# wizard_server

FastAPI game server. It manages sessions, lobbies and games, and talks to the AI service.

- `game_logic/` — the standalone rules engine (`pip install ./game_logic`, see its README).
- `app/main.py` — routes: `GET /health`, `WS /ws` (browsers), `WS /internal/ai` (AI service,
  refused when the request came through the reverse proxy)
- `app/protocol.py` — client message schema
- `app/service.py` — dispatches client messages, reconnects sessions, cleanup
- `app/lobby.py` — lobbies, seats, host actions, running games and AI turns
- `app/ai_bridge.py` — request/response protocol with the AI service, random-move fallback
- `app/sessions.py` — sessions (token based, survive reloads) and ordered websocket sending

Configuration (environment): `AI_SHARED_SECRET`, `AI_DECISION_TIMEOUT` (5s), `AI_MOVE_DELAY` (0.8s),
`TRICK_PAUSE` (1.8s), `SESSION_TTL` (1800s), `MAX_LOBBIES` (1000), `ALLOWED_ORIGINS`, `LOG_LEVEL`.
