The quiet-hours CHECK accepted a row with only one bound set, because a NULL comparison made
the whole condition NULL; it now requires both bounds explicitly. The migration has not shipped
yet, so it is corrected in place.
- Unit: quiet-hours math across midnight, time zones and daylight saving; VAPID key handling
(configured, generated once and shared, invalid); the web push sender (encrypted VAPID-signed
request, gone on 404/410, no private or non-https endpoints); the fan-out with fake senders.
- PostgreSQL: settings and subscription repositories (constraints, per-user removal, endpoint
hand-over, device cap, concurrent nudge cap, cascade on account deletion), delivery and
notify_user against a real main conversation, and every notification RPC through the API
including cross-user isolation and endpoint validation.
- .env.example documents the optional VAPID keys and VAPID_SUBJECT.
