* perf(usage): keep per-source usage caches off the main thread The usage stores kept every provider's per-source scan cache (processedFiles / processedDatabases) inside the one JSON file main loads at startup. On a large Claude history that file is 56 MB, 43 MB of it per-source records only a scan reads, so main paid a sync read+parse at launch, a structured clone of the whole cache to and from the scan worker on every scan, and a pretty-printed rewrite after every scan. The usage scan worker now owns those records in a sidecar (`<cache>-sources.json`): it reads it before a scan, writes it after (compact, durable rename), and returns only sessions and daily aggregates. Main keeps and writes only that report, compact. A cache still carrying inline records is split on the worker the first time it is loaded (above 8 MB); smaller ones parse on main and rescan cold. Sync IPC getters and automation lookups wait for the load. Synthetic 56 MB cache, same machine, interleaved runs: - first launch: 108 ms sync parse -> 18 ms main busy, 4 ms longest block - later launches: ~69 ms -> ~7 ms - forced scan, longest main-thread block: 89 ms -> 11 ms (real built app, headless: 84-94 ms -> 11-13 ms) Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(usage): preserve cache attribution and legacy warm scans * fix(usage): reclaim cache temps after worker retirement --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> Co-authored-by: Neil <neil@stably.ai>

// Why: v4 reads OpenCode 2's `session_v2` table; v3 caches miss every v2 session.
|
|
// v5 merges a migrated session's two rows per column instead of picking one, so
|
|
// v4 caches hold zeroed costs and pre-migration metadata.
|
|
// v6 normalizes input; v7 preserves writes separately for telemetry.
