Source: 62-agent adversarial audit (2026-07-16) + skill `iot-airgap-delivery` §3 + manual
verification of every blocker against real code. Ordered for sequential fixing. Each item is
checked off only after a test locks it and verification passes.

Legend: **[B]** blocks delivery · **[H]** high · **[M]** medium · **[L]** low ·
`OFF-HW` = cannot be verified without the Hailo board.

---

## Phase 1 — Silent failure & misconfiguration (the #1 delivery risk)

A safety system that *looks* healthy while doing nothing is the worst failure. Make every
misconfig/degradation fail LOUD.

- [x] **P1-1 [H]** `edge/serverclient.py`, `edge/alert.py` — `requests` sends the default
  `python-requests/x.y` User-Agent; cafe24's shared-hosting WAF commonly blocks it with an
  HTML 403 while curl passes. Every event then silently fails. Also `allow_redirects=True`
  turns the .htaccess http→https 302 into a GET → 405/404. **Fix:** custom UA
  (`move-detect-edge/1.0`) on every call + `allow_redirects=False`, log once on 3xx.
  DONE — `USER_AGENT` in alert.py, both clients send it + `allow_redirects=False`;
  tests in test_alert.py / test_serverclient.py.
- [x] **P1-2 [B]** `deploy/systemd/move-detect-edge.env.example`, `setup_online.sh` prompt,
  docs — `CAFE24_URL` must be `https://<domain>/move_detect` (subdir mount). Empty/typo/
  missing-subdir is 100% silent. **Fix:** examples show the subdir; installer validates.
  DONE — env.example + installer prompt now show/require the `/move_detect` subdir.
- [x] **P1-3 [H]** `edge/config.py:40` + `edge/daemon.py` — empty `CAFE24_URL`/`DEVICE_SECRET`
  defaults let the daemon run green while every upload fails and the queue grows forever.
  **Fix:** fail loud at startup if either is blank.
  DONE — `require_upload_config(cfg)` raises at daemon startup; test_config.py locks it.
- [x] **P1-4 [H]** `edge/daemon.py:23` — `run_loop` swallows every per-frame/per-camera
  exception with no log and no degraded-monitoring signal → a permanently broken pipeline
  looks green. **Fix:** rate-limited `logging.exception` + consecutive-error counter.
  DONE — per-camera + periodic error streaks, logged 1st + every 300th, names the camera;
  test_daemon.py locks the rate-limit.
- [x] **P1-5 [H]** `edge/daemon.py:33` — heartbeat hardcodes `fps=0.0` and counts ticks where
  `source.read()` returned nothing, so the server cannot tell a dead device from a live one.
  **Fix:** real fps + per-camera frame-age/health in the heartbeat body.
  DONE — heartbeat now sends measured fps + cameras_total/cameras_erroring/errors;
  test_daemon.py locks fps math + failing-camera flag.
- [x] **P1-6 [H]** `edge/adapters/uvc_source.py:12` — a camera that stops delivering frames is
  never detected or reopened; monitoring dies silently. **Fix:** fail loud on open failure;
  emit `device_fault`/`monitoring_degraded` when a camera goes stale.
  DONE — open-failure raises (build_runtimes logs+skips); read() releases+reopens after a
  streak; heartbeat's cameras_erroring (P1-5) reports the fault. test_uvc_source.py locks it.
- [x] **P1-7 [M]** `edge/queue.py` — offline sqlite queue has no size cap/TTL; an outage (or a
  permanent misconfig) fills the SD card, then new events drop silently. **Fix:** bounded
  queue (row/byte budget), log dropped-oldest count.
  DONE — `max_rows` (default 2000) evicts oldest on enqueue; test_queue.py locks it.
- [x] **P1-8 [H]** `edge/queue.py:52` — a permanently-rejected event (e.g. 400) is retried
  forever at the head, blocking the whole queue. **Fix:** drop/quarantine after N failures.
  DONE — `attempts` column; a row is dropped after `max_send_attempts` (default 20) so a
  poison head unwedges the queue; test locks the drain-past-poison behavior.
- [x] **P1-9 [M]** `edge/alert.py:43` — a POST that succeeds server-side but times out
  client-side is re-queued and re-sent; no dedup key → duplicate alerts. **Fix:** stable
  client-generated `event_id` in the payload; server dedups on it.
  DONE — the edge `Event` now carries a stable `event_uuid` (uuid4 hex, generated once at
  creation, preserved through the offline queue + every retry). Server: `events.event_uuid`
  CHAR(32) NULL UNIQUE; `EventValidator` accepts/validates it; `IngestController` returns the
  already-stored event (200 `dedup:true`) on a repeat uuid, race-safe against the UNIQUE key.
  Tests: queue round-trip keeps the uuid (edge); repeat-uuid dedups to one row (server).
- [x] **P1-10 [M]** `edge/daemon.py:134` — `TARGET_FPS=0`/non-numeric → ZeroDivision/ValueError
  at every start → infinite systemd restart loop. **Fix:** validate, default sanely.
  DONE — `frame_interval_from_env` validates; test_config.py locks it.
- [x] **P1-11 [L]** `edge/daemon.py:120` — `QUEUE_DB` defaults to relative `queue.db`,
  unwritable under the hardened unit (`ProtectSystem=strict`) → crash loop when env omitted.
  **Fix:** absolute default under the state dir.
  DONE — `queue_db_path` defaults to /var/lib/move-detect/queue.db; test_config.py locks it.

## Phase 2 — Core safety correctness (fall / zone / tracking)

- [x] **P2-1 [B]** `edge/zones.py:19` ↔ `server/public/assets/zone-draw.js:196` — zones are
  saved in 960×540 canvas pixels but the edge compares against camera-native pixels; **every
  zone is silently misplaced.** **Fix:** normalized 0..1 polygon contract on both sides.
  DONE — dashboard stores/loads 0..1 (zone-draw.js), edge normalizes the foot by frame size
  (zone.py → engine.process → run_once threads frame_wh); Polygon::validate is range-agnostic
  so PHP stores it opaquely. test_zone.py locks the normalized contract.
- [x] **P2-2 [B]** `edge/engine.py:72` — a `pinch` (협착) zone falls through to
  `ZONE_WARNING`; the PINCH event + HIGH severity are never emitted. **Fix:** map
  `pinch→PINCH`, `restricted→ZONE_RESTRICTED`, else WARNING.
  DONE — dict map pinch→PINCH/restricted→ZONE_RESTRICTED; test_engine.py locks PINCH+HIGH.
- [x] **P2-3 [H]** `edge/detectors/fall.py:65` — a per-frame keypoint-confidence gate
  silently disables fall, no_motion AND ghost for an occluded/low-confidence fallen person —
  exactly when someone is on the floor. **Fix:** use bbox cues when keypoints are low-conf.
  DONE — bbox cues (aspect/height-collapse) always run; keypoint cues gated by kp_ok;
  test_fall.py locks both the low-conf detection and the no-false-positive-standing case.
- [x] **P2-4 [H]** `edge/detectors/ghost.py:38` — a ghost candidate is cancelled when ANY
  person (a colleague) passes near the loss point. **Fix:** only the plausibly-same track
  cancels it.
  DONE — candidate snapshots the active track ids at loss time; only a NEW track (not a
  known bystander) near the loss point cancels. test_ghost.py locks the bystander case.
- [x] **P2-5 [H]** `edge/geometry.py:66` — stillness compares raw per-frame displacement to a
  fixed threshold with no dt normalization → immobility/no_motion flips with FPS. **Fix:**
  normalize by elapsed time.
  DONE — track_displacement divides by dt (per-second speed); test_geometry.py locks
  FPS-invariance. NOTE: motion_thr is now per-second and needs on-device re-tuning.
- [x] **P2-6 [M]** `edge/tracking.py:50` — greedy IoU matching swaps IDs when workers cross,
  transferring FALLEN state + frozen baseline to the wrong person. **Fix:** gate matches;
  reset per-track safety state on a low-confidence match.
  DONE — global greedy (all pairs sorted by IoU desc) replaces track-order greedy; any track
  in a contended match (person↔2 tracks or track↔2 persons) is reported via
  `tracker.ambiguous()` and run_once resets its engine + smoother state. A still-prone worker
  re-confirms within prone_confirm_s. test_tracking.py + test_app.py lock both.
- [x] **P2-7 [M]** `edge/detectors/fall.py:92` — a single prone-looking frame sets FALLING and
  arms a CRITICAL ghost if the person then leaves. **Fix:** require sustained prone.
  DONE — STANDING→FALLING now requires sustained prone (`falling_confirm_s`, default 1.0s,
  dataclass-only, no env knob). FALLEN/no_motion timing unchanged (keyed off prone_since).
  test_fall.py locks it.
- [x] **P2-8 [M]** `edge/app.py:30` — detection dropouts keep a track 'active' with a frozen
  frame; time-based timers accrue on stale data. **Fix:** treat a stale track as no-data.
  DONE — run_once feeds the engine (and smoothers) only tracks re-detected THIS tick
  (`latest.t == now`); a stale track is no-data until re-detected or lost. Re-detection still
  confirms the fall (dropout pauses evidence, doesn't erase it). test_app.py locks both.
- [x] **P2-9 [M]** `edge/detectors/zone.py:45` — foot point averages both ankles with no
  confidence check; a hallucinated ankle at (0,0) drags the foot into/out of a zone. **Fix:**
  confidence-gate the ankles, fall back to bbox-bottom-center.
  DONE — `_foot` averages only ankles with conf ≥ MIN_ANKLE_CONF (0.2, the existing 'visible'
  gate); with neither trustworthy it falls back to bbox bottom-centre. No tuning knob — reuses
  the codebase's keypoint-visible convention. test_zone.py locks the fallback.
- [x] **P2-10 [M]** `edge/adapters/movenet_pose.py:34` — the CPU MoveNet fallback is
  single-person; with 2+ workers all but one are invisible to every detector, no warning.
  **Fix:** warn loudly that MoveNet fallback is single-person (Hailo is multi-person).
  DONE — MoveNetPoseAdapter.__init__ logs a startup WARNING ("SINGLE-PERSON … use POSE_BACKEND=
  hailo at multi-person sites"). test_movenet_pose.py asserts the warning via caplog.
- [x] **P2-11 [L]** `edge/geometry.py:39` — `head_below_hips` uses the NOSE keypoint
  regardless of confidence. **Fix:** confidence-gate.
  DONE — `head_below_hips` returns False when nose conf < nose_thr (0.2), so an unconfident/
  hallucinated nose no longer fires the fall cue. test_geometry.py locks it; test_fall.py stays
  green (the cue's confident-nose path is unchanged).

## Phase 3 — Privacy / PIPA (delivery compliance)

- [x] **P3-1 [H]** `edge/app.py:18` — `FaceBlurrer` blurs a fixed ~40×40px patch regardless of
  face size; close faces stay identifiable. **Fix:** size the blur box from the person bbox.
  DONE — `_head_boxes` sizes the box from the person bbox (scales with distance) + bbox-top
  fallback when the nose keypoint is low-confidence. test_faceblur.py locks both.
- [x] **P3-2 [H]** `server/src/Ingest/IngestController.php:68` — worker snapshots are stored
  forever; no retention/purge anywhere. PIPA violation. **Fix:** `snapshot_retention_days`
  config + a token-guarded purge route + `SnapshotRepository::purgeOlderThan`.
  DONE (retention = **7 days**) — `snapshot_retention_days` config; `purgeOlderThan` on the
  interface + Pdo + double (files then rows, bounded batch); opportunistic purge in the
  ingest path (cafe24 has no cron; the edge POSTs 24/7). IngestControllerTest locks it.
- [x] **P3-2b [M]** `server/src/Dashboard/EventListController.php:17` — `site_scope` is stored
  in the session but never enforced; any authenticated user sees every device's worker
  snapshots. **Fix:** scope event/snapshot queries by the session's `site_scope`.
  DONE (site↔device model approved) — added `devices.site`; ingest denormalizes it onto
  `events.site` (server-derived, never client-supplied). `App\Security\SiteScope` centralizes the
  rule (NULL scope = global operator). The event LIST filters in SQL (`page(...,$site)`); event
  DETAIL + ACK and the SNAPSHOT proxy guard per-row and return 404 (not 403) cross-site so
  existence never leaks. Migration ALTERs + provisioning UPDATEs documented in schema.sql.
  Tests: list scoped, detail cross-site 404, snapshot cross-site 404 / same-site 200.
- [x] **P3-3 [H]** `edge/tools/fetch_movenet.py:12` — downloads the ONNX from a mutable ref
  with no checksum; spec mandates SHA256. **Fix:** pin URL to a commit + sha256+size, mirror
  `fetch_hailo_hef.py`.
  DONE (with a caveat) — rewrote to stage-validate: rejects HTML/LFS-pointer, optional pinned
  sha256+size, temp-file staging, fails LOUD. DISCOVERY: the old URL is DEAD (GitHub 404 / HTML
  — PINTO hosts models off-repo), so it was silently saving garbage. No known-good sha256 to
  pin until a valid MOVENET_ONNX_URL is set. NON-BLOCKING for the Hailo delivery path (MoveNet
  is the optional CPU fallback); flag for whoever needs CPU MoveNet.

## Phase 4 — Server hardening (shared hosting)

- [x] **P4-1 [H]** `server/public/index.php:106` — no top-level try/catch; a PDOException
  becomes a raw 500 that leaks DSN/db_user if `display_errors` is on (cafe24 often ships On).
  **Fix:** global try/catch → generic 500 + `error_log`; `ini_set('display_errors','0')`;
  ship `.user.ini`.
  DONE — index.php sets display_errors=0 + a set_exception_handler → generic {"error":"internal"}
  + error_log; a `.user.ini` (display_errors=Off) ships in www/move_detect/ as the pre-parse
  backstop. Package build verified.
- [x] **P4-2 [H]** `server/src/Api/ConfigController.php:22`, `HeartbeatController.php` — no rate
  limiting (unlike /api/events). **Fix:** per-IP + per-device limiter, fail-open on storage
  error.
  DONE — both take an optional RateLimiterRepository + clientIp; pre-auth per-IP limit
  (shared ingest_ip cap) returns 429; index.php passes REMOTE_ADDR. ApiSyncTest locks the flood.
- [x] **P4-3 [M]** `server/src/Repository/Pdo/PdoNonceRepository.php:30` — nonces + rate_limits
  grow without bound; no cron on cafe24. **Fix:** opportunistic in-request reap of expired
  rows.
  DONE — remember() reaps expired nonces; hit() reaps stale rate-limit windows (bounded,
  gated 1/100). Full PHP suite green.
- [x] **P4-4 [M]** `server/src/Http/Router.php:18` — route params are never `rawurldecode`d; a
  `camera_id` with a space/`+`/Korean saves zones but never loads them. **Fix:** decode
  captured params.
  DONE — dispatch rawurldecodes captured params; BasePathTest locks space + Korean cases.
- [x] **P4-5 [M]** `server/src/Dashboard/EventListController.php:17` — event list hard-capped at
  newest 100, no pagination/date filter; older events unreachable. **Fix:** cursor pagination.
  DONE — added keyset `EventRepository::page(limit, severity, beforeTs, beforeId)` (Pdo + InMemory),
  a `(occurred_at DESC, event_id DESC)` cursor stable under concurrent inserts. Controller takes
  `limit` (default 50, cap 200) + `cursor` ("occurred_at:event_id"), returns `next_cursor` on full
  pages. `recent()` kept for existing callers. The live-tail dashboard consumes page 1; a
  history-browse UI can layer on the same cursor later. Test `testListPaginatesWithCursor`.
- [x] **P4-6 [M]** `server/src/Repository/Pdo/PdoZoneRepository.php:86` — editing a zone with a
  changed device_id/camera_id throws an uncaught RuntimeException → 500. **Fix:** 400 with a
  clear error.
  DONE — ZoneConfigController::save wraps `$this->zones->save()` in try/catch(\RuntimeException)
  → `invalid_zone` 400; test `testSaveOwnershipMismatchIs400NotError` with a throwing repo double.
- [x] **P4-7 [L]** `server/src/Ingest/IngestController.php:64` — snapshot write failure is
  swallowed (201 with evidence lost); file-write/DB-insert non-atomic → orphan JPEGs. **Fix:**
  order write→insert, log failures, reconcile orphans.
  DONE — extracted `storeSnapshot()`: re-encode→write→index in order; every failure (re-encode,
  file write, DB index) now `error_log`s instead of a silent `continue`; a DB-index failure after
  the file lands `@unlink`s the orphan. A snapshot problem no longer fails the ingest — the event
  is already stored, 201 stands. Test `testSnapshotIndexFailureCleansOrphanFileButKeepsEvent`
  (throwing repo double → asserts 201, event stored, no leftover *.jpg).
- [x] **P4-8 [L]** `server/src/Auth/AuthController.php:31` — login form emits a CSRF token that
  `login` never checks. **Fix:** verify it (or drop it).
  DONE — verified (completed the half-built defense, not dropped). login() checks
  `Csrf::check($sess->get('csrf'), $req->post('csrf'))` → 403 before the user lookup, closing the
  login-CSRF / session-fixation hole. Tests updated to seed the session+body token; added
  `testLoginRejectsMissingOrWrongCsrf`.
- [x] **P4-9 [L]** `server/src/Auth/AuthController.php:71` — logout calls `regenerate()` after
  `session_destroy()` → E_WARNING, old cookie not replaced. **Fix:** reorder.
  DONE — logout() rotates the id then wipes (was regenerate-after-destroy).
- [x] **P4-10 [L]** `server/src/Ingest/EventValidator.php:26` — no string length caps → an
  overlong id becomes a MySQL 'Data too long' 500 retry loop instead of a 400. **Fix:** cap
  lengths in the validator.
  DONE — EventValidator caps device_id/camera_id (64) + zone_id (32); EventValidatorTest.
- [x] **P4-11 [L]** `server/src/Http/Request.php:45` — `pathFor` routes any `//...` URI to `/`
  (parse_url scheme-relative). **Fix:** collapse/normalize.

## Phase 5 — Install / bundle / supply-chain

  DONE — pathFor collapses leading slashes before parse_url; BasePathTest locks it.
- [x] **P5-1 [B]** `deploy/bundle/install_offline.sh:79` — the OFFLINE installer has no
  backend-usability gate (setup_online's [6/8] does): it installs `POSE_BACKEND=movenet`
  verbatim even when the bundle carries no working backend. **Fix:** mirror the [6/8] probe.
  DONE — [5/6] probes HEF+hailo_platform / onnx+onnxruntime, reconciles POSE_BACKEND in the
  installed env, hard-fails if neither. test_deploy_artifacts.py locks the gate.
- [x] **P5-2 [H]** `deploy/bundle/build_offline_bundle.sh:55` — a native build on x86 produces
  an aarch64-named tarball full of x86_64 wheels. **Fix:** assert `uname -m == TARGET_ARCH`.
  DONE — native branch now hard-fails when uname -m != TARGET_ARCH.
- [x] **P5-3 [M]** `deploy/bundle/build_offline_bundle.sh:65` — the air-gapped bundle never
  carries the Hailo HEF, so offline Hailo install is impossible. **Fix:** stage the HEF (via
  `fetch_hailo_hef --arch`) into the bundle.
  DONE — build now fetches the `$HAILO_ARCH` (default hailo8) HEF via `fetch_hailo_hef` (pinned
  sha256, aborts on mismatch) and stages `yolov8s_pose.hef`. Also fixed two latent breaks that
  made the offline path unusable regardless: the MoveNet ONNX fetch was unconditional so its dead
  source aborted the whole build under `set -e` (now guarded/optional → Hailo-only bundle), and
  `install_offline.sh` copied only `*.onnx` so a bundled HEF never reached `$PREFIX/models` for the
  backend gate to find (now copies `*.hef` too). MANIFEST lists models + available pose_backends.
  Tests: fetches/stages HEF, MoveNet optional, installer copies the HEF.
- [x] **P5-4 [M]** `deploy/bundle/build_offline_bundle.sh:28` — pip deps unpinned, no digests,
  MANIFEST has no hashes, bundle unsigned; spec requires SHA256/GPG + SBOM. **Fix:** pin +
  hash + manifest digests.
  DONE — build emits `SHA256SUMS` (sha256 of every wheel + model), `requirements.lock` (exact
  `name==version` pins for a reproducible rebuild), and `sbom.json` (CycloneDX 1.5: name, version,
  pypi purl, sha256). Optional detached GPG signature via `SIGN_KEY` → `SHA256SUMS.asc`.
  `install_offline.sh` runs `sha256sum -c SHA256SUMS` (and verifies the signature if present)
  BEFORE any pip install, hard-failing on mismatch. Generation logic verified end-to-end on a
  synthetic stage (valid JSON, `sha256sum -c` passes). Tests lock the manifest + the install-time
  check.
- [x] **P5-5 [H]** `deploy/systemd/move-detect-edge.service:46` `OFF-HW` — `DeviceAllow` omits
  `/dev/media*` and `/dev/dma_heap`; picamera2/libcamera on Pi 5 needs them, so the CSI camera
  is denied by the unit's own policy. **Fix:** add the device classes; verify on hardware.
  DONE — added `char-media` + `/dev/dma_heap/`. OFF-HW: confirm on the Pi with the CSI camera.
- [x] **P5-6 [L]** `server/deploy/build_cafe24_package.sh` — dev cache dirs
  (`.impeccable/`, `.ruff_cache/`) can ship inside the web-served package. **Fix:** exclude.

---

## Phase 6 — 재감사 2026-08-18 (안전 플랫폼 확장 표면)

커밋 `e00ad69` 로 감사 표면이 크게 늘었다: 신규 라우트 17개, DB 표 6종 + 컬럼 4종, CLI 도구
5개, 엣지 모듈 4개(GPIO 출력 포함), 통보 발송 경로(메일·웹훅) 신설, 감사로그 해시체인.
8개 관점(보안·데이터 정합·렌더·패키징·문서 정합·성능·UX·회귀)으로 재감사, 확정 12건 전량 해소.

### CRITICAL

- [x] **A1 [B]** `server/src/Ingest/EventValidator.php` — 신규 감지 유형(`camera_moved`,
  `camera_obstructed`, `low_light`)이 ingest 허용 목록에 없어 **서버가 전부 400 으로 거부**했다.
  `edge/queue.py` 는 20회 재시도 후 그 행을 버리므로, 카메라 무결성 감지는 구현·테스트·배포가
  전부 끝난 상태로 end-to-end 무력화되어 있었다 — 로그를 뒤지지 않는 한 아무도 모른다.
  DB CHECK 와 프런트 라벨은 갱신했는데 **가운데 검증 계층만** 빠진, 계층 간 목록 중복의 전형적 결함.
  DONE — 허용 목록 갱신 + **언어 경계를 넘는 회귀 테스트** 신설
  (`tests/test_event_type_parity.py`: `edge/events.py` ↔ EventValidator ↔ schema.sql ↔
  프런트 라벨 5종 ↔ 유형 필터). 파이썬·PHP 어느 쪽 테스트도 잡을 수 없던 자리다.
- [x] **A2 [B]** `server/tools/seed_demo.php` — `--purge` 가 위험성평가를
  `reviewed_by='안전관리자' AND site='factory-a'` 로 지웠다. '안전관리자'는 이 제품의 **기본
  관리자 계정명**이고 'factory-a'는 흔한 현장명이라, 운영 DB 에서 한 번 실행하면 실제
  위험성평가가 복구 불가능하게 사라진다.
  DONE — 데모 행은 `DEMO_PREFIX`/`DEMO_ACTOR`/`DEMO_LABEL` 표식으로만 식별. 표식 없는 행은
  어떤 경우에도 건드리지 않는다.
- [x] **A3 [B]** `server/tools/backup.php` — 웹 공개 경로 차단이 `str_contains($real, '/www/')`
  라 **docroot 자체**(`/home/acct/www`)는 뒤에 슬래시가 없어 통과했다. 가장 흔한 오사용이
  정확히 그 경우다. 전 현장의 사고 기록 + 작업자 이미지가 웹에서 내려받힌다 (파일명은
  `move_detect-YYYYmmdd-HHMMSS.sql` 로 하루 범위만 알면 추측 가능).
  DONE — 경로를 세그먼트로 쪼개 `www/public_html/htdocs/html/web/public` 중 하나라도 있으면 거부.
  회귀 검증: docroot 자체·하위 경로 모두 차단, 비공개 경로는 통과.

### HIGH

- [x] **A4 [H]** 신규 유형이 `app.js`/`detail.js`/`report.js` 의 `TYPE_LABELS` 와 이벤트 유형
  필터에 없어 화면에 `camera_moved` 같은 원시 코드가 그대로 표시됐다. 조사자가 그 유형만
  걸러 볼 방법도 없었다. DONE — 3개 맵 + 필터 갱신, A1 의 파리티 테스트가 재발을 막는다.
- [x] **A5 [H]** 서버가 `date_default_timezone_set` 를 하지 않아 통보 메일의 시각이 PHP 기본
  (공유호스팅은 흔히 UTC)으로 찍혔다. 대시보드는 브라우저 시각을 쓰므로, 콘솔이 13:01 로
  보여준 넘어짐을 메일이 04:01 로 적는다 — 응급 대응에서 읽는 유일한 문장이 9시간 어긋난다.
  DONE — `Config::timezone()` (기본 `Asia/Seoul`, 잘못된 값이면 폴백하되 발송은 막지 않음),
  `Channels` 가 프로세스 전역 기본값을 건드리지 않고 해당 시간대로 렌더.
- [x] **A6 [H]** 마이그레이션의 `ALTER TABLE … DROP CHECK` 는 MySQL 8.0.16+ 전용 문법이다.
  카페24 공유호스팅에 흔한 **MariaDB 는 `DROP CONSTRAINT` 를 쓰므로 마이그레이션이 통째로 실패**한다.
  DONE — 해당 블록에 엔진별 분기(A: MySQL 8.0.16+ / B: MariaDB / C: 제약 없음) 를 명시하고,
  이 CHECK 가 2차 방어선이며 1차는 `EventValidator` 임을 적어 실패해도 판단할 수 있게 함.
  적용 확인용 probe INSERT/DELETE 도 함께 기재.

### MEDIUM

- [x] **A7 [M]** `AlertDispatcher::run` 이 매분 창 전체를 다시 훑으며 이미 보낸
  (event, channel) 쌍마다 실패할 INSERT 를 한 번씩 재시도했다. 비용이 '새 이벤트'가 아니라
  '창 길이'에 비례해, 크론이 불안정해 창을 넓힌 현장일수록 부하가 커진다.
  DONE — `claimedSince()` 로 창의 원장을 한 번에 읽어 사전 필터. `claim()` 은 여전히 최종
  권위(경합 시)다. 회귀 테스트가 2·3회차 실행에서 claim 시도가 0 임을 고정.
- [x] **A8 [M]** `move_alert_log` 에 보존 정책이 없어 유일하게 무한 증가하는 표였다
  (이벤트 보존은 기본 비활성이라 CASCADE 도 일어나지 않는다).
  DONE — `maintain.php` 가 해소된 전달(sent/suppressed)만 정리. **failed 는 남긴다** —
  "아무에게도 닿지 않았다"는 사실이 조사에서 필요한 발견이라 청소가 지우면 안 된다.
- [x] **A9 [M]** 전역 관리자가 현장 채널을 수정하면 `site` 가 NULL 로 덮여 그 채널이 **모든
  현장에 발화**하게 됐다. 폼 어디에도 그런 안내가 없다.
  DONE — 수정 시 기존 site 보존, 신규 생성만 호출자 스코프. 양쪽 회귀 테스트 추가.
- [x] **A10 [M]** 일괄 확인이 대상마다 fetch 를 하나씩 띄웠다. 7건에서는 무해하지만 실제
  백로그는 수백 건이고, HTTP/2 에서는 브라우저가 직렬화하지 않아 공유호스팅에 한꺼번에 떨어진다.
  DONE — 동시 4개로 제한하고 진행 중에도 목록을 갱신(멈춘 것처럼 보이지 않게), 완료 토스트에
  `성공/전체` 를 함께 표기.

### LOW

- [x] **A11 [L]** 패키지 테스트가 `tools/` 배치를 검사하지 않았다. 이 도구들은 메일을 보내고
  DB 전체를 읽으므로 www/ 아래로 새면 인증 없는 표면이 된다.
  DONE — ① 모든 CLI 도구가 `bootstrap.php`(SAPI 가드)를 require 하는지 ② 패키지에서 tools/ 가
  private 폴더에만 있는지 ③ 웹 루트의 PHP 가 `index.php`/`_preflight.php` 뿐인지 검사.
- [x] **A12 [L]** 감사 리포트 판정 배너와 `CLAUDE.md` 의 "43/43" 표기가 stale.
  DONE — 이 문서 상단 배너 + CLAUDE.md 갱신.

### 재감사에서 확인만 하고 수정하지 않은 항목 (판단 기록)

- **웹훅 SSRF (내부망 주소 지정 가능)** — 채널 등록은 admin 전용이고, 이 기능의 정당한
  용도가 바로 **사내망** 그룹웨어·문자게이트웨이다. 사설 IP 대역을 막으면 기능 자체가
  성립하지 않는다. http(s) 한정 + 리다이렉트 금지 + 토큰 헤더까지가 방어선. 수용.
- **서버가 엣지 GPIO 핀 번호를 지정** — 손상된 서버가 임의 핀을 구동할 수 있다. 다만 서버는
  이미 존(감지 판정 자체)을 내려보내는 신뢰 주체이고, 핀 범위는 서버측에서 0~40 으로 검증된다.
  이 신뢰 경계를 좁히려면 장치측 화이트리스트가 필요 — 실장비 커미셔닝 항목으로 이관.
- **`/setup` 4단계가 첫 카메라의 존만 확인** — 다른 카메라에 존이 있어도 "없음"으로 보일 수
  있다. 상태 문구에 "첫 카메라에" 를 명시해 오해를 줄였고, 전 카메라 조회는 온보딩 화면이
  N+1 요청을 내는 대가가 이득보다 크다고 판단. 수용.

## OFF-HW 잔여 (실장비 커미셔닝에서만 검증 가능)

코드·문서로 닫을 수 없는 항목. 납품 판정을 막지 않되, 현장 설치 시 반드시 수행한다.

- [ ] **GPIO 경광등 실동작** — `edge/beacon.py` 의 핀 구동은 단위 테스트로 증명할 수 없다.
  Pi + 릴레이 모듈로 latch/pulse, `active_high` 반전, hold 만료 해제를 육안 확인.
- [ ] **카메라 무결성 임계값** — `IntegrityConfig.moved_mad` / `obstructed_var` /
  `low_light_mean` 은 실제 현장 조명·진동에서 튜닝해야 한다. 현재 값은 합성 프레임 기준.
- [ ] **P2-6/7/8** — 낙상 타이밍·트래킹 매칭 (1차 감사에서 이월). 블라인드 수정은 감지 **누락**을
  만들 수 있어 실영상 확보 후 조정.
- [ ] **CSI 카메라 / Hailo HEF 추론** — `tests/hardware/` 스킵 항목.
- [ ] **통보 실발송** — 사내 SMTP 릴레이·웹훅 엔드포인트는 현장에만 있다.
  `dispatch_alerts.php --dry-run` 으로 대상만 먼저 확인한 뒤 1회 실발송 검증.

## Progress log

(updated as each item lands — newest first)

- **2026-07-17 — P1-9 + P3-2b landed (both approved data-model changes).** 40/43 done.
  P1-9: edge `event_uuid` idempotency key (stable through the queue) + server dedup on a UNIQUE
  column. P3-2b: `devices.site` → denormalized `events.site`; `SiteScope` enforced on the event
  list (SQL filter), event detail/ack, and snapshot proxy (per-row 404). Schema migration +
  provisioning UPDATEs documented in schema.sql. phpunit 97, pytest 158 — all green. REMAINING 3:
  P2-6/7/8 (safety-timing / tracking-match — deferred to on-hardware commissioning).

- **2026-07-17 — off-hardware solo work COMPLETE (35/43).** Landed this pass, each test-locked:
  P4-8 (login CSRF), P4-6 (zone 400-not-500), P4-5 (cursor pagination), P4-7 (snapshot atomicity
  + orphan cleanup), P5-3 (HEF in the offline bundle + fixed the broken build), P5-4 (pin + hash +
  SBOM + install-time verify), P2-9/10/11 (keypoint confidence gating + MoveNet single-person
  warning). phpunit 90, pytest 157 — all green.
  REMAINING 8, none solo-doable:
  · P1-9, P3-2b — need a DATA-MODEL decision (event dedup key + schema column; site↔device model).
  · P2-6, P2-7, P2-8 — safety-timing / tracking-match logic that must be validated ON HARDWARE.
    Changing them blind could make fall detection MISS events (worse than today's over-alarm,
    which is fail-safe), so they are deliberately deferred to on-device commissioning.
  · (P2 threshold notes: motion_thr and the sustained-prone/staleness windows are commissioning
    knobs — tune with real camera footage on the Pi.)

- **2026-07-17 — P4-6 + P4-8 landed (server error/auth hardening).** ZoneConfig ownership-mismatch
  now 400 not 500 (P4-6); login CSRF token now verified — closes login-CSRF/session-fixation
  (P4-8). phpunit 88 green (4 skipped: PDO). Remaining solo: P4-5 (pagination), P4-7 (atomic
  snapshot), P5-3 (HEF in bundle), P5-4 (pin+hash+SBOM).

- **2026-07-17 — 17 items landed, all with tests, full suite green.** ALL 4 BLOCKERS cleared
  (P1-2, P2-1, P2-2, P5-1) + all Phase-1 silent-failure (P1-1,3,4,5,6,7,8,10,11) + Phase-2 HIGH
  correctness (P2-3,4,5). Remaining: P1-9 (deferred to server batch), P2-6..11 (mostly threshold
  tuning — needs on-device validation), Phase 3 (privacy — P3-2 retention needs a policy
  decision: how many days), Phase 4 (server hardening, 11 items — mostly clear), Phase 5 (P5-2..6).
  Nothing committed yet.

  DONE — build prunes .ruff_cache/.impeccable/__pycache__/etc from the staged package.
