/**
|
||||
* 任务批量动作执行 — 四类动作(推进/改状态、取消·暂缓·恢复、删除、改优先级/指派)。
|
||||
*
|
||||
* 设计:后端零改动,前端串行循环复用现有单条 taskApi(advance 自带 CAS + can_transition +
|
||||
* 父聚合 + review_rounds;delete 级联软删;update 白名单含 priority/assignee、禁 status)。
|
||||
* 合法性预判走 `TASK_STATUS_TRANSITIONS` 单一真相源(与 TaskDetail ADVANCE_MAP 同源),
|
||||
* 非法项记 skipped(不算失败),后端二次校验兜底(防御选中后外部改动)。
|
||||
*
|
||||
* 每个动作内置 busy 置位 + 结束后统一 onRefresh + toast 汇总;调用方拿返回的
|
||||
* BatchActionResult 可自行展示详情,toast 已自动处理。
