83-105: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winAdd the null-epoch survival case to this test.
DisposeTargetSelectionmust not release resources tracked throughTrack(resource), which store a nullTargetSelectionEpoch. That separation between the activation epoch and the target-selection epoch is the core invariant of the registry. This test mixes only two long epochs, so a regression that treated a null epoch as matching would still pass.💚 Proposed addition

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Release the reserved symbol name only when the lease did not release it.
SymbolRegistrationLease.Dispose calls releaseName(Name), which is ReleaseSymbolName. When created.Dispose() succeeds in this catch block, line 270 releases the same name a second time. A concurrent TryRegisterSymbol for the same name can reserve the name between the two releases. Line 270 then removes that new reservation, so two live leases can own one Cheat Engine symbol name, and the first unregister removes the other lease's symbol.
Keep the fallback release for the case where Dispose throws before it releases the name. Make it conditional on the lease state.
🐛 Proposed fix
catch (Exception exception)
{
try
{
created.Dispose();
}
catch
{
- // The original lifecycle failure is the meaningful result. The registration name was still released below.
+ // The original lifecycle failure is the meaningful result. The fallback release below runs because
+ // the lease did not reach its own release step.
}
- ReleaseSymbolName(registration.Name);
+ if (!created.IsReleased)
+ {
+ ReleaseSymbolName(registration.Name);
+ }

Distinguish a root from a failed parent read. GetNextParentChainStep maps every TryGetParent failure to ParentChainStep.Root. CheatEngine.SDK returns false both for a root record whose Parent is nil and for a protected property-access error. A failed read can therefore terminate validation successfully before the chain reaches the child. If the subsequent assignment succeeds, it can create a parent cycle.
Change GetNextParentChainStep to consume a parent-read result that distinguishes nil from a host error. Map nil to ParentChainStep.Root and the host error to ParentChainStep.HostRejected.

Correct the InvalidRelationship failure message.
TableParentRelationshipGuard.Validate returns InvalidRelationship for three cases: the candidate parent equals the child, the candidate chain already contains a cycle, and the chain exceeds the hop bound. MutationFailure reports all three as "A memory record cannot be its own parent." For an indirect cycle the message is wrong and misleads the caller.
Use a message that covers every rejected relationship.
🐛 Proposed message fix
TableRecordMutationStatus.InvalidRelationship => new CheatEngineFailure(
CheatEngineFailureKind.OperationRejected, operation,
- "A memory record cannot be its own parent."),
+ "The requested parent relationship is invalid because it would create a cycle."),📝 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.

Update the InvalidRelationship case in MutationFailure to use a message covering
self-parenting, indirect cycles, and exceeded relationship depth, rather than
only stating that a record cannot be its own parent. Preserve the existing
failure kind and operation values.

Correct the Fluent arrow direction.
Every other edge in this diagram points from the dependent package to the package it references, with the arrowhead on the referenced package. Line 27 uses Abstractions ← Core because Core references Abstractions. Line 31 reverses that for Fluent and therefore states that Abstractions depends on Fluent.

Implement the internal Core layer that adapts CheatEngine.SDK behind the public Abstractions contracts. The implementation introduces activation and target-selection lifetimes, synchronized main-thread dispatch, classified failures, protected Lua/module leases, typed memory codecs and pointer chains, process/runtime inspection, bounded AOB materialization, table record operations, and a capability-gated value-scan state machine. SDK ownership and Lua handles remain internal. The Core resource registry disposes forgotten resources in LIFO order during activation cleanup, while the dispatcher preserves callback exceptions and epoch expiration semantics. Focused tests cover lifecycle cleanup, memory, processes, AOB, Lua, symbols, tables, and unavailable value scanning. Validation: - dotnet build libs/CheatEngine.Client.Core/CheatEngine.Client.Core.csproj --configuration Release --no-restore --warnaserror - dotnet test --project tests/CheatEngine.Client.Core.Tests/CheatEngine.Client.Core.Tests.csproj --configuration Release --no-build --no-restore --fail-skips on
Construct runtime and table snapshots through the cohesive foundation contracts, reducing public constructor complexity without leaking SDK ownership. Keep Core table mutation tests aligned with the handle-free snapshot boundary.
Resolve the actionable CodeRabbit findings in the activation-bound Core layer without expanding its public surface.\n\nDisambiguate a root MemoryRecord from a protected Lua parent-read failure before hierarchy validation, and end that raw Lua operation before the ID lookup opens another SDK operation. Harden symbol-name reservation cleanup against a successful lease disposal releasing the same name twice, and make cleanup-scope entry atomic with overflow rollback.\n\nClarify rejected parent-relationship diagnostics, cover target-independent resource survival, correct the package graph documentation, and add focused table/registry regressions. Align LuaClient with the simplified TResult-inferred ILua contract while retaining internal forwarding overloads until the stacked Foundation update is synchronized.\n\nValidation:\n- dotnet build tests/CheatEngine.Client.Core.Tests/CheatEngine.Client.Core.Tests.csproj --configuration Release --no-restore --warnaserror\n- dotnet test --project tests/CheatEngine.Client.Core.Tests/CheatEngine.Client.Core.Tests.csproj --configuration Release --no-build --no-restore --fail-skips on --report-trx --results-directory artifacts/test-results/pr2-core\n- 80 passed, 0 failed, 0 skipped
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.

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 implements
CheatEngine.Client.Coreon top of the public-contract foundation from #1.Why this exists
The public API must remain fluent and handle-free while Cheat Engine calls still require SDK/Lua coordination, thread affinity, activation ownership, and deterministic cleanup. This PR creates that internal boundary.
What changed
