## 2. Verification Methodology

1. Gathered changeset via `git diff --stat` and per-file diffs.
2. Verified `.gitmodules` relative URL resolution against the **actual** parent origin
   (`git remote get-url origin` → `https://git.godopu.com/tmpl/multi-agent-mux`) and the
   configured submodule URL in `.git/config` + submodule's own `origin`.
3. Confirmed on-disk existence of every `nats-docker/` path referenced in the docs; confirmed
   no orphaned root-level `PRIVATE_SERVER.md` / `NATS_REPORT.md` / `docker/`.
4. Cross-checked all 10 `MQTT_*` env vars in `MESSAGING.md` §4.4 against
   `mqtt_common.py` (`broker_config_from_env` + `make_client` defaults + docstring).
5. Verified `deploy/gitea-ci.yml` test job enables `submodules: recursive`.
6. Ran mandated tests: `.venv/bin/python -m pytest tests/test_deploy_freshness.py tests/test_sanity.py -q`.
7. Ran D-31/D-32 in isolation.
8. Audited `IMPROVEMENTS.md` section-header structure (`grep '^## '`) against the diff to detect
   insertions that orphan or duplicate existing sections.

## 3. Verification Results

### 3.1 `.gitmodules` relative URL — PASS
- Parent origin: `https://git.godopu.com/tmpl/multi-agent-mux`.
- `../../laa/nats-docker` resolves: `/tmpl/multi-agent-mux` → `../` → `/tmpl` → `../../` →
  host root → `laa/nats-docker` = **`https://git.godopu.com/laa/nats-docker`**.
- Confirmed equal to `git config --get submodule.nats-docker.url` and the submodule's own
  `origin` fetch/push URL.
- Submodule checked out at `a4b6e49` (heads/main). Relative form improves org-wide mirroring
  portability vs the prior absolute URL. No functional regression.

### 3.2 Submodule on-disk asset integrity — PASS
All paths referenced by the docs exist under `nats-docker/`:
- `nats-docker/docker/{docker-compose.yaml, nats.conf, .env.example, README.md}`
- `nats-docker/PRIVATE_SERVER.md`, `nats-docker/NATS_REPORT.md`

No orphaned root-level `PRIVATE_SERVER.md` / `NATS_REPORT.md` / `docker/` remain (confirmed via
`ls`; all three return "No such file or directory"). The `12ba30b` / `629a67f` migration is
complete on disk.

### 3.3 `MESSAGING.md` — PASS
- §1.2 cleanly switched from "Mosquitto/EMQX" to "NATS server (`nats:2.12-alpine`)"; mermaid
  diagram, ACL accounts (`mam_agent` / `mam_observer`), and `nats-docker/docker/nats.conf`
  references are consistent with the submodule assets.
- §4.4 environment table now lists **all 10** supported `MQTT_*` variables.
- `MQTT_CLIENT_ID_PREFIX` default documented as **`hermes`**, matching
  `mqtt_common.py:230` (`os.environ.get("MQTT_CLIENT_ID_PREFIX", "hermes")`) and the
  module docstring (`mqtt_common.py:218`). **Prior finding M-1 is RESOLVED.**
- §4.4 `.mam.env` resolution hierarchy documents B-17 fail-closed behavior (explicit
  `MAM_ENV_FILE` missing → log error + `RuntimeError` at connect; public-broker security
  warning). Consistent with the B-17 action direction recorded in `IMPROVEMENTS.md`.

### 3.4 `MQTT_*` env cross-check vs `mqtt_common.py` — PASS
All 10 documented vars are parsed by code: `MQTT_BROKER`, `MQTT_PORT`, `MQTT_TLS`,
`MQTT_USERNAME`, `MQTT_PASSWORD`, `MQTT_CA_CERTS`, `MQTT_CERTFILE`, `MQTT_KEYFILE`,
`MQTT_CLIENT_ID_PREFIX`, `MQTT_KEEPALIVE`. No drift. D-32 enforces presence of these 10.

### 3.5 `deploy/gitea-ci.yml` — PASS
- `test` job (line 87-89): `actions/checkout@v3` with `submodules: recursive`.
- The job runs `pytest tests/ -q` (line 112) → correctly classified as a test job by D-31.
- `lint-shell` / `lint-python` jobs intentionally omit `submodules` (they do not touch
  `nats-docker/` paths) — D-31's logic only requires submodules on pytest jobs, which is
  the correct, minimal scope.

### 3.6 `implementation_plan.md` — PASS
- Track 1R row updated to cite `nats-docker/PRIVATE_SERVER.md` §9 and
  `nats-docker/docker/docker-compose.yaml` (submodule-prefixed) instead of root-level paths.
- M2b gate annotated with `(290 -> 297 -> 306)`.
- P0.6 checklist block added (submodule split, dynamic path resolvers, CI checkout sync).
- §7 `IMPROVEMENTS.md` description corrected: removed the prior false claim
  "A-2 완료 전환, B-14/B-15/B-16/O-5 해결 상태 갱신" (A-2 is still open) and replaced with
  "B-14/B-15 완료 상태 반영, O-6 신설, B-17/B-18 신설 등록" — factually accurate.

### 3.7 Mandated tests — PASS
- `pytest tests/test_deploy_freshness.py tests/test_sanity.py -q` → **33 passed** in 21.45s.
- D-31 (`test_d31_gitea_ci_submodules_in_test_job`) — PASS in isolation.
- D-32 (`test_d32_messaging_doc_covers_all_mqtt_env_vars`) — PASS in isolation.
- No doc regressions; 100% pass rate confirmed.

### 3.8 Prior-review findings disposition
- **M-1** (MESSAGING.md `MQTT_CLIENT_ID_PREFIX` default mismatch) — **RESOLVED** (now `hermes`).
- **M-2** (IMPROVEMENTS.md open-item count excluded B-18) — **RESOLVED** (now 5건 incl. B-18).
- **L-1** (§6.6 stale conclusion listing B-14/B-15) — **RESOLVED** (now lists B-16/B-17/B-18).
- **L-2** (§3 header count included completed O-6) — **PARTIALLY RESOLVED**: the new §3 (line 56)
  correctly splits "추적 중 1건 / 완료 1건"; however the *old* §3 remains stale (see M-3).

---

## 4. Detailed Findings

### M-3 (Medium) — Duplicate §2 and §3 section headers in `IMPROVEMENTS.md`

- **Location**: `IMPROVEMENTS.md` — new §2 at line 28 and new §3 at line 56; pre-existing §2 now
  at line 120 and §3 at line 143.
- **Observation**: This changeset *inserted* new `## 2.` and `## 3.` sections (with updated
  content: B-14/B-15 marked `✅ 완료`, B-17/B-18 added, O-6 added) immediately after the §1 intro,
  but did **not remove** the pre-existing `## 2.` (Edge-case Bugs) and `## 3.` (Orchestration)
  sections that remain further down. Confirmed via `grep -n '^## '` showing two `## 2.` and two
  `## 3.` headers, and via `git diff` which contains only an insertion hunk (`@@ -23,6 +23,52 @@`)
  with no deletion of the old sections.
- **Contradiction introduced**: the duplicate sections disagree:
  - New §2 (line 30-36): B-14 and B-15 carry `✅ 완료` markers with "조치 결과 (완료 — 커밋 `c6b6c77`)".
  - Old §2 (line 120-141): B-14/B-15 are described as open with "조치 방향 (Track 0 Step 1/2/3)"
    and no completion marker — implying unresolved.
  - New §3 (line 56): header "추적 중 1건 / 완료 1건: O-5, O-6", lists O-5 + O-6 (✅).
  - Old §3 (line 143): header "1건", lists only O-5.
- Additionally, the `A-4` entry (a completed structural-improvement proposal) is now orphaned
  between the new §3 and the old §2 (it originally sat under §1 Architecture).
- **Impact**: Medium. Purely documentation-level (no runtime/test effect; no D-guard asserts
  section-header uniqueness). However it directly undermines the stated goal of this changeset
  ("synchronize documentation"): a reader navigating by section number hits contradictory
  duplicate content, and stale "action direction" text for already-completed B-14/B-15 persists.
- **Recommendation**: Delete the now-redundant old §2 (lines ~120-141) and old §3 (lines ~143-153)
  blocks — the new §2/§3 supersede them. Re-home `A-4` (e.g., into §1 or §5 Completed) so it no
  longer dangles between sections. This is a surgical delete, not a redesign.

### M-4 (Low) — `§5` completed-tasks header count stale

- **Location**: `IMPROVEMENTS.md` line 158 — `## 5. 🎉 완료된 과제 (Completed Tasks — 24건)`.
- **Observation**: The header summary (line 6) was updated to claim **27** completed items
  (adding B-14, B-15, O-6). But the §5 header still reads **24건** and the §5 body was not
  extended to include B-14/B-15/O-6 (those three are instead described inline in the new §2/§3
  with `✅` markers). This creates an internal count drift between the top summary and the §5
  detail section.
- **Impact**: Low. Internal consistency only; not enforced by any D-guard.
- **Recommendation**: Either update §5 header to 27건 and migrate B-14/B-15/O-6 entries into §5,
  or annotate §5 to note the three are tracked in §2/§3. Pick one location as the single source
  of truth for the completed list.

### Note (positive)
- `MESSAGING.md` and `implementation_plan.md` changes are clean, accurate, and well-synchronized
  with the NATS deployment and submodule state. No orphaned root-level files. The `MQTT_*`
  table, broker architecture, ACL/account model, and `.mam.env` resolution hierarchy are all
  consistent with `mqtt_common.py` and the `nats-docker/` assets.
- D-31/D-32 are well-scoped, auto-disable gracefully when prerequisites are absent, and include
  anti-void assertions (they assert at least one test job exists / at least one MQTT var is
  documented).

## 5. Risk Assessment

| Area | Status |
|---|---|
| Runtime behavior | No code change outside tests/docs; behavior unaffected. PASS. |
| Test suite | 33/33 mandated tests pass; D-31/D-32 green in isolation. PASS. |
| Submodule integrity | Relative URL resolves correctly; submodule checked out; assets on disk. PASS. |
| Documentation sync (MESSAGING.md / implementation_plan.md) | Accurate and complete. PASS. |
| Documentation sync (IMPROVEMENTS.md) | New content correct, but duplicate §2/§3 + stale §5 count (M-3/M-4). Minor. |
| Loss / orphaned references | None — all `nats-docker/` doc links resolve; root-level originals removed. PASS. |

All findings (M-3, M-4) are documentation-level, non-blocking, and fixable by surgical edits.
No design-level rework is warranted; no `[ESCALATE: PLANNER]` is required.

---

## 6. Actionable Follow-ups (optional, separate cleanup commit)

1. **M-3**: Remove the duplicate old §2 (lines ~120-141) and old §3 (lines ~143-153) blocks in
   `IMPROVEMENTS.md`; re-home the orphaned `A-4` entry.
2. **M-4**: Align `§5` header count (24건) with the summary (27건), or annotate §5 to delegate
   B-14/B-15/O-6 to §2/§3.

---

## 7. Verdict

All mandated tests pass, the `.gitmodules` relative URL resolves correctly, submodule assets
are intact, `MESSAGING.md` and `implementation_plan.md` are accurately synchronized with the
NATS deployment, and the prior review's M-1/M-2/L-1 findings are resolved. The two new findings
(M-3 duplicate §2/§3 headers, M-4 stale §5 count) are documentation-level, non-blocking, and
do not affect runtime behavior or test results. No escalation to the planner is warranted.

[VERDICT: PASS]
