"""post186_callback_finalize_dogfood_audit.py — PR#186 이후 callback/finalize 경로 격리 dogfood 하니스

목적:

  finish-task.sh G2(nullglob-safe dirty 면제) 가 canonical 이 non-main 브랜치에

  - 수동 .done 생성 0, real ANU spawn 0, production activation 0
  - ACTIVE=false

Doctrine:
  - canonical /home/jay/workspace 는 읽기 전용 참조만
  - 모든 git 작업은 tempfile.mkdtemp() 격리 디렉토리 내부
  - 임시 디렉토리는 finally 블록에서 shutil.rmtree 정리
