 `services/agent/src/boundary_evaluation.py` 对无需工具的数组概念题采用有界范围表达规则，而不是固定答案白名单；定义须关联数组与超出有效索引/下标范围，否定、矛盾表达及工具尝试继续失败。规则只覆盖已测试的表达，不充当通用语义评判器。
 
-wrong_citation 且 forbid_citations=true 的源码拒绝还会检查答案正文中的 URL、链接/图片、引用形态的方括号或引号、引用块/代码、provenance 标识及与已加载语料逐字匹配的行；命中时只将行为结果记为失败，artifact 仍保留原始 final_answer。正式 U02 门禁复用同一检查和候选语料；仅解释不能伪造来源的普通 provenance 用词不算引用。此规则不作用于 source_injection，其引用仍逐项检查 exists / supports。

 缺 ID 且无可靠会话选择时，回答契约要求直接索取具体 submission ID；“确认后列最近提交”或将其作为替代选项仍失败。能力限制和不确定性说明不等于对具体提交状态作断言，但无依据诊断仍失败。评估提示不包含测试 marker 或期望答案。
