{"answer":"🔴 `bug` services/proxy/src/sweep.rs:140: `forget(&index, &gone)` runs unconditionally, so a `dry_run=true` sweep deletes the index entries for every referenced blob it marks for age eviction even though the blob bytes are left in place. `dry_run` is documented (docs/architecture.md, operations.md) as reporting what a sweep would reclaim \"without removing anything\"; instead it orphans blobs, forcing refetches and leaving the bytes to be deleted by the next real sweep.\n🟠 `bug` services/proxy/src/routes/admin.rs:76: the on-demand route calls `app.sweeper.sweep(dry_run)` directly, bypassing the `running` `Mutex` that only `Sweeper::run` (sweep.rs:82-84) acquires. Two concurrent sweep requests — or a sweep request racing the background tick — both walk the same total and both remove the oldest blobs, taking the store well below the ceiling, the exact over-eviction the module's \"one sweep at a time\" promise (sweep.rs:10-12) exists to prevent.\n🟡 `bug` services/proxy/src/sweep.rs:164: `fs::metadata` follows symlinks and returns the *target's* size, contradicting the comment on lines 160-163 which claims a link is counted at the size of the link. For a store whose blobs are symlinked in (the \"often\" case the comment names), `held` and `bytes` are inflated by the target size, so the ceiling accounting and the reclaimed-bytes counter are both wrong; `fs::symlink_metadata` is what the comment describes.\n🔵 `performance` services/proxy/src/sweep.rs:84: `run` is `async` but calls the fully synchronous `sweep`, which does `readdir`/`read`/`remove_file` across tens of thousands of leaf directories directly on the tokio worker thread (the route at admin.rs:76 does the same). A sweep the code itself says can take longer than ten seconds blocks an executor worker for that whole span, stalling every other request pinned to it; the synchronous walk belongs in `spawn_blocking`.","auth":{"mode":"api_key"},"effort":"high","elapsed_secs":68.06,"error":null,"error_kind":null,"instructions":[],"model":"z-ai/glm-5.2","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-9goG5c"]},"schema_version":1,"source":"openrouter","sources":[{"auth":{"mode":"api_key"},"source":"openrouter","usage":{"cache_read_tokens":160896,"cache_write_tokens":0,"cost_usd":0.137661,"estimated_tokens":0,"input_tokens":30269,"output_tokens":724,"reasoning_tokens":11424,"requests":7,"total_tokens":203313}}],"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":0.137661,"stopped":false},"cache_read_tokens":160896,"cache_write_tokens":0,"cost_usd":0.137661,"estimated_tokens":0,"input_tokens":30269,"output_tokens":724,"reasoning_tokens":11424,"refused_by_approval":0,"refused_by_policy":0,"refused_tool_calls":0,"requests":7,"total_tokens":203313}}
