Purpose

Read-only hygiene checker. Verifies gitignore patterns, flags scratch artifacts, asserts SC-007 line-count delta.

What it produces / drives

Writes a hygiene report under state/hygiene_<run-id>.yaml; emits review-style record on violation.

Dependencies

Acceptance criteria

• Catches files matching common scratch patterns (*.tmp, *.bak, scratch.py)
• Catches files that should be in .gitignore but aren't
• Asserts SC-007: project line-count delta within budget

Manual test plan

1. Add a scratch.py file to a project
2. Run repository_hygiene
3. Verify the report flags scratch.py
