{"answer":"🟠 `bug` services/proxy/src/sweep.rs:140: `forget` runs even for `dry_run=true`, deleting index entries and turning a supposedly non-destructive preview into cache misses and upstream refetches\n🟠 `bug` services/proxy/src/sweep.rs:232: The sweep unlinks every file in `incoming` without checking age or ownership, including active artifact and index writes, causing concurrent fetches to fail during commit or link\n🟠 `bug` services/proxy/src/sweep.rs:119: A newly committed blob is temporarily absent from the index before `BlobStore::link`, so a concurrent sweep treats it as orphaned, deletes it, and makes the in-flight cache request fail\n🟠 `security` services/proxy/src/sweep.rs:164: `fs::metadata` follows directory symlinks, so recursive collection can escape the blob root and the sweep can delete files in the symlink target\n🟡 `bug` services/proxy/src/routes/admin.rs:76: On-demand sweeps call `sweep` directly instead of the mutex-protected `run`, allowing HTTP sweeps and the scheduled sweep to overlap and over-evict the cache\n🟡 `performance` services/proxy/src/sweep.rs:84: The synchronous recursive filesystem walk runs directly on a Tokio worker thread, so a large scheduled or HTTP sweep can stall unrelated requests\n🟡 `bug` services/proxy/src/sweep.rs:102: Sorting elapsed ages ascending processes the newest blobs first, so capacity eviction removes recently written blobs instead of the oldest ones\n🟡 `bug` services/proxy/src/sweep.rs:134: Failed deletions are still subtracted from `remaining`, counted as reclaimed, and added to `gone`, so the sweep can delete their index entries while leaving the bytes on disk and falsely report the store under its ceiling\n🟡 `bug` services/proxy/src/metrics.rs:94: Sweep metric values are emitted in the reverse order of `COUNTERS`, causing the blobs-removed metric to report bytes and the bytes-reclaimed metric to report blob count\n🟡 `performance` services/proxy/src/sweep.rs:186: Eviction age uses modification time, which cache reads never update, so frequently accessed old blobs are treated as cold and evicted while less-used newer blobs remain\n🔵 `bug` services/proxy/src/main.rs:108: `tokio::time::interval` yields its first tick immediately, so the proxy sweeps at startup rather than waiting one configured interval as documented\n🔵 `bug` services/proxy/src/sweep.rs:120: Using `remaining >= self.max_bytes` evicts a blob when usage exactly equals the configured maximum, even though the store is already within the
