Summary

TranscriptsStore.readUtterancesFromDir in src/transcripts/store.ts creates createReadStream and readline.createInterface for streaming JSONL parsing, but does not clean them up after use. If JSON.parse throws inside the async iteration loop, the underlying file descriptor remains open.

Reproduction

Source inspection: lines 199-201 create createReadStream and createInterface without lines.close() or stream.destroy() on error exit.

Expected

Wrap the for await loop in try/finally that calls lines.close() and stream.destroy().

Scope

src/transcripts/store.ts:199-232 — 1 file, ~6 LoC change.
