🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Correct the recovery instruction.
RequireMemory() tells callers to pass the service to Read/Write. Those primitive methods do not accept an IMemoryClient. Tell callers to bind the service with Using(memory) or a bound At factory.
Proposed fix
return _memory ?? throw new InvalidOperationException(
"This memory builder has no bound target-memory service. Use Memory.At(memory, address), " +
- "memory.At(address), or pass the service to Read/Write.");
+ "memory.At(address), or Using(memory) before a terminal operation.");📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Add the consumer-facing Fluent layer over the public contracts. The AOB builders normalize patterns and scan options, retain immutable state, provide module/range/protection/alignment filtering, and require bounded terminals (first, single, or explicit materialization limit). Memory builders bind an address to typed read and write operations without retaining Cheat Engine handles. The layer remains SDK-free and therefore cannot bypass activation, dispatch, policy, or ownership controls established by Core. Focused tests preserve request propagation and failure semantics. Validation: - dotnet build libs/CheatEngine.Client.Fluent/CheatEngine.Client.Fluent.csproj --configuration Release --no-restore --warnaserror - dotnet test --project tests/CheatEngine.Client.Fluent.Tests/CheatEngine.Client.Fluent.Tests.csproj --configuration Release --no-build --no-restore --fail-skips on
Exercise the AOB and memory terminal builders across successful forwarding, host failures, defaults, and invalid argument paths. The added cases bring the Fluent project to full local line and branch coverage for the Sonar quality gate.
Correct the unbound builder error guidance so it names the three valid binding paths instead of suggesting unsupported Read/Write overloads. Add a focused regression assertion and complete the relevant public XML documentation for null and binding failures.
Add the activation-scoped composition and plugin hosting layers. CheatEngineClientBuilder configures explicit codecs, modules, options, logging, trusted table roots, and unsafe-Lua policy. AddCheatEngineClient wires the Core dependencies into one per-activation client. CheatEngineClientPlugin builds a validated scoped provider on enable, enables modules deterministically, rolls back failures, drains owned Cheat Engine resources while the SDK context remains valid, and disposes services on disable. The aggregate CheatEngine.Client package now re-exports Fluent and Hosting as the consumer entry point. Tests cover options, codec registration, dependency graph composition, module order, activation cleanup, and public SDK-handle boundaries. Validation: - dotnet build libs/CheatEngine.Client.Extensions.DependencyInjection/CheatEngine.Client.Extensions.DependencyInjection.csproj --configuration Release --no-restore --warnaserror - dotnet build libs/CheatEngine.Client.Hosting/CheatEngine.Client.Hosting.csproj --configuration Release --no-restore --warnaserror - dotnet test --project tests/CheatEngine.Client.Extensions.DependencyInjection.Tests/CheatEngine.Client.Extensions.DependencyInjection.Tests.csproj --configuration Release --no-build --no-restore --fail-skips on - dotnet test --project tests/CheatEngine.Client.Hosting.Tests/CheatEngine.Client.Hosting.Tests.csproj --configuration Release --no-build --no-restore --fail-skips on - dotnet test --project tests/CheatEngine.Client.Tests/CheatEngine.Client.Tests.csproj --configuration Release --no-build --no-restore --fail-skips on
Make the nullable allowed-root configuration truthful and keep the service factory defensive after generated option validation. Restrict the abstract plugin constructor to derived plugins and replace the throwing Client property with an explicit lifecycle-checked method.

Resolve the PR #4 DI and Hosting review findings without widening the stacked-branch scope.\n\nRemove unconsumed scan-limit settings and prevent configuration binding from activating unsafe Lua. The explicit builder opt-in now establishes the unsafe facade and Core policy together. Register lifecycle modules in the activation scope so they can consume scoped application services, and classify malformed table-root paths as validation failures.\n\nAdd stable Sonar project identifiers for the DI and Hosting assemblies, clarify lifecycle cleanup documentation, update the shipped API baseline and package guidance, and cover the configuration, scoped-module, malformed-path, and hosting-binding regressions.\n\nValidation:\n- dotnet restore CheatEngine.Client.slnx --locked-mode\n- dotnet build CheatEngine.Client.slnx --configuration Release --no-restore --warnaserror\n- DI tests: 22 passed, 0 failed, 0 skipped\n- Hosting tests: 8 passed, 0 failed, 0 skipped\n- git diff --check
Complete the release-facing repository shape after the modular client layers are in place. The solution now replaces the legacy Binding project with Core, publishes the template package and a Native AOT compatibility probe, adds package/template smoke scripts, and updates CI into reusable main and pull-request workflows. The canonical ceplugin template demonstrates explicit JSON configuration, DI modules, safe Lua module registration, direct SDK reference requirements, and managed-plugin deployment. The root documentation and ADR set now describe the package graph, activation lifecycle, capability gates, delivery policy, and local authorized-process boundary. Validation: - dotnet build CheatEngine.Client.slnx --configuration Release --no-restore --warnaserror - dotnet test --solution CheatEngine.Client.slnx --configuration Release --no-build --no-restore --report-trx --results-directory artifacts/test-results --fail-skips on - dotnet pack CheatEngine.Client.slnx --configuration Release --no-build --no-restore --output artifacts/packages - eng/Invoke-PackageSmoke.ps1 -PackageSource artifacts/packages - eng/Invoke-TemplateSmoke.ps1 -PackageSource artifacts/packages - dotnet publish tests/CheatEngine.Client.AotProbe/CheatEngine.Client.AotProbe.csproj --configuration Release --runtime win-x64 --no-restore --output artifacts/aot-probe - artifacts/aot-probe/CheatEngine.Client.AotProbe.exe
Run the scanner around a locked Release build and native-MTP Cobertura test execution, then publish the reports as a retained workflow artifact. Keep the CECLIENT001 negative package smoke check strict while clearing its expected native-command exit status only after the diagnostic is verified.
Make missing TRX output a hard validation failure and move Sonar's JDK setup to the immutable Node 24-compatible setup-java v6.0.1 revision. Let generated-plugin Lua lease disposal reach the activation lifecycle for aggregation, document the generated callbacks and exports, correct the Native AOT publish invocation, and restore the façade package guidance for the required direct SDK reference.

Context
This stacked PR adds the SDK-free Fluent consumption layer after the public contracts (#1) and Core runtime (#2).
Why this exists
Plugin code should express intent directly without constructing mutable SDK options, retaining handles, or duplicating bounded-result checks. Fluent builders make the high-level Client ergonomics explicit while Core remains the only layer that talks to Cheat Engine.
What changed
ICheatEngineClientandIPatternScanner.FirstOrNone,RequireSingle, andTake.Design constraints
The Fluent project references only Abstractions. Builders are immutable value types and never capture SDK objects, Lua state, resource ownership, tasks, or threads.
