+# 🛠️ Multi-Agent Mux (MAM) 설치 및 적용 가이드
+
+MAM은 단일 워크스페이스 상에서 복수의 에이전트(Claude, Cline, Agy, Hermes 등)들이 서로의 상태를 오염시키지 않고 협업할 수 있도록 프로세스 격리 및 라이프사이클 관리를 제공하는 프레임워크입니다.
+
+이 가이드는 기존의 다른 프로젝트/레포지토리에 MAM을 신속하게 도입하고 적용하는 절차를 설명합니다.
+
+---
+
+## 1. ⚙️ 사전 요구사항
+MAM 스킬 및 스크립트들은 호스트 시스템의 다음 도구들에 의존합니다. 설치 전에 확인해 주세요.
+*   **tmux**: 에이전트를 백그라운드 격리 Pane에서 구동하기 위한 프로세스 컨테이너
+*   **python3**: 세션 레지스트리(YAML/SQLite DB) 파싱 및 유효성 검사
+*   **sqlite3**: 트랜잭션 안전성 및 오케스트레이션 락 보장
+*   **rsync**: `.agents/` 오케스트레이터 및 스킬 폴더 복제 및 동기화
+*   **python3-yaml (pyyaml)**: 세션 데이터 YAML 저장 및 로드 의존성 (`pip install pyyaml`)
+
+---
+
+## 2. 🚀 자동 설치 방법
+
+MAM의 자동 설치 스크립트(`install_mam.sh`)를 사용하여 10초 만에 필요한 규칙과 라이프사이클 툴킷을 타겟 프로젝트에 이식할 수 있습니다.
+
+### 설치 스크립트 실행
+MAM 레포지토리 루트에서 다음 명령어를 실행합니다.
+```bash
+# 기본 사용법 (타겟 프로젝트 경로 지정)
+$ bash scripts/install_mam.sh --target /path/to/your/project
+
+# 만약 이미 타겟에 AGENTS.md 가 존재하여 강제로 덮어쓰고 싶다면:
+$ bash scripts/install_mam.sh --target /path/to/your/project --force
+```
+
+### 설치 스크립트가 수행하는 작업:
+1.  **의존성 진단**: 시스템에 `tmux`, `python3`, `sqlite3` 가 설치되어 있는지 확인합니다.
+2.  **규칙 및 스킬 복제**: 오케스트레이션 가이드(`.agents/` 하위 전체)를 타겟 프로젝트 하위로 이식합니다.
+3.  **지침 전파**: 에이전트가 로드하고 복종할 행동 지침 문서(`AGENTS.md`)를 프로젝트 루트에 복사합니다.
+4.  **형상 제외 설정**: 세션 DB 및 격리 캐시 저장소인 `.mam/` 디렉토리를 타겟 프로젝트의 `.gitignore` 에 자동 주입하여 불필요한 형상 관리를 방지합니다.
+
+---
+
+## 3. 🎯 핵심 사용 워크플로우 (Quick Start)
+
+설치가 완료되면, 타겟 프로젝트 루트에서 에이전트들을 기동 및 관리할 수 있습니다.
+
+### 1) 에이전트 격리 세션 생성 (Create)
+새로운 에이전트를 독립된 격리 가상 디렉토리에서 띄웁니다.
+```bash
+$ bash .agents/skills/multi-agent-mux-create/scripts/create_session.sh \
+    --workspace "/path/to/your/project" \
+    --agent claude \
+    --role developer \
+    --session my-project-dev-claude \
+    --isolate
+```
+*   `--isolate` 옵션을 주면 `.mam/agent_homes/<uuid>/` 하위에 로그인 및 설정은 유지하되 대화 내역은 격리되는 홈이 형성됩니다.
+
+### 2) 세션 접속 (Attach)
+백그라운드에서 구동된 에이전트 TUI 화면에 들어갑니다. (MAM은 독립 격리 tmux 서버인 `-L multi-agent-mux` 를 경유해야 합니다.)
+```bash
+$ tmux -L multi-agent-mux attach -t my-project-dev-claude
+```
+*   **화면 탈출**: 대화 중 세션을 유지한 채 터미널로 돌아오려면 `Ctrl + B`를 누른 뒤 `D` 키를 차례로 입력합니다.
+
+### 3) 에이전트 상태 복원 (Resume)
+세션이 중지되었거나, 호스트 재기동으로 tmux가 소멸한 경우에도 이전 대화 ID 및 격리 디렉토리를 원자적으로 이어받아 다시 기동할 수 있습니다.
+```bash
+# 1단계: resume/SKILL.md를 참고하여 복원 스크립트 실행 (YAML/DB의 UUID 자동 로드 및 T4 격리 재바인딩)
+$ WORKSPACE="/path/to/your/project"
+$ AGENT="claude"
+$ SESSION_NAME="my-project-dev-claude"
+
+$ UUID=$(bash .agents/skills/multi-agent-mux-resume/scripts/resolve_session_id.sh \
+    --workspace "$WORKSPACE" --agent "$AGENT" --session "$SESSION_NAME")
+
+# 2단계: 동적 격리 인자 주입 스폰 수행 후 레지스트리 상태 running 복구
+# (상세 쉘 명령어는 .agents/skills/multi-agent-mux-resume/SKILL.md 참조)
+```
+
+### 4) 세션 종료 및 정리 (Stop / Purge)
+세션을 정지시키고 대화 컨텍스트를 동결하거나(default), 완전히 소멸시킵니다(`--purge-conversation`).
+```bash
+# 대화 메타데이터를 백업 및 영속화하고, 안전하게 종료 (status=stopped)
+$ bash .agents/skills/multi-agent-mux-stop/scripts/stop_session.sh \
+    --session my-project-dev-claude --agent claude
+
+# 대화 내용 및 격리 홈 디렉토리를 완전히 청소하고 종료 (status=terminated, resumable=false)
+$ bash .agents/skills/multi-agent-mux-stop/scripts/stop_session.sh \
+    --session my-project-dev-claude --agent claude --purge-conversation --yes
+```
+
+---
+
+## 🛡️ 협업 및 보안 가이드라인
+*   MAM을 사용할 때 모든 에이전트(개발자, 리뷰어)들은 루트의 `AGENTS.md` 지침을 우선 숙지하도록 설계해야 오탐과 무분별한 리팩토링 범람을 방지할 수 있습니다.
+*   각 에이전트 역할별로 리뷰 프로세스를 돌릴 시, 승인 결과 보고서(.md)는 `.mam/reports/<session_name>/` 하위에 생성 및 형상 커밋하는 규약(`.agents/MULTI_AGENT_RULES.md`)을 준수해 주세요.

+# Review Report (Re-review) — MAM Installer (`scripts/install_mam.sh`) & Manual (`.agents/INSTALL.md`)
+
+- **Reviewer**: Reviewer Cline (`canary-projects-multi-agent-mux-reviewer-cline`, role: reviewer)
+- **Date**: 2026-07-11 (re-review after D1/D2/D3 remediation)
+- **Previous report**: `report-mam-installer-review.md` (verdict: NOT PASS)
+- **Files reviewed**: `scripts/install_mam.sh` (untracked, new), `.agents/INSTALL.md` (untracked, new)
+- **Governing documents**: `AGENTS.md`, `.agents/MULTI_AGENT_RULES.md` / `.ko.md`
+
+---
+
+## Verdict: **PASS** ✅
+
+All three previously-blocking defects (D1 undeclared `rsync` dependency, D2 `__pycache__/`+`.pyc` leak, D3 symlink source mis-resolution) are resolved and verified in-session. The installer now passes `bash -n`, `shellcheck` (clean), a symlink-invocation source-resolution test, an rsync dry-run leak check, and a full end-to-end install into a scratch target. It conforms to `AGENTS.md` and `MULTI_AGENT_RULES.md`.
+
+---
+
+## 1. Remediation Verification (all three defects)
+
+### D1 — `rsync` undeclared dependency → RESOLVED ✅
+**Fix**: `DEPS=(tmux python3 sqlite3 rsync)` (line 80) — `rsync` now in the declared dependency list. `.agents/INSTALL.md` §1 line 14 documents `rsync` as a prerequisite.
+**In-session verification**: Running the installer in a sandbox missing `sqlite3` produced a clean `[ERROR] Missing required dependencies: sqlite3` and exited 1 **before** touching the target — no partial `.agents/` created (post-install checks confirmed `.agents/`, `.gitignore`, and `AGENTS.md` all absent). This proves the D1 fix makes the "Dependency checks completed" gate (line 99) truthful: the script no longer proceeds past the check while a hard dependency is missing.
+
+### D2 — `__pycache__/`+`.pyc` leak → RESOLVED ✅
+**Fix**: rsync invocation (line 107) now includes `--exclude='__pycache__/' --exclude='*.pyc'`.
+**In-session verification**: rsync dry-run with the updated exclude list returned `PycACHE_LEAK_NONE`. Full end-to-end install `find /tmp/.../.agents -name '__pycache__' -o -name '*.pyc'` returned nothing. The target is no longer polluted with host-specific bytecode caches.
+
+### D3 — Symlink source mis-resolution → RESOLVED ✅
+**Fix**: lines 60–67 — a `while [ -h "$SOURCE" ]` readlink loop tracks symlinks back to the original script, with relative-symlink handling (`[[ $SOURCE != /* ]] && SOURCE="$DIR/$SOURCE"`).
+**In-session verification**: I symlinked the installer to `/tmp/mam_install_symlinked.sh` and ran the resolution loop; it resolved `SRC_DIR=/home/godopu16/PuKi/laa/canary_projects/multi-agent-mux` (correct), printing `SYMLINK_RESOLVE_PASS`. The previous failure (resolving to `/`) is gone.
+
+---
+
+## 2. Full Validation Suite (Re-run)
+
+| Check | Command | Result |
+|-------|---------|--------|
+| Syntax | `bash -n scripts/install_mam.sh` | ✅ `BASH_N_OK` |

+| D3 symlink resolve | loop on `/tmp/...symlinked.sh` | ✅ `SRC_DIR=.../multi-agent-mux` (`SYMLINK_RESOLVE_PASS`) |
+| D2 leak dry-run | `rsync --dry-run ... \| grep __pycache__` | ✅ `PycACHE_LEAK_NONE` |
+| D1 dep-gate abort | install with `sqlite3` missing | ✅ clean abort, no partial install |
+| End-to-end install | `install_mam.sh --target /tmp/...` | ✅ completes; `INSTALL_MD_PRESENT`, `GITIGNORE_PRESENT`, `AGENTS_MD_PRESENT`, `PYCACHE_LEAK_CHECK_DONE` (no leaks) |
+| `INSTALL.md` rsync doc | `grep -n rsync .agents/INSTALL.md` | ✅ line 14 documents `rsync` |

+
+---
+
+## Verdict: **NOT PASS** ❌
+
+The script passes its claimed static checks (`bash -n` ✅, `shellcheck` clean ✅) and the manual is well-structured. However, three robustness defects cause the installer to break its own documented success criteria on systems lacking `rsync`, to pollute the target project with host Python bytecode caches, and to mis-resolve its source directory when invoked via symlink. These contradict `AGENTS.md` §4 (Goal-Driven Execution: "Define success criteria. Loop until verified") and §1 (Think Before Coding: "Surface tradeoffs... if unclear, ask"). They are straightforward to fix; this is a *NOT PASS with clear remediation*, not a fundamental design rejection.

+
+## 2. Defects Found (blocking)
+
+### D1 — `rsync` is an undeclared hard dependency (MEDIUM)
+
+**Location**: `scripts/install_mam.sh:100`
+```bash
+rsync -a --exclude='.git/' --exclude='reports/' --exclude='*.log' "$SRC_DIR/.agents/" "$TARGET_DIR/.agents/"
+```
+
+**Problem**: `rsync` is invoked as the core copy mechanism, but it is absent from:
+- The script's `DEPS` array (line 73: `DEPS=(tmux python3 sqlite3)` — no `rsync`)
+- `.agents/INSTALL.md` §1 prerequisite list (tmux, python3, sqlite3, pyyaml — no rsync)
+
+**Impact**: On a system without `rsync` (e.g. minimal containers, some Alpine images, WSL defaults), under `set -euo pipefail` the script aborts at line 100 with an unhelpful `rsync: command not found` — **after** `mkdir -p "$TARGET_DIR/.agents"` (line 96) has already partially created the target tree. The user is left with a half-installed `.agents/` and no guidance from the dependency-check stage (which already printed `[OK] Dependency checks completed.`).
+
+**Why it violates the guidelines**:
+- `AGENTS.md` §4 Goal-Driven: the stated success criterion "Dependency checks completed" (line 92) is *false* when `rsync` is missing — the verification loop is incomplete.
+- `AGENTS.md` §1 Think Before Coding: an undocumented external dependency is exactly the kind of "hidden confusion" the guideline warns against.
+
+**Required fix**:
+```bash
+# Line 73 — add rsync to the declared dependency list
+DEPS=(tmux python3 sqlite3 rsync)
+```
+And mirror in `.agents/INSTALL.md` §1: add `**rsync**: install_mam.sh .agents/ 폴더 동기화에 사용`.
+
+### D2 — `__pycache__/` + `.pyc` bytecode caches leak into the target (MEDIUM)
+
+**Location**: `scripts/install_mam.sh:100`
+
+**Problem**: The rsync exclude list does **not** exclude Python bytecode caches. Dry-run output confirms these files are copied into the target:
+```
+skills/multi-agent-mux-delegate-job/scripts/__pycache__/job_subscriber.cpython-314.pyc
+... (4 .pyc files total)
+```
+
+**Impact**: The installer pollutes the target with host-specific (CPython-version-stamped) bytecode caches. The source repo already ignores these via root `.gitignore` lines 13–14 (`__pycache__/`, `*.pyc`), but rsync reads the filesystem, not gitignore. The target inherits machine-specific artifacts that may confuse later `python3` runs or get accidentally committed.
+
+**Why it violates**: `AGENTS.md` §2 Simplicity First ("No features beyond what was asked") and §3 Surgical Changes (installer should install, not leak build state).
+
+**Required fix**:
+```bash
+rsync -a --exclude='.git/' --exclude='reports/' --exclude='*.log' \
+  --exclude='__pycache__/' --exclude='*.pyc' \
+  "$SRC_DIR/.agents/" "$TARGET_DIR/.agents/"
+### D3 — Symlink-invoked source resolution mis-resolves to `/` (MEDIUM)
+
+**Location**: `scripts/install_mam.sh:60`
+```bash
+SRC_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")/.." && pwd)"
+```
+
+**Problem**: `${BASH_SOURCE[0]}` returns the *invocation path*, not the resolved real path. When the script is run via a symlink (e.g. `ln -sfn .../install_mam.sh /usr/local/bin/mam-install && mam-install`), `dirname "/usr/local/bin/mam-install"` = `/usr/local/bin`, and `cd /usr/local/bin/..` = `/usr/local`. In my test with a `/tmp` symlink, this resolved to `/` — the script would then look for `/.agents/` (wrong/empty source) and either copy the wrong tree or fail with a confusing "source and target identical" or "no such file" error.
+
+**Impact**: The documented usage (`bash scripts/install_mam.sh --target ...`) works only when invoked from a real path. Users who symlink the installer into their `PATH` (a common pattern) get silent wrong-source behavior or an obscure failure, with no diagnostic pointing at the symlink issue.
+
+**Why it violates the guidelines**:
+- `AGENTS.md` §1 Think Before Coding: a silent wrong-source copy is the kind of hidden confusion the guideline exists to prevent.
+- `MULTI_AGENT_RULES.md` path-safety: the rest of the framework uses `readlink`-based resolution and explicit path guards; this installer is inconsistent with that norm.
+
+**Required fix** (Linux; the project's documented platform):
+```bash
+SRC_DIR="$(cd "$(dirname "$(readlink -f "${BASH_SOURCE[0]}")")/.." && pwd)"
+```
+`readlink -f` is GNU coreutils. If macOS support is required, a portable fallback:
+```bash
+src="${BASH_SOURCE[0]}"
+while [ -L "$src" ]; do src="$(readlink "$src")"; done
+SRC_DIR="$(cd "$(dirname "$src")/.." && pwd)"
+```
+Add `readlink` to `DEPS` if taking the `readlink -f` route.
+
+---
+
+## 3. Conformance to `AGENTS.md`
+
+| Principle | Assessment |
+|-----------|------------|
+| §1 Think Before Coding | ❌ D1/D3 hide undocumented dependencies and a symlink footgun instead of surfacing them. |
+| §2 Simplicity First | ⚠️ Mostly clean, but D2 ships unrequested bytecode artifacts — a non-minimal side effect. |
+| §3 Surgical Changes | ✅ No drive-by refactors; existing-user `AGENTS.md` is backed up before overwrite (lines 106–110). |
+| §4 Goal-Driven Execution | ❌ D1: the "Dependency checks completed" success criterion (line 92) is unverified for `rsync`. |
+
+---
+
+## 4. Conformance to `MULTI_AGENT_RULES.md`
+
+| Rule | Assessment |
+|------|------------|
+| `.mam/` under gitignore | ✅ `.gitignore` injection (lines 119–134) is idempotent (`grep -Fqx`), path-safe, scoped to `/.mam/`. |
+| Path safeguards | ⚠️ The `SRC_DIR == TARGET_DIR` self-install guard (line 66) is good, but D3's symlink mis-resolution can still point `SRC_DIR` at an unexpected location, undermining the guard. |
+| Markdown collaboration | ✅ `.agents/INSTALL.md` is a proper markdown manual; this report is persisted under `.mam/reports/<session>/`. |
+| Role isolation | ✅ No cross-role scope creep — this is pure install tooling. |
+
+---
+
+## 5. What's Good (acknowledge correctly done)
+
+- `set -euo pipefail` at the top — correct strict-mode hygiene.
+- `SRC_DIR == TARGET_DIR` self-install guard (line 66) — prevents the script from copying onto itself.
+- `AGENTS.md` backup-before-overwrite with timestamped `.bak.<epoch>` (lines 107–110) — respects existing user files; `--force` is opt-in.
+- `.gitignore` injection is **idempotent** (the `grep -Fqx` check prevents duplicate appends on re-run) and the `grep` non-zero return is safe under `set -e` because it sits in an `if` conditional.
+- `INSTALL.md` is clear, Korean-localized, and correctly documents the `--isolate` flag, the `-L multi-agent-mux` tmux server convention, and the resume/purge state machine.
+- `bash -n` and `shellcheck` claims are **accurate** — I reproduced both.
+
+---
+
+## 6. Remediation Summary (for the developer)
+
+| ID | Fix | Effort |
+|----|-----|--------|
+| D1 | Add `rsync` to `DEPS` array (line 73) and to `INSTALL.md` §1 prereq list | 2 lines |
+| D2 | Add `--exclude='__pycache__/' --exclude='*.pyc'` to the rsync invocation (line 100) | 1 line |
+| D3 | Resolve symlinks: `readlink -f "${BASH_SOURCE[0]}"` before `dirname`/`cd` (line 60); add `readlink` to `DEPS` | 1–2 lines |
+| Re-verify | Re-run `bash -n` + `shellcheck` + a scratch-target dry-run after fixes | — |
+
+All three are small, surgical edits that trace directly to the defects above. No design rework is needed.
+
+---
+
+## 7. Final Statement
+
+The installer's static hygiene is genuine (`bash -n`/`shellcheck` pass as claimed), and the manual is solid. But three robustness defects — an undeclared `rsync` dependency that falsifies the "dependency checks completed" gate, a bytecode-cache leak that pollutes the target, and a symlink source-resolution bug that can silently copy from the wrong directory — mean the installer does not yet meet `AGENTS.md`'s "Goal-Driven Execution" bar (the success criteria are not actually verified) or the "Think Before Coding" bar (hidden failure modes not surfaced). These are fixable in under five lines total.
+
+**NOT PASS** — return to developer with D1/D2/D3 remediation. Re-review after the three fixes are applied and a scratch-target dry-run confirms no `__pycache__/` leak and a symlink-invoked run resolves the correct `SRC_DIR`.

+💡 Quick Start Guide:
+  1. Initialize a new isolated session:
+     $ bash .agents/skills/multi-agent-mux-create/scripts/create_session.sh \\
+         --workspace "$TARGET_DIR" --agent claude --role developer --isolate
+
+  2. Attach to the running session:
+     $ tmux -L multi-agent-mux attach -t <session_name>
+
+  3. Gracefully stop the session:
+     $ bash .agents/skills/multi-agent-mux-stop/scripts/stop_session.sh \\
+         --session <session_name> --agent claude
