The offsite restore list rendered up to five inline forms per app row. Two of them —
„Helyreállítás az élő adatok közé (csak a hiányzó fájlok)" and „Teljes visszaállítás
(fájlok + adatbázis)" — were sibling buttons whose difference is whether the customer's
data comes back at all. That mis-selection CAUSED the round-2 incident: an operator who
had read the source pressed the missing-only button and /backup/offbox/reconstitute was
never hit (DIAG-immich-restore-round2-2026-07-19, finding 1).
The rule this establishes: two adjacent controls whose difference is "your data comes
back" vs "your data cannot come back" must never be distinguishable only by layout.
Each row now carries ONE „Visszaállítás…" entry linking to a per-app wizard at
GET /backups/restore/app?name=<app>: three intent CARDS with consequence sentences, a
visible phase strip, danger styling plus the R-43 double-confirm carried over verbatim on
the destructive one, and the pair-honesty panel bound to real OffsiteScratchPair facts.
deriveWizardStep is pure over (op running, size-gate flash, scratch ready); the step is
never accepted from the request, and a running op outranks a stale ?full_prep= so no
commit button survives into a restore. While ANY op runs every mutation form is suppressed
server-side instead of being offered and refused.
No new mutation endpoint: every card posts to the pre-existing /backup/offbox/* handler
with the same field names and gates, and the page works with JavaScript disabled.
internal/{backup,appbackup,selfupdate} untouched. R-45's job registry stays its own item.
Fixes a latent bug found on the way: offboxRedirectTo hardcoded "?" when appending its
flash, which against the wizard's ?name=<app> target would have buried the flash inside
the name value.
No new agent coupling — MinAgent stays 0.90.0.
Closes the two findings from DIAG-immich-restore-2026-07-19. Viktor deleted 11
immich photos to test offsite restore; both runs flashed success and the photos
stayed gone. Two independent defects.
R-43 — no offsite path could restore a database. All three buttons were
file-only: the two "visszaállítás" actions staged to a scratch folder and never
touched postgres, and place-to-live merged only MISSING files. For a DB-indexed
app the bytes returned and the app still could not see them. The dump was
carried INTO every snapshot and could never be replayed OUT of one.
New ReconstituteFromOffsite (/backup/offbox/reconstitute): safety dump → stop →
files overwritten to the snapshot version → start → the snapshot's own dump
replayed → health wait. Two invariants:
- nothing is ever deleted (-a, no --ignore-existing, no --delete): a file
created after the snapshot survives as an extra;
- the undo exists before the act — the pre-restore- dump is verified ON DISK
before anything is stopped, overwritten or replayed; if it cannot be taken
the operation refuses with zero changes.
The replay reads the SCRATCH unit: the live unit is never overwritten, so
replaying from it would replay the current DB over itself and restore nothing.
R-44 — a manual push shipped an unrefreshed dump (up to ~24h old). That day's
predated the customer's account by four hours and probed to asset:0/user:0/
album:0 inside 52MB whose bulk was immich's shipped geodata. Every run, manual
AND nightly, now refreshes dumps + units BEFORE capturing. Order is the
mechanism: the gap can only ADD files the DB does not reference yet, never
remove one it does. Manifests carry offsite_run_id + dumps_at, so coherence is
verifiable at restore time rather than assumed; the periodic refresh carries a
prior stamp forward and never invents one.
Honesty surfaces, all warn-level and none a gate: unstamped (pre-v0.148) pairs
report their skew, ValidateDump gained an EXACT-match accounts-table sniff for
customer-empty dumps, the completion flash states an outcome instead of a
mechanism, and the missing-only button now says what it does NOT do.
11 tests; 5 red-proofs run and reverted. Two of those found real test weaknesses
rather than confirming strength — the first undo mutation was caught by a second
guard, and the first table-matching test did not discriminate between the two
matchers at all. Both tests were rewritten to the cases that separate them.
NOT in scope: R-41's catalog invariant check, nightly cadence, retention, quota
math, tier-2, and v0.147.x progress semantics beyond one added phase line.
Live acceptance (§9) has NOT run: no capability-map flip, customer-restore row
stays MISSING, R-3 stays DRAFT.

The systemic complaint, twice in one evening: you press a button and nothing
happens. No progress, no ETA, no named result. Three worst offenders, fixed on
the two patterns already here (deploy 3-step panel, storage-init status poll).
No new framework — that is a ROADMAP item; three targeted cards ship tonight.
4a — a verification restore names its result. The flash said the app had been
restored "to a verification folder on the drive"; which folder, on which drive,
was invisible, so the customer could not go and look at what they had just asked
for. Full path now. The restore page gained a listing of existing verification
copies (app, size, date, path) — nothing anywhere showed these, so they piled up
and the only way to find them was SSH — each with a double-confirmed delete.
That delete is the only one this release adds, so it names a STACK, never a
path: the Manager resolves the name inside a backups/offsite-restore root it
computed itself and refuses anything landing outside. Red-proofed — neutralise
the name guard and stack:"" resolves to the offsite-restore ROOT and takes every
copy with it. Refusals are asserted as non-effects.
4b — Megosztás enable shows what it is waiting for. Enabling ran ReconcileSamba
synchronously inside the POST handler; on a golden without felhom-samba baked
that is compose pulling ~100MB, i.e. minutes of an apparently-hung form post
followed by "Beállítás mentve." whether or not anything came up. Detached +
polled now, distinguishing "képfájl letöltése" from "indítás" — decided BEFORE
the work starts, since afterwards the image is always present. Success is
probed, not inferred (compose up -d exits 0 on a crash-loop). The password form
starts the same job: with UserSet false reconcile deploys nothing, so on a fresh
box that is where the pull actually happens.
4c — "Távoli mentés most" streams real progress. restic was already reporting
bytes and percent; the runner seam used CombinedOutput() and discarded them. The
manual run now passes --json and scans stdout line-by-line: total bytes, percent,
current app. Manual only — the nightly stays silent, pinned by a test that fails
if it ever passes --json. The poll now arms unconditionally, closing a race the
manual trigger always ran: the redirect rendered before the goroutine wrote
LastStatus=running, so the poll never armed and the page sat static during the
very run just started. Red-proofed twice.
Also closes the golden/controller infra-image drift at the source: infra.Images()
derives from the existing pins and --print-infra-images exposes it, so the golden
bake can stop carrying its own copy. That copy had already drifted — felhom-samba
was never added, so the golden baked 3 of 4, which is why enabling Megosztás
pulled at runtime in the first place.

Part 4 — restore: RestoreSharesScratch + PlaceSharesRestore as SIBLINGS of the
per-app scratch/place pair. Files merged missing-only (never overwriting), each
destination PREFIX-ASSERTED against registered LIVE storage roots; definitions
merged with existing-wins; ReconcileSamba via a seam (backup must not import
stacks); credential restored best-effort into the samba named volume.
New routes POST /backup/shares/{restore,place} + a restore-page entry that renders
'Megosztasok', never the raw reserved key.
Also adds scratchJoin: reconstructing an absolute captured path under a scratch
must strip the volume name rather than rely on filepath.Join.
Part 5 — liveness: EffectiveProtected gains a settings-backed dynamic extra so the
samba CONTAINER (not the stack name — they differ) is watched exactly while sharing
is on. FINDING: the issue -> health 'fail' -> existing health_critical event ->
alert -> Hungarian degradation e-mail path needs NO further change, and introduces
no new event type, so the allowlist gotcha does not apply.
Part 6 — UI: per-tier backup status lines on the Megosztas page (amber only on
deviation). Verified the two warning-prose sites (offbox_capture/tier2_capture)
only ever receive per-app stack names, so no mapping is needed there.
RED-PROOFS RUN AND REVERTED (both fired):
4. prefix-assert removed -> place-guard traversal test FAILS
5. dynamic samba extra removed -> Scenario E enabled-case FAILS
- backups_restore: placeholder 'Opcionális jelszó' + helper under the field
('Üresen hagyva a csomag titkosítás nélkül készül.') — the long clipped placeholder is gone
- app_import: the bundle-password input picks up the standard .form-input class
(was a bare browser-default input)
