The internal/vaultik tests took 36 to 56 seconds under go test -race and ran past the 90-second timeout when the host was busy. Tests that built the same backup now copy one shared backup, and the interruption tests use smaller sources. No assertion is weakened and no test is removed. Measured back to back on next under the same load, the package takes 55% of its former time.

`remote nuke` took a destination store it could not list, or one
without `vaultik-destination.txt` while the local index held
snapshots, as a warning: it then cleared the local snapshot records,
and for an unplugged volume's empty mount point reported the store
empty and exited zero. Nuke now fails on either before it removes
anything, without its advice to run it again, which would fail the
same way. The bulk remove it runs fails on either too; only a
local-only remove still goes on with a warning. Nuke also deletes each
snapshot's remote metadata before its local record, so a failed delete
keeps the snapshot in the local index rather than leaving it on the
store as a remote-only snapshot.

Every backup writes vaultik-destination.txt at the destination root.
While the local index holds snapshots stored there, a destination
without it is not present: snapshot create refuses before writing,
prune and snapshot purge fail, and snapshot list and snapshot remove
act as for a destination that cannot be listed. snapshot create and
snapshot remove check it first. remote nuke deletes the marker last.
The file:// backend never creates its destination directory, which
protects a directory on a removable volume, not a mount point.
Tests back up into directories that exist; fixtures for a written
destination carry the marker.
Judgement call: the marker is rewritten on every backup.
Deviation: for the complexity limit, two blocks moved, unchanged, into
snapshotNamesToCreate and confirmRemoveSnapshot.

In the Dockerfile test phase, internal/vaultik spent 23.6s of 31.9s in
36 tests run one at a time. 24 of them were serial only because they
call log.Initialize; they now call it before t.Parallel(), so the
logger is replaced before any parallel test runs. The 12 still serial
change the umask, TMPDIR, os.Stderr or time.Local.
TestLargeDatasets took 8.4s of the 9.8s internal/database run by
committing each of its 1,500 inserts on its own; it now makes them in
one transaction. TestDedupOnlySnapshotRestores gives its second backup
its own snapshot name instead of sleeping 1.1s for a new snapshot ID.
Model: opus-5-5
The warning for a config file that others can read always said the
file contained S3 credentials, so a file:// config with none got a
false claim. When s3.access_key_id or s3.secret_access_key is set it
now says the file may contain them, because Load sees the values only
after smartconfig has replaced any ${...} reference, so a set
credential need not be in the file. Otherwise it says the file is
readable by others.
snapshot purge wrapped the listing error, which already starts with
"listing remote snapshots:", in that prefix a second time.
syncWithRemote now returns it unwrapped, as CleanupLocalSnapshots
does.
Model: opus-5-5
The file backend listed a destination directory that does not exist as
an empty store. With the volume unplugged, snapshot list reported every
local snapshot as missing from the store, snapshot remove said it had
removed metadata it never reached, and prune dropped every local
snapshot record. List and ListStream now fail when the destination
directory is missing, so those commands take their existing path for a
store that cannot be listed. A missing prefix under an existing
directory is still an empty listing, and a first backup still creates
the directory.
Three tests listed a file:// destination nothing had created; they now
create it.
