# v1.59 Milestone Audit

Status: passed

## Scope Closed

- Phase `109`: runtime compat surface prune contract
- Phase `110`: prune command and service path
- Phase `111`: closure and regression audit

## Production Outcome

`v1.59` now exposes a reviewable compatibility-surface pruning flow through:

- `research/knowledge-hub/knowledge_hub/compat_surface_cleanup_support.py`
- `research/knowledge-hub/knowledge_hub/aitp_service.py`
- `research/knowledge-hub/knowledge_hub/aitp_cli.py`
- `research/knowledge-hub/tests/test_runtime_compat_surface_cleanup.py`

## Verification Evidence

- compat-surface cleanup slice:
  - `python -m pytest research/knowledge-hub/tests/test_runtime_compat_surface_cleanup.py research/knowledge-hub/tests/test_aitp_cli_e2e.py::AITPCLIE2ETests::test_prune_compat_surfaces_command_uses_real_service_path -q`
  - result: `3 passed`
- CLI unit slice:
  - `python -m pytest research/knowledge-hub/tests/test_aitp_cli.py -q`
  - result: `37 passed`
- full knowledge-hub suite:
  - `python -m pytest research/knowledge-hub/tests -q`
  - result: `340 passed, 10 subtests passed`
