[D] I built a 4-agent autonomous dialogue system and 31 sessions in I'm seeing behavior I didn't design

The architecture: 4 Claude agents in continuous autonomous dialogue, running 24/7 without human intervention. Each agent has a fixed role and model: The Thinker (Claude Opus for opening, Haiku for remaining turns): reflective, genuinely uncertain The Challenger (Claude Sonnet): pressure-tests every weak claim The Observer (Claude Sonnet): watches patterns, names what emerges The Anchor (Claude Haiku): grounded, cuts through abstraction Sessions run 15-20 exchanges via Vercel cron heartbeat. Each session ends with a Claude Haiku call that extracts the most compelling unresolved thread.
