- **Threads API:** Returns 6 threads (24h window), 8 threads (7d window) with correct metadata (session file, tokens, cost)
- **Session tails:** Returns last 5 log entries, gracefully handles missing files
- **Linear issues:** 74 issues loaded from tasks-index.json, 21 active
- **Thread attachments:** 83 attachments in Redis, create/read working
- **Thread mutations:** update-thread, delete-thread, sync-linear all responding correctly

No fixes were needed. Everything passed.
