## Rules

- Never claim "should work" without evidence
- Never claim success without exit code 0
- Never claim a bug is fixed without reproduction failure
- Always capture and report exit codes
- Always run the full test suite, not just targeted tests
- Use timeout guards (`timeout 60s`) to prevent hanging

## When to Use

- Before completing any BUILD workflow step
- Before claiming a DEBUG fix is verified
- Before approving a REVIEW result
- Before marking any task as done

## Agents Used

- `integration-verifier` (primary consumer)
- `component-builder` (TDD evidence)
- `bug-investigator` (fix evidence)
