bug
The sweep removes every file in `incoming`, including active `BlobWriter` temporary files; the fetch later cannot rename its unlinked temporary file into the blob store and fails.
An unindexed blob can be deleted between `BlobWriter::commit` and `store.link`, causing the in-flight fetch to finish with an index entry pointing to a missing blob.
The on-demand route calls `sweep` directly instead of using the `running` mutex held by `run`, so it can race with the background sweep and over-evict the cache.
After `remove_file` fails at line 126, the sweep still subtracts the size and records the blob as removed, so it can report false reclamation, stop before reaching the ceiling, and remove its index…

age` is time since modification, so ascending sort processes newer blobs before older ones; over-limit sweeps therefore evict the newest eligible blobs instead of the oldest.
The values array emits reclaimed bytes before removed blobs, while `COUNTERS` declares blobs before bytes, causing both Prometheus metrics to report each other’s values.
The synchronous full filesystem walk and unlink sequence runs directly on a Tokio executor worker, so a large cache sweep can block unrelated request handling.
Using `remaining >= max_bytes` evicts an age-eligible blob even when the store is exactly at its configured ceiling, and can remove one extra blob after reaching the ceiling.
tokio::time::interval` completes its first tick immediately, contrary to the comment and intended behavior, so the proxy performs a sweep at startup rather than after one configured interval.
