{"text":"It could be that the BufWriter is holding bytes in user space when fsync is called","expected":"hypothesis"}
{"text":"Looked at db.rs:133 — rebuild_state opens an unchecked_transaction and aborts on the first parse error","expected":"finding"}
{"text":"Confirmed in mcp/main.rs:158 — every tool handler calls full rebuild_state, never the incremental path","expected":"finding"}
{"text":"In storage.rs the JsonlWriter wraps File in fd_lock::RwLock and acquires write() per append","expected":"finding"}

{"text":"Bench result: rebuild_state_10k_events median 820ms, ingest_new_events 38ms — 21x faster","expected":"evidence"}
{"text":"Reproduced the corruption: two parallel hooks racing on the same JSONL on Windows produced 7 torn lines","expected":"evidence"}
{"text":"Going with fd-lock for the file lock — single API across Linux/macOS/Windows, well-maintained","expected":"decision"}
{"text":"We will return Result<Json<T>, McpError> from every tool handler instead of the success-typed envelope","expected":"decision"}

{"text":"Tried adding rwlock around index_event but it deadlocks with the open transaction — won't work","expected":"rejection"}

{"text":"PR merged. Released 0.1.4 to crates.io. Closing this task","expected":"close"}

{"text":"Maybe the problem is FTS5 not being a regular index; could be slow at 100k events","expected":"hypothesis"}

{"text":"e2e: ran full pipeline 50 times, p99 < 200ms, p50 < 50ms","expected":"evidence"}
