  "inputs/states/index.json 的 logs 为空，oracle.json 也标明 has_state_log=false：所有 when、never 与 success 均为 null，现有证据不能核验毫米级插接、各子步失败或速度阈值；atoms 中列出的 checker 输出只是待记录来源，并非声称已有日志字段（暂行：DECISIONS.md P8）。",
  "按文本分为横撑插入下框和装上对侧框两个步骤；四个原生阶段中的两次提离桌面是插接途中的运动与顺序验收，不另建拿起节点。一次装框产生四个上端接口，不按孔拆成四步；下框三根预装杆是保护约束，不是新插入步骤（DECISIONS.md S1、S2、S8、S10）。",
  "全体六件零件离手和低速连续 50 控制步跨越两个插接步骤，放在全局 success 的自然语言定义，两个节点只检查各自的插接结果，均允许持握成立并设置 freeze_held=false；下框三根既有接口的最终严格插好条件也由全局完整装配验收覆盖，避免重复的目标节点。没有日志，不能把这些条件写成可执行表达式。",
  "privileged 评分需两次独立动作回放均成功且最终状态哈希一致（inputs/grader/efe_dexhand-files/privileged/tests/grade.py:113-124）；standard 采用可信服务的现场成功记录（inputs/grader/efe_dexhand-files/standard/tests/grade.py:22-29）。两模式 checker.py、runtime.py 内容及任务参数完全一致，DAG 建模共同世界状态，不把交付有效性或哈希一致性编成语义条件。",
  "成功视频是总览视角，播放字幕为 2.4 倍速，结尾追加约 2 s 静帧；仿真中的 50 控制步不能当作视频上的 1 s。手在最终图像里仍靠近上框，不能把距离近误判成接触，字幕 released hold 50/50 支持已离手；几何细差依靠评分器判据，视频本身不能精确量出（DECISIONS.md N8）。",
  "文本约 10°/20° 的实际代码阈值分别是 0.1745/0.349 rad；判据采用代码原值，没有调节到该成功视频。任务的 6000 控制步上限属于回合预算，不作为 DAG 约束（DECISIONS.md P21）。"
