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.
Two approved data-model changes.
P1-9 — ingest idempotency. A POST can succeed server-side but time out
client-side; the edge then re-queues and re-sends the same event, so the
cloud stored duplicate alerts. The edge Event now carries a stable
event_uuid (uuid4 hex) generated once at creation and preserved through
the offline queue and every retry. Cloud: 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 (catches the insert-race PDOException and returns the
winner).
P3-2b — site-scoped access control. site_scope was stored in the session
but never enforced, so any authenticated user could read every site's
worker snapshots (PIPA). Added devices.site; ingest denormalizes it onto
events.site (server-derived from the authenticated device_id, never
client-supplied). App\Security\SiteScope centralizes the rule (NULL scope
= global operator). The event list filters in SQL (page(...,$site)); event
detail + acknowledge and the snapshot proxy guard per-row and return 404
(not 403) cross-site so existence never leaks.
Schema migration ALTERs and per-device/user provisioning UPDATEs are
documented at the bottom of schema.sql.
Tests: edge queue round-trip keeps the uuid; repeat-uuid dedups to one
row; list scoped to caller site; detail cross-site 404; snapshot
cross-site 404 / same-site 200; event_uuid validation. phpunit 97 passing
(4 skipped: PDO), pytest 158 passing (2 skipped).

Implements Task 16 (final, P1-B): App\Db\Database::connect(Config): PDO
factory and the 9 App\Repository\Pdo\Pdo*Repository classes backing the
repository interfaces consumed by controllers since T1-T15, all-prepared
statements, plus cloud/schema.sql (MySQL 8 DDL) and cloud/docs/cloud-deploy.md.
Security hardening incorporated per accumulated task reviews:
- PdoNonceRepository: nonces.nonce is PK; duplicate remember() throws instead
of racing seen() (closes T7 TOCTOU).
- PdoRateLimiterRepository::hit(): atomic INSERT ... ON DUPLICATE KEY UPDATE
upsert on (rate_key, window_start), no read-modify-write race.
- PdoSnapshotRepository::pathByUuid(): validates 32-hex uuid before building
any filesystem path (closes T12 path-traversal risk).
- PdoZoneRepository::save(): update path is ownership-scoped by
(zone_id, device_id, camera_id); throws on mismatch instead of silently
overwriting an unrelated zone (closes T13 cross-tenant overwrite risk).
- Database::connect(): ERRMODE_EXCEPTION, EMULATE_PREPARES=false, FETCH_ASSOC.
cloud/tests/PdoIntegrationTest.php round-trips Nonce/Event/Zone against a
real sqlite :memory: DB, gated via markTestSkipped when pdo_sqlite is
unavailable (this host has pdo_mysql only, no pdo_sqlite) -- suite stays
green with 4 tests skipped.
Full suite: 59 tests, 114 assertions, 4 skipped, 0 failures, 0
warnings/deprecations. php -l passes on all new files and on
cloud/public/index.php (T15), which references all new FQCNs.
