LLM-powered simulation of 20 diverse AI people living in a city.
Architecture: world (clock, city map, events), agents (persona, memory,
needs, relationships), actions (movement, activities, conversation, social),
engine (simulation loop, scheduler, entropy management, Claude API),
persistence (SQLite), and API server (FastAPI REST + WebSocket).
All 12 integration tests pass with mock LLM.
