# v1.49 Milestone Audit

Status: passed

## Scope Closed

- Phase `78`: quick exploration entrypoint and lightweight session
- Phase `79`: artifact footprint baseline and slim runtime path
- Phase `80`: promote exploration into full topic work
- Phase `81`: docs, acceptance, and regression closure

## Production Outcome

`v1.49` now exposes a low-bureaucracy exploration chain through durable
runtime artifacts:

- `runtime/explorations/<exploration_id>/explore_session.json|md`
- `runtime/explorations/<exploration_id>/promotion_request.json|md`

Those surfaces are reachable through production `aitp explore` and
`aitp promote-exploration`.

## Verification Evidence

- milestone-close exploration slice:
  - `python -m pytest research/knowledge-hub/tests/test_aitp_service.py research/knowledge-hub/tests/test_aitp_cli.py research/knowledge-hub/tests/test_quick_exploration_contracts.py -q`
  - result: `161 passed`
- isolated acceptance:
  - `python research/knowledge-hub/runtime/scripts/run_quick_exploration_acceptance.py --json`
  - result: passed
- maintainability watch budget:
  - `python -m pytest research/knowledge-hub/tests/test_maintainability_budgets.py::MaintainabilityBudgetTests::test_watchlisted_files_stay_within_declared_budgets -q`
  - result: `1 passed`
- full knowledge-hub suite:
  - `python -m pytest research/knowledge-hub/tests -q`
  - result: `323 passed, 10 subtests passed`

## Residual Risk

- no next milestone has been selected yet
- future work should not route quick exploration back through hidden full topic bootstrap
