ama_bench

AMA-Bench dataset loader.

Reference dataset: https://huggingface.co/datasets/AMA-bench/AMA-bench

Paper: https://arxiv.org/abs/2602.22769

This implementation follows the published schema with fields like: - episode_id - task / task_type / domain / source / success / num_turns / total_tokens - trajectory: list[{turn_idx, action, observation}] - qa_pairs: list[{question, answer, question_uuid, type}]

Evaluation protocol follows the paper's long-context baseline: pack the trajectory into the model input, reserving space for the question and answer. When a trajectory exceeds the budget, truncation preserves the first 50% and last 50% of the token budget (matching Appendix B of the paper).
