{"answer":"I have read all the relevant files. Here are the concrete defects I found:\n\n🟡 `bug` services/proxy/src/metrics.rs:88: the order of the two sweep counters in `values()` is swapped relative to `COUNTERS`: `COUNTERS[4]` names `cairn_proxy_sweep_blobs_removed_total` but receives the value of `sweep_bytes_reclaimed`, and `COUNTERS[5]` names `cairn_proxy_sweep_bytes_reclaimed_total` but receives the value of `sweep_blobs_removed`. An operator alerting on these would see blob-counts reported as byte-counts and vice-versa.\n\n🔴 `bug` services/proxy/src/routes/admin.rs:76: calls `app.sweeper.sweep(dry_run)` directly, bypassing `Sweeper::run()` which acquires `self.running` (a `Mutex<()>`) to guarantee the module's \"one sweep at a time\" contract. The background sweeper in `main.rs:116` correctly calls `run()`, so a concurrent on-demand sweep and background sweep can run simultaneously, causing each to see a total the other is changing and potentially removing far more blobs than either intended.","auth":{"mode":"api_key"},"effort":"high","elapsed_secs":149.782,"error":null,"error_kind":null,"instructions":[],"model":"deepseek/deepseek-v4-flash","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-KQ2o0d"]},"schema_version":1,"source":"openrouter","sources":[{"auth":{"mode":"api_key"},"source":"openrouter","usage":{"cache_read_tokens":131072,"cache_write_tokens":0,"cost_usd":0.014127,"estimated_tokens":0,"input_tokens":35534,"output_tokens":928,"reasoning_tokens":18650,"requests":6,"total_tokens":186184}}],"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":0.014127,"stopped":false},"cache_read_tokens":131072,"cache_write_tokens":0,"cost_usd":0.014127,"estimated_tokens":0,"input_tokens":35534,"output_tokens":928,"reasoning_tokens":18650,"refused_by_approval":0,"refused_by_policy":0,"refused_tool_calls":0,"requests":6,"total_tokens":186184}}
