE_CLIENT_LIVE_QUALIFICATION holds the exact phrase and CHEATENGINE_CLIENT_PACKAGE_SOURCE names the packed packages, never with CI=true. Otherwise it fails at once with the local command; it is never skipped. Only an authorized run initializes the packaged feed. The run root must lie outside the repository and apart from the installation. - HostProcessGuard refuses a session while a Cheat Engine, gtutorial or DBWIN listener runs, starts the sandboxed cheatengine-x86_64.exe directly with DOTNET_*, MSBUILD*, TESTINGPLATFORM*, VSTEST* and every inherited CHEATENGINE_*, CE_SDK_LIVE_PROBE_* and CECLIENT_QUALIFICATION_* value removed, and closes then kills a session past 10 minutes. - CheatEngineInstallation verifies the source read-only (host SHA-256, file version 7.7.0.10621, AMD64 through PEReader, both gtutorial hashes), copies it to /ce, verifies the copy, and fingerprints the host executable and autorun folder before and after the run. - SandboxLayout, TargetLauncher (target identity and Q45 module screen), AuthorizationManifestWriter (ce77-live-probe-v1, at most 25 minutes, plus liveprobe.fault.json), PluginBundleBuilder (harness built from the packed packages in an isolated consumer), LuaDriverScript (createTimer state machine, pcall per step, R lines, settings toggles NotExecuted with an operator prompt until the spike proves them, address list cleared, DONE, closeCE), DebugOutputCapture and DebugOutputBuffer (managed DBWIN listener filtered on the CE process), TranscriptParser (Lua %q), ReceiptLedger (receipt/v1 JSONL, run directory redacted to , local paths and user or machine names refused) and QualificationSummaryWriter (summary/v1, verdicts derived from receipts, never inferred). - LiveSandboxSession orchestrates one session with a finally that stops Cheat Engine and the target and restores the user state. The only live fact is the S0 skeleton, LiveSandboxSpikeTests (traits Category=LiveQualification and Session=S0, serial collection). The user state guard lands in the next commit; until then the session stops before Cheat Engine starts (UnavailableUserStateGuard), so no run can touch HKCU\Software\Cheat Engine without a verified backup. The harness's QualificationAuthorization and QualificationFaultSwitch are compiled into the test project, so AuthorizationManifestTests prove the written files against the code that reads them. CI-run unit tests: LiveQualificationOptInTests, CheatEngineInstallationTests (fake files), AuthorizationManifestTests, LuaDriverScriptTests (golden text), TranscriptParserTests, ReceiptLedgerTests, QualificationSummaryWriterTests, DebugOutputBufferTests, HostProcessGuardTests and LiveSandboxSessionTests. The Client tests README gains a Live qualification section with the exact local command and the spike facts still pending; the harness README points to the runner. --- .../README.md | 10 +- .../CheatEngine.Client.Tests.csproj | 6 + .../AuthorizationManifestTests.cs | 144 +++++++++ .../AuthorizationManifestWriter.cs | 84 +++++ .../CheatEngineInstallation.cs | 240 ++++++++++++++ .../CheatEngineInstallationTests.cs | 178 ++++++++++ .../LiveQualification/CheatEngineUserState.cs | 49 +++ .../DebugOutputBufferTests.cs | 74 +++++ .../LiveQualification/DebugOutputCapture.cs | 252 +++++++++++++++ .../LiveQualification/HostProcessGuard.cs | 201 ++++++++++++ .../HostProcessGuardTests.cs | 100 ++++++ .../LiveQualificationFixture.cs | 70 ++++ .../LiveQualificationOptIn.cs | 155 +++++++++ .../LiveQualificationOptInTests.cs | 193 +++++++++++ .../LiveQualification/LiveSandboxSession.cs | 249 ++++++++++++++ .../LiveSandboxSessionTests.cs | 58 ++++ .../LiveSandboxSpikeTests.cs | 43 +++ .../LiveQualification/LuaDriverScript.cs | 272 ++++++++++++++++ .../LiveQualification/LuaDriverScriptTests.cs | 193 +++++++++++ .../LiveQualification/PluginBundleBuilder.cs | 97 ++++++ .../QualificationSummaryWriter.cs | 267 +++++++++++++++ .../QualificationSummaryWriterTests.cs | 115 +++++++ .../LiveQualification/ReceiptLedger.cs | 254 +++++++++++++++ .../LiveQualification/ReceiptLedgerTests.cs | 122 +++++++ .../LiveQualification/SandboxLayout.cs | 91 ++++++ .../LiveQualification/TargetLauncher.cs | 140 ++++++++ .../LiveQualification/TranscriptParser.cs | 305 ++++++++++++++++++ .../TranscriptParserTests.cs | 116 +++++++ tests/CheatEngine.Client.Tests/README.md | 80 +++++ 29 files changed, 4154 insertions(+), 4 deletions(-) create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/AuthorizationManifestTests.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/AuthorizationManifestWriter.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/CheatEngineInstallation.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/CheatEngineInstallationTests.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/CheatEngineUserState.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/DebugOutputBufferTests.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/DebugOutputCapture.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/HostProcessGuard.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/HostProcessGuardTests.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/LiveQualificationFixture.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/LiveQualificationOptIn.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/LiveQualificationOptInTests.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/LiveSandboxSession.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/LiveSandboxSessionTests.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/LiveSandboxSpikeTests.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/LuaDriverScript.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/LuaDriverScriptTests.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/PluginBundleBuilder.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/QualificationSummaryWriter.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/QualificationSummaryWriterTests.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/ReceiptLedger.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/ReceiptLedgerTests.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/SandboxLayout.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/TargetLauncher.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/TranscriptParser.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/TranscriptParserTests.cs diff --git a/tests/CheatEngine.Client.LivePlugin.Qualification/README.md b/tests/CheatEngine.Client.LivePlugin.Qualification/README.md index 1012d3b..9b31379 100644 --- a/tests/CheatEngine.Client.LivePlugin.Qualification/README.md +++ b/tests/CheatEngine.Client.LivePlugin.Qualification/README.md @@ -100,7 +100,9 @@ produce from this source graph: dotnet build .\tests\CheatEngine.Client.LivePlugin.Qualification\CheatEngine.Client.LivePlugin.Qualification.csproj -c Release -p:CheatEnginePluginOutputPath= ``` -A host run never uses that build: a future qualification procedure would compile the same sources again outside the -repository against the exact CI Client packages and the pinned CheatEngine.SDK 2.0.0 from nuget.org, then invoke a -CheatEngine.SDK runner.

Live facts carry `Category=LiveQualification` and a `Session=S0`..`S6` +trait and share the serial collection `Live qualification`. Both CI legs and every local gate exclude them by trait. They +are never skipped: without the opt-in they fail at once with the instructions below, and they also fail when `CI=true`. + +One session runs in this order: + +1. `HostProcessGuard` refuses to start while a `cheatengine-*`, `Cheat Engine` or `gtutorial*` process runs, or while + another debug output listener (DebugView) owns `DBWIN_BUFFER`. +2. `CheatEngineInstallation` verifies the source installation without writing to it: the SHA-256 of + `cheatengine-x86_64.exe` (`9727076D…`, the hash the harness gate pins), its file version 7.7.0.10621, its AMD64 + machine (read with `PEReader`) and the hashes of `gtutorial-x86_64.exe` (`2DABEFFD…`) and `gtutorial-i386.exe` + (`9131B1CA…`). It fingerprints the host executable and the `autorun` folder before the run and again after it. +3. `SandboxLayout` creates `/-<4 hex>/`. The Cheat Engine user state guard backs up the user + state, then the installation is copied to `/ce` and verified again. +4. `PluginBundleBuilder` compiles the harness sources in an isolated consumer outside any repository, against the + packed `CheatEngine.Client` of `CHEATENGINE_CLIENT_PACKAGE_SOURCE` and `CheatEngine.SDK` from nuget.org + (`PackagedClientFeedFixture`), and deploys the complete closure to `/plugins/`. +5. `TargetLauncher` starts the sandbox's gtutorial after checking its hash, and records its process id, start time and + modules; no `speedhack`, `allochook`, `luaclient`, `vehdebug` or `dbk` module may appear in it (Q45). +6. `AuthorizationManifestWriter` writes the `ce77-live-probe-v1` manifest: the pinned host, the target's process id and + hash, `disposable`, and an expiry at most 25 minutes ahead. The harness gate (`QualificationAuthorization`, compiled + into this project) accepts it, and it accepts nothing longer than 30 minutes. For fault scenarios the writer also + writes `liveprobe.fault.json` next to the plugin. +7. `LuaDriverScript` generates `/ce/autorun/zz_cheatengine_client_qualification.lua`: a `createTimer` state machine + on the main thread, one step per tick, each under `pcall`. It waits for the main form, opens the target, loads the + plugin, waits for the harness functions, calls them, inspects the settings form read-only, clears the address list, + writes `DONE` and calls `closeCE()`. Each step appends `Rstepok|error|notexecuted%q` to the transcript. + The plugin toggles through Settings > Plugins are recorded as `notexecuted` with an operator prompt until the spike + proves that `getSettingsForm()` can perform them. +8. `DebugOutputCapture` owns the DBWIN objects (4096-byte section, `DBWIN_BUFFER_READY` and `DBWIN_DATA_READY`) and keeps + only the Cheat Engine process's messages (`DebugOutputBuffer`). +9. `HostProcessGuard` starts `/ce/cheatengine-x86_64.exe` directly, never the launcher, with an environment + stripped of `DOTNET_*`, `MSBUILD*`, `TESTINGPLATFORM*`, `VSTEST*` and every inherited `CHEATENGINE_*`, + `CE_SDK_LIVE_PROBE_*` and `CECLIENT_QUALIFICATION_*` value. It adds only the session's `CE_SDK_LIVE_PROBE_*` and + `CECLIENT_QUALIFICATION_*` inputs and `CHEATENGINE_SDK_IDENTIFY_ON_ENABLE=1`. A session that exceeds 10 minutes is + closed, then killed, and marked `TimedOut`. A `finally` always stops Cheat Engine and the target and restores the user + state. +10. `TranscriptParser` decodes the transcript (Lua `%q` escapes). `ReceiptLedger` writes `receipts.jsonl` + (`cheatengine-client-qualification-receipt/v1`): the run directory becomes ``, and a receipt that still holds + a local path, the user name or the machine name is refused. `QualificationSummaryWriter` writes `summary.json` + (`cheatengine-client-qualification-summary/v1`): the package, SDK, host and target tuple, one verdict per scenario and + capability derived from the receipts (NotExecuted unless every check passed or one failed), and `registryRestored`. + +The only live fact so far is `LiveSandboxSpikeTests` (`Session=S0`), the spike: it loads the harness on +gtutorial-x86_64, calls `status`, `runtime` and `capabilities(1)`, inspects the settings form and closes Cheat Engine, +then requires the user state restored, the source installation unchanged and no process left. Until the user state +guard exists, the session stops before Cheat Engine starts. The facts the spike establishes are still pending and will +be recorded here: the registry values of the plugin list, whether the settings toggle is feasible, the dialogs Cheat +Engine shows, what disable does at `closeCE`, what `loadPlugin` enables, whether elevation is needed, and whether +hostfxr needs `DOTNET_ROOT` once `DOTNET_*` is removed.

Until now the runner refused every session for that reason; this commit adds the guard and lets the S0 fact use it. - RegistrySnapshot takes a recursive snapshot of a key of HKEY_CURRENT_USER (every value name, type and raw data, every subkey), writes and reads it as cheatengine-client-registry-backup/v1 JSON, and restores it: DeleteSubKeyTree, recreate, then prove the result equal to the snapshot. A value type it cannot restore exactly stops the session before anything changes. - FileTreeBackup does the same for the %APPDATA% folder: a byte copy plus a listing of every file (length, SHA-256) and folder, restored by deleting the folder, copying the backup back (or leaving it absent) and verifying the listing. - CheatEngineRegistryGuard writes /hkcu-backup.json and the %APPDATA% backup, reads the registry backup back, writes the crash marker /registry-restore-pending.json naming them, and only then neutralizes the configured plugin-list subkeys and values (none until the S0 spike names them). The restore removes the marker only after both restores are verified. A marker found when a session begins is restored first and fails that run; if the restore fails, the marker stays and the error names the backups. - CheatEngineUserStateLocations accepts only HKCU\Software\Cheat Engine with %APPDATA%\Cheat Engine, or a scratch key HKCU\Software\CheatEngine.Client.Tests\ with a temporary folder; RegistrySnapshot.Restore checks the key again before it deletes anything. - The placeholder UnavailableUserStateGuard is removed; the S0 fact uses CheatEngineRegistryGuard.ForWorkstation(). Tests run in CI on the scratch key and a temporary folder only, in a serial collection, and never open HKCU\Software\Cheat Engine: RegistrySnapshotTests (every value type round-trips, absent keys stay absent, guarded keys, the scratch key and its empty parent are deleted) and RegistryRecoveryTests (neutralized session, verified restore, restore on dispose, crash marker recovery that fails the next run, marker kept while the restore does not verify, a created %APPDATA% folder removed again). The Client tests README describes the guard. --- .../CheatEngineRegistryGuard.cs | 424 ++++++++++++++++++ .../LiveQualification/CheatEngineUserState.cs | 24 - .../LiveSandboxSpikeTests.cs | 2 +- .../RegistryRecoveryTests.cs | 174 +++++++ .../LiveQualification/RegistrySnapshot.cs | 243 ++++++++++ .../RegistrySnapshotTests.cs | 158 +++++++ .../LiveQualification/SandboxLayout.cs | 21 +- .../LiveQualification/ScratchRegistryKey.cs | 82 ++++ tests/CheatEngine.Client.Tests/README.md | 40 +- 9 files changed, 1132 insertions(+), 36 deletions(-) create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/CheatEngineRegistryGuard.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/RegistryRecoveryTests.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/RegistrySnapshot.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/RegistrySnapshotTests.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/ScratchRegistryKey.cs diff --git a/tests/CheatEngine.Client.Tests/LiveQualification/CheatEngineRegistryGuard.cs b/tests/CheatEngine.Client.Tests/LiveQualification/CheatEngineRegistryGuard.cs new file mode 100644 index 0000000..5294f98 --- /dev/null +++ b/tests/CheatEngine.Client.Tests/LiveQualification/CheatEngineRegistryGuard.cs @@ -0,0 +1,424 @@ +using System.Globalization; +using System.Runtime.Versioning; +using System.Security.Cryptography; +using System.Text; +using System.Text.Json; + +using Microsoft.Win32; + +namespace CheatEngine.Client.Tests.LiveQualification; + +/// +/// Where the Cheat Engine user state lives.

Its evidence must name that tree, so that a later change to a shipping source is visible and requires a new run, and no document may claim a qualification before evidence exists. - QualifiedSourceDigest, in the LiveQualification folder of the Client tests, is the SHA-256 of a sha256sum-style manifest over libs/**, src/**, source-generators/** and templates/** (lock files included), Directory.Build.*, Directory.Packages.props, eng/*.props and global.json, each with CRLF normalized to LF (the binary extensions of .gitattributes as they are). It excludes *.md, PublicAPI.*.txt, AnalyzerReleases.*.md and HostQualificationEvidence.cs, and skips what .gitignore excludes (bin, obj, artifacts, tool folders, binlog and user files), like the RepositoryRoot helpers. The same file is compiled into CheatEngine.Client.Repository.Tests, which keeps no project reference and starts no process. - The run summary records it as tuple.qualifiedSourceDigest. - QualifiedSourceDigestTests: CRLF and LF checkouts hash the same, the input and exclusion lists are exactly the plan's, each path is classified as the plan says, content and path changes move the digest while excluded files never do, binary files are not normalized, and git ls-files agrees: every tracked input is enumerated and no ignored file is. - QualificationEvidenceTests.NoQualificationClaimWithoutCommittedEvidence fails while the Evidence folder of the live runner holds no committed run summary and a README, the CHANGELOG, RELEASING or a capability table claims a host qualification: a CHANGELOG Qualification section, a scenario id with a Passed or Waived verdict, a live run id, a sentence stating a qualification on Cheat Engine, or a Qualification cell that reports a pass. A companion fact pins those forms against today's wording, and EveryShippingSourceIsBoundByTheDigest proves that the digest covers every shipping source the repository helpers see. Both test READMEs describe the digest and the new facts. A negated Qualification cell ("never qualified", "not passed") is no claim, and the Abstractions capability table says why UnsafeLuaExecution stays Unknown without the word "qualified". --- .../CheatEngine.Client.Abstractions/README.md | 2 +- ...CheatEngine.Client.Repository.Tests.csproj | 6 + .../QualificationEvidenceTests.cs | 228 ++++++++++++++++++ .../README.md | 8 + .../LiveQualification/LiveSandboxSession.cs | 6 +- .../QualificationSummaryWriter.cs | 3 + .../QualificationSummaryWriterTests.cs | 3 +- .../QualifiedSourceDigest.cs | 141 +++++++++++ .../QualifiedSourceDigestTests.cs | 183 ++++++++++++++ tests/CheatEngine.Client.Tests/README.md | 18 +- 10 files changed, 591 insertions(+), 7 deletions(-) create mode 100644 tests/CheatEngine.Client.Repository.Tests/Qualification/QualificationEvidenceTests.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/QualifiedSourceDigest.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/QualifiedSourceDigestTests.cs diff --git a/libs/CheatEngine.Client.Abstractions/README.md b/libs/CheatEngine.Client.Abstractions/README.md index 492b5a0..ba846d3 100644 --- a/libs/CheatEngine.Client.Abstractions/README.md +++ b/libs/CheatEngine.Client.Abstractions/README.md @@ -107,7 +107,7 @@ Each capability's qualification gate requires receipts for the live scenarios na | `Client.Inspection` | Operational adapter | Evidence from the consumed CheatEngine.SDK 2.0.0 identity | Not probed by the snapshot (`Unknown`) | Unknown until Client receipts for Q16.b and Q28 exist | `Unknown`; `Unavailable` when the package gate is `Missing` | | `Client.Tables` | Operational adapter | Evidence from the consumed CheatEngine.SDK 2.0.0 identity | Not probed by the snapshot (`Unknown`) | Unknown until Client receipts for Q34 exist | `Unknown`; `Unavailable` when the package gate is `Missing` | | `Client.ProtectedLua` | Operational adapter | Evidence from the consumed CheatEngine.SDK 2.0.0 identity | Not probed by the snapshot (`Unknown`) | Unknown until Client receipts for Q05, Q16 and Q19 exist | `Unknown`; `Unavailable` when the package gate is `Missing` | -| `Client.UnsafeLuaExecution` | Operational, policy opt-in | Evidence from the consumed CheatEngine.SDK 2.0.0 identity | Not probed by the snapshot (`Unknown`) | Never qualified: arbitrary Lua has no scenario, so it stays `Unknown` | `Unavailable` without `EnableUnsafeLuaExecution()`; otherwise `Unknown` | +| `Client.UnsafeLuaExecution` | Operational, policy opt-in | Evidence from the consumed CheatEngine.SDK 2.0.0 identity | Not probed by the snapshot (`Unknown`) | Stays `Unknown`: no scenario covers arbitrary Lua | `Unavailable` without `EnableUnsafeLuaExecution()`; otherwise `Unknown` | | `Client.Allocations` | Contract-only (Unavailable) | Evidence from the consumed CheatEngine.SDK 2.0.0 identity | Not probed by the snapshot (`Unknown`) | Unknown until Client receipts for Q30.a exist | `Unavailable` | | `Client.Assembly` | Contract-only (Unavailable) | Evidence from the consumed CheatEngine.SDK 2.0.0 identity | Not probed by the snapshot (`Unknown`) | Unknown until Client receipts for Q32 exist | `Unavailable` | diff --git a/tests/CheatEngine.Client.Repository.Tests/CheatEngine.Client.Repository.Tests.csproj b/tests/CheatEngine.Client.Repository.Tests/CheatEngine.Client.Repository.Tests.csproj index 43c9bdb..19ef643 100644 --- a/tests/CheatEngine.Client.Repository.Tests/CheatEngine.Client.Repository.Tests.csproj +++ b/tests/CheatEngine.Client.Repository.Tests/CheatEngine.Client.Repository.Tests.csproj @@ -14,4 +14,10 @@ + + + + + diff --git a/tests/CheatEngine.Client.Repository.Tests/Qualification/QualificationEvidenceTests.cs b/tests/CheatEngine.Client.Repository.Tests/Qualification/QualificationEvidenceTests.cs new file mode 100644 index 0000000..3d153e2 --- /dev/null +++ b/tests/CheatEngine.Client.Repository.Tests/Qualification/QualificationEvidenceTests.cs @@ -0,0 +1,228 @@ +using System.Text.Json; +using System.Text.RegularExpressions; + +using CheatEngine.Client.Repository.Tests.Infrastructure; +using CheatEngine.Client.Tests.LiveQualification; + +namespace CheatEngine.Client.Repository.Tests.Qualification; + +/// +/// Evidence discipline for the live qualification (audit ch.22: an unexecuted test stays unexecuted).

Extensions.DependencyInjection and Hosting use Core and DI internals through InternalsVisibleTo, and Core has no public API, so a graph that mixed Client versions could fail at run time with MissingMethodException or TypeLoadException that neither package validation nor the public API baselines can see. The 1.0.0 nuspecs are immutable once pushed, so the edges become exact now (audit PKG-10, API-15). CheatEngineClientPinInterClientDependencies runs after the internal _GetProjectReferenceVersions target of the .NET SDK 10.0.401 pack targets and before GenerateNuspec. It rewrites the ProjectVersion metadata of the _ProjectReferencesWithVersions items, which PackTask parses as a version range, to [$(PackageVersion)], and refuses with CHEATENGINECLIENT9019 a reference packed as another version. It acts only when a nuspec is generated: restore never runs it, the locked restore passes and no lock file changes. The CheatEngine.SDK dependency stays [2.0.0, 3.0.0). The eng/CheatEngineSdk.props checklist for a .NET SDK bump now names the item and metadata the target depends on. InterClientDependenciesRequireTheCoPackedVersion becomes InterClientDependenciesRequireTheExactCoPackedVersion: it freezes the seven Client edges of the delivery graph, package by package, and requires [X.Y.Z] on each. The facade, root and Core READMEs state the lockstep contract: one version for the seven packages, exact inter-Client dependencies, and Core as a dependency of Extensions.DependencyInjection rather than a standalone package. --- Directory.Build.targets | 35 +++++++++++++++++++ README.md | 8 +++++ eng/CheatEngineSdk.props | 8 +++-- libs/CheatEngine.Client.Core/README.md | 8 +++++ src/CheatEngine.Client/README.md | 8 +++++ .../Packaging/PackageConsumptionSmokeTests.cs | 34 +++++++++++++----- tests/CheatEngine.Client.Tests/README.md | 5 +-- 7 files changed, 92 insertions(+), 14 deletions(-) diff --git a/Directory.Build.targets b/Directory.Build.targets index dbf6c2a..92cf062 100644 --- a/Directory.Build.targets +++ b/Directory.Build.targets @@ -189,6 +189,41 @@ Text="$(MSBuildProjectName) would be packed as '$(PackageVersion)', but MinVer computed '$(MinVerVersion)'.

The gate now follows the range: it is Satisfied when the SemVer part of the loaded CheatEngine.SDK.Engine informational version (build metadata ignored) has the supported major and is at or above the pin by SemVer precedence, so 2.0.0-rc.1 is below 2.0.0. Another major or a version below the pin is Missing; a missing or malformed informational version, or a build without an embedded identity, is Unknown. The supported major reaches Core from eng/CheatEngineSdk.props at build, as the CheatEngine.Client.ConsumedSdk.SupportedMajor assembly metadata; the floor is the embedded consumed version, which CHEATENGINECLIENT9050 already proves equal to the pin. The source holds no version literal. A small private SemVer 2.0.0 parser and comparer does the precedence (numeric identifiers numerically, a release above its prereleases). The reason says whether the loaded assembly is exactly the reviewed package or another release of the supported major, and the new internal ExactReviewedIdentity keeps that distinction for the qualification gate of L24. Hosting's activation event 20 gains a version-only identity label (the reviewed package, another release of 2.x at or above 2.0.0, outside that range, or not compared) next to the package evidence state. ConsumedSdkIdentityTests and a RuntimeClientTests theory pin the matrix: 2.0.0+325c47b... Satisfied and exact; 2.0.1 and 2.1.0-beta.1 Satisfied, not exact; 2.0.0-rc.1, 1.0.0 and 3.0.0 Missing; an absent version Unknown. They also cover the SemVer precedence chain, malformed versions, a missing or inconsistent supported major, and the identity of the build under test. The embedding test expects the new metadata, and CheatEngineClientPluginTests checks the label in the path-free event 20. The Abstractions capability table, the Core and Hosting READMEs and the migration checklist describe the new rule. --- eng/CheatEngineSdk.props | 3 +- .../CheatEngine.Client.Abstractions/README.md | 35 +- .../CheatEngine.Client.Core.csproj | 4 + .../Infrastructure/ConsumedSdkIdentity.cs | 304 ++++++++++++++++-- libs/CheatEngine.Client.Core/README.md | 10 +- .../CheatEngineClientPlugin.cs | 7 +- .../ClientHostingLog.cs | 10 +- libs/CheatEngine.Client.Hosting/README.md | 9 +- .../Domains/RuntimeClientTests.cs | 94 +++--- .../ConsumedSdkIdentityTests.cs | 164 ++++++++++ tests/CheatEngine.Client.Core.Tests/README.md | 7 +- .../CheatEngineClientPluginTests.cs | 5 + .../ConsumedSdkIdentityEmbeddingTests.cs | 9 +- 13 files changed, 562 insertions(+), 99 deletions(-) create mode 100644 tests/CheatEngine.Client.Core.Tests/Infrastructure/ConsumedSdkIdentityTests.cs diff --git a/eng/CheatEngineSdk.props b/eng/CheatEngineSdk.props index b09d952..c1ab5dc 100644 --- a/eng/CheatEngineSdk.props +++ b/eng/CheatEngineSdk.props @@ -35,7 +35,8 @@ - the CheatEngine.SDK default of the template content project and its "Keep CheatEngine.SDK on N.x" comment (templates/CheatEngine.Client.Templates/content/CheatEngine.Plugin/CheatEngine.Plugin.csproj); - the identity literals of PackagedClientFeedFixture.PinnedSdkIdentity and LockFileTests, and the sample identity - of tests/CheatEngine.Client.Core.Tests/Domains/RuntimeClientTests.cs; the retired literals join + and version matrix of tests/CheatEngine.Client.Core.Tests/Domains/RuntimeClientTests.cs and + tests/CheatEngine.Client.Core.Tests/Infrastructure/ConsumedSdkIdentityTests.cs; the retired literals join SdkPinTests.RetiredSdkIdentityLiteralsAppearNowhere; - the NuGet content hash, bridge SHA-256 and source commit lines of the three install guides; - the CheatEngine.SDK major ignored by .github/dependabot.yml (DependabotConfigurationTests) and the Client, SDK and diff --git a/libs/CheatEngine.Client.Abstractions/README.md b/libs/CheatEngine.Client.Abstractions/README.md index ba846d3..28760d1 100644 --- a/libs/CheatEngine.Client.Abstractions/README.md +++ b/libs/CheatEngine.Client.Abstractions/README.md @@ -90,26 +90,29 @@ deterministic priority.

Its production SdkRuntimeObservationPort calls only read-only CheatEngine.SDK 2.0.0 operations: RuntimeObservations.TryObserveRuntimeInfo, RuntimeHostOperations (ObserveHost, TryGetCheatEngineFileVersion, TryGetSystemArchitecture, TryIsCheatEngine64Bit, TryGetOperatingSystem) and RuntimeProcessOperations (ObserveCurrent, ObserveTargetArchitecture, TryGetConfiguredPointerSize). The SDK now brackets the selected PID, derives the ISA and reports every outcome as a status, so the Client no longer does any of it: the eight ADR-01 bindings getOpenedProcessID, getCEVersion, getSystemArchitecture, getABI, targetIs64Bit, targetIsX86, targetIsArm and getPointerSize are deleted, with LuaRuntimeProbe, IRuntimeProbe, ITargetArchitectureProbe, ProbeClassifier and its "indistinguishable Lua failure" limitation, and ProbeResult. RuntimeObservationMapping maps every ProcessOperationStatusKind, LuaOperationStatusKind and RuntimeCapabilityAvailabilityState value explicitly and fails closed on an unknown one. A status that establishes no target keeps its own failure kind: TargetNotAttached, TargetChanged, TargetIdentityUnavailable for a file opened as a process, CapabilityUnavailable, LuaError, InvalidHostResult, OperationRejected for an unconfirmed selection, and IndeterminateHostResult for Unknown. IProcessClient reports them with a Completed host effect instead of the former IndeterminateHostResult, and a file opened as a process now invalidates the known selection. TargetArchitectureObserver is the one target observation policy of the Runtime, Processes and Memory domains. It uses ObserveTargetArchitecture and, when one target fact raises or is malformed, narrows to ObserveCurrent, TryGetConfiguredPointerSize and ObserveCurrent again: the PID, bitness and configured size are kept only when both PID reads agree, and the ISA, backend and ABI stay unknown. RuntimeObserver uses the SDK snapshot first; without one (file as process, target change, raising or malformed global) it reads the host facts together, then one by one, and observes the target through the same policy. The ProcessSelection host gate now comes from the SDK's own Process.Current capability entry, or from the target observation's status when the SDK produced no snapshot (Missing, Faulted, Malformed or Unknown); the catalog's host source is renamed SdkSelectedProcess. The runtime snapshot reports the SDK's capability list. Because getCEVersion is gone, the typed version planned for the snapshot reshape moves here: CheatEngineRuntimeVersionInfo carries the complete CheatEngineVersion? instead of the coarse double, and IsOnQualifiedCheatEngineLine compares major and minor as integers. IMemoryCodecContextPort observes targets through the same port, and PointerWidthPolicy is fed by the SDK's ConfiguredPointerSizeDiffersFromBitness; no width ever comes from the plugin process (CESDK1020). An unobservable width keeps the kind of the SDK status. AttachExactName reports a cancellation before the local catalog through CancellationMapping (NotStarted). Ratchets: FrozenLuaGlobals loses the eight entries, FrozenLuaUsage the five generated-code symbols only they used, and RuntimeProbeCallsOnlyReadOnlyGlobals becomes RuntimeProbeCallsOnlyReadOnlySdkOperations: an exact, non-empty allowlist for the port, no runtime operation outside it, and no CheatTableFiles or mutating binding from an observation-only type (Q45). ConsumedSdkSurface and SdkApiUsage are regenerated from the failing test's output. sonar.yml excludes SdkRuntimeObservationPort.cs from coverage, like the other SDK ports. Tests: observer policy and mapping totality, SDK port admission, RuntimeClient and ProcessClient over a status-driven fake port, a TryContractTests case for the process and runtime family, and the memory fakes moved to the target observation port. --- .github/workflows/sonar.yml | 2 +- .../Processes/IProcessClient.cs | 47 +- .../PublicAPI.Unshipped.txt | 7 +- .../CheatEngine.Client.Abstractions/README.md | 29 +- .../Runtime/CheatEngineRuntimeSnapshot.cs | 22 +- .../Runtime/CheatEngineRuntimeVersionInfo.cs | 38 +- .../Domains/ClientCapabilityCatalog.cs | 9 +- .../Domains/IMemoryCodecContextPort.cs | 38 +- .../Domains/IProcessHost.cs | 9 +- .../Domains/IRuntimeObservationPort.cs | 44 + .../Domains/IRuntimeProbe.cs | 18 - .../Domains/ITargetArchitectureProbe.cs | 37 - .../Domains/ITargetObservationPort.cs | 40 + .../Domains/LocalProcessHost.cs | 29 +- .../Domains/LuaRuntimeProbe.cs | 47 - .../Domains/MemoryClient.cs | 108 +- .../Domains/PointerWidthPolicy.cs | 28 +- .../Domains/ProbeClassifier.cs | 59 -- .../Domains/ProbeResult.cs | 56 - .../Domains/ProcessClient.cs | 105 +- .../Domains/RuntimeClient.cs | 108 +- .../Domains/RuntimeObservationMapping.cs | 179 ++++ .../Domains/RuntimeObserver.cs | 126 +++ .../Domains/SdkRuntimeObservationPort.cs | 78 ++ .../Domains/TargetArchitectureObserver.cs | 303 ++---- .../Infrastructure/ClientLuaGlobals.cs | 41 - libs/CheatEngine.Client.Core/README.md | 59 +- ...EngineClientServiceCollectionExtensions.cs | 1 + .../CheatEngineRuntimeSnapshotTests.cs | 71 +- .../Domains/ClientCapabilityCatalogTests.cs | 4 +- .../Domains/LocalProcessDiagnosticsTests.cs | 25 - .../Domains/LocalProcessHostTests.cs | 22 - .../Domains/LuaRuntimeProbeTests.cs | 48 - ...lientResourceLimitsAndBatchOutcomeTests.cs | 27 +- .../Domains/MemoryClientTests.cs | 27 +- .../MemoryCodecContextLifetimeTests.cs | 43 +- .../Domains/MemoryPointerWidthTests.cs | 151 ++- .../Domains/ProcessClientTests.cs | 320 +++--- .../Domains/RuntimeClientTests.cs | 957 +++++------------- .../Domains/RuntimeObservationMappingTests.cs | 127 +++ .../Domains/SdkRuntimeObservationPortTests.cs | 58 ++ .../TargetArchitectureObserverTests.cs | 288 +++--- .../Infrastructure/CoreDiagnosticsTests.cs | 75 +- .../Infrastructure/TryContractTests.cs | 90 +- .../SdkContract/SdkMappingContractTests.cs | 26 +- .../TestSupport/FakeRuntimeObservationPort.cs | 212 ++++ .../TestSupport/TargetObservationDouble.cs | 165 +++ .../Architecture/ArchitectureRatchetTests.cs | 31 +- .../Architecture/CapabilityRatchetTests.cs | 160 ++- .../SdkContract/ConsumedSdkSurface.cs | 68 +- .../SdkContract/SdkApiUsage.cs | 61 +- 51 files changed, 2441 insertions(+), 2282 deletions(-) create mode 100644 libs/CheatEngine.Client.Core/Domains/IRuntimeObservationPort.cs delete mode 100644 libs/CheatEngine.Client.Core/Domains/IRuntimeProbe.cs delete mode 100644 libs/CheatEngine.Client.Core/Domains/ITargetArchitectureProbe.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/ITargetObservationPort.cs delete mode 100644 libs/CheatEngine.Client.Core/Domains/LuaRuntimeProbe.cs delete mode 100644 libs/CheatEngine.Client.Core/Domains/ProbeClassifier.cs delete mode 100644 libs/CheatEngine.Client.Core/Domains/ProbeResult.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/RuntimeObservationMapping.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/RuntimeObserver.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/SdkRuntimeObservationPort.cs delete mode 100644 tests/CheatEngine.Client.Core.Tests/Domains/LuaRuntimeProbeTests.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Domains/RuntimeObservationMappingTests.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Domains/SdkRuntimeObservationPortTests.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/TestSupport/FakeRuntimeObservationPort.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/TestSupport/TargetObservationDouble.cs diff --git a/.github/workflows/sonar.yml b/.github/workflows/sonar.yml index eb430e7..1d83fbd 100644 --- a/.github/workflows/sonar.yml +++ b/.github/workflows/sonar.yml @@ -183,7 +183,7 @@ jobs: # (xUnit has no attached Cheat Engine process or Lua state): its lines are untestable, not merely # untested, and its non-SDK branches keep the tests they allow next to it (for example # SdkTableRecordMutationPortTests).

Subject: [PATCH 169/321] Attach through SelectAndObserve and track incarnations ProcessClient.TryAttach now selects the process through RuntimeProcessOperations.SelectAndObserve, behind the new internal IProcessSelectionPort and its production SdkProcessSelectionPort: the SDK calls openProcess and reads the selected PID again, so a normal return of openProcess is no longer taken as success. Every status maps explicitly, with an Unknown host effect because what Cheat Engine now selects is unknown: SelectionNotConfirmed is OperationRejected, TargetNotAttached stays TargetNotAttached, FileAsProcessTarget is TargetIdentityUnavailable, TargetChanged stays TargetChanged, and GlobalUnavailable, ProtectedLuaFailure, InvalidResult and Unknown are CapabilityUnavailable, LuaError, InvalidHostResult and IndeterminateHostResult. After a refusal the selection is observed again, so the selection epoch follows whatever Cheat Engine selected. The openProcess binding, IProcessHost.OpenProcess and the ratchet's OpenProcess assertion are deleted. The observation port gains TargetSelection.ObserveCurrent and ValidateCurrent, copied into internal TargetSelectionFacts and TargetIdentityFacts because the SDK types have internal constructors. For a local process the selection identity is now the PID and its incarnation (the creation time the SDK observed with the local backend). A known incarnation is checked with ValidateCurrent: the epoch advances when the PID changes or when the same PID denotes another incarnation (ProcessReused), as well as on a known backend, ISA or width change. An incarnation that cannot be read keeps the epoch and the last known one; a selection that moved between the target facts and the identity read is TargetChanged. A CEServer target or a target whose backend is not established gets neither an incarnation read nor local operating-system metadata (audit A12-05). The docs state the SDK's A-B-A limit: a selection that changed and changed back between two observations is not seen. RuntimeObservationMapping maps every TargetSelectionObservationStatus and TargetIdentityCheckKind value; a failed or empty observation is never evidence of a change. Ratchets: FrozenLuaGlobals loses openProcess and FrozenLuaUsage the Int64Marshaller.Push only it used. The read-only allowlist of RuntimeProbeCallsOnlyReadOnlySdkOperations gains the two TargetSelection reads, and only SdkProcessSelectionPort may reference SelectAndObserve; the new SelectAndObserveIsReachableOnlyFromTryAttach proves that ProcessClient.TryAttach is the port's only caller. ConsumedSdkSurface and SdkApiUsage are regenerated, and sonar.yml excludes SdkProcessSelectionPort.cs from coverage. Tests: every refused attach status, the epoch following a refused attach, incarnation reuse at an equal PID, unavailable identity reads, selection moves between reads, no local enrichment for CEServer and unknown backends, and mapping totality for the two selection enums. --- .github/workflows/sonar.yml | 2 +- .../Processes/IProcessClient.cs | 36 ++- .../CheatEngine.Client.Abstractions/README.md | 10 +- .../Domains/IProcessHost.cs | 11 +- .../Domains/IProcessSelectionPort.cs | 24 ++ .../Domains/IRuntimeObservationPort.cs | 19 +- .../Domains/LocalProcessHost.cs | 12 +- .../Domains/ProcessClient.cs | 279 +++++++++++----- .../Domains/RuntimeObservationMapping.cs | 90 +++++- .../Domains/SdkProcessSelectionPort.cs | 30 ++ .../Domains/SdkRuntimeObservationPort.cs | 22 +- .../Domains/TargetSelectionFacts.cs | 25 ++ .../Infrastructure/ClientLuaGlobals.cs | 3 - libs/CheatEngine.Client.Core/README.md | 31 +- ...EngineClientServiceCollectionExtensions.cs | 1 + .../Domains/LocalProcessDiagnosticsTests.cs | 5 - .../Domains/ProcessClientTests.cs | 300 +++++++++++++++--- .../Domains/RuntimeClientTests.cs | 18 +- .../Domains/RuntimeObservationMappingTests.cs | 52 +++ .../Domains/SdkRuntimeObservationPortTests.cs | 18 +- .../Infrastructure/CoreDiagnosticsTests.cs | 7 +- .../Infrastructure/TryContractTests.cs | 26 +- .../TestSupport/FakeRuntimeObservationPort.cs | 152 ++++++++- .../TestSupport/TargetObservationDouble.cs | 22 ++ .../Architecture/ArchitectureRatchetTests.cs | 5 - .../Architecture/CapabilityRatchetTests.cs | 84 ++++- .../SdkContract/ConsumedSdkSurface.cs | 18 +- .../SdkContract/SdkApiUsage.cs | 16 +- 28 files changed, 1090 insertions(+), 228 deletions(-) create mode 100644 libs/CheatEngine.Client.Core/Domains/IProcessSelectionPort.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/SdkProcessSelectionPort.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/TargetSelectionFacts.cs diff --git a/.github/workflows/sonar.yml b/.github/workflows/sonar.yml index 1d83fbd..5e3c878 100644 --- a/.github/workflows/sonar.yml +++ b/.github/workflows/sonar.yml @@ -183,7 +183,7 @@ jobs: # (xUnit has no attached Cheat Engine process or Lua state): its lines are untestable, not merely # untested, and its non-SDK branches keep the tests they allow next to it (for example # SdkTableRecordMutationPortTests).

9aefca111dc9137432d1f47d49d3bc886944cf6c Mon Sep 17 00:00:00 2001 From: AriusII Date: Thu, 24 Sep 2026 20:59:56 +0200 Subject: [PATCH 170/321] Reshape runtime and process snapshots around bitness The public runtime and process types now carry the facts the SDK 2.0 observations established, each stored as observed. ProcessSnapshot has one constructor: id, name, executablePath, the TargetBackend, the CheatEngineArchitecture, the PointerSize bitness, the raw configured pointer size, the UTC start time and the selection epoch. It never derives a width: a known architecture and bitness must agree, and local metadata or a start time is refused for any backend other than a local process. ConfiguredPointerSize and ConfiguredPointerSizeDiffersFromBitness are computed. ProcessClient fills the start time from the tracked incarnation and the configured size from the current observation only. CheatEngineRuntimeSnapshot is grouped into Version, Platform, Capabilities and Lua (A8), and loses its flattened properties and the SDK RuntimeCapabilities member. CheatEngineRuntimeVersionInfo gains SdkPackageVersion and IsReviewedSdkPackage from the consumed-SDK identity; the typed version and the integer line comparison came with the first commit of this lot. CheatEngineRuntimePlatformInfo has one constructor: HostOperatingSystem, IsCheatEngine64Bit, SystemArchitecture, TargetBackend, TargetArchitecture, TargetBitness, TargetAbi, TargetIsAndroid and ConfiguredPointerSizeBytes, with ConfiguredPointerSize and ConfiguredPointerSizeDiffersFromBitness computed. The new CheatEngineRuntimeLuaInfo reports the SDK's sticky ExternalStateResetDetected fact, read through a new SdkBoundary property so LuaRuntime keeps its single owner; its classification is unchanged. The Hosting log warning for that fact stays with the Hosting lot. ICheatEngineRuntime loses Get/TryGetSdkCapability: the SDK capability list only feeds the ProcessSelection host gate, and a capability the SDK does not probe stays Unknown. ILocalProcessDiagnostics folds into IProcessClient.TryGetLocalProcesses and GetLocalProcesses, an offline catalog read that needs no activation and reports a cancellation through CancellationMapping (NotStarted); DI no longer registers it. ClientCapabilityAvailability keeps only the evidence constructor and refuses default evidence; the legacy constructor, CreateLegacyEvidence and [StructLayout] go. ClientCapabilityAvailabilityState, ClientCapabilityEvidenceState and ClientCapabilityEvidenceReasonCode are int-backed, and the reason code gains Unknown = 0 for default evidence, so they leave PendingCharterEnums. ApprovedSdkClientTypes drops RuntimeCapabilityAvailability and RuntimeCapabilityId and adds TargetBackend and CheatEngineOperatingSystem; the RuntimeCapabilities "shipped debt" exemptions of SdkConsumerContractTests and PublicClientSignatureBoundaryTests are deleted. ConsumedSdkSurface and SdkApiUsage are regenerated, and PublicAPI.Unshipped follows RS0016 and RS0017. The qualification harness and the coexistence fixture get the minimal renames; the READMEs describe the grouped snapshot, the bitness facts and the local process catalog. --- README.md | 5 +- .../Processes/ILocalProcessDiagnostics.cs | 30 -- .../Processes/IProcessClient.cs | 18 + .../Processes/ProcessSnapshot.cs | 161 ++++--- .../PublicAPI.Unshipped.txt | 75 ++-- .../CheatEngine.Client.Abstractions/README.md | 38 +- .../Runtime/CheatEngineRuntimeLuaInfo.cs | 27 ++ .../Runtime/CheatEngineRuntimePlatformInfo.cs | 122 ++++-- .../Runtime/CheatEngineRuntimeSnapshot.cs | 93 ++--- .../Runtime/CheatEngineRuntimeVersionInfo.cs | 48 ++- .../Runtime/ClientCapabilityAvailability.cs | 49 +-- .../ClientCapabilityAvailabilityState.cs | 2 +- .../Runtime/ClientCapabilityEvidence.cs | 18 +- .../ClientCapabilityEvidenceReasonCode.cs | 17 +- .../Runtime/ClientCapabilityEvidenceState.cs | 2 +- .../Runtime/ICheatEngineRuntime.cs | 13 - .../Domains/IRuntimeObservationPort.cs | 9 + ...sDiagnostics.cs => LocalProcessCatalog.cs} | 46 +- .../Domains/ProcessClient.cs | 47 ++- .../Domains/RuntimeClient.cs | 68 +-- .../Domains/RuntimeObserver.cs | 14 +- .../Domains/SdkRuntimeObservationPort.cs | 3 + .../Domains/TargetArchitectureObserver.cs | 3 + .../Infrastructure/SdkBoundary.cs | 6 + ...EngineClientServiceCollectionExtensions.cs | 2 - .../ApprovedSdkClientTypes.cs | 4 +- .../Processes/ProcessSnapshotTests.cs | 158 +++++-- .../CheatEngineRuntimeSnapshotTests.cs | 392 ++++++++---------- .../Runtime/ClientCapabilitiesTests.cs | 48 ++- .../Runtime/ClientCapabilityEvidenceTests.cs | 46 +- .../Domains/LocalProcessDiagnosticsTests.cs | 143 ------- .../ProcessClientLocalProcessesTests.cs | 189 +++++++++ .../Domains/ProcessClientTests.cs | 69 ++- .../Domains/RuntimeClientTests.cs | 214 ++++++---- .../Domains/SdkRuntimeObservationPortTests.cs | 7 + .../Infrastructure/TryContractTests.cs | 2 + .../TestSupport/FakeRuntimeObservationPort.cs | 7 + ...eClientServiceCollectionExtensionsTests.cs | 2 +- .../CoexistenceDiagnostics.cs | 2 +- .../QualificationScenarios.cs | 10 +- .../OutcomeEnumConventionTests.cs | 3 - .../PublicClientSignatureBoundaryTests.cs | 19 +- .../SdkContract/ConsumedSdkSurface.cs | 14 +- .../SdkContract/SdkApiUsage.cs | 10 +- .../SdkContract/SdkConsumerContractTests.cs | 5 +- 45 files changed, 1270 insertions(+), 990 deletions(-) delete mode 100644 libs/CheatEngine.Client.Abstractions/Processes/ILocalProcessDiagnostics.cs create mode 100644 libs/CheatEngine.Client.Abstractions/Runtime/CheatEngineRuntimeLuaInfo.cs rename libs/CheatEngine.Client.Core/Domains/{LocalProcessDiagnostics.cs => LocalProcessCatalog.cs} (66%) delete mode 100644 tests/CheatEngine.Client.Core.Tests/Domains/LocalProcessDiagnosticsTests.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Domains/ProcessClientLocalProcessesTests.cs diff --git a/README.md b/README.md index 9f0f9d1..f0b0b01 100644 --- a/README.md +++ b/README.md @@ -187,8 +187,9 @@ All Client operations are synchronous.

None on a failed call and any undefined value are IndeterminateHostResult with an Unknown effect, never a success. Primitives, batches, bytes, strings, pointer chains and codec contexts all use it; a codec that fails after a refused context access keeps the mapped kind with an Unknown effect, since it may have made earlier accesses. Messages name the category, never an address or a value. Every pointer access goes through the width-qualified TargetMemory.TryReadPointer and TryWritePointer overloads with the bitness observed through the L9 observation port, never a width taken from the plugin process (CESDK1020). PointerSize-typed port members replace the Address branch of the scalar port, whose other types are now unreachable. PointerWidthAdmission refuses an unknown bitness on every pointer path (primitives, batches, chains, the built-in Address codec): InvalidState for a selected target without a bitness, otherwise the kind of the SDK status such as TargetNotAttached, always NotStarted. The refusal message moved to PointerWidthPolicy so the codec context and the Core paths share it; the codec context therefore reports a selected target without a bitness as InvalidState instead of IndeterminateHostResult. A target observation that faults before the first element of an Address batch no longer reports index 0 as failed. PointerValueExceedsTargetWidth is OperationRejected. It is NotStarted for a write, which the SDK refuses before calling Cheat Engine, as the plan's table states; for a read the SDK refuses a value Cheat Engine has already returned, so the effect is Completed rather than the table's NotStarted. A pointer chain reports the failing hop as "hop N of M" in its message. The manual isThirtyTwoBit checks are gone, but the chain still refuses a base address, or an address it computes by adding an offset, above 4 GiB on a 32-bit target: the SDK overload qualifies only the pointer values it reads, and a 32-bit process would wrap such an address. A computed address refused after its reads returned is now Completed instead of Started, since a read leaves no effect in the target. ConsumedSdkSurface and SdkApiUsage follow the failing inventory test: the two width-qualified overloads, PointerSize.Bit32 and its inequality operator replace the width-less pointer overloads. The Abstractions README gains the MemoryAccessFailure table and the new memory row of the Try/cancellation table; the Core README describes the route. Tests: MemoryAccessFailure totality and an end-to-end byte read and write for every value, asserted on kinds and effects; an unknown bitness refused on six pointer paths; an Address above 4 GiB refused on an x86 write (OperationRejected, NotStarted) and round-tripped on x64; a chain naming the hop whose pointer is too wide and refusing a base address above 4 GiB; an Address batch stopping at the first value too wide; and the pointer chain added to the SDK-fault Try cases. --- .../CheatEngine.Client.Abstractions/README.md | 33 +- .../Domains/IMemoryCodecContextPort.cs | 139 ++++---- .../Domains/MemoryAccessFailureMapping.cs | 131 +++++++ .../Domains/MemoryClient.cs | 323 +++++++++++------- .../Domains/PointerWidthPolicy.cs | 88 ++++- libs/CheatEngine.Client.Core/README.md | 19 +- ...lientResourceLimitsAndBatchOutcomeTests.cs | 21 +- .../Domains/MemoryClientTests.cs | 9 +- .../MemoryCodecContextLifetimeTests.cs | 9 +- .../Domains/MemoryPointerWidthTests.cs | 278 +++++++++++++-- .../Infrastructure/CoreDiagnosticsTests.cs | 32 +- .../Infrastructure/TryContractTests.cs | 31 +- .../SdkContract/SdkMappingContractTests.cs | 82 ++++- .../SdkContract/ConsumedSdkSurface.cs | 6 +- .../SdkContract/SdkApiUsage.cs | 5 +- 15 files changed, 924 insertions(+), 282 deletions(-) create mode 100644 libs/CheatEngine.Client.Core/Domains/MemoryAccessFailureMapping.cs diff --git a/libs/CheatEngine.Client.Abstractions/README.md b/libs/CheatEngine.Client.Abstractions/README.md index 19fd3fe..d401fa9 100644 --- a/libs/CheatEngine.Client.Abstractions/README.md +++ b/libs/CheatEngine.Client.Abstractions/README.md @@ -210,11 +210,16 @@ groups them in `Version`, `Platform`, `Capabilities` and `Lua` and keeps separat - **External Lua state reset** (`CheatEngineRuntimeLuaInfo.ExternalStateResetDetected`): CheatEngine.SDK detected that Cheat Engine replaced its Lua state outside the plugin's control; Lua work is then refused with `RuntimeChanged`. -Cheat Engine's pointer read follows the process width, not the configured size.

IMemoryClient gains ReadBytesDetailed, which returns the new MemoryBytesReadOutcome: Bytes is the contiguous prefix the SDK verified, with RequestedLength, ConfirmedLength, IsComplete, IsSuccess and Failure. A PartialRead is MemoryReadFailed and names the confirmed length in its message; any other failure keeps its mapped kind, and a verified prefix the SDK copied before a malformed element is kept too. A budget refusal, a dispatch failure or an SDK fault has an empty prefix, and a count outside the requested range is never published. A partial copy is therefore never confused with a host failure that copied nothing (audit AUD-08). Like a Try method, the detailed read reports refusals, host failures and cancellation in its outcome. TryReadBytes and ReadBytes are built on the same path and still publish all or nothing. A codec context read that does not fill its buffer returns false, clears the buffer so no prefix passes for data, and reports the PartialRead count in the codec's failure message. ConsumedSdkSurface and SdkApiUsage swap the two TryReadBytes overloads, PublicAPI.Unshipped gains the outcome and the method, and the Abstractions README describes the detailed read in the failure table and in the memory row of the Try/cancellation table. The Fluent test double implements the new member. Tests: a partial read reporting its prefix while the Try form publishes nothing, a malformed result keeping its verified prefix, a complete read, a budget refusal with an empty prefix, a codec context partial read, the outcome's constructor rules, the confirmed prefix in the end-to-end mapping test, and TryContractTests reaching the counted read in the static binding case plus the family and budget cases. --- .../Memory/IMemoryClient.cs | 12 ++ .../Memory/MemoryBytesReadOutcome.cs | 84 ++++++++++ .../PublicAPI.Unshipped.txt | 9 ++ .../CheatEngine.Client.Abstractions/README.md | 11 +- .../Domains/IMemoryCodecContextPort.cs | 12 +- .../Domains/MemoryAccessFailureMapping.cs | 20 +++ .../Domains/MemoryClient.cs | 88 ++++++++--- ...emoryResourceLimitsAndBatchOutcomeTests.cs | 30 ++++ ...lientResourceLimitsAndBatchOutcomeTests.cs | 4 +- .../Domains/MemoryClientTests.cs | 145 +++++++++++++++++- .../MemoryCodecContextLifetimeTests.cs | 4 +- .../Domains/MemoryPointerWidthTests.cs | 4 +- .../Infrastructure/CoreDiagnosticsTests.cs | 4 +- .../Infrastructure/TryContractTests.cs | 16 +- .../SdkContract/SdkMappingContractTests.cs | 10 +- .../Memory/MemoryAddressBuilderTests.cs | 7 + .../SdkContract/ConsumedSdkSurface.cs | 2 +- .../SdkContract/SdkApiUsage.cs | 2 +- 18 files changed, 425 insertions(+), 39 deletions(-) create mode 100644 libs/CheatEngine.Client.Abstractions/Memory/MemoryBytesReadOutcome.cs diff --git a/libs/CheatEngine.Client.Abstractions/Memory/IMemoryClient.cs b/libs/CheatEngine.Client.Abstractions/Memory/IMemoryClient.cs index 1b66ac6..aa0fb64 100644 --- a/libs/CheatEngine.Client.Abstractions/Memory/IMemoryClient.cs +++ b/libs/CheatEngine.Client.Abstractions/Memory/IMemoryClient.cs @@ -51,6 +51,18 @@ public bool TryReadBytes(MemoryBytesReadRequest request, out ImmutableArray ReadBytes(MemoryBytesReadRequest request, CancellationToken cancellationToken = default); + /// + /// Copies a caller-bounded byte range and reports the contiguous prefix Cheat Engine confirmed when it returned fewer + /// bytes than requested. + /// + /// + /// Like a Try method, it reports an expected host failure, a budget refusal and a cancellation before dispatch + /// through instead of throwing them; + /// reports the same read without its prefix. + /// + public MemoryBytesReadOutcome ReadBytesDetailed(MemoryBytesReadRequest request, + CancellationToken cancellationToken = default); + /// Tries to write an immutable byte request. public bool TryWriteBytes(MemoryBytesWriteRequest request, out CheatEngineFailure failure, CancellationToken cancellationToken = default); diff --git a/libs/CheatEngine.Client.Abstractions/Memory/MemoryBytesReadOutcome.cs b/libs/CheatEngine.Client.Abstractions/Memory/MemoryBytesReadOutcome.cs new file mode 100644 index 0000000..7d804da --- /dev/null +++ b/libs/CheatEngine.Client.Abstractions/Memory/MemoryBytesReadOutcome.cs @@ -0,0 +1,84 @@ +using System.Collections.Immutable; + +using CheatEngine.Client.Results; + +namespace CheatEngine.Client.Memory; + +/// +/// Describes one bounded byte read, including the contiguous prefix that Cheat Engine confirmed when the read did not +/// complete. +/// +/// +/// +/// CheatEngine.SDK verifies every byte it copies.

An unknown bitness is PointerSize.Unknown instead of a thrown context fault; the Core context records why (TargetNotAttached, the SDK status kind, or InvalidState) and reports it if the codec then returns false. An SDK fault while the facts are observed is still thrown as the context's own exception and converted by Core. The built-in Address codec reads and writes at the admitted Bitness. The primitive members of IMemoryClient, the batch requests and outcomes, MemoryAddressValue and the Fluent primitive terminals take where T : unmanaged, with the supported set of A5 documented on IMemoryClient: the 8- to 64-bit integers, float, double and Address. Any other T is refused with OperationRejected and NotStarted before dispatch, without a Cheat Engine call, instead of the former Unsupported kind inside the dispatched callback; the unreachable "not handled" plumbing is removed. The codec route is unchanged: the request carries the codec, and memory never resolves one implicitly; removing AddMemoryCodec stays with the DI lot. The string requests keep only the MemoryStringEncoding form: the bool constructors and WideCharacter go, MemoryStringReadRequest.Create and MemoryStringWriteRequest.CreateBounded remain, and an undefined encoding is refused (audit API-02e). MemoryBatchWriteEffectState gains Unknown = 0 (NotStarted 1, Partial 2, Complete 3) and leaves PendingCharterEnums; the batch outcomes rename Cause to Failure and Succeeded to IsSuccess (audit API-10). The benchmark suite gains MemoryBatchBenchmarks (audit A24-04): the Client cost of 1, 64 and 1024-element integer and Address batches over an in-memory port, described as the informational "memory-batch" workload; no host number is measured or published. The inline Core host moves to InlineCoreHost, shared with the AOB benchmark. ConsumedSdkSurface and SdkApiUsage record the PointerSize members the built-in Address codec now uses, and PublicAPI.Unshipped follows RS0016 and RS0017. The Abstractions README documents the two typed routes, the width facts on the contexts and the batch row of the Try/cancellation table; the root and Fluent READMEs name the supported set. The qualification harness takes IMemoryClient for its batch scenario and the encoding factories for its string scenario. Tests: an unsupported T (DateTime, char, bool, nint, decimal, Guid, Half) refused before dispatch on the four primitive paths; the unmanaged constraint on all ten primitive members; the default effect state is Unknown; the detailed batch outcomes; the codec context width facts, with an SDK fault while observing them; the encoding-only string requests; and the DI, Fluent and codec tests on the folded contracts. --- README.md | 2 +- .../Memory/IMemoryBatchClient.cs | 24 -- .../Memory/IMemoryClient.cs | 85 +++++-- .../Memory/IMemoryPointerWidthContext.cs | 61 ----- .../Memory/IMemoryReadContext.cs | 68 +++++- .../Memory/IMemoryWriteContext.cs | 65 ++++- .../Memory/MemoryAddressValue.cs | 5 +- .../Memory/MemoryBatchWriteEffectState.cs | 15 +- .../Memory/MemoryPrimitiveBatchReadOutcome.cs | 25 +- .../Memory/MemoryPrimitiveBatchReadRequest.cs | 5 +- .../MemoryPrimitiveBatchWriteOutcome.cs | 20 +- .../MemoryPrimitiveBatchWriteRequest.cs | 5 +- .../Memory/MemoryStringReadRequest.cs | 44 ++-- .../Memory/MemoryStringWriteRequest.cs | 54 ++--- .../PublicAPI.Unshipped.txt | 44 ++-- .../CheatEngine.Client.Abstractions/README.md | 27 ++- .../Domains/MemoryClient.cs | 228 +++++++++--------- .../Domains/PointerWidthPolicy.cs | 3 +- ...EngineClientServiceCollectionExtensions.cs | 2 - .../DefaultMemoryCodecs.cs | 52 ++-- .../CheatEngineMemoryFluentExtensions.cs | 5 +- .../Memory/Memory.cs | 5 +- .../Memory/MemoryAddressBuilder.cs | 4 + .../Memory/MemoryPrimitiveBatchBuilder.cs | 5 +- libs/CheatEngine.Client.Fluent/README.md | 4 +- .../Memory/MemoryBoundedRequestTests.cs | 24 +- ...emoryResourceLimitsAndBatchOutcomeTests.cs | 37 ++- .../BenchmarkSuiteMetadata.cs | 8 +- .../InlineCoreHost.cs | 62 +++++ .../MemoryBatchBenchmarks.cs | 162 +++++++++++++ ...PatternScannerMaterializationBenchmarks.cs | 45 +--- .../MemoryClientDispatchFailureTests.cs | 69 ++++-- ...lientResourceLimitsAndBatchOutcomeTests.cs | 68 ++++-- .../Domains/MemoryClientTests.cs | 6 +- .../MemoryCodecContextLifetimeTests.cs | 34 +-- .../Domains/MemoryPointerWidthTests.cs | 74 +++--- .../Infrastructure/CoreDiagnosticsTests.cs | 2 +- .../Infrastructure/TryContractTests.cs | 14 +- ...eClientServiceCollectionExtensionsTests.cs | 2 +- .../DefaultMemoryCodecsTests.cs | 21 +- .../Memory/MemoryAddressBuilderTests.cs | 33 ++- .../QualificationPlugin.cs | 2 +- .../QualificationScenarios.cs | 11 +- .../QualificationSession.cs | 4 +- .../README.md | 4 +- .../OutcomeEnumConventionTests.cs | 1 - .../SdkContract/ConsumedSdkSurface.cs | 7 + .../SdkContract/SdkApiUsage.cs | 1 + 48 files changed, 963 insertions(+), 585 deletions(-) delete mode 100644 libs/CheatEngine.Client.Abstractions/Memory/IMemoryBatchClient.cs delete mode 100644 libs/CheatEngine.Client.Abstractions/Memory/IMemoryPointerWidthContext.cs create mode 100644 tests/CheatEngine.Client.Benchmarks/InlineCoreHost.cs create mode 100644 tests/CheatEngine.Client.Benchmarks/MemoryBatchBenchmarks.cs diff --git a/README.md b/README.md index f0b0b01..b7841ef 100644 --- a/README.md +++ b/README.md @@ -244,7 +244,7 @@ following table is a delivery statement, not a substitute for a live host check. |-----------------------------------------------------|---------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Lifecycle, dispatch, DI, modules, options | Available | Per-enable provider and scope; modules stop in reverse order | | Runtime facts and selected process | Available | Snapshot and attachment state are re-read through the active host | -| Typed memory and finite pointer chains | Available | Built-in primitives plus explicitly registered deterministic codecs; strings and byte ranges are bounded | +| Typed memory and finite pointer chains | Available | Built-in primitives (8- to 64-bit integers, float, double, Address) plus codecs passed with each request; strings and byte ranges are bounded | | Modules, regions, symbols, and custom-symbol leases | Available | Results are copied; leases are activation-scoped | | AOB scanning | Available | Patterns are normalized; terminals are `FirstOrNone`, `RequireSingle`, or materialization-bounded `Take` (post-filtered global scan) | | Address List and memory records | Available | Snapshots and hierarchy materialization are bounded; table file access requires an allowed root | diff --git a/libs/CheatEngine.Client.Abstractions/Memory/IMemoryBatchClient.cs b/libs/CheatEngine.Client.Abstractions/Memory/IMemoryBatchClient.cs deleted file mode 100644 index 709e12e..0000000 --- a/libs/CheatEngine.Client.Abstractions/Memory/IMemoryBatchClient.cs +++ /dev/null @@ -1,24 +0,0 @@ -namespace CheatEngine.Client.Memory; - -/// Executes primitive batches while preserving their per-operation outcome details. -/// -/// -/// Call-only.

The port now calls CheatEngine.SDK's AobScanner.TryScanOutcome with its target context and returns an internal AobHostOutcome: the SDK kind, the Lua status, the verified count and the two target observations made around the call. AobScanHostStatus is gone (audit F06, SDK2-04). AobScanMapping classifies each outcome, value by value: - Matches: the copied addresses; NoMatches (a valid empty list): the factual empty success. - NoResult: IndeterminateHostResult with Completed and the message "CE AOBScan returned nil: on CE 7.7 zero matches and host failures share this shape"; never NotFound (CRIT-03). - GlobalUnavailable: CapabilityUnavailable with NotStarted. - ProtectedLuaFailure: LuaError with Unknown, naming the Lua status. - InvalidResult and ResultListCountUnavailable: InvalidHostResult with Completed. - Unknown or an undefined value: IndeterminateHostResult with Unknown. - Matches or NoMatches without a list, or a list handed out with any other outcome: InvalidHostResult; such a list is still released. When the selected target changes during the scan (another incarnation or PID), its addresses are discarded and the scan fails with TargetChanged; when the identity is lost or gained between the two observations it fails with TargetIdentityUnavailable, both with Completed. A NoResult on a changed target is reported the same way. An unqualified target (CEServer, file as process) whose selection did not change keeps its answer, unverified. The result list is released through Owned .ReleaseWithOutcome, mapped with SdkReleaseOutcomes: any status but Released is CleanupUnconfirmed. A scan that had succeeded fails with InvalidState and discards its copy; a scan that had already failed keeps its kind and gains the CleanupUnconfirmed effect instead of being replaced by InvalidState. IAobMatchList.Release returns the SDK status and never throws; a port that breaks that contract is recorded as an unconfirmed release, so no SDK exception crosses TryScan. OwnershipHandoff stays the single release authority between the SDK owner and the published match list (F13). Its rollback now takes a release delegate that returns a LeaseReleaseOutcome, so the SDK adapter rolls back through ReleaseWithOutcome as well; an unconfirmed rollback is reported with the publication failure. The port's null guard still keeps an owner-less success from reaching Adopt. The fault path that reads the SDK-owned list now goes through SdkBoundary.Classify, so the external-reset rule applies to it. SanctionedSdkLuaSurface swaps Owned`1::Dispose for Owned`1::ReleaseWithOutcome 1:1: the same owner, released by the same authority, through the never-throwing SDK member. ConsumedSdkSurface and SdkApiUsage follow (TryScanOutcome, the outcome and context getters, ReleaseWithOutcome, TargetReleaseOutcome.Status and the incarnation equality). The Abstractions and Core READMEs describe the outcome table and the release rule, and the Patterns row of the Try/cancellation table lists the new effects. Tests: the five F06 cases (absent global, nil result, protected error, malformed result, empty list) plus a target change, a reused PID, a lost and a gained identity during the scan; the verdict table; totality over AobScanOutcomeKind and over TargetReleaseStatus through the scanner; an owner-less success and a list handed out with a failure; the copy fault through SdkBoundary; OwnershipHandoffTests on the release delegate; the TryScanOutcome static binding case in TryContractTests. The AOB doubles move to TestSupport. --- .../CheatEngine.Client.Abstractions/README.md | 28 +- .../Scanning/IPatternScanner.cs | 13 +- .../Domains/AobHostOutcome.cs | 33 ++ .../Domains/AobScanHostStatus.cs | 20 -- .../Domains/AobScanMapping.cs | 168 +++++++++ .../Domains/IAobMatchList.cs | 12 +- .../Domains/IAobScanPort.cs | 13 +- .../Domains/PatternScanner.cs | 143 ++++---- .../Domains/SdkAobScanPort.cs | 53 ++- .../Domains/SdkRuntimeObservationPort.cs | 3 +- .../Domains/TargetSelectionFacts.cs | 10 +- .../Infrastructure/OwnershipHandoff.cs | 41 ++- libs/CheatEngine.Client.Core/README.md | 17 +- libs/CheatEngine.Client.Fluent/README.md | 5 +- .../Scanning/AobFirstMatchBuilder.cs | 8 +- .../Scanning/AobSingleMatchBuilder.cs | 7 +- ...PatternScannerMaterializationBenchmarks.cs | 10 +- .../Domains/PatternScannerBehaviorTests.cs | 250 +++----------- .../Domains/PatternScannerHostOutcomeTests.cs | 325 ++++++++++++++++++ .../Infrastructure/CoreDiagnosticsTests.cs | 9 +- .../Infrastructure/OwnershipHandoffTests.cs | 91 ++++- .../Infrastructure/TryContractTests.cs | 9 +- .../TestSupport/AobScanDoubles.cs | 225 ++++++++++++ .../Architecture/ArchitectureRatchetTests.cs | 9 +- .../SdkContract/ConsumedSdkSurface.cs | 15 +- .../SdkContract/SdkApiUsage.cs | 11 +- 26 files changed, 1153 insertions(+), 375 deletions(-) create mode 100644 libs/CheatEngine.Client.Core/Domains/AobHostOutcome.cs delete mode 100644 libs/CheatEngine.Client.Core/Domains/AobScanHostStatus.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/AobScanMapping.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Domains/PatternScannerHostOutcomeTests.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/TestSupport/AobScanDoubles.cs diff --git a/libs/CheatEngine.Client.Abstractions/README.md b/libs/CheatEngine.Client.Abstractions/README.md index 218545e..de68d73 100644 --- a/libs/CheatEngine.Client.Abstractions/README.md +++ b/libs/CheatEngine.Client.Abstractions/README.md @@ -165,11 +165,27 @@ Four scan limits are distinct and must not be confused: scope, and the Cheat Engine scan time (`HostScanElapsed`) separately from the Client copy time (`MaterializationElapsed`).

When the port's TargetSelection.ObserveCurrent observation qualifies Cheat Engine's selected target, the request runs CheatEngine.SDK's stable AobScanner.TryScanWithinBounds, the exhaustive MemScan route whose Cheat Engine work is limited to [Start, Stop) (audit F07, SDK2-05). Only the overload without a call deadline is used; the deadline and first-found overloads stay out (SdkExperimentalApiRatchetTests). Bounds: AobScanBounds.TryFromModule of the resolved module intersected with the range, whose inclusive end becomes Stop = End + pattern length, checked and saturated at the last address. A range that does not overlap the module, or that leaves no room below the top of the address space, is refused with OperationRejected and NotStarted before any scan, on both routes. The destination is a span of min(MaximumResults + 1, ScanResourceLimits.MaximumPatternMatches) addresses (65,536), so a full destination proves truncation; the caller's token is passed to the SDK. The Client's range and module checks stay as defensive post-filters, and what they drop is counted. AobScanMapping.ClassifyBounded maps AobBoundedScanOutcomeKind: - Matches: publish; NoMatches: the factual empty success, but only when IsHostErrorTextUnreadable is false, otherwise IndeterminateHostResult with Completed. - HostReportedError: OperationRejected with Completed, carrying the SDK's bounded, unparsed text. - InvalidBounds: OperationRejected with NotStarted. - TargetChanged: TargetChanged; RuntimeInvalidated: RuntimeChanged; ScanFailed: LuaError; InvalidResult: InvalidHostResult; each with Completed after the scan completed and Unknown before. - Cancelled: Cancelled, NotStarted before the scan completed and Completed after it (the SDK's host scan time is the milestone). - WaitTimedOut, Unknown and undefined values: IndeterminateHostResult with Unknown. - SessionCreationFailed and TargetIdentityUnavailable: fall back. The fallback, like an unqualified target (CEServer, file as process, an unobservable selection), runs the global AOBScan with the module and range as managed post-filters. The session release the SDK reports is checked: both owners must be Released and a pending stop confirmed or not required. Anything else is CleanupUnconfirmed, discards the copy, and prevents a fallback; a creation whose rollback was not confirmed is never hidden behind one either. PatternScanScope gains GlobalHostScan (1) and HostBoundedRange (2); GlobalHostScanWithManagedFilter becomes 3 and now names only the fallback. The scopes land here rather than with the outcome fold because ScanDetailed must not label a bounded scan as a global one. Until PatternScanMetrics widens its counts, the host result count is saturated at int.MaxValue; the rows the SDK reads never exceed it. The port gains TryScanWithinBounds and ObserveSelection (delegated to SdkRuntimeObservationPort, still the only caller of TargetSelection) and copies the SDK result into AobBoundedHostResult. SdkAobScanPort already has its sonar coverage exclusion, so no new Sdk*Port file and no sonar.yml change are needed. ConsumedSdkSurface and SdkApiUsage record the bounded members. The XML docs, the Abstractions, Core, Fluent and root READMEs and the template state which route answers what and at what cost: the bounded scan blocks Cheat Engine's main thread and cannot be interrupted once started; only it reports a factual zero. The Patterns row of the Try/cancellation table names the SDK's cancellation points. Tests (Q28, Q29): module bounds, the factual zero, the unreadable error text, the host error text, the End to Stop conversion including saturation at the top of the address space, the module and range intersection and a disjoint range on both routes, truncation and the destination cap, the defensive post-filters and the SDK skip counts, the four fallbacks, an unconfirmed rollback, session release and stop, every failure kind, cancellation before and after the native call and at the SDK's milestones, SDK faults from the observation and the scan, and totality over AobBoundedScanOutcomeKind. --- README.md | 14 +- .../PublicAPI.Unshipped.txt | 4 +- .../CheatEngine.Client.Abstractions/README.md | 65 +- .../Scanning/AobScanRange.cs | 11 +- .../Scanning/AobScanRequest.cs | 24 +- .../Scanning/IPatternScanner.cs | 60 +- .../Scanning/PatternScanMetrics.cs | 21 +- .../Scanning/PatternScanScope.cs | 21 +- .../Domains/AobBoundedHostResult.cs | 144 +++++ .../Domains/AobScanMapping.cs | 202 +++++- .../Domains/IAobScanPort.cs | 17 + .../Domains/PatternScanner.cs | 346 ++++++++-- .../Domains/ScanResourceLimits.cs | 19 + .../Domains/SdkAobScanPort.cs | 42 ++ libs/CheatEngine.Client.Core/README.md | 12 +- libs/CheatEngine.Client.Fluent/README.md | 25 +- .../Scanning/AobFirstMatchBuilder.cs | 10 +- .../Scanning/AobManyMatchBuilder.cs | 11 +- .../Scanning/AobScanBuilder.cs | 71 +- .../Scanning/AobSingleMatchBuilder.cs | 11 +- .../Modules/PluginClientModule.cs | 14 +- ...PatternScannerMaterializationBenchmarks.cs | 12 + .../PatternScannerBoundedRouteTests.cs | 605 ++++++++++++++++++ .../Infrastructure/CoreDiagnosticsTests.cs | 13 +- .../Infrastructure/TryContractTests.cs | 6 + .../TestSupport/AobScanDoubles.cs | 130 +++- .../SdkContract/ConsumedSdkSurface.cs | 33 + .../SdkContract/SdkApiUsage.cs | 29 +- 28 files changed, 1796 insertions(+), 176 deletions(-) create mode 100644 libs/CheatEngine.Client.Core/Domains/AobBoundedHostResult.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/ScanResourceLimits.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Domains/PatternScannerBoundedRouteTests.cs diff --git a/README.md b/README.md index b7841ef..9fe5d58 100644 --- a/README.md +++ b/README.md @@ -150,11 +150,13 @@ Address address = client.Patterns client.Memory.At(address + 0x14).Write(999); ``` -`InModule(...)` and `InRange(...)` are managed post-filters: Cheat Engine still runs one global `AOBScan` over the whole -target, and Core copies only the addresses inside the module or range. `Take(n)`, `FirstOrNone()` and `RequireSingle()` -bound only how many filtered addresses Core copies; they never stop Cheat Engine early, and `FirstOrNone()` follows -Cheat Engine's unspecified result-list order.

176/321] Replace SDK AOB options with Client-owned options The AOB request and the Fluent builder stop exposing CheatEngine.SDK's AobScanOptions and FastScanMethod, which coupled the 1.x public surface to SDK option types (audit API-04, arbitration A7). Abstractions gains two Client values: - ScanProtectionFilter(executable, copyOnWrite, writable): one ScanProtectionRequirement per Cheat Engine flag, Unspecified = 0 (the flag is left out), Required (+), Excluded (-) and Any (*). The constructor refuses an undefined requirement; the default filter is all unspecified. - ScanAlignment: None (the default), AlignedTo(int) with a positive divisor, and LastDigits(string) with one to sixteen hexadecimal digits normalized to upper case, described by ScanAlignmentKind (None = 0, AlignedTo, LastDigits). AobScanRequest becomes (pattern, maximumResults, ModuleName? module, AobScanRange? range, ScanProtectionFilter protection, ScanAlignment alignment), with Protection and Alignment in place of Options, and AobScanOptionsNormalizer is gone. Core translates both values into the SDK options in AobScanMapping.ToSdkOptions: the protection text in Cheat Engine's order (+X-C-W for executable code), and the fast-scan method with its decimal divisor or digits, on both routes. TryValidateRequest refuses a value that only memory tampering could make undefined, before dispatch. Fluent follows in the same commit (A7), so it is reshaped once: AobScanBuilder exposes Protection and Alignment and offers Executable() (+X-C-W, unchanged), Writable() (-C+W: writable data that is not copy-on-write, executable or not), WithProtection(filter), AlignedTo(int) and WithLastDigits(string); each replaces the current filter or rule and validates at configuration time. The ReadableExecutable alias, WithProtectionFlags(string?) and WithAlignment(FastScanMethod, string?) are removed (audit API-02f). FastScanMethod and AobScanOptions leave ApprovedSdkClientTypes, so PublicClientSignatureBoundaryTests now keeps them out of every public signature. OutcomeEnumConventionTests records ScanAlignmentKind and ScanProtectionRequirement as option enums whose zero is the valid default. PublicAPI.Unshipped follows RS0016 and RS0017, and ConsumedSdkSurface and SdkApiUsage move the option usage from Abstractions and Fluent to Core. The root and Fluent READMEs and the template use Executable(), and the Abstractions and Fluent READMEs describe the two option values. The qualification harness, the benchmarks and the Core, Fluent and Abstractions tests build their requests without SDK options. Tests: the request keeps its protection and alignment and defaults to an unspecified filter without alignment; the alignment factories normalize and refuse bad divisors and digits; the filter refuses an undefined requirement; the protection text and fast-scan translation; the options reach both routes; a tampered value is refused before dispatch; the Fluent presets, WithProtection, WithLastDigits and AlignedTo with their configuration-time refusals. --- README.md | 2 +- .../PublicAPI.Unshipped.txt | 41 ++++- .../CheatEngine.Client.Abstractions/README.md | 6 + .../Scanning/AobScanOptionsNormalizer.cs | 160 ------------------ .../Scanning/AobScanRequest.cs | 38 +++-- .../Scanning/ScanAlignment.cs | 87 ++++++++++ .../Scanning/ScanAlignmentKind.cs | 23 +++ .../Scanning/ScanProtectionFilter.cs | 59 +++++++ .../Scanning/ScanProtectionRequirement.cs | 22 +++ .../Domains/AobScanMapping.cs | 56 ++++++ .../Domains/PatternScanner.cs | 32 +++- .../PublicAPI.Unshipped.txt | 10 +- libs/CheatEngine.Client.Fluent/README.md | 10 +- .../Scanning/AobScanBuilder.cs | 88 +++++----- .../CheatEngineAobFluentExtensions.cs | 4 +- .../ApprovedSdkClientTypes.cs | 2 - .../Modules/PluginClientModule.cs | 2 +- .../Scanning/AobPatternTests.cs | 93 ++++++---- ...PatternScannerMaterializationBenchmarks.cs | 2 +- .../Domains/PatternScannerBehaviorTests.cs | 2 +- .../PatternScannerBoundedRouteTests.cs | 4 +- .../Domains/PatternScannerHostOutcomeTests.cs | 2 +- .../Domains/PatternScannerTests.cs | 109 +++++++++++- .../Infrastructure/CoreDiagnosticsTests.cs | 2 +- .../Infrastructure/TryContractTests.cs | 2 +- .../Scanning/AobFluentBuilderTests.cs | 46 ++--- .../QualificationScenarios.cs | 5 +- .../OutcomeEnumConventionTests.cs | 5 +- .../SdkContract/ConsumedSdkSurface.cs | 15 +- .../SdkContract/SdkApiUsage.cs | 4 - 30 files changed, 627 insertions(+), 306 deletions(-) delete mode 100644 libs/CheatEngine.Client.Abstractions/Scanning/AobScanOptionsNormalizer.cs create mode 100644 libs/CheatEngine.Client.Abstractions/Scanning/ScanAlignment.cs create mode 100644 libs/CheatEngine.Client.Abstractions/Scanning/ScanAlignmentKind.cs create mode 100644 libs/CheatEngine.Client.Abstractions/Scanning/ScanProtectionFilter.cs create mode 100644 libs/CheatEngine.Client.Abstractions/Scanning/ScanProtectionRequirement.cs diff --git a/README.md b/README.md index 9fe5d58..54ce033 100644 --- a/README.md +++ b/README.md @@ -143,7 +143,7 @@ handle-free: Address address = client.Patterns .Aob("48 8B ?? ?? ?? 89") .InModule("game.exe") - .ReadableExecutable() + .Executable() .RequireSingle() .Execute(); diff --git a/libs/CheatEngine.Client.Abstractions/PublicAPI.Unshipped.txt b/libs/CheatEngine.Client.Abstractions/PublicAPI.Unshipped.txt index 272b73e..58b3f75 100644 --- a/libs/CheatEngine.Client.Abstractions/PublicAPI.Unshipped.txt +++ b/libs/CheatEngine.Client.Abstractions/PublicAPI.Unshipped.txt @@ -594,13 +594,14 @@ CheatEngine.Client.Scanning.AobScanRange.End.get -> CheatEngine.SDK.Engine.Value CheatEngine.Client.Scanning.AobScanRange.Equals(CheatEngine.Client.Scanning.AobScanRange other) -> bool CheatEngine.Client.Scanning.AobScanRange.Start.get -> CheatEngine.SDK.Engine.Values.Address CheatEngine.Client.Scanning.AobScanRequest +CheatEngine.Client.Scanning.AobScanRequest.Alignment.get -> CheatEngine.Client.Scanning.ScanAlignment CheatEngine.Client.Scanning.AobScanRequest.AobScanRequest() -> void -CheatEngine.Client.Scanning.AobScanRequest.AobScanRequest(CheatEngine.Client.Scanning.AobPattern pattern, CheatEngine.SDK.Engine.Scanning.Aob.AobScanOptions options, int maximumResults, CheatEngine.SDK.Engine.Inspection.ModuleName? module = null, CheatEngine.Client.Scanning.AobScanRange? range = null) -> void +CheatEngine.Client.Scanning.AobScanRequest.AobScanRequest(CheatEngine.Client.Scanning.AobPattern pattern, int maximumResults, CheatEngine.SDK.Engine.Inspection.ModuleName? module = null, CheatEngine.Client.Scanning.AobScanRange? range = null, CheatEngine.Client.Scanning.ScanProtectionFilter protection = default(CheatEngine.Client.Scanning.ScanProtectionFilter), CheatEngine.Client.Scanning.ScanAlignment alignment = default(CheatEngine.Client.Scanning.ScanAlignment)) -> void CheatEngine.Client.Scanning.AobScanRequest.Equals(CheatEngine.Client.Scanning.AobScanRequest other) -> bool CheatEngine.Client.Scanning.AobScanRequest.MaximumResults.get -> int CheatEngine.Client.Scanning.AobScanRequest.Module.get -> CheatEngine.SDK.Engine.Inspection.ModuleName? -CheatEngine.Client.Scanning.AobScanRequest.Options.get -> CheatEngine.SDK.Engine.Scanning.Aob.AobScanOptions CheatEngine.Client.Scanning.AobScanRequest.Pattern.get -> CheatEngine.Client.Scanning.AobPattern +CheatEngine.Client.Scanning.AobScanRequest.Protection.get -> CheatEngine.Client.Scanning.ScanProtectionFilter CheatEngine.Client.Scanning.AobScanRequest.Range.get -> CheatEngine.Client.Scanning.AobScanRange?

IPatternScanner gains ScanDetailed, and IPatternScanOutcomeClient and its DI registration are removed; the DI tests assert that the scanner is registered once, as the Core singleton, with no outcome companion. PatternScanOutcome takes the 1.0 shape: IsSuccess, Result, Failure, Metrics, HostOutcome, RouteReason and TargetIdentityVerified (Cause and Succeeded are renamed). Its constructor also refuses a success that reports a host outcome other than Matches or NoMatches or no route, and a failure that claims a verified target. - PatternScanHostOutcome (Unknown = 0, Matches, NoMatches, NoResult, GlobalUnavailable, ProtectedLuaFailure, InvalidResult, ResultListCountUnavailable, HostReportedError, TargetChanged, TargetIdentityUnavailable, RuntimeInvalidated, Cancelled, ScanFailed) is what the host reported, before the Client's verdict: a global scan whose target changed reports Matches with a TargetChanged failure. InvalidBounds, SessionCreationFailed and WaitTimedOut have no host outcome and stay Unknown. - PatternScanRouteReason (Unknown = 0, UnscopedRequest, ScopedRequestOnQualifiedTarget, TargetIdentityNotQualified) says why the scan ran on its route; a fallback reports TargetIdentityNotQualified, and a refusal before any route Unknown. - TargetIdentityVerified is true on a successful bounded scan, and on a successful global scan only when the SDK saw the same qualified incarnation before and after the call; never on a failure. PatternScanMetrics becomes (Scope, ulong HostResultCount, ulong ExaminedCount, ulong FilteredOutCount, int MaterializedCount, BelowStartSkipped, AtOrAfterStopSkipped, UnreadHostRows, InBoundsCountIsExact, HostScanElapsed, MaterializationElapsed). The host count is no longer saturated at int.MaxValue; HostMatchCount is replaced by HostResultCount. The constructor enforces examined plus unread equals the host count, the copied and filtered rows within the examined ones, the skips within the filtered ones, and an exact count only when every row was read. The PatternScanScope values landed with the bounded route in the previous commit. The diagnostics event 1500 names the host result count; it is passed as a saturated long, so the Q46 argument-type rule of the diagnostic tests is unchanged. The XML docs and the Abstractions README state, for each route, the answer it gives and its cost: the global scan costs a full scan and cannot prove a zero; the bounded scan costs its bounds, proves a zero when the error text was read, blocks Cheat Engine's main thread and cannot be interrupted in 1.0; the fallback costs a full scan. The README describes the outcome fields and the Try/cancellation table names ScanDetailed on IPatternScanner. AobRouteComparisonBenchmarks (CRIT-16) compares the Client cost of a module request on the global post-filter route and on the bounded route over a fake port, registered as the informational "aob-route-comparison" workload. Cheat Engine's scan time is excluded and no host number is published. The qualification harness takes IPatternScanner and writes the widened counts, a compile fix only. Tests: the host outcome, route reason and verified target of the unscoped, bounded, fallback and refused paths; the widened bounded and global metrics, including skips, unread rows and exact counts; totality of the host outcome over AobScanOutcomeKind and AobBoundedScanOutcomeKind; the outcome and metrics constructor rules. --- .../PublicAPI.Unshipped.txt | 44 ++- .../CheatEngine.Client.Abstractions/README.md | 33 ++- .../Scanning/AobScanRequest.cs | 2 +- .../Scanning/IPatternScanOutcomeClient.cs | 28 -- .../Scanning/IPatternScanner.cs | 86 +++--- .../Scanning/PatternScanHostOutcome.cs | 70 +++++ .../Scanning/PatternScanMetrics.cs | 129 ++++++--- .../Scanning/PatternScanOutcome.cs | 132 +++++++-- .../Scanning/PatternScanRouteReason.cs | 28 ++ .../Domains/AobScanMapping.cs | 47 ++++ .../Domains/PatternScanner.cs | 136 +++++++--- .../Infrastructure/ICoreDiagnostics.cs | 8 +- libs/CheatEngine.Client.Core/README.md | 4 +- ...EngineClientServiceCollectionExtensions.cs | 2 - .../ClientCoreDiagnosticsLog.cs | 4 +- .../LoggerCoreDiagnostics.cs | 8 +- libs/CheatEngine.Client.Fluent/README.md | 4 +- .../Scanning/PatternScanOutcomeTests.cs | 139 ++++++---- .../AobRouteComparisonBenchmarks.cs | 178 ++++++++++++ .../BenchmarkSuiteMetadata.cs | 6 + .../Domains/PatternScannerBehaviorTests.cs | 34 +-- .../PatternScannerBoundedRouteTests.cs | 22 +- .../PatternScannerDetailedOutcomeTests.cs | 254 ++++++++++++++++++ .../Infrastructure/CoreDiagnosticsTests.cs | 6 +- .../Infrastructure/HostResourceLeaseTests.cs | 2 +- ...eClientServiceCollectionExtensionsTests.cs | 20 +- .../LoggerCoreDiagnosticsTests.cs | 2 +- .../Scanning/AobFluentBuilderTests.cs | 5 + .../QualificationPlugin.cs | 2 +- .../QualificationScenarios.cs | 31 ++- .../QualificationSession.cs | 4 +- 31 files changed, 1180 insertions(+), 290 deletions(-) delete mode 100644 libs/CheatEngine.Client.Abstractions/Scanning/IPatternScanOutcomeClient.cs create mode 100644 libs/CheatEngine.Client.Abstractions/Scanning/PatternScanHostOutcome.cs create mode 100644 libs/CheatEngine.Client.Abstractions/Scanning/PatternScanRouteReason.cs create mode 100644 tests/CheatEngine.Client.Benchmarks/AobRouteComparisonBenchmarks.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Domains/PatternScannerDetailedOutcomeTests.cs diff --git a/libs/CheatEngine.Client.Abstractions/PublicAPI.Unshipped.txt b/libs/CheatEngine.Client.Abstractions/PublicAPI.Unshipped.txt index 58b3f75..13437f5 100644 --- a/libs/CheatEngine.Client.Abstractions/PublicAPI.Unshipped.txt +++ b/libs/CheatEngine.Client.Abstractions/PublicAPI.Unshipped.txt @@ -609,10 +609,9 @@ CheatEngine.Client.Scanning.AobScanResult.AobScanResult(System.Collections.Immut CheatEngine.Client.Scanning.AobScanResult.Equals(CheatEngine.Client.Scanning.AobScanResult other) -> bool CheatEngine.Client.Scanning.AobScanResult.IsTruncated.get -> bool CheatEngine.Client.Scanning.AobScanResult.Matches.get -> System.Collections.Immutable.ImmutableArray -CheatEngine.Client.Scanning.IPatternScanOutcomeClient -CheatEngine.Client.Scanning.IPatternScanOutcomeClient.ScanDetailed(CheatEngine.Client.Scanning.AobScanRequest request, System.Threading.CancellationToken cancellationToken = default(System.Threading.CancellationToken)) -> CheatEngine.Client.Scanning.PatternScanOutcome!

The same module request could therefore return a match straddling the module end on a CEServer or file-as-process target and not on a qualified local one. Both routes now copy through one predicate: a module keeps a match only when all of its pattern bytes lie inside it, and a range keeps a match whose start lies in [Start, End]. On the bounded route this turns the host observation into a Client guarantee. Bounds that cannot hold one whole match (a range ending just before the module, a module smaller than the pattern) are refused before any scan on both routes. The 65,535-address copy cap now applies to the global route too, so IsTruncated means the same thing on every route. A fallback never reports a verified target identity, as the plan requires, so the flag cannot contradict its TargetIdentityNotQualified reason. The default protection filter is sent as the SDK-documented empty text on both routes instead of an omitted or nil argument. The XML docs and READMEs state the rule once, the fake port's global context follows the observed selection, and the Q28 harness check uses the same module rule. --- .../CheatEngine.Client.Abstractions/README.md | 33 ++++-- .../Scanning/AobScanRange.cs | 11 +- .../Scanning/AobScanRequest.cs | 20 ++-- .../Scanning/AobScanResult.cs | 5 +- .../Scanning/IPatternScanner.cs | 26 ++-- .../Scanning/PatternScanOutcome.cs | 8 +- .../Scanning/PatternScanRouteReason.cs | 4 +- .../Scanning/ScanProtectionFilter.cs | 7 +- .../Domains/AobScanMapping.cs | 32 +++-- .../Domains/PatternScanner.cs | 105 ++++++++++++---- .../Domains/ScanResourceLimits.cs | 3 +- libs/CheatEngine.Client.Core/README.md | 7 +- .../Scanning/AobScanBuilder.cs | 26 ++-- .../PatternScannerBoundedRouteTests.cs | 112 +++++++++++++++++- .../PatternScannerDetailedOutcomeTests.cs | 6 + .../Domains/PatternScannerTests.cs | 35 +++++- .../TestSupport/AobScanDoubles.cs | 16 +-- .../QualificationScenarios.cs | 16 ++- 18 files changed, 367 insertions(+), 105 deletions(-) diff --git a/libs/CheatEngine.Client.Abstractions/README.md b/libs/CheatEngine.Client.Abstractions/README.md index 6aa72de..6444357 100644 --- a/libs/CheatEngine.Client.Abstractions/README.md +++ b/libs/CheatEngine.Client.Abstractions/README.md @@ -152,24 +152,32 @@ No CheatEngine.SDK primitive backs these yet; they may arrive in a 1.x minor rel |-----------------------------------|-------------------------------------------------------------------------------------|---------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------| | `GlobalHostScan` | No module and no range (`UnscopedRequest`) | Exact matches; zero matches are `IndeterminateHostResult` | One global `AOBScan` over the whole target | | `HostBoundedRange` | A module and/or range, on a qualified local target (`ScopedRequestOnQualifiedTarget`) | Exact matches; zero matches are a factual empty result when the error text was read | An exhaustive MemScan limited to the module intersected with the range; blocks Cheat Engine's main thread and cannot be interrupted once started in 1.0 | -| `GlobalHostScanWithManagedFilter` | A module and/or range whose bounded route cannot run (`TargetIdentityNotQualified`) | Exact matches inside the module and range; zero matches are `IndeterminateHostResult` | One global `AOBScan` over the whole target; Core keeps only the addresses that start inside the module and range | +| `GlobalHostScanWithManagedFilter` | A module and/or range whose bounded route cannot run (`TargetIdentityNotQualified`) | Exact matches inside the module and range; a list without such a match is an empty success; a `nil` list is `IndeterminateHostResult` | One global `AOBScan` over the whole target, after the bounded scan when that scan had run; Core applies the module and range while copying | The bounded route runs when `TargetSelection.ObserveCurrent` qualifies Cheat Engine's selected target as a local process incarnation.

A read count or a read row now keeps the bounded metrics on those failures. Session creation failures are classified per MemoryScanCreationStatus: only the statuses after which the SDK holds no MemScan object fall back to the global scan. An unconfirmed rollback, Unknown, a contradictory Success or a status a later 2.x SDK adds fails closed as InvalidState with CleanupUnconfirmed, and a totality test covers the enum. OwnershipHandoff now throws a typed OwnershipHandoffException that carries the release kind, so PatternScanner reports an unpublished list whose release was not confirmed as CleanupUnconfirmed instead of an Unknown AggregateException. A cancellation observed before the fallback reports the bounded attempt that ran rather than a global route that never did, and a fallback after a completed bounded scan adds that scan's time to HostScanElapsed. New tests end the activation during the copy fault, sweep every SDK fault type through the target observation and the bounded scan, and cover both fallback cancellation milestones. --- .../Scanning/PatternScanMetrics.cs | 4 + .../Domains/AobScanMapping.cs | 67 +++++++-- .../Domains/IAobScanPort.cs | 3 + .../Domains/PatternScanner.cs | 51 ++++++- .../Domains/SdkAobScanPort.cs | 4 +- .../Infrastructure/OwnershipHandoff.cs | 17 +-- .../OwnershipHandoffException.cs | 55 ++++++++ libs/CheatEngine.Client.Core/README.md | 3 +- .../PatternScannerBoundedRouteTests.cs | 133 ++++++++++++++++++ .../Domains/PatternScannerHostOutcomeTests.cs | 59 ++++++++ .../Infrastructure/OwnershipHandoffTests.cs | 19 +-- .../Infrastructure/TryContractTests.cs | 79 +++++++++++ .../TestSupport/AobScanDoubles.cs | 8 +- 13 files changed, 461 insertions(+), 41 deletions(-) create mode 100644 libs/CheatEngine.Client.Core/Infrastructure/OwnershipHandoffException.cs diff --git a/libs/CheatEngine.Client.Abstractions/Scanning/PatternScanMetrics.cs b/libs/CheatEngine.Client.Abstractions/Scanning/PatternScanMetrics.cs index 51c4821..a49a72a 100644 --- a/libs/CheatEngine.Client.Abstractions/Scanning/PatternScanMetrics.cs +++ b/libs/CheatEngine.Client.Abstractions/Scanning/PatternScanMetrics.cs @@ -161,6 +161,10 @@ public bool InBoundsCountIsExact } /// Gets the elapsed time of the Cheat Engine scan call only (host scan time). + /// + /// On , when a bounded scan had run before + /// CheatEngine.SDK lost the target's identity, it also includes that scan's time: the request cost both scans. + /// public TimeSpan HostScanElapsed { get; diff --git a/libs/CheatEngine.Client.Core/Domains/AobScanMapping.cs b/libs/CheatEngine.Client.Core/Domains/AobScanMapping.cs index 753e5cb..9de9095 100644 --- a/libs/CheatEngine.Client.Core/Domains/AobScanMapping.cs +++ b/libs/CheatEngine.Client.Core/Domains/AobScanMapping.cs @@ -79,7 +79,8 @@ namespace CheatEngine.Client.Core.Domains; /// SessionCreationFailed, TargetIdentityUnavailable /// /// Fall back to the global route with managed post-filters; a creation whose rollback Cheat Engine did not -/// confirm is InvalidState, CleanupUnconfirmed instead. +/// confirm, or whose creation status this Client does not recognize, is InvalidState, +/// CleanupUnconfirmed instead (). /// /// /// TargetChangedTargetChanged @@ -232,17 +233,8 @@ internal static AobBoundedDisposition ClassifyBounded(string operation, in AobBo "CheatEngine.SDK refused the bounded AOB scan before any Cheat Engine call: its bounds are empty.", null, CheatEngineHostEffect.NotStarted); return AobBoundedDisposition.Fail; - case AobBoundedScanOutcomeKind.SessionCreationFailed - when result.CreationStatus == MemoryScanCreationStatus.RollbackUnconfirmed: - failure = new CheatEngineFailure(CheatEngineFailureKind.InvalidState, operation, - "The bounded AOB scan session could not be created, and Cheat Engine did not confirm its rollback.", - null, CheatEngineHostEffect.CleanupUnconfirmed); - return AobBoundedDisposition.Fail; case AobBoundedScanOutcomeKind.SessionCreationFailed: - failure = new CheatEngineFailure(CheatEngineFailureKind.CapabilityUnavailable, operation, - $"The bounded AOB scan session could not be created ({result.CreationStatus}).", null, - CheatEngineHostEffect.NotStarted); - return AobBoundedDisposition.FallBack; + return ClassifyCreationFailure(operation, result.CreationStatus, out failure); case AobBoundedScanOutcomeKind.TargetIdentityUnavailable: failure = new CheatEngineFailure(CheatEngineFailureKind.TargetIdentityUnavailable, operation, "The selected target could not be qualified during the bounded AOB scan; nothing was published.", @@ -288,6 +280,52 @@ internal static AobBoundedDisposition ClassifyBounded(string operation, in AobBo } } + /// Decides what a bounded scan whose session could not be created means, by creation status. + /// The public Client operation name. + /// The SDK's session creation status. + /// The failure, or the reason of the fallback (reported only when it cannot run). + /// + /// for every status after which CheatEngine.SDK holds no MemScan + /// object (an absent or failing factory, an absent, invalid or aliased result, an unqualified target); + /// otherwise. + /// + /// + /// RollbackUnconfirmed is with + /// : a MemScan object Cheat Engine did not destroy is never + /// hidden behind a second scan.

The Fluent README and builder docs said only the bounded route yields null or NotFound, yet a global result list without an address inside the module or range yields them too. The READMEs, the Fluent builder XML docs and the template now state the one scope rule, say that null and NotFound mean a successful scan with no match inside the request, and keep IndeterminateHostResult for a global scan that returns no result list. The qualification harness README names IPatternScanner instead of the deleted IPatternScanOutcomeClient, and the Core README calls the event 1500 count a host result count. --- README.md | 16 ++++++++------- .../Scanning/IPatternScanner.cs | 2 +- libs/CheatEngine.Client.Core/README.md | 2 +- libs/CheatEngine.Client.Fluent/README.md | 20 ++++++++++--------- .../Scanning/AobFirstMatchBuilder.cs | 8 ++++---- .../Scanning/AobManyMatchBuilder.cs | 8 +++++--- .../Scanning/AobScanBuilder.cs | 12 ++++++----- .../Scanning/AobSingleMatchBuilder.cs | 2 +- .../Modules/PluginClientModule.cs | 14 +++++++------ .../content/CheatEngine.Plugin/README.md | 12 +++++++---- .../README.md | 4 ++-- 11 files changed, 57 insertions(+), 43 deletions(-) diff --git a/README.md b/README.md index 54ce033..1a5fb4d 100644 --- a/README.md +++ b/README.md @@ -150,13 +150,15 @@ Address address = client.Patterns client.Memory.At(address + 0x14).Write(999); ``` -`InModule(...)` and `InRange(...)` scope the scan: on a qualified local target Cheat Engine scans only the module -intersected with the range (an exhaustive MemScan that blocks its main thread and cannot be interrupted once started); -on a CEServer or file-as-process target it runs one global `AOBScan` and Core keeps only the addresses inside the module -or range. `Take(n)`, `FirstOrNone()` and `RequireSingle()` bound only how many addresses Core copies; they never stop -Cheat Engine early, and `FirstOrNone()` follows Cheat Engine's unspecified result-list order.

The inspection port calls the CheatEngine.SDK 2.0.0 symbol registry: SymbolRegistry.TryGetName for name lookups and SymbolRegistry.TryRegisterOwned for registrations, whose lease is held behind an internal handle so the Client lease can be tested with a fake. The Client keeps its collision pre-check (the SDK adds none) and its activation-local name reservation. The pre-check, the registration and the registration of the lease with the activation run in one dispatched callback, so a registration never outlives an activation that starts stopping afterwards; if it does stop in between, the registration is released once on the main thread and the failure reports Completed or CleanupUnconfirmed. A registration that the SDK could not hand over (SymbolRegistrationHandoffException) goes through SdkBoundary and is reported CleanupUnconfirmed; the fault path of RegisterSymbol no longer calls CoreFailureFactory directly. The lease is a HostResourceLease and delegates its release to SymbolRegistrationLease.Release, mapped by SdkReleaseOutcomes: StaleRuntime is RefusedRuntimeChanged, CleanupIndeterminate is CleanupUnconfirmed, and the other kinds keep their names. Dispose never throws, a retryable outcome keeps the lease and its name reservation, any other outcome gives the reservation back, and incomplete outcomes reach the deactivation report. Registration statuses without a lease and name lookup statuses are mapped value by value in InspectionMapping, with totality tests. ISymbolRegistrationLease now extends ICheatEngineLease with Name and Address. IDetailedSymbolRegistrationLease and SymbolLeaseReleaseKind are removed, and so is diagnostics event 1401: every release attempt is event 1701 with the operation Inspection.ReleaseSymbol. The getNameFromAddress, registerSymbol and unregisterSymbol bindings leave ClientLuaGlobals, so FrozenLuaGlobals loses three entries and FrozenLuaUsage loses the three generator helpers only they used. SymbolLeaseReleaseKind leaves PendingCharterEnums. The consumed SDK inventory and SdkApiUsage gain the symbol registry members, the observation-only ratchet now also rejects the SDK symbol registry, and SdkInspectionPort.cs joins the Sonar coverage exclusions. --- .github/workflows/sonar.yml | 2 +- .../IDetailedSymbolRegistrationLease.cs | 31 -- .../Inspection/ISymbolRegistrationLease.cs | 40 +- .../Inspection/SymbolLeaseReleaseKind.cs | 33 -- .../PublicAPI.Unshipped.txt | 10 - .../CheatEngine.Client.Abstractions/README.md | 15 +- .../Domains/IInspectionPort.cs | 17 +- .../Domains/ISymbolRegistrationHandle.cs | 21 + .../Domains/InspectionClient.cs | 182 ++++----- .../Domains/InspectionMapping.cs | 162 ++++++++ .../Domains/SdkInspectionPort.cs | 23 +- .../Domains/SymbolRegistrationAttempt.cs | 11 + .../Domains/SymbolRegistrationLease.cs | 179 +++------ .../Infrastructure/ClientLuaGlobals.cs | 11 - .../Infrastructure/ICoreDiagnostics.cs | 20 - libs/CheatEngine.Client.Core/README.md | 11 +- .../ClientCoreDiagnosticsLog.cs | 4 - .../LoggerCoreDiagnostics.cs | 13 - .../Domains/InspectionClientBehaviorTests.cs | 380 ++++++++++++++++-- .../Domains/InspectionMappingTests.cs | 104 +++++ ...olRegistrationLeaseCleanupCoverageTests.cs | 85 ---- .../Domains/SymbolRegistrationLeaseTests.cs | 335 ++++++++------- .../Infrastructure/CoreDiagnosticsTests.cs | 38 +- .../Infrastructure/HostResourceLeaseTests.cs | 5 - .../Infrastructure/TryContractTests.cs | 31 +- tests/CheatEngine.Client.Core.Tests/README.md | 8 +- .../LoggerCoreDiagnosticsTests.cs | 5 +- .../Architecture/ArchitectureRatchetTests.cs | 15 +- .../Architecture/CapabilityRatchetTests.cs | 20 +- .../OutcomeEnumConventionTests.cs | 2 - .../SdkContract/ConsumedSdkSurface.cs | 18 +- .../SdkContract/SdkApiUsage.cs | 10 + 32 files changed, 1149 insertions(+), 692 deletions(-) delete mode 100644 libs/CheatEngine.Client.Abstractions/Inspection/IDetailedSymbolRegistrationLease.cs delete mode 100644 libs/CheatEngine.Client.Abstractions/Inspection/SymbolLeaseReleaseKind.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/ISymbolRegistrationHandle.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/InspectionMapping.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/SymbolRegistrationAttempt.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Domains/InspectionMappingTests.cs delete mode 100644 tests/CheatEngine.Client.Core.Tests/Domains/SymbolRegistrationLeaseCleanupCoverageTests.cs diff --git a/.github/workflows/sonar.yml b/.github/workflows/sonar.yml index 5e3c878..1eecf42 100644 --- a/.github/workflows/sonar.yml +++ b/.github/workflows/sonar.yml @@ -183,7 +183,7 @@ jobs: # (xUnit has no attached Cheat Engine process or Lua state): its lines are untestable, not merely # untested, and its non-SDK branches keep the tests they allow next to it (for example # SdkTableRecordMutationPortTests).

TryResolveAddress and ResolveAddress take the new Client enum AddressResolutionMode (Default = 0, Shallow = 1), which the SDK port turns into AddressResolutionOptions and forwards as Cheat Engine's shallow argument of getAddressSafe. An undefined mode throws ArgumentOutOfRangeException before any work, like any other invalid argument, and never reaches Cheat Engine. TryGetModules takes the process identifier before its out parameters: TryGetModules(request, TargetProcessId? processId, out modules, out failure, cancellationToken). Null still means the selected target. AddressResolutionOptions leaves ApprovedSdkClientTypes, since no public signature uses it any more; Core now constructs it, which the consumed SDK inventory and SdkApiUsage record. AddressResolutionMode joins the OptionEnums allowlist: Default is a valid zero, not Unknown. A test pins that the single positional argument of AddressResolutionOptions binds Shallow on CheatEngine.SDK 2.0, and the inspection tests prove that Shallow reaches the port. The READMEs state that host-side resolution (ResolveHostAddress) and symbol lists (SymbolLists), which CheatEngine.SDK 2.0.0 offers, are not 1.0 goals of the Client. The qualification harness gets the minimal compile fixes for the new signatures. --- README.md | 4 ++ .../Inspection/AddressResolutionMode.cs | 16 +++++++ .../Inspection/IInspectionClient.cs | 29 +++++++++-- .../PublicAPI.Unshipped.txt | 9 ++-- .../CheatEngine.Client.Abstractions/README.md | 4 ++ .../Domains/IInspectionPort.cs | 3 +- .../Domains/InspectionClient.cs | 24 ++++++---- .../Domains/InspectionMapping.cs | 15 +++++- .../Domains/SdkInspectionPort.cs | 6 ++- .../ApprovedSdkClientTypes.cs | 1 - .../Domains/InspectionClientBehaviorTests.cs | 48 +++++++++++++------ .../Domains/InspectionMappingTests.cs | 17 +++++++ .../Infrastructure/CoreDiagnosticsTests.cs | 2 +- .../Infrastructure/TryContractTests.cs | 2 +- .../QualificationScenarios.cs | 8 ++-- .../OutcomeEnumConventionTests.cs | 2 + .../SdkContract/ConsumedSdkSurface.cs | 2 +- .../SdkContract/SdkApiUsage.cs | 1 + 18 files changed, 150 insertions(+), 43 deletions(-) create mode 100644 libs/CheatEngine.Client.Abstractions/Inspection/AddressResolutionMode.cs diff --git a/README.md b/README.md index 1a5fb4d..ab4baab 100644 --- a/README.md +++ b/README.md @@ -269,6 +269,10 @@ pausing, resuming or creating a process, and attaching to the foreground process a process.

The table mutation port calls the CheatEngine.SDK 2.0.0 commands AddressListMutations.Delete, SetParent and SetActive, which resolve the record by identifier in the current list, refuse while a table file loads on the calling thread or after the Lua runtime changed, and report how far they got. SetParent always passes the Client's explicit MemoryRecordParentTraversalLimit of 4096 records. The rollback of a failed creation deletes the created record once through AddressListMutations.Delete with its identifier; a delete that does not complete, faults, or cannot be attempted because the identifier was unreadable stays CleanupUnconfirmed. Every port result is now copied in the SDK's own vocabulary (MemoryRecordMutationEffect and MemoryRecordMutationProblem, or the MemoryRecordActivationOutcomeKind of an activation). The Client's own create and select steps, which have no AddressListMutations command, report theirs in the same vocabulary. The new internal TableMapping classifies them value by value: - TableLoadInProgress is InvalidState; - RuntimeIdentityChanged is RuntimeChanged; - CycleDetected and SelfParent are OperationRejected; - TraversalLimitReached is ResultLimitExceeded; - ParentNotFound and RecordNotFound are NotFound; - LuaFailure is LuaError; - InvalidResult is InvalidHostResult; - AddressListUnavailable and GlobalUnavailable are CapabilityUnavailable; - Uninitialized, None on an incomplete mutation, and any value this Client does not know are IndeterminateHostResult with an Unknown host effect. NotAttempted is NotStarted, Completed is Completed (the command completed and the record could not be copied afterwards, which is never merged with the command) and Indeterminate is Started. An activation maps its kind: Applied and Unchanged succeed with the record copied after the command; RefusedByHost is OperationRejected; Indeterminate is IndeterminateHostResult; NotAttempted takes the kind of its problem with NotStarted; Unknown fails closed. A refusal by the host reports Started, not NotApplied: CheatEngine.SDK reports its effect as Unknown and documents that the refusal may have applied part of its effects, so nothing establishes that nothing was applied. A pending asynchronous activation stays IndeterminateHostResult with Started until the record snapshot can report IsAsyncProcessing. TableParentRelationshipGuard, ParentChainStep and ParentChainStepKind, the raw Parent read, the Client's activation algorithm with its raw Active and AsyncProcessing reads and writes, the raw Parent write, the "destroy" method call and the port's own Lua admission are deleted. FrozenLuaUsage loses the eight SdkTableRecordMutationPort entries; the consumed SDK inventory and SdkApiUsage record the new commands and drop the raw members. The mutation tests run the Tables client over a fake mutation port for every problem and activation kind, the mapping tests prove totality over the three SDK enums, the production port is checked against the real SDK without a Lua runtime, and the static binding contract test now also exercises AddressListMutations.Delete. ITableClient and the READMEs describe the new refusals and effects. --- .../CheatEngine.Client.Abstractions/README.md | 12 +- .../Tables/ITableClient.cs | 32 +- .../Domains/ITableRecordMutationPort.cs | 18 +- .../Domains/ParentChainStep.cs | 16 - .../Domains/ParentChainStepKind.cs | 9 - .../Domains/SdkTableRecordMutationPort.cs | 304 +++------- .../Domains/TableActivationObservation.cs | 34 ++ .../Domains/TableClient.cs | 139 ++--- .../Domains/TableMapping.cs | 278 ++++++++++ .../Domains/TableParentRelationshipGuard.cs | 40 -- .../Domains/TableRecordActivation.cs | 127 ----- .../Domains/TableRecordCreation.cs | 14 +- .../Domains/TableRecordMutationOutcome.cs | 61 ++ .../Domains/TableRecordMutationStatus.cs | 14 - libs/CheatEngine.Client.Core/README.md | 8 +- ...SdkTableRecordMutationPortCoverageTests.cs | 26 - .../SdkTableRecordMutationPortTests.cs | 36 +- .../Domains/TableClientCoverageTests.cs | 14 +- .../Domains/TableClientGenerationTests.cs | 16 +- .../Domains/TableClientMutationTests.cs | 523 ++++++++---------- .../Domains/TableMappingTests.cs | 147 +++++ .../Infrastructure/CoreDiagnosticsTests.cs | 16 +- .../Infrastructure/TryContractTests.cs | 15 +- .../Architecture/ArchitectureRatchetTests.cs | 31 -- .../SdkContract/ConsumedSdkSurface.cs | 22 +- .../SdkContract/SdkApiUsage.cs | 22 +- 26 files changed, 1003 insertions(+), 971 deletions(-) delete mode 100644 libs/CheatEngine.Client.Core/Domains/ParentChainStep.cs delete mode 100644 libs/CheatEngine.Client.Core/Domains/ParentChainStepKind.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/TableActivationObservation.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/TableMapping.cs delete mode 100644 libs/CheatEngine.Client.Core/Domains/TableParentRelationshipGuard.cs delete mode 100644 libs/CheatEngine.Client.Core/Domains/TableRecordActivation.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/TableRecordMutationOutcome.cs delete mode 100644 libs/CheatEngine.Client.Core/Domains/TableRecordMutationStatus.cs delete mode 100644 tests/CheatEngine.Client.Core.Tests/Domains/SdkTableRecordMutationPortCoverageTests.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Domains/TableMappingTests.cs diff --git a/libs/CheatEngine.Client.Abstractions/README.md b/libs/CheatEngine.Client.Abstractions/README.md index af26f7c..b569901 100644 --- a/libs/CheatEngine.Client.Abstractions/README.md +++ b/libs/CheatEngine.Client.Abstractions/README.md @@ -313,8 +313,14 @@ Loads made outside this activation are not detected. `ITableClient.TrySetActive` reports what Cheat Engine did: already in the requested state (success, the setter is not called), applied (success), refused by an activation callback, script or record type (`OperationRejected`, `Started`, with the post-change snapshot), pending asynchronous activation (`IndeterminateHostResult`, `Started`) or indeterminate -(`InvalidHostResult`, `Unknown`).

The AllowedTableRoots policy is unchanged and still refuses a path before any Cheat Engine call, with NotStarted. While a load runs, the SDK refuses address-list mutations issued from the same thread (a script of the table being loaded) with TableLoadInProgress, which the previous commit maps to InvalidState. A dispatched load still advances the table generation whatever its result. TableMapping classifies every LuaOperationStatusKind of a load or save: Success succeeds; GlobalUnavailable is CapabilityUnavailable and StackUnavailable is LuaError, both NotStarted; LuaFailure is LuaError with Started, since a load may have applied part of the table and of its scripts and a save may have written part of the file; NilResult, InvalidResult, MissingResult and ResultCapacityExceeded are InvalidHostResult with Started, because neither global declares a result; Unknown and any value this Client does not know fail closed as IndeterminateHostResult with Unknown. Failure messages name the action, never the path. The loadTable and saveTable bindings are gone, and ClientLuaGlobals.cs with them: the Client binds no Cheat Engine global itself any more. FrozenLuaGlobals is empty and FrozenLuaGlobalsStaysEmpty keeps it so; any [LuaGlobal] in a Client assembly now fails the ratchet. The ten entries of generated binding code leave FrozenLuaUsage, which now holds exactly two owners: UnsafeLuaClient (Permanent) and the TableClient CEObject::TryGetProperty read of Count, awaiting "no MemoryRecord child-count getter in CheatEngine.SDK 2.0.0". The capability ratchet drops its ClientLuaGlobals scan; observation-only types must still reach neither CheatTableFiles nor, now, AddressListMutations (Q45). The consumed SDK inventory and SdkApiUsage record CheatTableFiles and drop the generated-binding helpers. The file port moves to its own SdkTableFilePort.cs. It and SdkTableRecordLookupPort.cs, both SDK production adapters that no hosted test can reach, join the Sonar coverage exclusions. Tests cover the totality of the status mapping, a failed and a faulted load that still advance the generation, the save statuses, and a save path refused before any host call. The static binding contract test now exercises CheatTableFiles.TryLoad. --- .github/workflows/sonar.yml | 2 +- .../CheatEngine.Client.Abstractions/README.md | 2 +- .../Tables/ITableClient.cs | 19 ++- .../Domains/ITableFilePort.cs | 32 +---- .../Domains/SdkTableFilePort.cs | 33 +++++ .../Domains/TableClient.cs | 51 ++++---- .../Domains/TableMapping.cs | 108 +++++++++++++++- .../Infrastructure/ClientLuaGlobals.cs | 18 --- libs/CheatEngine.Client.Core/README.md | 9 +- .../Domains/TableClientGenerationTests.cs | 76 ++++++++++-- .../Domains/TableMappingTests.cs | 58 ++++++++- .../Infrastructure/CoreDiagnosticsTests.cs | 6 +- .../Infrastructure/TryContractTests.cs | 2 +- .../Architecture/ArchitectureRatchetTests.cs | 115 ++++-------------- .../Architecture/CapabilityRatchetTests.cs | 51 ++------ .../SdkContract/ConsumedSdkSurface.cs | 19 +-- .../SdkContract/SdkApiUsage.cs | 26 ++-- 17 files changed, 376 insertions(+), 251 deletions(-) create mode 100644 libs/CheatEngine.Client.Core/Domains/SdkTableFilePort.cs delete mode 100644 libs/CheatEngine.Client.Core/Infrastructure/ClientLuaGlobals.cs diff --git a/.github/workflows/sonar.yml b/.github/workflows/sonar.yml index 1eecf42..e837050 100644 --- a/.github/workflows/sonar.yml +++ b/.github/workflows/sonar.yml @@ -183,7 +183,7 @@ jobs: # (xUnit has no attached Cheat Engine process or Lua state): its lines are untestable, not merely # untested, and its non-SDK branches keep the tests they allow next to it (for example # SdkTableRecordMutationPortTests).

The raw Active read is gone. Only the child count still reads Cheat Engine's Count property, the registered AwaitingSdkPrimitive entry: the SDK has no child-count getter and TryGetChild cannot tell a missing child from a failed read, so ChildCount keeps that read for its precision (A3). The public snapshot shapes change before 1.0: - MemoryRecordStateSnapshot gains IsAsync and IsAsyncProcessing and keeps CurrentAddress, IsActive and ChildCount; its constructor takes both new facts as optional trailing arguments. - MemoryRecordContentSnapshot gains Script (null when Cheat Engine returns no script text, which is the case of any record that is not an Auto Assembler script) and OffsetCount (0 for a plain address, never negative). - MemoryRecordSnapshot drops its seven flattened copies (Description, AddressExpression, Value, VariableType, CurrentAddress, IsActive and ChildCount); every field lives once, in Content or State. - ITableClient.TrySelect becomes TrySelectRecord, the Try form of the existing SelectRecord. - ITableClient.GetCurrent and TryGetCurrent become GetRecordCount and TryGetRecordCount, which return the number of top-level records as an int; an unavailable Address List is now CapabilityUnavailable, like every lookup. GetSnapshot keeps the records, and AddressTableSnapshot loses its count-only constructor, so a table snapshot always holds the records it counts. A pending asynchronous activation is now a success, as planned: the record copied after the command reports IsAsyncProcessing, and a later snapshot observes its final state. A pending activation whose record could not be copied is InvalidHostResult with Started. A hierarchy copy reads TryGetChild(i) for every i below the reported child count; a child Cheat Engine does not return is now reported at its position, with the record identifier and the count, instead of as a generic contract failure. The template counts the Address List records with TryGetRecordCount, the qualification harness reads the record description from Content, and the READMEs describe the pending activation and the getters. The consumed SDK inventory and SdkApiUsage record the new getters; the ratchet reason of the Count read no longer mentions the Active read. --- .../PublicAPI.Unshipped.txt | 22 +--

When the lease cannot join, nothing owns the registration, so it is released once, on the main thread, and the failure reports what that release established (Completed or CleanupUnconfirmed). That compensation only ran for a Client lifecycle exception. The activation's resource registry can also refuse the lease with an ObjectDisposedException: the activation is still current, but its resources were already drained, for example by a Dispose on another thread between the lifecycle check and the registry add. The fault then left RegisterOnMainThread, SdkBoundary reported it as an SDK fault with an Unknown effect, and the Cheat Engine registration and the SDK coordinator's lease stayed behind with no owner. Any exception from the lease registration now takes the compensation path: the registration is released once through its handle and the failure is translated with the effect of that release. A test drains the activation's resources during the registration and checks the single release, InvalidState and Completed.

Its parent-chain read was the only caller of LuaAdmission.Acquire, and so the only producer of LuaAdmissionRefusedException. The TryContractTests theory that injected that carrier through a fake port therefore covered a path production no longer takes. It still claimed that a refused admission inside Tables.SetParent is never a rejection. In production an AddressListMutations command acquires its admission itself and raises a plain InvalidOperationException when it is refused.

The identifiers they would resolve are being replaced. Delete, parent assignment and activation therefore fail with InvalidState and NotStarted during a trusted load, but creation, update and selection have no SDK command and still ran. A creation with a parent during a load could leave an orphan record. The record was created and initialized through the typed MemoryRecord setters, which the SDK does not refuse. Its parent assignment was then refused, and so was the rollback delete. The call returned CleanupUnconfirmed with the new record left in the table being loaded. The SDK's load flag is internal, so TableClient keeps its own depth of trusted loads. It is raised around the dispatched ITableFilePort.TryLoad call and lowered in the same finally block that advances the table generation. It is read and written only inside dispatched callbacks, on Cheat Engine's main thread, where every load runs. A creation, update or selection whose callback runs inside a load is refused before any Cheat Engine call, as NotAttempted(TableLoadInProgress): InvalidState with NotStarted, and nothing to roll back. The shared message now says the Address List was not changed, which also fits a refused creation. Tests run each of the three operations, and a creation under a parent handed out before the load, from inside a trusted load. They check the refusal, that the mutation port is never reached, and that the refusal ends with the load, including a faulted load. ITableClient, the Abstractions README (the paragraph and the Tables row) and the Core README describe the refusal. --- .../CheatEngine.Client.Abstractions/README.md | 10 +- .../Tables/ITableClient.cs | 17 ++-- .../Domains/TableClient.cs | 39 +++++++- .../Domains/TableMapping.cs | 2 +- libs/CheatEngine.Client.Core/README.md | 4 +- .../Domains/TableClientGenerationTests.cs | 91 +++++++++++++++++++ 6 files changed, 148 insertions(+), 15 deletions(-) diff --git a/libs/CheatEngine.Client.Abstractions/README.md b/libs/CheatEngine.Client.Abstractions/README.md index 195e192..4c76567 100644 --- a/libs/CheatEngine.Client.Abstractions/README.md +++ b/libs/CheatEngine.Client.Abstractions/README.md @@ -316,9 +316,11 @@ called), applied (success), a pending asynchronous activation (success; the snap (`OperationRejected`, `Started`, with the post-change snapshot) or indeterminate (`IndeterminateHostResult`, `Started`).

That getter returns false both when Cheat Engine returns no script text and when the read fails with a Lua error or a non-string result. The snapshot copies both as null, and unlike the other fields a failed Script read does not fail the snapshot. The property documentation only named the first case, so a null Script read as proof that the record has no script. The Client cannot fail the snapshot on that read instead. Most records have no script, and it is not established that Cheat Engine always returns script text for an Auto Assembler record. Deriving the answer from the record type could then fail a whole table snapshot because of one record. The Script remarks now state that null also covers a failed read and does not prove that an Auto Assembler record has no script. TableClient.TrySnapshot explains why the read cannot fail the snapshot. The Core README records the gap next to the child count: a getter that tells no script from a failed read is awaited from the SDK. Nothing in the behaviour changes. --- .../Tables/MemoryRecordContentSnapshot.cs | 5 ++++- libs/CheatEngine.Client.Core/Domains/TableClient.cs | 4 +++- libs/CheatEngine.Client.Core/README.md | 4 +++- 3 files changed, 10 insertions(+), 3 deletions(-) diff --git a/libs/CheatEngine.Client.Abstractions/Tables/MemoryRecordContentSnapshot.cs b/libs/CheatEngine.Client.Abstractions/Tables/MemoryRecordContentSnapshot.cs index 1134251..9959a8f 100644 --- a/libs/CheatEngine.Client.Abstractions/Tables/MemoryRecordContentSnapshot.cs +++ b/libs/CheatEngine.Client.Abstractions/Tables/MemoryRecordContentSnapshot.cs @@ -60,7 +60,10 @@ public VariableType VariableType /// Gets the Auto Assembler script of the record (Cheat Engine's Script property). /// /// when Cheat Engine returned no script text, which is the case of a record that is not an - /// Auto Assembler script. + /// Auto Assembler script, or when the script could not be read: CheatEngine.SDK reports a failed read of + /// Script the same way as a record without one. therefore does not prove that an + /// Auto Assembler record has no script, and unlike the other fields a failed Script read does not fail the + /// snapshot. /// public string?

No test ran that walk. The test tagged as Q34 evidence only called the static message factory ChildUnavailableFailure, because TableClient walked CheatEngine.SDK MemoryRecord values directly and no hosted test can build one. The walk now reads records through two internal interfaces: ITableHierarchyPort resolves the root and ITableHierarchyRecord gives a record's snapshot and its children by position. SdkTableRecordLookupPort implements the port over the typed MemoryRecord getters, with the same lookup as before, and TableClient takes an optional hierarchy port. The walk, its limits and its failures are unchanged, and ChildUnavailableFailure becomes private. The formatter-only test and its Q34 trait are gone. Two tests now run the walk over fake records: - A record that reports three children but returns no child at position 1 fails with InvalidHostResult and the message that names record 12, position 1 and the count 3. Position 2 is never read. - A nested hierarchy is copied in order, and each record is read at exactly the positions below its count. The mapping test TableFileFailuresNameTheActionAndNeverThePath claimed a path check that TableMapping cannot fail, since it never receives the path. It becomes TableFileFailuresNameOnlyTheirOwnAction, uses each action's own operation name and drops the path assertion. The save status test now asserts through TableClient that the message never contains the path, as the load test already did. --- .../Domains/ITableHierarchyPort.cs | 40 ++++++ .../Domains/SdkTableRecordLookupPort.cs | 43 ++++++- .../Domains/TableClient.cs | 19 +-- .../Domains/TableClientGenerationTests.cs | 1 + .../Domains/TableClientLookupTests.cs | 115 +++++++++++++++++- .../Domains/TableMappingTests.cs | 11 +- 6 files changed, 207 insertions(+), 22 deletions(-) create mode 100644 libs/CheatEngine.Client.Core/Domains/ITableHierarchyPort.cs diff --git a/libs/CheatEngine.Client.Core/Domains/ITableHierarchyPort.cs b/libs/CheatEngine.Client.Core/Domains/ITableHierarchyPort.cs new file mode 100644 index 0000000..7843ca4 --- /dev/null +++ b/libs/CheatEngine.Client.Core/Domains/ITableHierarchyPort.cs @@ -0,0 +1,40 @@ +using System.Diagnostics.CodeAnalysis; + +using CheatEngine.Client.Tables; +using CheatEngine.SDK.Engine.AddressList; + +namespace CheatEngine.Client.Core.Domains; + +/// +/// Resolves the root of a hierarchy copy, so that 's walk of each record's children by +/// position is testable without Cheat Engine.

Release goes through ReleaseWithOutcome, which writes a global only while it still holds the value the module installed (F12, Q16). The per-module SDK port is gone: no CreateRef pin, no RawEquals, no nil clear, no reserved __CheatEngineLua prefix, and no emitted "ADR-01 ... Removal: SDK 2.0" comment. A module part is now Descriptor, Register, Unregister and one field. Once per assembly the generator emits an internal registrar, which maps the SDK admission status, registration result and release kind to the Client vocabulary, and a separate SDK adapter, the only generated code that calls the SDK. The EndToEnd harness replaces that adapter file with a double of the SDK registration set, because LuaRegistrationLease has no public constructor; the module and the registrar run unchanged, and the mappings are proven total on the real registrar. GeneratedLuaSurfaceRatchetTests becomes an exact allowlist of the SDK-imposed registration API: the admission, ReleaseWithOutcome, and the getters of the registration result, its failure and the release outcome and its failures. This is the SDK-imposed admission growth the ratchet protocol allows for this lot; the list may only shrink. The SDK reports counts and failed names, not a status per export, so the public outcome moves with the generator instead of in the next commit: LuaModuleReleaseOutcome carries the module name, a LeaseReleaseKind, the SDK counts and FailedExports, with public factories, and LuaModuleReleaseKind, LuaExportReleaseStatus and LuaExportReleaseOutcome are deleted. ILuaModule folds to Descriptor, Register and a LuaModuleReleaseOutcome Unregister; IDescribedLuaModule and IOwnershipAwareLuaModule are deleted. LuaClient therefore reserves the names of every module, keeps the failure a CheatEngineOperationException carries, and classifies any other registration fault through SdkBoundary. SDK Stale maps to RefusedRuntimeChanged, as planned. The SDK counts it complete only because no cleanup call failed; it reports every entry as remaining, and after a re-enable on the same Lua state the earlier functions stay in _G. ExternallyRemoved would claim nothing remains. source-generators/ enters the SdkPinTests prose scope; the generator README is rewritten for the SDK leases and names only the pin. --- README.md | 6 +- .../Lua/CheatEngineLuaModuleAttribute.cs | 15 +- .../Lua/IDescribedLuaModule.cs | 24 - .../Lua/ILuaModule.cs | 75 ++- .../Lua/IOwnershipAwareLuaModule.cs | 41 -- .../Lua/LuaExportReleaseOutcome.cs | 37 -- .../Lua/LuaExportReleaseStatus.cs | 38 -- .../Lua/LuaModuleReleaseKind.cs | 28 - .../Lua/LuaModuleReleaseOutcome.cs | 289 ++++++--- .../PublicAPI.Unshipped.txt | 47 +- .../CheatEngine.Client.Abstractions/README.md | 33 +- .../Domains/LuaClient.cs | 126 ++-- .../Domains/LuaModuleLease.cs | 16 +- .../CheatEngineClientBuilder.cs | 12 +- .../LuaModuleLifecycle.cs | 4 +- .../CheatEngineLuaGenerator.cs | 17 +- .../ModuleEmitter.cs | 583 +---------------- .../ModuleParser.cs | 16 +- .../README.md | 196 +++--- .../RegistrarEmitter.cs | 421 ++++++++++++ src/CheatEngine.Client/README.md | 6 +- .../Lua/LuaContractTests.cs | 5 - .../Lua/LuaModuleReleaseOutcomeTests.cs | 184 +++--- tests/CheatEngine.Client.AotProbe/Program.cs | 2 +- .../Lua/LuaModuleRegistrationTests.cs | 93 ++- ...eClientServiceCollectionExtensionsTests.cs | 10 +- .../README.md | 6 +- .../Packaging/SdkPinTests.cs | 1 + .../GeneratedLuaSurfaceRatchetTests.cs | 154 +++-- .../CheatEngineLuaGeneratorTests.cs | 6 +- .../Diagnostics/ModuleShapeDiagnosticTests.cs | 11 +- .../EndToEnd/FakeLuaGlobals.cs | 398 +++++++----- .../GeneratedRegistrarMappingTests.cs | 89 +++ .../LuaModuleOwnershipEndToEndTests.cs | 610 +++++++----------- .../EndToEnd/ModuleHarness.cs | 207 +++--- .../README.md | 9 +- .../SdkPort/GeneratedSdkPort.cs | 141 ---- .../SdkPort/SdkPortDecisionTests.cs | 320 --------- .../SdkPort/SdkPortPaths.cs | 294 --------- .../SdkPort/SdkPortStackDisciplineTests.cs | 74 --- .../Snapshots/ModuleSnapshots.cs | 460 +------------ .../Validation/IdentifierStabilityTests.cs | 25 +- .../Validation/ModuleContractTests.cs | 61 +- 43 files changed, 1936 insertions(+), 3254 deletions(-) delete mode 100644 libs/CheatEngine.Client.Abstractions/Lua/IDescribedLuaModule.cs delete mode 100644 libs/CheatEngine.Client.Abstractions/Lua/IOwnershipAwareLuaModule.cs delete mode 100644 libs/CheatEngine.Client.Abstractions/Lua/LuaExportReleaseOutcome.cs delete mode 100644 libs/CheatEngine.Client.Abstractions/Lua/LuaExportReleaseStatus.cs delete mode 100644 libs/CheatEngine.Client.Abstractions/Lua/LuaModuleReleaseKind.cs create mode 100644 source-generators/CheatEngine.Client.SourceGenerators.Lua/RegistrarEmitter.cs create mode 100644 tests/CheatEngine.Client.SourceGenerators.Lua.Tests/EndToEnd/GeneratedRegistrarMappingTests.cs delete mode 100644 tests/CheatEngine.Client.SourceGenerators.Lua.Tests/SdkPort/GeneratedSdkPort.cs delete mode 100644 tests/CheatEngine.Client.SourceGenerators.Lua.Tests/SdkPort/SdkPortDecisionTests.cs delete mode 100644 tests/CheatEngine.Client.SourceGenerators.Lua.Tests/SdkPort/SdkPortPaths.cs delete mode 100644 tests/CheatEngine.Client.SourceGenerators.Lua.Tests/SdkPort/SdkPortStackDisciplineTests.cs diff --git a/README.md b/README.md index ab4baab..5ef49bd 100644 --- a/README.md +++ b/README.md @@ -296,9 +296,9 @@ dependency of `CheatEngine.Client.Extensions.DependencyInjection`. - new enum values.

IsReleased now comes from ICheatEngineLease. LuaModuleLease moves onto HostResourceLease, so the release runs on Cheat Engine's main thread, is logged as Lua.UnregisterModule, and no longer throws an AggregateException from Dispose. The new LuaModuleReleaseMapping keeps the kind the module reported and derives the host effect with the SdkReleaseOutcomes rule (Completed, Started, NotStarted, Unknown); it is total over LeaseReleaseKind and fails closed. A CleanupUnavailable or Unknown outcome keeps the lease active and tracked, so the activation cleanup retries it. A partial release or a registration of an earlier Lua attachment ends the lease but keeps it tracked, so the deactivation report carries it. An exception thrown by the module is an unconfirmed cleanup that is never retried. The name reservation ends with the lease. The lease no longer skips its release when the activation is not current: the dispatcher refuses it, and the outcome is CleanupUnavailable instead of a silent release. The first commit of this lot already moved the outcome shape, the ILuaModule fold and the deletions that the plan listed here, because the generator could only report what the SDK observes; this commit keeps the lease side. --- .../Lua/ILuaModuleLease.cs | 28 ++- .../PublicAPI.Unshipped.txt | 2 +- .../CheatEngine.Client.Abstractions/README.md | 8 +- .../Domains/LuaClient.cs | 18 +- .../Domains/LuaModuleLease.cs | 211 ++++++++++-------- .../Domains/LuaModuleReleaseMapping.cs | 42 ++++ libs/CheatEngine.Client.Core/README.md | 5 +- .../Lua/LuaModuleRegistrationTests.cs | 150 +++++++++---- .../Lua/LuaModuleReleaseMappingTests.cs | 48 ++++ ...eClientServiceCollectionExtensionsTests.cs | 15 ++ 10 files changed, 364 insertions(+), 163 deletions(-) create mode 100644 libs/CheatEngine.Client.Core/Domains/LuaModuleReleaseMapping.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Lua/LuaModuleReleaseMappingTests.cs diff --git a/libs/CheatEngine.Client.Abstractions/Lua/ILuaModuleLease.cs b/libs/CheatEngine.Client.Abstractions/Lua/ILuaModuleLease.cs index 641269a..bf42121 100644 --- a/libs/CheatEngine.Client.Abstractions/Lua/ILuaModuleLease.cs +++ b/libs/CheatEngine.Client.Abstractions/Lua/ILuaModuleLease.cs @@ -1,3 +1,5 @@ +using CheatEngine.Client.Results; + namespace CheatEngine.Client.Lua; /// Owns one explicit Lua module registration in a single Cheat Engine client epoch. @@ -7,12 +9,18 @@ namespace CheatEngine.Client.Lua; /// members to it, so implement it only in a test double. /// /// -/// Disposing the lease unregisters its module synchronously on Cheat Engine's main thread.

It now has one pair, TryExecute/Execute(in TOperation, ...), constrained to ILuaOperation only: a readonly value operation is passed by reference and called through a constrained call, never boxed, and a class operation takes the same path. The default interface methods and the pragma are gone, so PendingOverloadSuppressions is now empty. TryRegisterModule/RegisterModule and IUnsafeLuaClient do not change. C# cannot infer TResult from the operation alone, so the generator now emits, next to each [CheatEngineLuaOperation] factory, an Execute and a TryExecute extension method on ILuaClient for that operation type; a call reads client.Execute(operation). A generator test compiles such a call without type arguments. LuaClient keeps a single dispatch path; its null check on the unconstrained operation type does not box, and ScalarLuaResultMapperDoesNotAllocateAfterWarmup stays green. The test doubles and the call sites that relied on the removed overloads now pass the type arguments. --- .../Lua/ILuaClient.cs | 58 +++------ .../PublicAPI.Unshipped.txt | 6 +- .../Domains/LuaClient.cs | 118 ++---------------- .../OperationEmitter.cs | 55 +++++++- .../README.md | 5 +- .../Lua/LuaContractTests.cs | 46 +++++-- .../Infrastructure/TryContractTests.cs | 11 +- .../Lua/LuaClientTests.cs | 8 +- ...eClientServiceCollectionExtensionsTests.cs | 13 +- .../Packaging/PublicApiFileTests.cs | 5 +- .../CheatEngineLuaGeneratorTests.cs | 37 ++++++ 11 files changed, 183 insertions(+), 179 deletions(-) diff --git a/libs/CheatEngine.Client.Abstractions/Lua/ILuaClient.cs b/libs/CheatEngine.Client.Abstractions/Lua/ILuaClient.cs index b0f6969..4897e3b 100644 --- a/libs/CheatEngine.Client.Abstractions/Lua/ILuaClient.cs +++ b/libs/CheatEngine.Client.Abstractions/Lua/ILuaClient.cs @@ -6,8 +6,16 @@ namespace CheatEngine.Client.Lua; /// Executes typed Lua operations without exposing a Lua state or CE object handle. /// -/// Call-only.

RealSdkGeneratorCompositionTests now loads CheatEngine.SDK.SourceGenerators.LuaBindings.dll and its Shared.dll from $(NuGetPackageRoot)cheatengine.sdk/$(CheatEngineSdkVersion)/ analyzers/dotnet/cs, passed by the test project as AssemblyMetadata with the pin, never a user path. It runs that generator next to the Client generator on a module and on throwing and Try operations, and requires an error-free compilation. It also checks that the module publishes through LuaRegistrationSet and never calls the legacy Register/UnregisterLuaFunctions pair, and that integer results are read with the SDK marshallers that refuse a float at or above 2^53. The two runtime changes behind CRIT-07 are classified and tested. A refused integer result reaches a generated operation as a LuaException with status LUA_OK (throwing form) or as false (Try form); both are reported as a LuaError failure, and no SDK exception leaves TryExecute (OperationRefusalEndToEndTests). The SDK wraps each published thunk in a closure that captures the attachment and Lua state identity, so a function a script kept after disable raises a Lua error; the EndToEnd double models this and the generator README states it. The generator README gains the CheatEngine.SDK composition facts, a "What to do" column for every CECLUA diagnostic, and the deferral of LuaOptional past 1.0. The PluginCollision fixture registers its generated module through ILuaClient.TryRegisterModule, so the expected enable failure carries the Client classification (OperationRejected, NotApplied); the Coexistence README states that result and describes Q16 in terms of the SDK registration lease. --- .../README.md | 59 ++++-- .../CoexistencePluginCollision.cs | 27 ++- .../PluginCollision/README.md | 6 + .../README.md | 18 +- ...e.Client.SourceGenerators.Lua.Tests.csproj | 11 ++ .../RealSdkGeneratorCompositionTests.cs | 187 ++++++++++++++++++ .../EndToEnd/OperationRefusalEndToEndTests.cs | 125 ++++++++++++ .../Infrastructure/GeneratorRun.cs | 13 +- .../README.md | 1 + 9 files changed, 417 insertions(+), 30 deletions(-) create mode 100644 tests/CheatEngine.Client.SourceGenerators.Lua.Tests/Composition/RealSdkGeneratorCompositionTests.cs create mode 100644 tests/CheatEngine.Client.SourceGenerators.Lua.Tests/EndToEnd/OperationRefusalEndToEndTests.cs diff --git a/source-generators/CheatEngine.Client.SourceGenerators.Lua/README.md b/source-generators/CheatEngine.Client.SourceGenerators.Lua/README.md index 5a531f2..762ff58 100644 --- a/source-generators/CheatEngine.Client.SourceGenerators.Lua/README.md +++ b/source-generators/CheatEngine.Client.SourceGenerators.Lua/README.md @@ -86,6 +86,26 @@ admission (`LuaRuntime.TryAcquireOperationWithOutcome`, `LuaRuntimeOperation.Sta admitted operation is only passed to the SDK: generated code never reads or writes the Lua stack.

The EndToEnd replacement adapter re-implemented both, so those tests exercised a copy of the logic and never the generated code. The adapter now exposes one SDK call per member and no decision: TryAdmit, EndOperation, Publish, Release(lease, state) and ReleaseStale. The registrar admits and ends the operation, releases the earlier and the residual lease, and consumes the module's lease. Its SDK surface is unchanged, so the GeneratedLuaSurfaceRatchetTests allowlist stays the same. The test adapter now only forwards each call to FakeLuaGlobals. The double counts admitted operations, refuses Lua work outside one, and records the module's bindings registration, which the harness bindings now report instead of being skipped. New EndToEnd tests check that each call runs in one admitted operation that it ends, and that the module registers with RejectExisting. The test of a function kept after disable is removed: it only called the double. The SDK closure that captures the attachment runs inside the SDK registration set, so its evidence is the composition test and the Q16 host scenario, as the generator and test READMEs now say. --- .../README.md | 34 +-- .../RegistrarEmitter.cs | 206 +++++++++--------- .../EndToEnd/FakeLuaGlobals.cs | 110 ++++++---- .../LuaModuleOwnershipEndToEndTests.cs | 49 +++-- .../EndToEnd/ModuleHarness.cs | 85 ++++---- .../README.md | 2 +- 6 files changed, 271 insertions(+), 215 deletions(-) diff --git a/source-generators/CheatEngine.Client.SourceGenerators.Lua/README.md b/source-generators/CheatEngine.Client.SourceGenerators.Lua/README.md index 762ff58..318a54f 100644 --- a/source-generators/CheatEngine.Client.SourceGenerators.Lua/README.md +++ b/source-generators/CheatEngine.Client.SourceGenerators.Lua/README.md @@ -30,16 +30,21 @@ For each valid module, one partial part of the module class with three members a Once per assembly that declares a valid module, two internal files in the namespace `CheatEngine.Client.Lua.Generated`: -- `CheatEngineLuaModuleRegistrar` decides.

It then mapped NotAttempted to CleanupUnavailable and an undefined LuaRegistrationReleaseKind, or a PartiallyReleased that names no global, to Unknown. Both are retryable, so the Client lease stayed active and its next release, or the activation cleanup, called Unregister again. That call found no lease and reported AlreadyReleased: a clean release, and the Q43 report never carried the incomplete one. A CheatEngine.SDK 2.x minor that adds a release kind reaches this path, since consumers compile the registrar against [2.0.0,3.0.0). Once the lease is consumed, those results are now CleanupUnconfirmed: never retried, requiring manual recovery, and reported by the activation cleanup. Every export the release did not report as handled counts as remaining. CleanupUnavailable stays for a refused admission, which keeps the registration. SDK 2.0.0 never returns NotAttempted from a release (it is the value before one), so the plan's NotAttempted -> CleanupUnavailable row no longer applies. An EndToEnd case scripts such a release through the double. A Core case shows that a CleanupUnconfirmed module release ends the Client lease, is not retried, and is reported by the drain. The mapping test also checks that no consumed-lease kind is retryable. The ILuaModule and LuaModuleReleaseOutcome docs said that a refused admission always keeps the registration as CleanupUnavailable. They now say that Detached and ExternalStateReset consume it and report RefusedRuntimeChanged, and they list CleanupUnconfirmed. The generator and Abstractions READMEs match. The IsComplete test of LuaModuleReleaseOutcome now states the expected value for each kind instead of recomputing the implementation's rule. --- .../Lua/ILuaModule.cs | 9 +++- .../Lua/LuaModuleReleaseOutcome.cs | 13 +++--- .../CheatEngine.Client.Abstractions/README.md | 10 +++-- .../README.md | 12 ++--- .../RegistrarEmitter.cs | 45 ++++++++++++------- .../Lua/LuaModuleReleaseOutcomeTests.cs | 28 ++++++------ .../Lua/LuaModuleRegistrationTests.cs | 39 ++++++++++++++++ .../EndToEnd/FakeLuaGlobals.cs | 16 +++++++ .../GeneratedRegistrarMappingTests.cs | 10 ++++- .../LuaModuleOwnershipEndToEndTests.cs | 24 ++++++++++ 10 files changed, 159 insertions(+), 47 deletions(-) diff --git a/libs/CheatEngine.Client.Abstractions/Lua/ILuaModule.cs b/libs/CheatEngine.Client.Abstractions/Lua/ILuaModule.cs index 07b2573..96e9d3c 100644 --- a/libs/CheatEngine.Client.Abstractions/Lua/ILuaModule.cs +++ b/libs/CheatEngine.Client.Abstractions/Lua/ILuaModule.cs @@ -64,8 +64,13 @@ public LuaModuleDescriptor Descriptor /// /// A generated module writes only globals that still hold the value it installed and never overwrites one a /// third party replaced.

The outcome of that release was discarded. When it was PartiallyReleased, a global could still hold the module's own function, and the publication reported it as a collision with a third party ("Lua global 'x' is already defined"), while the partial release was reported nowhere. This path is reachable when an application registers a module instance again while it still owns a lease, for example after a CleanupUnavailable release. The registrar now keeps the earlier release. When it may leave one of the module's globals (PartiallyReleased, or a result outside the documented shape), Register publishes nothing and throws LuaError, or InvalidHostResult for an unrecognized result, with the host effect CleanupUnconfirmed and the release counts. A Stale earlier release still lets the publication run, but a resulting collision now names that release, because the global may be the module's function from an earlier attachment. Two EndToEnd cases cover both paths, and the generator README and the ILuaModule.Register docs describe them. --- .../Lua/ILuaModule.cs | 4 +- .../README.md | 13 +++-- .../RegistrarEmitter.cs | 48 +++++++++++++++++-- .../LuaModuleOwnershipEndToEndTests.cs | 39 +++++++++++++++ 4 files changed, 96 insertions(+), 8 deletions(-) diff --git a/libs/CheatEngine.Client.Abstractions/Lua/ILuaModule.cs b/libs/CheatEngine.Client.Abstractions/Lua/ILuaModule.cs index 96e9d3c..65b26a4 100644 --- a/libs/CheatEngine.Client.Abstractions/Lua/ILuaModule.cs +++ b/libs/CheatEngine.Client.Abstractions/Lua/ILuaModule.cs @@ -47,7 +47,9 @@ public LuaModuleDescriptor Descriptor /// host effect NotStarted), when a global is already defined (OperationRejected, /// NotApplied: nothing was published), or when a protected lookup or publication failed /// (LuaError; NotApplied when the SDK's rollback removed everything it published, - /// CleanupUnconfirmed otherwise). + /// CleanupUnconfirmed otherwise).

The shared-files protocol requires each port lot to add its per-family Try case (AUD-26). The existing TryRegisterModule tests mostly run on a fake dispatcher, which cannot prove the same-instance rethrow rule. TryContractTests now runs TryRegisterModule on the real SdkMainThreadDispatcher: an expired activation throws ActivationExpired before the module runs, a pre-dispatch cancellation is NotStarted, the throwing form raises the cancellation exception of its Try form, and every SDK fault kind that a module's Register throws is classified, with the fault attached, and never crosses TryRegisterModule or RegisterModule. A module could also throw a CheatEngineOperationException that carries the default failure. TryRegisterModule then returned false with a default failure, and RegisterModule turned it into a bare InvalidOperationException. Such a refusal is now an Unknown failure of Lua.RegisterModule with the exception attached, the rule that already applies to a typed operation that fails without a failure.

IValueScanner creates a session through MemoryScanSessions.TryCreateWithOutcome on Cheat Engine's main thread. The session is a HostResourceLease registered with the activation and with its target selection: its release runs ReleaseWithOutcome (found list, then scanner) on the main thread and keeps the worse outcome, when the application releases it, when another process is selected, or before the SDK detaches. An unconfirmed stop of a running scan leaves CleanupUnconfirmed, as on the bounded AOB route. A first or next scan chains Start*Cancellable and WaitForCompletionCancellable in one dispatch; a read copies one page through TryCopyResultsPageCancellable, bounded by ScanResourceLimits.MaximumValueScanPage. The adapter never touches the Scanner or Results handles (CESDK1001) nor TryWaitForCompletion and TryTerminateScan (CESDK5010). Every SDK outcome maps exhaustively, with totality tests: creation statuses, session states, invalidation reasons, cancellation milestones, materialization and termination statuses, and how far a scan got for each memory-scan failure kind. Faults still go through SdkBoundary. Cheat Engine's bounded error text ends the message of a failed scan. The Client owns the request vocabulary: typed ValueScanValue factories, value types, comparisons, first and next requests, long-indexed reads and address-first matches. First scans take the ScanProtectionFilter and ScanAlignment options the AOB lot defines. FirstScanRequest and NextScanRequest leave the approved SDK types, ValueScanSessionState gains Unknown = 0 and leaves PendingCharterEnums, and UnavailableValueScanner and the managed state machine are deleted. The catalog row becomes operational with its experimental id, which the runtime implementation reason and the README label report. The new ClientExperimentalDiagnosticsTests keeps each CECLIENT500x id catalogued with its README anchor, UrlFormat and PublicAPI prefix, and allows NoWarn or pragmas only in Core, DI and tests. The consumed SDK inventories record the scan-session members. --- .github/workflows/sonar.yml | 2 +- README.md | 2 +- RELEASING.md | 6 +- .../ClientExperimentalDiagnostics.cs | 24 + .../ICheatEngineClient.cs | 6 +- .../PublicAPI.Unshipped.txt | 209 ++++-- .../CheatEngine.Client.Abstractions/README.md | 43 +- .../Scanning/IValueScanSession.cs | 123 +++- .../Scanning/IValueScanner.cs | 36 +- .../Scanning/ValueScanComparison.cs | 47 ++ .../Scanning/ValueScanFirstRequest.cs | 214 +++++++ .../Scanning/ValueScanInvalidationKind.cs | 27 + .../Scanning/ValueScanMatch.cs | 34 +- .../Scanning/ValueScanNextRequest.cs | 158 +++++ .../Scanning/ValueScanPage.cs | 32 +- .../Scanning/ValueScanReadRequest.cs | 26 +- .../Scanning/ValueScanSessionState.cs | 43 +- .../Scanning/ValueScanValue.cs | 150 +++++ .../Scanning/ValueScanValueType.cs | 39 ++ .../CheatEngine.Client.Core.csproj | 2 + .../Domains/ClientCapabilityCatalog.cs | 21 +- .../Domains/RuntimeClient.cs | 15 +- .../Domains/ScanResourceLimits.cs | 6 + .../Domains/UnavailableValueScanner.cs | 61 -- .../Domains/ValueScanSessionStateMachine.cs | 85 --- .../Domains/ValueScanning/IValueScanPort.cs | 76 +++ .../Domains/ValueScanning/SdkValueScanPort.cs | 103 +++ .../Domains/ValueScanning/ValueScanMapping.cs | 294 +++++++++ .../ValueScanning/ValueScanRequests.cs | 277 ++++++++ .../Domains/ValueScanning/ValueScanSession.cs | 430 +++++++++++++ .../Domains/ValueScanning/ValueScanner.cs | 126 ++++ libs/CheatEngine.Client.Core/README.md | 7 +- ...ient.Extensions.DependencyInjection.csproj | 2 + ...EngineClientServiceCollectionExtensions.cs | 6 +- libs/CheatEngine.Client.Fluent/README.md | 4 +- .../ApprovedSdkClientTypes.cs | 2 -

00:00:00 2001 From: AriusII Date: Thu, 24 Sep 2026 23:28:01 +0200 Subject: [PATCH 203/321] Add experimental target allocations over SDK regions Compose Client.Allocations as an operational adapter over the CheatEngine.SDK 2.0.0 target allocator, and publish its API as experimental under CECLIENT5002 until the Q30.a receipt exists. IAllocationClient allocates through TargetMemoryAllocator.TryAllocate on Cheat Engine's main thread, with an explicit PAGE_READWRITE or PAGE_EXECUTE_READWRITE protection and an optional preferred address. The allocation is a TargetMemoryLease, a HostResourceLease registered with the activation and with its target selection: its release runs AllocatedRegion.ReleaseWithTargetOutcome on the main thread, when the application releases it, when another process is selected, or before the SDK detaches. The SDK frees it only in the process incarnation and the Lua runtime that made it; otherwise it refuses without any Cheat Engine call (RefusedTargetChanged, RefusedRuntimeChanged), the lease never selects a target again, and RequiresManualRecovery is set. Address, Size and Protection stay readable after the release. A late cancellation or a failed registration releases the new allocation at once and publishes nothing. Every SDK outcome maps exhaustively, with totality tests: the allocation category, the effect through HostEffectMapping, the release through SdkReleaseOutcomes, and the compensation the SDK makes when Cheat Engine allocated but no owner was published. A compensation that is not confirmed reports CleanupUnconfirmed with the address and size in the message. Faults still go through SdkBoundary. The public vocabulary is renamed to avoid the CS0104 clash with the SDK: AllocationRequest(size, protection, preferredAddress) and the option enum AllocationProtection (ReadWrite = 0, ExecuteReadWrite = 1) replace TargetAllocationRequest and TargetAllocationAccess, which leaves PendingCharterEnums; ITargetMemoryLease becomes an ICheatEngineLease. UnavailableAllocationClient is deleted, and only Assembly stays contract-only. The catalog row becomes operational with its experimental id, the READMEs gain the CECLIENT5002 anchor, the capability and Try rows, and note that executable memory needs no opt-in. The consumed SDK inventories record the allocator members, and SdkAllocationPort joins the Sonar coverage exclusions. The AotProbe, the qualification harness and the Coexistence fixture get the compile fix with a local pragma. --- .github/workflows/sonar.yml | 2 +- README.md | 9 +- .../Allocations/AllocationProtection.cs | 30 ++ .../Allocations/AllocationRequest.cs | 70 +++ .../Allocations/IAllocationClient.cs | 40 +- .../Allocations/ITargetMemoryLease.cs | 49 +- .../Allocations/TargetAllocationAccess.cs | 11 - .../Allocations/TargetAllocationRequest.cs | 32 -- .../ClientExperimentalDiagnostics.cs | 3 + .../ICheatEngineClient.cs | 4 +- .../PublicAPI.Unshipped.txt | 48 +- .../CheatEngine.Client.Abstractions/README.md | 37 +- .../CheatEngine.Client.Core.csproj | 4 +- .../Domains/Allocations/AllocationClient.cs | 129 ++++++ .../Domains/Allocations/AllocationMapping.cs | 222 +++++++++ .../Domains/Allocations/IAllocationPort.cs | 45 ++ .../Domains/Allocations/SdkAllocationPort.cs | 80 ++++ .../Domains/Allocations/TargetMemoryLease.cs | 73 +++ .../UnavailableAllocationClient.cs | 37 -- .../Domains/ClientCapabilityCatalog.cs | 7 +- libs/CheatEngine.Client.Core/README.md | 7 +- ...ient.Extensions.DependencyInjection.csproj | 4 +- ...EngineClientServiceCollectionExtensions.cs | 4 +- .../Allocations/AllocationContractsTests.cs | 45 +- ...eatEngine.Client.Abstractions.Tests.csproj | 4 +- .../README.md | 8 +- tests/CheatEngine.Client.AotProbe/Program.cs | 13 +- .../CheatEngine.Client.Core.Tests.csproj | 4 +- .../Allocations/AllocationClientTests.cs | 422 ++++++++++++++++++ .../Allocations/AllocationMappingTests.cs | 195 ++++++++ .../Domains/ClientCapabilityCatalogTests.cs | 6 +- .../Domains/RuntimeClientTests.cs | 13 +- .../UnavailableAdvancedClientsTests.cs | 40 +- .../Infrastructure/TryContractTests.cs | 44 +- tests/CheatEngine.Client.Core.Tests/README.md | 3 + .../TestSupport/FakeAllocationPort.cs | 137 ++++++ ...xtensions.DependencyInjection.Tests.csproj | 4 +- ...eClientServiceCollectionExtensionsTests.cs | 20 +- .../CheatEngine.Client.Fluent.Tests.csproj | 4 +- .../CheatEngine.Client.Hosting.Tests.csproj | 4 +- .../CoexistenceDiagnostics.cs | 5 +- .../QualificationScenarios.cs | 4 +- .../Architecture/CapabilityRatchetTests.cs | 10 +- .../ClientExperimentalDiagnosticsTests.cs | 3 +- .../OutcomeEnumConventionTests.cs | 8 +- .../CheatEngine.Client.Tests.csproj | 4 +- .../SdkContract/ConsumedSdkSurface.cs | 25 ++ .../SdkContract/SdkApiUsage.cs | 17 + 48 files changed, 1761 insertions(+), 228 deletions(-) create mode 100644 libs/CheatEngine.Client.Abstractions/Allocations/AllocationProtection.cs create mode 100644 libs/CheatEngine.Client.Abstractions/Allocations/AllocationRequest.cs delete mode 100644 libs/CheatEngine.Client.Abstractions/Allocations/TargetAllocationAccess.cs delete mode 100644 libs/CheatEngine.Client.Abstractions/Allocations/TargetAllocationRequest.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/Allocations/AllocationClient.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/Allocations/AllocationMapping.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/Allocations/IAllocationPort.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/Allocations/SdkAllocationPort.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/Allocations/TargetMemoryLease.cs delete mode 100644 libs/CheatEngine.Client.Core/Domains/Allocations/UnavailableAllocationClient.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Domains/Allocations/AllocationClientTests.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Domains/Allocations/AllocationMappingTests.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/TestSupport/FakeAllocationPort.cs diff --git a/.github/workflows/sonar.yml b/.github/workflows/sonar.yml index 31e08bb..44b1094 100644 --- a/.github/workflows/sonar.yml +++ b/.github/workflows/sonar.yml @@ -183,7 +183,7 @@ jobs: # (xUnit has no attached Cheat Engine process or Lua state): its lines are untestable, not merely # untested, and its non-SDK branches keep the tests they allow next to it (for example # SdkTableRecordMutationPortTests).

Subject: [PATCH 204/321] Key target-bound leases to the process the SDK bound A new allocation or value-scan session was registered under the current target-selection epoch, which advances only when the Client observes Cheat Engine's selection. After a process was selected in Cheat Engine's own window, a lease bound by CheatEngine.SDK to the new process was keyed to the old epoch, so the next Processes.GetCurrent or Refresh released it while its own target was still selected: the SDK then accepted the release, freeing live memory or destroying a live scan session. ProcessClient now implements an internal ITargetSelectionBinder. In the main-thread callback that created the owner, AllocationClient and ValueScanner record the incarnation the SDK bound it to (AllocatedRegion.TargetIncarnation, the creation outcome's TargetObservation) as an observation of the selection, using the same change rules as a process observation, and register the lease under the epoch this leaves. A change advances the epoch first and releases the earlier selection's leases, which the SDK refuses without any call; the advance is logged after the callback (event 1100). A session published without a qualified target breaks the SDK contract: the port releases it and reports RollbackUnconfirmed. Tests select another process through the fake, as Cheat Engine's window would, and prove that the lease made there survives the next observation while the earlier one is refused; a change observed during the allocation keys the lease to the process it was made in. The consumed SDK inventories record the three new members. --- .../Domains/Allocations/AllocationClient.cs | 44 ++++++++-- .../Domains/Allocations/IAllocationPort.cs | 8 +- .../Domains/Allocations/SdkAllocationPort.cs | 2 + .../Domains/ITargetSelectionBinder.cs | 38 +++++++++ .../Domains/ProcessClient.cs | 69 ++++++++++++---- .../Domains/ValueScanning/IValueScanPort.cs | 9 ++ .../Domains/ValueScanning/SdkValueScanPort.cs | 29 +++++-- .../Domains/ValueScanning/ValueScanner.cs | 41 ++++++++-- ...EngineClientServiceCollectionExtensions.cs | 6 +- .../Allocations/AllocationClientTests.cs | 82 +++++++++++++++++-- .../ValueScanning/ValueScannerTests.cs | 40 ++++++++- .../Infrastructure/TryContractTests.cs | 40 +++++---- .../TestSupport/FakeAllocationPort.cs | 9 ++ .../TestSupport/FakeSelectedTarget.cs | 61 ++++++++++++++ .../TestSupport/FakeValueScanPort.cs | 9 ++ .../SdkContract/ConsumedSdkSurface.cs | 3 + .../SdkContract/SdkApiUsage.cs | 3 + 17 files changed, 427 insertions(+), 66 deletions(-) create mode 100644 libs/CheatEngine.Client.Core/Domains/ITargetSelectionBinder.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/TestSupport/FakeSelectedTarget.cs diff --git a/libs/CheatEngine.Client.Core/Domains/Allocations/AllocationClient.cs b/libs/CheatEngine.Client.Core/Domains/Allocations/AllocationClient.cs index 046564b..dddf5bd 100644 --- a/libs/CheatEngine.Client.Core/Domains/Allocations/AllocationClient.cs +++ b/libs/CheatEngine.Client.Core/Domains/Allocations/AllocationClient.cs @@ -11,9 +11,17 @@ namespace CheatEngine.Client.Core.Domains.Allocations; /// Allocates target memory through CheatEngine.SDK's allocator, on Cheat Engine's main thread. /// -/// A published allocation is registered with the activation and with the target selection it was made in, in the -/// same main-thread callback that made it, so no path leaves it without an owner: a registration that fails, and a -/// cancellation observed after the allocation, release it at once. +/// +/// A published allocation is registered with the activation and with the target selection it was made in, in the +/// same main-thread callback that made it, so no path leaves it without an owner: a registration that fails, and +/// a cancellation observed after the allocation, release it at once. +/// +/// +/// The target selection is the one of the process incarnation that CheatEngine.SDK bound the allocation to +/// (), not the last selection the Client observed: a process selected in Cheat +/// Engine's own window since then advances the epoch before the lease is registered, so the next observation never +/// releases an allocation whose own process is still selected. +/// /// internal sealed class AllocationClient : IAllocationClient { @@ -22,13 +30,17 @@ internal sealed class AllocationClient : IAllocationClient private readonly SdkMainThreadDispatcher _dispatcher; private readonly IAllocationPort _port; + private readonly ITargetSelectionBinder _selection; /// Creates the allocation client of an activation. /// The activation dispatcher. + /// The owner of the observed target selection, the activation's process client. /// The allocator; CheatEngine.SDK's when omitted. - internal AllocationClient(SdkMainThreadDispatcher dispatcher, IAllocationPort? port = null) + internal AllocationClient(SdkMainThreadDispatcher dispatcher, ITargetSelectionBinder selection, + IAllocationPort? port = null) { _dispatcher = dispatcher ?? throw new ArgumentNullException(nameof(dispatcher)); + _selection = selection ?? throw new ArgumentNullException(nameof(selection)); _port = port ??

TryAllocate thus threw a lifecycle exception for a target change while the activation was running, and an allocation whose release was refused stayed in the target with no address reported, contrary to IAllocationClient. TargetSelectionLifetime could also let an ObjectDisposedException escape. Both callbacks now check ThrowIfInactive before Cheat Engine creates anything, so an ended or stopping activation, a deactivation cleanup scope included, throws before any resource exists. A registration refused afterwards releases the owner and goes through the new LeaseRegistration.Refused: an activation that ended or is stopping still throws its lifecycle exception, whose message now states what the release left, and a running activation gets a TargetChanged failure, Completed when the release was confirmed and CleanupUnconfirmed otherwise, with the allocation's size and address in the message. An unexpected exception is still rethrown after the release. Tests cover the refusal inside a cleanup scope, an activation stopping during the call, and a registration refused by a moved selection. --- .../Domains/Allocations/AllocationClient.cs | 36 ++++++--- .../Domains/Allocations/AllocationMapping.cs | 2 +- .../Domains/ValueScanning/ValueScanner.cs | 33 ++++++--- .../Infrastructure/LeaseRegistration.cs | 49 +++++++++++++ .../Allocations/AllocationClientTests.cs | 73 ++++++++++++++++++- .../ValueScanning/ValueScannerTests.cs | 27 +++++++ 6 files changed, 194 insertions(+), 26 deletions(-) create mode 100644 libs/CheatEngine.Client.Core/Infrastructure/LeaseRegistration.cs diff --git a/libs/CheatEngine.Client.Core/Domains/Allocations/AllocationClient.cs b/libs/CheatEngine.Client.Core/Domains/Allocations/AllocationClient.cs index dddf5bd..1ea37e3 100644 --- a/libs/CheatEngine.Client.Core/Domains/Allocations/AllocationClient.cs +++ b/libs/CheatEngine.Client.Core/Domains/Allocations/AllocationClient.cs @@ -14,7 +14,9 @@ namespace CheatEngine.Client.Core.Domains.Allocations; /// /// A published allocation is registered with the activation and with the target selection it was made in, in the /// same main-thread callback that made it, so no path leaves it without an owner: a registration that fails, and -/// a cancellation observed after the allocation, release it at once. +/// a cancellation observed after the allocation, release it at once.

The round-trip text is exponent notation for 0.00001 ("1E-05") and has no decimals for 100, so an exact scan matched a whole unit around the value, or almost every small float. Both factories now take the number of decimals, 0 to 15, and write the value rounded to it in fixed-point notation with a "." separator, never in exponent notation: FromDouble(100, 2) is "100.00".

The four types and the builder opt-in carry [Experimental("CECLIENT5004")], whose UrlFormat points at the new anchor of the Abstractions README; their PublicAPI lines take the [CECLIENT5004] prefix. ClientCapabilityId.AutoAssemblerPatches is stable. CheatEngineClientBuilder.EnableAutoAssemblerPatches() mirrors the unsafe Lua opt-in: it registers the client and a registration marker that CoreClientPolicy.EnableAutoAssemblerPatches reads, keeps a single registration when called twice and refuses a foreign one. Configuration cannot enable it. Without it nothing is registered, the catalog row's policy gate is Missing, and the client refuses every call with CapabilityUnavailable and NotStarted before any dispatch (Q44). The only Cheat Engine calls go through SdkAutoAssemblerPort: AutoAssemblerPatcher.TryApplyWithOutcome and TryCheck(script, true) behind LuaAdmission, with bounded options (host text copied up to 4096 UTF-8 bytes, the unprojected disable-info snapshot at the SDK minimum). AutoAssemblerMapping maps every SDK category totally. Applied returns the lease; AppliedTargetChanged returns it with AppliedAfterTargetChange and a new warning event 1800; GlobalUnavailable is CapabilityUnavailable and TargetIdentityUnavailable keeps its kind, both NotStarted; ProtectedLuaFailure is LuaError, InvalidResult InvalidHostResult; HandoffFailed is BindingError with CleanupUnconfirmed. Rejected is OperationRejected with the SDK's own effect, Unknown, not the NotApplied the plan named: CheatEngine.SDK 2.0.0 documents that a rejected script can have applied part of its effects, and NotApplied would claim that nothing changed. The lease is a target-bound HostResourceLease registered inside the dispatched callback; a refused registration releases the patch at once. It releases through ReleaseWithTargetOutcome, one attempt that never rebuilds [DISABLE]; a consumed owner reports its status again without a second call, and RequiresManualRecovery covers every unconfirmed disable. DisableInfo is not projected. The harness reports the new capability in its Q44 loop, the AOT probe composes the opt-in, and the SDK surface inventories gain the consumed AutoAssemblerPatcher members. TryContractTests adds the family, and sonar excludes the new port from coverage. The catalog row carries ExperimentalDiagnosticId CECLIENT5004, so its implementation gate reason names the id; the capability documentation accepts either operational label followed by the experimental id, and the experimental diagnostics catalogue lists CECLIENT5004. --- .github/workflows/sonar.yml | 2 +- README.md | 8 +- .../Assembly/AutoAssemblerCheckResult.cs | 59 ++ .../Assembly/AutoAssemblerScript.cs | 5 +- .../Assembly/IAssemblyClient.cs | 21 +- .../Assembly/IAutoAssemblerClient.cs | 95 +++ .../Assembly/IAutoAssemblerPatchLease.cs | 84 +- .../PublicAPI.Unshipped.txt | 54 +- .../CheatEngine.Client.Abstractions/README.md | 40 + .../Runtime/ClientCapabilityId.cs | 9 +- .../Domains/Assembly/AutoAssemblerClient.cs | 267 ++++++ .../Domains/Assembly/AutoAssemblerMapping.cs | 177 ++++ .../Assembly/AutoAssemblerPatchLease.cs | 91 ++ .../Domains/Assembly/IAutoAssemblerPort.cs | 110 +++ .../Domains/Assembly/SdkAutoAssemblerPort.cs | 98 +++ .../Assembly/UnavailableAssemblyClient.cs | 20 +- .../Domains/ClientCapabilityCatalog.cs | 14 +- .../Domains/RuntimeClient.cs | 10 +- .../Infrastructure/CoreClientPolicy.cs | 13 +- .../Infrastructure/ICoreDiagnostics.cs | 22 + libs/CheatEngine.Client.Core/README.md | 13 +- .../AutoAssemblerPatchesRegistration.cs | 10 + .../CheatEngineClientBuilder.cs | 41 + ...EngineClientServiceCollectionExtensions.cs | 5 +- .../ClientCoreDiagnosticsLog.cs | 10 +- .../LoggerCoreDiagnostics.cs | 21 +- .../PublicAPI.Unshipped.txt | 1 + .../README.md | 8 +- libs/CheatEngine.Client.Hosting/README.md | 2 +- .../Assembly/AssemblyContractsTests.cs | 2 + .../Assembly/AutoAssemblerContractsTests.cs | 54 ++ tests/CheatEngine.Client.AotProbe/Program.cs | 9 +- .../Domains/AutoAssemblerClientTests.cs | 781 ++++++++++++++++++ .../Domains/AutoAssemblerMappingTests.cs | 130 +++ .../Domains/ClientCapabilityCatalogTests.cs | 27 +- .../Domains/RuntimeClientTests.cs | 35 +- .../UnavailableAdvancedClientsTests.cs | 6 - .../Infrastructure/CoreDiagnosticsTests.cs | 5 + .../Infrastructure/HostResourceLeaseTests.cs | 4 + .../Infrastructure/TryContractTests.cs | 67 +- .../AutoAssemblerPatchesRegistrationTests.cs | 99 +++ .../LoggerCoreDiagnosticsTests.cs | 11 +- .../README.md | 2 +- .../QualificationScenarios.cs | 2 +- .../CapabilityDocumentationTests.cs | 16 +- .../ClientExperimentalDiagnosticsTests.cs | 5 +- .../SdkContract/ConsumedSdkSurface.cs | 31 + .../SdkContract/SdkApiUsage.cs | 33 + 48 files changed, 2528 insertions(+), 101 deletions(-) create mode 100644 libs/CheatEngine.Client.Abstractions/Assembly/AutoAssemblerCheckResult.cs create mode 100644 libs/CheatEngine.Client.Abstractions/Assembly/IAutoAssemblerClient.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/Assembly/AutoAssemblerClient.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/Assembly/AutoAssemblerMapping.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/Assembly/AutoAssemblerPatchLease.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/Assembly/IAutoAssemblerPort.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/Assembly/SdkAutoAssemblerPort.cs create mode 100644 libs/CheatEngine.Client.Extensions.DependencyInjection/AutoAssemblerPatchesRegistration.cs create mode 100644 tests/CheatEngine.Client.Abstractions.Tests/Assembly/AutoAssemblerContractsTests.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Domains/AutoAssemblerClientTests.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Domains/AutoAssemblerMappingTests.cs create mode 100644 tests/CheatEngine.Client.Extensions.DependencyInjection.Tests/AutoAssemblerPatchesRegistrationTests.cs diff --git a/.github/workflows/sonar.yml b/.github/workflows/sonar.yml index 44b1094..62c69b1 100644 --- a/.github/workflows/sonar.yml +++ b/.github/workflows/sonar.yml @@ -183,7 +183,7 @@ jobs: # (xUnit has no attached Cheat Engine process or Lua state): its lines are untestable, not merely # untested, and its non-SDK branches keep the tests they allow next to it (for example # SdkTableRecordMutationPortTests).

Subject: [PATCH 213/321] Add experimental instruction assembly and disassembly IAssemblyClient becomes operational over CheatEngine.SDK 2.0.0's instruction APIs: Try/Assemble, Try/Disassemble, Try/GetInstructionLength (renamed from GetInstructionSize) and Try/GetPreviousInstruction. AssemblyInstructionRequest gains an InstructionEncodingPreference (option enum None=0, Short, Long, Far) and SkipRangeCheck, both passed to Cheat Engine's assemble unchanged. AssemblyInstructionSnapshot carries Address, Length, AddressText, Opcode, Extra, Text (Opcode, then Extra when not blank) and Bytes. The four types and ICheatEngineClient.Assembly carry [Experimental("CECLIENT5003")], whose UrlFormat points at the new anchor of the Abstractions README; their PublicAPI lines take the [CECLIENT5003] prefix. The capability id Client.Assembly is stable. AssemblyClient runs each call in one dispatched callback. The port asks CheatEngine.SDK for one Lua admission (LuaAdmission) and the instruction profile is observed once (InstructionProfiles.TryObserveCurrent); an address above 4 GiB on a 32-bit profile is refused with OperationRejected and NotStarted before any instruction function of Cheat Engine is called, and every SDK call of the Client call receives that same profile. Assembly uses a 16-byte buffer bounded by MemoryResourceLimits.MaximumReadBytes, retries once with the RequiredLength the SDK reports, and refuses an empty result as InvalidHostResult, since the SDK reports an empty byte table as a success. Disassembly gets the length, reads that many bytes with the counted TargetMemory.TryReadBytes, then disassembles: the read sits between two SDK target checks, the bytes never come from the disassembler's text, and the text is bounded by MaximumStringBytes. InstructionMapping maps every InstructionOperationStatus: InvalidProfile and InvalidResult to InvalidHostResult, AddressExceedsProfileWidth and InstructionRejected to OperationRejected, TargetNotSelected to TargetNotAttached, TargetChanged to TargetChanged, DestinationTooSmall after the retry and OutputTooLong to ResultLimitExceeded, GlobalUnavailable to CapabilityUnavailable, LuaFailure to LuaError, UnsupportedTargetBackend to Unsupported, and Unknown or an unknown value to Unknown. A status of the profile observation is NotStarted. A step that follows an earlier instruction call of the same Client call (the assembly retry, the byte read and the disassembly of Disassemble) is never NotStarted: a refusal before its own call is Completed, because Cheat Engine work already ran. A rejected instruction is NotApplied, since assemble never writes the target; an estimate of the previous instruction wider than the profile is OperationRejected with Completed. Byte-read failures keep MemoryAccessFailureMapping and SDK faults go through SdkBoundary. UnavailableAssemblyClient is deleted and DI composes AssemblyClient with the validated MemoryResourceLimits. Allocations are already operational, so no domain is contract-only any more: the unused UnavailableCapabilityFailure helper is deleted, and the contract-only ratchet becomes EveryCapabilityHasAnOperationalAdapter, which requires one operational Core adapter per capability and no Unavailable* placeholder. The catalog row becomes Operational with ExperimentalDiagnosticId CECLIENT5003, the capability tables say "Operational adapter, experimental (CECLIENT5003)", and the Try/cancellation table gains the instruction family and loses its capability-gated row. The DI, catalog and runtime tests list no contract-only capability any more, TryContractTests drops its UnavailableCapability cases, UnavailableAdvancedClientsTests is deleted, and CoreDiagnosticsTests drops the two refusals the unavailable adapter emitted. InstructionEncodingPreference joins the option enums, the SDK surface inventories gain the consumed instruction members, TryContractTests adds the family, the experimental diagnostics catalogue lists CECLIENT5003, the AOT probe keeps the four types reachable, the harness and the test doubles acknowledge CECLIENT5003, and sonar excludes SdkInstructionPort from coverage. --- .github/workflows/sonar.yml | 2 +- README.md | 9 +- .../Assembly/AssemblyInstructionRequest.cs | 41 +- .../Assembly/AssemblyInstructionSnapshot.cs | 69 +- .../Assembly/IAssemblyClient.cs | 100 ++- .../Assembly/InstructionEncodingPreference.cs | 31 + .../ICheatEngineClient.cs | 7 +- .../PublicAPI.Unshipped.txt | 78 +- .../CheatEngine.Client.Abstractions/README.md | 43 +- .../Runtime/ClientCapabilityId.cs | 4 + .../CheatEngineClient.cs | 2 + .../CheatEngineClientDomainServices.cs | 2 + .../Domains/Assembly/AssemblyClient.cs | 374 +++++++++ .../Domains/Assembly/IInstructionPort.cs | 116 +++ .../Domains/Assembly/InstructionMapping.cs | 218 +++++ .../Domains/Assembly/SdkInstructionPort.cs | 94 +++ .../Assembly/UnavailableAssemblyClient.cs | 88 -- .../Domains/ClientCapabilityCatalog.cs | 8 +- .../Events/UnavailableCapabilityFailure.cs | 45 - libs/CheatEngine.Client.Core/README.md | 22 +- ...EngineClientServiceCollectionExtensions.cs | 17 +- .../Assembly/AssemblyContractsTests.cs | 126 ++- .../Assembly/AutoAssemblerContractsTests.cs | 1 + tests/CheatEngine.Client.AotProbe/Program.cs | 6 +- .../Composition/CheatEngineClientTests.cs | 2 + .../Domains/AssemblyClientTests.cs | 778 ++++++++++++++++++ .../Domains/ClientCapabilityCatalogTests.cs | 12 +- .../Domains/InstructionMappingTests.cs | 159 ++++ .../Domains/RuntimeClientTests.cs | 68 +- .../UnavailableAdvancedClientsTests.cs | 71 -- .../Infrastructure/CoreDiagnosticsTests.cs | 18 +- .../Infrastructure/TryContractTests.cs | 105 ++- ...eClientServiceCollectionExtensionsTests.cs | 23 +- .../Scanning/AobFluentBuilderTests.cs | 2 + .../CheatEngineClientPluginTests.cs | 2 + .../ClientActivationLifecycleTests.cs | 2 + .../QualificationScenarios.cs | 2 + .../Architecture/CapabilityRatchetTests.cs | 77 +- .../ClientExperimentalDiagnosticsTests.cs | 3 + .../OutcomeEnumConventionTests.cs | 2 + .../SdkContract/ConsumedSdkSurface.cs | 24 + .../SdkContract/SdkApiUsage.cs | 19 + 42 files changed, 2459 insertions(+), 413 deletions(-) create mode 100644 libs/CheatEngine.Client.Abstractions/Assembly/InstructionEncodingPreference.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/Assembly/AssemblyClient.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/Assembly/IInstructionPort.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/Assembly/InstructionMapping.cs create mode 100644 libs/CheatEngine.Client.Core/Domains/Assembly/SdkInstructionPort.cs delete mode 100644 libs/CheatEngine.Client.Core/Domains/Assembly/UnavailableAssemblyClient.cs delete mode 100644 libs/CheatEngine.Client.Core/Domains/Events/UnavailableCapabilityFailure.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Domains/AssemblyClientTests.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Domains/InstructionMappingTests.cs delete mode 100644 tests/CheatEngine.Client.Core.Tests/Domains/UnavailableAdvancedClientsTests.cs diff --git a/.github/workflows/sonar.yml b/.github/workflows/sonar.yml index 62c69b1..21839c3 100644 --- a/.github/workflows/sonar.yml +++ b/.github/workflows/sonar.yml @@ -183,7 +183,7 @@ jobs: # (xUnit has no attached Cheat Engine process or Lua state): its lines are untestable, not merely # untested, and its non-SDK branches keep the tests they allow next to it (for example # SdkTableRecordMutationPortTests).

214/321] End an Auto Assembler lease whose disable could not begin CheatEngine.SDK 2.0.0's AutoAssemblerPatch consumes and unroots its disable information before any Lua work, and TryDisable disposes the reference on its NotInvoked paths too: a detached Lua runtime, a disable reference that is no longer current, a closed Lua admission or an autoAssemble function that cannot be resolved. The SDK then sets its own RequiresManualRecovery, as TargetReleaseOutcome does for every status except Unspecified and Released. The lease mapped that status with the shared SdkReleaseOutcomes.FromTarget, whose NotInvoked is the retryable CleanupUnavailable. The lease therefore never ended: every Release reported CleanupUnavailable again without a Cheat Engine call, LeaseReleaseOutcome.IsRetryable contradicted the lease's own RequiresManualRecovery, and the deactivation report classified a patch that may still be injected as CapabilityUnavailable. AutoAssemblerMapping.ToReleaseOutcome now maps NotInvoked for this owner to RefusedRuntimeChanged with NotStarted, the Client kind for a release refused before any Cheat Engine call that leaves the resource to manual recovery, and delegates every other status to FromTarget, which stays unchanged for the other target-bound owners. The lease ends on its first attempt, a later Release reports AlreadyReleased, and the deactivation report carries RuntimeChanged. A CleanupUnavailable outcome now only means that the release could not be dispatched, which leaves the disable information for a later release. The lease and IAutoAssemblerPatchLease remarks, the CECLIENT5004 section of the Abstractions README and the Core README say so. The mapping gains a totality test over TargetReleaseStatus and a test that no status of a consumed owner is retryable. The lease test that locked in the retryable report now expects the terminal outcome, and a new test shows that an undispatched release keeps the patch releasable. --- .../Assembly/IAutoAssemblerPatchLease.cs | 16 +++--- .../CheatEngine.Client.Abstractions/README.md | 8 +-- .../Domains/Assembly/AutoAssemblerMapping.cs | 24 +++++++++ .../Assembly/AutoAssemblerPatchLease.cs | 15 +++--- libs/CheatEngine.Client.Core/README.md | 5 +- .../Domains/AutoAssemblerClientTests.cs | 52 ++++++++++++++++--- .../Domains/AutoAssemblerMappingTests.cs | 47 +++++++++++++++++ 7 files changed, 144 insertions(+), 23 deletions(-) diff --git a/libs/CheatEngine.Client.Abstractions/Assembly/IAutoAssemblerPatchLease.cs b/libs/CheatEngine.Client.Abstractions/Assembly/IAutoAssemblerPatchLease.cs index 630c89b..e934992 100644 --- a/libs/CheatEngine.Client.Abstractions/Assembly/IAutoAssemblerPatchLease.cs +++ b/libs/CheatEngine.Client.Abstractions/Assembly/IAutoAssemblerPatchLease.cs @@ -14,11 +14,12 @@ namespace CheatEngine.Client.Assembly; /// The lease holds the only disable information Cheat Engine returned for the patch.

For a feature that injects code, "releases" reads as "disables", which never happens on that path. ProcessClient advances the target-selection epoch only after it observed the new selection, so TargetSelectionLifetime.Advance disposes the lease while Cheat Engine already targets the new process. CheatEngine.SDK 2.0.0's AutoAssemblerPatcher.TryDisable then validates the captured incarnation and returns Refused(TargetChanged) after TakeOwnership consumed the disable information, and its finally block unroots the table. The lease ends with RefusedTargetChanged and RequiresManualRecovery, the patch stays in the previous process, and attaching to that process again cannot disable it. The remarks of IAutoAssemblerClient and IAutoAssemblerPatchLease, a new "Target change" bullet in the CECLIENT5004 section and the family's Try/cancellation row now tell callers to release every patch lease before selecting another process, and say what happens otherwise. The behaviour is unchanged; the lease test that encodes it is renamed SelectingAnotherTargetEndsTheLeaseWithoutDisablingThePatch. --- .../Assembly/IAutoAssemblerClient.cs | 12 +++++++++--- .../Assembly/IAutoAssemblerPatchLease.cs | 6 ++++++ libs/CheatEngine.Client.Abstractions/README.md | 10 +++++++--- .../Domains/AutoAssemblerClientTests.cs | 4 +++- 4 files changed, 25 insertions(+), 7 deletions(-) diff --git a/libs/CheatEngine.Client.Abstractions/Assembly/IAutoAssemblerClient.cs b/libs/CheatEngine.Client.Abstractions/Assembly/IAutoAssemblerClient.cs index 7ad2a26..3aa2a4c 100644 --- a/libs/CheatEngine.Client.Abstractions/Assembly/IAutoAssemblerClient.cs +++ b/libs/CheatEngine.Client.Abstractions/Assembly/IAutoAssemblerClient.cs @@ -21,9 +21,15 @@ namespace CheatEngine.Client.Assembly; /// applies the script once through Cheat Engine's autoAssemble and returns /// the only owner of the disable information Cheat Engine returned.

After a process was selected in Cheat Engine's own window, a patch that CheatEngine.SDK applied in, and bound to, the new process was keyed to the old epoch, so the next Processes.GetCurrent or Refresh ended its lease while its own target was still selected: CheatEngine.SDK then accepted the release and ran [DISABLE] on a patch the application still owned. CheatEngine.SDK 2.0.0's AutoAssemblerPatch exposes the incarnation it qualified before the activation and validates on release (TargetIncarnation). AutoAssemblerClient now takes the activation's ITargetSelectionBinder, the ProcessClient singleton in DI, as the allocation and value-scan clients do. In the dispatched callback it records that incarnation as an observation of the selection (BindOwner) and registers the lease under the epoch this leaves; a change advances the epoch first and ends the earlier selection's leases, and the advance is logged after the callback (event 1100). An AppliedTargetChanged patch keeps the incarnation observed before the activation, as before. The callback also checks ThrowIfInactive before Cheat Engine applies anything. A registration refused afterwards releases the patch and goes through LeaseRegistration.Refused instead of the former TargetChanged, InvalidState or ActivationExpired failure: an activation that ended or is stopping throws its lifecycle exception, whose message states what the release left, and a running activation gets TargetChanged, Completed when the release was confirmed and CleanupUnconfirmed otherwise. An unexpected exception is rethrown after the release. Tests mirror the allocation ones: a patch applied in a process selected in Cheat Engine's window survives the next observation while the earlier lease ends refused, a change observed during the activation keys the lease to the process it was applied in, a patch in the observed process keeps the observed epoch, and the refusals in a cleanup scope, during a stop and by a moved selection report what the release left. TryContractTests passes the binder. The CECLIENT5004 section, the IAutoAssemblerClient remarks, the SelectionEpoch documentation and the Core README say so, and the consumed SDK inventories record AutoAssemblerPatch.TargetIncarnation. --- .../Assembly/IAutoAssemblerClient.cs | 11 +- .../Assembly/IAutoAssemblerPatchLease.cs | 2 +- .../CheatEngine.Client.Abstractions/README.md | 13 +- .../Domains/Assembly/AutoAssemblerClient.cs | 99 ++++++----- .../Assembly/AutoAssemblerPatchLease.cs | 5 +- .../Domains/Assembly/IAutoAssemblerPort.cs | 9 + .../Domains/Assembly/SdkAutoAssemblerPort.cs | 2 + libs/CheatEngine.Client.Core/README.md | 6 +- .../CheatEngineClientBuilder.cs | 3 +- .../Domains/AutoAssemblerClientTests.cs | 165 +++++++++++++++++- .../Infrastructure/TryContractTests.cs | 16 +- .../SdkContract/ConsumedSdkSurface.cs | 1 + .../SdkContract/SdkApiUsage.cs | 1 + 13 files changed, 262 insertions(+), 71 deletions(-) diff --git a/libs/CheatEngine.Client.Abstractions/Assembly/IAutoAssemblerClient.cs b/libs/CheatEngine.Client.Abstractions/Assembly/IAutoAssemblerClient.cs index 3aa2a4c..996c177 100644 --- a/libs/CheatEngine.Client.Abstractions/Assembly/IAutoAssemblerClient.cs +++ b/libs/CheatEngine.Client.Abstractions/Assembly/IAutoAssemblerClient.cs @@ -25,11 +25,12 @@ namespace CheatEngine.Client.Assembly; /// /// /// Release every patch lease before selecting another process.

No test reached the second check. The cleanup-scope test copied from the allocation client is refused at admission: AllocationClient admits with ThrowIfDispatchAllowed, which lets a deactivation cleanup scope through, but the Auto Assembler admission uses ThrowIfInactive, which makes no exception for it. That test now says so and asserts that nothing was dispatched, applied or released. A new theory stops or ends the activation after the dispatch was admitted and before the callback runs, through a hook of the test invoker. The callback's check then refuses the activation with the lifecycle or the activation-expired exception, before any apply or release; both cases fail when that check is removed. The body of 1bcec9b says that the refusal in a cleanup scope reports what the release left. It does not: nothing is applied or released there, and the admission throws its plain lifecycle exception. --- .../Domains/AutoAssemblerClientTests.cs | 44 +++++++++++++++++++ 1 file changed, 44 insertions(+) diff --git a/tests/CheatEngine.Client.Core.Tests/Domains/AutoAssemblerClientTests.cs b/tests/CheatEngine.Client.Core.Tests/Domains/AutoAssemblerClientTests.cs index 6796ce6..bfafac4 100644 --- a/tests/CheatEngine.Client.Core.Tests/Domains/AutoAssemblerClientTests.cs +++ b/tests/CheatEngine.Client.Core.Tests/Domains/AutoAssemblerClientTests.cs @@ -336,7 +336,43 @@ public void AnActivationDuringTheDeactivationCleanupIsRefusedBeforeCheatEngineAp client.TryApplyPatch(new AutoAssemblerScript(Script), out _, out _, Token)); } + // Unlike an allocation, an activation is admitted with ThrowIfInactive, which makes no exception for a cleanup + // scope: the admission refuses it before anything is dispatched, and nothing is applied or released. + Assert.Equal(0, _invoker.Calls); + Assert.Equal(0, _port.ApplyCalls); + Assert.Equal(0, _port.Owner!.ReleaseCalls); + } + + [Theory] + [Trait("Qualification", "Q43")] + [InlineData(false, typeof(CheatEngineClientLifecycleException))] + [InlineData(true, typeof(CheatEngineActivationExpiredException))] + public void AnActivationThatStopsOrEndsAfterItsAdmissionIsRefusedBeforeCheatEngineApplies(bool ends, + Type expected) + { + AutoAssemblerClient client = CreateClient(); + // The admission and the dispatch let the activation through; it stops or ends before the callback runs on + // Cheat Engine's main thread, so only the callback's own check can refuse it. + _invoker.BeforeCallback = () => + { + if (ends) + { + _context.IsCurrent = false; + } + else + { + _context.Stop(); + } + }; + + CheatEngineClientException refused = Assert.ThrowsAny(() => + client.TryApplyPatch(new AutoAssemblerScript(Script), out _, out _, Token)); + + Assert.IsType(expected, refused); + Assert.Equal(AutoAssemblerClient.ApplyOperation, refused.Failure.Operation); + Assert.Equal(1, _invoker.Calls); Assert.Equal(0, _port.ApplyCalls); + Assert.Equal(0, _port.Owner!.ReleaseCalls); } [Theory] @@ -650,6 +686,13 @@ internal bool Refuse set; } + /// Gets or sets work that runs once the dispatch was admitted, before the callback. + internal Action?

That release frees nothing. The Client ends the earlier selection's leases only once it observes the change, when Cheat Engine already targets the new process, so CheatEngine.SDK refuses the release of an allocation, a value-scan session or an Auto Assembler patch before any Cheat Engine call (RefusedTargetChanged, or another refusal such as RefusedTargetIdentityUnavailable for a session) and consumes the owner. The allocation or the patch stays in the previous process, the MemScan and FoundList of a session stay in Cheat Engine, and the lease ends with an outcome that requires manual recovery, which the deactivation drain reports. The allocation, value-scan and Auto Assembler client tests assert this outcome. The generic docs now say so and tell the application to release a target-bound lease before selecting another process, as the Auto Assembler docs already did. The same sentence is corrected in the CECLIENT5001 and CECLIENT5002 sections of the Abstractions README, the IValueScanner and ITargetMemoryLease remarks, and the internal TargetMemoryLease and ValueScanSession remarks.

For the Auto Assembler that one disable was mapped by SdkReleaseOutcomes.FromTarget instead of the lease's own mapping, and an unconfirmed disable escaped as an OwnershipHandoffException that reached SdkBoundary.Classify as Unknown/Unknown.

InvalidState is reserved for Client-side state, and an unconfirmed host cleanup is an indeterminate host result. - AobScanMapping.ClassifyCreationFailure reports those statuses as IndeterminateHostResult with CleanupUnconfirmed; the fallback statuses are unchanged. - A scan that succeeded but whose result-list or session release was not confirmed is IndeterminateHostResult with CleanupUnconfirmed too (it was InvalidState), so the throwing form raises CheatEngineOperationException. A release that follows another failure keeps that failure's kind, as before. - The "differ on purpose" paragraph leaves the ValueScanMapping remarks, and the AobScanMapping remarks, the bounded-route README paragraph and the Patterns row of the Try and cancellation table state the shared rule. - PatternScannerBoundedRouteTests, PatternScannerBehaviorTests and the host-outcome totality test follow.

From ff5b7ef8f84a25707b6a8ab94a7f54d2da8260c7 Mon Sep 17 00:00:00 2001 From: AriusII Date: Fri, 25 Sep 2026 05:22:50 +0200 Subject: [PATCH 232/321] Enforce the public API naming and vocabulary charter The 1.0.0 surface freezes for 1.x, so its names, forms and vocabulary are fixed now and written down as a charter in the Abstractions README, with tests for its mechanical rules. Exceptions and failures: - CheatEngineClientLifecycleException is renamed CheatEngineInvalidStateException: InvalidState is also a pointer width, a table load or a session state. - CheatEngineClientException is abstract with a private protected constructor, and every other Client exception constructor is internal. CheatEngineFailure.ToException(token) creates, without throwing, the exception Throw raises, so every exception keeps the complete failure and its HostEffect. Core creates them through an internal ClientExceptions helper: NotStarted for admission refusals; LeaseRegistration.Refused passes Completed or CleanupUnconfirmed. - The CheatEngineFailure constructor rejects an undefined kind. - The root remarks say that no Try form throws an SDK exception, how XDetailed forms behave, and "activation epoch" everywhere. - ILuaModule.Register says how a module refuses: it throws the exception of CheatEngineFailure.Throw or ToException, and the Client reports the failure any Client exception carries. Leases: ICheatEngineLease.RequiresManualRecovery replaces the copies on ITargetMemoryLease and IAutoAssemblerPatchLease. It becomes true when a release attempt leaves the resource behind. CheatEngine.SDK 2.0.0 sets an Auto Assembler patch's own flag only inside a release, so the lease reads it only for a status this version does not recognize, and CanDisable is the early signal that a release cannot run [DISABLE]. IValueScanSession gains SelectionEpoch; ILuaModuleLease.Epoch goes; IAutoAssemblerPatchLease.IsEnabled is CanDisable. Runtime: IsCheatEngine64Bit is PointerSize CheatEngineBitness, SystemArchitecture is HostArchitecture (host facts first in the constructor), ClientCapabilityEvidence.IsExecutable goes. Processes: LocalProcessSnapshot, LocalProcessEnumerationRequest and LocalProcessEnumerationResult; MaximumItems is MaximumResults, since it truncates. Memory: the codec contexts' ConfiguredPointerSizeDiffersFromBitness is bool?; IMemoryCodec.TryRead/TryWrite and the contexts' TryReadBytes/ TryWriteBytes gain out CheatEngineFailure (a codec's non-default failure is published unchanged, the default one keeps today's classification); AttemptedCount is RequestedCount; the read outcome's ReadPrefix is Values, with the constructor (requestedCount, values, failedIndex, failure), which names the argument that contradicts the request; the string requests have public constructors instead of Create and CreateBounded; MaximumOperations is MaximumOperationCount; MemoryBatchWriteEffectState.Complete is Completed; MemoryBytesReadOutcome.IsComplete and MemoryResourceLimits.CreateSnapshot go (Core copies through the internal MemoryResourceLimitsCopy, which DI's validator also uses). Scanning and assembly: ScanAlignmentMode and ScanAlignment.Mode; PatternScanHostOutcomeKind with RuntimeChanged; the three skipped and unread PatternScanMetrics counts end in Count; ValueScanPage.TotalCount is ResultCount; ICheatEngineClient.Scans is ValueScans (operations ValueScans.*); GetPreviousInstruction is GetPreviousInstructionAddress. Value types: the nine record structs holding an ImmutableArray are plain readonly structs; TableLoadRequest, TableSaveRequest and MemoryRecordHierarchySnapshot have camelCase constructors, no init accessor and no Deconstruct. The charter names LeaseReleaseOutcome as the release outcome (LuaModuleReleaseOutcome is the module report mapped into it) and says that a record struct compares each member with its own equality (CheatEngineFailure's Exception by reference). Tests: PublicApiCharterTests (metadata scan: no SDK *Outcome, *Status or *Kind type in a public signature; Try/throwing twins and parameter order; no *Outcome enum; no settable public struct; no record struct with an ImmutableArray; no public exception constructor; the final sixteen ApprovedSdkClientTypes); PublicSurfaceInventoryTests (forbidden namespaces, Core exports nothing); OutcomeEnumConventionTests is total (OutcomeEnumsWithoutSuffix, ValueScanComparison and ValueScanValueType listed as option enums, PendingCharterEnums empty); lease, codec and exception tests follow. The Auto Assembler lease tests model the SDK flag as set only by a release, and a value-scan session's SelectionEpoch is the epoch GetCurrent observes. Compile fixes: DI DefaultMemoryCodecs and validator, Hosting's two refusals (ToException), the Lua generator's registrar (ToException, so a refused admission now throws the exception of its kind), Fluent, the harness, Benchmarks and the test doubles. ConsumedSdkSurface gains PointerSize::get_Bit64 for Core, already consumed by Abstractions and DI. Frozen-file exceptions: CoreFailureFactory.cs (the GetKind arm follows the rename, Lifecycle becomes InvalidState) and SdkBoundary.cs (ThrowIfActivationEnded throws through CheatEngineFailure.Throw, since the public constructor is gone; a doc-only remark says that LuaClient reports the failure of any Client exception a module throws); neither changes a classification. --- README.md | 18 +- .../Allocations/ITargetMemoryLease.cs | 21 +- .../Assembly/AssemblyInstructionSnapshot.cs | 2 +- .../Assembly/IAssemblyClient.cs | 4 +- .../Assembly/IAutoAssemblerClient.cs | 2 +- .../Assembly/IAutoAssemblerPatchLease.cs | 35 +- .../Dispatching/ICheatEngineDispatcher.cs | 12 +- .../ICheatEngineClient.cs | 14 +- .../ICheatEngineLease.cs | 18 + .../Lua/ILuaExecutionContext.cs | 2 +- .../Lua/ILuaModule.cs | 19 +- .../Lua/ILuaModuleLease.cs | 6 -

These operations allocate nothing in the target process. - **Partial-effect state**: a batch write runs in order and is never rolled back. `MemoryPrimitiveBatchWriteOutcome.EffectState` reports `NotStarted`, `Partial` (with `CompletedCount` and - `FailedIndex`), `Complete`, or `Unknown`. + `FailedIndex`), `Completed`, or `Unknown`. `MemoryStringReadRequest.MaximumLength` is passed unchanged as Cheat Engine's `readString` `maxlength` argument. Cheat Engine 7.7 does not document whether it counts bytes or characters, so treat it as a host-side bound. This is still to be qualified on a live host (C3). For admission, the Client charges it as bytes for UTF-8 and as twice that for UTF-16. +## Public API charter + +This charter is normative for every public type of the seven Client packages; the 1.x line only adds to it. +`PublicApiCharterTests`, `OutcomeEnumConventionTests`, `PublicClientSignatureBoundaryTests`, +`PublicSurfaceInventoryTests`, `DefaultOutputValueTests` and `OperationNameTests` check its mechanical rules. + +### Operation forms + +- **`TryX` and `X`.** An operation that can fail for an expected reason has a `TryX` form that returns `bool` with its + value in an `out` parameter and a classified `out CheatEngineFailure failure`, and a throwing `X` form with the same + inputs that returns the same value (or `void`) or throws that failure through `CheatEngineFailure.Throw(token)`. +- **`XDetailed`.** Some operations also return an outcome instead of throwing an expected failure + (`IPatternScanner.ScanDetailed`, `IMemoryClient.ReadBytesDetailed`, `ReadPrimitiveBatchDetailed`, + `WritePrimitiveBatchDetailed`); a Detailed form throws exactly what its `Try` form throws. +- **Parameter order.** Required inputs, then the inputs that are optional in the throwing form (required in the `Try` + form), then the `out` value, then `out CheatEngineFailure failure`, then `CancellationToken cancellationToken = + default`, always last. `ICheatEngineDispatcher` uses explicit overloads instead of an optional token. +- **Outputs.** A failed `Try` leaves its value output `default`. A lease or session output is nullable and annotated + `[NotNullWhen(true)]`. +- **Exemptions.** BCL-shaped pure lookups and parses (`ClientCapabilities.TryGet`, `AobPattern.TryParse`) have no + failure output and no throwing twin. Implementable callbacks (`ILuaOperation.TryExecute`, + `IMemoryCodec.TryRead`, `TryWrite`) and the codec contexts' `TryReadBytes` and `TryWriteBytes` keep the `Try` + shape, `out` failure included, without a token or a twin. + +### Registrations and leases + +- `RegisterX`/`TryRegisterX` installs a named resource that other code can also see, replace or remove (a symbol, a Lua + module) and returns the lease that owns it; its release never removes a resource the lease no longer owns + (`Replaced`, `Superseded`, `ExternallyRemoved`). A resource only its lease can reach is created by an action verb + (`Allocate`, `CreateSession`, `ApplyPatch`). A lease interface is named after the resource it owns. +- Every lease is an `ICheatEngineLease`: `Release()` returns a `LeaseReleaseOutcome`, `Dispose()` never throws, + `IsReleased` says that no later attempt will be made, `LastReleaseOutcome` keeps the last recorded attempt, and + `RequiresManualRecovery` says that what the lease owns may remain and this lease can no longer remove it. A release + of an ended lease returns `LastReleaseOutcome` without calling Cheat Engine. `AlreadyReleased` means only that the + owner reported nothing left to release. +- A target-bound lease (`ITargetMemoryLease`, `IValueScanSession`, `IAutoAssemblerPatchLease`) exposes `SelectionEpoch`. + No lease duplicates a fact of `ICheatEngineLease` or of its outcome. + +### Failures and exceptions + +- `CheatEngineFailure.Kind` says why and `HostEffect` how far the Cheat Engine primitive got. `InvalidState` is + reserved for Client-side state: the activation, a session or resource, or a target fact the operation requires. A + host rollback or release that was not confirmed is `IndeterminateHostResult` (or the kind of the failure that caused + it) with `CleanupUnconfirmed`. +- The exception type depends only on the kind: `Cancelled` → `CheatEngineOperationCanceledException`; + `ActivationExpired` → `CheatEngineActivationExpiredException`; `InvalidState` → + `CheatEngineInvalidStateException`; any other kind → `CheatEngineOperationException`. No Client exception has a + public constructor: `CheatEngineFailure.Throw(token)` throws one and `CheatEngineFailure.ToException(token)` creates + one, so every exception keeps the complete failure, including `HostEffect` (`NotStarted` for an admission refusal). +- `CheatEngineFailure.Operation` is `.`. `Service` is the `ICheatEngineClient` property that exposes + the service, `UnsafeLua` or `AutoAssembler` for the services only dependency injection registers, or `Client` for + the activation itself. `Member` is the public method the caller invoked, without `Try` or `Detailed`. A lease + release is `.Release`, and a failure raised inside a codec or a Lua operation context names the call that + runs it. `Operation` is safe to log; like `Message`, its text is not a compatibility contract. +- No `Try` form throws a CheatEngine.SDK exception. `CheatEngineFailure.Exception` may hold one: its type is not part + of this contract and changes with the SDK, so never type-test it. +- "Cancelled" is the Client's spelling for the failure kind and the host outcome; exception type names follow the BCL. + +### Value types and outcomes + +| Suffix | Meaning | Construction | +|---|---|---| +| `*Request`, `*Definition`, `*Update`, `*Search` | A validated input | One public constructor; named factories only for per-kind invariants (`ScanAlignment.AlignedTo`, `ValueScanFirstRequest.Exact`) | +| `*Snapshot` | An immutable copy of host state | Never settable | +| `*Info` | A group of facts inside `CheatEngineRuntimeSnapshot` | — | +| `*Result` | The value a successful call returns | — | +| `*Outcome` | What a Detailed form or a release reports; never an enum | — | +| `*Metrics` | Counts and durations, safe to log | — | + +- A **Detailed outcome** exposes `IsSuccess` (`Failure` is `null`), `Failure`, the payload under the name of its `Try` + form's `out` value (`Result`, `Bytes`, `Values`) and its facts. The **release outcome** of a lease, + `LeaseReleaseOutcome`, exposes `Kind`, `HostEffect` and exactly one of `IsComplete`, `IsRetryable` and + `RequiresManualRecovery`; `IsComplete` belongs to release outcomes only. `LuaModuleReleaseOutcome` is the report an + `ILuaModule.Unregister` implementation returns: it carries `Kind`, `IsComplete` and the module's counts, and the + Client maps it into the `LeaseReleaseOutcome` of the module's lease. +- Public value types are `readonly struct`s with get-only properties and an explicit constructor whose parameters are + camelCase; there are no `init` accessors and no positional records. A `record struct` is used only when member-wise + equality is meaningful. Each member compares with its own equality, so `CheatEngineFailure` compares its `Exception` + by reference; a type that holds an `ImmutableArray`, which also compares by reference, is a plain `readonly struct`. +- Every value a public member returns or a `Try` form publishes is safe to read at `default`: reference members are + empty (never `null`) and `ImmutableArray` members are empty. BCL outputs (`ImmutableArray`, `string?`) keep the + BCL's default. +- Counts end in `Count` (`RecordCount`, `ResultCount`, `RequestedCount`, `CompletedCount`) and byte lengths in `Length` + (`RequestedLength`, `ConfirmedLength`). Bounds are `Maximum`: `MaximumItems` fails with `ResultLimitExceeded`, + `MaximumResults` truncates and sets `IsTruncated`, `MaximumCount` bounds a page that reports `HasMore`, + `MaximumBytes` and `MaximumCount` are budgets, and `MaximumLength` is a host string bound. A truncated host + text has a `Truncated` companion flag. + +### Width vocabulary + +- `PointerSize` is the only width type: `ProcessSnapshot.Bitness`, `CheatEngineRuntimePlatformInfo.TargetBitness` and + `CheatEngineBitness`, `IMemoryReadContext.Bitness` and `IMemoryWriteContext.Bitness`. It is `Unknown` when not + observed and is never inferred from the ISA or the configured size. +- `ConfiguredPointerSizeBytes` (`int?`, the raw `getPointerSize()`) and `ConfiguredPointerSize` (its `PointerSize` + projection) are reported together; `ConfiguredPointerSizeDiffersFromBitness` is `bool?` everywhere, `null` when + either value is unknown. +- The ISA is `CheatEngineArchitecture`. Platform facts name their subject: `Host*`, `CheatEngine*`, `Target*`. + +### Enums + +- Every public enum is backed by `int`, declares every value explicitly and defines zero. A value never changes + meaning and a minor release can add values: handle an unrecognized value like `Unknown`. +- An **outcome enum** reports what happened or was observed: `Unknown = 0`, and its name ends in `Kind`, `Status`, + `State`, `Effect` or `Scope` (`PatternScanRouteReason` and `ClientCapabilityEvidenceReasonCode` are the listed + exceptions). An **option enum** is the caller's choice: its zero is the default choice and its name never ends in an + outcome suffix (`Mode`, `Preference`, `Protection`, `Encoding`, `Requirement`, `Comparison`, `Type`). No enum is + named `*Outcome`. + +### Call-only and Implementable interfaces + +The documentation of every public interface says whether it is **Call-only** (the Client implements it and applications +call it; a 1.x minor release can add members, so implement it only in a test double) or **Implementable** +(applications implement it and the Client calls it; its members are frozen for 1.x): `ILuaModule`, +`ILuaOperation`, `ILuaResultMapper`, `IMemoryCodec` and `ICheatEngineClientModule`. + +### CheatEngine.SDK types in public signatures + +Only these descriptive CheatEngine.SDK values appear in public signatures: `Address`, `TargetProcessId`, `ModuleName`, +`ModuleInfo`, `ModuleSectionInfo`, `MemoryRegionInfo`, `SymbolExpression`, `SymbolInfo`, `MemoryRecordId`, +`PointerSize`, `CheatEngineArchitecture`, `TargetAbi`, `CheatEngineVersion`, `VariableType`, `TargetBackend` and +`CheatEngineOperatingSystem`. No SDK outcome, status or kind type and no SDK exception type appears in a public +signature. Because these types are part of the Client's signatures, moving to CheatEngine.SDK 3.0 is a Client 2.0. + +### Shared vocabulary + +| Concept | Client name | Not | +|---|---|---| +| Activation epoch | `Epoch` (`ICheatEngineClient`, `ICheatEngineRuntime`, `CheatEngineRuntimeSnapshot`, `ILuaExecutionContext`) | "SDK lifecycle epoch", an epoch on a lease | +| Target-selection epoch | `SelectionEpoch` (`ProcessSnapshot`, every target-bound lease) | — | +| Lua runtime replaced | `RuntimeChanged`, `RefusedRuntimeChanged` | `RuntimeInvalidated` | +| Another target selected | `TargetChanged`, `RefusedTargetChanged` | — | +| Target identity not established | `TargetIdentityUnavailable` | — | +| Effect ran to completion | `Completed` (`CheatEngineHostEffect`, `MemoryBatchWriteEffectState`) | `Complete` | +| Size of the request | `RequestedCount`, `RequestedLength` | `AttemptedCount` | +| Done so far | `CompletedCount`, `ConfirmedLength` | — | +| Rows the host reported | `ResultCount` (value scans), `HostResultCount` (AOB), `RecordCount` (tables) | `TotalCount` | +| Local operating-system catalog | `Local*` (`LocalProcessId`, `LocalProcessSnapshot`, `GetLocalProcesses`) | `ProcessInfo*` | +| Cheat Engine's target | `Process*` (`ProcessSnapshot`, `IProcessClient`) | — | +| AOB request data / scanner report | `Aob*` / `PatternScan*` | — | +| Value scans | `ValueScan*`, `ICheatEngineClient.ValueScans` | `Scans` | +| Cut result / cut host text / partial page | `IsTruncated` / `Truncated` / `HasMore` | — | +| Host text (user data) | `Host` (`HostMessages`, `HostWarnings`) | — | +| Why, as text / as a typed value | `Reason`, `EffectiveReason` / `EffectiveReasonCode`, `RouteReason` | — | +| AOB range / value-scan range | `Start`–`End` (End is the last allowed match start) / `StartAddress`–`StopAddress` (Stop is exclusive) | — | + ## Contribution and Validation Changes here are public API changes.

An unbound builder was a valid value that failed only at its terminal, and each route had to be documented, tested and frozen for 1.x. Each domain now has one entry point, an extension on the service that runs its terminals: - memory: IMemoryClient.At(Address) and IMemoryClient.Batch() (T : unmanaged); - AOB: IPatternScanner.Aob(string) and the new IPatternScanner.Aob(AobPattern) for an already parsed pattern, which rejects the empty default pattern. The static Memory class, MemoryAddressBuilder.Using, MemoryPointerChainBuilder.Using and the ICheatEngineClient.Aob extension are removed (call client.Patterns.Aob instead). A builder is bound when it is created and never rebound; only a default builder has no service, and its messages now name the bound entry point. The explicit-memory overloads and their RS0026/RS0027 pragmas were already gone, so PendingOverloadSuppressions stays empty. Consumers are migrated in the same commit: the Fluent tests (plus FluentSurfaceTests, which pins one bound entry point per domain and the absence of constructors, factories and Using), the facade smoke test, the allocation gate and the Fluent benchmark (bound to a DispatchProxy service that is never called), and the Fluent README.

Their compiler-generated Equals, GetHashCode, == and != compared the bound service as one more field, and with ToString they froze a value semantics nobody needs into the 1.x surface: 30 PublicAPI lines. MemoryAddressBuilder, AobScanBuilder, AobFirstMatchBuilder, AobManyMatchBuilder and AobSingleMatchBuilder become plain readonly structs, like MemoryPointerChainBuilder and MemoryPrimitiveBatchBuilder already were. A builder declares no Equals, GetHashCode, ToString, equality operator or constructor; it keeps only what System.ValueType gives every struct, including the implicit parameterless constructor that yields the default value. That default value has no service: every operation that runs or selects a terminal (including Follow, RequireSingle, FirstOrNone and Take) throws an InvalidOperationException that its XML documentation declares and whose message names the bound entry point. The AOB terminals now read IPatternScanner.ScanDetailed through one internal helper, AobTerminal, because its metrics say whether every row Cheat Engine returned was read (InBoundsCountIsExact). FirstOrNone returns null, RequireSingle reports NotFound and Take returns an empty result only for a factual zero: the bounded route's empty in-bounds result, a managed-filter global list whose rows all lie outside the request, or an empty list an unscoped global scan does return. A nil global result stays IndeterminateHostResult (a scanner failure), and an empty copy that left rows unread is reported as IndeterminateHostResult by the terminal. Core already fails the known cases (a nil list, a bounded destination filled with rows outside the request), so this is a guard rather than a change against Core. No terminal uses a first-found scan (CESDK5011). Failures the terminals create after a completed scan carry HostEffect.Completed instead of Unknown, and are named Patterns.Scan, after the scan they run, as the operation-name charter requires (they were Aob.FirstOrNone, Aob.Take and Aob.RequireSingle); OperationNameTests and the Abstractions README charter now cover Fluent. RequireSingle reports AmbiguousMatch only when Core copied two matches. One copied match is unique only when the copy is exhaustive and not truncated; otherwise the terminal reports IndeterminateHostResult. With a copy limit of two, a truncated copy of one match never proves a second match: Core's bounded route publishes that shape when its full destination held one match inside the request next to rows it dropped (matches that straddle the module end) and left a row unread. The global route reads every row of the same request and proves the match unique, so the bounded route must not call it ambiguous. Take(n) keeps the contract of AobScanRequest.MaximumResults: any positive n is forwarded unchanged, every route copies at most 65,535 addresses, and a result cut by that cap reports IsTruncated. Every terminal documents the Client exceptions it can raise. A throwing terminal (the AOB Execute methods, and the memory Read, Write, ReadBytes, WriteBytes, ReadString, WriteString, ReadWith, WriteWith, Resolve and batch Read and Write) raises what CheatEngineFailure.Throw maps the failure to: CheatEngineOperationException, CheatEngineOperationCanceledException, CheatEngineActivationExpiredException, or CheatEngineInvalidStateException for InvalidState. A Try terminal still throws the two lifecycle exceptions once the activation has ended or while it is stopping. The memory terminals also document the argument exceptions of the requests they build, and InModule and InRange those of the module name and the range. Naming charter on Fluent's own surface (TryX/X pairs): ReadUtf8, ReadUtf16, WriteUtf8 and WriteUtf16 had no Try form. They are removed rather than paired, as the Abstractions string requests keep only the by-encoding form; ReadString/TryReadString and WriteString/TryWriteString with a MemoryStringEncoding remain. Tests: FluentSurfaceTests proves that the seven builders are readonly, non-record structs that declare no equality members, that every default builder rejects its operations, that each of those operations documents the InvalidOperationException, and that every terminal documents its Client exceptions. The AOB tests check FirstOrNone's factual zero on every route, the unread-row cases, the truncated single match that stays indeterminate, the Completed host effect and Take's unchanged limit; the memory tests check that a cancelled token reaches the service and surfaces as an OperationCanceledException. FluentAobTerminalCompositionTests, in Core.Tests, compiles the Fluent AOB sources in (a project reference would change that project's lock file) and runs the three terminals against Core's real PatternScanner on the bounded, managed-filter and unscoped routes, including the straddling matches and a bounded destination full of dropped rows. The Fluent README documents the route-by-route answers. --- .../CheatEngine.Client.Abstractions/README.md | 2 +- .../Memory/MemoryAddressBuilder.cs | 327 +++++++++++++----- .../Memory/MemoryPointerChainBuilder.cs | 47 ++- .../Memory/MemoryPrimitiveBatchBuilder.cs | 92 ++++- .../PublicAPI.Unshipped.txt | 34 -- libs/CheatEngine.Client.Fluent/README.md | 48 ++- .../Scanning/AobFirstMatchBuilder.cs | 64 ++-- .../Scanning/AobManyMatchBuilder.cs | 56 +-- .../Scanning/AobScanBuilder.cs | 97 +++++- .../Scanning/AobSingleMatchBuilder.cs | 82 +++-- .../Scanning/AobTerminal.cs | 99 ++++++ .../CheatEngine.Client.Core.Tests.csproj | 7 + .../FluentAobTerminalCompositionTests.cs | 218 ++++++++++++ tests/CheatEngine.Client.Core.Tests/README.md | 5 + .../FluentSurfaceTests.cs | 150 +++++++- .../Memory/MemoryAddressBuilderTests.cs | 53 ++- .../CheatEngine.Client.Fluent.Tests/README.md | 15 +- .../Scanning/AobFluentBuilderTests.cs | 281 ++++++++++++--- .../Architecture/OperationNameTests.cs | 8 +- 19 files changed, 1404 insertions(+), 281 deletions(-) create mode 100644 libs/CheatEngine.Client.Fluent/Scanning/AobTerminal.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Composition/FluentAobTerminalCompositionTests.cs diff --git a/libs/CheatEngine.Client.Abstractions/README.md b/libs/CheatEngine.Client.Abstractions/README.md index 26e173b..a291586 100644 --- a/libs/CheatEngine.Client.Abstractions/README.md +++ b/libs/CheatEngine.Client.Abstractions/README.md @@ -727,7 +727,7 @@ qualified on a live host (C3).

Providers added there receive the Hosting lifecycle events and the Core diagnostic events, which log through the activation provider's logger factory. It also gains PluginDirectory, the folder of the concrete plugin assembly. Cheat Engine starts a managed plugin through its .NET host, so AppContext.BaseDirectory describes the hosting process, not the plugin's deployment folder. The getter is the only IL3000 suppression of the shipped code, justified by ADR-02 (the managed-hostfxr profile loads the plugin from its folder, never from a single-file bundle); an assembly without a file location is refused with an InvalidOperationException. SingleFileSuppressionTests keeps that count at one. Hosting cannot set a file-provider base path itself without a Microsoft.Extensions.FileProviders reference, so the configuration base is PluginDirectory by contract: the template, the Hosting README and the root README call SetBasePath(builder.PluginDirectory) instead of SetBasePath(AppContext.BaseDirectory). The builder constructor and BuildServiceProvider become internal: Hosting creates the builder for each enable and builds the provider after Configure returns, so no public path can create either. ApprovedFrameworkIntegrationTypes gains ILoggingBuilder and loses ServiceProvider, which no public signature exposes any more. --- README.md | 2 +- .../CheatEngineClientPlugin.cs | 2 +- .../CheatEnginePluginBuilder.cs | 73 ++++++++- .../PublicAPI.Unshipped.txt | 4 +- libs/CheatEngine.Client.Hosting/README.md | 9 +- .../content/CheatEngine.Plugin/Plugin.cs | 3 +- .../content/CheatEngine.Plugin/README.md | 6 +- .../CheatEngine.Client.Hosting.Tests.csproj | 5 + .../CheatEngineClientPluginTests.cs | 134 +++++++++++++++++ .../CheatEnginePluginBuilderTests.cs | 142 +++++++++++++++++- .../README.md | 7 + .../appsettings.json | 7 + .../SingleFileSuppressionTests.cs | 56 +++++++ .../PublicClientSignatureBoundaryTests.cs | 2 +- 14 files changed, 432 insertions(+), 20 deletions(-) create mode 100644 tests/CheatEngine.Client.Hosting.Tests/appsettings.json create mode 100644 tests/CheatEngine.Client.Repository.Tests/SourcePolicy/SingleFileSuppressionTests.cs diff --git a/README.md b/README.md index 0cb6f55..b490a51 100644 --- a/README.md +++ b/README.md @@ -128,7 +128,7 @@ public sealed class Plugin : CheatEngineClientPlugin protected override void Configure(CheatEnginePluginBuilder builder) { builder.Configuration - .SetBasePath(AppContext.BaseDirectory) + .SetBasePath(builder.PluginDirectory) .AddJsonFile("appsettings.json", optional: true, reloadOnChange: false); builder.Client.AddModule(); diff --git a/libs/CheatEngine.Client.Hosting/CheatEngineClientPlugin.cs b/libs/CheatEngine.Client.Hosting/CheatEngineClientPlugin.cs index 3698fdf..815c981 100644 --- a/libs/CheatEngine.Client.Hosting/CheatEngineClientPlugin.cs +++ b/libs/CheatEngine.Client.Hosting/CheatEngineClientPlugin.cs @@ -77,7 +77,7 @@ protected sealed override void OnEnable() CheatEngineHostEffect.NotStarted).ToException(); } - CheatEnginePluginBuilder builder = new(); + CheatEnginePluginBuilder builder = new(GetType().Assembly); ActivationConstruction construction = new(builder); Activation? activation = null; diff --git a/libs/CheatEngine.Client.Hosting/CheatEnginePluginBuilder.cs b/libs/CheatEngine.Client.Hosting/CheatEnginePluginBuilder.cs index 4dd775f..23d78e1 100644 --- a/libs/CheatEngine.Client.Hosting/CheatEnginePluginBuilder.cs +++ b/libs/CheatEngine.Client.Hosting/CheatEnginePluginBuilder.cs @@ -1,34 +1,48 @@ +using System.Diagnostics.CodeAnalysis; + using CheatEngine.Client.Extensions.DependencyInjection; using Microsoft.Extensions.Configuration; using Microsoft.Extensions.DependencyInjection; +using Microsoft.Extensions.Logging; + +using ReflectionAssembly = System.Reflection.Assembly; namespace CheatEngine.Client.Hosting; /// Builds the managed configuration and service provider for one Cheat Engine plugin activation. /// -/// A builder is intentionally single-use.

It references CheatEngine.SDK.Hosting only (HostLog.Write, HostLog.IsEnabled, HostLogLevel, verified against 2.0.0) and is added by nothing unless the plugin calls it on builder.Logging. LogLevel maps to the four host levels: Trace and Debug to Trace, Information, Warning, and Error and Critical to Error; None is never written. IsEnabled and every write go through HostLog.IsEnabled, so HostLog.MinimumLevel decides what reaches the sink. No level appears in the public options. By default an entry carries the category, the event id, the message template read from {OriginalFormat} and the exception type name, never an argument value or an exception message (Q46). CheatEngineHostLogOptions.IncludeFormattedMessages writes the formatted message and passes the exception instead. The provider registers once; a later call keeps the first options. Hosting now reads the runtime snapshot once at the start of cleanup, inside the main-thread cleanup scope where it may still dispatch, and logs event 8 (Warning, epoch only) when Lua.ExternalStateResetDetected reports that Cheat Engine replaced its Lua state outside the plugin's control (A8). The read is diagnostics only: a failed or throwing snapshot changes no cleanup outcome. The Hosting README documents the provider, event 8, and the SDK's own opt-in identification line (HostLog.IdentifyOnEnable and CHEATENGINE_SDK_IDENTIFY_ON_ENABLE=1). ConsumedSdkSurface and SdkApiUsage gain the HostLog members Hosting now consumes. The host log tests replace the process-wide sink in a serial collection. --- .../CheatEngine.Client.Hosting.csproj | 2 +- .../CheatEngineClientPlugin.cs | 29 +++ .../CheatEngineHostLogExtensions.cs | 67 +++++ .../CheatEngineHostLogOptions.cs | 31 +++ .../CheatEngineHostLogProvider.cs | 111 +++++++++ .../ClientHostingLog.cs | 9 + .../PublicAPI.Unshipped.txt | 7 + libs/CheatEngine.Client.Hosting/README.md | 33 +++ .../CheatEngineClientPluginTests.cs | 95 ++++++- .../CheatEngineHostLogProviderTests.cs | 232 ++++++++++++++++++ .../README.md | 9 +- .../SdkContract/ConsumedSdkSurface.cs | 4 + .../SdkContract/SdkApiUsage.cs | 3 + 13 files changed, 628 insertions(+), 4 deletions(-) create mode 100644 libs/CheatEngine.Client.Hosting/CheatEngineHostLogExtensions.cs create mode 100644 libs/CheatEngine.Client.Hosting/CheatEngineHostLogOptions.cs create mode 100644 libs/CheatEngine.Client.Hosting/CheatEngineHostLogProvider.cs create mode 100644 tests/CheatEngine.Client.Hosting.Tests/CheatEngineHostLogProviderTests.cs diff --git a/libs/CheatEngine.Client.Hosting/CheatEngine.Client.Hosting.csproj b/libs/CheatEngine.Client.Hosting/CheatEngine.Client.Hosting.csproj index ef268b5..eb0c741 100644 --- a/libs/CheatEngine.Client.Hosting/CheatEngine.Client.Hosting.csproj +++ b/libs/CheatEngine.Client.Hosting/CheatEngine.Client.Hosting.csproj @@ -4,7 +4,7 @@ true true $(TargetsForTfmSpecificContentInPackage);_CheatEngineClientHostingPackLuaGenerator - The CheatEngineClientPlugin base class and one-provider-per-activation host for in-process Cheat Engine plugins, with the Lua module source generator and the plugin project checks. + The CheatEngineClientPlugin base class and one-provider-per-activation host for in-process Cheat Engine plugins, with an opt-in Cheat Engine host log provider, the Lua module source generator and the plugin project checks. diff --git a/libs/CheatEngine.Client.Hosting/CheatEngineClientPlugin.cs b/libs/CheatEngine.Client.Hosting/CheatEngineClientPlugin.cs index 815c981..6f5c6e3 100644 --- a/libs/CheatEngine.Client.Hosting/CheatEngineClientPlugin.cs +++ b/libs/CheatEngine.Client.Hosting/CheatEngineClientPlugin.cs @@ -5,6 +5,7 @@ using CheatEngine.Client.Extensions.DependencyInjection; using CheatEngine.Client.Modules; using CheatEngine.Client.Results; +using CheatEngine.Client.Runtime; using CheatEngine.SDK.Hosting.Plugin; using Microsoft.Extensions.DependencyInjection; @@ -219,6 +220,7 @@ private List CleanupActivation(Activation activation) report.Attempt(CleanupStage.CleanupScope); using (activation.Cleanup.EnterCleanupScope()) { + LogExternalLuaStateReset(activation); report.Record(CleanupStage.ModuleCallbacks, activation.Lifecycle.Cleanup(OnClientDisabling)); report.Run(CleanupStage.ClientResources, activation.Cleanup.DrainOwnedResourcesForDisable); } @@ -255,6 +257,33 @@ private static void LogIdentification(Activation activation, Type pluginType) }); } + /// + /// Warns (event 8) when the runtime snapshot reports that CheatEngine.SDK detected an external Lua state reset during + /// this activation (A8). + /// + /// + /// The fact is sticky until the next enable.

Its README, the builder and the registration extensions now say so, and say that composing the Client in a provider Hosting does not own is not supported in 1.0: the Client services capture the SDK plugin context of one enable. In the root README package table, Hosting is the supported composition root and DI is used only through it. A5: AddMemoryCodec and DefaultMemoryCodecs are removed, with their tests. IMemoryClient never resolves a codec implicitly; the built-in primitives need none, and a codec for any other type is an application service (Services.AddSingleton, TCodec>()) passed with MemoryReadRequest or MemoryWriteRequest. The template reads its Int32 probe through the primitive route instead of an injected codec. The Abstractions and Core READMEs and the IMemoryReadContext and IMemoryWriteContext remarks no longer describe a built-in Address codec or built-in codecs: the Client ships none, so a codec chooses its own byte order. Core's internal ICorePointerCodecPolicy, which only the removed Address codec called in production, now has test callers only and is left to the Core charter cleanup. ValidateCheatEngineClientOptions and CheatEngineClientOptionsSemanticValidator become internal sealed: the registration adds them and Hosting runs them at every enable. CheatEngineClientOptions.AllowedTableRoots becomes a read-only, never-null IList and MemoryResourceLimits a read-only, never-null object; binding and Configure delegates fill them, and the null guards they made necessary are gone. The Coexistence fixtures, the template and the tests read the root count through Count. A10: CheatEngineClientPlugin documents the inherited protected static CheatEnginePlugin.Context as a raw SDK escape hatch outside the Client's guarantees, and the Handle-free paragraph of the ICheatEngineClient root remark says that its guarantee covers the Client surface only and points to that documentation. ApprovedFrameworkGenericCollectionTypes gains IList`1; ApprovedFrameworkIntegrationTypes loses ValidateOptionsResult, which no public signature exposes any more. ConsumedSdkSurface loses the PointerSize and Address references of the removed DI Address codec; Core still consumes those members, so SdkApiUsage is unchanged. --- README.md | 4 +- .../ICheatEngineClient.cs | 12 +- .../Memory/IMemoryReadContext.cs | 4 +- .../Memory/IMemoryWriteContext.cs | 4 +- .../CheatEngine.Client.Abstractions/README.md | 2 +- libs/CheatEngine.Client.Core/README.md | 4 +- ...ient.Extensions.DependencyInjection.csproj | 2 +- .../CheatEngineClientBuilder.cs | 30 +- .../CheatEngineClientOptions.cs | 25 +- ...eatEngineClientOptionsSemanticValidator.cs | 23 +- ...EngineClientServiceCollectionExtensions.cs | 26 +- .../DefaultMemoryCodecs.cs | 130 ------ .../PublicAPI.Unshipped.txt | 13 +- .../README.md | 51 ++- .../ValidateCheatEngineClientOptions.cs | 3 +- .../CheatEngineClientPlugin.cs | 25 +- libs/CheatEngine.Client.Hosting/README.md | 16 +- .../Modules/PluginClientModule.cs | 7 +- .../content/CheatEngine.Plugin/README.md | 4 +- ...gineClientOptionsSemanticValidatorTests.cs | 38 +- ...eClientServiceCollectionExtensionsTests.cs | 57 ++- .../CompositionSurfaceTests.cs | 68 +++ .../DefaultMemoryCodecsTests.cs | 404 ------------------ .../README.md | 17 +- .../CheatEngineClientPluginTests.cs | 4 +- .../CheatEnginePluginBuilderTests.cs | 2 +- .../PluginA/CoexistencePluginA.cs | 2 +- .../PluginB/CoexistencePluginB.cs | 2 +- .../CoexistencePluginCollision.cs | 2 +- .../PublicClientSignatureBoundaryTests.cs | 4 +- .../SdkContract/ConsumedSdkSurface.cs | 10 - 31 files changed, 262 insertions(+), 733 deletions(-) delete mode 100644 libs/CheatEngine.Client.Extensions.DependencyInjection/DefaultMemoryCodecs.cs create mode 100644 tests/CheatEngine.Client.Extensions.DependencyInjection.Tests/CompositionSurfaceTests.cs delete mode 100644 tests/CheatEngine.Client.Extensions.DependencyInjection.Tests/DefaultMemoryCodecsTests.cs diff --git a/README.md b/README.md index b490a51..44da74b 100644 --- a/README.md +++ b/README.md @@ -229,8 +229,8 @@ public contracts ───────────────────── | Package | Purpose | Consume directly when | |-------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------|--------------------------------------------------------| | [`CheatEngine.Client`](src/CheatEngine.Client/README.md) | Umbrella package for the high-level fluent and hosting experience | Building a normal plugin | -| [`CheatEngine.Client.Hosting`](libs/CheatEngine.Client.Hosting/README.md) | `CheatEngineClientPlugin` and one-provider-per-activation host | Integrating the host into an existing composition root | -| [`CheatEngine.Client.Extensions.DependencyInjection`](libs/CheatEngine.Client.Extensions.DependencyInjection/README.md) | Explicit DI registrations, modules, memory codecs, and options | Composing the Client without the plugin base | +| [`CheatEngine.Client.Hosting`](libs/CheatEngine.Client.Hosting/README.md) | `CheatEngineClientPlugin` and one-provider-per-activation host | Hosting a plugin (the supported composition root) | +| [`CheatEngine.Client.Extensions.DependencyInjection`](libs/CheatEngine.Client.Extensions.DependencyInjection/README.md) | Hosting's composition layer: DI registrations and options | Only through Hosting in 1.0 (standalone unsupported) | | [`CheatEngine.Client.Fluent`](libs/CheatEngine.Client.Fluent/README.md) | Immutable fluent memory and AOB builders | Depending only on fluent request construction | | [`CheatEngine.Client.Abstractions`](libs/CheatEngine.Client.Abstractions/README.md) | Contracts, requests, failures, and value vocabulary | Referencing contracts without an implementation | | [`CheatEngine.Client.Core`](libs/CheatEngine.Client.Core/README.md) | SDK-facing implementation | Normally composed through DI, not called directly | diff --git a/libs/CheatEngine.Client.Abstractions/ICheatEngineClient.cs b/libs/CheatEngine.Client.Abstractions/ICheatEngineClient.cs index 9698ed3..3216cb8 100644 --- a/libs/CheatEngine.Client.Abstractions/ICheatEngineClient.cs +++ b/libs/CheatEngine.Client.Abstractions/ICheatEngineClient.cs @@ -22,11 +22,13 @@ namespace CheatEngine.Client; /// /// /// Handle-free surface.

Hosting logged it only when a runtime snapshot succeeded and reported Lua.ExternalStateResetDetected, but the snapshot starts with RuntimeObservations.TryObserveRuntimeInfo, whose Lua admission the SDK refuses once it has detected an external reset: the acquisition that detects the reset refuses too, LuaRuntime.AcquireOperation throws, and the snapshot fails. The combination the test double produced was unreachable, and every disable paid for a snapshot, its host probes and a Core RuntimeSnapshotCaptured event to read one static flag. The internal cleanup bridge now exposes the SDK's sticky flag (SdkBoundary.ExternalStateResetDetected, a lock-free read that never dispatches). Hosting reads it once after the ModuleCallbacks and ClientResources stages, whose Lua admissions are the last ones of the activation and can be the ones that detect the reset, and before the scope and provider that own the logger are disposed. No snapshot is taken during cleanup any more. A reset first detected when the SDK detaches Lua, after the Client cleanup, is reported only by the SDK's own LuaStateReplacedExternally host log line; the Hosting README says so. The tests use a runtime double that refuses the snapshot the way the real stack does after a reset and prove that cleanup never asks it, that event 8 is logged once between the releases and the end of cleanup whether the reset was detected during the activation or by the releases, and that no reset, or a failing read, changes nothing. --- .../CheatEngineClientActivationCleanup.cs | 2 + .../ICheatEngineClientActivationCleanup.cs | 14 +++ .../CheatEngineClientPlugin.cs | 29 +++-- .../ClientHostingLog.cs | 4 +- libs/CheatEngine.Client.Hosting/README.md | 13 +- .../CheatEngineClientPluginTests.cs | 118 +++++++++++++----- .../README.md | 5 +- 7 files changed, 133 insertions(+), 52 deletions(-) diff --git a/libs/CheatEngine.Client.Extensions.DependencyInjection/CheatEngineClientActivationCleanup.cs b/libs/CheatEngine.Client.Extensions.DependencyInjection/CheatEngineClientActivationCleanup.cs index 26ff9ea..5d4ab2c 100644 --- a/libs/CheatEngine.Client.Extensions.DependencyInjection/CheatEngineClientActivationCleanup.cs +++ b/libs/CheatEngine.Client.Extensions.DependencyInjection/CheatEngineClientActivationCleanup.cs @@ -8,6 +8,8 @@ internal sealed class CheatEngineClientActivationCleanup(CoreLifetime lifetime) { private readonly CoreLifetime _lifetime = lifetime ?? throw new ArgumentNullException(nameof(lifetime)); + public bool ExternalLuaStateResetDetected => SdkBoundary.ExternalStateResetDetected; + public IDisposable EnterCleanupScope() { return _lifetime.EnterCleanupScope(); diff --git a/libs/CheatEngine.Client.Extensions.DependencyInjection/ICheatEngineClientActivationCleanup.cs b/libs/CheatEngine.Client.Extensions.DependencyInjection/ICheatEngineClientActivationCleanup.cs index 00bf812..053a1c1 100644 --- a/libs/CheatEngine.Client.Extensions.DependencyInjection/ICheatEngineClientActivationCleanup.cs +++ b/libs/CheatEngine.Client.Extensions.DependencyInjection/ICheatEngineClientActivationCleanup.cs @@ -7,6 +7,20 @@ namespace CheatEngine.Client.Extensions.DependencyInjection; /// internal interface ICheatEngineClientActivationCleanup { + /// + /// Gets whether CheatEngine.SDK detected that Cheat Engine replaced its Lua state outside the plugin's control + /// during this activation (A8). + /// + /// + /// The SDK's own fact, sticky until the next enable: a lock-free read on any thread that never dispatches and + /// never admits Lua work.

An unknown fact is written as null, never derived. Observation keys follow the Client's public names: host.architecture, host.cheatEngineBitnessBytes, the metric counts with their Count suffix, and the requested count of memory_batch_partial. aob() names the route (scope, host outcome, route reason, target identity verified) and every PatternScanMetrics field. A global zero is IndeterminateHostResult with the NoResult host outcome, a bounded zero is a factual NoMatches, and truncation is proven from the Client's own counts instead of a local copy of the documented copy cap. The Q28 module check applies the whole-match rule of PatternScanner and compares the bounded result with the global result as address sets. capabilities(0) becomes the Q44 observation: the evidence gates of every capability, and for the opt-in capabilities whether the activation registered IAutoAssemblerClient or IUnsafeLuaClient. Without the opt-in nothing is registered, so no call can reach Cheat Engine; the function makes no call of its own and is no longer mutating. The dead allocation, instruction and value-scan probes are gone. The scenario module hands the activation's service provider to the Lua functions and uses the Client's own Patterns and Memory. The README and the project comment describe the Client's live runner instead of a future one. The Coexistence owner probe now retains a real experimental allocation and reports how its lease ended after a target change (RefusedTargetChanged with manual recovery), which its README protocol now expects instead of a capability-unavailable blocker. --- .../CoexistenceDiagnostics.cs | 11 +- .../README.md | 21 +- .../QualificationObservationWriterTests.cs | 19 ++ ...ine.Client.LivePlugin.Qualification.csproj | 7 +- .../Harness/QualificationObservation.cs | 30 +++ .../QualificationPlugin.cs | 12 +- .../QualificationScenarios.cs | 212 +++++++++++------- .../QualificationSession.cs | 16 +- .../README.md | 59 ++--- 9 files changed, 244 insertions(+), 143 deletions(-) diff --git a/tests/CheatEngine.Client.LivePlugin.Coexistence/CoexistenceDiagnostics.cs b/tests/CheatEngine.Client.LivePlugin.Coexistence/CoexistenceDiagnostics.cs index 30b9813..774981c 100644 --- a/tests/CheatEngine.Client.LivePlugin.Coexistence/CoexistenceDiagnostics.cs +++ b/tests/CheatEngine.Client.LivePlugin.Coexistence/CoexistenceDiagnostics.cs @@ -80,9 +80,10 @@ internal static string ObserveTarget() } /// - /// Retains one intentionally tiny allocation only when the exact Client/SDK tuple exposes a qualified allocation - /// owner.

Each new Lua function runs behind RunMutating, the gate and the write guard, and keeps the leases it creates in QualificationSession so a later step reports what the Client made of them. - value_scan (Q25, Q26): an int32 marker in the scratch region, first and next scans over that region, reset, state and release. The decimals action checks Cheat Engine's rounded comparison of the FromSingle and FromDouble texts: 3.14159 is found by 5, 3, 2 and 0 decimals and not by 3.2 or 3.15. - allocation (Q30.a, Q30.b): named leases, the region seen through the inspection API, and every release outcome. - instructions (Q32): the bytes Cheat Engine assembles for a fixed list and both jump encodings at the scratch window, and a round trip that writes mov eax,1; ret, disassembles, measures and restores it, for the bitness of the selected target. - aa_patch (Q35): a benign alloc plus registersymbol whose [DISABLE] frees both, and a failing variant. Configure composes EnableAutoAssemblerPatches() only for an authorized run that sets CECLIENT_QUALIFICATION_ENABLE_AA=1; without it the function is refused and capabilities(0) observes the Q44 policy refusal. - worker_admission (Q19): a worker marshals a Client call and calls a generated probe module's Register directly, which the SDK must refuse off the main thread. start returns at once and result reports "pending" until the worker ends, so the main thread never blocks. - table_save and table_load (Q34) below CECLIENT_QUALIFICATION_TABLE_ROOT, the activation's one allowed table root, and a save outside it. - integer_echo and address_echo for the 2^53 marshalling rule (CRIT-07). Two narrower RunMutating scopes exist, still behind the gate: OwnedResource releases a harness lease after a target change, which is what S3 observes, and FileAsProcessTarget checks that nothing is created on a file opened as a process. QualificationWriteGuard.EvaluateScope decides both and is tested. A lifecycle receipt sink (CECLIENT_QUALIFICATION_LIFECYCLE_FILE) receives every ledger entry and captured log template, so the runner reads what the disable at closeCE did (Q43); the log sink now captures Debug events. The inputs are honored only when the gate allowed the run. Configure also composes the Hosting host log provider for Q46 (AddCheatEngineHostLog, message templates only), so the Cheat Engine debug output the runner reads carries the Client's own events. --- .../CapturingLoggerProviderTests.cs | 2 + .../QualificationInputsTests.cs | 77 ++ .../QualificationLifecycleSinkTests.cs | 77 ++ ...ualificationPluginSourceComplianceTests.cs | 5 +- .../QualificationWriteGuardTests.cs | 29 + .../README.md | 13 +- .../Harness/CapturingLoggerProvider.cs | 6 +- .../Harness/QualificationInputs.cs | 48 ++ .../Harness/QualificationLedger.cs | 7 +- .../Harness/QualificationLifecycleSink.cs | 99 +++ .../Harness/QualificationWriteGuard.cs | 52 +- .../QualificationLuaFunctions.cs | 71 +- .../QualificationPlugin.cs | 38 +- .../QualificationScenarios.Experimental.cs | 716 ++++++++++++++++++ .../QualificationScenarios.Host.cs | 243 ++++++ .../QualificationScenarios.cs | 28 +- .../QualificationSession.cs | 95 ++- .../QualificationWorkerProbe.cs | 26 + .../README.md | 58 +- 19 files changed, 1648 insertions(+), 42 deletions(-) create mode 100644 tests/CheatEngine.Client.LivePlugin.Qualification.Tests/QualificationInputsTests.cs create mode 100644 tests/CheatEngine.Client.LivePlugin.Qualification.Tests/QualificationLifecycleSinkTests.cs create mode 100644 tests/CheatEngine.Client.LivePlugin.Qualification/Harness/QualificationInputs.cs create mode 100644 tests/CheatEngine.Client.LivePlugin.Qualification/Harness/QualificationLifecycleSink.cs create mode 100644 tests/CheatEngine.Client.LivePlugin.Qualification/QualificationScenarios.Experimental.cs create mode 100644 tests/CheatEngine.Client.LivePlugin.Qualification/QualificationScenarios.Host.cs create mode 100644 tests/CheatEngine.Client.LivePlugin.Qualification/QualificationWorkerProbe.cs diff --git a/tests/CheatEngine.Client.LivePlugin.Qualification.Tests/CapturingLoggerProviderTests.cs b/tests/CheatEngine.Client.LivePlugin.Qualification.Tests/CapturingLoggerProviderTests.cs index 46d8cb1..7275a52 100644 --- a/tests/CheatEngine.Client.LivePlugin.Qualification.Tests/CapturingLoggerProviderTests.cs +++ b/tests/CheatEngine.Client.LivePlugin.Qualification.Tests/CapturingLoggerProviderTests.cs @@ -8,6 +8,8 @@ namespace CheatEngine.Client.LivePlugin.Qualification.Tests;

ScenarioCatalog lists every Client scenario (id, level, sessions, whether it is waivable), the release gate (Q09, Q10, Q40, Q43, Q44, Q45, Q46, plus Q48 in CI through SdkConsumerContractTests) and the scenarios each capability requires. It is plain data, linked into the Core tests, where ClientCapabilityCatalogTests now prove that every scenario a capability row requires exists in the catalog and that the runner's capability map equals ClientCapabilityCatalog. SessionPlans describes S1 to S6 as reviewed data: targets, bundles, harness inputs (Auto Assembler opt-in, table root, lifecycle sink, fault stage) and the driver steps, composed from LuaDriverSteps. The driver gains a step model (once, poll, operator); the S0 driver renders the same text as before. A plugin toggle through Settings > Plugins is an operator step recorded notexecuted, so every check that needs one, and the checks that read the identification line or what closeCE disables, stay NotExecuted until the S0 spike records those facts. ScenarioEvaluators holds one C# evaluator per check over the harness observations, the driver's own steps, the debug output, the lifecycle sink and the facts the runner establishes (Q40 bundle identity, Q45 modules, Q46 debug output). A missing step is NotExecuted, never a pass. Q30.b is always NotExecuted: a reused process id cannot be produced on demand (waivable, A12). S3 expects the corrected target-change semantics: the leases made on A end with a refused release when Cheat Engine selects B, stay ended back on A, and only a new allocation releases as Released. The runner builds the coexistence fixtures, the plain CheatEngine.SDK 1.x neighbour (generated in a temporary consumer, answering with booleans only, compared by hand once with the SDK's published quick start) and the template instantiated as QualTemplatePlugin, and runs each session in one shared run directory, ledger and summary. The live facts of LiveSessionTests carry their Session and Qualification traits and stay excluded from CI. ScenarioCatalogTests, SessionPlanTests, EvaluatorTests and NeighbourPluginSourceTests cover all of it in CI without starting anything; NeighbourPluginSourceTests never reads the SDK repository. --- .../CheatEngine.Client.Core.Tests.csproj | 7 + .../Domains/ClientCapabilityCatalogTests.cs | 26 + .../README.md | 15 +- .../CheatEngine.Client.Tests.csproj | 2 + .../LiveQualification/EvaluatorTests.cs | 234 ++++++++ .../LiveQualificationFixture.cs | 11 + .../LiveSandboxSession.Sessions.cs | 432 ++++++++++++++ .../LiveQualification/LiveSandboxSession.cs | 2 +- .../LiveQualification/LiveSessionTests.cs | 162 +++++ .../LiveQualification/LuaDriverScript.cs | 302 +++++++--- .../NeighbourPluginSource.cs | 150 +++++ .../NeighbourPluginSourceTests.cs | 80 +++ .../LiveQualification/PluginBundleBuilder.cs | 233 +++++++- .../LiveQualification/ScenarioCatalog.cs | 105 ++++ .../LiveQualification/ScenarioCatalogTests.cs | 134 +++++ .../LiveQualification/ScenarioEvaluators.cs | 556 ++++++++++++++++++ .../LiveQualification/SessionEvidence.cs | 314 ++++++++++ .../LiveQualification/SessionPlanTests.cs | 208 +++++++ .../LiveQualification/SessionPlans.cs | 511 ++++++++++++++++ tests/CheatEngine.Client.Tests/README.md | 54 +- 20 files changed, 3430 insertions(+), 108 deletions(-) create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/EvaluatorTests.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/LiveSandboxSession.Sessions.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/LiveSessionTests.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/NeighbourPluginSource.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/NeighbourPluginSourceTests.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/ScenarioCatalog.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/ScenarioCatalogTests.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/ScenarioEvaluators.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/SessionEvidence.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/SessionPlanTests.cs create mode 100644 tests/CheatEngine.Client.Tests/LiveQualification/SessionPlans.cs diff --git a/tests/CheatEngine.Client.Core.Tests/CheatEngine.Client.Core.Tests.csproj b/tests/CheatEngine.Client.Core.Tests/CheatEngine.Client.Core.Tests.csproj index 8e9e0bd..cc6c51f 100644 --- a/tests/CheatEngine.Client.Core.Tests/CheatEngine.Client.Core.Tests.csproj +++ b/tests/CheatEngine.Client.Core.Tests/CheatEngine.Client.Core.Tests.csproj @@ -16,4 +16,11 @@ + + + + + diff --git a/tests/CheatEngine.Client.Core.Tests/Domains/ClientCapabilityCatalogTests.cs b/tests/CheatEngine.Client.Core.Tests/Domains/ClientCapabilityCatalogTests.cs index a8555d6..b9d8b46 100644 --- a/tests/CheatEngine.Client.Core.Tests/Domains/ClientCapabilityCatalogTests.cs +++ b/tests/CheatEngine.Client.Core.Tests/Domains/ClientCapabilityCatalogTests.cs @@ -3,6 +3,7 @@ using CheatEngine.Client.Core.Domains; using CheatEngine.Client.Runtime; +using CheatEngine.Client.Tests.LiveQualification; namespace CheatEngine.Client.Core.Tests.Domains; @@ -64,6 +65,31 @@ public void ScenarioIdentifiersAreWellFormedAndDistinctWithinARow() } } + [Fact] + public void EveryRequiredScenarioExistsInTheLiveScenarioCatalog() + { + string[] missing = + [ + ..

HostQualificationEvidence (Core/Qualification) is that place. It is data only, empty until the evidence commit of a recorded run fills it, and excluded from the qualified source digest, so recording a run does not change the digest of the sources the run qualified. HostQualificationGate derives each capability's gate from it. The gate is Satisfied only when evidence is embedded, the loaded CheatEngine.SDK.Engine is exactly the reviewed package (ConsumedSdkIdentity.ExactReviewedIdentity) and the evidence names that same informational version, the evidence records Cheat Engine 7.7.0.10621 and the supported host profile, the observed host is Cheat Engine 7.7.0.10621 64-bit on Windows, the target is a local process of an architecture the run qualified for the capability, this Client version without build metadata equals the recorded one, and every scenario the catalog row requires passed with no waiver. Otherwise it is Unknown and names the first condition that does not hold; without evidence the reason stays QualificationUnknownReason. Every value the Satisfied reason quotes has been compared. Client.UnsafeLuaExecution requires no scenario and is never qualified. RuntimeClient passes the observed host and target facts, with the loaded SDK informational version, and gains two test seams, the evidence and the Client version. The comparison of the host file version consumes CheatEngineVersion::op_Inequality, recorded in ConsumedSdkSurface.cs and SdkApiUsage.cs. HostQualificationGateTests cover every refusal, including evidence recorded for another SDK identity, Cheat Engine version or host profile, and the one Satisfied tuple; RuntimeClientTests cover the composed snapshot, and QualifiedSourceDigestTests prove that the evidence file exists and is no digest input while the gate is. --- .../Domains/ClientCapabilityCatalog.cs | 16 +- .../Domains/RuntimeClient.cs | 40 +++- .../HostQualificationEvidence.cs | 22 ++ .../Qualification/HostQualificationGate.cs | 209 ++++++++++++++++++ libs/CheatEngine.Client.Core/README.md | 9 +- .../Domains/RuntimeClientTests.cs | 32 ++- .../HostQualificationGateTests.cs | 207 +++++++++++++++++ .../QualifiedSourceDigestTests.cs | 12 + .../SdkContract/ConsumedSdkSurface.cs | 1 + .../SdkContract/SdkApiUsage.cs | 1 + 10 files changed, 531 insertions(+), 18 deletions(-) create mode 100644 libs/CheatEngine.Client.Core/Qualification/HostQualificationEvidence.cs create mode 100644 libs/CheatEngine.Client.Core/Qualification/HostQualificationGate.cs create mode 100644 tests/CheatEngine.Client.Core.Tests/Qualification/HostQualificationGateTests.cs diff --git a/libs/CheatEngine.Client.Core/Domains/ClientCapabilityCatalog.cs b/libs/CheatEngine.Client.Core/Domains/ClientCapabilityCatalog.cs index 123d787..28e84cc 100644 --- a/libs/CheatEngine.Client.Core/Domains/ClientCapabilityCatalog.cs +++ b/libs/CheatEngine.Client.Core/Domains/ClientCapabilityCatalog.cs @@ -37,8 +37,9 @@ internal enum CapabilityHostSource /// Where the policy gate comes from. /// Where the host gate comes from. /// -/// The live qualification scenarios whose receipts the qualification gate requires; empty when the capability can -/// never be qualified, so its qualification gate stays unknown. +/// The live qualification scenarios that must pass, none waived, before the qualification gate is satisfied +/// (HostQualificationGate); empty when the capability can never be qualified, so its qualification gate stays +/// unknown. /// internal sealed record ClientCapabilityDescriptor( ClientCapabilityId Id, @@ -63,15 +64,16 @@ internal string?

That assumes ordinary rounding to the text's decimals, while ValueScanValue's remarks quote Cheat Engine's own Lua documentation of rtRounded: "3" matches 3.0 to 3.4999 and "3.0" matches 3.00 to 3.0499, a range that reaches only half a unit above the text and so stops at 3.1425, below 3.14159's rounding. Under that rule both 3-decimal cases would report the probe as not found and Q25, which CECLIENT5001 needs, would fail on the documentation's own terms; under ordinary rounding the remarks mislead. Nothing established which rule the host applies. The two 3-decimal cases are now the discriminating cases: the harness records them with discriminating=true and no expectation. The other ten cases (5, 2 and 0 decimals must find the probe, 3.2 and 3.15 must not) hold under both rules and keep their expectations. The decimal-tolerance check passes when every expectation is met and the float and double cases of 3.142 agree, and its receipt names the rule: ordinary rounding when 3.142 finds the probe, the documented range when it does not. It fails when the two types disagree, since no single remark could then describe FromSingle and FromDouble. ValueScanValue's remarks keep the quotation and now say that it leaves open whether a value just below the text matches, and that Q25 records the rule; the change that records the run must state that rule there. SessionEvidence gains TryObserve for evaluators that read several fields of one observation. EvaluatorTests cover both rules, a disagreement, an unmet expectation and a missing case. --- .../Scanning/ValueScanValue.cs | 6 ++- .../QualificationScenarios.Experimental.cs | 22 ++++++--- .../README.md | 7 +-- .../LiveQualification/EvaluatorTests.cs | 46 +++++++++++------ .../LiveQualification/ScenarioEvaluators.cs | 49 ++++++++++++++++--- .../LiveQualification/SessionEvidence.cs | 18 +++++++ 6 files changed, 113 insertions(+), 35 deletions(-) diff --git a/libs/CheatEngine.Client.Abstractions/Scanning/ValueScanValue.cs b/libs/CheatEngine.Client.Abstractions/Scanning/ValueScanValue.cs index 27b4d8a..e5cd3c0 100644 --- a/libs/CheatEngine.Client.Abstractions/Scanning/ValueScanValue.cs +++ b/libs/CheatEngine.Client.Abstractions/Scanning/ValueScanValue.cs @@ -18,8 +18,10 @@ namespace CheatEngine.Client.Scanning; /// fixed-point notation, never in exponent notation, rounded to the number of decimals the caller passes, with a /// . separator: FromDouble(100, 2) is 100.00.

The driver only wrote the prompt into the transcript as a notexecuted step and moved on 250 ms later: no window, no wait. The steps that read the toggle's effect ran at once, so the re-enable epochs, the failed enable, the independent disable of the release gate and both Q16 checks were NotExecuted in every run, even with the operator at the keyboard. A toggle is now an operator step. The driver shows the prompt in a window that does not block Cheat Engine, with a Skip button, and waits up to 90 seconds, one check per tick, for the toggle's effect: the plugin's exported function (the harness's status, Plugin A's or B's identity) is gone after a disable and back after an enable. The enable that must fail (Configure throws) has no observable effect, so its window also offers Done, and the operator's confirmation ends it. The effect or the confirmation is recorded ok; Skip, closing the window or no action in time is recorded notexecuted with the prompt; a window that cannot be created is recorded error, and the session goes on. The driver still never touches the settings form, and five such waits fit a session's 10 minutes. AfterOperator takes every toggle a check depends on and runs the check only when each was recorded ok; otherwise it is NotExecuted with what the driver recorded. Q06 now waits for the disable, the failing enable and the enable after the fault, Q05 for the disable and the re-enable. The S0 spike's toggle receipts pass when the driver saw them done. The reviewed driver text, the session plans, the evaluator and spike tests and the Client.Tests README follow. --- .../LiveQualification/EvaluatorTests.cs | 36 +++- .../LiveQualification/LiveSandboxSession.cs | 11 +- .../LiveSandboxSessionTests.cs | 17 +- .../LiveQualification/LuaDriverScript.cs | 187 +++++++++++++++--- .../LiveQualification/LuaDriverScriptTests.cs | 100 +++++++++- .../LiveQualification/ScenarioEvaluators.cs | 28 +-- .../LiveQualification/SessionEvidence.cs | 30 ++- .../LiveQualification/SessionPlanTests.cs | 39 +++- .../LiveQualification/SessionPlans.cs | 24 ++- tests/CheatEngine.Client.Tests/README.md | 23 ++- 10 files changed, 411 insertions(+), 84 deletions(-) diff --git a/tests/CheatEngine.Client.Tests/LiveQualification/EvaluatorTests.cs b/tests/CheatEngine.Client.Tests/LiveQualification/EvaluatorTests.cs index 23ffc22..8a27c53 100644 --- a/tests/CheatEngine.Client.Tests/LiveQualification/EvaluatorTests.cs +++ b/tests/CheatEngine.Client.Tests/LiveQualification/EvaluatorTests.cs @@ -5,8 +5,8 @@ namespace CheatEngine.Client.Tests.LiveQualification;

SessionPlanTests only proved that every step a check reads exists, never the reverse. And Q32's target-change-observed passed for any process id above zero, so a Client that kept reporting A after Cheat Engine selected B would have passed it. S3 now has, under Q26 (the value scan exit criteria already name the target change), a session that has ended with RefusedTargetChanged and manual recovery once the Client observes B, a release on B that makes no Cheat Engine call and returns that ending refusal again, and no session on a file opened as a process (TargetIdentityUnavailable). Q35 requires RefusedTargetChanged on the patch lease and the same repeated refusal on B; whether the symbol still resolves there is recorded, not required, since Cheat Engine's registered symbols across a process switch are not a Client fact. Q30.a's release on B now expects that repeated refusal too, instead of AlreadyReleased, which a repeated release no longer reports. Q26 moves to S1 and S3, and the S3 live fact carries its trait. S3 calls runtime on A before the switch. Q32 compares each process the driver selected (opened-process-a, -b, -a-again) with the process the next runtime reports, and requires the selection epoch to grow at each switch, so a stale process id or epoch fails. SessionPlanTests removes each driver step in turn and requires that every step whose absence changes no check verdict is listed as reviewed setup. It found two more unread steps, now read: the S1 allocation state (Q30.a requires an active lease before its release) and the S5 disable of Plugin B (Q09 requires its functions gone). EvaluatorTests cover the stale process and epoch cases and the S3 release checks. --- .../LiveQualification/EvaluatorTests.cs | 55 +++++++++ .../LiveQualification/LiveSessionTests.cs | 1 + .../LiveQualification/ScenarioCatalog.cs | 2 +- .../LiveQualification/ScenarioEvaluators.cs | 108 +++++++++++++++--- .../LiveQualification/SessionEvidence.cs | 7 ++ .../LiveQualification/SessionPlanTests.cs | 55 ++++++++- .../LiveQualification/SessionPlans.cs | 1 + tests/CheatEngine.Client.Tests/README.md | 10 +- 8 files changed, 221 insertions(+), 18 deletions(-) diff --git a/tests/CheatEngine.Client.Tests/LiveQualification/EvaluatorTests.cs b/tests/CheatEngine.Client.Tests/LiveQualification/EvaluatorTests.cs index 8a27c53..67fc2f1 100644 --- a/tests/CheatEngine.Client.Tests/LiveQualification/EvaluatorTests.cs +++ b/tests/CheatEngine.Client.Tests/LiveQualification/EvaluatorTests.cs @@ -1,3 +1,4 @@ +using System.Globalization; using System.Runtime.Versioning; using System.Text; @@ -96,6 +97,60 @@ public void ARefusedReleaseAfterATargetChangeEndsTheLease() """{"lease":{"released":true,"requiresManualRecovery":false},"lastRelease":{"kind":"Released"}}"""))).Status); } + [Theory] + [InlineData(4243, 2, true)] + [InlineData(4242, 2, false)] + [InlineData(4243, 1, false)] + [InlineData(4243, 3, false)] + public void ATargetSwitchReportsTheSelectedProcessWithALaterEpoch(int processOnB, int epochOnB, bool passes) + { + QualificationCheck check = Check("Q32", "S3", "target-change-observed"); + static string Runtime(int processId, int epoch) + { + return "{\"ok\":true,\"process\":{\"processId\":" + processId.ToString(CultureInfo.InvariantCulture) + + ",\"selectionEpoch\":" + epoch.ToString(CultureInfo.InvariantCulture) + "}}"; + } + + CheckResult result = check.Evaluate(Evidence(("opened-process-a", "4242"), ("runtime-on-a", Runtime(4242, 1)), + ("opened-process-b", "4243"), ("runtime-on-b", Runtime(processOnB, epochOnB)), + ("opened-process-a-again", "4242"), ("runtime-back-on-a", Runtime(4242, 3)))); + + Assert.Equal(passes ?

Q05 identification-line passed on any debug output line that named the harness, a load failure included, and called the line's format a spike fact. CheatEngine.SDK 2.0.0 fixes it: LoadIdentification writes one "CheatEngineSdkIdentification: " line per enable when CHEATENGINE_SDK_IDENTIFY_ON_ENABLE=1, which the runner sets, through DebugOutputLogSink's "[CheatEngine.SDK.Hosting] Information: " prefix, and its plugin.assembly field is " ". The check now requires such a line whose plugin.assembly is the harness; with no debug output at all it is NotExecuted. Q40 loaded-client-version, a release-gate check, applied All() to the Client assemblies of the status observation, so an observation with none passed. It now requires both the Hosting and the Core assembly, each with the packed version alone or with build metadata. Q43 searched the whole lifecycle sink with a substring match, so once the operator toggles run it could pass on an earlier disable, and "resource.disposed" matched "resource.disposed.unused". Worse, S2 deleted the fault switch after the Configure fault, so every later enable ran without the ModuleOnDisabling fault Q43 reads. The checks now read the last enable that recorded a disable, from its configure ledger entry to the next, the closeCE disable or else the operator's last, and match whole stages; S2 writes ModuleOnDisabling back instead of deleting the switch (restore-disabling-fault). Q44's harness field refusedBeforeAnyHostCall was computed from the two fields beside it and asserted a host behaviour nothing observed. It is gone; the check reads the missing service and the Missing policy gate. The harness README records the deviation from the plan: without the opt-in there is no client to call, so the Client's own NotStarted refusal is proven at C1 only (AutoAssemblerClientTests). Q19's worker probe caught only CheatEngineOperationException, but a refused generated registration now throws the exception of its failure's kind (CheatEngineInvalidStateException from a worker). The probe therefore catches CheatEngineClientException, so it records the failure that direct-register-refused reads, not an exception name. EvaluatorTests cover each case: a mention that is no identification line, an empty assemblies array, an earlier faulty disable followed by a clean one, an unused-resource stage, and a satisfied policy gate. --- .../QualificationScenarios.Host.cs | 3 +- .../QualificationScenarios.cs | 5 +- .../README.md | 9 +- .../LiveQualification/EvaluatorTests.cs | 100 +++++++-- .../LiveQualification/ScenarioEvaluators.cs | 189 +++++++++++++++--- .../LiveQualification/SessionPlanTests.cs | 16 +- .../LiveQualification/SessionPlans.cs | 18 +- tests/CheatEngine.Client.Tests/README.md | 15 +- 8 files changed, 287 insertions(+), 68 deletions(-) diff --git a/tests/CheatEngine.Client.LivePlugin.Qualification/QualificationScenarios.Host.cs b/tests/CheatEngine.Client.LivePlugin.Qualification/QualificationScenarios.Host.cs index c88ed8f..77077c8 100644 --- a/tests/CheatEngine.Client.LivePlugin.Qualification/QualificationScenarios.Host.cs +++ b/tests/CheatEngine.Client.LivePlugin.Qualification/QualificationScenarios.Host.cs @@ -202,8 +202,9 @@ internal void Start(QualificationSession.ActiveClient active) _module.Register(); _registered = true; } - catch (CheatEngineOperationException exception) + catch (CheatEngineClientException exception) { + // A refused registration throws the exception of its failure's kind: InvalidState from a worker. _registerFailure = exception.Failure; } catch (Exception exception) when (exception is not OutOfMemoryException) diff --git a/tests/CheatEngine.Client.LivePlugin.Qualification/QualificationScenarios.cs b/tests/CheatEngine.Client.LivePlugin.Qualification/QualificationScenarios.cs index 67a2b06..4018772 100644 --- a/tests/CheatEngine.Client.LivePlugin.Qualification/QualificationScenarios.cs +++ b/tests/CheatEngine.Client.LivePlugin.Qualification/QualificationScenarios.cs @@ -695,11 +695,10 @@ private static string WriteCapabilities(QualificationObservation observation, .EndObject(); if (policyRefusals && TryDescribeOptInService(active.Services, capability, out bool registered)) { - // The opt-in registers the service and satisfies the policy gate together; without it no call exists. + // The opt-in registers the service and satisfies the policy gate together; without it no call exists, so + // the Client's own policy refusal (NotStarted, no host call) cannot be observed here: it is proven at C1. observation.BeginObject("policyRefusal") .Boolean("serviceRegistered", registered) - .Boolean("refusedBeforeAnyHostCall", - !registered && evidence.Policy.State == ClientCapabilityEvidenceState.Missing) .EndObject(); } diff --git a/tests/CheatEngine.Client.LivePlugin.Qualification/README.md b/tests/CheatEngine.Client.LivePlugin.Qualification/README.md index 15cb06d..0083bb7 100644 --- a/tests/CheatEngine.Client.LivePlugin.Qualification/README.md +++ b/tests/CheatEngine.Client.LivePlugin.Qualification/README.md @@ -72,7 +72,8 @@ and tested there. without it `aa_patch` is refused and Q44 observes the policy refusal), `CECLIENT_QUALIFICATION_TABLE_ROOT` is the one allowed table root (Q34), and `CECLIENT_QUALIFICATION_LIFECYCLE_FILE` names the lifecycle receipt sink (`Harness/QualificationLifecycleSink.cs`, Q43): every lifecycle record entry and the template of every captured log - event is appended there, so the runner reads what the disable at `closeCE` did after the last Lua call. + event is appended there, so the runner reads what a disable did after the last Lua call, the operator's or the one at + `closeCE`.

RELEASING names 1.0.0 as the first release. The one-time setup gains the policy owner (the CheatEngine organization of nuget.org), NUGET_USER=AriusII, the nuget environment with its required reviewers (self-review stays allowed while one maintainer publishes) and a v* tag ruleset. Preparing a release follows the merge policy: the 1.0.0 pull request carries blame-ignored commits, so it takes a merge commit, and a dry run precedes the tag. The pack rehearsal now builds with the MinVer override too, like the qualification run, so that its assemblies carry the version of their packages. The qualification gate of the SDK 2.0.0 tuple goes through the live runner: the command, the recorded run on the committed tree, the evidence folder bound by the source digest, the release-gate scenarios (Q44 is now the refusal of an API that needs an opt-in, no longer contract-only APIs) and the scenarios that lift each experimental id. The gate is stated as a contract: a capability's qualification gate requires committed evidence for all its scenarios and stays Unknown without it, which is true before the runtime derives it from that evidence. "After a release" becomes "Next change after the release": the 1.0.0 validation baseline with the strict-mode and suppression decisions it brings, MinVer 1.1 with every lock file regenerated, [Unreleased] reopened, the NuGet badge. Publish, Verify, Re-run and the release contents are unchanged, and so is the F05 bullet, which matches the code: Client.ValueScanning composes the SDK scan sessions behind CECLIENT5001 and needs Q25 and Q26. SECURITY supports 1.0.x with CheatEngine.SDK [2.0.0, 3.0.0). ROADMAP gains a post-1.0 section: the removed domains that await SDK primitives, the SDK requests (a MemoryRecord child-count getter, a script-read status, protected chunk execution), the exit of CECLIENT5001-5004 through host qualification, LuaOptional and the deferred facade-versus-SDK benchmark (A24-26). CONTRIBUTING gives the exact per-commit test command, without the package consumption and live qualification tests, then the packed run; a merge policy (squash by default, a merge commit for a pull request that contains blame-ignored commits); the rule that every ratchet exception names the missing SDK primitive; the experimental API rule; the Shipped rule after 1.0.0; and a pointer to the live qualification procedure of the CheatEngine.Client.Tests README. The title rules follow the repository's merge settings: a squash takes the pull request title, or the commit subject of a single-commit pull request, and a merge commit keeps GitHub's "Merge pull request" subject and repeats the title in its message. .coderabbit.yaml follows: the merge policy in the title check, the 1.x compatibility rules in the API check and the Abstractions instructions, a pin check on a move to another SDK major, the ratchet wording, experimental lifts tied to committed evidence, and no docs/ path. Dependabot keeps CheatEngine.SDK out of both NuGet groups, the minor-and-patch version updates and the security updates: its update is a reviewed pin move that also raises the SDK floor the packages publish, and it would hold the other updates back. DependabotConfigurationTests pins the exclusion on every NuGet group. IssueFormTests ties the version placeholders of the forms to the Client major line, the pinned SDK and its content hash. The bug form lists the experimental APIs, and the pull request template covers the merge policy, 1.x compatibility, experimental APIs and ratchet exceptions. --- .coderabbit.yaml | 72 ++++++--- .github/ISSUE_TEMPLATE/bug_report.yml | 5 +- .github/PULL_REQUEST_TEMPLATE.md | 12 +- .github/dependabot.yml | 7 + CONTRIBUTING.md | 98 +++++++---- RELEASING.md | 152 ++++++++++++++---- ROADMAP.md | 39 ++++- SECURITY.md | 16 +- .../DependabotConfigurationTests.cs | 28 +++- .../Governance/IssueFormTests.cs | 85 +++++++++- .../README.md | 9 +- 11 files changed, 425 insertions(+), 98 deletions(-) diff --git a/.coderabbit.yaml b/.coderabbit.yaml index d0abe1e..d527f06 100644 --- a/.coderabbit.yaml +++ b/.coderabbit.yaml @@ -19,9 +19,12 @@ reviews: title: mode: "warning" requirements: >- - Pull requests are squash-merged and the title becomes the commit subject on main.

Once CheatEngine.SDK 2.0.0 detects that Cheat Engine replaced its Lua state, it refuses every Lua admission, and taking a snapshot needs one: TryGetSnapshot then fails with RuntimeChanged instead of returning the flag. This is a ratified plan deviation on A8, made before the 1.0 API freeze. - CheatEngineRuntimeLuaInfo, CheatEngineRuntimeSnapshot.Lua and the snapshot constructor's lua parameter leave the public surface and PublicAPI.Unshipped.txt, since the type held nothing else. - The runtime observation port loses its ExternalStateResetDetected member, with its production, fake and throwing implementations. The port test now pins that the port has no property at all. - The snapshot remarks and the Abstractions README say instead that a reset surfaces as RuntimeChanged failures, the snapshot's included, and as the Hosting deactivation warning (event 8). - The harness runtime() observation stops writing the field. - The test that read the SDK flag without a Lua admission now reads SdkBoundary.ExternalStateResetDetected, which the DI cleanup bridge hands to Hosting for event 8. SdkBoundary.cs is frozen after L6. Its remark said the runtime snapshot reports the flag; it now names the Hosting reader. This is a doc-only freeze exception, like the earlier SdkBoundary remarks. --- .../PublicAPI.Unshipped.txt | 13 +-------- .../CheatEngine.Client.Abstractions/README.md | 9 ++++--- .../Runtime/CheatEngineRuntimeLuaInfo.cs | 27 ------------------- .../Runtime/CheatEngineRuntimeSnapshot.cs | 26 +++++++++--------- .../Domains/IRuntimeObservationPort.cs | 9 ------- .../Domains/RuntimeClient.cs | 3 +-- .../Domains/SdkRuntimeObservationPort.cs | 3 --- .../Infrastructure/SdkBoundary.cs | 3 ++- .../CheatEngineRuntimeSnapshotTests.cs | 25 +++++------------ .../Domains/RuntimeClientTests.cs | 20 +------------- .../Domains/SdkRuntimeObservationPortTests.cs | 7 ----- .../Infrastructure/TryContractTests.cs | 10 +++++-- .../TestSupport/FakeRuntimeObservationPort.cs | 7 ----- .../QualificationScenarios.cs | 1 - 14 files changed, 37 insertions(+), 126 deletions(-) delete mode 100644 libs/CheatEngine.Client.Abstractions/Runtime/CheatEngineRuntimeLuaInfo.cs diff --git a/libs/CheatEngine.Client.Abstractions/PublicAPI.Unshipped.txt b/libs/CheatEngine.Client.Abstractions/PublicAPI.Unshipped.txt index 076c6e6..cca38c0 100644 --- a/libs/CheatEngine.Client.Abstractions/PublicAPI.Unshipped.txt +++ b/libs/CheatEngine.Client.Abstractions/PublicAPI.Unshipped.txt @@ -380,11 +380,6 @@ CheatEngine.Client.Results.LeaseReleaseOutcome.Kind.get -> CheatEngine.Client.Re CheatEngine.Client.Results.LeaseReleaseOutcome.LeaseReleaseOutcome() -> void CheatEngine.Client.Results.LeaseReleaseOutcome.LeaseReleaseOutcome(CheatEngine.Client.Results.LeaseReleaseKind kind, CheatEngine.Client.Results.CheatEngineHostEffect hostEffect) -> void CheatEngine.Client.Results.LeaseReleaseOutcome.RequiresManualRecovery.get -> bool -CheatEngine.Client.Runtime.CheatEngineRuntimeLuaInfo -CheatEngine.Client.Runtime.CheatEngineRuntimeLuaInfo.CheatEngineRuntimeLuaInfo() -> void -CheatEngine.Client.Runtime.CheatEngineRuntimeLuaInfo.CheatEngineRuntimeLuaInfo(bool externalStateResetDetected) -> void -CheatEngine.Client.Runtime.CheatEngineRuntimeLuaInfo.Equals(CheatEngine.Client.Runtime.CheatEngineRuntimeLuaInfo other) -> bool -CheatEngine.Client.Runtime.CheatEngineRuntimeLuaInfo.ExternalStateResetDetected.get -> bool CheatEngine.Client.Runtime.CheatEngineRuntimePlatformInfo CheatEngine.Client.Runtime.CheatEngineRuntimePlatformInfo.CheatEngineBitness.get -> CheatEngine.SDK.Engine.Runtime.PointerSize CheatEngine.Client.Runtime.CheatEngineRuntimePlatformInfo.CheatEngineRuntimePlatformInfo() -> void @@ -403,10 +398,9 @@ CheatEngine.Client.Runtime.CheatEngineRuntimePlatformInfo.TargetIsAndroid.get -> CheatEngine.Client.Runtime.CheatEngineRuntimeSnapshot CheatEngine.Client.Runtime.CheatEngineRuntimeSnapshot.Capabilities.get -> CheatEngine.Client.Runtime.ClientCapabilities!

Nothing here has run live; the L25 run exercises the harness. --- .../QualificationPlugin.cs | 37 +++++++++++-------- .../QualificationScenarios.cs | 2 +- .../QualificationSession.cs | 20 +++++++++- .../SingleFileSuppressionTests.cs | 16 +++++--- 4 files changed, 53 insertions(+), 22 deletions(-) diff --git a/tests/CheatEngine.Client.LivePlugin.Qualification/QualificationPlugin.cs b/tests/CheatEngine.Client.LivePlugin.Qualification/QualificationPlugin.cs index aee5713..80a916a 100644 --- a/tests/CheatEngine.Client.LivePlugin.Qualification/QualificationPlugin.cs +++ b/tests/CheatEngine.Client.LivePlugin.Qualification/QualificationPlugin.cs @@ -1,5 +1,3 @@ -using System.Diagnostics.CodeAnalysis; - using CheatEngine.Client; using CheatEngine.Client.Extensions.DependencyInjection; using CheatEngine.Client.Hosting; @@ -28,25 +26,17 @@ public sealed class QualificationPlugin : CheatEngineClientPlugin /// The name Cheat Engine shows in Edit > Settings > Plugins. internal const string DisplayName = "CheatEngine.Client Qualification Plugin"; - /// The folder the plugin was loaded from, where the runner writes the fault switch. - [UnconditionalSuppressMessage("SingleFile", "IL3000:Avoid accessing Assembly file path when publishing as a single file", - Justification = "The harness is a managed-hostfxr plugin loaded from its bundle folder and is never published as a single file; an empty location reads as no fault switch and no bridge.")] - internal static string?

The DI codec example registers a codec with AddSingleton, TCodec>() and passes it through the request; the Hosting module example defines its module and shows the IdentifyOnEnable module initializer with its CA2255 reason. - Core: a plugin-author page (never reference it, what it guarantees, the cost of Cheat Engine calls, the diagnostic events). Its implementation notes, and the contribution sections of the Abstractions and Fluent READMEs, move to CONTRIBUTING under a new "Package READMEs and implementation notes" section; the governance text of the previous commit is unchanged. - The root README gains separate requirement tables for plugin projects and for building the repository, and its capability table now carries the capability-table markers, so CapabilityDocumentationTests checks it (AUD-19). Its build section points to CONTRIBUTING instead of repeating it. Pending documentation items: the Abstractions diagnostics paragraph names events 1000 to 1800, including the Auto Assembler warning 1800; the CECLIENT5003 line over 120 columns is rewrapped; the Q09 sentence of the DI and Hosting READMEs no longer uses audit jargon; the Repository.Tests README lists the Capabilities, SourcePolicy and Sonar tests. No README contained a "v0.1" title any more. Every file of SdkPinTests.ProseLocations still names CheatEngine.SDK 2.0.0, and no line claims a host qualification.

The qualification gate comes from the internal `HostQualificationGate`: it is `Satisfied` only when the host +evidence this build embeds (`HostQualificationEvidence`, empty until a live run is recorded, and excluded from the +qualified source digest) names exactly the loaded CheatEngine.SDK package, which must be the reviewed one, Cheat Engine +7.7.0.10621 and the supported host profile, when the observed host is Cheat Engine 7.7.0.10621 64-bit on Windows with a +local target of an architecture the run covered, when the evidence names this Client version, and when every scenario +of the capability passed without a waiver; otherwise it is `Unknown` and names the first condition that does not hold. + +The package gate compares the CheatEngine.SDK identity embedded in the Core assembly at build time (version, source +commit and NuGet content hash, as `AssemblyMetadata`, taken from the locked and restored package, and the supported +major of `eng/CheatEngineSdk.props`) with the informational version of the `CheatEngine.SDK.Engine` assembly actually +loaded; it reads assembly attributes only. Its reason says whether the loaded assembly is exactly the reviewed package, +a distinction the qualification gate needs (a receipt covers only the tuple it was produced with). A build that cannot +embed that identity fails with `CHEATENGINECLIENT9050`. + +**Instructions** (`CECLIENT5003`): the internal `AssemblyClient` runs each call in one dispatched callback behind one +`LuaAdmission`, observes the instruction profile once (`InstructionProfiles.TryObserveCurrent`), refuses an address +wider than that profile before any instruction function of Cheat Engine is called, and passes the same profile to +`SdkInstructionPort` (`InstructionAssembler`, `InstructionDisassembler`, `InstructionNavigator` and the counted +`TargetMemory.TryReadBytes`). Assembly uses a 16-byte buffer bounded by `MemoryResourceLimits.MaximumReadBytes`, with +one retry at the exact length the SDK reports, and refuses an empty result; a disassembly reads its bytes from target +memory for the reported length, between two SDK target checks, and never parses the disassembler's byte column. +`InstructionMapping` maps every `InstructionOperationStatus` totally, and a step that follows an earlier instruction +call of the same Client call is never `NotStarted`. + +**Auto Assembler patches** (`CECLIENT5004`): the internal `AutoAssemblerClient` is registered only by +`EnableAutoAssemblerPatches()`, which also sets `CoreClientPolicy.EnableAutoAssemblerPatches`, and it refuses every call +without that policy (`CapabilityUnavailable`, `NotStarted`, no dispatch). Its only Cheat Engine calls go through +`SdkAutoAssemblerPort` (`AutoAssemblerPatcher.TryApplyWithOutcome` and `TryCheck` with bounded options, behind +`LuaAdmission`); `AutoAssemblerMapping` maps every SDK outcome category totally. The applied patch is handed to +`AutoAssemblerPatchLease`, a target-bound `HostResourceLease` registered inside the same dispatched callback under the +selection of the process incarnation the SDK bound the patch to (`ITargetSelectionBinder`, as for allocations and value +scans), which releases through the SDK owner's `ReleaseWithTargetOutcome` and never rebuilds a `[DISABLE]` section; a +refused registration is reported by `LeaseRegistration`. That owner consumes its disable information on every release +status, so `AutoAssemblerMapping.ToReleaseOutcome` reports `NotInvoked` as `RefusedRuntimeChanged` (manual recovery) +instead of the shared retryable `CleanupUnavailable`. + +#### Runtime facts, target selection and pointer width + +Every runtime and target fact is a read-only CheatEngine.SDK call through `SdkRuntimeObservationPort`: +`RuntimeObservations.TryObserveRuntimeInfo` for the snapshot, `RuntimeHostOperations` for the host facts, +`RuntimeProcessOperations` (`ObserveCurrent`, `ObserveTargetArchitecture`, `TryGetConfiguredPointerSize`) for the target +and `TargetSelection` (`ObserveCurrent`, `ValidateCurrent`) for its identity; the architecture ratchet keeps the port +to that exact read-only list (Q45). The SDK reads the selected process identifier before and after the target facts and +reads none of them when no target, or a file opened as a process, is selected. The SDK reports every outcome as a +status, never through Lua error text, and `RuntimeObservationMapping` maps each status value explicitly. When the +aggregate snapshot cannot be produced, the Client reads the host facts on their own, and each fact alone when that +fails, and observes the target through `TargetArchitectureObserver`. A target fact that raises or is malformed narrows +the observation to the PID, the bitness and the configured pointer size, which it keeps only when two selected-PID +reads agree; the ISA, the backend and the ABI then stay `Unknown`. + +The one call that changes Cheat Engine's selection is `RuntimeProcessOperations.SelectAndObserve`, behind +`SdkProcessSelectionPort`, and `ProcessClient.TryAttach` is its only caller (architecture ratchet). A refused attach +keeps the SDK status as its kind with an `Unknown` host effect, and the selection is observed again after a refusal, so +the epoch follows what Cheat Engine now selects. For a local process the selection identity is the PID and its +incarnation, the creation time CheatEngine.SDK observed together with the local backend; a known incarnation is checked +with `TargetSelection.ValidateCurrent`. `ProcessClient` advances the target-selection epoch, and ends the target-bound +leases of the earlier selection, when the PID changes, when the same PID denotes another incarnation, when a known +backend, ISA or process width changes to another known value, or when Cheat Engine reports no target or a file opened +as a process; a fact that is transiently unknown keeps the epoch and the last known value. + +Every pointer read and write goes through the width-qualified `TargetMemory.TryReadPointer` and `TryWritePointer` +overloads with the observed bitness, and every `MemoryAccessFailure` reaches the caller through +`MemoryAccessFailureMapping`, value by value and never as text. + +#### Address List records and symbols + +Every trusted table load that reaches Cheat Engine advances the table generation of the activation inside the +dispatched load; each snapshot is judged by the generation read when it was copied. Table files load and save through +CheatEngine.SDK's `CheatTableFiles`, only after the `AllowedTableRoots` policy admitted the path, and `TableMapping` +classifies its `LuaOperationStatus` value by value; the Client binds no Cheat Engine global itself. Delete, parent +assignment and activation are CheatEngine.SDK `AddressListMutations` commands (`Delete`, `SetParent` with the Client's +explicit traversal limit of 4096 records, `SetActive`), also classified by `TableMapping`; the record is copied again +after a completed command and a failed copy is never merged with the command's result. Snapshots read the record +through CheatEngine.SDK's typed `MemoryRecord` getters (`TryGetActive`, `TryGetAsync`, `TryGetAsyncProcessing`, +`TryGetScript`, `TryGetOffsetCount`); the child count alone is still Cheat Engine's `Count` property, because the SDK +has no child-count getter and `TryGetChild` cannot tell a missing child from a failed read (`FrozenLuaUsage`, +`AwaitingSdkPrimitive`). `TryGetScript` cannot tell a record without a script from a failed read either; a getter that +tells them apart is awaited from the SDK. A failed `Create` is rolled back once through `AddressListMutations.Delete`. + +Symbol registration refuses a name that already resolves (`EngineInspection.ResolveAddress`), then registers through +CheatEngine.SDK's ownership coordinator (`SymbolRegistry.TryRegisterOwned`) and registers the lease with the +activation in the same main-thread callback. + +#### AOB scans + +`PatternScanner` runs a request without a module or range as one global Cheat Engine `AOBScan`. A module and/or range +request resolves the module, builds the SDK's `AobScanBounds` (the module intersected with the range, whose inclusive +end becomes `End + pattern length`, checked and saturated) and, when the port's `TargetSelection.ObserveCurrent` +observation qualifies the target, runs the stable `AobScanner.TryScanWithinBounds` overload with a destination of +`min(MaximumResults + 1, ScanResourceLimits.MaximumPatternMatches)` addresses and the caller's token. An unqualified +target, or a session the SDK could not create or attach to one target, falls back to the global scan with the module +and range applied while copying; the fallback never reports a verified target identity. Both routes copy through one +scope predicate (`PatternScanner.IsInsideRequest`), copy at most `ScanResourceLimits.MaximumPatternMatches - 1` +addresses, and send the empty protection text for the default filter. +`tests/CheatEngine.Client.Benchmarks/AobRouteComparisonBenchmarks.cs` compares the Client cost of the two routes over a +fake port, and `PatternScannerMaterializationBenchmarks.cs` measures the copy cost alone; the Cheat Engine scan cost is +a live-host measurement. + +The SDK owner of the result list is handed to the Client wrapper through `OwnershipHandoff`, so a failure between +acquisition and publication releases the Cheat Engine list exactly once; when that release is not confirmed, the typed +`OwnershipHandoffException` carries its kind and the scan fails with `CleanupUnconfirmed`. The scanner then releases +the list exactly once on every path, inside the dispatched callback, through the SDK owner's never-throwing +`ReleaseWithOutcome`, mapped with `SdkReleaseOutcomes`. The AOB port calls `AobScanner.TryScanOutcome` with its target +context, and `AobScanMapping` classifies every outcome from SDK outcome values only, never from Cheat Engine or Lua +error text. + +#### Leases and release outcomes + +Every Client lease derives from the internal `HostResourceLease`, which implements `ICheatEngineLease` once: the +release runs on Cheat Engine's main thread through the activation dispatcher, attempts are serialized and idempotent, +`Dispose` never throws, and each attempt is logged with its operation name, kind and effect only (event 1701). A lease +registers with the activation registry and, when it is bound to the selected target, with the target-selection lifetime +too. A complete outcome unregisters it; a retryable or incomplete one keeps it registered, and the activation drain +retries or reports it (Q43). + +`SdkReleaseOutcomes` maps the CheatEngine.SDK release statuses totally (`TargetReleaseStatus`, +`SymbolRegistrationReleaseKind`; an unknown value is `Unknown` with an unknown effect) and combines the parts of one +lease by keeping the outcome that leaves the most to do. The Lua module lease (`Lua.Release`) maps the kind its module +reports with `LuaModuleReleaseMapping`; `LuaRegistrationReleaseKind` is mapped by the generated Lua registrar, which +owns the SDK registration lease (see the generator README). Every lease release is named `.Release`, and every +failure operation `.` after the public call that produced it (`OperationNameTests`). + +#### SDK boundary and the Try contract + +Every Client-internal CheatEngine.SDK call (ports, `TargetMemory`, `EngineInspection`, `AobScanner`, Address List +access and mutations, `CheatTableFiles`, protected Lua execution) runs behind `SdkBoundary`: an SDK exception becomes a +classified `CheatEngineFailure` by exception type and the SDK's own failure category, never by message text. Client +lifecycle exceptions are never translated, and an SDK fault observed after the activation ended is reported as +`CheatEngineActivationExpiredException`. Lua work that Core runs itself asks for its admission through `LuaAdmission` +(`LuaRuntime.TryAcquireOperationWithOutcome`), and a refusal is classified from the SDK's admission status. A +CheatEngine.SDK call that acquires its own admission (`AddressListMutations`, `CheatTableFiles`, `SymbolRegistry`, +`TargetMemory`, scans) raises a plain `InvalidOperationException` when it is refused, which `SdkBoundary` reports as +`OperationRejected` with `Unknown`, unless the activation ended or the SDK detected an external Lua state reset +(`RuntimeChanged`). Consumer-supplied code (dispatcher callbacks, codecs, typed Lua operations) is never wrapped. + ## Evidence and qualification levels State the qualification level of every validation you report: **C0** static contract, **C1** managed tests or test diff --git a/README.md b/README.md index a96027f..1ab06a2 100644 --- a/README.md +++ b/README.md @@ -10,7 +10,7 @@ [![.NET 10](https://img.shields.io/badge/.NET-10.0-512BD4?style=flat-square&logo=dotnet&logoColor=white&labelColor=24292f)](https://dotnet.microsoft.com/download/dotnet/10.0) [![Windows x64](https://img.shields.io/badge/platform-Windows%20x64-0078D4?style=flat-square&labelColor=24292f)](#requirements) -[Quick start](#quick-start) · [Lifecycle](#the-plugin-lifecycle) · [Packages](#packages-and-direct-sdk-reference) · [Capabilities](#10-capability-status) · [Contributing](CONTRIBUTING.md) +[Quick start](#quick-start) · [Lifecycle](#the-plugin-lifecycle) · [Packages](#packages-and-direct-sdk-reference) · [Capabilities](#capability-status) · [Contributing](CONTRIBUTING.md) @@ -54,13 +54,27 @@ surface reviewable: high-level APIs remain fluent for consumers while the Core r ## Requirements -| Requirement | Baseline | -|-----------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| -| .NET SDK | 10.0.401 exactly (`global.json` `rollForward: disable`); install it with `winget install Microsoft.DotNet.SDK.10 --version 10.0.401` | -| Target framework / language | `net10.0` / C# 14 | -| Cheat Engine host | 7.7, Windows x64 | -| Plugin form | Framework-dependent managed plugin output folder | -| SDK package | `CheatEngine.SDK` 2.0.0, pinned in `eng/CheatEngineSdk.props`; the Client declares `[2.0.0, 3.0.0)`: a 3.x SDK fails the build with `CECLIENT017`, a version below 2.0.0 fails the restore with `NU1605` | +A plugin project that consumes the packages needs: + +| Plugin project requirement | Value | +|---|---| +| Target framework | `net10.0` | +| Language | C# 14 (`14.0`) | +| .NET SDK | 10.0.401 or later: the Lua generator packed in Hosting is compiled against Roslyn 5.9.0 (CS9057 below it) | +| Platform | Windows x64; `PlatformTarget` is `x64` or `AnyCPU` | +| Cheat Engine host | 7.7.0.10621 x64 (`cheatengine-x86_64.exe`), loading the plugin through its managed .NET host | +| Plugin form | Framework-dependent managed plugin output folder, never a Native AOT DLL | +| `CheatEngine.SDK` | A direct `PackageReference` in `[2.0.0, 3.0.0)`: a 3.x SDK fails the build with `CECLIENT017`, a version below 2.0.0 fails the restore with `NU1605` | + +Building this repository needs: + +| Repository build requirement | Value | +|---|---| +| Operating system | Windows x64 | +| .NET SDK | 10.0.401 exactly (`global.json` `rollForward: disable`); install it with `winget install Microsoft.DotNet.SDK.10 --version 10.0.401` | +| `CheatEngine.SDK` | 2.0.0, pinned in `eng/CheatEngineSdk.props` and in every committed lock file | +| Tools | PowerShell 7.4 or later and Git, to run the CI checks locally ([CONTRIBUTING](CONTRIBUTING.md#prerequisites)) | +| Cheat Engine | Only for the opt-in live qualification tests, never for an ordinary build or test run | Cheat Engine remains the compatibility authority.

A snapshot never loads a -driver, runs remote code, changes the target, loads a table or allocates target memory; the -architecture ratchet keeps the port to that exact read-only list (Q45). The SDK reads the selected -process identifier before and after the target facts and reads none of them when no target, or a -file opened as a process, is selected: with no target Cheat Engine reports the facts of an x64 -target. The ISA is the SDK's own derivation from the x86 and ARM family facts with the 64-bit fact, -never a Client inference. - -The SDK reports every outcome as a status, never through Lua error text, and -`RuntimeObservationMapping` maps each status value explicitly. When the aggregate snapshot cannot be -produced (a file opened as a process, a target change, or a global that raised or returned a -malformed value), the Client reads the host facts on their own, and each fact alone when that fails, -and observes the target through `TargetArchitectureObserver`. A target fact that raises or is -malformed narrows the observation to the PID, the bitness and the configured pointer size, which it -keeps only when two selected-PID reads agree; the ISA, the backend and the ABI then stay `Unknown`. -`IProcessClient` returns a status that establishes no target with its own kind: `TargetChanged`, -`TargetIdentityUnavailable` for a file opened as a process, `CapabilityUnavailable` for an absent -global, `LuaError`, `InvalidHostResult`. - -The one call that changes Cheat Engine's selection is `RuntimeProcessOperations.SelectAndObserve`, -behind `SdkProcessSelectionPort`, and `ProcessClient.TryAttach` is its only caller (architecture -ratchet). A normal return of `openProcess` is not success by itself: the SDK reads the selected PID -again, and a refused attach keeps the SDK status as its kind (`OperationRejected` for an -unconfirmed selection, `TargetNotAttached`, `TargetIdentityUnavailable`, `TargetChanged`, -`CapabilityUnavailable`, `LuaError`, `InvalidHostResult`) with an `Unknown` host effect. The -selection is observed again after a refusal, so the epoch follows what Cheat Engine now selects. - -Cheat Engine's selected target is ambient. For a local process the selection identity is the PID -and its incarnation, the creation time CheatEngine.SDK observed together with the local backend; a -known incarnation is checked with `TargetSelection.ValidateCurrent`. `ProcessClient` advances the -target-selection epoch, and ends the target-bound leases of the earlier selection (CheatEngine.SDK -refuses their release, see "Leases and release outcomes"), when the PID changes, when the same PID -denotes another incarnation, when a known backend, ISA or process width changes to another known -value, or when Cheat Engine reports no target or a file opened as a process; a fact that is -transiently unknown, including an incarnation that cannot be read, keeps the epoch and the last -known value. Like the SDK, the Client cannot see a selection that changed and changed back between -two observations (A-B-A). A CEServer target or a target whose backend is not established has no -incarnation and no local metadata: local process name and path come from the operating system and -describe local processes only. - -Codecs use the target bitness (`targetIs64Bit`, the width `readPointer` follows), never the plugin's -own width. Every pointer read and write goes through the width-qualified `TargetMemory.TryReadPointer` -and `TryWritePointer` overloads with that observed bitness, so CheatEngine.SDK refuses a value that -does not fit a 32-bit target instead of truncating it. When the SDK reports that Cheat Engine's -configured pointer size differs from the bitness (`ConfiguredPointerSizeDiffersFromBitness`), or when -the bitness is unknown, the Client's own pointer-typed operations are refused before any memory -access (`NotStarted`: `OperationRejected` for a mismatch, `InvalidState` for a selected target -without a bitness); the configured size is exposed as a fact to custom codecs. A width that cannot -be observed keeps the kind of the status the SDK reported; only an observed "no process selected" is -`TargetNotAttached`. A pointer chain on a 32-bit target also refuses a base address, or an address it -computes by adding an offset, above 4 GiB, because the SDK qualifies only the pointer values it -reads. - -Every `MemoryAccessFailure` the SDK reports reaches the caller through `MemoryAccessFailureMapping`, -value by value and never as text: see the table in the Abstractions README. - -Cost: every `ReadPrimitive

A batch pays this once for all its -items, so hot pointer-read loops should use batches or explicit 32/64-bit integer reads. - -## Address List records and symbols - -Every trusted table load that reaches Cheat Engine advances the table generation of the activation -inside the dispatched load, on Cheat Engine's main thread; a record identifier handed out before it -is refused with `InvalidState` (checked before dispatch and again inside the dispatched call) until -a new snapshot observes it. Each snapshot is judged by the generation read when it was copied, so a -snapshot copied before a concurrent load never hands out current identifiers. Table files load and save through -CheatEngine.SDK's `CheatTableFiles`, only after the `AllowedTableRoots` policy admitted the path; its -`LuaOperationStatus` is classified value by value by `TableMapping`, and the Client binds no Cheat Engine global -itself. Delete, parent assignment and -activation are CheatEngine.SDK `AddressListMutations` commands (`Delete`, `SetParent` with the Client's explicit -traversal limit of 4096 records, `SetActive`), classified value by value by `TableMapping`; the record is copied again -after a completed command and a failed copy is never merged with the command's result. While a trusted load runs, -CheatEngine.SDK refuses those commands issued from the main thread (`TableLoadInProgress`), and the Client refuses -creation, update and selection, which have no SDK command, the same way before any Cheat Engine call. `SetActive` reads the record's -state before and after one setter call and reports applied, unchanged, refused by the host, pending or indeterminate; it -never retries, and a pending activation succeeds with a snapshot whose `IsAsyncProcessing` is `true`. Snapshots read the -record through CheatEngine.SDK's typed `MemoryRecord` getters (`TryGetActive`, `TryGetAsync`, `TryGetAsyncProcessing`, -`TryGetScript`, `TryGetOffsetCount`); the child count alone is still Cheat Engine's `Count` property, because the SDK has -no child-count getter and `TryGetChild` cannot tell a missing child from a failed read. `TryGetScript` cannot tell a -record without a script from a failed read either, so `Content.Script` is `null` in both cases and a failed read never -fails the snapshot; a getter that tells them apart is awaited from the SDK, like the child-count getter. A failed `Create` is rolled back once through `AddressListMutations.Delete`. -Symbol registration refuses a name that already resolves (`EngineInspection.ResolveAddress`), then -registers through CheatEngine.SDK's ownership coordinator (`SymbolRegistry.TryRegisterOwned`) and -registers the lease with the activation in the same main-thread callback. The lease release -delegates to the SDK lease, which unregisters the name only when it still resolves to the leased -address and no newer coordinator registration superseded it (a replaced name is left in place); -both checks are best effort, not atomic.

ReadmeSnippetCompilationTests joins the package consumption tests (Category=PackageConsumption, PackagedClientFeedFixture's serial collection). For the README that each packed package publishes, read from the archive, and for the repository README, it compiles every csharp block as one plugin project against the packed packages: the documented CheatEngine.Client, CheatEngine.SDK and Microsoft.Extensions.Configuration.Json references (the version the packed template stamps), Nullable, ImplicitUsings and warnings as errors, plus the Hosting plugin profile checks when a block declares a [CheatEnginePlugin] type. Each block is written to README.L.cs so that a compiler error names the README line of its block. TheUmbrellaReadmeShowsACompiledPlugin keeps a compiled plugin on the CheatEngine.Client page. ReadmeCodeBlocks parses fences as CommonMark delimits them. A C# block labelled cs or c# is refused rather than silently skipped, and a csharp nocompile block needs its reason on the line right above its opening fence (). ReadmeCodeBlocksTests proves these rules on fixed Markdown without packages, so both CI legs run them. No README uses nocompile today.

It replaces the prose list of the plugin profile checks and names the skip properties. - Every diagnostic of the targets now carries a help link to its row: the Error and Warning elements through HelpLink, and the inline tasks (plugin type check, deployment) through a new HelpLink parameter and the TaskLoggingHelper.LogError overload that takes one. The link is one private property, _CheatEngineClientHelpLink, composed in steps to keep each line under 120 columns. Codes, conditions and messages are unchanged. - ConsumerDiagnosticCatalogTests (Repository.Tests, source scan) proves that the emitted codes are exactly CECLIENT001 to CECLIENT017 and exactly the rows of the table, that each anchor appears once, that each row's Severity cell names how the targets emit its code (Error, Warning, or "Error; Warning with ..." for a code emitted as both, today CECLIENT017), that every emission links to its row, that the property resolves to the Hosting README, and that no inline task logs a code outside the recognized call shape. - ConsumerDiagnosticsTests (Category=PackageConsumption, the serial collection of PackagedClientFeedFixture) builds, against the packed packages, one plugin project per broken rule and proves that the build fails with that code and no other CECLIENT error: 002 (Hosting referenced instead of the Client), 005 (net10.0-windows), 006 (C# 13), 007 (x86), 008 (entry point off without the manual bootstrap acknowledgement), and the deployment checks 011, 012, 013 and 015, which also leave the deployment folder empty. 001 and 017 keep their existing smoke facts. The root and CheatEngine.Client READMEs link the table, and the test READMEs describe both classes. --- README.md | 3 +- libs/CheatEngine.Client.Hosting/README.md | 54 ++-- .../CheatEngine.Client.Hosting.targets | 50 +++- src/CheatEngine.Client/README.md | 2 +- .../ConsumerDiagnosticCatalogTests.cs | 236 ++++++++++++++++++ .../README.md | 6 + .../Packaging/ConsumerDiagnosticsTests.cs | 128 ++++++++++ tests/CheatEngine.Client.Tests/README.md | 11 + 8 files changed, 466 insertions(+), 24 deletions(-) create mode 100644 tests/CheatEngine.Client.Repository.Tests/Packaging/ConsumerDiagnosticCatalogTests.cs create mode 100644 tests/CheatEngine.Client.Tests/Packaging/ConsumerDiagnosticsTests.cs diff --git a/README.md b/README.md index 1ab06a2..046e012 100644 --- a/README.md +++ b/README.md @@ -121,7 +121,8 @@ Replace `X.Y.Z` with the CheatEngine.Client version you install; the `ceplugin` entry point and provide the native Lua bridge; NuGet transitivity is not sufficient at that host boundary.

When a later lot lifts an experimental id, the test forces the Implementation cell back to "Operational adapter", yet a stale "Experimental" in the status column would pass. CapabilityTableStatusColumnsMarkExactlyTheExperimentalApis reads the column wherever a capability table has it: a cell starts with "Experimental" exactly when the catalog row carries an experimental diagnostic id, and with "Available" (without "experimental") for every other capability. The catalog reading moves to a helper that both Implementation and status checks use; the test fails if no table has the column, so it cannot pass vacuously.

The derivation is lossy: it lowercases the name and turns each camel-case boundary and each run of other characters, non-ASCII letters included, into '_', so MyPlugin and My.Plugin both give my_plugin_status and a name without an ASCII letter or digit gives plugin_status. The template READMEs and PluginLuaFunctions say so and tell authors to rename a global that another plugin exports, since the Client's RejectExisting registration refuses it. The content project restores with RestorePackagesWithLockFile, so the first restore writes packages.lock.json with CheatEngine.SDK's content hash. That lock also records Microsoft.NET.ILLink.Tasks, which the .NET SDK adds for IsAotCompatible at the version it bundles, so a locked restore fails (NU1004) after an SDK update that bundles another version: both READMEs and the project comment tell authors to pin the exact SDK in a global.json or to regenerate the lock after an update. No lock file is committed in the content folder, and the pack keeps one restored in place out of the package; dotnet new would not copy it into a plugin anyway, since the template engine skips **/*.lock.json. LockFileTests' message now gives that reason. The template gains a skipRestore parameter (--no-restore) that conditions the restore post action, preferNameDirectory, and a .gitignore for build output and IDE state. The template package sets NoDefaultExcludes, because NuGet otherwise drops the .gitignore (NU5119). The template adds no logging provider. The content README documents the opt-in AddCheatEngineHostLog() provider, whose default sink is the Windows debug output of the Cheat Engine process, shown by an attached debugger or a debug-output viewer. TemplateInstantiationTests (PackageConsumption) prove the packed .gitignore and the absence of a lock file in the package, the pinned SDK content hash and the SDK-added Microsoft.NET.ILLink.Tasks in the instance's lock file, the derived names of six distinct project names and of three names that derive a shared global, --no-restore against a default restore, the name folder, and a build of an instance with -warnaserror, EnforceCodeStyleInBuild, the repository .editorconfig and its pinned AnalysisLevel; a style violation in the same build proves those rules are in effect. CONTRIBUTING's template smoke-test paragraph and the CheatEngine.Client.Tests README list these checks. The Native AOT probe now calls every public Fluent member against in-process fakes of IMemoryClient and IPatternScanner, checks each call's result, a builder step's before a later step replaces it, and exits with 1 on a difference. AotProbeCoverageTests reads the Fluent PublicAPI baselines and fails when a public member has fewer call sites in the probe's Exercise method for its type, comments excluded, than public signatures. The count is textual and cannot tell which overload a call binds to, so the probe gives each overload its own call with an argument of that overload's type. The CheatEngine.Client.Repository.Tests README describes the check. --- CONTRIBUTING.md | 9 +- .../CheatEngine.Client.Templates.csproj | 9 +- .../CheatEngine.Client.Templates/README.md | 27 +- .../content/CheatEngine.Plugin/.gitignore | 9 + .../.template.config/dotnetcli.host.json | 9 + .../.template.config/template.json | 88 ++++ .../CheatEngine.Plugin.csproj | 7 + .../Modules/PluginLuaFunctions.cs | 6 + .../content/CheatEngine.Plugin/Plugin.cs | 4 + .../content/CheatEngine.Plugin/README.md | 43 +- .../AotProbeFluentCalls.cs | 197 +++++++++ .../AotProbePatternScanner.cs | 47 +++ .../AotProbePointCodec.cs | 45 +++ .../AotProbeTargetMemory.cs | 381 ++++++++++++++++++ tests/CheatEngine.Client.AotProbe/Program.cs | 6 + tests/CheatEngine.Client.AotProbe/README.md | 18 +- .../LockFiles/LockFileTests.cs | 3 +- .../README.md | 4 + .../SourcePolicy/AotProbeCoverageTests.cs | 356 ++++++++++++++++ .../Packaging/TemplateInstantiationTests.cs | 236 +++++++++++ tests/CheatEngine.Client.Tests/README.md | 18 + 21 files changed, 1505 insertions(+), 17 deletions(-) create mode 100644 templates/CheatEngine.Client.Templates/content/CheatEngine.Plugin/.gitignore create mode 100644 templates/CheatEngine.Client.Templates/content/CheatEngine.Plugin/.template.config/dotnetcli.host.json create mode 100644 tests/CheatEngine.Client.AotProbe/AotProbeFluentCalls.cs create mode 100644 tests/CheatEngine.Client.AotProbe/AotProbePatternScanner.cs create mode 100644 tests/CheatEngine.Client.AotProbe/AotProbePointCodec.cs create mode 100644 tests/CheatEngine.Client.AotProbe/AotProbeTargetMemory.cs create mode 100644 tests/CheatEngine.Client.Repository.Tests/SourcePolicy/AotProbeCoverageTests.cs create mode 100644 tests/CheatEngine.Client.Tests/Packaging/TemplateInstantiationTests.cs diff --git a/CONTRIBUTING.md b/CONTRIBUTING.md index b8741bd..cd3dfb3 100644 --- a/CONTRIBUTING.md +++ b/CONTRIBUTING.md @@ -53,8 +53,13 @@ They include the template smoke tests: they install the packed `CheatEngine.Clie template home, run `dotnet new ceplugin --dry-run`, instantiate the template into a temporary directory outside the repository, restore it against the packed Client packages and nuget.org only, and build it in Release configuration.
