`plan_update` 维护待办清单并在输入框上方展示，未完成项会催办；`request_approval` 下首次 ≥2 项清单会先确认，`auto` 直接建立。`ask_user` 可弹出选项并结束本轮。个人记忆由 `remember_lesson` 写入待审，用户在「设置 → Agent 记忆」自己批准、添加、导出导入，并可用自己的文本模型手动或按日/周/月压缩相近条目。系统提示只带已批准记忆的索引（标题+适用场景），完整做法由 `recall_lessons` 按 topic/关键词取；管理员可按用户查看和删除，不能代批。只读模式不能写记忆。终态旧轮次按其冻结合同保留为不可变历史，新消息使用当前合同创建新轮，不篡改父运行；旧合同下仍活动或待审批的运行不会被新版服务恢复执行。生成由预算和独立审批控制，画布写入使用内容快照哈希；未开放外部 MCP。系统行为策略以版本化资源发布，用户/项目/画布可编辑常驻偏好；偏好正文固定在运行快照并按层只读，不整段塞入 system prompt，也不能提权或跳过审批。节点创建、更新字段、摘要投影和连线限制来自服务端能力 registry；能力卡同时描述用途、适用场景、不适用场景、维护代价和可用动作，由 Agent 结合镜头数量、连续性、逐镜审查和交接需求自主选择，不强制所有任务使用分镜。分镜脚本支持结构化创建、分页读取及按真实行 ID 追加、修改和删除；普通文本和 Markdown 不会被宣称为具备镜头级维护能力的分镜表。图片、视频和音频节点可安全修改标题与下一版提示词草稿，既有媒体、已提交提示词和任务状态不会被草稿编辑覆盖；媒体模型按生成模式和真实参考节点从统一目录筛选。审批和执行记录明确展示目标节点、类型、修改字段、名称变化及连线两端，前端不再依靠内部 ID 猜测；这些预览不替代服务端归属、快照、Capability、锁、预算与调用哈希校验。真实模型计费与浏览器联调仍待验收。 +云端画布 Agent 已分离行为策略、用户目标、参考事实和运行状态。续聊保留已送达插话，不再继承代码预设的创作自由；旧待办只作上下文，可移除取消项，催办不会强制工具调用或无限重复。提示词来源与发布约束见[画布 Agent
