后端：
1. taskclass 执行闭环继续收紧——Plan / Execute 全面切到“最小工具闭环”视角，明确学习目标/总节数/禁排时段/排除星期默认停留 taskclass 域；未给日期范围时禁止擅自补 start_date/end_date，upsert_task_class 重试前先做写前检查并区分“内部表示修正”与“必须追问用户”的关键时间事实
2. QuickTask / TaskQuery 轻量链路继续收敛——新增 model/taskquery_contract.go 统一查询协议，QuickTaskDeps / start.go 改用 model 层参数；删除 query_tasks / quick_note_create 旧工具实现，避免任务查询与随口记再回流 execute 工具链
3. schedule 微调工具继续瘦身——下线 spread_even / min_context_switch 及其复合规划逻辑，清理 analyze_load / analyze_subjects / analyze_context / analyze_tolerance 等历史能力；execute 顺序策略收敛为局部 move / swap，提示词与工具目录仅暴露当前真实可用工具
4. 执行与时间线体验补齐——execute 为流式 speak 补发归一化尾部，避免 deliver 文案黏连；前端时间线新增 interrupt / status 协议识别、工具事件归并与状态过滤，减少 ToolTrace 重复和会话重建误判
前端：
5. AssistantPanel 适配新版 timeline extra 事件——schedule_agent.ts 补齐 interrupt / status kind，工具调用与结果按摘要/参数/工具名合并，恢复历史时不再把协议事件误判成用户消息
