Two independent adversarial reviews (codex CLI + a 6-dimension verification
workflow) of the delivery-hardening branch surfaced ~40 findings; this closes
the confirmed correctness/security/deploy blockers plus a codex re-review pass.
edge:
- geometry: track_displacement per-second threshold recalibrated (0.02->0.25,
env-tunable via MOTION_THR, validated finite/positive); confidence-filter
keypoints with a bbox-center fallback so hallucinated points don't fake motion
- fall: low-confidence frames no longer cancel an active FALLING/FALLEN incident
(freeze + reset recovery timer so recovery needs a fresh confident streak);
baseline height only seeded from trusted frames
- queue: PostClient.send() returns a tri-state SendResult; only definite 4xx
count toward the poison drop cap, so a network outage (incl. 408/425/429/5xx)
never deletes queued safety events; legacy rows persist their minted uuid
- config: reject placeholder / http / short DEVICE_SECRET at startup
- zones: warn+skip legacy pixel-space polygons that would silently match nothing
cloud:
- zone endpoints wired into P3-2b site-scope (cross-site read/write/delete
closed) + role gate on list; catch narrowed so DB faults surface as 500
- snapshot purge keeps the DB row when unlink() fails (no untrackable PIPA orphan)
- ingest dedup path re-stores missing snapshots (+ short-write guard); UNIQUE
(event_id, content_hash) makes recovery idempotent under retry/race
- event list cursor carries full-precision occurred_at (no float rounding at the
page boundary); string keyset end-to-end
- SiteScope '' fails closed (only NULL is global); dashboard fetches full page cap
- runnable migration (site/event_uuid + backfill ordering + indexes); rate-limit
reap fails open
deploy:
- offline bundle hashes EVERY file (fatal on missing/failed/injected; models in
SBOM; arch in tarball name; REQUIRE_SIGNATURE option)
- installer verifies before any mutation, Hailo arch preflight before install,
atomic src swap, backend reconcile preserves a working operator choice
- systemd DeviceAllow=char-dma_heap (the /dev/dma_heap/ dir form was inert)
Verified: edge pytest 165 passed / 2 skipped; cloud phpunit 109 passed / 4
skipped; deploy scripts bash -n clean. Reviewed by codex twice (findings +
fixes) with the second-pass findings folded in.
The offline bundle shipped unpinned pip deps with no digests, no SBOM,
and no signature — an air-gap target can't re-resolve from PyPI, so a
truncated or tampered wheel would install silently.
build_offline_bundle.sh now emits, from the resolved wheelhouse:
- SHA256SUMS — sha256 of every wheel + model
- requirements.lock — exact name==version pins for a reproducible rebuild
- sbom.json — CycloneDX 1.5 components (name, version, pypi purl, sha256)
- SHA256SUMS.asc — optional detached GPG signature when SIGN_KEY is set
MANIFEST advertises the integrity set and whether it is signed.
install_offline.sh verifies `sha256sum -c SHA256SUMS` (and the signature,
if present) BEFORE any pip install, hard-failing on mismatch; older
bundles without the file pass with a warning.
The generation logic was verified end-to-end on a synthetic stage:
requirements.lock/SHA256SUMS correct, `sha256sum -c` passes, sbom.json is
valid CycloneDX JSON. Both scripts pass `bash -n`.
Tests (test_deploy_artifacts.py): pinned integrity manifest is emitted
(+ optional SIGN_KEY), installer verifies integrity before install.

The air-gapped bundle never fetched the Hailo HEF, so an offline Hailo
install had no pose model. Two latent breaks also made the offline path
unusable regardless of P5-3:
- build [2/5] ran `fetch_movenet` unconditionally; with the MoveNet
source unreachable that aborted the whole build under `set -e`.
- install_offline copied only `*.onnx`, so even a HEF placed in the
bundle never reached $PREFIX/models for the backend gate to find.
Fixes:
- build_offline_bundle.sh fetches the $HAILO_ARCH (default hailo8) HEF
via edge.tools.fetch_hailo_hef (pinned sha256, aborts on mismatch) and
stages yolov8s_pose.hef. MoveNet ONNX is now optional (guarded fetch →
Hailo-only bundle if unavailable). onnxruntime moves to a best-effort
optional wheel. MANIFEST lists models + available pose_backends.
- install_offline.sh copies *.hef (and tolerates a missing *.onnx).
Tests (test_deploy_artifacts.py): bundle fetches+stages the HEF, MoveNet
is optional (guarded), installer copies the HEF. Both scripts pass
`bash -n`. Full python suite: 152 passed, 2 skipped.

- P5-2 [H] build_offline_bundle.sh native branch hard-fails when uname -m != TARGET_ARCH
(an x86 build was producing an aarch64-named tarball of x86_64 wheels).
- P5-5 [H] systemd unit adds DeviceAllow char-media + /dev/dma_heap for the CSI camera —
picamera2/libcamera on Pi 5 needs them or the unit denies its own camera. OFF-HW: verify on Pi.

Three intertwined bodies of work developed and tested together this session.
Full test suite green: python (edge) + phpunit (cloud).
## Edge/Pi install path
- setup_online.sh: apt-lock retry (apt-daily contention), Type=exec unit +
StartLimitIntervalSec in [Unit], journalctl-on-failure, crash-loop detection.
- onnxruntime is now best-effort (no sdist / no 32-bit-ARM wheel); [6/8] probes the
real backend and hard-fails if none works.
- Hailo HEF auto-fetch: edge/tools/fetch_hailo_hef.py (pinned sha256, refuses to guess
8 vs 8L, HAILO_ARCH override for serial-less boards); hailo_pose.py run() timeout fix.
- install_offline.sh: mirrors the backend gate; onnxruntime optional.
## Cafe24 cloud package (cloud/deploy/)
- build_cafe24_package.sh emits move_detect_app/ (private, one folder) + www/move_detect/
(docroot subdir); no-dev classmap autoloader; preflight.php; hardened .htaccess.
- Subdirectory mount support: Request::baseFrom/pathFor strip the mount prefix; index.php
walks up to find the app root; views/JS prefix every URL with APP_BASE; session cookie
scoped to the mount.
## Delivery audit — silent-failure & correctness (docs/delivery-audit.md)
All 4 blockers + all Phase-1 silent-failure + Phase-2 HIGH correctness:
- Edge cloud clients send a custom User-Agent (cafe24 WAF blocks python-requests) and
allow_redirects=False.
- Daemon fails loud on blank CAFE24_URL/DEVICE_SECRET; run_loop logs swallowed exceptions;
heartbeat carries real fps + per-camera health; UvcSource reopens a dead camera;
offline queue is size-capped and drops poison rows; TARGET_FPS/QUEUE_DB validated.
- Zone coordinates normalized 0..1 on both sides (were canvas-px vs camera-px — every zone
misplaced); pinch zones emit PINCH/HIGH (were downgraded to WARNING).
- Fall detection uses bbox cues when keypoints are low-confidence (occluded fallen person);
ghost incident not cancelled by a bystander; displacement normalized per-second (FPS-invariant).

Create the venv with --system-site-packages so it can import the Pi system packages
that are not pip wheels (hailo_platform via hailo-all, picamera2 via python3-picamera2).
Add CAMERA_BACKEND/CSI_DEVICE to the env template and document the Hailo-8 + CSI
prerequisites and air-gap handling in deploy/README.
Offline-installable bundle (wheelhouse + model + source) built on a machine with
internet and installed on the air-gapped Pi with --no-index (zero fetches), plus a
systemd unit (auto-restart, device access, hardening) and env template. Runs the
package from source via python -m edge (no offline build backend). Drift-guard test
keeps the env template in sync with what the daemon reads and rejects inline comments
that systemd EnvironmentFile= would fold into values.
