 - 派发后一单前用该回答重读它的选项与成本,⛔ 不沿用立单时那份。
 - 在飞卡衍生三分:不修它验收过不过;in-scope ⇒ 父卡 sub-issue,认领席自有、优先级继承。
 - 该 sub-issue 带父卡域与优先级直接派发,唯一绕过分诊;sweep 事后扫,重复关 `duplicate`。
+- 排队卡含他车道项 ⇒ 发现席自拆:新卡无 `domain:*`,首行 `carries item k of #N; #N keeps items …`。
+- 分诊首触定域可改判;拆出卡 ⛔ 不承父卡域(承域只及本车道 sub-issue),父卡余项照 `Fixes`。
 - 自在飞派发升级出的卡首行一句:本卡承哪一半、父卡留哪一半;缺此行不入队不入箱。
 - 分诊预见的后续工作是一张卡,触发条件落地时立卡;⛔ 分诊一句话永不授权无卡编辑。
 - 阻塞项无主 ⇒ 被挡席认领做掉,不限大小;在该卡走完整认领、尊重其热文件串行队。
