Thoughts

Open Brain Session 13 - Built action item tracking with auto-resolution. New action_items table tracks open/resolved status across all capture paths. When a new thought comes in, gpt-4o-mini checks it against open items and auto-closes matches. Digest upgraded from gpt-4o-mini to Claude Sonnet via OpenRouter for better narrative synthesis. Backfilled 384 items from thought metadata, cleaned down to 26 genuine open items. Gmail bridge spam contamination identified as root cause of most noise. "done:" Slack command available as manual fallback.
