auto-compress is on at 85% but the context window of "google/gemini-3.7-flash" on openrouter is unknown, so this run will not compress - set AFI_SOURCE_OPENROUTER_CONTEXT_WINDOW (or pass --context-window) to enable it

🔴 `bug` services/proxy/src/sweep.rs:102: candidates are sorted by age ascending rather than descending, causing sweeps to evict the newest blobs first instead of the oldest
🔴 `bug` services/proxy/src/metrics.rs:94: counter values for `sweep_bytes_reclaimed` and `sweep_blobs_removed` are swapped relative to their exposition declarations in `COUNTERS`, reporting byte totals under the blob count metric and vice versa
🟠 `bug` services/proxy/src/routes/admin.rs:76: admin sweep endpoint calls `app.sweeper.sweep` directly without acquiring `Sweeper::running`, allowing concurrent sweeps to run simultaneously against the one-sweep-at-a-time guarantee
