"""
CounterFeint — Multi-Agent Ad Fraud Investigation Environment for OpenEnv.

Round 2 introduces a three-agent FraudArena:

    Fraudster     proposes / mutates ads to sneak past review
    Investigator  investigates ads and renders verdicts
    Auditor       audits the trace post-hoc for miscalibration or gibberish

All three agents share one environment instance per match and interact via
WebSockets on role-specific routes (/ws/fraudster, /ws/investigator, /ws/auditor).

Example (three-agent):

    >>> from counterfeint import MatchClient, FraudsterAction
    >>> import asyncio
    >>> async def demo():
    ...     async with MatchClient("http://localhost:8000") as match:
    ...         await match.reset(seed=42, task_id="task_1")
    ...         await match.fraudster.step(FraudsterAction(
    ...             action_type="propose_ad",
    ...             ad_copy="Free iPhone - tap here!",
    ...             category="fake_giveaway",
    ...         ))
    ...         state = await match.state()
    ...         print(state.phase, state.grader_score)
    >>> asyncio.run(demo())

Example (single-agent legacy):

    >>> from counterfeint import AdFraudEnv, AdReviewAction
    >>> with AdFraudEnv(base_url="http://localhost:8000").sync() as env:
    ...     env.reset(seed=42, task_id="task_1")
