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.

THE WALK FOUND THREE MORE ENTRY POINTS THAN THE REPORT DID. R-411 named one missing
acquireRunning. Fixing it and then pinning the invariant with an AST walk surfaced FOUR in
total, all of which issued restic commands with no flag:
RestoreOffboxScratch - the reported one
OffboxRestorePrepareFull - the SECOND request in the customer's own two-step full-restore
flow, and the one that actually shells `restic stats`. The UI
reaches it FIRST, so flagging only the restore would have left
the collision reachable by the ordinary path.
RestoreSharesScratch - R-411's exact shape on the shares tier: unlockStale + resticStep,
a live web caller, and its sibling PlaceSharesRestore has always
taken the flag.
RestoreOffbox - no production caller today, but the same dangerous pattern.
Flagged rather than left for a future caller to inherit.
OffsiteInventoryList is REGISTERED EXEMPT with its reason: it issues only `restic snapshots
--json`, measured on demo-hp 2026-08-31 not to take a lock, and flagging it would make
browsing a page refuse during a backup for no safety gain.
THE REAL DELIVERABLE IS THE WALK, not the acquire. offbox_integrity.go:28 asserted "Every
off-site operation takes acquireRunning" since v0.227.0, nothing checked it, and it was false
for months - the ninth instance of this project's most-repeated class. The walk is an AST
pass, not strings.Contains, because a commented-out call still contains the string.
Red-proofed twice: removing the acquire fails it naming RestoreOffboxScratch; an
unregistered fake entry point fails it naming the fake.
R-407: "It NEVER writes to the repository" corrected in place, not deleted (R-360's rule).
`check` takes a lock - and so does `restic stats`, which is the fact nobody had and the one
that made R-411 possible. Both recorded where the next reader will meet them.
R-414: the proof could not run at all on a box with no registered drive. Part 2.1's
determination came out as neither "missed" nor "deliberate": R-356's own test comments say
the scratch resolver "still resolves ... only the DESTINATION moves", so it was OUT OF SCOPE,
and it was never ruled out on state-only grounds - the one comment about a systemDataPath
fallback belonged to PlaceOffsiteRestore, concerned bulk USERDATA, and R-356 overruled even
that. So 07 section 6.3's rule applies and now has a fourth consumer.
The fallback is SCOPED, because the two callers ask different questions and one predicate
answering both is the R-356 defect itself: a UNIT-ONLY restore may fall back to the system
data path (07 section 7 records as FACT that a driveless app's unit already lives there
indefinitely, and that the same-device placement is intended); a FULL restore keeps today's
refusal, because it pulls bulk userdata onto a state-only tier.
And the silence ends either way: a proof that cannot start now records ProofResultCannotRun
rather than an Err, so last_proof_result is never ABSENT - absent already means "controller
too old", and a second meaning on the same field is the StatsKnown trap one level up. It is
recorded WITHOUT advancing per-snapshot due-ness, so the app stays retryable once a drive is
registered.
R-412 leg 1: a per-app push whose unit carried no dump and no tar now says so, at WARN.
Wording only - no guard, and the capture is untouched (08 section 8.2). Leg 2 stays OPEN.
16 new tests, 1689 -> 1705. Full suite 28 packages rc=0, all 13 controller gates OK.
Red-proofs run and reverted byte-identical for A3/B1 (twice), C1 and D1.
