I read this as an offline verification pass for Task23 activation/cutover behavior - inspect the diff/artifacts, run the focused checks and disposable E2E, and report either confirmed or one exact blocker.


I read this as an offline verification pass with a hard static-quality gate, and the exact blocker is: changed-file Ruff/ty are not clean.

- `ruff format --check` on the modified `checkin_cli` files fails, with 24 files reported as needing reformatting.
- `ty check` on the same changed-file set fails with 255 diagnostics, first at `checkin_cli/customer_coaching.py:424` (`policy_digest` unresolved).

Verified green:
- `pytest -q tests/test_customer_admin.py tests/test_nutrition_onboarding.py tests/test_nutrition_onboarding_cli.py tests/test_nutrition_readiness.py tests/test_wizard_domain.py` → 185 passed
- `pytest -q tests/test_adaptive_nutrition.py tests/test_customer_coaching_domain.py tests/test_customer_reporting.py tests/test_coaching_grounding.py tests/test_nutrition_onboarding_admin.py` → 187 passed
- `python -m compileall -q checkin_cli tests` passed
- `python -m build --wheel` passed

Temp build artifacts were cleaned.
