后端：
1. 日程暂存接口——前端拖拽调整后保存到 Redis 快照
  - api/agent.go：新增 SaveScheduleState handler，解析绝对时间格式请求体，3 秒超时保护
  - routers/routers.go：注册 POST /schedule-state
  - model/agent.go：新增 SaveScheduleStatePlacedItem / SaveScheduleStateRequest 结构体
  - respond/respond.go：新增 5 个排程状态错误码（40058~40062）
  - 新增 service/agentsvc/agent_schedule_state.go：Load 快照 → ApplyPlacedItems → Save 回 Redis，校验归属
  - 新增 newAgent/conv/schedule_state_apply.go：ApplyPlacedItems 绝对坐标→相对 day_index 转换，去重/坐标/嵌入关系校验
2. SchedulePersistor 持久化层全面下线
  - 删除 newAgent/conv/schedule_persist.go（280 行，DiffScheduleState → applyChange → 事务写库整条链路）
  - model/state_store.go：移除 SchedulePersistor 接口
  - model/graph_run_state.go / node/execute.go / node/agent_nodes.go / service/agent.go / service/agent_newagent.go /
  cmd/start.go：移除 SchedulePersistor 字段、参数、注入六处
3. schedule_completed 事件推送——deliver 节点排程完毕信号
  - model/common_state.go：新增 HasScheduleChanges 标记，ResetForNextRun 清理
  - node/execute.go / node/rough_build.go：写工具和粗排成功后置 HasScheduleChanges=true
  - node/deliver.go：IsCompleted && HasScheduleChanges 时调用 EmitScheduleCompleted
  - stream/emitter.go：新增 EmitScheduleCompleted 方法
  - stream/openai.go：新增 StreamExtraKindScheduleCompleted + NewScheduleCompletedExtra
4. 预览接口补全 task_class_id
  - model/agent.go：GetSchedulePlanPreviewResponse 新增 TaskClassIDs
  - model/schedule.go：HybridScheduleEntry 新增 TaskClassID
  - conv/schedule_preview.go / service/agent_schedule_preview.go / service/schedule.go：三处透传填充
前端：
5. 排程完毕卡片 + 精排弹窗集成
  - 新增 api/schedule_agent.ts：getSchedulePreview / saveScheduleState / applyBatchIntoSchedule
  - types/dashboard.ts：新增 HybridScheduleEntry / SchedulePreviewData / PlacedItem 类型
  - components/dashboard/AssistantPanel.vue：监听 schedule_completed 事件异步拉取排程渲染卡片，集成 ScheduleResultCard + ScheduleFineTuneModal；confirm 交互从文本消息改为 resume 协议（approve/reject/cancel）
6. ToolTracePrototypeView 原型页新增日程小卡片 + 拖拽编排弹窗演示
7. DashboardView import 区域尺寸微调
