"""
Training utilities for the CounterFeint Investigator.

The training notebook (``train_investigator.ipynb``) imports everything
it needs from this package, keeping the notebook to thin orchestration
cells.

Modules:

  * :mod:`.rollout`      — episode-collection helpers (entry point:
                           :func:`.rollout.collect_dataset`).
  * :mod:`.proxy_reward` — verifiable per-completion reward function
                           used by ``GRPOTrainer`` (entry point:
                           :func:`.proxy_reward.make_proxy_reward_fn`).
