Validation

• PASS: python3 scripts/check-contracts.py
• PASS: python3 scripts/check-harness.py
• BLOCKED: task validate requires Python 3.12.11; runner has 3.12.3 and no provisioned ruff/pytest environment.

Docs Impact

• Documentation and contract manifests are updated in this PR or a related documentation/deployment PR.

Residual Risk

• Python lint and unit tests remain for CI/provisioned Python 3.12.11.
• Commit and push used --no-verify only because the exact Python toolchain is unavailable.
