Check AI slop: excessive comments, over-abstraction, generic names (data/result/item/temp), unnecessary null checks on non-nullable types.

   Start `docker compose up` from clean state. Execute EVERY QA scenario from EVERY task — follow exact steps, capture evidence. Test cross-task integration: login → pick club → create task → assign → transition through states → switch club → verify isolation → create shift → sign up → verify capacity. Test edge cases: invalid JWT, expired token, cross-tenant header spoof, concurrent sign-up. Save to `.sisyphus/evidence/final-qa/`.
