{"answer":"🟠 `bug` services/proxy/src/sweep.rs:232: Every file in `incoming` is deleted, including active `BlobWriter` temporary files; a sweep during a download unlinks its temp path so `commit` fails and the client request fails.\n\n🟠 `bug` services/proxy/src/sweep.rs:119: A blob committed before its index entry is linked is treated as unreferenced and deleted regardless of `min_age`; the normal fetch path has this window while registering upstream metadata, causing the request to fail or leave a newly linked cache entry pointing to a missing blob.\n\n🟡 `bug` services/proxy/src/sweep.rs:102: Sorting `Duration` ascending processes the youngest candidates first, not the oldest as intended, so eviction preferentially discards recently cached eligible artifacts.\n\n🟡 `performance` services/proxy/src/routes/admin.rs:76: The request handler runs the full synchronous filesystem sweep on a Tokio worker thread; sweeping a large cache blocks that executor worker from serving unrelated requests for the duration.\n\n🟡 `bug` services/proxy/src/metrics.rs:94: `values()` returns reclaimed bytes before removed-blob count, while `COUNTERS` declares the opposite order, so the two exported sweep metrics report each other’s values.\n\n🔵 `bug` services/proxy/src/main.rs:108: `tokio::time::interval` delivers its first tick immediately, so the advertised one-interval startup delay is not implemented and a restart can sweep an existing cache immediately.","auth":{"mode":"api_key"},"effort":"high","elapsed_secs":178.481,"error":null,"error_kind":null,"instructions":[],"model":"openai/gpt-5.6-terra","ok":true,"sandbox":{"backend":"macOS Seatbelt","denied_read_roots":["/Users/bart.smykla@konghq.com/Projects/github.com/smykla-skalski/benchee/subjects"],"environment":["HOME","LANG","LC_ALL","PATH","TERM","TMPDIR"],"mode":"read-only","network":"denied","protected_write_roots":["/private/var/folders/d1/tvmyp5cs1gz38rltf390ddpw0000gn/T/benchee-agent-ebxqft/.git","/private/var/folders/d1/tvmyp5cs1gz38rltf390ddpw0000gn/T/benchee-agent-ebxqft/.afi","/private/var/folders/d1/tvmyp5cs1gz38rltf390ddpw0000gn/T/benchee-agent-ebxqft/.agents","/private/var/folders/d1/tvmyp5cs1gz38rltf390ddpw0000gn/T/benchee-agent-ebxqft/.codex","/private/var/folders/d1/tvmyp5cs1gz38rltf390ddpw0000gn/T/benchee-agent-ebxqft/AGENTS.md","/private/var/folders/d1/tvmyp5cs1gz38rltf390ddpw0000gn/T/benchee-agent-ebxqft/CLAUDE.md"],"readable_paths":["/"],"readable_roots":["/private/var/folders/d1/tvmyp5cs1gz38rltf390ddpw0000gn/T/benchee-agent-ebxqft","/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-dDG7yA"]},"schema_version":1,"source":"openrouter","sources":[{"auth":{"mode":"api_key"},"source":"openrouter","usage":{"cache_read_tokens":97414,"cache_write_tokens":43478,"cost_usd":0.265164,"estimated_tokens":0,"input_tokens":15,"output_tokens":1435,"reasoning_tokens":9978,"requests":5,"total_tokens":152320}}],"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":8.0,"soft_ratio":0.8,"spent_usd":0.265164,"stopped":false},"cache_read_tokens":97414,"cache_write_tokens":43478,"cost_usd":0.265164,"estimated_tokens":0,"input_tokens":15,"output_tokens":1435,"reasoning_tokens":9978,"refused_by_approval":0,"refused_by_policy":0,"refused_tool_calls":0,"requests":5,"total_tokens":152320}}
