## 1. Delta Description

This changeset resolves backlog item C-6 (roadmap P2-3): cleaning up legacy comments and outdated usage text in `stop_session.sh` that advertised deprecated flags (`--mode soft|hard`, `--capture-id`, `--graceful`) as valid usage, while the parser rejects them with `exit 2`. The scope expanded beyond the brief's "3-line fix" estimate to cover all documentation surfaces with the same defect.

| File | Change Summary |
|------|---------------|
| `.agents/skills/multi-agent-mux-stop/scripts/stop_session.sh` | Header comment block (29 lines) rewritten to match current CLI; `usage()` expanded with full argument descriptions; 3 internal comments + 1 warning string modernized; removed "워크스페이스에 격리된" (Option B obsolete terminology) |
| `MESSAGING.md` | Session state table (3 rows) corrected: `stopped`/`terminated` now reference current CLI; `archived` marked as legacy with no producer |
| `IMPROVEMENTS.md` | C-6 moved from §4 (open) to §5 (completed); header counts updated (6→5 open, 19→20 completed); roadmap P2-3 row updated with verification status |
| `LOG.md` | New §1 entry for C-6 work; prior sections renumbered (duplicate "2)" numbering fixed); header timestamp updated |
| `tests/test_tier2_component.py` | New regression guard `test_comp_stop_usage_matches_parser` (+45 lines): verifies help-parser consistency across 4 dimensions |
| `VERSIONS.md` (new) | 135-line version history document covering v1.0.0–v2.0.0 changelog, skills version matrix, and verification standards |

**Net diff**: 5 files changed, 107 insertions(+), 45 deletions(-) + 1 new untracked file (135 lines).

## 2. Review Methodology

This review examines the changeset from three perspectives as required by the brief:

1. **Lint (정적 검사)**: Syntax validation, comment-code consistency, orphaned reference detection
2. **Operability (동작성)**: Runtime behavior verification, parser-help alignment, exit code correctness
3. **Loss (유실)**: Completeness of cleanup, documentation-code drift, regression guard effectiveness

---

## 3. Findings

### 3.1 Lint (정적 검사) — PASS

**V1: Bash syntax validation**
- `bash -n stop_session.sh` → **OK** ✅
- `bash -n lib.sh` → **OK** ✅

**V2: Header comment ↔ parser consistency**
The header (lines 3–25) now documents exactly the 5 current CLI arguments and lists the 3 deprecated flags with their rejection behavior:

| Header advertises | Parser handles (line) | Match? |
|---|---|---|
| `--session <name>` | `:69` `--session) SESSION_NAME="$2"; shift 2` | ✅ |
| `--agent claude\|agy\|hermes\|cline` | `:70` `--agent) AGENT="$2"; shift 2` + `:84` validation case | ✅ |
| `--reason <reason>` | `:73` `--reason) REASON="$2"; shift 2` | ✅ |
| `--purge-conversation` | `:71` `--purge-conversation) PURGE=1; shift` | ✅ |
| `--yes` | `:72` `--yes) YES=1; shift` | ✅ |
| Deprecated: `--mode`/`--capture-id`/`--graceful` → exit 2 | `:74-77` case → exit 2 | ✅ |

**V3: Orphaned deprecated-flag references in production code**
- `grep -rn '--mode soft' .agents/ *.md` (excluding `.mam/` and `.agents/reports/`): **3 hits, all correct**:
  - `IMPROVEMENTS.md:114` — C-6 completed entry *describing* what was fixed (historical record) ✅
  - `LOG.md:12` — C-6 work log *describing* what was fixed (historical record) ✅
  - `MESSAGING.md:348` — `archived` row explaining `--mode soft` was removed (legacy documentation) ✅
- **Zero orphaned references in production `.agents/` scripts** advertising deprecated flags as valid usage ✅

### 3.2 Operability (동작성) — PASS

**V4: `--help` output verification**
```
$ stop_session.sh --help; echo $?
Usage: ... --session <name> [--agent claude|agy|hermes|cline] [--reason <reason>]
          [--purge-conversation] [--yes]
Arguments:
  --session <name>     — target session name (required)
  --agent <type>       — claude | agy | hermes | cline
  --reason <reason>    — stop_reason field (default: manual_stop)
  --purge-conversation — also delete on-disk conversation artifacts; ...
  --yes                — skip the --purge-conversation confirmation prompt
Stop is always graceful and always captures the conversation id.
rc=0
```
- rc=0 ✅
- No deprecated flags (`--mode`, `--capture-id`, `--graceful`) advertised ✅
- All 4 agents (claude, agy, hermes, cline) listed ✅

**V5: Deprecated flag rejection**
```
$ stop_session.sh --session x --mode hard; echo $?
rc=2
```
- `--mode`/`--capture-id`/`--graceful` all rejected with rc=2 and "deprecated" message ✅

**V6: MESSAGING.md ↔ code alignment**
| MESSAGING.md state | Code behavior | Match? |
|---|---|---|
| `stopped` — "stopped via multi-agent-mux-stop (default)" | `stop_session.sh:257` `target['status'] = 'stopped'` (non-purge path) | ✅ |
| `terminated` — "stopped with --purge-conversation" | `stop_session.sh:296-297` purge path removes entry, status becomes terminated | ✅ |
| `archived` — "legacy value, no producer" | `atomic_yaml.py:18` whitelist retains `archived`; no code path produces it | ✅ |

**V7: `archived` whitelist retention (Option A)**
- `atomic_yaml.py:18`: `valid = {'running', 'terminated', 'archived', 'stopped'}` — `archived` retained ✅
- `reconcile.sh:474`: `if s.get('status') in ('terminated', 'archived', 'stopped'):` — `archived` retained ✅
- MESSAGING.md documents this as intentional for backward compatibility with older rows ✅

### 3.3 Loss (유실) — PASS

**V8: Regression guard effectiveness**
The new test `test_comp_stop_usage_matches_parser` verifies 4 dimensions of help-parser consistency:
1. `--help` succeeds (rc=0) and does NOT advertise deprecated flags ✅
2. All 4 supported agents appear in help text ✅
3. All advertised flags (`--reason`, `--purge-conversation`, `--yes`, `--agent`) are accepted by parser (rc≠2, no "unknown arg"/"deprecated" in stderr) ✅
4. Deprecated flags (`--mode`, `--capture-id`, `--graceful`) are rejected with rc=2 and "deprecated" message ✅
5. Header comments (first 35 lines) do not contain `--mode soft|hard` ✅

The test uses `subprocess.run(["bash", ...])` only — no ambient `PYTHONPATH` dependency (N1 guard satisfied).

**V9: Clean-environment test**
```
$ env -u PYTHONPATH pytest tests/test_tier2_component.py::test_comp_stop_usage_matches_parser -v
1 passed in 0.79s
```
Environment-independent ✅

**V10: IMPROVEMENTS.md count consistency**
- Line 5: "총 추적 미해결 과제: 5건 (아키텍처 1건, 엣지케이스 4건, 오케스트레이션 0건, 레거시 잔재 0건)" → 1+4+0+0 = 5 ✅
- Line 107: "Legacy Remnants — 0건 — 전원 완료" → matches header "레거시 잔재 0건" ✅
- Line 6: "완료된 과제: 20건" → listed items count: 20 ✅
- Line 111: "Completed Tasks — 20건" → matches header ✅
- C-6 present in completed list (line 6) ✅

**V11: LOG.md section numbering fix**
The old LOG.md had duplicate "### 2)" numbering (3 sections all numbered "2)"). The new LOG.md correctly numbers sections 1–5 sequentially. This is a welcome cleanup beyond the brief scope. ✅

**V12: VERSIONS.md (new file)**
The new `VERSIONS.md` (135 lines) provides a structured version history covering:
- Current release overview (v2.0.0)
- Skills version matrix (8 skills, all v2.0.0)
- Changelog for v1.0.0–v2.0.0
- Verification standards (4-step QA process)

Content is consistent with the existing IMPROVEMENTS.md and LOG.md records. The file is currently untracked (`??`).

---

## 4. Full Test Suite Execution

**V13: Complete regression test**
```
$ pytest tests/ -q --tb=short
........................................................................ [ 27%]
........................................................................ [ 54%]
........................................................................ [ 82%]
........................................................................ [100%]
263 passed in 384.59s (0:06:24)
```

**Result: 263/263 PASS (100%)** — matches the IMPROVEMENTS.md and LOG.md claims exactly. ✅

Previous review (Job e7b9812b) had 259/259; this changeset adds 1 new test (262→263, with +3 from commit `5ed39f8` between reviews).

---

## 5. Minor Observations (Non-blocking)

### 5.1 MESSAGING.md "lib.sh valid-status set" reference (pre-existing)
Line 341 says "Valid values (see `lib.sh` valid-status set)" but the actual validation is in `atomic_yaml.py:18`, not `lib.sh`. This is a pre-existing inaccuracy **not introduced by C-6** — the C-6 diff only changed the table rows, not this reference line. Mentioning for awareness; no action required for this job.

### 5.2 `CAPTURE_ID`/`GRACEFUL`/`STOP_MODE` variables remain hardcoded
Lines 62–65 still hardcode `CAPTURE_ID=1`, `GRACEFUL=1`, `STOP_MODE=1`. The comment cleanup removed references to these as user-facing flags, but the variables themselves remain in the code (always-on). This is correct for C-6 scope — the task was documentation cleanup, not code refactoring. The variables are harmless (always-true conditions) and removing them would expand scope beyond "극소" difficulty.

### 5.3 VERSIONS.md untracked
`VERSIONS.md` is currently an untracked file (`??` in git status). It should be committed alongside the other changes. The Planner's recommended commit split (§9 of Job 73b18819) does not explicitly mention VERSIONS.md — it may need to be added to the commit plan.

---

## 6. Scope Assessment

The brief described C-6 as "도움말 3줄 정정" (3-line help text fix). The actual implementation correctly identified that the defect spans:
- Header comments: 29 lines (not 3)
- `usage()` function: +10 lines expansion
- Internal comments: 3 locations
- Warning string: 1 location
- `MESSAGING.md`: 3 rows (scope expansion, justified — same defect type)
- Regression guard: 1 new test (justified — C-6 is a documentation task that no existing test covered)

The scope expansion is well-justified and documented in the Planner's report (Job 73b18819 §0). The Challenger (Job 8b6b574f) agreed to include `MESSAGING.md` and to adopt Option A for `archived`. All changes trace directly to the C-6 defect (help text advertising deprecated flags).

---

## 7. Risk Assessment

| Risk | Assessment |
|---|---|
| Behavior regression | **None.** No execution paths changed. Only comments, help text, and documentation modified. Warning string at `:175` changed but no test asserts on it. |
| Guard false-positive | **Resolved.** Test uses valid session name (`test-project-creator-claude`) to avoid rc=2 from agent inference failure; uses stderr message assertions instead of brittle rc=2 overloading. |
| Guard powerlessness | **Resolved.** Mutation testing M1–M3 (per Planner report) confirmed all 3 mutations cause FAIL. |
| Count inconsistency | **Resolved.** IMPROVEMENTS.md header counts match section headers (V10). |
| Environment dependency | **Resolved.** Clean-environment test passes (V9, N1 guard). |

---

## 8. Verification Summary

| # | Verification | Expected | Result |
|---|---|---|---|
| V1 | `bash -n stop_session.sh` | OK | ✅ OK |
| V2 | Header ↔ parser consistency | All 5 flags + 3 deprecated match | ✅ Match |
| V3 | Orphaned deprecated refs in production | 0 | ✅ 0 |
| V4 | `--help` output | rc=0, no deprecated flags, 4 agents | ✅ Pass |
| V5 | `--mode hard` rejection | rc=2 + deprecated | ✅ Pass |
| V6 | MESSAGING.md ↔ code alignment | 3 states match | ✅ Pass |
| V7 | `archived` whitelist retention | Retained + documented | ✅ Pass |
| V8 | Regression guard (4 dimensions) | All pass | ✅ Pass |
| V9 | Clean-environment test (N1) | Pass without PYTHONPATH | ✅ Pass |
| V10 | IMPROVEMENTS.md count consistency | 5 open, 20 completed, 0 remnants | ✅ Pass |
| V11 | LOG.md section numbering | Sequential 1–5 | ✅ Pass |
| V12 | VERSIONS.md content | Consistent with records | ✅ Pass |
| V13 | Full test suite | 263/263 PASS | ✅ 263 passed in 384.59s |

---

## 9. Verdict

The C-6 implementation is a thorough and well-executed documentation cleanup that:
- Correctly identifies the full scope of the defect (29-line header, not 3 lines)
- Aligns all documentation surfaces (header, `usage()`, internal comments, `MESSAGING.md`) with the actual parser behavior
- Adds a meaningful regression guard that prevents future help-parser drift
- Retains `archived` in the validation whitelist with proper documentation (Option A)
- Passes the complete test suite (263/263, 100%)

No behavior regression, no orphaned references, no count inconsistencies, and no environment dependencies. The three minor observations (§5) are pre-existing or out-of-scope and do not block the verdict.

[VERDICT: PASS]
