## Watchlist

No near-threshold files found.

## Early Watchlist

| File | Lines | Kind | Recommended next split |
| --- | ---: | --- | --- |
| `tests/verify_yao_cli.py` | `696` | `test` | Break broad integration assertions into focused verifier helpers when the next behavior change lands. |
| `tests/verify_world_class_evidence_intake.py` | `628` | `test` | Break broad integration assertions into focused verifier helpers when the next behavior change lands. |

## Release Rule

- `block` hotspots should be split before governed release.
- `warn` hotspots can ship only when Review Studio keeps them visible and a reviewer accepts the modularization plan.
- Do not split a file only for line count; split when a stable responsibility boundary is clear.
