{"answer":"🟠 bug services/proxy/src/sweep.rs:137,140: Dry runs still pass the populated `gone` list to `forget`, deleting index entries even though the blobs were not removed; `?dry_run=true` therefore changes cache behavior and causes subsequent requests to refetch.\n🟠 bug services/proxy/src/sweep.rs:232: The sweep deletes every file in `incoming` without distinguishing active writers from abandoned partials, so an in-flight fetch can have its temporary file unlinked and then fail at `BlobWriter::commit`.\n🟠 bug services/proxy/src/sweep.rs:119: A newly committed blob has no index entry until the later link operation, so the sweep can delete it in that window and make the current fetch fail when it reopens the committed blob.\n🟠 bug services/proxy/src/routes/admin.rs:76: The synchronous sweep bypasses `Sweeper::running`, allowing concurrent admin sweeps and overlap with the background sweep, which can produce conflicting scans and over-eviction.\n🟠 performance services/proxy/src/routes/admin.rs:76: The full synchronous filesystem walk and index read run directly on a Tokio request worker, so a large cache or concurrent sweep requests can block unrelated proxy traffic.\n🟡 bug services/proxy/src/metrics.rs:94: The values place reclaimed bytes before removed blobs, while `COUNTERS` declares blobs before bytes, causing both sweep Prometheus metrics to report the other counter's value.\n🟡 bug services/proxy/src/sweep.rs:120: Using `remaining >= max_bytes` evicts an eligible old blob even when the store is exactly at its configured ceiling, unnecessarily shrinking the cache on every sweep at that boundary.\n🔵 bug services/proxy/src/main.rs:108: `tokio::time::interval` fires its first tick immediately, contrary to the comment and intended behavior, so a proxy sweeps the cache during startup instead of waiting for the configured interval.","auth":{"mode":"api_key"},"effort":"high","elapsed_secs":190.786,"error":null,"error_kind":null,"instructions":[],"model":"openai/gpt-5.6-luna","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-E9MnUY/.git","/private/var/folders/d1/tvmyp5cs1gz38rltf390ddpw0000gn/T/benchee-agent-E9MnUY/.afi","/private/var/folders/d1/tvmyp5cs1gz38rltf390ddpw0000gn/T/benchee-agent-E9MnUY/.agents","/private/var/folders/d1/tvmyp5cs1gz38rltf390ddpw0000gn/T/benchee-agent-E9MnUY/.codex","/private/var/folders/d1/tvmyp5cs1gz38rltf390ddpw0000gn/T/benchee-agent-E9MnUY/AGENTS.md","/private/var/folders/d1/tvmyp5cs1gz38rltf390ddpw0000gn/T/benchee-agent-E9MnUY/CLAUDE.md"],"readable_paths":["/"],"readable_roots":["/private/var/folders/d1/tvmyp5cs1gz38rltf390ddpw0000gn/T/benchee-agent-E9MnUY","/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-Fuey47"]},"schema_version":1,"source":"openrouter","sources":[{"auth":{"mode":"api_key"},"source":"openrouter","usage":{"cache_read_tokens":237890,"cache_write_tokens":56812,"cost_usd":0.038748,"estimated_tokens":0,"input_tokens":21,"output_tokens":1406,"reasoning_tokens":15080,"requests":7,"total_tokens":311209}}],"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":0.038748,"stopped":false},"cache_read_tokens":237890,"cache_write_tokens":56812,"cost_usd":0.038748,"estimated_tokens":0,"input_tokens":21,"output_tokens":1406,"reasoning_tokens":15080,"refused_by_approval":0,"refused_by_policy":0,"refused_tool_calls":0,"requests":7,"total_tokens":311209}}
