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).

- P4-9 [L] logout() rotates the session id before wiping (was regenerate-after-destroy → warning).
- P4-10 [L] EventValidator caps device_id/camera_id (64) + zone_id (32) → 400 not a MySQL
'Data too long' 500 the edge retries forever.
- P4-11 [L] Request::pathFor collapses leading slashes so '//api/events' isn't misrouted to '/events'.
- P5-6 [L] cafe24 build prunes dev caches (.ruff_cache/.impeccable/__pycache__/…) from the package.
python + phpunit (86) green.
