## 4. Merge vs 폐기 분석

### Merge 정당성 (★ 우세)
1. task-2658 chair_verified 산출물 (★ 회장 verbatim SPAWN_VISIBILITY_FALSE_NEGATIVE_PREVENTION_GUARD_IMPLEMENTED)
2. ANU 공통 도구로 main 반영 합리 (★ task-2657 사고 재발 차단 · false negative prevention)
3. 본 모듈은 **observer/judgment layer 한정** — PreToolUse runtime / Axis 1·2 runtime / dispatch.py / live settings.json / hooks / axis_3_canary_scale_aware_guard 전부 ZERO 변경 → **production runtime 영향 0**
4. 신규 디렉토리 `utils/anu_spawn_visibility_guard/` + `tests/anu_spawn_visibility_guard/` — 기존 파일 변경 0 → merge conflict 위험 LOW
5. regression 7/7 PASS (★ R1~R6 + R3-bonus)

### 폐기 정당성 (★ 부재)
- 회장 verbatim 폐기 지시 없음
- 회장 chair_verified 산출물 (★ chair_acceptance_basis_verbatim_12)

### 결론
**★ Merge 권장** (★ 본 task 범위 외 · 회장 결정 시 적용)

## 5. CI/Gemini 현황

- ★ 본 packet 작성 시점 직접 조회 0 (★ allowed_resources commands에 `gh` 미포함 + task md "실 처리 0" anchor)
- ★ 회장 결정 시 점검 절차:
  1. `gh pr checks 147` — CI status (★ pass/fail/pending 확인)
  2. `gh api repos/Jeon-Jonghyuk/dev_workspace/pulls/147/reviews` — Gemini 리뷰 존재 + High severity 미수정 0건 확인
  3. `gh pr view 147 --json mergeable,mergeStateStatus` — mergeable=MERGEABLE + mergeStateStatus=CLEAN 확인
- ★ task-2658 report `이슈 1`: Pyright LSP `utils.anu_spawn_visibility_guard` import 미해결 (★ false positive · py_compile 통과로 해소). PR Gemini 리뷰가 동일 false positive 제기 가능 → **dismiss 사유 사전 준비** 권장 (★ `[DISMISS] Pyright LSP false positive · worktree 디렉터리 미인덱스 사유 · py_compile + pytest 7/7 PASS evidence`)

## 6. 의존 Task 매핑

| task | 관계 | 상태 |
| --- | --- | --- |
| task-2657 | Axis 3 canary scale-aware guard (★ 본 guard 직접 사유 · false negative 사고 원천) | chair_verified IMPLEMENTED |
| task-2658 | SPAWN_VISIBILITY_FALSE_NEGATIVE_PREVENTION_GUARD source | chair_verified IMPLEMENTED |
| task-2659 | promotion branch task (★ PR #147 source branch label) | task md scope 외 (★ 별도 확인 필요) |
| task-2660 | (★ 본 packet Item 2 · SUPERSEDED by PR #148) | superseded |
| task-2661 | (★ PR #148 merged) | merged |

★ PR #147 merge가 진행되더라도 **Axis 3 canary observer chain RUNNING 자동선언 0** anchor 강제 — task-2658 marker `axis_3_canary_status_unchanged_anchor` 유지.

## 7. Recommended Action Sequence (★ 본 task 범위 외 · 회장 결정 위임)

1. 회장 verbatim PR #147 merge 결정 수신
2. `gh pr checks 147` + `gh api .../reviews` 사전 점검
3. Gemini High 미수정 0 확인 (★ 또는 dismiss 사유 박제 후 수정 0건 0 강제)
4. `gh pr merge 147 --squash --delete-branch` (★ auto-merge label 부착 0 anchor)
5. merge commit sha → result marker 박제 (★ task-2658 marker `anu_spawn_visibility_guard_canonical_promotion_merged` 후속)
6. **Axis 3 RUNNING 자동선언 강제 0** 재확인

## 8. forbidden_action_count

**0**. 실 PR merge / 폐기 / Gemini 리뷰 요청 — 전 0. 본 packet 작성만.
