- Review draft sync is a pure helper (format.ts): incoming values are
ignored while a save is in flight, and a failed save restores the
previous synced value, so the typed text is kept whichever of the
rollback and the error callback lands first. Tests cover both orders.
- A failed background refetch keeps showing the cached entry instead of
the error screen (it unmounted the review box mid-outage).
- History restore joins the entry-patch mutation scope.
- updatePreferences: read-modify-write in a transaction, row locked on
Postgres.
- Invalidate auth-status after register; out-of-range rating errors speak
in the user's scale.
