Summary

  • correct stale release annotations for immutable GitHub Action pins
  • enforce one release annotation per immutable action SHA across workflows and composite actions
  • add repository-wide checks for immutable references and release-shaped annotations

Closes #1543

Issue #1228 is intentionally not included: cross-repository reusable-workflow identity requires a separate reviewed trust exchange.

Verification

  • python -m pytest -q tests/test_action_pin_annotation_integrity.py tests/test_exact_artifact_sbom_attestation_contract.py (14 passed)
  • python -m compileall -q tests/test_action_pin_annotation_integrity.py
  • git diff --check
  • YAML parsing passed for all three modified workflows

Summary by CodeRabbit

  • 보안 및 안정성

    • 보안 검사와 아티팩트 업로드에 사용되는 GitHub Actions를 최신 검토 버전으로 업데이트했습니다.
    • 증거 아티팩트와 소스 커밋의 저장소 및 커밋 일치 검증 기준을 명확히 했습니다.
  • 검증

    • 외부 액션의 커밋 고정, 릴리스 주석 일관성, 주요 보안 액션의 승인된 버전 사용을 자동 검증합니다.
  • 문서

    • 액션 핀 주석 무결성 검증에 대한 변경 이력을 추가했습니다.

Explanation

[Issue #1543] 새 테스트는 immutable action의 주석 일관성, 외부 action의 SHA 고정, OSV sub-action의 단일 SHA를 검사합니다. security-scan.yml의 reporter 주석도 현재 OSV SHA로 수정되었습니다. 그러나 이 PR 변경 요약에는 요구된 APA 7 doctoringdocs/product-technical-gap-baseline.md의 현재 upstream 근거 갱신이 없습니다. 또한 actionlint와 완전한 central contract 테스트의 통과 결과를 확인할 수 없습니다.

현재 테스트는 SHA와 주석 형식·일관성만 검사합니다. 다음 매핑을 명시적으로 검증해야 합니다.
