- /api/v1/devices (register) + /api/v1/devices/remove — auth-required, validates
platform (ios|android), upserts by token; e2e covers register/validation/auth/remove.
- db device_tokens table + deviceTokens repo.
- push.js: FCM HTTP v1 (Android) and APNs token-based over HTTP/2 (iOS) folded into
the single push.sendToUser path alongside Web Push; each transport independently
config-gated and a silent no-op without creds. Dead tokens pruned on 404/410.
- docs: CLIENTS.md Phase B updated; DEPLOY.md env table adds FCM/APNs vars.
e2e 117/117.
