         BACKFILL 单片不超过一天。RETRY 使用 taskNo 和非空 reason 恢复原分仓逻辑任务，
         保留半归并屏障及旧尝试，拒绝验证会话复活、账号共享任务伪装单仓、有效执行租约及上游未齐；
         requestKey 同键异载荷拒绝。成功受理只表示排队，不表示采集或发布成功。
+        WAREHOUSE_DISCOVERY 仅允许 VALIDATION，只接受 requestKey/action，不要求已知仓码；
+        真实账号根最多一页10条、一次HTTP、60秒，读取后SAMPLE_DONE，不进入出库、详情、库存或正式发布。
+        普通 VALIDATION 冻结命令指定的单仓，每根独立最多300秒/40HTTP，账号预算、冷却与间隔仍共享。
