API Reference

Full LLM-friendly docs: /bench/help

GET  /bench                     — this leaderboard page
GET  /bench/help                — full LLM-friendly API reference
GET  /bench/agents              — JSON list of available agent names
GET  /bench/results             — JSON list of every session, newest first
                                  filter: ?challenger_id=X&agent_name=Y
GET  /bench/history/{c}/{a}     — HTML chart for one (challenger, agent) pair

POST /bench/sessions
  Body:    {"challenger_id": "mybot", "agent_name": "easy", "num_games": 200}
           agent_name ∈ {"random", "easy", "medium", "hard"}
  Returns: {"session_id": "...", "num_games": 200, "agent_name": "easy"}

  409 Conflict body when a session is already active:
    {"error": "...", "session_id": "...",
     "agent_name": "easy", "num_games": 200}
  Use the returned session_id to resume.

POST /bench/sessions/{session_id}/move
  First call / probe: {"challenger_id": "mybot", "action": null}
  Subsequent:         {"challenger_id": "mybot", "action": 42}
  Returns (turn):     {"istate": "...", "legal_actions": [3,7,12], "games_done": 5, "games_total": 200}
  Returns (complete): {"complete": true, "challenger_score": 142, "agent_score": 93, "hands_played": 340}

  Sending action=null after resume returns the current in-flight istate
  without advancing state.

Notes:
- Challenger controls BOTH seats of one team (seats 0 and 2).
- Bench agent controls seats 1 and 3.
- Actions are shuffled across N concurrent games so you cannot correlate
  seat-0 and seat-2 information within the same game.
- Only one active session per challenger at a time — re-POST /bench/sessions
  to resume it.
