- Around line 757-760: Update the copied_artifacts fixture in
tests/test_contract_artifacts.py to include README.md when assembling test
fixtures, so validate_release_metadata can load it and exercise the intended
README content validation.
- Around line 736-740: Update validate_release_metadata to require the exact
v0.4.0 specification commit hash 310407af3a9867065f76703f3b8ba4a1324daf42, using
a dedicated expected-commit constant alongside the existing release metadata
checks. Add a test covering rejection of a mismatched commit value while
preserving acceptance of the exact hash.
