Refactor Clean

Safely identify and remove dead code with test verification:

1. Run dead code analysis tools:

   • vulture: Find unused Python code (functions, classes, variables)
   • pyflakes: Detect unused imports and variables
   • ruff check --select F401: Find unused imports
   • pip-audit: Check for security vulnerabilities

2. Generate comprehensive report in .reports/dead-code-analysis.md

3. Categorize findings by severity:

   • SAFE: Test files, unused utilities, unused imports
   • CAUTION: API routes, models, fixtures
   • DANGER: Config files, main entry points, registry decorators

4. Propose safe deletions only

5. Before each deletion:

   • Run full test suite (pytest)
   • Verify tests pass
   • Apply change
   • Re-run tests
   • Rollback if tests fail

6. Show summary of cleaned items

Never delete code without running tests first!
