ONE additional restic call tagged [felhom-offbox, _shares] carrying the payload
staging dir + every mandatory share folder. Hooked into runOffboxInternal AFTER the
per-app loop and BEFORE retention, so forget --group-by host,tags covers the _shares
group with no flag change. Reuses resticStep, the caller's repo-ensure and
single-flight, and the SAME enlargement-gate arithmetic.
- quota gate degrades the push to MANIFEST-ONLY, never to nothing
- EnlargedBlocked keeps the RAW _shares key (templates index by it); the display
mapping applies only at the notification + Hungarian-prose boundaries
- OffboxTarget gains SharesLastRun/Status/Count for per-tier page truth
- zero-toggle notice suppressed when the shares leg provided coverage
- reserved-name defense: an app keyed _shares is excluded from the run loudly
RED-PROOFS RUN AND REVERTED (all fired):
1. shares leg appends into the app's argv -> isolation test FAILS
2. mandatory->offsite mapping inverted -> Scenario A + B FAIL
3. manifest-only degradation dropped -> Scenario C FAILS
Sibling shares source for the local cross-drive tier. Reuses the tier2Mirror seam,
selectTier2TargetFrom (narrow source-drive seam extracted from selectTier2Target),
tier2ReconcileRoots (pure extraction), tier2SafeRemove, the marker-LAST discipline
and the recordTier2* helpers. Per-app paths are untouched.
- shares_payload.go: deterministic _shares-manifest.json + best-effort passdb capture
- tier2_shares.go: per-source-drive legs -> cross-drive target, payload, marker LAST
- infra.SambaContainerName/SambaPassdbVolume/Mount: single source of truth for the
container identity (renderer, stacks execs, backup execs, monitor all read it)
- RESERVED-NAME finding: ValidateSMBShareName did NOT exclude a leading underscore,
so "_shares" was an accepted share name. Now refused; RunAllTier2 additionally
skips a "_shares" stack loudly as defense in depth.
- fix: shareSourceDrive returned a slash-normalised path, which made the target
selector's source-drive equality check miss (a group could target its own drive)
