R-650: internal/dockerexec — every docker exec routed through it; under
go test a real docker is refused (opt-in FELHOM_TEST_REAL_DOCKER=1; a stub
under the temp dir is allowed). api/stacks/web tests run under a silent
stub (TestMain). TestR650_NoBareDockerExec pins it repo-wide.
R-640: a dump without its engine's completion marker is refused before
the first mutation (unit + off-site restore) and again before any load.
R-499: the Tier-2 page's system-disk sentence has four true branches.
R-518: the backup button states the measured ~8 min stop.
R-626: measured on 9202, not reproduced.

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)
