# v1.62 Milestone Audit

Status: passed

## Scope Closed

- Phase `118`: scratchpad contract
- Phase `119`: scratchpad runtime and CLI surface
- Phase `120`: closure and regression audit

## Production Outcome

`v1.62` now exposes a reviewable scratchpad surface through:

- `research/knowledge-hub/knowledge_hub/scratchpad_support.py`
- `research/knowledge-hub/knowledge_hub/topic_shell_support.py`
- `research/knowledge-hub/knowledge_hub/runtime_bundle_support.py`
- `research/knowledge-hub/knowledge_hub/aitp_service.py`
- `research/knowledge-hub/knowledge_hub/aitp_cli.py`
- `research/knowledge-hub/tests/test_scratchpad_support.py`

## Verification Evidence

- scratchpad targeted slice:
  - `python -m pytest research/knowledge-hub/tests/test_runtime_profiles_and_projections.py research/knowledge-hub/tests/test_aitp_cli.py research/knowledge-hub/tests/test_aitp_cli_e2e.py research/knowledge-hub/tests/test_aitp_service.py research/knowledge-hub/tests/test_schema_contracts.py research/knowledge-hub/tests/test_scratchpad_support.py -q`
  - result: `209 passed`
- maintainability-budget gate:
  - `python -m pytest research/knowledge-hub/tests/test_maintainability_budgets.py -q`
  - result: `2 passed`
- full knowledge-hub suite:
  - `python -m pytest research/knowledge-hub/tests -q`
  - result: `359 passed, 10 subtests passed`
