Applies rule 32's migration exception: each header still says what the
schema was, what changes and what it prevents, but task, milestone,
decision and rule ids are replaced by the practice they stood for, the
operator quotes by the decision, single-install counts are dropped, and
pointers to a deleted package and an external design doc are gone.
golang-migrate keeps no checksum, so editing applied migrations'
comments is safe.

M489 step 1. The event bus is fire-and-forget, so a client that isn't
connected never hears that a request completed or that tracks went missing.
user_notifications is the durable record; the bus only nudges.
- Migration 0073: user_notifications (kind CHECK-gated, payload jsonb,
read_at, coalesce_key, emailed_at) and user_notification_prefs (per user,
per kind: inbox, phone, email). A missing pref row means the kind's
defaults, so nothing is seeded.
- internal/notifications.Notifier is the only writer. It resolves recipients
(admin kinds reach admins only, and never the excepted user), honours the
inbox pref (phone and email ride on it), writes, and publishes a
contentless notification.created nudge per recipient.
- Burst-prone admin kinds coalesce into one unread row: tracks_missing and
scan_failed add up their counts, duplicates_found and playback_errors take
the latest total. Once read, the next event is a new row.
- Retention: read rows go after 90 days, anything after a year, on the
library_changes compactor's daily shape.
Tests: unit (channel rules, kind table) and integration (recipients, nudge,
coalescing both ways, prefs, owner-scoped idempotent mark-read, every kind
against both schema CHECKs, retention cut-offs).
