{"answer":"🔴 `bug` services/proxy/src/sweep.rs:140: `forget` always deletes index entries after the candidate loop, including when `dry_run` is true, so `POST .../sweep?dry_run=true` still unlinks index files and breaks the “without removing anything” contract.\n🔴 `bug` services/proxy/src/sweep.rs:102: `sort_by_key(|c| c.age)` orders ascending duration-since-mtime, so newest blobs are considered first; over-ceiling eviction deletes recent packages and keeps the oldest ones.\n🟠 `bug` services/proxy/src/metrics.rs:94: `values()` emits `sweep_bytes_reclaimed` then `sweep_blobs_removed`, but `COUNTERS` names them in the opposite order, so Prometheus scrapes swap blob-count and byte-total.\n🟠 `bug` services/proxy/src/sweep.rs:224: `clear_partials` unlinks every file under `incoming`, including live `BlobWriter` temps still being fetched, so an in-flight miss can lose its temp mid-write.\n🟠 `bug` services/proxy/src/routes/admin.rs:76: the admin path calls `sweeper.sweep` and never takes `running`, so it can run concurrently with `run()` and double-count/over-delete against the one-sweep-at-a-time guarantee.\n🟠 `bug` services/proxy/src/sweep.rs:90: `sweep` does blocking recursive FS I/O on the async worker (via `run` and the admin handler) with no `spawn_blocking`, so a large store stalls the proxy event loop.\n🟡 `bug` services/proxy/src/main.rs:115: `tokio::time::interval` fires its first tick immediately, so the process sweeps on startup despite the comment that the first pass waits one full interval.\n🟡 `bug` services/proxy/src/sweep.rs:126: a failed `remove_file` still increments `removed`/`bytes` and adds the digest to `gone`, so metrics over-report and `forget` drops index entries for blobs that are still on disk.\n🟡 `bug` services/proxy/src/sweep.rs:185: eviction age uses `modified()` only; cache hits never refresh mtime, so frequently served old blobs look cold and are preferred for removal once the store is over ceiling.","auth":{"mode":"api_key"},"effort":"high","elapsed_secs":185.042,"error":null,"error_kind":null,"instructions":[],"model":"x-ai/grok-4.5","ok":true,"sandbox":{"backend":"macOS Seatbelt","denied_read_roots":[],"environment":["HOME","LANG","LC_ALL","PATH","TERM","TMPDIR"],"mode":"read-only","network":"denied","protected_write_roots":["/Users/bart.smykla@konghq.com/Projects/github.com/smykla-skalski/benchee/.git","/Users/bart.smykla@konghq.com/Projects/github.com/smykla-skalski/benchee/.afi","/Users/bart.smykla@konghq.com/Projects/github.com/smykla-skalski/benchee/.agents","/Users/bart.smykla@konghq.com/Projects/github.com/smykla-skalski/benchee/.codex","/Users/bart.smykla@konghq.com/Projects/github.com/smykla-skalski/benchee/AGENTS.md","/Users/bart.smykla@konghq.com/Projects/github.com/smykla-skalski/benchee/CLAUDE.md"],"readable_paths":["/"],"readable_roots":["/Users/bart.smykla@konghq.com/Projects/github.com/smykla-skalski/benchee","/Users/bart.smykla@konghq.com/Projects/github.com/smykla-skalski/benchee/.git","/bin","/sbin","/usr/bin","/usr/sbin","/usr/lib","/usr/libexec","/usr/share","/System/Library","/Library/Apple","/Library/Filesystems/NetFSPlugins","/Library/Preferences","/private/etc","/private/var/db/timezone","/private/var/db/DarwinDirectory/local/recordStore.data","/private/var/select/developer_dir","/private/var/select/sh","/opt/homebrew/bin","/opt/homebrew/Cellar","/opt/homebrew/etc/gitconfig","/opt/homebrew/lib","/opt/homebrew/opt","/usr/local/bin","/Applications/Xcode.app/Contents/Developer","/Applications/Xcode.app/Contents","/Users/bart.smykla@konghq.com/.local/bin/afi"],"writable_roots":["/private/var/folders/d1/tvmyp5cs1gz38rltf390ddpw0000gn/T/afi-sandbox-ij1Q4z"]},"schema_version":1,"source":"openrouter","sources":[{"auth":{"mode":"api_key"},"source":"openrouter","usage":{"cache_read_tokens":111616,"cache_write_tokens":0,"cost_usd":0.250513,"estimated_tokens":0,"input_tokens":79348,"output_tokens":1125,"reasoning_tokens":8597,"requests":6,"total_tokens":200686}}],"system_prompt":{"file":null,"mode":"builtin"},"tools":["read_file","write_file","edit_file","list_dir","search_files","glob_files","run_bash","wait_background"],"usage":{"budget":{"converged":false,"hard_ratio":0.95,"limit_usd":2.0,"soft_ratio":0.8,"spent_usd":0.250513,"stopped":false},"cache_read_tokens":111616,"cache_write_tokens":0,"cost_usd":0.250513,"estimated_tokens":0,"input_tokens":79348,"output_tokens":1125,"reasoning_tokens":8597,"refused_by_approval":0,"refused_by_policy":0,"refused_tool_calls":0,"requests":6,"total_tokens":200686}}
