# v1.57 Milestone Audit

Status: passed

## Scope Closed

- Phase `103`: phase6 structural test split
- Phase `104`: phase6 behavioral test isolation
- Phase `105`: closure and regression audit

## Production Outcome

`v1.57` now exposes a reviewable structural-versus-behavioral phase6 split
through:

- `research/knowledge-hub/tests/test_phase6_schema_contracts.py`
- `research/knowledge-hub/tests/test_phase6_protocols.py`

## Verification Evidence

- phase6 split slice:
  - `python -m pytest research/knowledge-hub/tests/test_phase6_schema_contracts.py research/knowledge-hub/tests/test_phase6_protocols.py -q`
  - result: `5 passed`
- full knowledge-hub suite:
  - `python -m pytest research/knowledge-hub/tests -q`
  - result: `337 passed, 10 subtests passed`
