PhysFixBench · PhyGround-91 + VideoPhy2-100 + PhyGround 第二批-100（draft v1，待人工审核）
291 条带物理缺陷的生成视频及结构化中文修复标注（fixing prompts），用于物理视频修复（physics video correction）的基准构建。格式与 PhysFixBench · Physion-300 相同：同样的 jsonl / csv 字段、同样的修复指令写法、同样的人工审核页。本包为 draft 版本，所有标注等待人工审核（pass / edit / reject）。
数据来源与质控
- PhyGround（91 条）：PhyGround 人工评测（剔除未过质检的标注者，每条视频取各标注者均分）中，语义对齐 SA ≥ 3.5、至少一条物理定律均分 ≤ 2.5、且并非所有定律都低（整体崩坏不收）的视频。覆盖 8 个生成模型。
- VideoPhy2（100 条）：VideoPhy2 test 集中 SA ≥ 4、物理常识 PC ≤ 3、标注者至少写了一条违反的物理规则的视频；去掉分辨率低的 VideoCrafter。同一 prompt 只留排名最高的一条；与 PhyGround 名单 prompt 重复的，排在同票数的其他视频之后。
- GPT-5.5 逐帧核实：每条候选按 4 fps 抽帧并标时间戳，连同生成 prompt 和人工标签交给 GPT-5.5。人工标签（PhyGround 的低分定律；VideoPhy2 的违反规则原句）逐条当作待核实的说法，判 supported / not_supported（VideoPhy2 另有 not_in_video，用来识别讲的东西视频里根本没有的标注噪声），并写出缺陷时间段、描述、修复指令和需保持的内容；或者给出拒收理由：无物理错误、只有语义问题、原标注误报、整体崩坏、画质差、不可修。
- 三遍投票：单次调用不稳定，每条跑三遍，按保留票数排序，同票数再按平均严重度、平均置信度排序。三遍都保留的记为 confident，否则记为 borderline。至少一票保留才进名单。票数不代表判对，所以每一条都需要人工审。
- PhyGround 第二批（100 条）：第一批不足 100 条，于是放宽阈值补选：SA ≥ 3.0、至少一条定律均分 ≤ 3.0、并非所有定律都低，去掉第一批已核实过的 149 条候选，剩 302 条。核实流程、提示词、抽帧和投票规则与第一批相同，但核实模型换成了 gpt-6-astra（通过 Codex CLI 调用，reasoning effort medium），因为 GPT-5.5 接口不可用。302 条中至少一票保留的有 111 条，按票数取前 100（三遍都保留 79 · 边界 21）；与第一批 prompt 重复的（同一 prompt 的其他生成模型视频）排在同票数视频之后，最终有 37 条。
- 两个核实模型的差异：在第一批 149 条候选上让 gpt-6-astra 单跑一遍对照。它明显更严：单遍保留率 29%，GPT-5.5 约 46%；GPT-5.5 三遍都保留的 51 条里，它只保留 24 条。单遍结论一致率 93/149，GPT-5.5 自身两遍之间是 126/149。gpt-6-astra 更紧扣人工标出的定律，人工没标、但画面上很明显的错误（如物体凭空出现）它可能放过。所以两批的票数、严重度不能直接跨批比较，
phyground_b2里gpt_*字段都是 gpt-6-astra 的结论。 - 中文修复标注：「问题 / 正确表现 / 保持不变」三段和四个分类标签（
error_family/interaction_primitive/scenario_domain/review_error_category）由 Claude 根据 GPT-5.5 的英文错误描述、修复指令、保持内容和生成 prompt 改写、归类，Claude 没有看视频，准确度以 GPT-5.5 的英文为上限。每条问题的时间段直接沿用 GPT-5.5 给的（4 fps 精度，所以有 0.25s 级的值）。英文原文保存在error_description_en/correction_instruction_en/protected_content_en中。
