 - 在线 `GET /internal/v1/dispatcher/tasks?after=<watermark-or-current_cursor>` 返回 `schema_version=task-discovery.v0.4-proposal`、`mode=changes`、`dispatcher_id`、`tasks[]` 和 `next_cursor`。非空页严格前进，空页等于本次请求游标；SaaS 保证每 D 事件连续、分页完整、有序、不得提前丢失未消费增量，无法满足即显式报错并关闭新执行、重新全量。HTTP 400 不合法请求、403 D 无归属、503 服务不可用；错误响应严格见 Schema，**不复用** v0.2 `changes[]`/410。具体身份验证仍按现有只读 HTTP 配置合同。
 - **仅在本次进程运行期间**按发现水位定时查询增量，用于新增任务归属、撤销/退役和必要身份校验。水位不是最大 task_id；异常页/缺页不得推进游标或视为空变更。重启重新全量，不要求从上一次进程的永久事件游标续读；旧 v0.3 的 `after=0` 事件回放和 SQLite 持久游标不得被当作新全量响应。
 - 任务列表的任务状态可以作为启动快照的初始状态及增量身份/一致性校验，**运行中 pause/resume/stop 由独立 MQ 控制队列生效**；增量页 `running` 不能自动解除暂停或不可逆停止。若列表状态与已应用的 MQ 控制矛盾，关闭该任务新接纳并报错、等待受控恢复，不按 HTTP 到达顺序偷偷切换状态。`GET /internal/v1/dispatcher/task/:task_id` 的授权配置和 resume 的新鲜状态核验仍保留，不等同于恢复“发现页控制状态”机制。
