root 정식 개발 workflow13개 및 root related 목록에서 이 결함 활성 source 없음. 기존 K04 owned-job/K05 replaced-session 큐는 closedr4(10-20)이며 이번 archived-worktree barrier DB 성능 회귀와 다른 완료 단위. 해당 옛flow 재기동/재close0. p320 filename/activeflow scoped조회에 새 ARCHIVE-RECLAIM 항목 없음 확인. 이번 queue/external_id 하나로 정식 생성·연결한다.
current integration owner=c9123a69-fbbd-4754-b789-7f643c9afa25 / SID d26b32b6-fed5-412b-9457-3803cfd69e86, PR368. 그 worker만 codex/production 최종ref 쓰기 owner다. root가 새결함 예정입력을 queued 전달했다(operation8e-replace1027-archive-barrier-bug-reservation-20261027). source 변경 경로를 구현 전에 정확하게 root에 알리고 overlap은 그 순서부터 조율한다. c912 기존 승인 source 통합·빌드는 독립 계속, 새결함 때문에 중복 통합자/빌드자 생성0.
초기 root source 관측: resource_cleanup.go의 createTaskResourceCleanupJob은 BeginTxx→recoveryclaim.EnsureTaskAvailableTx→managedDeletionBarrierTx→archive generation 재확인→INSERT ON CONFLICT(operation_id) DO NOTHING. managedDeletionBarrierTx는 SQLite UPDATE tasks SET id=id WHERE0으로 writer lock 확보 후 task_resource_cleanup_jobs에서 task_id/state5종/managed_delete JSON marker EXISTS를 읽는다. PostgreSQL은 task FOR UPDATE. 이 구조 관측은 원인 확정이 아니며 사본 실제 queryplan/row분포/시간으로 인과를 입증한다. 이 다중 호출 barrier의 correctness를 성능 때문에 삭제하지 않는다.
