The recovery unit on the customer's drive now carries the PORTABLE secret
class, so Tier-1/Tier-2 restore no longer depends on the whole-guest tier.
A customer needs the drive and nothing else.
Part 0's rulings overturned the brief's recommendation, on evidence:
- the data_key flag is untrustworthy (4+ encryption keys the catalog itself
labels as such are unflagged) -> R-127
- a DB password is not resettable in practice: POSTGRES_PASSWORD is ignored
once PGDATA is non-empty, so a regenerated value leaves the app unable to
authenticate against its own restored rows while the dump replay still
reports success (proven on a throwaway postgres:16-alpine)
Ruling (operator): type:secret travels, type:password never does, minus the
nonPortableSecrets code register. Plaintext -- withholding the internet-
reachable class is what licenses that, and the two are coupled.
Precedence: the UNIT WINS over the guest -- the unit's secrets were captured
in the same run as the dumps beside them, so they match the data being
restored. The fail-closed data-key gate is unchanged.
Secret values are never logged; the manifest records NAMES only.
${IMPORT_PATH} = <system namespace root>/userdata/import — ONE drop-zone per box,
on the system drive, injected at BOTH compose-env builders with NO per-drive
fallback (unresolvable leaves it unset so compose fails loudly rather than
quietly building a second, dead drop-zone).
Third BindRoot (RootImport) + Import list in BackupSpec, extended through
ValidateBackupSpec/ClassifyBinds. Load-bearing: a stale `userdata: import/<app>`
entry against the moved bind would be a WHOLE-BLOCK reject, taking the app's
mandatory hdd classification with it.
Exhaustive-root audit: resolveAbs/structuralGuard/ComputeCaptureSet/
ComputeFabBuckets now take importRoot explicitly (an import bind resolved
against hddPath would name a directory on the wrong drive); unresolvable is
refused loudly into Skipped. GetImportRoot added to both provider interfaces.
Catalog-derived skeleton: UserdataSkeleton() -> UserdataSkeletonCarry() +
BuildUserdataSkeleton(), SORTED. The carry-list makes zero-removals true by
construction (`documents` is in no catalog app but on both boxes) and is the
fresh-box floor. The sort is not tidiness: the naive map-order derivation
measured 20 distinct outputs from 20 identical runs, which with fbNeedsRecreate
is a fleet-wide FileBrowser restart loop.
One authoritative compose parser: ParseComposeUserdataMounts now delegates to
ParseComposeClassifiableBinds. Import root excluded from per-app migration.
Surfaces: FileBrowser /srv/beolvasas source; app-page "Hova tegyem a fajlokat?"
with PathEscape deep links (never QueryEscape) and class-driven copy;
data_paths: annotation with the Fork-3 asymmetry; system-owned beolvasas SMB
share refused server-side at handler AND store, button omitted in template.
Caught on the way: the sharing template's row struct was function-local, so
adding {{if .System}} would have 500'd every share row. ShareRow is now
package-level and the render test uses the handler's own type.
Tests 915 -> 949, all green. MinAgent unchanged.
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.
Task 2 of the backup-classification-redesign arc. Ships the referential-
coupling classification as DATA + PARSER + PURE CLASSIFIER, deliberately
inert — no backup tier changes behavior. Task 3 (tier policy engine) and
Task 4 (manual .fab UI) consume it.
- appbackup/classify.go: BackupSpec/BindSpec/ComposeBind/ClassifiedBind;
ClassifyBinds (SQ5 two-level default — explicit beats :ro; unlisted
writable→mandatory, unlisted :ro→excluded; nil spec→legacy/false);
ValidateBackupSpec (whole-block-reject on any defect, first defect named).
- stacks/classify_binds.go: ParseComposeClassifiableBinds — ${VAR}-relative
binds + :ro flag (NOT ParseComposeHDDMounts/ExportDataMounts, the traps).
- Metadata.Backup + LoadMetadata as the single validation choke point (bad
catalog block → nil + one ERROR → legacy, within one sync cycle).
- Manager.ClassifiedBinds + StackDataProvider.GetStackClassifiedBinds seam
(delegated by stackAdapter, nil-stubbed in every fake) — wired + tested
now so Task 3 consumes a tested seam.
INERT: full pre-existing suite green with zero test-logic edits. +14 tests;
red-proofs RP-1..RP-4 confirmed. The 13 catalog backup: blocks ship in the
same app-catalog change (this controller deploys first).

Adds an in-process orchestration test for RestoreFromRecoveryUnit: success path
calls recreate with non-secret env + recovered secrets merged; data-key-missing
path is REFUSED and recreate is never called. Makes Manager.isDebug nil-safe
(behavior-neutral in prod; cfg is always set) so the gate/orchestration are testable.

Restore recreates an app from its on-drive unit + the guest's own secrets,
regenerating nothing. reconcileRestoreSecrets (pure, unit-tested) merges the unit's
non-secret env with secrets recovered from the live app.yaml and FAILS CLOSED if a
data-encrypting key is unrecoverable (refuse — a PBS whole-guest restore is needed —
rather than regenerate and corrupt). Resettable secrets missing → warn + proceed.
- backup: RestoreFromRecoveryUnit (manifest -> recover secrets -> gate -> restore
volumes -> recreate definition + redeploy w/ re-pull); falls back to volume-only.
- seams: RecoverStackSecrets/RecreateStackFromUnit (adapter +encKey),
stacks.RedeployFromEnv. Wired into /backup/restore.
- tests: gate (refuse/proceed/verbatim) + data_key parsing.
Gate + reconcile + data_key parsing unit-tested; capture live-validated (v0.53.1).
Full readable-data e2e vs AdventureLog needs the auth-gated dashboard restore — pending.

CaptureRecoveryUnit now builds content in memory and skips writes when the unit
is already current (checksum + dump-set + version), so it can run from RefreshCache
(startup + every 5m) without thrashing the USB drive. Units now exist shortly after
startup and track config changes without waiting for the daily DB dump. +idempotency test.
