"note": "Framework implementations lean judge-heavier than the official default: lmms-eval judges every sample (use_lmms_judge), VLMEvalKit EMMADataset inherits ImageShortQADataset's all-LLM binary judge (image_shortqa.py:15-48). Classified rule_llm_judge: deterministic extraction resolves direct letter/short answers (the published prompt requests direct answers), LLM resolves the remainder — consistent with official fast-eval + LLMs-eval pairing. EMMA is mixed MCQ/open (options optional); task_type multiple_choice as majority format (2002/2788 rows are Multiple Choice)."

"notes": "Tier 1: EMMA uses MMMU-style <image_N> markers in question/options; MCQ letter-answer convention. Re-conversion 2026-07-07: restored the options block data (options were dropped in the previous upload) and prepended '{% if context %}{{ context }}\\n{% endif %}' because the official build_query renders context before the question (57 Physics rows carry a non-empty context block of physical constants that the previous upload dropped). The direct-answer trailers are kept from the previously published template; the official EMMA eval prompt additionally requests \\boxed{} + CoT (configs/gpt.yaml) — intentional deviation preserved from the published copy."
