+
+## 1. 개요 및 검토 배경 (Executive Summary)
+
+본 보고서는 Issue #3('[Bug] herdr 데몬 프로세스 분리(setsid) 누락으로 인한 세션 리셋 및 UUID 미할당 세션 resume 데드락 문제') 해결을 위해 수행된 코드 변경 사항(`c49ee3b`, `7e15081`)에 대해, **SemVer 2.0.0(유의적 버전 2.0.0)** 명세 및 본 프로젝트의 릴리스 관리 원칙에 입각하여 **버전 업데이트의 필요성 여부**, **적정 목표 버전 번호**, 그리고 **3-Way Version Lockstep 적용 터치포인트**를 종합 검토한 결과를 제시합니다.
+
+### 📌 핵심 결론 요약
+1. **버전 업데이트 필요성**: **필수 (REQUIRED)**  
+   - 프레임워크 런타임 진실 공급원인 `.agents/skills/lib.sh` 및 복원 스킬의 핵심 라이프사이클 스크립트(`.agents/skills/multi-agent-mux-resume/scripts/`)에 실제 런타임 버그 수정이 반영되었으며, 신규 회귀 테스트(`test_h26`, `test_t14`, `test_t15`, `test_t16`)가 추가되었으므로 릴리스 패키징 및 버전 추적이 반드시 수행되어야 합니다.
+2. **적정 목표 버전 번호**: **`v4.1.3` (PATCH Release)**  
+   - 공개 API의 호환되지 않는 변경(Breaking Changes) 없음 $\rightarrow$ MAJOR(`v5.0.0`) 배제
+   - 새로운 기능 서브시스템이나 신규 에이전트 어댑터 추가 없음 $\rightarrow$ MINOR(`v4.2.0`) 배제
+   - 기존 결함에 대한 100% 하위 호환 내부 버그 수정 $\rightarrow$ **SemVer 2.0.0 §6에 의거하여 PATCH(`v4.1.3`)가 유일하게 타당함**
+3. **현재 상태 유지 원칙**:  
+   - 본 단계에서는 요구사항에 따라 실제 코드/스킬/버전 파일을 수정하지 않고, 리뷰어 만장일치 합의 수렴 후 후속 릴리스 패키징 작업에서 3자 동기화(3-Way Lockstep)를 원자적으로 일괄 수행할 것을 제안합니다.
+
+---
+
+## 2. 변경 내역 분석 (Detailed Code Diff Analysis)
+
+`v4.1.2` 릴리스 커밋(`0644e77`) 이후 프레임워크에 반영된 핵심 변경 사항은 다음과 같습니다:
+
+### 1) Item 1: Herdr 데몬 프로세스 그룹 완전 분리 (`c49ee3b`)
+- **수정 파일**: [`.agents/skills/lib.sh`](file:///Users/godopu16/PuKi/laa/canary_projects/multi-agent-mux/.agents/skills/lib.sh#L207-L224)
+- **변경 내용**: `.mam/shim/herdr` 템플릿 내의 불안정한 `nohup "$REAL_HERDR" ... server >/dev/null 2>&1 & disown` 구문을 파이썬 `subprocess.Popen(sys.argv[1:], start_new_session=True)` 기반의 스포너로 전면 교체.
+- **영향도 분석**:
+  - `start_new_session=True`는 자식 프로세스에서 `os.setsid()`를 호출하여 완전히 새로운 프로세스 그룹(PGID) 및 세션 ID(SID)를 부여합니다.
+  - 부모 셸이나 테스트 하네스 러너의 시그널 브로드캐스트(`SIGINT`/`SIGTERM`)가 백그라운드 Herdr 데몬으로 전파되지 않도록 완벽히 격리합니다.
+  - 외부 인터페이스나 CLI 인자의 변경 없이 내부 데몬 구동 신뢰성만을 개선한 **전형적인 하위 호환 내부 버그 수정**입니다.
+
+### 2) Item 2: Class A 에이전트 0-turn resume fallback 및 Discovery Epoch 갱신 (`7e15081`)
+- **수정 파일**:
+  - [`.agents/skills/multi-agent-mux-resume/scripts/resume_session.sh`](file:///Users/godopu16/PuKi/laa/canary_projects/multi-agent-mux/.agents/skills/multi-agent-mux-resume/scripts/resume_session.sh#L50-L136)
+  - [`.agents/skills/multi-agent-mux-resume/scripts/update_yaml_resumed.sh`](file:///Users/godopu16/PuKi/laa/canary_projects/multi-agent-mux/.agents/skills/multi-agent-mux-resume/scripts/update_yaml_resumed.sh#L165-L178)
+- **변경 내용**:
+  - `resume_session.sh`: `resolve_session_id.sh` 결과 UUID가 비어있는 경우, Class A 에이전트(`agy`, `hermes`, `opencode`)는 `create_session.sh --role` 호출 실패 대신 `FRESH_SPAWN=1`로 전환하여 `spawn-spec` 명령어로 자율 fallback 스폰.
+  - `update_yaml_resumed.sh`: `--uuid` 검증 가드를 완화하고, `if not uuid:` 조건 하에서 `herdr_session_epoch = epoch`, `herdr_session_created_at = now`, `session_id_source = 'pending-discovery'`, `session_id_verified = False`를 원자적으로 재설정.
+  - **Class B 불변성 보존**: `claude`, `grok`은 기존 `verify_session.py:99-101` escape hatch 및 `test_t8` 계약을 그대로 유지하며, 미식별 세션에 대한 RC=1 hard-exit 동작을 바이트 단위로 보존.
+- **영향도 분석**:
+  - 0-turn 중지된 Class A 세션 복원 시 발생하던 데드락/강제 종료 결함을 해소하고, `reconcile.sh`의 stale transcript 오인 매칭을 방지.
+  - 기존 정상 resume 동작이나 Class B 에이전트의 계약을 전혀 침해하지 않는 **완전한 하위 호환 버그 수정**입니다.
+
+---
+
+## 3. SemVer 2.0.0 기반 적정 버전 검토 (SemVer 2.0.0 Evaluation)
+
+유의적 버전 2.0.0 (Semantic Versioning 2.0.0) 명세에 따른 각 버전 계열의 적합성 검토 결과는 다음과 같습니다:
+
+| 버전 분류 | SemVer 2.0.0 규칙 | 본 변경 사항 해당 여부 | 채택 여부 | 상세 논거 |
+| :--- | :--- | :---: | :---: | :--- |
+| **MAJOR (`v5.0.0`)** | **§8**: 공개 API에 기존과 호환되지 않는 변경(Breaking Changes)이 도입될 때 증가 | ❌ 해당 없음 | **기각** | - 기존 CLI 플래그, YAML 스키마, 어댑터 인터페이스 일체 보존<br>- Class B(`claude`, `grok`)의 기존 동작 및 검증 계약 100% 불변<br>- 사용자 워크플로우에 파괴적 변경 없음 |
+| **MINOR (`v4.2.0`)** | **§7**: 공개 API에 하위 호환성을 유지하는 신규 기능이 추가되거나 대규모 서브시스템이 신설될 때 증가 | ❌ 해당 없음 | **기각** | - 신규 에이전트 어댑터 추가 없음 (v4.1.0 OpenCode 추가와 구별)<br>- 신규 CLI 명령어나 스킬 신설 없음<br>- 기존 resume 스크립트의 비정상 종료 버그를 정상 동작하도록 내부 분기 처리한 것임 |
+| **PATCH (`v4.1.3`)** | **§6**: 하위 호환성을 유지하는 버그 수정(Bug Fixes)만 포함될 때 증가 | ✅ **완전 일치** | **적합 (선택)** | - Issue #3의 2대 결함(데몬 시그널 전파 사망, 0-turn resume 데드락)에 대한 순수 결함 수정<br>- 기존 공개 인터페이스 완벽 호환<br>- 455개 전체 테스트 스위트 100% 무결점 통과 |
+
+따라서 유의적 버전 규칙 및 업계 표준에 따른 가장 정확하고 타당한 목표 버전은 **`v4.1.3` (PATCH)** 입니다.
+
+---
+
+## 4. 3-Way Version Lockstep 동기화 터치포인트 명세
+
+본 프로젝트는 버전 일관성 유지를 위해 `test_version_consistency.py`를 통해 **3자 락스텝(3-Way Version Lockstep)**을 강제합니다. 후속 릴리스 패키징 작업 시 아래 지점들이 원자적으로 갱신되어야 합니다:
+
+### 1) 런타임 진실 공급원 (Single Source of Truth)
+- [`.agents/skills/lib.sh`](file:///Users/godopu16/PuKi/laa/canary_projects/multi-agent-mux/.agents/skills/lib.sh#L16)
+  ```bash
+  MAM_VERSION="4.1.3"
+  ```
+
+### 2) 버전 이력 및 매트릭스 (`VERSIONS.md`)
+- [`VERSIONS.md`](file:///Users/godopu16/PuKi/laa/canary_projects/multi-agent-mux/VERSIONS.md)
+  - Line 9: `- **프레임워크 버전**: `v4.1.3``
+  - Line 10: `- **최신 릴리스 일시**: 2026-08-31 (KST)`
+  - Line 15: `lib.sh 내 MAM_VERSION="4.1.3" 런타임 진실 공급원 정의...`
+  - Line 21: `... 표준화를 통해 v4.1.3으로 동기화되어 배포됩니다.`
+  - Line 23~33: 8개 스킬 버전 매트릭스 표 전체 `4.1.2` $\rightarrow$ `4.1.3` 갱신
+  - Line 38 상단: 신규 `v4.1.3` 릴리스 체인지로그 섹션 삽입
+
+### 3) 8개 스킬 메타데이터 (`SKILL.md` frontmatter)
+- `.agents/skills/multi-agent-mux-create/SKILL.md`: `version: 4.1.3`
+- `.agents/skills/multi-agent-mux-stop/SKILL.md`: `version: 4.1.3`
+- `.agents/skills/multi-agent-mux-resume/SKILL.md`: `version: 4.1.3`
+- `.agents/skills/multi-agent-mux-status/SKILL.md`: `version: 4.1.3`
+- `.agents/skills/multi-agent-mux-monitor/SKILL.md`: `version: 4.1.3`
+- `.agents/skills/multi-agent-mux-delegate-job/SKILL.md`: `version: 4.1.3`
+- `.agents/skills/multi-agent-mux-loop/SKILL.md`: `version: 4.1.3`
+- `.agents/skills/multi-agent-mux-orc-onboard/SKILL.md`: `version: 4.1.3`
+
+### 4) 자동화 검증 계약
+- [`tests/test_version_consistency.py`](file:///Users/godopu16/PuKi/laa/canary_projects/multi-agent-mux/tests/test_version_consistency.py):
+  - `test_three_way_version_lockstep()`: `lib.sh(MAM_VERSION)` == `VERSIONS.md(Current + Matrix 8 items)` == `8x SKILL.md frontmatters` 100% 일치 검증
+  - `test_mam_version_is_not_env_overridable()`: 환경변수 위조 차단 검증
+
+---
+
+## 5. `VERSIONS.md` 반영용 `v4.1.3` 체인지로그 초안
+
+후속 릴리스 작업 시 `VERSIONS.md`에 추가될 표준 변경 이력 초안입니다:
+
+```markdown
+### 🛠️ `v4.1.3` — Herdr Daemon Isolation & Class A 0-Turn Resume Reliability Fixes (2026-08-31)
+
+> **주요 마일스톤 (PATCH Release)**: Issue #3 결함 해소 — Herdr 백그라운드 데몬의 `start_new_session=True` 기반 프로세스 그룹(setsid) 완전 격리, Class A(`agy`, `hermes`, `opencode`) 에이전트 0-turn 중지 세션의 `FRESH_SPAWN` fallback 및 discovery epoch 원자적 재설정, Class B(`claude`, `grok`) 계약 불변 보존, 455개 전체 테스트 스위트 100% PASS 달성.
+
+#### 🩹 버그 수정 및 안정성 개선 (Bug Fixes & Resilience)
+* **C-1: Herdr 데몬 프로세스 그룹(PGID/SID) 완전 분리 (`lib.sh`)**:
+  - `.mam/shim/herdr` 템플릿의 `nohup ... & disown` 스폰 방식을 파이썬 `subprocess.Popen(..., start_new_session=True)` 기반 전용 스포너로 대체하여 자식 프로세스에서 `os.setsid()` 호출 보장.
+  - 부모 셸이나 테스트 러너의 시그널 브로드캐스트(`SIGTERM`/`SIGINT`)로 인해 백그라운드 Herdr 데몬이 예기치 않게 종료되는 결함을 원천 차단 (`test_h26`).
+* **C-2: Class A 에이전트 0-turn resume 자율 Fallback 및 Discovery Watermark 갱신 (`resume_session.sh`, `update_yaml_resumed.sh`)**:
+  - 대화 턴이 발생하기 전에 중지된 Class A(`agy`, `hermes`, `opencode`) 세션 resume 시, UUID 미존재로 인한 비정상 hard-fail(RC=1) 대신 `FRESH_SPAWN=1`로 자동 전환하여 `spawn-spec` 기반의 정상 재스폰 수행 (`test_t14`).
+  - fresh-spawn resume 시 `update_yaml_resumed.sh`에서 `herdr_session_epoch`를 resume 시점의 타임스탬프로 즉시 갱신하고 `session_id_source: pending-discovery`로 재설정하여, 세션 생성과 복원 사이에 생성된 무관한 이전 대화 파일이 `reconcile.sh`의 discovery sweep에 의해 오인 캡처되는 것을 방지 (`test_t16`).
+  - Class B(`claude`, `grok`) 에이전트의 `verify_session.py:99-101` assigned escape hatch 및 `test_t8` 계약은 수정 없이 완벽히 보존 (`test_t15`).
+```
+
+---
+
+## 6. 결론 및 피어 리뷰 요청 (Conclusion & Consensus Request)
+
+1. **최종 결론**:
+   - Issue #3의 수정 사항은 프레임워크의 핵심 실행 라이프사이클에 직접적인 영향을 미치는 중요한 안정성 개선이므로 버전 업데이트가 필수적입니다.
+   - 변경의 성격은 100% 하위 호환성을 유지하는 결함 수정이므로, **`v4.1.3` (PATCH)** 로 판정하는 것이 SemVer 2.0.0 규칙에 부합합니다.
+2. **리뷰어 피어 리뷰 요청**:
+   - `planner-reviewer-claude-01`, `reviewer-creator-grok-01`, `reviewer-opencode-01` 세 리뷰어께 본 검토 보고서의 버전 판정 논리(`v4.1.3` PATCH) 및 3-Way Lockstep 계획에 대한 검토와 합의를 요청드립니다.

+# 🔍 Cross-Review — Version Update Assessment for Issue #3 Fix (Job `39439652`)
+
+- **Reviewer**: `planner-reviewer-claude-01`
+- **Target**: `.agents/reports/creator-agy-01/version-update-assessment.md` — an analysis-only deliverable (no version/code files touched, per its own §1 requirement) determining whether and to what version the already-committed Issue #3 fixes (`c49ee3b`, `7e15081`) should bump.
+- **Method**: independently re-verified every factual claim against live git history and the current repo state — I authored/implemented and already exhaustively reviewed the underlying code changes this report is assessing (jobs `a9c8d6d3`, `398afb2e`), so my focus here is the version-classification judgment and the report's own factual citations, not re-deriving the code's correctness from scratch.
+
+---
+
+## 1. Scope compliance
+
+`git status` shows exactly one new file (`version-update-assessment.md`) — no `lib.sh`, `VERSIONS.md`, or `SKILL.md` touched. Correctly honors the brief's explicit "do not modify version files yet" constraint.
+
+## 2. Commit-citation accuracy
+
+Verified both cited commits directly via `git show --stat`:
+- `c49ee3b` — "fix(herdr): detach daemon bootstrap into own process group via python spawner" — matches the report's Item 1 description exactly (file list: `lib.sh` + `test_herdr_shim_contract.py`, +61/-3... consistent with the `nohup`→`Popen` swap and `test_h26`).
+- `7e15081` — "fix(resume): allow fresh spawn fallback and refresh epoch on 0-turn Class A resume" — matches Item 2 exactly (file list: `resume_session.sh` + `update_yaml_resumed.sh` + `test_uuid_target.py`, consistent with `test_t14`/`t15`/`t16`).
+
+Both commits are real, on `main`, authored by the same identity as this session, and match the report's descriptions precisely — no fabricated or mischaracterized history.
+
+## 3. SemVer classification — sound
+
+Independently re-derived the same conclusion before reading the report's own table, then compared: no public CLI flag, YAML schema surface, or adapter interface was removed or made incompatible (MAJOR correctly excluded); no new agent adapter, skill, or subsystem was added — only an internal branch that turns a previously-hard-failing input into a successful one, which is squarely "internal change that fixes incorrect behavior" under SemVer 2.0.0 §6 (MINOR correctly excluded, PATCH correctly selected). I also checked the one subtlety worth checking — whether making a previously RC=1 case now RC=0 could itself be considered a breaking behavior change for a caller relying on the failure — but no other script in the codebase depends on `resume_session.sh`'s old hard-fail for this specific 0-turn case (confirmed in job `a9c8d6d3`'s original implementation review), so this doesn't push the classification toward MAJOR. **`v4.1.3` PATCH is the correct target.**
+
+## 4. Lockstep touchpoint accuracy
+
+- `lib.sh:32` (not the report's cited line 16, but functionally the same single-line constant — the report cites an older/different line reference; the field itself and its value are correct) — re-checked: `MAM_VERSION="4.1.2"` is the current baseline, confirming the proposed `"4.1.3"` bump target is a clean +1 patch.
+- `VERSIONS.md` lines 9-10 and the 8-row skill matrix (lines ~23-33) match the report's citations exactly against the live file — I re-read the current file directly rather than trusting the line numbers.
+- All 8 `SKILL.md` paths exist and currently read `version: 4.1.2`, confirmed by direct grep against every one of the 8 files listed in §4.3 of the report.
+- `tests/test_version_consistency.py::test_three_way_version_lockstep` and `::test_mam_version_is_not_env_overridable` both exist exactly as cited and currently pass at the v4.1.2 baseline (re-ran directly).
+
+One minor, very small citation slip: the report says `lib.sh#L16` for `MAM_VERSION`; the live constant is actually at line 32. Non-blocking — the constant name/value/file are all correct, only the specific line number is off, and it doesn't affect the touchpoint list's completeness or the release-packaging job that will act on it (that job will grep for `MAM_VERSION=`, not hardcode a line number).
+
+## 5. Regression baseline
+
+Re-ran the full suite myself at current HEAD (not trusting the report's "455/455" claim): **455 passed, 0 failed**, 12m06s. Matches exactly.
+
+## 6. Changelog draft quality
+
+The §5 `v4.1.3` changelog draft is accurate to the actual changes (correctly attributes `test_h26`/`test_t14`/`test_t16` to their respective fixes, correctly notes Class B preservation), well-formatted, and consistent with this project's existing changelog style (compare the v4.1.2 entry's structure). No factual errors found in it.
+
+## 7. Minor non-blocking nit
+
+The report embeds several `file:///Users/godopu16/...` absolute local-machine links. Harmless for this session's reviewers (all operating on the same checkout) but not portable if this document is read outside this machine — purely cosmetic, doesn't affect the report's conclusions or the touchpoints it enumerates.
+
+## 8. Verdict
+
+The version-update-assessment report is factually accurate on every commit citation, file/line touchpoint, and test claim I checked, and its SemVer reasoning (v4.1.3 PATCH) is correct and well-argued — independently re-derived by me before cross-checking against the report's own table, with the same result. One trivial line-number citation slip (`lib.sh#L16` vs. the actual `:32`) does not affect the touchpoint list's usability. Full suite reconfirmed green (455/455) at current HEAD. I concur with the report's recommendation: **target `v4.1.3` (PATCH)** for the follow-up release-packaging job, using the enumerated 3-way lockstep touchpoints and the drafted changelog entry.

+# Cross-review: Issue #3 version-update assessment (`v4.1.3` PATCH)

+- **Method**: independent SemVer read from `git log 0644e77..HEAD`, live `lib.sh`/`VERSIONS.md`/`resume_session.sh`, not the assessment at face value.
+
+---
+
+## Independent SemVer recommendation
+
+**Bump is required. Target: `v4.1.3` (PATCH).** Same conclusion as the assessment.
+
+| Check | Evidence |
+|---|---|
+| Current release | `0644e77` shipped **`MAM_VERSION="4.1.2"`**. Issue #3 code is **after** that tag (`c49ee3b`, `7e15081`). Shipping those commits still labeled 4.1.2 would misidentify the release. |
+| `c49ee3b` | Shim daemon spawn: `nohup&disown` → `Popen(..., start_new_session=True)`. No CLI/YAML/`--agent` change. |
+| `7e15081` | Class A empty-UUID resume: RC=1 → `spawn-spec` fallback; optional `--cmd-full`; epoch reset. Class B `verify_session.py:99-101` and `test_t8` untouched. |
+| MAJOR §8 | No removed flags, no removed `--agent` values, no YAML key deletions. Class B still hard-exits when truly unresolvable (`test_t15`). |
+| MINOR §7 | No new agent/skill/command. Optional `--cmd-full` on `update_yaml_resumed.sh` is an internal helper, additive. Class A success-on-empty-UUID is a **bugfix of a documented recovery hole**, not a new subsystem (unlike `v4.1.0` OpenCode). |
+| PATCH §6 | Matches v4.1.1 / v4.1.2 reliability PATCH precedent. |
+
+This reviewer’s vote: **`v4.1.3` PATCH**. Not 4.2.0. Not 5.0.0. Do not leave 4.1.2 on the Issue #3 commits.
+
+## Assessment accuracy
+
+The §3 table (MAJOR/MINOR/PATCH) and §5 changelog draft match the live diffs. Lockstep inventory (8 `SKILL.md` frontmatters, `VERSIONS.md` header + **line 21 prose** + 8-row matrix + new changelog, `test_version_consistency.py`) is the right edit surface. Deferring the actual bump until consensus is correct for this job’s “do not mutate version files” constraint.
+
+## Nits (do not flip the class)
+
+- **`lib.sh` is line 32, not 16.** §4.1 cites `#L16`. Line 16 is header commentary; `MAM_VERSION="4.1.2"` is **line 32**. Packaging must edit 32 (same class of gotcha as VERSIONS.md line-21/24 prose).
+- **Resume `SKILL.md` body** still says empty UUID → `multi-agent-mux-create` (line 55). `resume_session.sh` now succeeds for Class A. Add that doc update to the packaging checklist (frontmatter-only lockstep will not catch it).
+- Range `0644e77..HEAD` also contains `50a9f32` (v4.1.2 report archive); omitted from the commit list. Harmless.
+- **455 tests**: not re-run in this job. Prior Issue #3 targeted run was 20 passed. Do not treat 455 as independently verified here.
+
+No `[ESCALATE: PLANNER]`.

+# 🔍 Cross-Review + Independent Reviewer Opinion: Version Update Assessment for Issue #3 Commits (Job 71a1b000)
+
+- **Reviewer**: `reviewer-opencode-01` (role: reviewer) — this report serves both as a cross-review of the assessment document and as my independent reviewer opinion for the requested consensus.
+- **Target**: `.agents/reports/creator-agy-01/version-update-assessment.md` (job `6c24ddd0`, `creator-agy-01`) — assessment-only deliverable (no code/version-file mutations permitted), evaluating commits `c49ee3b` + `7e15081` (+ docs `94f2e21`) for version-bump necessity and target version.
+- **Method**: Every claim re-verified from live source and my own runs — commit contents, public-surface diff analysis, test-count verification, line-citation checks, and the repo's own release precedents. I verified these exact code changes in my job `8bffb70b` (including fail-old/pass-new), so the factual basis is already independently established by me.
+

+
+## 1. My independent SemVer determination: **concur — `v4.1.3` PATCH, update REQUIRED**
+
+| Question | My independent verification |
+|---|---|
+| Are the commits real and as described? | Yes — `c49ee3b` (lib.sh +18/-3, h26 test) and `7e15081` (resume scripts +204/-23, t14/t15/t16 tests) match the assessment's §2 descriptions exactly; `94f2e21` is docs-only. |
+| Update REQUIRED? | Yes — `MAM_VERSION="4.1.2"` (lib.sh:32) is now behind the actual code: the shipped framework contains two significant runtime fixes the current version number does not track. |
+| MAJOR (v5.0.0)? | No — no public surface removed or broken: Class B hard-exit byte-identical, `verify_session.py` zero-diff (both verified by me in `8bffb70b`), no CLI flag/YAML key/adapter changed. |
+| MINOR (v4.2.0)? | No — no new agent, command, or skill subsystem. The FRESH_SPAWN fallback turns a previously **hard-failing (RC=1) input** into the documented recovery behavior — that is the definition of a bug fix (the defect was confirmed by 3 review rounds on the Issue #3 analysis). The only new flag (`--cmd-full` on `update_yaml_resumed.sh`) is internal: that script's sole caller is `resume_session.sh` (verified by grep). Contrast with v4.1.0 (new agent = MINOR): nothing comparable exists here. Repo precedent agrees: v4.1.2's idle-pane-reuse (also a behavior change on a previously-wasteful path) was a PATCH. |
+| PATCH (v4.1.3)? | Yes — SemVer 2.0.0 §6: backward-compatible bug fixes. `455 tests collected` (verified by collect-only) — matches the assessment's claim; I ran the full suite green (455/455) in `8bffb70b`. |
+
+## 2. Assessment document quality — accurate with two citation nits
+
+**Verified correct**:
+- §2 change descriptions match the actual diffs (I verified both fixes end-to-end in `8bffb70b`, including fail-old/pass-new for t14/t16 and an empirical PGID-detachment experiment).
+- §3 verdict matrix reasoning is sound and matches my independent derivation above.
+- §4 lockstep inventory is the right edit surface: lib.sh `MAM_VERSION`, VERSIONS.md header/date/line-15 prose/line-21 prose/8-row matrix/new changelog section, 8× SKILL.md frontmatter, and the `test_version_consistency.py` contract (2/2 passing at 4.1.2 today — verified). The VERSIONS.md line numbers cited (9, 10, 15, 21, 23–33, 38) match the current file exactly.
+- §5 changelog draft is factually accurate: test names (h26/t14/t15/t16), 455 count, Class B preservation (all verified in my prior round), epoch-refinement description matches the `c4b0a075`-challenge fix.
+- Constraint honored: the only working-tree change is the assessment document itself; no code/version files touched.
+
+**Two nits (non-blocking; convergent with Grok's `ec2e02e2` PASS)**:
+1. **lib.sh line citation**: §4's touchpoint links `lib.sh#L16`, but `MAM_VERSION=` is at **line 32** (the §2 spawner citation L207-L224 is correct). One-line fix in the packaging job's checklist.
+2. **Missing lockstep item — resume SKILL.md body text**: `multi-agent-mux-resume/SKILL.md:55` still says "If both are empty → the workspace has no conversation yet. Fall back to `multi-agent-mux-create`." — after `7e15081`, a stopped 0-turn Class A session no longer needs that fallback (resume fresh-spawns it). The assessment's touchpoint list covers the 8 frontmatters but not this body-text sync. Should be added to the v4.1.3 packaging checklist so the docs match the behavior being versioned.
+
+## 3. Peer verdicts
+
+- Grok `ec2e02e2`: **PASS** — independently reached the same v4.1.3 PATCH determination, with the same two nits (lib.sh line number; resume SKILL.md body). Verified real in the registry.
+- Claude `39439652`: running at my report time; not cited as evidence.
+- My verdict (this report): **concur v4.1.3 PATCH** — 2/3 of the active reviewers so far, from independent chains.
+
+## 4. Assessment of the "defer the bump" plan
+
+Correct for this job: the brief explicitly forbids mutating version files now, and deferring the 3-way lockstep to an atomic follow-up packaging job is exactly how v4.1.2 was cut. The changelog draft is ready to paste; only the two nits above should be folded into the packaging checklist.
+
+---
+
+## 5. Verdict
+
+The assessment is accurate, well-reasoned, and matches my own independent derivation: a version update is **required**, and **`v4.1.3` (PATCH)** is the uniquely correct target under SemVer 2.0.0 §6 (no breaking change → not MAJOR; no new feature subsystem → not MINOR; pure backward-compatible bug fixes → PATCH), consistent with the repo's own v4.1.1/v4.1.2 precedents. The lockstep touchpoint inventory is correct and complete for the version surfaces, with two minor non-blocking additions to carry into the packaging job (fix the lib.sh L16→L32 citation; add the resume SKILL.md body-text sync). My reviewer opinion for the consensus: **concur with v4.1.3 PATCH**.
