**Verdict**: PASS

## Findings

| # | Severity | Category | File:Line | Title |
|---|----------|----------|-----------|-------|
| - | - | - | - | No findings |

## Review Notes

- AC-1 is satisfied by the public exports in `src/shared/contracts/__init__.py` and the DTO models in `src/shared/contracts/models.py`.
- AC-2 is satisfied by Pydantic validation for missing required fields, raw frame retention, optimistic covariance reporting, and inconsistent anchor decisions.
- The implementation stays inside `shared/contracts` ownership and does not introduce component-specific algorithms.
- Raw frame payloads remain references only; the model rejects retained raw-frame payload flags.
