{"answer":"Here are the line-level defects:\n\n🔴 `bug` services/proxy/src/sweep.rs:224: `clear_partials` deletes every file in `incoming` with no age/ownership check, so a sweep mid-fetch removes live `BlobWriter` temps and the later `rename` in `commit` fails\n🔴 `bug` services/proxy/src/sweep.rs:102: `sort_by_key(|c| c.age)` orders youngest first, but eviction assumes oldest first—over-ceiling sweeps remove newly eligible blobs and keep the coldest ones\n🔴 `bug` services/proxy/src/sweep.rs:140: `forget` always deletes index entries for would-be victims, so `dry_run=true` still unlinks index files and turns hits into misses\n🟠 `bug` services/proxy/src/routes/admin.rs:76: admin calls `sweep` directly and skips `running`, so on-demand and background sweeps can run together and over-delete past the ceiling\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 swapped figures\n🟠 `bug` services/proxy/src/sweep.rs:126: a failed `remove_file` still counts the blob toward `removed`/`bytes` and still pushes it to `gone`, so index entries are dropped and metrics report space that was not reclaimed\n🟠 `perf` services/proxy/src/sweep.rs:84: the full filesystem walk runs inline on the async worker (also via `admin`’s sync `reclaim`), so a large store stalls the runtime until the sweep finishes\n🟡 `bug` services/proxy/src/sweep.rs:164: comment claims symlink size is the link size, but `fs::metadata` follows links and counts the target, so shared/symlinked blobs inflate `held` and trigger excess eviction","auth":{"mode":"api_key"},"effort":"high","elapsed_secs":107.85,"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-SnPyOA"]},"schema_version":1,"source":"openrouter","sources":[{"auth":{"mode":"api_key"},"source":"openrouter","usage":{"cache_read_tokens":85120,"cache_write_tokens":0,"cost_usd":0.157464,"estimated_tokens":0,"input_tokens":48852,"output_tokens":964,"reasoning_tokens":4740,"requests":5,"total_tokens":139676}}],"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":0.157464,"stopped":false},"cache_read_tokens":85120,"cache_write_tokens":0,"cost_usd":0.157464,"estimated_tokens":0,"input_tokens":48852,"output_tokens":964,"reasoning_tokens":4740,"refused_by_approval":0,"refused_by_policy":0,"refused_tool_calls":0,"requests":5,"total_tokens":139676}}
