sneak ac489af3d7 Make remote nuke delete leftover .partial uploads (closes #281)
check / check (push) Canceled after 0s
The file and rclone listings skip an object whose name ends in
`.partial`, the temporary name a `file://` or rclone upload writes
before moving the object into place. `remote nuke` deletes only what
the listings return, so it left the `.partial` objects killed uploads
leave behind and still reported the destination store empty.

Storer gains DeletePartialUploads. The file and rclone backends remove
every `.partial` object under the prefix; S3 has none to remove, since
it shows an object only once its upload completes. `remote nuke` calls
it for `metadata/` and `blobs/` as its last step.

Empty directories under a `file://` destination are still left behind.

Model: opus-5-5

# Completed Steps # Completed Steps
- 2026-10-13: Stopped `remote info` counting a file under `blobs/` that
is not a blob as an orphaned blob
([issue #295](https://git.eeqj.de/sneak/vaultik/issues/295)). A stray
file such as `.DS_Store` was reported as an orphaned blob and the
report advised running `prune`, which skips such a file and deleted
nothing. `remote info` now takes its blob list from the same listing
`prune` uses, in the table and in `--json`.
- 2026-10-13: Made `snapshot remove` fail for a snapshot that does not
exist ([issue #293](https://git.eeqj.de/sneak/vaultik/issues/293)).
The command never checked the ID: it reported the snapshot removed
from the local database and from the destination store and exited 0,
under `--json`, `--dry-run` and `--local-only` too. An ID that names
no snapshot in the local index or on the destination store is now an
error; with `--local-only`, the snapshot must be in the local index.
The command now reports a removal from either side only when one
happened, and `remote_removed` is true only when metadata was deleted.
- 2026-10-12: Bound the local index to the destination an `s3.*` config
names ([issue #298](https://git.eeqj.de/sneak/vaultik/issues/298)).
Only `storage_url` was checked, so after `s3.bucket` or `s3.prefix`
changed, the next backup treated every chunk as already stored,
uploaded nothing, and completed a snapshot that could not be restored.
Without `storage_url`, the local index is now bound to `s3.endpoint`,
`s3.bucket` and `s3.prefix`, and a change is refused as a changed
`storage_url` is.
- 2026-10-12: Rejected a retention duration longer than about 292 years
([issue #289](https://git.eeqj.de/sneak/vaultik/issues/289)). The
number given to `--older-than` or `--keep-newer-than` was multiplied
by the length of its unit with no limit, so from `293y`, `15251w`,
`3559mo` or `106752d`, or a sum of parts such as `200y200y`, the
result wrapped to a negative duration. The cutoff then lay in the
future, every snapshot of the name was deleted, the one just made
included, and the command exited 0. Such a duration is now rejected
as invalid and nothing is deleted.
- 2026-10-08: Made a backup cancelled under `--skip-errors` stop at once
([issue #286](https://git.eeqj.de/sneak/vaultik/issues/286)). After
Ctrl-C or SIGTERM, phase 2 treated the cancellation error from each
remaining file like an unreadable file: it opened the file, printed an
error line for it, counted it as failed and went on to the next one.
The run now stops at the first file after the cancellation, and no
file is counted as failed because of it.

only records such an entry in the local index, since it has no data
