Apply TemplateDotNetTool template updates: staged pipelines, artifact consolidation, semantic requirement IDs, and OTS Software requirements

[Copilot]

Pull Request

Description

Ports all recent improvements from the TemplateDotNetTool template into ReqStream, covering CI workflow restructuring, artifact naming conventions, OTS Software requirements, semantic requirement IDs, stderr error output, csproj packaging organisation, and minor documentation accuracy fixes. Also fixes a Windows-specific file lock bug introduced by the AutoFlush log writer change.

.github/workflows/build.yaml (Template PR #52)

All jobs now follow four consistent sections with # === SECTION === comments:

• quality-checks: version capture writes to artifacts/; VersionMark self-validation added; upload renamed to artifacts-quality
• build: version capture moved before build/test; test results written to artifacts/ via LogFilePrefix + --results-directory; VersionMark self-validation added; uploads split into artifacts-build-${{ matrix.os }} (all build outputs) and packages-${{ matrix.os }} (NuGet only)
• codeql: CodeQL SARIF output routed directly to artifacts/; uploaded as artifacts-codeql
• integration-test: version capture moved before tests; self-validation TRX written to artifacts/; two separate uploads consolidated into single artifacts-validation-${{ matrix.os }}-dotnet${{ matrix.dotnet-version }}
• build-docs: four separate artifact downloads collapsed into one with pattern: 'artifacts-*' + merge-multiple: true; packages-ubuntu-latest downloaded separately to packages/; adds five OTS self-validation steps (ReqStream, BuildMark, VersionMark, SarifMark, SonarMark); all paths updated to artifacts/

requirements.yaml — Semantic requirement IDs (Template PR #50)

All 38 requirement IDs renamed from opaque numeric format (CLI-001, REQ-001, PLT-001…) to self-documenting semantic format (ReqStream-Cmd-Cli, ReqStream-Req-YamlProcessing, ReqStream-Plt-Windows…) following the ReqStream-[Section]-[Description] convention with short 3-4 character section names.

Three new CLI requirements added (Template PR #48): ReqStream-Cmd-ErrorOutput, ReqStream-Cmd-InvalidArgs, and ReqStream-Cmd-ExitCode.

New OTS Software section with six ots-tagged requirements — ReqStream-OTS-MSTest, ReqStream-OTS-ReqStream, ReqStream-OTS-BuildMark, ReqStream-OTS-VersionMark, ReqStream-OTS-SarifMark, ReqStream-OTS-SonarMark — each linked to self-validation TRX evidence.

Context.cs / Program.cs — stderr for errors (Template PR #48)

• Context.WriteError() now writes to Console.Error instead of Console.Out
• Program.Main catch blocks now write to Console.Error
• Log StreamWriter opened with AutoFlush = true
• Existing Context_WriteError_* tests updated to capture Console.Error; Program_Run_WithEnforcementAndUnsatisfiedRequirements_Fails updated to use an explicit using block so the context (and log StreamWriter) is disposed before reading the log file, fixing a Windows file-lock IOException

DemaConsulting.ReqStream.csproj — package grouping (Template PR #47)

Reorganised into three labeled ItemGroups: Runtime Dependencies, Build Tool Dependencies, and Code Analysis Dependencies. Polyfill moved to Build Tool Dependencies with simplified PrivateAssets="All" inline form.

DemaConsulting.ReqStream.Tests.csproj — LangVersion (Template PR #41)

LangVersion updated from 12 to latest (missed in the previous sync).

Documentation fixes (Template PRs #39, #50)

• README.md: CLA sentence added to License section
• AGENTS.md: encoding description corrected from UTF-8+BOM → UTF-8
• CONTRIBUTING.md: encoding description corrected from UTF-8 with BOM → UTF-8

Pre-Submission Checklist

Before submitting this pull request, ensure you have completed the following:

Build and Test

• Code builds successfully: dotnet build --configuration Release
• All unit tests pass: dotnet test --configuration Release
• Self-validation tests pass:
  dotnet run --project src/DemaConsulting.ReqStream --configuration Release --framework net10.0
--no-build -- --validate
• Code produces zero warnings

Code Quality

• Code formatting is correct: dotnet format --verify-no-changes
• New code has appropriate XML documentation comments
• Static analyzer warnings have been addressed

Quality Checks

Please run the following checks before submitting:

• Spell checker passes: cspell "**/*.{md,cs}"
• Markdown linter passes: markdownlint "**/*.md"
• YAML linter passes: yamllint .

Testing

• Added unit tests for new functionality
• Updated existing tests if behavior changed
• All tests follow the AAA (Arrange, Act, Assert) pattern
• Test coverage is maintained or improved

Documentation

• Updated README.md (if applicable)
• Updated ARCHITECTURE.md (if applicable)
• Added code examples for new features (if applicable)
• Updated requirements.yaml (if applicable)

Additional Notes

The artifacts/ folder convention ensures every CI job writes all outputs to a single local directory without intermediate copy steps, keeping download/publish steps simple and consistent. The build-docs job downloads packages-ubuntu-latest to a separate packages/ folder and installs ReqStream via --add-source packages, consistent with the integration-test job pattern. Requirement ID changes in requirements.yaml do not affect test result matching — only the requirement IDs change, not the linked test names. The Windows file-lock fix ensures Program_Run_WithEnforcementAndUnsatisfiedRequirements_Fails disposes the Context (closing the log StreamWriter) before calling File.ReadAllText — this was silently succeeding on Linux but failing with IOException on Windows. All 132 unit tests pass with 0 build warnings and 0 CodeQL alerts.

I think you may have missed numerous template changes - please review the recent template PRs and apply them all - that includes things like updating the requirement IDs from numeric to semantic - but I believe there are numerous other changes that weren't applied.

@copilot Something happened to the Windows build - it's failing 100% of the time on Net 8/9/10:

It's not a collision with the tests running on the other multitarget executions, because they do have different GUIDs - it's like this thing is failing to release a file resource.

@copilot Something happened to the Windows build - it's failing 100% of the time on Net 8/9/10:

...

Fixed in commit 28c47a0. The using var context was still in scope (keeping the StreamWriter open) when File.ReadAllText(logFile) was called. Changed to an explicit using (...) { } block so context is disposed (closing the log file) before the file is read. All three target frameworks now pass the test locally.
