# task-2550+1 plan — .worktrees auto-cleanup policy + worktree_cleanup.py clean replacement

**status**: in-progress
**level**: Lv.4 (control-plane, security/correctness)
**team**: dev5 (마르둑)
**replacement_of**: task-2550 / PR #100 (IMPLEMENTATION_SPEC_INCOMPLETE)
**original_head**: 4067d8c43833155f5ea626255645549602a23bbb

## 목표

PR #100 Gemini fresh review (head 4067d8c4) 6 unresolved findings (HIGH 1 + medium 4 unique + duplicate 1) 의 corrected clean replacement.

- HIGH: `task_id in headRefName` substring 오탐 차단 (task-25 vs task-2550 boundary 본질 결함)
- medium #1: `hash()` 비결정론 → `hashlib.sha256` 결정론
- medium #2: `pgrep -f` argv-only → `lsof +D` AND 게이트 보완
- medium #3: `r.all_safe` dry-run 가시성 상실 → `is_safe_ignoring_apply` helper
- medium #4 (duplicate dedupe): MED-3 와 통합

본 task 는 같은-PR push doctrine 위반 회피 위해 fresh PR 으로 진행. PR #100 보존 (failed original evidence).

## 18단계 실행 흐름

**Phase A — Bootstrap (3단계)**:
1. cokacdir 시작 + dev5 worktree 환경 확인
2. `.worktrees/task-2550plus1-dev5` 생성 (origin/main bf59e7d2 기준)
3. PR #100 head 4067d8c4 baseline 4 file 추출 (worktree_cleanup, post_merge_smoke_runner + 2 tests)

**Phase B — Implementation (4단계)**:
4. Gemini 6 unresolved triage → `gemini_triage_decision.json`
5. HIGH `_matches_task_id_strict` 두 단 게이트 (regex 경계 + extracted 동등)
6. medium 4 fix (sha256 hash / lsof CWD / cleanup_candidates ignoring apply)
7. boundary test (task-25/2500/250/2550/2550+1) + concurrency test (PYTHONHASHSEED 결정론)

**Phase C — Verification (5단계)**:
8. pytest 전체 회귀 (anu_v2 432 + 신규 31) PASS
9. pyright 0 errors
10. effective diff == 11 expected_files
11. forbidden path 0
12. PR 생성 (BOT identity, base=main)

**Phase D — Finalize (6단계)**:
13. Gemini fresh review (capability runner 자동 호출 — FIRST_MISSING/STALE 시 OWNER_GEMINI_TRIGGER_TOKEN)
14. unresolved 0 어셀션
15. CI 11/11 SUCCESS
16. mergeStateStatus CLEAN
17. BOT squash merge (admin override 0)
18. smoke/reconcile evidence + lifecycle markers (done.acked/merge-done) + 보고서 + **PR #100 original head 4067d8c4 unchanged 어셀션**
