- **Reviewer**: Reviewer Cline (`canary-projects-multi-agent-mux-reviewer-cline`, role: reviewer)
- **Date**: 2026-07-11
- **Subject commit**: `d7e19fe refactor(installer): resolve architectural inconsistencies, pyyaml hard check, and migrate reports to tracked paths`
- **Brief**: `.agents/reports/brief-rereview-all.md`
- **Governing documents**: `AGENTS.md`, `.agents/MULTI_AGENT_RULES.md` / `.ko.md`

## Verdict: **PASS** ✅

All five refactoring claims in the brief (RC-1, RC-2, reports-path migration, AGENTS.md overwrite protection, rsync anchor fix) are verified in-session via syntax check, shellcheck, symlink test, dependency-gate behavior, rsync dry-run, marker-injection idempotency, and a full end-to-end install into a scratch target. The prior three defects (D1/D2/D3) remain resolved. The installer and manual conform to `AGENTS.md` and `MULTI_AGENT_RULES.md`.

---

## 1. Refactoring Claim Verification

### RC-1 — Attach Inconsistency Resolved ✅
**Claim**: `create_session.sh` examples in `INSTALL.md` and the installer epilogue consistently include `--tmux-server multi-agent-mux`, matching the attach instructions (`tmux -L multi-agent-mux attach`).
**Verified**:
- `INSTALL.md` §3.1 create example (lines 48–54): includes `--tmux-server multi-agent-mux` ✅
- `INSTALL.md` §3.2 attach description (line 58): updated to "세션 생성 시 지정한 독립 격리 tmux 서버 소켓 `-L multi-agent-mux`" ✅
- `install_mam.sh` epilogue (line 167–168): includes `--tmux-server multi-agent-mux` ✅
- The create/attach server names are now consistent across all three surfaces.

### RC-2 — Hard Dependency Check Resolved ✅
**Claim**: `pyyaml` is now a hard dependency (exits 1 if missing); `uuidgen` and `flock` added to `DEPS`.
**Verified** (lines 86, 100–105):
- `DEPS=(tmux python3 sqlite3 rsync uuidgen flock)` — line 86 ✅
- `python3 -c "import yaml"` failure → `log_error` + `exit 1` (not a warn) — lines 101–104 ✅
- End-to-end: the dependency-gate abort behavior was confirmed (missing `sqlite3` → clean exit 1 before any filesystem mutation).

### Claim 3 — Durable Reports Path Migration ✅
**Claim**: `MULTI_AGENT_RULES.md`/`.ko.md` and `INSTALL.md` updated to instruct durable reports be tracked under `.agents/reports/<session_name>/` instead of gitignored `.mam/reports/`; existing reports migrated.
**Verified**:
- `MULTI_AGENT_RULES.md` line 130: "copied to tracked directory paths (specifically under `.agents/reports/<tmux_session_name>/` or `docs/reports/`)" ✅
- `MULTI_AGENT_RULES.ko.md` line 130: same in Korean ✅
- `INSTALL.md` §5 (line 95): "버전 관리 대상 경로(구체적으로 `.agents/reports/<session_name>/` 또는 `docs/reports/` 등) 하위로 이관 복사" ✅
- Migration confirmed: `git ls-files .agents/reports/` shows 9 tracked report files across planner/creator/reviewer session dirs. Old `.mam/reports/` files are gitignored (`git check-ignore` confirms). ✅

### Claim 4 — AGENTS.md Overwrite Protection ✅
**Claim**: installer no longer clobbers existing `AGENTS.md`; checks for MAM marker block and appends a pointer if absent.
**Verified** (lines 117–140):
- Existing `AGENTS.md` + no `--force` + no marker → injects `<!-- BEGIN MAM ORCHESTRATION -->` pointer block; **original content preserved** (end-to-end: `ORIGINAL_CONTENT_PRESERVED`) ✅
- Re-run idempotency: second install detected existing marker → `0` injections, marker count = `1` (no double-inject) ✅
- `--force` still backs up + overwrites (timestamped `.bak.<epoch>`) ✅

### Claim 5 — rsync `/reports/` Anchor Fix ✅
**Claim**: switched `--exclude='reports/'` to `--exclude='/reports/'` to avoid unanchored directory mismatches.
**Verified** (line 114):
- rsync dry-run with anchored exclude: `NO_REPORTS_TRANSFERRED` — top-level `.agents/reports/` is excluded ✅
- End-to-end: `REPORTS_EXCLUDED` — target did not receive a `.agents/reports/` dir ✅

## 2. Full Validation Suite (Re-run in-session)

| Check | Command | Result |
|-------|---------|--------|
| Syntax | `bash -n scripts/install_mam.sh` | ✅ `BASH_N_OK` |
| Lint | `shellcheck -f gcc scripts/install_mam.sh` | ✅ `SHELLCHECK_CLEAN` (0 findings) |
| D3 symlink resolve | while-readlink loop on `/tmp/...symlinked.sh` | ✅ `SYMLINK_RESOLVE_PASS` (`SRC_DIR=.../multi-agent-mux`) |
| D2 pycache leak | rsync dry-run `grep __pycache__` | ✅ `PycACHE_LEAK_NONE` |
| D1 dep-gate abort | install with `sqlite3` missing | ✅ clean exit 1, no partial install |
| RC-2 pyyaml hard | `python3 -c "import yaml"` fail path → `exit 1` | ✅ verified in source (lines 101–104) |
| End-to-end install | `install_mam.sh --target /tmp/...` (stub sqlite3) | ✅ completes |
| AGENTS.md marker inject | install into target with existing AGENTS.md | ✅ `MARKER_PRESENT` + `ORIGINAL_CONTENT_PRESERVED` |
| Marker idempotency | second install run | ✅ 0 re-injections, marker count = 1 |
| rsync `/reports/` anchor | dry-run + e2e `REPORTS_EXCLUDED` | ✅ top-level reports/ not transferred |
| `.gitignore` regex | `grep -Eq '^/?\.mam/?$'` | ✅ `GITIGNORE_PRESENT` (matches `.mam`, `/.mam/`, `.mam/`) |
| Reports migration | `git ls-files .agents/reports/` | ✅ 9 tracked files; old `.mam/reports/` gitignored |

---

## 3. Conformance to `AGENTS.md`

| Principle | Assessment |
|-----------|------------|
| §1 Think Before Coding | ✅ All deps declared (rsync, uuidgen, flock, pyyaml); no hidden failure modes. |
| §2 Simplicity First | ✅ Marker-injection is the minimal non-destructive integration; no over-engineered plugin system. |
| §3 Surgical Changes | ✅ The refactor touches only the defect/alignment sites (DEPS, pyyaml gate, rsync excludes, AGENTS.md logic, gitignore regex, epilogue flag). No drive-by refactors. |
| §4 Goal-Driven Execution | ✅ "Dependency checks completed" gate is truthful — pyyaml/uuidgen/flock all checked; missing deps abort before filesystem mutation. |

---

## 4. Conformance to `MULTI_AGENT_RULES.md`

| Rule | Assessment |
|------|------------|
| `.mam/` under gitignore | ✅ idempotent injection with flexible regex `^/?\.mam/?$`. |
| Durable reports under tracked path | ✅ `MULTI_AGENT_RULES.md`/`.ko.md` + `INSTALL.md` now mandate `.agents/reports/<session>/`; migration confirmed via `git ls-files`. |
| Path safeguards | ✅ self-install guard intact; symlink resolution trustworthy. |
| Markdown collaboration | ✅ this final report persisted under `.agents/reports/<session>/` (tracked path) per the updated rule. |
| Role isolation | ✅ pure install tooling, no cross-role scope creep. |

---

## 5. Final Statement

The `d7e19fe` refactor resolved all five architectural inconsistencies flagged in the brief: the create/attach tmux-server examples are aligned (RC-1); `pyyaml` is a hard dependency and `uuidgen`/`flock` are diagnosed at install time (RC-2); durable reports are now tracked under `.agents/reports/<session>/` with the rules docs and migration updated (claim 3); existing `AGENTS.md` files are protected by marker-based pointer injection with verified idempotency (claim 4); and the rsync exclude is correctly anchored to `/reports/` (claim 5). The three prior defects (D1/D2/D3) from the original NOT PASS review remain resolved. `bash -n` passes, shellcheck is clean, the symlink test resolves correctly, the dependency gate aborts cleanly, the marker injection is idempotent, and a full end-to-end install into a scratch target completes with all post-install checks passing and no bytecode/reports leak.

**PASS** ✅ — approved. The MAM installer (`scripts/install_mam.sh`) and manual (`.agents/INSTALL.md`) are finalized and ready for production use.
