Version: 0.9.70.dev.260504

后端：
1. 阶段 5 schedule 首刀服务化落地，新增 `cmd/schedule`、`services/schedule/{dao,rpc,sv,core}`、`gateway/client/schedule`、`shared/contracts/schedule` 和 schedule port
2. gateway `/api/v1/schedule/*` 切到 schedule zrpc client，HTTP 门面只保留鉴权、参数绑定、超时和轻量转发
3. active-scheduler 的 schedule facts、feedback 和 confirm apply 改为调用 schedule RPC adapter，减少对 `schedule_events`、`schedules`、`task_classes`、`task_items` 的跨域 DB 依赖
4. 单体聊天主动调度 rerun 的 schedule 读写链路切到 schedule RPC，迁移期仅保留 task facts 直读 Gorm
5. 为 schedule zrpc 补充 `Ping` 启动健康检查，并在 gateway client 与 active-scheduler adapter 初始化时校验服务可用
6. `cmd/schedule` 独立初始化 DB / Redis，只 AutoMigrate schedule 自有表，并显式检查迁移期 task / task-class 依赖表
7. 更新 active-scheduler 依赖表检查和 preview confirm apply 抽象，保留旧 Gorm 实现作为迁移期回退路径
8. 补充 `schedule.rpc` 示例配置和 schedule HTTP RPC 超时配置

文档：
1. 更新微服务迁移计划，将阶段 5 schedule 首刀进展、当前切流点、旧实现保留范围和 active-scheduler DB 依赖收缩情况写入基线

 ### 4.9 阶段 5：再拆 schedule / task / course / task-class
 
+当前进展（2026-05-04 首刀）：
+
+1. `schedule` 已开始服务化：新增 `cmd/schedule`、`services/schedule/{dao,rpc,sv,core}`、`gateway/client/schedule`、`shared/contracts/schedule` 和 `shared/ports` schedule port。
+2. gateway 的 `/api/v1/schedule/*` HTTP 门面已切到 schedule zrpc client；gateway 不再通过 `backend/service.ScheduleService` 直接承载 schedule HTTP 入口业务。
+3. active-scheduler 的 schedule facts / feedback / confirm apply 已改为调用 schedule RPC adapter；`cmd/active-scheduler` 启动依赖检查已移除 `schedule_events`、`schedules`、`task_classes`、`task_items`，迁移期仍直接读取 `tasks`。
+4. gateway schedule client 和 active-scheduler schedule RPC adapter 已接入 `Ping` 启动期健康检查；单体聊天主动调度 rerun 的 schedule facts / feedback / apply 也已切到 schedule RPC，task facts 暂时仍走 Gorm。
+5. 旧实现仍保留：`backend/service/schedule.go`、`backend/dao/schedule.go`、active-scheduler 旧 Gorm apply adapter 暂时保留，用于 agent 迁移期、单体残留路径和回退。
+6. 当前切流点：HTTP schedule 流量进入 `cmd/schedule`；active-scheduler 正式写日程进入 schedule 服务；course / task-class / agent 内部仍存在直接 DAO 调用，后续按域继续切。
+
 目标：
 
 1. 把正式日程和任务池的所有权拆出去。
