 - **PASSED:** `git diff --check`.
 - **PASSED:** `graphify update .` rebuilt the local AST graph without API/model use. It reported missing optional PDF/SQL parsers and files without extracted symbols; those are graph coverage limits, not application test failures. Generated `graphify-out/` remains local and untracked, as at the source worktree.

+Durable machine-readable red/final result names, outcomes, counts and timestamps: [verification.json](evidence/rules-freshness/verification.json). Exact native red, development-green and final-regression TRX files are preserved as `.trx.gz` files alongside it. [native-receipts.json](evidence/rules-freshness/native-receipts.json) records raw/compressed SHA256 hashes and byte lengths; gzip decompression reproduces the original receipts without text transformations. The seven-test development-green run overlaps the final regression run.
 
 Commands use the installed `C:\Users\Connor\.dotnet\dotnet.exe` SDK; the runtime-only Program Files executable cannot execute SDK commands. Test command: `dotnet test JobTrackerApi.Tests/JobTrackerApi.Tests.csproj --no-restore --filter "FullyQualifiedName~RuleSettingsFreshnessTests|FullyQualifiedName~JobQueryParityTests|FullyQualifiedName~JobApplicationsWorkflowSignalsTests|FullyQualifiedName~RulesEngineProspectTests|FullyQualifiedName~ConcurrentInitializationTests"`.
