Codex + CodeRabbit review fixes, all verified against current behavior:
- Web Push: single-writer VAPID provisioning via a new conditional
SetIfAbsent settings write (no split-brain identity across nodes), and
read/decode failures now surface instead of silently rotating the
keypair; the eager-provisioning goroutine joins the shutdown WaitGroup
- Web Push: endpoint reassignment purges the previous owner's pending
attempts inside the upsert transaction, with an ownership re-check at
send time
- Webhooks: per-profile cap enforced atomically (advisory-locked
count+insert), typed pgconn unique-violation mapping, create-time
type/URL mismatch rejection, send-time HTTPS re-check, and Retry-After
HTTP-date support (shared, clamped parser also used by web push)
- Delivery workers: transient delivery-row lookup errors leave the claim
to lease expiry instead of permanently failing the attempt
- Interest: history-only imports now feed the index (userstore history
hooks + completed-history folding in recompute/rebuild), rebuild also
recomputes existing interest rows so removed sources get cleaned up,
and failed flush mutations requeue (bounded) instead of dropping
- Retention: read notifications age from read_at, not created_at
- Startup: scan queue workers start only after the availability detector
is wired, so resumed scans cannot skip availability recording
- mail: settings-store read failures propagate instead of reading as
"not configured"
- DB: new migration adds episode ordinal/key CHECK constraints
- Web: service worker restricts notification clicks to same-origin URLs,
preferences popover gets an error+retry state, and the realtime
profile-rebind backoff grows to 5 minutes to keep shared channels
stable through notifications-only outages

Implements the notification system foundation and all v1 delivery channels
that need no external infrastructure (specs 00/01/04/05 in
docs/superpowers/plans/notifications/):
Foundation (spec 01):
- episode_availability seeding + per-library seed markers: "newly available"
means newly released to this server, so back-catalog imports and first
scans never flood (verified on dev: 1.13M episodes seeded silently)
- release_events -> profile_series_interest fanout worker with settling
delay, per-series burst caps, FOR UPDATE SKIP LOCKED multi-node claims,
and a guarded last-notified cursor
- interest index maintained via a userstore provider decorator so every
favorites/watchlist/progress mutation path (REST, jellycompat, imports,
playback) feeds it; progress writes only recompute on state transitions
- durable per-profile inbox + read state, forward-sync cursor API,
websocket channel with short-lived single-use handshake tickets
- web UI: sidebar badge, inbox page, toasts, per-profile preferences
- startup/daily tasks: availability seeding, interest rebuild, retention
Outbound webhooks (spec 04):
- Discord embeds (text-only per the v1 privacy contract) and generic
JSON signed Stripe-style with per-webhook secrets
- HTTPS-only + private-destination guard enforced at registration and at
connect time (DNS-rebinding mitigation); URLs/secrets encrypted at rest
- durable per-target outbox enqueued in the fanout transaction, lease-based
claims, 24h exponential retry, 3x-consecutive-4xx auto-disable with an
in-app notice (loop-guarded)
Web push (spec 05):
- VAPID keypair self-provisioned at startup (single atomic JSON setting,
private half encrypted at rest) — no third-party accounts needed
- payloads E2E-encrypted (RFC 8291); 404/410 treated as unsubscribe
- service worker + subscribe flow in Settings -> Notifications
Shared SMTP core (internal/mail):
- feature-agnostic mail.Sender over live email.* settings, STARTTLS or
implicit TLS, encrypted password, admin Email settings page with
synchronous test send; no consumer yet by design (digest is v1.5)
APNs/FCM (specs 02/03) are deferred to v2; the capability endpoint reports
them unavailable so clients render truthfully.
