Additive, v1-only backend contract for the Android app's opt-in push (Part 1 of
M7; docs/android/PLAN.md §11). The app is a pure consumer — this lands the
endpoints, fan-out, and relay it needs.
- Schema: push_devices (per-device endpoint) + notification_subscriptions
(per-user opted-in streams), FK→users ON DELETE CASCADE.
- Stream catalog + event→stream mapping (config/notificationStreams.js): public
streams (news.post, server.status, idoc.warning, champ.start, governor.election)
drawn ONLY from the SSE PUBLIC_KINDS allowlist; personal owner-keyed streams
(vendor.sale, house.idoc, account.login). Full-state upserts (champ/city) fire
only on a real transition via an injectable tracker.
- Fan-out (utils/pushDispatch.js): content-free tickles ({ stream, ref }) POSTed
to each subscribed device; never throws. Two producers — shardIngest.ingest
(beside the SSE broadcast) and the create/publish-post path (news.post).
Personal events resolve to the owner via shardLinks. SSRF guard: endpoints must
be HTTPS, non-private, and on the NTFY_BASE_URL/NTFY_ALLOWED_ORIGINS allow-set —
enforced at registration and every publish.
- Routes under the role-agnostic self surface (never /admin): POST|GET
/auth/me/devices, DELETE /auth/me/devices/:id, GET
/auth/me/notifications/streams, GET|PUT /auth/me/notifications/subscriptions.
Swagger regenerated (4 paths, PushDevice/NotificationStreams/etc. schemas).
- ntfy service in docker-compose.yml: pinned image, declarative ./ntfy/server.yml,
no published host port, anonymous unguessable topics (no accounts) — zero
interactive setup. No publish token required (content-free design); optional
NTFY_PUBLISH_TOKEN honored.
- Tests: pushDispatch (mapping, PUBLIC_KINDS gate, owner-keying, SSRF guard,
content-free payload) + notifications route auth gate. Full suite green (247).
