Second Brain: How to capture conversations

Discussed how to add conversations to Second Brain.

**Options:**
1. Bob inserts manually via Supabase API (simplest, works now)
2. OpenClaw cron job for automation (recommended next step)
3. Webhook endpoint (overkill for now)

**Decision:** Start with manual insertion, build cron automation later.

**Raw exchange:**
- Henry: "How would you add our conversations to second brain? Is it an API call?"
- Bob: Explained 3 options, recommended manual then cron
- Henry: "Yes. Save it."
