Summary

Implemented multi-platform testing across Linux, macOS, and Windows to ensure cross-platform compatibility.

Changes

Test Matrix Expansion

• Added OS matrix to test job: ubuntu-latest, macos-latest, windows-latest
• Combined with existing Rust version matrix (MSRV + stable)
• Results in 6 test combinations: 2 Rust versions × 3 operating systems

Cache Optimization

• Updated cache keys to include OS: test-${{ matrix.rust }}-${{ matrix.os }}
• Prevents cache conflicts between different platforms
• Each platform maintains its own cargo cache

Platform-Specific Operations

• Restricted README operations to ubuntu-latest only
• Prevents git conflicts from multiple platforms attempting README updates
• Includes: lockfile verification, README generation, drift detection, autocommit

Artifact Management

• Updated test artifact names to include OS
• Format: test-results-${{ matrix.rust }}-${{ matrix.os }}.json
• Test summary shows all platform artifacts with 30-day retention

Benefits

• Cross-Platform Assurance: Automatic verification on Linux, macOS, and Windows
• Early Bug Detection: Platform-specific issues caught before release
• Enterprise Readiness: Demonstrates compatibility across major operating systems
• Isolated Caching: No cache contamination between platforms

Test Plan

• Workflow YAML validated
• Local tests pass on Linux (157 tests)
• Cargo fmt and clippy pass
• README regenerated successfully
• Changes committed and pushed

Technical Details

Matrix Strategy:

strategy:
  fail-fast: false
  matrix:
    rust:
      - ${{ needs.msrv.outputs.version }}
      - stable
    os:
      - ubuntu-latest
      - macos-latest
      - windows-latest

Platform-Specific Conditions Example:

if: matrix.rust == needs.msrv.outputs.version && matrix.os == 'ubuntu-latest'

Next Steps

After merge:

• Monitor first CI run across all platforms
• Address any platform-specific failures if they arise
• Proceed with Phase 3: Add supply chain security (SBOM + Sigstore) #187 (Supply Chain Security)

Closes #186

	- name: Generate test report (JSON format)
	if: always()
	continue-on-error: true

Use bash shell for JSON test report generation

The test job now runs on Windows, but the "Generate test report (JSON format)" step still relies on bash syntax (|| true and the backslash line continuation) without declaring shell: bash. On Windows runners GitHub defaults to PowerShell, so the script fails before producing test-results-*.json. The subsequent artifact upload step then errors because the file is missing, causing the whole Windows matrix job—and any downstream jobs that depend on test—to fail. Add shell: bash to this step or rewrite the command for PowerShell so the new OS matrix can complete.
