R-486 (P1): removing an app with its backups KEPT keeps its Tier-2 record,
so the second-drive restore is no longer refused over an intact mirror.
R-484: postgis/pgvector/timescaledb images are Postgres (logical dumps).
R-485: the backup card sizes the recovery unit and the mirror(s).
R-480: a held update's sentence leaves the card once the hold is lifted.
R-477: the update's off-site lookup is one snapshots call, no stats.
R-478: a copy older than this install's deploy does not count.
R-474: "delete backups" deletes the unit, the mirror(s) and the prefs.

Closes R-47. No new agent coupling — MinAgent stays 0.90.0.
The replay needs a running DB container, so both restore paths started the
WHOLE stack first, giving the application a window to rebuild the very schema
objects the dump was about to create. Measured live on 2026-07-19 (H4,
DIAG-immich-restore-round2): immich-server rebuilt clip_index two seconds
before the dump's CREATE INDEX, the replay aborted "already exists" under
ON_ERROR_STOP=1, and immich reported schema drift. The data survived only
because pg_dump emits COPY before CREATE INDEX.
Both paths now open a DB-ONLY window: only the stack's database service(s)
come up, the dump is replayed with the app still down, and the full start
runs only after the replay exits 0. Fail-closed: a dump with no identifiable
DB service refuses BEFORE the first mutation. Every exit from the window
still does a best-effort full start, so a failed restore never leaves a box
with a database and no application.
New: appbackup.DBServiceNames (yaml.v3 services-map parse — never a line
scan; immich's top-level volume keys are the decoy) sharing dbTypeForImage
with DiscoverDatabases; stacks.Manager.StartStackServices (refuses an empty
list — argument-less `up -d` is a full start); RedeployFromEnv split into
PersistUnitRedeployConfig + its unchanged tail. StackDataProvider's
RecreateStackFromUnit becomes RecreateStackDefinitionFromUnit — the hidden
`up -d` inside the old name is what carried the defect on the local path.
19 new tests (ordering plus state-at-replay-time, zero-mutation fail-closed
effects, replay-failure bring-up, parser decoys, empty-list refusal); three
companion red-proofs run and reverted. 23/23 packages green.
Not yet live-validated: STOP-1 supervised reconstitute, golden 0.153.0.
