后端： 1. 工具执行结果协议升级为结构化 ToolExecutionResult——execute/tool_runtime、ToolRegistry、stream extra 与 timeline 持久化统一改为透传 observation_text / summary / argument_view / result_view，不再只回写纯文本结果；context_tools、upsert_task_class 与旧 schedule/web 工具通过兼容包装接入新协议 2. 日程写工具注册继续收口——place / move / swap / batch_move / unplace / queue_apply_head_move 从 registry 内联实现下沉为独立 handler，降低注册表内参数解析与业务逻辑混写 3. 工具结果展示基础能力补齐——新增 execution_result / schedule_operation_handlers 公共件，为日程操作结果、参数本地化展示、blocked/failed/done 状态统一建模 前端： 4. AssistantPanel 接入结构化工具卡片渲染——新增 ToolCardRenderer，tool_call / tool_result 支持 argument_view / result_view 展示；schedule_completed 恢复为时间线内的占位卡片块，避免排程卡片脱离原消息顺序 5. 时间线类型与渲染收敛——schedule_agent.ts 补齐 ToolView 协议，AssistantPanel 改为按块渲染 tool / schedule_card / business_card，并移除旧 demo/prototype 路由与页面，收束正式面板代码路径 仓库： 6. AGENTS.md 新增协作约束——禁止擅自回滚、覆盖或删除用户/其他代理产生的工作区改动
