"""ANU 직접 polling violation guard — task-2643 Track D.

PR #145 task-2642 박제 승격 (회장 verbatim · task md 7 acceptance):

1. bzaona6au 사건 명령 재현 → hook 가 반드시 deny
2. deny reason = "ANU_DIRECT_CI_POLLING_FORBIDDEN" 고정
3. deny payload 에 allowed_alternative="delegated_watcher_contract" 포함
4. deny payload 에 next_steps 안내 (watcher contract 가이드 포함)
5. fixture PROVENANCE 가 incident_ts_kst + 정책 feedback md 경로 명시
6. fixture evidence 가 정책 출처 + 이벤트 박제 경로 reference 포함
7. cross-link Track C fixture (`pr_145_bzaona6au_violation_replay`) 존재 + 동일 사건 박제

본 task-2643 의 PR scope 는 origin/main 에서 분기되므로 PR #145 산출물에 직접
경로 의존성을 두지 않는다. 대신 fixture 내부 박제 (evidence/PROVENANCE) 로 사건을
정합한다 (회장 verbatim · PR #145 혼합 0).
