bug
forget()` always deletes index entries, including when `dry_run` is true, so `POST /v1/admin/cache/sweep?dry_run=true` mutates the store and turns would-be victims into cache misses.
clear_partials` unlinks every file in `incoming`, including in-flight `BlobWriter` temps still being fetched; the later `rename` in `commit` then fails with ENOENT and the download is lost.
values()` emits `sweep_bytes_reclaimed` then `sweep_blobs_removed`, but `COUNTERS` names them in the opposite order, so Prometheus scrapes swap the two series.
on-demand `sweep()` calls `Sweeper::sweep` directly and skips the `running` mutex that `run()` holds, so a manual sweep can race the background sweeper and over-delete.
the full filesystem walk/`unlink` pass runs inline on the async worker (admin handler and `run()` after `lock`), so a large store stalls the runtime and other requests for the whole sweep.
tokio::time::interval` fires its first tick immediately, so the process sweeps on startup contrary to the “first tick is one interval away” guarantee in the comment above.
a failed `remove_file` is only logged; the blob is still counted as reclaimed and its digest is still passed to `forget()`, dropping index entries while the bytes may remain on disk.
