-## 重大功能规划
+## 规划原则
 
-### Agent 框架与协作能力
+规划中的工作流、Subagent、MCP、远程 API 和沙盒能力不得绕过现有 Main Runtime、Ask/Execute、权限、取消、超时和审计边界。
-
-参考 MesaLogo 中已经存在或正在验证的 Action Space、受控工作流、Subagent、MCP 管理、批量实验和运行观测思路，GoodBuddy 计划在现有本地优先架构上逐步增加以下能力。这里列出的项目均为 GoodBuddy 自身规划，不表示 MesaLogo 的原型或路线图已在 GoodBuddy 中提供。
-
-- [ ] **项目 Agent Space 与策略包**：不新增与 Project 重复的一级概念，而是在现有 Project 中统一角色、知识集合、Skills/MCP、默认模型、变量、工作模式、审批策略、预算和超时，并支持模板化复用。
-- [ ] **统一 Run Graph**：先统一父子任务、节点、模型调用、知识命中、工具审批、用量、成果和取消事件，作为工作流、可执行 Subagent、批量实验和回放的共同基础。
-- [ ] **MCP Server Control Plane**：由 Main 进程统一管理 `stdio`、HTTP 和 SSE Server，执行连接验证、健康检查、重连、Schema 缓存、环境变量白名单、资源配额、项目或任务隔离以及逐次审批和审计。
-- [ ] **可视化受控工作流**：首版只支持开始、Agent/Subagent、知识、声明式条件、审批、成果和结束节点；流程需要版本化、校验、取消和恢复。任意网络请求或执行节点不得绕过现有 Runtime 与审批边界。
-- [ ] **可执行 Subagent**：保留现有专家默认只读语义，只在显式 Execute 委派中允许受控工具，限制深度、并行数、Token、时间、成果范围和父子权限继承。
-- [ ] **批量运行与对比实验室**：对模型、Prompt、角色和工作流版本进行参数扫描与 A/B 对比，展示质量评分、耗时、Token、费用、失败率和成果差异。
-- [ ] **时态记忆与事实冲突检测**：在现有知识图谱和证据链上增加事实有效期、当前状态、过期与矛盾检测、核验流程及来源回溯。
-- [ ] **Headless Runtime API**：作为可选、本机默认仅监听 loopback 的服务，提供任务提交、流式事件、状态和成果下载；访问令牌必须具有 scope、有效期、速率限制、项目限制和撤销能力。
-- [ ] **GoodBuddy Team Hub**：作为独立可选服务提供组织、成员、RBAC、项目共享、远程 Agent 注册、策略下发和租户级审计，不把 Electron Renderer 或云端服务改造成用户凭据持有者。
-
-安全边界保持不变：Ask/Plan 必须在 Runtime 边界只读；Execute、MCP、网络和 Subagent 工具均受 Main 进程能力边界、权限策略、取消和审计约束。普通交互按对应策略审批；受信发送者发起的远程 Execute 不逐次弹窗确认，但不得绕过项目目录、Runtime、沙箱、能力开关或直连模型工具安全策略。不得照搬进程内脚本执行、任意 URL 请求、仅以 `created_by` 模拟多租户或共享无隔离 MCP 会话等做法。

-### 知识工作空间与魔法笔记
-
-- [x] **魔法笔记 / Magic Notes 基础工作台**：已提供本地优先的笔记与待办页签、范围管理、编辑、筛选、删除和受控 AI 评论。
-- [ ] **可追溯摘录扩展**（规划中）：支持将用户选中的对话片段、知识条目、文档摘录和网页摘录收集为可编辑笔记，并持续保留来源、位置和引用关系。
-- [ ] **扩展受控 AI 笔记操作**（规划中）：在现有 AI 评论之外提供总结、改写、续写、整理和关联知识等显式操作；操作结果先进入笔记或待确认变更，不静默回写或修改来源知识。
-
-### 多云远程沙盒 Agent
-
-GoodBuddy 将支持把专用云主机作为模型可自主使用的远程沙盒。首批计划接入：
-
-- 阿里云 ECS
-- 腾讯云 CVM
-- AWS EC2
-- 其他可通过 SSH 管理的 Linux 主机
-
-计划包含以下能力：
-
-- [ ] **云主机控制面**：通过云厂商官方 API 发现、创建、启动、停止和删除实例，创建前展示地域、规格、镜像、网络和费用相关配置。
-- [ ] **SSH + GoodBuddy Agent**：校验 SSH 主机指纹后，以专用非 root 账户安装、升级和配对 Agent，不要求模型接触 SSH 私钥。
-- [ ] **沙盒内自主执行**：用户可将明确指定的专用实例设为自主沙盒。模型在该沙盒的工作目录内连续执行命令、修改文件和运行任务，不逐条请求审批。
-- [ ] **控制面与执行面隔离**：云 API 密钥、临时凭据和 SSH 私钥只保存在 Main 进程的系统加密存储中，不下发给 Renderer、模型或远程任务。模型的自主权限不包含云账户管理权限。
-- [ ] **高风险操作保护**：删除实例、修改安全组或网络、扩缩容和其他可能产生额外费用或数据损失的控制面操作仍需单独确认。
-- [ ] **可观测与可恢复**：实时回传心跳、日志、进度、退出状态和有界成果文件，支持取消、超时、断线重连、失败诊断和完整活动审计。
-- [ ] **跨云一致体验**：使用统一的实例状态、Agent 能力和任务协议；阿里云、腾讯云、AWS 的差异由独立 Provider Adapter 隔离。

+
+## Highlights
+
+- **Controlled execution**: `Ask` stays read-only; `Execute` runs only enabled tools within defined boundaries and records their activity.
+- **Local-first data**: Conversations, tasks, artifacts, memory, knowledge bases, and graphs are stored in local SQLite. API keys are encrypted by the operating system.
+- **Multiple runtimes**: Connect directly to models or use OpenCode and Continue, with cancellation, timeouts, output limits, and process cleanup.
+- **Open integrations**: Supports OpenAI Responses, OpenAI-compatible Chat Completions, Anthropic Messages, OpenAI Images, Embeddings, Skills, and MCP.
+- **Knowledge workspace**: Import files, folders, and web pages, then search them with full-text, phrase, vector, and graph retrieval.
+- **Work management**: Organize projects, conversations, tasks, activity, artifacts, memory, Magic Notes, and Smart Heartbeat.
+- **Remote channels**: Connect WeChat ClawBot, WeCom, and DingTalk with separate remote sessions for each sender.
+- **Desktop context**: Add selected files, screenshots, application windows, clipboard content, and voice.
+- **Offline speech**: Use local SenseVoice, Paraformer, and Whisper models.
+- **Rich responses**: Render Markdown, LaTeX, and controlled Mermaid diagrams.

-### 多 Runtime 与模型连接
+## 安装
 
-| 能力 | 适用场景 | 控制方式 |
+从 [GitHub Releases](https://github.com/mesalogo/goodbuddy/releases) 下载：
+
+| 系统 | 架构 | 格式 |
 | --- | --- | --- |
-| 直连模型 | 问答、知识总结、受控工具执行、图像生成 | Ask 只读；Execute 自动授权已启用的工作区、浏览器与 MCP 工具，可设置为全部禁止 |
+| Windows | `x64`、`arm64` | NSIS、便携 ZIP |
-| OpenCode | 完整编码与工作区任务 | Execute 不弹 GoodBuddy 审批，保留 Runtime 自身权限、取消和活动记录 |
+| macOS | `x64`、`arm64` | DMG、ZIP |
-| Continue | Agent 编码与工作区任务 | Execute 不弹 GoodBuddy 审批，使用独立宿主、取消和活动记录 |
+| Linux | `x64`、`arm64` | AppImage、DEB |
 
-消息通道选择 OpenCode 或 Continue 时只选择 Runtime 类型，具体模型来源、自有配置、可执行文件和服务地址统一复用“Agent Runtime”设置，并在每次远程请求开始时解析当前全局配置。
+当前尚未配置代码签名和 macOS notarization，系统可能显示安全提示。

-## 隐私说明
+## 隐私与安全
 
-模型请求只会发送到用户选择的模型连接。本地数据保存在当前系统的应用数据目录中；远程委派仅在用户显式配置端点和令牌后启用。为兼容受控私有网络，GoodBuddy 进程管理的连接允许 HTTP，并接受无效、自签名或过期的 HTTPS 证书；交由外部浏览器打开的 URL 仍遵循浏览器自身的证书策略。微信凭据和媒体端点不受该策略放宽，始终只允许经过校验的腾讯微信 HTTPS 主机与重定向。
+- 模型请求只发送到用户选择的服务。
+- 本地数据默认保存在系统应用数据目录。
+- Renderer 不接触原始 Electron API 或模型凭据。
+- 远程委派仅在用户配置端点和令牌后启用。
+- 内网兼容模式允许应用内 HTTP 和非标准 HTTPS 证书；微信凭据和媒体端点仍执行严格校验。

+# GoodBuddy 自维护 DeepSeek Harness Runtime 设计
+
+## 1. 文档信息
+
+| 项目 | 内容 |
+| --- | --- |
+| 文档状态 | 实现与发布验收基线 |
+| 设计目标 | 将 DeepSeek Harness 作为 GoodBuddy 的第三个 Agent Runtime |
+| Runtime 标识 | `deepseek-harness` |
+| 首版依赖基线 | 实际使用的 `@deepseek-ai/dsh-*` 底层库，精确锁定 `0.1.0-rc.6` |
+| 上游状态 | Developer Preview，允许出现破坏性变更 |
+| 上游许可证 | MIT |
+| GoodBuddy 目标平台 | Windows、macOS、Linux，x64 与 arm64 |
+| 本文性质 | 设计与发布验收约定 |
+
+本文定义 DeepSeek Harness 在 GoodBuddy 中的架构边界、协议、安全策略、界面、打包和验收要求。实现必须继续遵守 GoodBuddy 已有的 Main 进程安全边界、Ask/Execute 语义、授权、取消、超时、有界输出和资源回收约定。
+
+## 2. 摘要
+
+DeepSeek Harness 的底层库使用 Cordis 组合服务。GoodBuddy 不采用官方产品 profile、插件安装或市场机制，也不让用户配置覆盖安全服务，而是增加一个实验性的第三 Runtime，并完全自行维护 Host、控制协议、生命周期和兼容层。上游 DSH 包只是精确锁定并逐次审查的实现依赖，不构成 GoodBuddy 对 DSH 插件 ABI、插件目录或产品路线的承诺。
+
+GoodBuddy 并不迫切于把该能力做成 DSH 插件或进入插件市场。当前优先级是向用户提供稳定、可靠、可审计且可完整回收的 Runtime；只有未来真实用户需求和成熟度证明插件化确有价值时，才重新评估该形态。
+
+整体分成两个互相约束的部分：
+
+1. **GoodBuddy Main Control Plane**
+   - 运行在 Electron Main 进程。
+   - 持有加密设置、模型连接选择、Ask 拒绝与 Execute 自动授权策略、Runtime 生命周期和审计归属。
+   - 通过 Electron `utilityProcess` 启动受控 Harness 子进程。
+   - 对环境、输入、输出、超时、取消和进程树执行强制限制。
+
+2. **GoodBuddy Harness Control Plane**
+   - 运行在 Harness 子进程内，是 Host 私有的内部控制组件，不导出 Cordis 插件入口。
+   - 使用 ACP 兼容的 JSON-RPC stdio 作为基础控制面。
+   - 增加 GoodBuddy 所需的能力握手、每轮权限准备、会话释放、工具事件、推理、用量和安全凭据请求扩展。
+   - 与 GoodBuddy Host 一起维护、构建和发布，不设计为独立 npm 包、`dsh.bundle` 或市场插件。
+
+DeepSeek Harness 不替换 OpenCode、Continue 或直连模型 Runtime。用户可以按全局、项目、会话或消息通道继续选择现有 Runtime。
+
+## 3. 背景与上游能力
+
+### 3.1 已确认的官方能力
+
+- `@deepseek-ai/dsh` 是官方 profile 启动器。
+- Harness 插件是导出 `apply(ctx, config)` 的 Cordis 模块。
+- npm 包可通过 `dsh.bundle` 声明配置补丁，再通过 `dsh plugin --profile <name> add <package>` 安装。
+- ACP 支持：
+  - 初始化。
+  - 创建多个会话。
+  - 发送 Prompt。
+  - 按会话取消。
+  - 一次性权限选择。
+  - 已提交的助手文本。
+- 官方本地沙箱支持：
+  - Linux：Bubblewrap，或 Landlock 降级。
+  - macOS：Seatbelt。
+  - Windows：ACL 受限令牌，官方明确标记为部分强制执行。
+
+### 3.2 官方通道的缺口
+
+官方 ACP 插件有意只输出已提交文本，不输出推理、工具进度、计划、标题和用量。它也没有标准的会话关闭方法。SDK JSON-RPC 的展示事件更完整，但缺少 GoodBuddy 需要的单轮取消和权限回传。
+
+因此，首版不单独选用其中一个官方通道作为完整实现。GoodBuddy Harness Control Plane 以 ACP 语义为基础，补充有命名空间的扩展方法和事件。
+
+### 3.3 自维护边界
+
+GoodBuddy 不急于把该 Runtime 包装成标准 DSH 插件，也不以进入官方或第三方插件市场为近期目标。所有入口都随 GoodBuddy 发布，只有 GoodBuddy Main 可以启动并使用内部 Host。是否采用上游新版本或未来重新评估插件形态，只由真实用户价值、安全审查和六平台稳定性决定，不跟随市场机制或上游发布节奏。
+
+## 4. 目标与非目标
+
+### 4.1 首版目标
+
+- 增加 `deepseek-harness` Runtime，并在设置、聊天和消息通道中可选择。
+- 使用 GoodBuddy 管理的模型连接，不在 Renderer 或持久化 Harness 配置中写入 API Key。
+- Ask 模式在 Runtime 边界强制只读，并禁止任何权限升级。
+- Execute 模式下的工具权限请求由 Main 自动给予单次授权，不弹出交互审批；默认文件模式仍为 `workspace-write`，越界仅允许在真实沙箱拒绝后对完全相同操作单次重试。
+- 支持多会话、同会话串行、跨会话并行。
+- 支持按请求取消、超时、会话释放和应用退出时完整回收。
+- 输出文本、推理、工具参数、工具结果、stderr 和协议队列全部有界。
+- 使用真实 OpenAI 兼容 Chat Completions 模型验证调用，而不在日志、测试产物或提交中暴露凭据。
+- 保留 Windows、macOS、Linux 的 x64 和 arm64 发布能力。
+
+### 4.2 首版非目标
+
+- 不替换 OpenCode、Continue 或直连模型 Runtime。
+- 不开放用户 Cordis profile、cordis.patch.yml 或 $DSH_HOME 全局补丁覆盖。
+- 不提供外部 Host、自定义 Harness Control Plane、DSH 插件安装或市场入口。
+- 不加载 Harness Web UI、HMR、遥测、自动更新或目录选择器。
+- 不支持 `danger-full-access` 作为会话默认值或持久设置。
+- 不向 Utility 暴露 MCP 凭据或建立直连 MCP Client。只有用户明确分配给 Harness 的 MCP 工具可以通过 Main 代理调用。
+- 不在首版向 Harness 暴露 GoodBuddy 浏览器控制、知识库或 Magic Notes。
+- 不在首版支持图像输入、会话恢复、Harness Subagent、后台 Job、Hook、Web Search 或 Workflow。
+- 不发布独立 npm 包，也不创建上游 PR。
+
+## 5. 核心设计决策
+
+### 5.1 第三个独立 Runtime
+
+`deepseek-harness` 是明确的 Runtime 类型，不伪装成 `model`、`opencode` 或 `continue`。共享契约、设置迁移、Runtime 选择、检测、聊天标签、消息通道和模型用量都使用同一个稳定标识。
+
+### 5.2 受控组合，不启动用户 profile
+
+GoodBuddy 使用自己固定的 Harness Host 入口和只读组合模板，不调用 `dsh web`，也不启动用户已有 profile。运行时禁止以下来源参与组合：
+
+- 当前工作目录的 `.env`。
+- 用户 Harness Home 的 `.env`。
+- `$DSH_HOME/cordis.patch.yml`。
+- 用户 profile 的 `cordis.patch.yml`。
+- 任意 `--patch`。
+- HMR 和动态插件安装。
+
+模型名称、服务地址、工作区和非秘密策略通过严格校验的 Main 配置传给 Host。API Key 只通过受控凭据通道按需提供，不写入 YAML、命令行、Renderer 或日志。
+
+### 5.3 双层内部控制面
+
+Harness 子进程内控制面不能取代 Main 控制面，Main 控制面也不能代替进程内的 Session/Tool 适配层：
+
+- Harness Control Plane 最接近 Session、Agent、Tool、Usage 和权限 seam，适合做内部协议转换。
+- Main 控制面是可信安全边界，适合持有模式授权策略、加密设置、进程控制和 IPC。
+
+任何一侧缺失能力握手时，Runtime 必须报告不可用，不能降级为不受控执行。
+
+### 5.4 GoodBuddy 继续拥有持久会话
+
+首版不启用 Harness JSONL 会话持久化和 SQLite 会话索引。原因如下：
+
+- GoodBuddy 已经持久化对话、消息、活动、工具事件和用量。
+- 再写一份 Harness 日志会扩大敏感数据副本和清理范围。
+- GoodBuddy 在 Runtime 重启后可以用现有的有界历史创建新 Harness Session。
+
+Harness Session 只在当前 Runtime 进程生命周期内存在。释放 GoodBuddy 会话时必须同步释放对应 Harness Agent。
+
+## 6. 总体架构
+

+Electron Main
+  ├─ RuntimeSettingsStore

+
+### 6.1 信任边界
+
+| 区域 | 信任级别 | 允许持有的内容 |
+| --- | --- | --- |
+| Renderer | 不可信展示层 | 脱敏设置、状态、用户可见事件 |
+| Preload | 窄桥 | 明确方法和共享 schema |
+| Electron Main | 可信控制面 | 加密设置、模式授权策略、Runtime 生命周期 |
+| Harness utilityProcess | 不可信执行面 | 当前请求、临时凭据、受控工具和工作区权限 |
+| Harness 工具子进程 | 最低信任 | 单次命令所需的最小环境和沙箱能力 |
+
+Harness 子进程崩溃、输出异常、拒绝协议、加载错误或沙箱不可用时，Main 必须失败关闭。
+
+## 7. GoodBuddy Harness Control Plane
+
+### 7.1 内部组件职责
+
+控制面负责：
+
+- 启动 ACP 兼容的 JSON-RPC stdio 服务。
+- 创建、查找和释放 Harness Agent。
+- 在 Prompt 前应用 GoodBuddy 指定的 Ask/Execute 权限。
+- 将 DSH Session 事件转换为有界的 GoodBuddy 事件。
+- 将权限请求转发到 Main，并只接受一次性结果。
+- 将 LLM 用量转换为稳定的模型用量事件。
+- 在 dispose 时先取消 Agent，再等待子 Agent 和工具清理。
+- 保证 stdout 只包含协议帧，诊断只写 stderr。
+
+控制面不负责：
+
+- 保存 GoodBuddy 设置。
+- 持久保存 API Key。
+- 决定 Main 的模式授权结果。
+- 直接访问 Renderer 或 Electron API。
+- 接受用户提供的插件、Host 或 profile 覆盖。
+- 自行上传遥测。
+
+### 7.2 非插件约束
+
+控制面不导出 `apply(ctx, config)`，不提供默认 stdin/stdout 入口，不包含 `dsh.bundle`、`cordis.patch.yml` 或可安装 manifest，也不接受 Host 之外创建的 transport。它可以保留清晰的内部模块边界以便测试和维护，但该边界不是公开扩展点。
+
+若未来确有来自 GoodBuddy 真实用户、经过研究验证的扩展需求，应先重新完成产品需求、威胁模型和兼容策略评审；不得因为上游已经提供插件或市场机制而默认开放。
+
+## 8. 协议设计
+
+### 8.1 传输
+
+- stdin/stdout 使用换行分隔 JSON-RPC。
+- stdout 不得出现日志、Banner、进度条或调试输出。
+- stderr 只允许有界诊断，不得包含 Prompt、工具完整输出或凭据。
+- 每一帧、每一字段和每个请求累计输出都必须在解析前或接收时限流。
+
+### 8.2 标准 ACP 方法
+
+首版保留 ACP 的初始化、`session/new`、`session/prompt` 和 `session/cancel` 语义。标准 ACP 客户端可以使用只读默认行为，但只有完成 GoodBuddy 能力握手的客户端才能启用 Execute。
+
+### 8.3 GoodBuddy 扩展
+
+扩展统一使用 `goodbuddy/` 命名空间：
+
+| 方法或事件 | 方向 | 用途 |
+| --- | --- | --- |
+| `goodbuddy/handshake` | Main → Control Plane | 交换控制协议、Harness、ACP 版本和能力 |
+| `goodbuddy/session/prepare` | Main → Control Plane | 在下一次 Prompt 前设置工作模式和请求标识 |
+| `goodbuddy/session/release` | Main → Control Plane | 取消并释放指定 Session |
+| `goodbuddy/session/event` | Control Plane → Main | 文本、推理、工具、状态和用量事件 |
+| `goodbuddy/credential/resolve` | Control Plane → Main | 按已登记引用请求当前 Runtime 的临时凭据 |
+| `goodbuddy/tools/list` | Control Plane → Main | 取得用户分配给 Harness 的有界 MCP 工具 schema |
+| `goodbuddy/tools/call` | Control Plane → Main | 通过当前 Execute 请求、schema 校验和自动单次授权调用 MCP |
+| `goodbuddy/shutdown` | Main → Control Plane | 停止接收新请求并有序清理 |
+
+扩展版本独立于 ACP 版本。握手响应至少包含：
+
+```ts
+type GoodBuddyHarnessCapabilities = {
+  controlProtocolVersion: 1
+  harnessVersion: string
+  acpProtocolVersion: number
+  supports: {
+    cancellation: true
+    sessionRelease: true
+    oneShotApproval: true
+    reasoningEvents: boolean
+    toolEvents: boolean
+    usageEvents: boolean
+  }
+  sandbox: {
+    provider: string
+    enforcement: 'full' | 'partial'
+  }
+}
+```
+
+版本不兼容、必需能力缺失或 `sandbox.enforcement` 不满足设置要求时，Main 不得开始模型请求。
+
+### 8.4 每轮权限准备
+
+GoodBuddy 的工作模式属于每个请求，不属于 Runtime 进程全局状态。同一对话可以在 Ask 和 Execute 之间切换。因此：
+
+1. `session/new` 后默认是 `read-only + never`。
+2. 每个 Prompt 前，Main 发送一次 `goodbuddy/session/prepare`。
+3. Harness Control Plane 将准备状态绑定到 `sessionId + requestId`。
+4. `session/prompt` 只能消费匹配且尚未使用的准备状态。
+5. 缺少准备状态、重复使用、请求标识不匹配时，Control Plane 使用只读且禁止授权的安全默认值，或直接拒绝请求。
+6. 同一 Session 只允许一个 Prompt 在途。
+
+### 8.5 事件模型
+
+Harness Control Plane 只发送 GoodBuddy 能稳定解释的字段：
+
+- `status`：简短运行状态。
+- `text`：已提交的助手文本分片。
+- `reasoning`：可选的有界推理摘要分片。
+- `tool`：工具 ID、名称、状态和有界输入/输出摘要。
+- `model-usage`：模型、提供方、输入、输出和缓存 Token。
+- `done`：停止原因和 Session ID。
+
+禁止发送原始 Cordis Context、完整环境、内部对象、堆栈中的凭据或无界 Session 日志。
+
+## 9. Runtime 生命周期
+
+### 9.1 进程模型
+
+- 每个活动的 DeepSeek Harness Runtime 实例拥有一个 `utilityProcess`。
+- 一个进程可以承载多个 Harness Session。
+- 同一 GoodBuddy 对话的 Prompt 串行执行。
+- 不同对话可以并行，但受全局并发上限控制。
+- Runtime 设置变化时创建新实例，旧实例等待在途请求结束或在宽限期后被取消。
+
+### 9.2 会话映射
+
+Main 保存内存映射：
+
+```text
+GoodBuddy conversationId -> Harness sessionId + process generation
+```
+
+- 首次请求创建 Session。
+- 已有 Session 只发送当前 Prompt。
+- 进程重启或映射失效时，创建新 Session，并只在这一次加入 GoodBuddy 提供的有界历史。
+- 历史以明确的“不可信会话数据”结构传入，不能拼接成系统指令。
+- 用户分配的 Skill 只通过 Main 校验的包路径进入 Host，并在 Agent scope 注册；不得把 Skill 内容伪装成用户 Prompt。
+
+### 9.3 取消与超时
+
+- 用户取消时立即发送 `session/cancel`。
+- 取消等待有界，超时后关闭连接并终止整个 Harness 进程。
+- 初始化、握手、Session 创建、Prompt、权限回传和关闭分别使用独立超时。
+- Prompt 超时与用户取消使用不同错误类型，不能被宽泛 catch 抹平。
+- 取消后仍可接收并丢弃该请求的最终协议结算帧，但不得写入下一请求。
+
+### 9.4 释放与退出
+
+- 删除或释放对话时调用 `goodbuddy/session/release`。
+- Runtime dispose 时先拒绝新请求，再取消所有 Session。
+- Harness Control Plane 完成 Agent、工具和会话清理，Host 完成 Cordis Fiber 与子进程的反向清理。
+- Main 在宽限期内等待正常退出。
+- 超时后终止 utilityProcess，并在平台允许时清理完整进程树。
+- 应用退出不得因 Harness 清理无限阻塞。
+
+## 10. 权限与沙箱
+
+### 10.1 模式映射
+
+| GoodBuddy 模式 | DSH 文件模式 | DSH 权限策略 | 行为 |
+| --- | --- | --- | --- |
+| Ask | `read-only` | `never` | 允许受控读取，不允许写入，不允许升级 |
+| Execute | `workspace-write` | `ask` | 允许工作区与受控临时目录写入；权限请求由 Main 自动单次授权，不弹出交互审批 |
+
+`danger-full-access` 只能作为某个已被沙箱拒绝的完全相同操作的一次性、更宽重试。Main 仅对该次重试自动返回 `allow-once`；它不能保存为默认值、复用于后续操作，或通过“始终允许”返回。
+
+### 10.2 Ask 模式
+
+- Main 即使收到权限请求也固定拒绝。
+- Harness Control Plane 禁止 `sandbox_permissions` 升级。
+- 文件写入和 Shell 写入都由 DSH 共享 Sandbox Policy 强制拒绝。
+- 只读不等于无限输出，读取仍受路径、字节和工具结果上限控制。
+- 首版不向 Ask 暴露 GoodBuddy 的可变数据工具。
+
+### 10.3 Execute 模式
+
+- 工作区根来自 Session 创建时的规范化绝对路径。
+- 工具不能自行更换工作区根。
+- 工作区内操作按 DSH `workspace-write` 执行。
+- 只有真实沙箱拒绝后的同一操作，才可请求一次升级。
+- Main 不调用 `ToolApprovalBroker`，而是对当前 Execute 请求自动返回 `allow-once`；界面不进入等待审批状态，也不弹出审批对话框。
+- 所有工具调用仍作为活动事件记录；Ask 和 delegation 路径继续固定拒绝。
+- Harness Control Plane 不接受 `allow_always`，也不把未知结果解释为允许。
+
+### 10.4 沙箱可用性
+
+- `strict`：要求完整强制执行。仅有 `partial` 或无 Runner 时 Runtime 不可用。
+- `auto`：允许官方报告的 `full` 或 `partial`，但必须在状态卡显示实际强制程度。
+- `off`：不允许 Harness 退化到无限制工具执行。首版将 Execute 标记为不可用，Ask 仍只能在可强制只读时运行。
+
+Windows ACL 和旧 Linux Landlock 可能只报告 `partial`。界面和诊断必须如实显示，不能写成“完全隔离”。
+
+### 10.5 环境与凭据
+
+- 使用环境变量白名单构造 utilityProcess 环境。
+- 不继承 `NODE_OPTIONS`、调试端口、任意 npm 配置、用户 `DSH_*` 覆盖或白名单之外的凭据。
+- `DSH_TELEMETRY_DISABLED=1` 必须固定设置。
+- Harness Home 指向 GoodBuddy 管理的隔离目录。
+- 不调用官方 `loadEnv` 或 `loadLayeredEnv`。
+- API Key 由 Main 从加密设置中解析。
+- Harness Control Plane 只能用已握手登记的引用通过 `goodbuddy/credential/resolve` 请求当前 Runtime 的凭据。
+- 凭据只在模型请求所需的子进程内存中短暂存在，不写磁盘、不进入工具环境、不打印。
+
+## 11. 受控 Harness 组合
+
+首版只加载完成文本对话、受控代码操作和用户明确分配能力所需的固定服务：
+
+- Agent、Session、LLM 和 Tool Registry 基础服务。
+- GoodBuddy Harness Control Plane。
+- OpenAI 兼容 Chat Completions LLM 适配器。
+- Sandbox Policy 与平台 Sandbox Provider。
+- 平台对应的受沙箱 Shell。
+- 受沙箱 Filesystem。
+- 一次性权限请求服务。
+- Token Meter 和必要的上下文压缩。
+- 有界的读取、写入、编辑和 Shell 工具。
+- Agent scope 的 Skill Registry 与 `skill` 工具。Skill 目录由 Main 选择并在 Launcher 和 Host 两次规范化、校验。
+- Main 代理的 MCP schema 工具。Utility 不持有 MCP URL 凭据或 Transport。
+
+首版明确不加载：
+
+- Web UI、HMR、Host API 和目录选择器。
+- Harness 遥测。
+- Settings File 和 Local Credentials。
+- 用户 profile 与全局补丁。
+- Web Search、Fetch、Utility 直连 MCP、Hooks。
+- Subagent、Workflow、Ralph、后台 Job。
+- JSONL Session Persistence 和 SQLite Session Query。
+- 自动技能发现和市场技能加载。
+
+如果某个首版工具依赖被排除服务，启动审计必须失败，而不是自动加载更大的默认 bundle。
+
+## 12. 模型配置
+
+### 12.1 配置来源
+
+DeepSeek Harness 首版只使用符合下列边界的 GoodBuddy 模型连接：
+
+- 协议必须是 `openai-chat-completions`。
+- 认证必须是 API Key。
+- 公网服务地址必须使用 HTTPS；`localhost`、`127.0.0.1` 和 `::1` 回环地址可以使用 HTTP。
+- 服务地址可以使用自定义主机、端口和部署路径，但不得包含用户名、密码、查询参数或片段。
+- 模型名称不限制为 DeepSeek 品牌，由所选 OpenAI 兼容服务决定。
+- 模型名称和服务地址由 Main 传入受控 Host。
+- API Key 继续保存在 GoodBuddy 加密设置中。
+- 启动环境提供的部署连接只由 Main 自动解析，不在 Renderer 中显示为可选来源。
+
+不允许选择 Harness 自有的用户配置文件或自定义 Host。Runtime 始终使用随当前 GoodBuddy 版本发布的内置 Host，并通过完整内部能力握手。
+
+### 12.2 设置变化
+
+模型、凭据、沙箱、Skill 或 MCP 分配变化时，GoodBuddy 创建新 Runtime 实例。Harness Host 路径始终由当前 GoodBuddy 构建提供，不能由设置或环境变量替换。旧实例按现有 Runtime Controller 语义退役，不在一个活动进程内热替换安全配置。
+
+### 12.3 输入限制
+
+- 首版只支持文本。
+- 图片输入应在发起网络调用前返回明确错误。
+- GoodBuddy 历史、Prompt、系统指令分别保持不同信任层。
+- 任何用户文本都不能进入 Cordis 配置表达式或模块名。
+
+## 13. 输出和资源边界
+
+建议首版默认限制：
+
+| 项目 | 默认上限 |
+| --- | --- |
+| 单个 JSON-RPC 帧 | 1 MiB |
+| 单个文本或推理事件 | 64 KiB |
+| 单次请求累计协议输出 | 4 MiB |
+| 工具输入摘要 | 4,000 字符 |
+| 工具输出摘要 | 4,000 字符 |
+| 待处理事件数 | 1,000 |
+| stderr 累计 | 64 KiB |
+| 初始化 | 10 秒 |
+| 单次 Prompt | 10 分钟 |
+| 有序关闭宽限期 | 2 秒 |
+
+超过限制时应取消当前请求。协议帧、队列或 stderr 持续异常时，应终止 Runtime 进程，避免继续信任已失控的通道。
+
+## 14. Runtime 检测与状态
+
+### 14.1 检测
+
+检测只验证：
+
+- 内置 Host 路径是规范化文件。
+- 版本可读取且在支持范围内。
+- 内部控制面能力握手成功。
+- 必需 Sandbox Provider 可用并报告强制程度。
+
+检测不得调用付费模型，也不得读取或输出 API Key。真实模型测试是单独的显式操作。
+
+### 14.2 设置界面
+
+Agent Runtime 使用共享 `SegmentedControl` 展示 OpenCode、Continue 和 DeepSeek Harness。DeepSeek Harness 必须标记为“开发者预览”，并说明上游 RC 可能发生破坏性变更。
+
+Runtime 的概览、模型配置和检测信息放在同一张详情卡中。当前单独显示的一行“已就绪”应移入卡片，与路径、版本号归为同一组：
+
+```text
+Runtime：       GoodBuddy 内置 DeepSeek Harness
+模型配置：      跟随 GoodBuddy · 企业网关（qwen-plus）
+状态：          已就绪
+路径：          <受控 Host 路径>
+版本：          0.1.0-rc.6
+安全强制：      完整 / 部分
+
+Host 始终由当前 GoodBuddy 版本提供，不存在自定义 Host 入口。
+```
+
+界面要求：
+
+- 不再在卡片外重复一行检测结果。
+- 使用语义化键值结构，路径允许换行，不截断关键信息。
+- 状态不能只依靠绿色表达，必须同时有文字。
+- 检测中、不可用和部分强制分别显示明确文案。
+- 高级设置默认收起。
+
+聊天顶栏只显示简短 Runtime 状态，不显示文件路径和版本。完整诊断只在设置页展示。
+
+## 15. IPC 与共享契约
+
+共享 schema 需要覆盖：
+
+- `deepseek-harness` provider 和 Runtime ID。
+- Runtime 选择中的 `deepseekHarness` 分支。
+- 检测结果中的路径、版本、详情和沙箱强制程度。
+- GoodBuddy 模型连接选择。
+- DeepSeek Harness 模型用量归属。
+- Skill 与 MCP 对 `deepseek-harness` 的显式分配。
+
+Renderer 只接收脱敏状态。任何凭据、完整环境、启动参数或内部 Cordis 配置都不能进入共享契约。
+
+已有设置迁移必须：
+
+- 对没有新字段的用户使用安全默认值。
+- 保留 OpenCode、Continue 和模型连接选择。
+- 修复失效的 DeepSeek Harness 模型引用时给出可报告的迁移警告。
+- 不把旧 Runtime 自动迁移为 DeepSeek Harness。
+
+## 16. 打包与供应链
+
+### 16.1 版本策略
+
+- 官方 RC 包全部精确锁定，不使用 `^` 或 `~`。
+- 同一 Harness 核心包族必须保持同一 RC 版本。
+- 升级前检查 release diff、协议 diff、沙箱 diff和依赖闭包。
+- 内部握手同时检查锁定的 Harness 基线和 GoodBuddy 控制协议版本。
+
+### 16.2 原生依赖
+
+受控组合可能需要：
+
+- `node-pty`，用于受管理的工具子进程。
+- `koffi`，用于 Windows ACL 或相关本地能力。
+- `@deepseek-ai/node-addon-landlock-run` 的平台包。
+
+不得广泛批准所有安装脚本。只允许生产组合实际需要、来源已审查、版本已锁定的脚本。六个平台的构建必须验证：
+
+- 对应架构的原生文件存在。
+- Electron Utility Process 可加载原生模块。
+- Runner 或 spawn helper 的权限正确。
+- 包中没有混入其他平台不需要的可执行内容，除非上游包无法拆分且已记录。
+
+### 16.3 生产闭包
+
+发布包只包含受控 Host 需要的插件和许可证。应尽量避免把 Harness Web profile、HMR 和其他未加载产品面带入生产闭包。若 npm 依赖结构无法拆分，必须：
+
+- 确认这些模块不会被加载。
+- 评估它们带来的 audit 和体积风险。
+- 在后续上游版本允许时改为最小包族。
+- 确认 `tests/fixtures` 以及 Web3D 测试 Skill/MCP 不进入正式发布资源。
+
+### 16.4 漏洞门禁
+
+当前安装后的 `npm audit` 报告不能直接用 `npm audit fix --force` 处理。每项漏洞需要区分：
+
+- GoodBuddy 既有依赖。
+- Harness 新增生产依赖。
+- 仅开发或打包依赖。
+- 未加载但被带入的 Web 依赖。
+
+进入 Harness 执行路径且有可利用条件的高危问题必须在发布前修复、替换或移出生产闭包。
+
+### 16.5 发布验证
+
+`build/build-release.cjs` 需要验证：
+
+- Harness Host 和受控配置存在。
+- GoodBuddy Host、内部控制协议与 Harness 依赖版本清单存在。
+- 平台原生 Sandbox/PTY 依赖架构正确。
+- Harness、ACP SDK 和其他新增第三方许可证已打包。
+- `app.asar` 外需要执行或动态加载的资源位于预期目录。
+- Web3D Skill/MCP 等测试 fixture 不在 `app.asar` 或 `extraResources` 中。
+
+## 17. 测试策略
+
+### 17.1 单元测试
+
+- Runtime 选择、设置迁移和失效引用修复。
+- 二进制检测、版本解析和路径规范化。
+- ACP 握手、事件转换和请求关联。
+- 每个会话单请求、跨会话并行。
+- Ask 固定拒绝升级。
+- Execute 权限请求由 Main 自动返回单次授权，Ask 与 delegation 固定拒绝。
+- 未分配 Skill/MCP 不可见；分配后的 Skill catalog 可调用 `skill` 加载。
+- Ask 不注册 MCP 工具；Execute 每轮刷新有界 schema，并在调用前再次校验活动请求、模式、参数和自动单次授权。
+- MCP URL、启动命令和凭据不进入 Utility 启动配置或协议结果。
+- 未知授权结果失败关闭。
+- 超时、取消、迟到帧和进程意外退出。
+- 协议帧、事件队列、工具摘要和 stderr 上限。
+- release 和 dispose 的幂等性。
+- 状态卡中的状态、路径、版本和强制程度。
+
+### 17.2 本地集成测试
+
+使用无网络的假控制面/模型验证：
+
+- utilityProcess 管道。
+- 多 Session。
+- Session 释放。
+- Runtime 替换。
+- 进程树回收。
+- 受控配置不会读取工作区 `.env` 和用户 DSH 配置。
+
+### 17.3 真实模型测试
+
+真实测试已经获得用户授权，但必须由显式环境门禁启用。Web3D Skill 和 MCP 仅作为 `tests/fixtures` 下的测试资产使用，不属于内置发布能力。至少验证：
+
+1. 文本问答成功，并记录正确 Runtime 和模型用量。
+2. Ask 可以读取工作区，但写入被拒绝，且不会弹出权限对话框。
+3. Execute 可以在工作区创建测试文件。
+4. Execute 越界操作先被拒绝，再对完全相同的重试自动给予单次授权，全程不弹出审批。
+5. 不匹配的重试、Ask 和 delegation 不能换路径或重复绕过。
+6. 取消长请求后不再产生文本，并可继续使用其他 Session。
+7. 两个 Session 可并行，事件不会串线。
+8. 释放会话和关闭应用后没有残留 Harness 或工具进程。
+9. 从全新用户设置流程启用一个 3D 游戏 Skill 和实际本地或开放 MCP，工具事件能够证明二者确实被调用。
+10. Harness 生成的 3D 游戏项目可以安装、启动和实际游玩，包含 3D 渲染、玩家控制、目标和反馈，浏览器无关键错误。
+
+测试不得打印、快照或提交 API Key。测试创建的文件只能位于专用临时工作区，并在确认可再现后清理。
+
+### 17.4 项目验证
+
+源码完成后必须运行：
+
+```text
+npm test
+npm run typecheck
+npm run lint
+npm run build
+```
+
+涉及发布资源后，还要按可用原生平台运行聚焦的 `release:package` 验证。无法在当前主机执行的目标必须由六平台 CI 验证。
+
+## 18. 验收标准
+
+功能只有同时满足以下条件才算完成：
+
+- `deepseek-harness` 可被保存、选择、检测和显示。
+- Runtime 详情卡内显示状态、路径、版本和沙箱强制程度。
+- Skills 与 MCP 设置页可把能力分配给 DeepSeek Harness，布局、键盘语义、文案和保存回显通过真机检查。
+- Ask 写入测试在 Runtime 边界失败。
+- Execute 工作区内写入成功。
+- 越界写入只有同一操作获得自动单次授权后才能执行一次，且不弹出审批。
+- 取消、超时、切换 Runtime 和退出应用均能回收进程。
+- 多会话不串流、不串权限请求、不串用量。
+- 用户 DSH 配置、`.env`、遥测和 Web UI 未被加载。
+- API Key 不进入 Renderer、配置文件、日志、错误文本或测试产物。
+- 全量测试、类型检查、Lint 和生产构建通过。
+- 真实 OpenAI 兼容 Chat Completions 请求成功。
+- 真实请求调用已分配 Skill 和 MCP，并生成、启动和实际游玩一个可用的 3D 游戏项目。
+- 新增第三方许可证和发布校验完整。
+
+## 19. 已知限制
+
+- DeepSeek Harness 底层库当前是 RC，但 GoodBuddy 不自动跟随升级；每次升级都可能要求同步修改内部控制面。
+- Windows ACL 和部分 Linux Landlock 环境只能提供部分强制执行。
+- 首版不恢复 Harness 原生 Session，Runtime 重启后由 GoodBuddy 历史重建。
+- 首版不支持图片、知识库、浏览器工具和 Harness Subagent；MCP 仅支持用户分配、Main 代理和 Execute 自动单次授权路径。
+- 推理、工具和用量扩展属于 GoodBuddy 协议，不是标准 ACP 保证。
+- 不支持 DSH 插件、市场包、用户 profile 或自定义 Host。
+
+## 20. 自维护与升级策略
+
+GoodBuddy 对该 Runtime 采用内部维护策略：
+
+1. 当前通过验证的 Host、控制协议和依赖锁定随 GoodBuddy 一起版本化。
+2. 不自动跟随 DSH RC、插件 ABI、profile 格式或市场元数据变化。
+3. 升级前审查实际用户收益、上游 diff、沙箱与工具语义、协议行为、依赖闭包和许可证。
+4. 六个平台的单元、假模型、UtilityProcess、沙箱和真实模型门禁全部通过后才能更新基线。
+5. 若上游方向不再满足 GoodBuddy 用户需求或安全边界，允许维护兼容补丁、替换单个底层包，或逐步移除 DSH 依赖；`goodbuddy/*` 内部协议保持由 GoodBuddy 控制。
+6. 不以进入官方插件目录、适配市场机制或服务非 GoodBuddy 客户端作为目标。
+
+## 21. 备选方案记录
+
+### 21.1 每次调用 `dsh --profile headless`
+
+未采用。它适合一次性任务，但不能满足流式事件、多会话、细粒度取消、权限回传和低延迟复用。
+
+### 21.2 只使用官方 ACP 插件
+
+未采用。取消和一次性权限选择符合需求，但缺少工具、推理、用量和会话释放事件。
+
+### 21.3 只使用官方 SDK JSON-RPC
+
+未采用。事件更完整，但单轮取消和权限回传能力不足。
+
+### 21.4 把全部安全逻辑放进 Harness 子进程
+
+未采用。Harness 子进程属于不可信执行面，不能拥有最终模式授权策略、加密设置和进程回收权限。
+
+### 21.5 把全部控制适配放在 Main
+
+未采用。Main 无法可靠观察 Cordis 内部 Session、Tool、Usage 和权限 seam，只能得到不完整的外部进程行为。
+
+当前选择的双层内部控制面放弃标准 DSH 插件形态，只复用锁定的底层库，并维持 GoodBuddy 的可信 Main 控制权。

+## 文档信息
+
+| 项目 | 内容 |
+| --- | --- |
+| 状态 | 设计中 |
+| 版本 | 0.1 |
+| 日期 | 2026-08-13 |
+| 依赖 | [自动化、监督与记忆平台总体设计](./automation-platform-architecture.md) |
+
+## 1. 背景
+
+GoodBuddy 当前的定时任务支持单次、每日和每周触发固定 Ask 提示，并保存任务和成果；
+智能心跳支持每日或每周回顾有界的会话、任务和已确认记忆。两者尚不能表达事件触发、
+目标、成功标准、预算、停止条件和安全恢复。
+
+## 2. 产品边界
+
+| 类型 | 用户意图 | 是否形成循环 |
+| --- | --- | --- |
+| 定时任务 | 在指定时间执行已知操作 | 否 |
+| 事件任务 | 当明确事件发生时执行已知操作 | 否 |
+| 目标任务 | 在预算内持续推进到可验证结果 | 是 |
+
+智能心跳是特殊的定时观察任务。并行实验属于独立产品。
+
+## 3. 已确认的产品决策
+
+1. 自动化定义与每次运行分离，编辑计划不改变已启动 Run。
+2. 第一阶段保留现有定时任务的 Ask 限制，Execute 分阶段开放。
+3. Execute 自动化不能因无人值守而绕过现有审批、沙箱和工具控制。
+4. 应用退出后不承诺继续运行，重启后只进行状态恢复和错过执行结算。
+5. 目标任务必须有成功标准，以及预算或人工结束条件。
+6. 模型可以提出计划，确定性状态机负责预算、停止、权限和恢复。
+7. 同一计划默认最多一个活动 Run。
+8. 后台任务可被背压延后，不能挤占用户正在等待的前台请求。
+9. 结果未知的外部副作用步骤不自动重试。
+10. 项目、知识库、记忆、目录和工具范围在保存和运行页持续可见。
+
+## 4. 目标
+
+- 支持单次、每日、每周、每月、工作日和受限 Cron。
+- 支持任务完成、失败、会话完成等内部事件触发。
+- 允许用户用自然语言生成结构化草稿，再检查后启用。
+- 为目标任务建立有界的“观察、计划、行动、评估”循环。
+- 提供幂等、租约、错过执行、取消、重试、恢复、预算和审计。
+- 为后续并行实验和持续学习复用协议、指标和运行基础。
+
+## 5. 非目标
+
+- 第一阶段不提供任意节点、脚本和循环的通用 DAG 编辑器。
+- 不允许模型编写并执行任意 Shell、SQL 或无限频率 Cron。
+- 不支持应用退出后通过未安装的系统服务继续运行。
+- 不把“模型说完成了”作为唯一成功标准。
+- 不允许自动任务静默修改自身权限、触发器或预算。
+- 不在目标循环中无限创建子任务或专家。
+
+## 6. 创建与启用
+
+用户可以先输入自然语言意图：
+
+```text
+每周五下午 5 点总结本项目本周完成和失败的任务，
+列出下周三个优先事项，不要修改文件。
+```
+
+模型只生成草稿：
+
+- 名称、说明和自动化类型。
+- 触发器。
+- 目标、输出和成功标准建议。
+- 工作模式和 Runtime 建议。
+- 数据范围。
+- 预算、停止条件和通知。
+
+草稿不能自动启用。用户必须检查结构化配置。
+
+### 6.1 所有计划必填
+
+- 名称、范围和类型。
+- 触发器。
+- 工作模式和 Runtime。
+- 输入、输出和通知。
+- 预算和数据保留。
+- 知识库、记忆、目录和工具范围。
+
+### 6.2 目标任务额外必填
+
+- 目标描述。
+- 至少一个成功标准。
+- 约束。
+- 最大轮数或截止时间。
+- 每轮评估方式。
+- 无进展处理。
+
+### 6.3 启用前检查
+
+- 时区和下一次运行时间可解析。
+- 项目、目录、Runtime 和模型可用。
+- Ask 没有写入或外部副作用要求。
+- Execute 的工具和审批范围明确。
+- 预算不是无界值。
+- 事件来源存在且已启用。
+- 目标任务存在停止条件。
+
+## 7. 触发器
+
+### 7.1 时间触发
+
+```ts
+type TimeTrigger =
+  | { type: 'once'; at: string; timezone: string }
+  | { type: 'daily'; localTime: string; timezone: string }
+  | {
+      type: 'weekly'
+      weekdays: number[]
+      localTime: string
+      timezone: string
+    }
+  | {
+      type: 'monthly'
+      day: number | 'last'
+      localTime: string
+      timezone: string
+    }
+  | {
+      type: 'cron'
+      expression: string
+      timezone: string
+    }
+```
+
+受限 Cron 只允许五字段，不支持秒、年份、宏、`L`、`W`、`#` 或供应商扩展。
+Main 负责解析并展示未来五次运行时间，默认最小间隔为 15 分钟。
+
+### 7.2 事件触发
+
+第二阶段支持：
+
+- `conversation.completed`
+- `task.completed`
+- `task.failed`
+- `artifact.created`
+- `knowledge.sync.completed`
+- `magic_note.updated`
+
+事件触发必须配置来源范围、确定性过滤、去重窗口、冷却时间和并发上限。
+基础匹配不调用模型。
+
+### 7.3 手动触发
+
+- “立即运行”创建独立 Run，不改变下次计划时间。
+- 多次点击使用调用级幂等键去重。
+- 未保存的变更需先保存为新版本，或明确使用当前已发布版本。
+
+### 7.4 错过执行
+
+| 策略 | 行为 |
+| --- | --- |
+| `skip` | 记录跳过，不补跑 |
+| `run_once` | 无论错过多少次，只补一次 |
+| `catch_up_bounded` | 在数量和时间窗口上限内补跑 |
+
+有界补跑默认最多 3 次、最多回溯 7 天。补跑同样受并发和预算控制。
+
+### 7.5 时区和夏令时
+
+- 保存 IANA 时区，不保存固定 UTC 偏移。
+- 春季不存在的本地时间在当日第一个有效分钟运行。
+- 秋季重复时间只运行一次。
+- 系统时区变化不自动修改计划时区。
+- UI 显示计划时区与本机时区差异。
+
+## 8. 目标任务
+
+### 8.1 目标模型
+
+```ts
+type AutomationObjective = {
+  statement: string
+  successCriteria: SuccessCriterion[]
+  constraints: Constraint[]
+  deadline?: string
+}
+
+type SuccessCriterion =
+  | { type: 'artifact_exists'; kind: string; minimumCount: number }
+  | { type: 'task_state'; taskId: string; expected: 'completed' }
+  | {
+      type: 'metric_threshold'
+      metric: string
+      operator: string
+      value: number
+    }
+  | { type: 'checklist'; items: string[] }
+  | { type: 'human_review' }
+  | {
+      type: 'model_rubric'
+      rubricId: string
+      minimumScore: number
+    }
+```
+
+模型 Rubric 不能是唯一标准，除非任务本质是开放内容评价且 UI 明确标注。
+
+### 8.2 有界循环
+
+```text
+Observe
+  → Plan next action
+  → Check permissions and budget
+  → Act or request approval
+  → Evaluate progress
+  → Complete, pause, revise or continue
+```
+
+每轮持久化观察摘要、下一步、实际任务或工具、成果、指标、预算、进展状态和
+Supervisor 决策。只保存专门生成的结构化理由摘要，不保存隐藏推理。
+
+### 8.3 无进展检测
+
+出现任一情况进入 `attention_required`：
+
+- 连续两轮没有指标改善或新成果。
+- 重复提出相同下一步。
+- 连续失败达到上限。
+- 需要的输入或权限不可用。
+- 剩余预算不足。
+- Supervisor 判定目标或前提需要澄清。
+
+默认暂停并请求用户选择，不自动扩大范围。
+
+### 8.4 计划修订
+
+目标任务可以建议修改步骤、缩小目标、请求输入、增加预算或改变 Runtime。
+修改范围、预算、Runtime、工作模式或权限必须用户确认，并形成新版本或 Run 修订记录。
+
+## 9. 工作模式与审批
+
+### 9.1 Ask
+
+- 默认只读。
+- 只使用明确开放的只读数据工具。
+- 不写文件、不执行命令、不发送消息、不修改远程数据。
+- 输出进入成果和通知。
+
+### 9.2 Execute
+
+按以下顺序开放：
+
+1. 有人值守，沿用逐工具审批。
+2. 预批准低风险工具和参数范围。
+3. 经过专项验证的内置无人值守模板。
+
+即使预批准，也不能扩大目录和能力。高风险或越界动作进入 `waiting_approval`。
+密码输入、支付、授权、删除、公开发布和生产变更不能预批准。
+
+## 10. 预算与背压
+
+```ts
+type AutomationBudget = {
+  maximumDurationMs: number
+  maximumIterations: number
+  maximumModelCalls: number
+  maximumInputTokens?: number
+  maximumOutputTokens?: number
+  maximumToolCalls: number
+  maximumChildTasks: number
+  maximumArtifactBytes: number
+  maximumConcurrentChildren: number
+}
+```
+
+建议默认值：
+
+| 类型 | 最长时间 | 模型调用 | 子任务并发 |
+| --- | --- | --- | --- |
+| 定时 Ask | 5 分钟 | 4 | 1 |
+| 心跳回顾 | 5 分钟 | 2 | 0 |
+| 目标 Ask | 30 分钟 | 12 | 2 |
+| 目标 Execute | 30 分钟 | 12 | 1 |
+
+前台请求优先。后台使用独立并发池，达到上限时排队。高负载时低优先级心跳和维护任务
+记录为 `deferred`，压力解除后有界恢复，不能一次性释放全部积压。
+
+## 11. 重试、恢复与取消
+
+| 失败类型 | 行为 |
+| --- | --- |
+| 瞬时网络或限流 | 指数退避，有界重试 |
+| 模型格式错误 | 最多一次结构化修复 |
+| 配置或权限错误 | 不重试，等待修复 |
+| 无副作用的确定性工具失败 | 按工具策略重试 |
+| 结果未知或已有外部副作用 | 不自动重试 |
+
+应用退出时停止声明新 Run，取消可取消工作，活动 Run 标记为 `interrupted` 并保存安全
+检查点。重启后用户可恢复、复制剩余步骤或放弃；结果未知步骤必须先人工核实。
+
+暂停 Plan 只阻止新 Run，不终止当前 Run。取消 Run 必须传播到子任务和 Runtime，
+但不能把已发生的外部副作用假装撤销。
+
+## 12. 输出与通知
+
+输出可保存为文字或文件成果、创建后续任务建议，或仅通知。后续可支持更新指定魔法笔记。
+
+通知事件：
+
+- Run 完成或失败。
+- 等待审批。
+- Supervisor 要求关注。
+- 目标达成。
+- 预算达到 80%。
+- 连续无进展。
+
+同一事件不同时显示重复页内横幅和全局通知。
+
+## 13. 信息架构
+
+计划列表显示名称、类型、范围、启用状态、下次运行、最近 Run、目标状态和需要关注数量。
+
+计划详情页签：
+
+- 概览。
+- 目标与协议。
+- 触发器。
+- 权限与预算。
+- 运行历史。
+
+Run 详情展示总览、时间线、任务、审批、监督、指标、证据、成果以及实际读取的知识和记忆。
+
+## 14. 数据模型建议
+
+```ts
+type AutomationPlan = {
+  id: string
+  projectId?: string
+  kind: 'scheduled_task' | 'heartbeat_review' | 'goal_loop'
+  name: string
+  description: string
+  status: 'draft' | 'active' | 'paused' | 'archived'
+  currentVersion: number
+  nextRunAt?: string
+  createdAt: string
+  updatedAt: string
+}
+
+type AutomationPlanVersion = {
+  planId: string
+  version: number
+  trigger: TriggerPolicy
+  objective?: AutomationObjective
+  protocol: ExecutionProtocol
+  budget: AutomationBudget
+  approvalPolicy: ApprovalPolicy
+  supervisorPolicy?: SupervisorPolicy
+  memoryBinding: MemoryBinding
+}
+```
+
+状态、范围、下次运行、版本和索引字段使用显式列；版本化协议可以使用经过共享 Schema
+验证的 JSON。
+
+## 15. 安全要求
+
+1. 所有输入由共享 Zod Schema 验证。
+2. Main 重新验证项目、目录、Runtime、工具、知识库和记忆分区归属。
+3. Renderer 不可直接声明 Run 完成或批准工具。
+4. 自动化提示、事件、记忆和成果都视为不可信数据。
+5. 事件过滤不执行用户 JavaScript、SQL 或无限复杂表达式。
+6. Cron 有复杂度和最小间隔限制。
+7. 自动化不能读取未绑定知识库、桌面上下文或其他项目记忆。
+8. 日志和通知对私人内容、密钥和工具输出有界脱敏。
+
+## 16. 实施顺序
+
+1. 统一现有 Schedule 和 Heartbeat 的 Run 视图。
+2. 增加幂等、租约、月度、工作日、受限 Cron、错过执行和未来运行预览。
+3. 建立内部持久事件、过滤、冷却和去重，首期只支持 Ask。
+4. 上线目标 Ask、有界循环、无进展检测和人工暂停。
+5. 接入会话监督。
+6. 再开放有人值守和预批准低风险 Execute。
+
+## 17. 验收标准
+
+- [ ] 支持单次、每日、每周、每月、工作日和受限 Cron。
+- [ ] UI 显示计划时区和未来五次运行时间。
+- [ ] 夏令时不会造成计划漂移或双跑。
+- [ ] 同一计划同一时间点只产生一个 Run。
+- [ ] 错过执行按配置跳过、补一次或有界补跑。
+- [ ] 手动运行不改变下次计划时间。
+- [ ] Ask 自动化在 Runtime 边界拒绝写工具和外部副作用。
+- [ ] 目标任务必须有成功标准和停止条件。
+- [ ] 每轮都有观察、行动、评估和预算记录。
+- [ ] 连续无进展会暂停，不无限循环。
+- [ ] 达到预算使用 `budget_exceeded`，不伪装为成功。
+- [ ] 设置变化不影响已启动 Run。
+- [ ] 重启后不自动重放结果未知的副作用步骤。
+- [ ] 后台任务排队时不挤占前台模型请求。

+# 自动化、监督与记忆平台总体设计
+
+## 文档信息
+
+| 项目 | 内容 |
+| --- | --- |
+| 状态 | 设计中 |
+| 版本 | 0.1 |
+| 日期 | 2026-08-13 |
+| 适用产品 | GoodBuddy 桌面端 |
+| 文档角色 | 自动任务、目标、并行实验、会话监督、分区记忆与持续学习的总纲 |
+
+## 1. 背景
+
+GoodBuddy 当前已经具备若干长期助手能力，但它们仍是彼此分离的功能：
+
+1. 定时任务支持单次、每日和每周触发，创建 Ask 任务并保存任务和成果。
+2. 智能心跳支持全局或项目范围的每日、每周回顾，读取有界会话、任务和已确认记忆，
+   生成摘要、记忆建议和后续任务。
+3. 专家子任务支持有限并发和只读综合，但没有实验变量、重复运行、统一指标和结果晋升。
+4. 记忆已有全局、项目、会话三种作用域，以及偏好、事实、摘要、流程四种类型，
+   但检索、来源、时态、冲突和运行级隔离仍不完整。
+5. 魔法笔记已经提供“内容旁持续出现 AI 评论”的交互，可作为会话监督的体验参考，
+   但它只分析笔记或待办，不观察会话和任务运行。
+
+如果继续把更多能力加入“智能心跳”，心跳将同时承担调度、总结、执行、监督、学习和
+记忆管理，最终无法解释一次后台行为为什么发生、读取了什么、是否越权、产生了什么影响。
+
+本设计将这些能力统一到一个平台模型中，同时保留不同产品的清晰边界。
+
+## 2. 核心产品判断
+
+### 2.1 不把心跳升级成万能后台 Agent
+
+智能心跳应继续承担周期性观察和回顾，不直接成为所有自动化的宿主。
+
+- 定时任务解决“何时执行一个已知任务”。
+- 目标任务解决“围绕结果持续规划和推进”。
+- 并行实验解决“隔离多个候选并用相同标准比较”。
+- 会话监督解决“独立观察并在必要时评论、告警或暂停”。
+- 记忆系统解决“哪些经验可以在什么范围内被未来运行读取”。
+- 持续学习解决“候选经验如何经过评估后改变未来行为”。
+
+这些能力可以共享调度、运行、证据、预算和审计基础，但不能共享一段不断膨胀的提示词。
+
+### 2.2 增加会话监督，但不把它等同于第二个聊天 Agent
+
+建议新增会话监督功能，并借鉴魔法笔记的右侧 AI 评论流：
+
+- 默认只观察和评论，不替用户发言。
+- 只依据可见消息、工具事件、任务状态、成果和目标进行判断。
+- 不读取或展示模型隐藏推理。
+- 评论必须引用具体消息、步骤或证据。
+- 模型监督可以建议暂停，只有确定性安全规则或用户预先批准的门禁才能自动暂停。
+- 监督器不能自动批准工具、扩大目录、跨项目读取记忆或修改安全策略。
+
+### 2.3 先做分区和来源，再做知识图谱
+
+GoodBuddy 当前最需要的不是立即引入重型图数据库，而是保证：
+
+1. 运行只能读取明确允许的记忆分区。
+2. 并行实验的各个 Run 不共享可变记忆。
+3. 每条记忆知道来自哪次会话、任务、监督判断或实验结果。
+4. 新事实与旧事实冲突时保留时态和证据，不静默覆盖。
+5. 记忆进入模型上下文前经过范围、状态、敏感度和预算过滤。
+
+SQLite、FTS 和可选本地向量已经足够支撑第一阶段。只有出现明确的关系追踪和跨实体查询
+需求后，才考虑时间知识图谱。
+
+### 2.4 学习必须有评估门和回滚
+
+“生成一条总结并保存”不等于持续学习。只有当候选经验通过回放或实验验证，并能安全改变
+未来行为时，才构成学习闭环。
+
+初期自动学习只允许产生可审查候选，不允许自动修改：
+
+- 工具权限和审批策略。
+- Electron 安全边界。
+- 项目根目录和数据访问范围。
+- Runtime 沙箱。
+- 系统级提示词。
+- 远程消息发送或其他外部副作用策略。
+
+## 3. 目标
+
+### 3.1 用户目标
+
+- 用统一入口创建定时、事件、目标和实验型自动任务。
+- 清楚知道自动任务的触发原因、当前目标、运行状态、预算和停止条件。
+- 在一个工作台中观察多个候选运行，并追溯结论到原始证据。
+- 为重要会话启用独立监督，及时发现偏题、遗漏、矛盾、证据不足和风险。
+- 知道每条记忆属于哪个范围、从哪里产生、何时有效以及被哪些运行使用。
+- 审查、批准、拒绝或回滚系统提出的记忆、模板和策略改进。
+
+### 3.2 产品目标
+
+- 复用现有 Project、Conversation、Task、Run、Artifact、Approval 和 Notification 能力。
+- 为所有后台工作提供统一的幂等、租约、恢复、取消、预算和审计语义。
+- 保持 Ask 只读，Execute 继续经过现有能力和审批控制。
+- 保持本地优先，应用退出后不虚假承诺后台持续执行。
+- 保证项目、会话、自动化和实验 Run 之间的记忆隔离。
+- 先建立可观测和可评估能力，再允许任何形式的自动行为改变。
+
+## 4. 非目标
+
+本组设计不包含：
+
+- 将 GoodBuddy 变为需要常驻服务器、Redis 或云端控制面的多租户平台。
+- 在应用退出后依靠未安装的系统服务继续运行任务。
+- 默认允许无人值守高风险 Execute。
+- 让模型自行扩大工具、目录、知识库、记忆或网络访问范围。
+- 允许多个实验 Run 并发修改同一个用户工作区。
+- 记录键盘、持续录屏或静默监控其他应用。
+- 把隐藏推理链作为监督、记忆或审计数据保存。
+- 初期直接建设通用可视化工作流 DAG 编辑器。
+- 将模型评分当作没有误差的客观真值。
+
+## 5. 统一领域模型
+
+### 5.1 核心实体
+
+```text
+AutomationPlan
+  ├─ TriggerPolicy
+  ├─ ObjectiveSet
+  ├─ ExecutionProtocol
+  ├─ BudgetPolicy
+  ├─ ApprovalPolicy
+  ├─ SupervisorPolicy
+  └─ MemoryBinding
+       │
+       └─ AutomationRun
+            ├─ Task / Child Task
+            ├─ Observation
+            ├─ SupervisorDecision
+            ├─ Artifact
+            ├─ Metric
+            └─ MemoryCandidate
+```
+
+| 实体 | 职责 |
+| --- | --- |
+| `AutomationPlan` | 用户可编辑的长期定义，描述做什么、为何做、何时做和允许做什么 |
+| `TriggerPolicy` | 手动、时间、事件或条件触发，以及错过执行策略 |
+| `ObjectiveSet` | 成功标准、优化指标、约束和停止条件 |
+| `ExecutionProtocol` | 本次运行冻结的提示、步骤模板、变量、Runtime、工具和数据范围 |
+| `BudgetPolicy` | 最大耗时、模型调用、Token、工具次数、子任务数、成果大小和并发 |
+| `ApprovalPolicy` | 哪些动作可自动执行、哪些等待批准、哪些禁止 |
+| `SupervisorPolicy` | 观察维度、触发频率、干预级别和确定性门禁 |
+| `MemoryBinding` | 运行可读取和可写入哪些记忆分区 |
+| `AutomationRun` | 一次触发产生的不可变运行快照和聚合状态 |
+| `Observation` | 对消息、步骤、工具、指标或系统状态的结构化观察 |
+| `SupervisorDecision` | `continue`、`comment`、`warn`、`request_review`、`pause` 或 `stop` |
+| `Metric` | 可复现的运行指标及其计算来源 |
+| `MemoryCandidate` | 尚未进入未来上下文的候选经验 |
+
+### 5.2 自动化类型
+
+`AutomationPlan.kind` 第一阶段使用有限枚举，而不是任意工作流：
+
+| 类型 | 说明 |
+| --- | --- |
+| `scheduled_task` | 到点运行一个固定任务 |
+| `heartbeat_review` | 周期性观察会话、任务和记忆，输出回顾和建议 |
+| `goal_loop` | 围绕目标重复执行“观察、计划、行动、评估” |
+| `experiment` | 生成隔离候选 Run，按统一协议评估和比较 |
+
+会话监督不是独立执行任务。它是可附着到 Conversation、Task、AutomationRun 或
+Experiment 的 `SupervisorPolicy` 和监督会话。
+
+### 5.3 运行快照
+
+每次启动必须冻结：
+
+- Plan 版本。
+- 项目和工作目录。
+- Runtime 和模型配置引用。
+- 工作模式。
+- 提示和变量。
+- 工具、Skills、MCP 和知识库范围。
+- 可读、可写记忆分区。
+- 监督策略和评估器版本。
+- 预算和并发限制。
+- 审批策略。
+
+运行开始后的设置变化只影响下一次 Run。用户可以查看当前 Run 与最新 Plan 的差异。
+
+## 6. 统一状态模型
+
+### 6.1 Plan 状态
+
+```text
+draft → active ↔ paused → archived
+```
+
+- `draft`：未通过配置校验，不能自动触发。
+- `active`：可以被触发。
+- `paused`：保留定义和历史，不产生新 Run。
+- `archived`：只读保留，不能恢复运行，复制后可继续使用。
+
+### 6.2 Run 状态
+
+```text
+queued
+  → running
+  → waiting_approval
+  → paused
+  → evaluating
+  → completed
+
+任意活动状态
+  → failed | cancelled | interrupted | budget_exceeded | superseded
+```
+
+规则：
+
+- `completed` 只表示协议成功结束，不自动表示目标达成。
+- `goalStatus` 独立为 `met`、`not_met`、`inconclusive` 或 `not_applicable`。
+- 应用退出时活动 Run 标记为 `interrupted`，不自动重放有副作用步骤。
+- `waiting_approval` 不占用 LLM 并发配额。
+- 预算耗尽必须使用 `budget_exceeded`，不能伪装为普通失败。
+
+### 6.3 Supervisor 状态
+
+```text
+inactive → observing → attention_required → paused → resolved
+```
+
+监督状态不覆盖 Run 状态。Run 可以仍在运行但存在 `attention_required`，也可以因确定性门禁
+进入 `paused`。
+
+## 7. 统一运行循环
+
+### 7.1 调度与执行分离
+
+```text
+Trigger
+  → AutomationCoordinator 声明 Run
+  → RunQueue 按优先级和预算排队
+  → AutomationExecutor 创建 Task
+  → Runtime 执行
+  → Supervisor 观察
+  → Evaluator 计算指标
+  → 结果、证据和候选记忆入库
+  → 用户审查或后续 Run
+```
+
+`AutomationCoordinator` 只负责触发、声明和恢复，不直接调用模型。执行仍通过任务和 Runtime
+边界完成。
+
+### 7.2 优先级
+
+默认优先级从高到低：
+
+1. 用户正在等待的前台对话。
+2. 用户手动启动的 Run。
+3. 等待批准后恢复的 Run。
+4. 到期定时任务。
+5. 目标循环和实验 Run。
+6. 心跳回顾、记忆巩固和维护。
+
+后台任务必须可被背压延后。延后记录为 `deferred`，不得丢失，也不得在系统恢复空闲时一次性
+释放全部积压。
+
+### 7.3 幂等和租约
+
+- 每次计划触发使用 `planId + scheduledFor + planVersion` 形成幂等键。
+- 手动触发使用调用方提供的单次幂等键。
+- Run 和长步骤使用租约，租约过期后才能恢复或重试。
+- 有外部副作用的步骤还需要工具级幂等键，无法确认结果时进入
+  `outcome_unknown`，不得自动重试。
+- 同一个 Plan 可以限制最大活动 Run 数，默认 1。
+
+## 8. 触发模型
+
+### 8.1 支持顺序
+
+| 阶段 | 触发类型 |
+| --- | --- |
+| 第一阶段 | 手动、单次、每日、每周、每月、受限 Cron |
+| 第二阶段 | 应用启动、会话完成、任务完成或失败、文件同步完成、变量变化 |
+| 后续 | 用户定义的组合条件和外部受信任事件 |
+
+事件触发必须来自 Main 进程内的持久事件，不允许 Renderer 临时事件直接启动高影响自动化。
+
+### 8.2 错过执行策略
+
+| 策略 | 行为 |
+| --- | --- |
+| `skip` | 记录跳过，不补跑 |
+| `run_once` | 无论错过多少次，只补一次 |
+| `catch_up_bounded` | 在数量和时间窗口上限内补跑 |
+
+默认：
+
+- 日常摘要使用 `run_once`。
+- 高频事件使用 `skip` 或事件去重。
+- 不允许无限补跑。
+
+## 9. 目标、协议和实验的关系
+
+```text
+目标：想得到什么结果
+协议：用什么固定方法尝试
+运行：协议的一次执行
+实验：同一问题下多个隔离协议或变量组合的运行集合
+监督：运行过程中独立判断是否偏离目标、违反约束或需要人工介入
+记忆：运行可读的历史经验，以及运行结束后提出的候选经验
+```
+
+关键规则：
+
+- 没有可计算或可审查成功标准的目标，不允许宣称“已完成目标”。
+- 实验的最佳结果只在成功 Run 中选择。
+- 全部 Run 失败时，实验状态为失败，不生成伪最佳结果。
+- 模型生成的实验协议必须先由用户审查，或在只读、低成本模板中明确启用自动接受。
+- 实验结果不能直接修改生产自动化，只能创建候选版本。
+
+## 10. 监督边界
+
+监督分为两层：
+
+### 10.1 确定性监督
+
+由代码执行，适合：
+
+- 权限、目录和工具白名单。
+- Token、耗时、并发和输出大小预算。
+- JSON Schema、状态机和幂等约束。
+- 明确的停止条件和指标阈值。
+- 数据分区和跨范围访问。
+
+确定性监督可以阻止、暂停或终止运行。
+
+### 10.2 模型监督
+
+适合：
+
+- 目标偏移。
+- 计划遗漏。
+- 结论与证据不一致。
+- 多个候选之间的定性差异。
+- 用户可能需要澄清的歧义。
+- 质量、表达和风险评论。
+
+模型监督默认只评论或请求关注。它不能替代确定性安全边界，也不能自动批准高风险动作。
+
+## 11. 记忆边界
+
+### 11.1 计划读取链
+
+运行只读取显式绑定的分区。推荐优先级：
+
+```text
+当前 Run
+→ 当前 Automation
+→ 当前 Conversation（如有关联）
+→ 当前 Project
+→ Global
+```
+
+每一层都有独立结果数和字符预算。低层记忆不能通过同名内容自动覆盖高层记忆，
+冲突必须被标记并交给上下文组装器处理。
+
+### 11.2 写入规则
+
+- Run 只能直接写入自己的运行分区和候选区。
+- 向 Automation、Project 或 Global 晋升需要评估或用户确认。
+- 实验 Run 不能直接互相读取运行记忆。
+- Supervisor 的判断保存为观察或候选，不自动变成事实。
+- 被拒绝的候选保留摘要指纹，避免重复建议，同时不进入模型上下文。
+
+## 12. 信息架构
+
+建议将现有“智能心跳”逐步扩展为“自动化中心”，但保留心跳作为一种计划：
+
+```text
+自动化中心
+├─ 概览
+│  ├─ 正在运行
+│  ├─ 等待审批
+│  ├─ 需要关注
+│  └─ 最近结果
+├─ 计划
+│  ├─ 定时任务
+│  ├─ 智能心跳
+│  ├─ 目标任务
+│  └─ 实验
+├─ 运行
+│  ├─ 时间线
+│  ├─ 任务与步骤
+│  ├─ 监督记录
+│  ├─ 指标与证据
+│  └─ 成果
+├─ 建议
+│  ├─ 记忆候选
+│  ├─ 后续任务
+│  └─ 学习候选
+└─ 设置
+   ├─ 全局预算
+   ├─ 后台优先级
+   ├─ 通知
+   └─ 数据保留
+```
+
+会话页面增加可折叠“监督”右栏，与任务、上下文和成果并列，或在已有右侧工作栏中新增页签。
+
+## 13. 安全与隐私
+
+1. Ask 在 Runtime 边界保持只读，而不只是提示词要求只读。
+2. Execute 继续通过现有审批、沙箱、工具和目录控制。
+3. 无人值守只允许用户显式批准的能力集合；遇到未预授权动作时进入等待审批。
+4. Supervisor、Evaluator 和 Heartbeat 都把消息、工具输出、记忆和成果视为不可信数据。
+5. 监督器不能读取隐藏推理，只能读取产品允许持久化和展示的事件。
+6. 所有跨分区读取由 Main 根据绑定关系决定，Renderer 不能提交任意分区 ID。
+7. 记忆和监督证据不得包含密钥、认证头、Cookie、完整私有文件或未经限制的工具输出。
+8. 自动化产生的通知默认隐藏私人内容。
+9. 应用退出时停止调度和新执行，持久化中断状态，释放 Runtime 和租约。
+10. 清除项目时按外键和显式事务清理其计划、运行、运行分区、监督记录和候选，
+    不影响 Global 或其他项目。
+
+## 14. 可观测性
+
+每个 Run 至少展示：
+
+- 触发来源和计划版本。
+- 计划目标和当前 `goalStatus`。
+- Runtime、工作模式和工作目录。
+- 实际读取的知识库与记忆分区。
+- 实际调用的模型、Token、工具、耗时和成果大小。
+- 当前预算和剩余预算。
+- 任务、步骤和子任务状态。
+- Supervisor 评论、证据、严重度和处理结果。
+- 评估器版本、指标和证据。
+- 产生的候选记忆或学习产物。
+- 重试、延后、中断和恢复原因。
+
+不得只显示一个模糊的“自动化成功率”而隐藏失败 Run、跳过 Run 或无结论 Run。
+
+## 15. 建议的数据模型增量
+
+以下为设计建议，字段在实现前仍需共享 Zod Schema 和 SQLite 迁移细化：
+
+```text
+automation_plans
+automation_plan_versions
+automation_triggers
+automation_runs
+automation_run_events
+automation_metrics
+automation_observations
+supervisor_sessions
+supervisor_decisions
+memory_namespaces
+memory_candidates
+learning_artifacts
+evaluation_cases
+evaluation_results
+experiments
+experiment_variants
+experiment_runs
+```
+
+现有 `schedules`、`schedule_runs`、`heartbeat_configs`、`heartbeat_runs`、
+`heartbeat_entries`、`tasks` 和 `runs` 不应一次性重写。迁移顺序应先增加统一只读视图和
+关联字段，再逐步让新计划使用统一模型。
+
+## 16. 分阶段实施
+
+### 阶段 0：统一术语和可观测性
+
+- 固定 Plan、Run、Goal、Protocol、Supervisor、Observation、Memory Candidate 等概念。
+- 为现有定时任务、心跳和专家子任务建立统一活动视图。
+- 补充触发来源、运行版本、预算和读写范围展示。
+
+### 阶段 1：调度与运行基础
+
+- 统一 Run 声明、幂等、租约、恢复和错过执行策略。
+- 增加月度和受限 Cron。
+- 增加后台优先级与并发预算。
+- 保持现有任务执行器不变。
+
+### 阶段 2：会话监督与分区记忆
+
+- 上线评论型会话监督。
+- 增加 Automation 和 Run 记忆分区。
+- 建立来源、证据、时态、冲突和晋升流程。
+
+### 阶段 3：目标任务
+
+- 增加目标、成功标准、约束、预算和停止条件。
+- 支持有界的观察、计划、行动、评估循环。
+- 默认 Ask 或需要逐步审批的 Execute。
+
+### 阶段 4：并行实验
+
+- 变量和运行隔离。
+- 候选、重复、指标、证据、失败结算和最佳结果选择。
+- 复用现有任务和受限子专家并发。
+
+### 阶段 5：持续学习
+
+- 先建立回放集和评估门。
+- 再增加候选、Shadow、晋升、监控、衰减和回滚。
+- 初期只晋升记忆和自动化模板，不自动改变安全策略。

+# 持续学习与评估门 PRD
+
+## 文档信息
+
+| 项目 | 内容 |
+| --- | --- |
+| 状态 | 设计中，远期能力 |
+| 版本 | 0.1 |
+| 日期 | 2026-08-13 |
+| 依赖 | [自动化平台总体设计](./automation-platform-architecture.md)、[并行实验 PRD](./parallel-experiments-prd.md)、[分区记忆 PRD](./partitioned-memory-prd.md) |
+
+## 1. 背景
+
+智能心跳已经可以生成摘要、后续任务和记忆候选，但这还不是完整学习：
+
+- 候选是否改善未来行为没有评估。
+- 一条反思是否会被检索和使用并不确定。
+- 没有 Baseline、回放集、Shadow、晋升和回滚。
+- 没有持续监控候选生效后的收益与退化。
+- 如果允许系统直接修改 Prompt、Skill 或规则，可能发生静默劣化。
+
+持续学习必须建立为可观察、可评估、可批准、可回滚的闭环，而不是“让模型自动改自己”。
+
+## 2. 产品定义
+
+```text
+Observe
+  → Propose candidate
+  → Validate structure and safety
+  → Evaluate against baseline
+  → Shadow
+  → Promote with approval
+  → Monitor
+  → Keep, revise, rollback or archive
+```
+
+学习产物只有在改变未来行为后才算生效；只保存一条 Reflection 仍属于记忆候选。
+
+## 3. 已确认的产品决策
+
+1. 评估门必须先于任何自动应用能力上线。
+2. 新候选默认 `candidate`，通过离线评估后先进入 `shadow`。
+3. 第一阶段只允许人工晋升。
+4. 每次晋升必须记录 Baseline、候选、评估结果、作用域和回滚版本。
+5. 学习不能修改安全边界、工具审批、目录权限、沙箱或 Electron 配置。
+6. 失败案例和用户负反馈只作为评估数据，不直接成为新规则。
+7. 回放案例必须脱敏、版本化，并得到用户明确选择或来自仓库公开样例。
+8. 模型评估不是唯一真值，优先使用确定性验收和人工反馈。
+9. 生效后的候选继续监控，发生退化可自动停用，但不能自动换上另一个候选。
+10. 没有足够证据时保持 `inconclusive`，不强行晋升。
+
+## 4. 学习产物
+
+首期只支持：
+
+| 产物 | 作用 | 是否可自动应用 |
+| --- | --- | --- |
+| Memory | 改善相关上下文召回 | 否，人工确认 |
+| Automation Template | 改善目标、步骤、提示或预算默认值 | 否，创建新草稿 |
+| Prompt Variant | 用于实验比较 | 否 |
+| Rubric | 改善评估标准 | 否 |
+| Retrieval Preference | 调整特定 Automation 的检索配置候选 | 否 |
+
+后续评估：
+
+| 产物 | 风险 |
+| --- | --- |
+| Skill | 可能扩大行为和工具使用 |
+| Procedure | 可能长期影响多个任务 |
+| Non-security Rule | 可能阻断或改变行为 |
+| Agent Preference | 可能产生难以解释的个性漂移 |
+
+永久禁止自动学习修改：
+
+- 工具权限和审批策略。
+- 工作区根目录和文件访问范围。
+- 网络、远程消息和电脑控制权限。
+- Electron 安全设置。
+- API Key、凭据和 Provider Endpoint。
+- 删除、支付、发布和生产操作政策。
+
+## 5. 候选来源
+
+- 用户对回答、任务或 Supervisor 意见的显式反馈。
+- 智能心跳提出的重复模式。
+- 自动化 Run 的成功与失败比较。
+- 并行实验结论。
+- 回放评估发现的稳定差异。
+- 用户手动创建。
+
+候选必须包含：
+
+- 作用域。
+- 产物类型。
+- 来源证据。
+- 预期改善的指标。
+- 可能影响的行为。
+- 风险级别。
+- Baseline 引用。
+- 建议的评估集。
+
+模型不能仅凭一条成功案例宣称“已学习”。
+
+## 6. 状态机
+
+```text
+candidate
+  → evaluating
+  → rejected
+  → inconclusive
+  → shadow
+  → awaiting_approval
+  → promoted
+  → paused
+  → rolled_back
+  → archived
+```
+
+| 状态 | 含义 |
+| --- | --- |
+| `candidate` | 尚未评估 |
+| `evaluating` | 正在运行离线评估 |
+| `rejected` | 明确退化、安全不合格或无效 |
+| `inconclusive` | 证据不足 |
+| `shadow` | 计算候选决策但不影响真实行为 |
+| `awaiting_approval` | 达到晋升标准，等待用户 |
+| `promoted` | 已作为指定作用域的当前版本 |
+| `paused` | 暂停影响，保留版本 |
+| `rolled_back` | 已恢复前一版本 |
+| `archived` | 不再评估和使用 |
+
+## 7. 评估案例
+
+### 7.1 案例来源
+
+优先级：
+
+1. 仓库内公开、无隐私的固定评测样例。
+2. 用户手动创建的案例和期望。
+3. 用户明确选择并脱敏的历史会话或任务。
+4. 实验中产生、经用户批准保留的案例。
+
+禁止默认采样所有私人会话用于学习。
+
+### 7.2 案例结构
+
+```ts
+type EvaluationCase = {
+  id: string
+  suiteId: string
+  input: EvaluationInput
+  assertions: EvaluationAssertion[]
+  forbiddenBehaviors: EvaluationAssertion[]
+  source: EvaluationCaseSource
+  sensitivity: 'public' | 'private_local'
+  version: number
+}
+```
+
+断言可以是：
+
+- 输出符合 Schema。
+- 包含或不包含确定文本模式。
+- 引用来自允许知识库。
+- 不调用工具。
+- 任务状态和成果存在。
+- 测试命令通过。
+- 人工评分。
+- 模型 Rubric 分项。
+
+### 7.3 冻结
+
+一次评估冻结：
+
+- 案例版本。
+- Baseline 版本。
+- Candidate 版本。
+- Runtime 和模型。
+- 知识、记忆和工作区快照。
+- 预算。
+- 评估器版本。
+
+设置变化不改变已开始的评估。
+
+## 8. 评估门
+
+### 8.1 判定
+
+```ts
+type GateVerdict = {
+  decision: 'reject' | 'inconclusive' | 'shadow'
+  baselineMetrics: MetricValue[]
+  candidateMetrics: MetricValue[]
+  regressions: Regression[]
+  caseIds: string[]
+  evaluatorVersions: string[]
+  notes: string
+}
+```
+
+最小规则：
+
+1. 任何安全、权限或硬约束退化立即 Reject。
+2. 确定性质量指标不能低于配置阈值。
+3. 成本和延迟退化必须在允许范围。
+4. 开放质量指标至少非退化，或收益足以覆盖明确成本。
+5. 案例数或评估器不足时 Inconclusive。
+6. 通过离线门只进入 Shadow，不直接 Promote。
+
+### 8.2 Baseline
+
+Baseline 是当前已生效版本或明确的无候选行为。不能用另一个同时变化的实验配置充当 Baseline。
+
+### 8.3 多模型评估
+
+模型 Rubric 可使用与被评候选不同的模型，但必须：
+
+- 固定版本和提示。
+- 隐藏候选身份。
+- 随机化顺序。
+- 保存分项和证据。
+- 在关键晋升中结合确定性或人工评估。
+
+## 9. Shadow
+
+Shadow 模式：
+
+- 接收与当前真实行为相同的有界输入。
+- 计算候选会做出的选择或输出。
+- 不调用有副作用工具。
+- 不替换用户看到的结果。
+- 不写入长期记忆。
+- 保存与实际结果可比较的指标。
+
+对于成本较高的候选：
+
+- 只对抽样的已授权案例运行。
+- 用户可设置月度调用上限。
+- 系统繁忙时延后。
+
+Shadow 达到配置的最小观察数且无安全退化后进入 `awaiting_approval`。
+
+## 10. 晋升
+
+晋升对话框必须显示：
+
+- 候选将改变什么。
+- 作用域和受影响计划。
+- 来源。
+- Baseline 与 Candidate 指标。
+- 失败案例和不确定性。
+- 额外成本。
+- 回滚版本。
+
+用户可以：
+
+- 晋升。
+- 继续 Shadow。
+- 拒绝。
+- 缩小作用域后重新评估。
+
+晋升采用原子版本切换。不能在一半对象上成功、一半失败。
+
+## 11. 上线后监控
+
+监控：
+
+- 使用次数。
+- 成功、失败和无结论。
+- 确定性指标。
+- 用户采纳、撤销和负反馈。
+- Token、耗时和工具调用变化。
+- Supervisor 警告变化。
+
+自动暂停条件：
+
+- 安全或权限硬约束失败。
+- 确定性错误率超过阈值。
+- 连续崩溃或格式失败。
+- 成本超过批准上限。
+
+自动暂停只恢复到上一已批准版本，并通知用户。系统不能自行选择新候选替代。
+
+## 12. 回滚
+
+- 每个 Promoted 产物有不可变版本。
+- 保存前一版本和作用域绑定。
+- 一键回滚使用原子切换。
+- 回滚不删除失败版本，保留指标和原因。
+- 当前有运行使用该版本时，只影响下一次 Run；紧急安全暂停可取消尚未开始的 Run。
+- 被回滚候选再次晋升必须重新评估。
+
+## 13. 衰减与归档
+
+- 长期未使用的候选和 Shadow 可归档。
+- Promoted 产物不因时间静默删除。
+- Memory 类型遵守分区记忆的衰减规则。
+- 评估案例变化后，相关候选标记为“评估过期”。
+- 模型或 Runtime 大版本变化时，可要求重新回放。
+- 归档保留不含私人正文的指标和版本元数据。
+
+## 14. 信息架构
+
+建议在自动化中心增加“学习”：
+
+1. **候选**：来源、作用域、预期收益和风险。
+2. **评估中**：进度、案例和预算。
+3. **Shadow**：观察数、差异和成本。
+4. **待批准**：晋升摘要。
+5. **已生效**：当前版本、使用量和健康状态。
+6. **历史**：拒绝、回滚和归档。
+
+候选详情页签：
+
+- 概览。
+- 变更 Diff。
+- 评估案例。
+- 指标和失败。
+- Shadow。
+- 版本与回滚。
+
+## 15. 数据模型建议
+
+```ts
+type LearningArtifact = {
+  id: string
+  scopeKind: 'global' | 'project' | 'automation' | 'agent'
+  scopeId?: string
+  kind:
+    | 'memory'

+  payload: JsonValue
+  sourceRefs: LearningSourceRef[]
+  baselineVersionId?: string
+  promotedVersionId?: string
+  createdAt: string

+- `evaluation_suites`
+- `evaluation_cases`
+- `evaluation_runs`
+- `evaluation_results`
+- `shadow_observations`
+- `promotion_events`
+- `rollback_events`
+
+## 16. 安全与隐私
+
+1. Apply 层拒绝没有 Gate Verdict 的候选。
+2. 产物类型和目标作用域使用代码白名单。
+3. 安全与权限配置不在可学习目标白名单中。
+4. 私人评估案例只在本地使用，不导出或发送到未授权 Provider。
+5. Shadow 不调用有副作用工具。
+6. Candidate 内容和评估输出都视为不可信数据。
+7. Renderer 不能直接设置 Promoted 状态，Main 验证评估与审批。
+8. 删除私人评估案例后清理派生缓存和 Embedding。
+9. 日志不记录完整案例、Prompt、回答、文件或凭据。
+10. 自动暂停采用确定性条件，不依赖模型自由判断。
+
+## 17. 实施顺序
+
+严格顺序：
+
+1. 建立版本化评估案例和确定性断言。
+2. 复用并行实验运行 Baseline 与 Candidate。
+3. 实现 Gate Verdict，只有 Reject、Inconclusive 和 Shadow。
+4. 实现 Shadow，但不允许 Apply。
+5. 实现人工晋升和原子回滚。
+6. 实现上线监控和确定性自动暂停。
+7. 首先开放 Memory 和 Automation Template。
+8. 经过长期验证后再评估 Skill、Procedure 和非安全规则。
+
+不能先做自动改 Prompt，再补评估门。
+
+## 18. 验收标准
+
+- [ ] 没有评估结果的候选无法晋升。
+- [ ] 安全、权限或硬约束退化必定 Reject。
+- [ ] 评估不足时显示 Inconclusive，不强行选优。
+- [ ] Baseline、Candidate、案例、Runtime 和评估器都被冻结和版本化。
+- [ ] Shadow 不影响用户结果、不调用副作用工具、不写长期记忆。
+- [ ] 晋升前展示收益、退化、成本、作用域和回滚版本。
+- [ ] 第一阶段只有用户可以批准晋升。
+- [ ] 晋升和回滚采用原子版本切换。
+- [ ] 生效后出现确定性严重退化时自动暂停并恢复上一批准版本。
+- [ ] 系统不会自动选择另一个候选替代。
+- [ ] 私人会话不会默认进入评估集。
+- [ ] 安全策略、权限、目录、凭据和 Electron 配置不属于可学习产物。

+
+## 文档信息
+
+| 项目 | 内容 |
+| --- | --- |
+| 状态 | 设计中 |
+| 版本 | 0.1 |
+| 日期 | 2026-08-13 |
+| 依赖 | [自动化平台总体设计](./automation-platform-architecture.md) |
+| 体验参考 | GoodBuddy 魔法笔记 AI 评论流 |
+
+## 1. 背景
+
+GoodBuddy 的魔法笔记已经提供一种有价值的交互：用户持续写作，AI 在右侧以长评、建议和
+警告进行评论，用户可以选择综合、扩展、润色、质疑或发散方向。该能力是内容分析，不是
+会话监督：
+
+- 只分析当前笔记或待办文本。
+- 不观察聊天任务、工具调用、目标、预算或成果。
+- 不参与任务状态机。
+- 不引用具体会话步骤。
+- 不支持关注、暂停和解决流程。
+
+随着目标任务和并行实验出现，用户需要一个与执行 Agent 相互独立的观察者，帮助发现偏题、
+遗漏、矛盾、证据不足、循环、成本失控和潜在风险。
+
+## 2. 产品定义
+
+会话监督是在明确范围和策略下，对 Conversation、Task、AutomationRun 或 ExperimentRun
+的可见事件进行独立观察，产生带证据的评论、告警和人工介入请求。
+
+它不是：
+
+- 第二个替用户发言的聊天 Agent。
+- 隐藏推理查看器。
+- 工具审批器。
+- 可以绕过安全边界的“总管理员”。
+- 自动修正执行过程的通用控制器。
+
+## 3. 核心产品判断
+
+建议增加会话监督，首期采用“魔法笔记式右侧评论流”，但只开放以下能力：
+
+```text
+观察
+→ 评论 / 警告
+→ 用户查看证据
+→ 用户忽略、采纳、询问、暂停或调整任务
+```
+
+首期模型监督不自动暂停。只有现有确定性安全规则、预算和用户显式配置的硬门禁可以自动暂停。
+
+## 4. 已确认的产品决策
+
+1. 监督默认关闭，由用户对会话、任务、自动化或实验显式启用。
+2. 监督只读取用户可查看的消息、工具事件、状态、指标、成果摘要和目标。
+3. 不读取、推断或保存模型隐藏推理链。
+4. 每条重要判断必须引用具体消息、工具、步骤、指标或成果。
+5. 模型监督默认只评论、警告或请求人工复核。
+6. 确定性监督负责权限、预算、Schema、幂等和硬停止条件。
+7. 监督器不能自动批准工具、扩大范围、修改安全策略或替用户发送消息。
+8. 监督评论不是长期事实，默认不进入记忆。
+9. 监督调用使用独立预算和低于前台对话的优先级。
+10. 同一个事件不能同时产生重复页内警告、评论和全局通知。
+
+## 5. 目标
+
+### 5.1 用户目标
+
+- 在重要会话旁获得不中断主对话的独立评论。
+- 及时发现目标偏移、缺少证据、相互矛盾、重复循环和遗漏要求。
+- 点击监督意见查看对应证据，而不是接受无来源判断。
+- 对监督意见进行采纳、忽略、标记误报或追问。
+- 对自动任务设置更严格的监督策略和人工检查点。
+
+### 5.2 产品目标
+
+- 为普通会话、目标任务和实验提供统一监督契约。
+- 让确定性安全门禁与模型质量判断保持分层。
+- 保存有界、可审计的监督事件，而非复制完整会话。
+- 将用户反馈用于调整规则和评估监督器，但不自动训练或改策略。
+
+## 6. 非目标
+
+- 不展示内部 Chain of Thought。
+- 不持续监控其他应用、键盘、麦克风或屏幕。
+- 不把 Supervisor 设为拥有所有工具的超级 Agent。
+- 不自动修改用户消息或助手回答。
+- 不保证识别所有事实错误、偏见或安全风险。
+- 不把一次模型警告作为任务失败的确定性依据。
+- 不在首期支持 Supervisor 与执行 Agent 自主多轮辩论。
+- 不让 Supervisor 读取未授权项目、会话、知识库或记忆。
+
+## 7. 监督对象
+
+| 对象 | 观察内容 | 典型用途 |
+| --- | --- | --- |
+| 普通会话 | 用户消息、助手回答、引用、工具事件 | 质量和证据评论 |
+| 任务 | 目标、步骤、状态、工具、成果 | 偏离、循环和失败分析 |
+| 自动化 Run | 触发、协议、预算、审批、指标 | 无人值守关注 |
+| 实验 Run | 协议、变量、指标、证据 | 协议一致性 |
+| 实验整体 | 各 Run 结算和比较 | 评估公平性与无结论提示 |
+
+每个监督会话只能绑定一个主对象，并继承其项目范围。
+
+## 8. 监督模式
+
+### 8.1 评论方向
+
+借鉴魔法笔记，普通会话支持：
+
+| 模式 | 行为 |
+| --- | --- |
+| 综合 | 平衡总结目标、进展、风险和下一步 |
+| 质疑 | 检查逻辑跳跃、前提、反例和证据 |
+| 证据 | 检查重要结论是否有可追溯依据 |
+| 目标 | 检查是否回应用户目标和约束 |
+| 风险 | 检查权限、隐私、外部影响和不可逆行为 |
+
+自动化和实验可组合多个检查维度，不用方向单选替代确定性规则。
+
+### 8.2 触发方式
+
+| 方式 | 说明 |
+| --- | --- |
+| 手动 | 用户点击“检查当前会话” |
+| 每次回复后 | 助手一轮完成后异步分析 |
+| 每 N 步 | 自动化或实验按有界步骤间隔分析 |
+| 关键事件 | 工具失败、预算 80%、等待审批、指标异常 |
+| Run 结束 | 进行最终监督回顾 |
+
+首期优先手动和每次回复后。草稿输入不发送给监督器，除非未来明确增加类似魔法笔记的
+草稿评论模式。
+
+### 8.3 干预级别
+
+```ts
+type SupervisorAction =
+  | 'continue'
+  | 'comment'
+  | 'warn'
+  | 'request_review'
+  | 'pause'
+  | 'stop'
+```
+
+- 模型 Supervisor 首期只可产生前四种。
+- `pause` 和 `stop` 只来自确定性门禁或用户操作。
+- 后续若允许模型建议暂停，仍需确定性策略把建议转换为 `request_review` 或经过用户预授权。
+
+## 9. 观察输入
+
+### 9.1 可见输入
+
+- 当前对象的名称、目标和约束。
+- 最近有界消息。
+- 工具名称、状态、参数摘要和输出摘要。
+- 任务和子任务状态。
+- 成果标题、类型、大小和有界摘要。
+- 引用和知识检索诊断。
+- 预算使用。
+- 明确配置的监督规则。
+- 已解决或被忽略的近期监督意见摘要。
+
+### 9.2 禁止输入
+
+- API Key、Token、Cookie 和认证头。
+- 模型隐藏推理。
+- 未授权文件和完整私人文档。
+- 其他项目、会话或实验 Run 的数据。
+- 原始无限长度工具输出。
+- 已删除或用户要求忘记的记忆。
+
+### 9.3 上下文窗口
+
+- 普通会话默认最近 12 条消息和最多 24,000 字符。
+- 任务按最近 20 个关键事件和当前目标组装。
+- 长会话先使用确定性提取，再由监督器处理有界输入。
+- 不能把 Supervisor 自己的旧评论无限回填，最多保留近期未解决摘要。
+
+## 10. 监督输出
+
+```ts
+type SupervisorDecision = {
+  action:
+    | 'continue'
+    | 'comment'
+    | 'warn'
+    | 'request_review'
+  category:
+    | 'goal_drift'
+    | 'missing_requirement'
+    | 'evidence_gap'
+    | 'contradiction'
+    | 'repetition'
+    | 'quality'
+    | 'risk'
+    | 'budget'
+  severity: 'info' | 'low' | 'medium' | 'high'
+  title: string
+  content: string
+  evidence: SupervisorEvidenceRef[]
+  confidence: number
+  suggestedActions: SupervisorSuggestedAction[]
+}
+```
+
+证据引用可以指向：
+
+- `messageId`
+- `toolCallId`
+- `taskEventId`
+- `artifactId`
+- `metricId`
+- `approvalId`
+
+没有有效证据时，严重度最多为 `low`，且必须显示“推测”。
+
+## 11. 确定性监督
+
+以下检查由代码执行：
+
+- Ask 出现写工具请求。
+- 工具或路径超出计划快照。
+- 未经批准的跨项目或跨分区读取。
+- Token、时间、工具、子任务和成果预算。
+- 幂等键冲突或结果未知。
+- 输出 Schema 不匹配。
+- 实验 Run 读取其他 Run 数据。
+- 硬停止条件和必填成果。
+
+确定性监督可以阻止、暂停或终止运行。结果必须包含规则 ID、实际值、阈值和触发事件，
+不通过模型重新解释才能生效。
+
+## 12. 模型监督
+
+适合判断：
+
+- 回答是否偏离用户问题。
+- 计划是否遗漏明确要求。
+- 重要结论是否缺少证据。
+- 当前回答与前文是否矛盾。
+- 是否重复尝试而没有进展。
+- 是否存在值得用户注意的模糊风险。
+
+模型监督输出严格经过 Schema 校验。格式错误最多修复一次；失败不阻塞普通前台会话，
+但在配置为自动化门禁时必须明确记录“监督不可用”，不能假装检查通过。
+
+## 13. 用户交互
+
+### 13.1 右侧评论流
+
+复用魔法笔记的体验方向：
+
+- 长评卡。
+- 建议卡。
+- 警告卡。
+- 证据链接。
+- 评论方向和时间。
+
+每条意见操作：
+
+- 查看证据。
+- 采纳建议。
+- 追问。
+- 忽略。
+- 标记误报。
+- 对自动化请求暂停。
+
+“采纳”只是把建议带入输入框、计划草稿或任务操作，不让 Supervisor 直接执行。
+
+### 13.2 会话输入区
+
+提供监督状态入口：
+
+```text
+监督：关闭 / 综合 / 质疑 / 证据 / 目标 / 风险
+```
+
+这是持久二元启用加方向选择：
+
+- 是否启用使用共享 Switch，`role="switch"`。
+- 方向使用 `SegmentedControl` 或上下文单选菜单。
+- 不把开关和方向做成一组含义不清的页签。
+
+### 13.3 关注状态
+
+会话或任务列表显示未解决意见数量和最高严重度，不能只用颜色。
+只有 `request_review`、高风险警告或确定性暂停触发全局通知。
+
+## 14. 解决流程
+
+```text
+open
+  → acknowledged
+  → resolved
+  → dismissed
+  → false_positive
+```
+
+- `acknowledged`：用户已查看，尚未解决。
+- `resolved`：用户或后续运行说明已处理。
+- `dismissed`：不采纳，但不一定是误报。
+- `false_positive`：明确标记判断不正确。
+
+后续监督输入可以包含未解决意见摘要，已解决意见默认不重复提醒。
+
+## 15. 与任务控制的关系
+
+Supervisor 建议“暂停”时：
+
+1. 创建 `request_review`。
+2. 在任务和会话界面显示原因和证据。
+3. 用户选择继续、暂停、调整目标或取消。
+4. 用户操作进入任务审计。
+
+确定性门禁暂停时：
+
+1. Run 进入 `paused` 或 `waiting_approval`。
+2. 显示规则、阈值和实际值。
+3. 只有满足规则或用户完成对应审批后才能恢复。
+4. 模型评论不能覆盖门禁。
+
+## 16. 与记忆的关系
+
+- 监督评论默认保存在监督记录，不属于长期记忆。
+- 用户采纳后可以手动创建记忆候选。
+- “事实错误”“用户偏好”等监督判断不能自动写入 Project 或 Global。
+- 多次被用户标记误报的模式进入监督评估数据，不直接改变 Prompt。
+- 监督器可以读取绑定范围内的已确认记忆，但必须在证据中标明记忆来源。
+
+## 17. 数据模型建议
+
+```ts
+type SupervisorSession = {
+  id: string
+  projectId?: string
+  targetType: 'conversation' | 'task' | 'automation_run' | 'experiment'
+  targetId: string
+  enabled: boolean
+  mode: 'general' | 'challenge' | 'evidence' | 'goal' | 'risk'
+  triggerPolicy: SupervisorTriggerPolicy
+  budget: SupervisorBudget
+}
+
+type SupervisorRecord = {
+  id: string
+  sessionId: string
+  source: 'deterministic' | 'model'
+  decision: SupervisorDecision
+  status:
+    | 'open'
+    | 'acknowledged'
+    | 'resolved'
+    | 'dismissed'
+    | 'false_positive'
+  createdAt: string
+  resolvedAt?: string
+}
+```
+
+证据关系建议独立表或有界结构化 JSON，并在读取时重新验证对象归属。
+
+## 18. 安全与隐私
+
+1. Supervisor 使用独立可信系统指令，所有观察输入视为不可信数据。
+2. 默认不给 Supervisor 任何工具。
+3. 即使后续提供只读证据工具，也只能读取绑定对象和明确范围。
+4. Supervisor 不接收 Runtime 授权回调，不能请求工具批准。
+5. 普通会话监督失败不影响主回答；自动化配置的强制监督失败进入明确关注状态。
+6. 评论和通知不包含完整私人消息，证据点击后才在原对象中查看。
+7. Renderer 传入的 Evidence ID 必须由 Main 重新验证归属。
+8. 删除会话时按产品数据保留策略删除或匿名化监督记录。
+9. 用户关闭监督后停止新分析，但保留历史，除非用户明确删除。
+
+## 19. 性能与预算
+
+- Supervisor 使用独立后台并发池，默认全局并发 1。
+- 前台回复完成后异步运行，不延迟主回答呈现。
+- 同一会话同时只运行一次监督分析，新事件合并为下一次分析。
+- 普通会话每 30 秒最多自动分析一次。
+- 自动化按步骤或关键事件节流。
+- 达到 Supervisor 预算时显示“监督已暂停”，不继续产生费用。
+
+## 20. 实施顺序
+
+1. 定义监督会话、记录、证据和解决状态。
+2. 上线普通会话手动检查和右侧评论流。
+3. 增加每次回复后异步监督、节流和预算。
+4. 接入任务和自动化的确定性观察。
+5. 增加目标、证据和无进展模型检查。
+6. 接入实验协议一致性监督。
+7. 建立误报和有用性评估，不自动改 Prompt。
+
+## 21. 验收标准
+
+- [ ] 监督默认关闭，用户可对单个会话显式启用。
+- [ ] Supervisor 只读取当前对象的有界可见事件。
+- [ ] 隐藏推理、密钥和未授权内容不进入监督输入。
+- [ ] 每条中高严重度意见都有可点击证据。
+- [ ] 无证据推测不会显示为高严重度事实。
+- [ ] 模型监督不能自动暂停、终止、批准工具或替用户发言。
+- [ ] 确定性门禁不依赖模型判断即可阻止越权和超预算行为。
+- [ ] 主会话回答不等待后台 Supervisor 完成。
+- [ ] 用户可采纳、忽略、标记误报和解决意见。
+- [ ] 监督评论默认不进入长期记忆。
+- [ ] 自动化强制监督不可用时明确请求关注，不假装检查通过。
+- [ ] Supervisor 预算耗尽后停止新调用并显示状态。

+# 并行实验工作台 PRD
+
+## 文档信息
+
+| 项目 | 内容 |
+| --- | --- |
+| 状态 | 设计中 |
+| 版本 | 0.1 |
+| 日期 | 2026-08-13 |
+| 依赖 | [自动化平台总体设计](./automation-platform-architecture.md)、[自动任务与目标 PRD](./automation-goals-and-scheduling-prd.md) |
+
+## 1. 背景
+
+GoodBuddy 已能把一个请求并行委派给最多三个只读专家，再综合结果。这适合“一次请求，
+多种专业视角”，但不等同于实验：当前没有结构化变量、重复运行、统一指标、结果晋升和
+Run 级记忆隔离。
+
+本功能借鉴 MesaLogo ParallelLab 中变量隔离、批量 Run、失败结算、指标比较和运行证据
+的思想，但不引入其 Action Space、服务端队列或重型仿真平台。
+
+## 2. 产品定义
+
+并行实验是在冻结的研究问题和执行协议下，生成多个相互隔离的候选 Run，以相同评估标准
+比较结果，并将结论追溯到运行证据。
+
+```text
+Experiment
+  ├─ Question / Hypothesis
+  ├─ Protocol
+  ├─ Variables and Variants
+  ├─ Objectives and Evaluators
+  ├─ Budget and Stop Conditions
+  └─ ExperimentRun × N
+       ├─ Isolated Conversation
+       ├─ Isolated Run Memory
+       ├─ Tasks and Artifacts
+       ├─ Metrics
+       └─ Evidence
+```
+
+## 3. 已确认的产品决策
+
+1. 实验 Run 复用现有 Task、Runtime、Artifact 和审批机制。
+2. 每个 Run 有独立变量、会话、运行记忆、任务和成果。
+3. 默认实验是只读 Ask；写工作区的实验后续使用每 Run 独立沙箱。
+4. 多个 Run 不能并发修改同一个用户工作区。
+5. 失败、取消、预算耗尽或结果不完整的 Run 不参与最佳结果选择。
+6. 没有成功 Run 时实验为失败或无结论，不能报告成功。
+7. 模型生成的实验协议必须可审查、编辑和版本化。
+8. 评估优先使用确定性指标；模型 Rubric 显示评估器版本和不确定性。
+9. “最佳”只针对声明的目标和约束，不代表普遍最好。
+10. 最佳结果只能创建候选，不能直接覆盖计划、记忆或工作区。
+
+## 4. 目标
+
+- 把问题转为可审查的实验问题、变量、候选和指标。
+- 比较不同提示、模型、专家组合、参数或方案。
+- 监控每个 Run 的状态、成本、证据和失败原因。
+- 查看结果表、差异、稳定性和评估依据。
+- 从候选创建普通任务、计划草稿或记忆候选。
+- 为持续学习提供回放和非退化评估基础。
+
+## 5. 非目标
+
+- 第一阶段不模拟数千 Agent 或社会群体涌现。
+- 不实现任意连续参数的自动贝叶斯优化。
+- 不在样本不足时宣称统计显著性。
+- 不把模型的自报置信度直接作为跨模型比较指标。
+- 不允许实验自行增加样本数、预算或能力范围。
+- 不允许自动部署结果或修改安全策略。
+- 不把专家团队的一次回答自动包装成科学实验。
+
+## 6. 实验类型
+
+| 类型 | 变量示例 | 用途 |
+| --- | --- | --- |
+| Prompt 对比 | 系统说明、输出格式、示例 | 比较自动化协议 |
+| 模型对比 | 已配置文本模型 | 质量、速度和 Token 权衡 |
+| 专家组合 | 专家集合、综合策略 | 多视角研究 |
+| 参数扫描 | 检索模式、Top K、轮数 | 寻找有限参数组合 |
+| 方案候选 | 多个用户或模型方案 | 按统一 Rubric 比较 |
+| 回放评估 | 历史脱敏案例集合 | 验证学习候选是否退化 |
+
+后续多轮情景模拟需要单独定义角色、环境和状态变量。
+
+## 7. 创建流程
+
+### 7.1 研究问题
+
+用户填写：
+
+- 实验名称。
+- 问题和可选假设。
+- 探索、比较、优化或回放验证类型。
+- 项目范围。
+- 期望输出。
+- 禁止行为。
+
+### 7.2 协议
+
+`ExperimentProtocol` 包含：
+
+- 基准输入或案例集。
+- 固定提示和步骤。
+- 变量与候选。
+- Runtime、模型和专家。
+- 工具、知识库和记忆范围。
+- 工作模式。
+- 每 Run 预算。
+- 指标、评估器和停止条件。
+- 重复次数。
+
+模型生成协议草稿时必须标明用户字段、模型建议、确定性指标和模型判断指标。
+
+### 7.3 变量
+
+```ts
+type ExperimentVariable =
+  | { name: string; type: 'enum'; values: JsonValue[] }
+  | {
+      name: string
+      type: 'range'
+      start: number
+      end: number
+      step: number
+    }
+  | { name: string; type: 'boolean' }
+  | { name: string; type: 'prompt_variant'; values: string[] }
+  | {
+      name: string
+      type: 'model_profile'
+      profileIds: string[]
+    }
+  | {
+      name: string
+      type: 'expert_set'
+      expertIdSets: string[][]
+    }
+```
+
+第一阶段只支持有限、确定生成的组合。保存前展示组合数、重复后 Run 总数、最大模型调用、
+Token 和耗时范围，以及最大并发。超过上限时要求缩小变量，不静默抽样。
+
+### 7.4 基准与候选
+
+- 至少一个 Variant。
+- 对比实验建议设置 Baseline。
+- Baseline 与 Candidate 使用相同案例和评估器。
+- 评估器不能读取 Variant 标签和模型名称作为质量信号。
+- 模型评分时随机化候选顺序并保存实际顺序。
+
+## 8. Run 隔离
+
+### 8.1 数据隔离
+
+每个 Run 独立拥有：
+
+- `experimentRunId` 和运行会话。
+- 变量快照和临时上下文。
+- Run 记忆分区。
+- 任务、子任务和成果。
+- 指标、证据和 Runtime 会话标识。
+
+禁止：
+
+- Run A 读取 Run B 的消息、临时记忆或中间成果。
+- 多个 Run 共享可变变量对象。
+- Run 候选记忆在实验结算前进入其他 Run。
+- 通过全局列表误取其他项目或实验数据。
+
+### 8.2 工作区隔离
+
+阶段 1 只支持 Ask 和只读工具。阶段 2 的 Execute Run 使用独立临时沙箱或版本化工作树，
+结果以 Patch 或成果展示，用户选择候选后再进入单独应用流程。
+
+### 8.3 记忆隔离
+
+Run 只读取冻结的 Global、Project、Automation 记忆快照和自己的 Run 分区，
+不读取其他 Run 或实验期间新产生的候选记忆。
+
+## 9. 调度与预算
+
+- 默认最大并发 3，与现有子专家调度能力一致。
+- 还需遵守全局后台并发和模型连接并发。
+- 每个 Variant 使用相同的单 Run 预算。
+- 不因候选暂时领先而静默给它更多预算。
+- 提前停止必须来自预先声明的规则。
+- UI 显示运行、排队、成功、失败和取消数量。
+
+停止条件：
+
+```ts
+type ExperimentStopCondition =
+  | { type: 'all_runs_terminal' }
+  | { type: 'successful_run_count'; count: number }
+  | {
+      type: 'metric_threshold'
+      metric: string
+      operator: string
+      value: number
+    }
+  | { type: 'budget' }
+  | { type: 'deadline'; at: string }
+  | { type: 'manual' }
+```
+
+触发停止后不启动新 Run；是否取消正在运行的 Run 必须在条件中明确。保存停止原因，
+未运行 Variant 不参与最终比较。
+
+## 10. 评估与指标
+
+### 10.1 指标类型
+
+| 类型 | 示例 |
+| --- | --- |
+| 确定性结果 | Schema 有效、测试通过、文件存在、检查项完成 |
+| 运行指标 | 耗时、模型调用、Token、工具调用、成果大小 |
+| 检索指标 | 召回、引用覆盖、降级状态 |
+| 人工评分 | 正确性、可用性、偏好 |
+| 模型 Rubric | 结构、完整性、表达、风险 |
+
+### 10.2 模型 Rubric
+
+必须保存 Rubric 版本、评估模型、输入证据摘要、候选展示顺序、分项得分、结构化理由和
+格式修复。它不能覆盖确定性失败，也不能在缺少证据时编造事实正确性判断。
+
+### 10.3 多目标
+
+```ts
+type ExperimentObjective = {
+  metric: string
+  direction: 'maximize' | 'minimize' | 'target'
+  weight?: number
+  target?: number
+  hardConstraint?: boolean
+}
+```
+
+结算先排除非成功和违反硬约束的 Run，再计算其余指标。存在明显权衡时展示 Pareto 候选，
+不强行选唯一最佳。
+
+## 11. 结算规则
+
+Run 成功要求：
+
+- Runtime 正常结束。
+- 必填成果存在。
+- 必填评估器成功。
+- 未违反硬约束。
+- 没有结果未知的副作用。
+
+Experiment 结算：
+
+| 情况 | 状态 |
+| --- | --- |
+| 至少一个成功 Run，所需 Run 已结算 | `completed` |
+| 所有 Run 失败或无有效结果 | `failed` |
+| 提前停止且已有可比较结果 | `stopped_with_results` |
+| 提前停止且无可比较结果 | `cancelled` |
+| 指标冲突或证据不足 | `inconclusive` |
+
+最佳结果展示 Variant、参数、成功和失败数量、重复运行原始值与聚合、目标分项、硬约束、
+证据和限制。只有一个成功 Run 时使用“当前最高分候选”，不使用“稳定最佳”。
+
+## 12. 重复与复现
+
+- 每个 Variant 默认重复 1 次，波动敏感实验建议至少 3 次。
+- 重复 Run 使用相同变量和独立运行会话。
+- Runtime 支持种子时保存种子，否则明确标注不可完全复现。
+- 聚合展示原始值、中位数或均值，并说明计算方式。
+- 样本不足时不展示统计显著性结论。
+
+## 13. 会话监督接入
+
+Supervisor 可以检查偏离协议、遗漏必填输出、证据不足和候选间协议不一致；
+确定性预算或权限违规可以暂停 Run，模型判断默认只警告或请求人工复核。
+
+Supervisor 不能：
+
+- 根据其他候选结果提示当前 Run。
+- 临时修改某个候选协议。
+- 自动提高预算或批准工具。
+
+## 14. 信息架构
+
+实验工作台页签：
+
+1. **设计**：问题、协议、变量、指标和预算。
+2. **运行**：总体进度、Run 表和状态。
+3. **比较**：指标表、图表、差异和 Pareto 候选。
+4. **证据**：按结论、指标和 Run 查看证据。
+5. **结论**：总结、限制和后续操作。
+
+Run 详情展示参数、协议版本、时间线、消息、任务、成果、监督记录、指标、评估理由、
+上下文和记忆快照、Token、耗时与错误。
+
+## 15. 后续操作
+
+允许：
+
+- 用候选参数创建普通任务。
+- 创建自动化计划草稿。
+- 保存实验模板。
+- 创建记忆候选。
+- 追加确认 Run。
+- 导出脱敏结果摘要。
+
+不得自动启用新计划、覆盖现有计划、确认长期记忆、应用工作区 Patch 或扩大权限。
+
+## 16. 数据模型建议
+
+```ts
+type Experiment = {
+  id: string
+  projectId?: string
+  name: string
+  question: string
+  status:
+    | 'draft'
+    | 'queued'
+    | 'running'
+    | 'paused'
+    | 'completed'
+    | 'failed'
+    | 'stopped_with_results'
+    | 'inconclusive'
+    | 'cancelled'
+  protocolVersion: number
+  totalRuns: number
+  successfulRuns: number
+  failedRuns: number
+}
+
+type ExperimentRun = {
+  id: string
+  experimentId: string
+  variantId: string
+  repetition: number
+  automationRunId: string
+  variables: Record<string, JsonValue>
+  status: string
+  goalStatus: 'met' | 'not_met' | 'inconclusive'
+}
+```
+
+建议表：
+
+- `experiments`
+- `experiment_protocol_versions`
+- `experiment_variants`
+- `experiment_runs`
+- `experiment_run_metrics`
+- `experiment_evidence`
+- `experiment_conclusions`
+
+## 17. 安全与隐私
+
+1. 协议、案例、输出和评估输入都视为不可信数据。
+2. Renderer 不能指定其他项目的 Run 或记忆分区。
+3. 每个 Run 使用唯一 Runtime conversation ID，并在结束后释放。
+4. 实验默认不能写用户工作区。
+5. 模型对比不能传递其他供应商的凭据或隐藏配置。
+6. 导出默认不包含完整私人案例、提示、消息或文件内容。
+7. 取消实验传播到排队和运行任务，但不伪装撤销已有副作用。
+8. 实验删除不能误删已由用户独立保存的成果或计划候选。
+
+## 18. 实施顺序
+
+1. 建立 Experiment、Variant、Run 聚合实体和只读 Ask Run。
+2. 实现有限组合、预算估算、并发调度和运行监控。
+3. 增加确定性指标、失败结算和结果比较。
+4. 增加模型 Rubric、人工评分和证据工作台。
+5. 增加重复运行和回放评估。
+6. 最后评估独立工作树中的 Execute 实验。
+
+## 19. 验收标准
+
+- [ ] 保存前显示变量组合、重复后 Run 总数和最大预算。
+- [ ] 每个 Run 的会话、变量、记忆、任务和成果相互隔离。
+- [ ] 默认实验无法写用户工作区。
+- [ ] 最大并发和全局后台预算同时生效。
+- [ ] 各 Variant 使用相同单 Run 预算。
+- [ ] 失败、取消、预算耗尽和不完整 Run 不参与最佳选择。
+- [ ] 全部 Run 失败时实验不报告成功或最佳结果。
+- [ ] 模型 Rubric 显示版本、模型、分项和证据。
+- [ ] 多目标冲突时可以展示多个 Pareto 候选。
+- [ ] 用户可从候选创建草稿，但不会自动部署或确认记忆。
+- [ ] 结论能追溯到具体 Run、指标、成果和证据。

+# 分区记忆 PRD
+
+## 文档信息
+
+| 项目 | 内容 |
+| --- | --- |
+| 状态 | 设计中 |
+| 版本 | 0.1 |
+| 日期 | 2026-08-13 |
+| 依赖 | [自动化平台总体设计](./automation-platform-architecture.md) |
+
+## 1. 背景
+
+GoodBuddy 当前记忆已经支持：
+
+- `global`、`project`、`conversation` 三种作用域。
+- `preference`、`fact`、`summary`、`procedure` 四种类型。
+- `proposed`、`confirmed`、`rejected` 三种状态。
+- 智能心跳提出 Global 或 Project 记忆候选，由用户确认。
+
+但当前能力仍不足以支撑自动化和并行实验：
+
+1. 交互请求会把已加载列表中的最多 20 条已确认记忆直接拼入提示，缺少查询相关度和明确的
+   会话级过滤契约。
+2. 数据库有会话作用域，但心跳只提出 Global 和 Project 记忆。
+3. 缺少 Automation、Experiment 和 Run 分区。
+4. 来源字段存在于表结构，但普通创建和心跳候选尚未完整保存来源关系。
+5. 缺少事实的有效时间、冲突、替代、访问记录和衰减。
+6. 实验 Run 若共享可变记忆，会造成候选互相污染。
+
+本设计先完成分区、来源、检索和生命周期，再评估时间知识图谱。
+
+## 2. 核心产品判断
+
+### 2.1 分区是权限和隔离边界
+
+分区不是搜索标签。每次读取先根据运行快照确定允许分区，再在这些分区中检索。
+模型不能请求任意分区 ID，Renderer 也不能把任意 ID 作为可信范围。
+
+### 2.2 作用域和记忆种类是两个维度
+
+- 作用域回答“谁可以读取”。
+- 类型回答“这是什么信息”。
+
+不能用 `summary` 表示会话范围，也不能用 `project` 表示事实类型。
+
+### 2.3 记忆和知识库分离
+
+| 记忆 | 知识库 |
+| --- | --- |
+| 用户偏好、项目约定、过程经验、会话摘要 | 文档、网页、文件和外部资料 |
+| 小规模、动态、可确认和可遗忘 | 大规模、按来源同步和引用 |
+| 强调作用域、来源、时态和行为影响 | 强调检索、分块和证据引用 |
+
+不能把整个文档或长工具输出保存为记忆。
+
+### 2.4 第一阶段不需要图数据库
+
+SQLite 显式字段、FTS、来源关系和可选本地 Embedding 足以支持首期。时间图谱只有在以下
+需求经过验证后再建设：
+
+- 实体关系的多跳查询。
+- 事实有效期和关系演变。
+- 同一实体跨大量会话的别名消歧。
+- 可解释的关系证据链。
+
+## 3. 目标
+
+- 为会话、自动化和并行 Run 提供严格隔离。
+- 每条记忆显示范围、类型、状态、来源、时间和敏感度。
+- 在允许分区内按相关性、重要性、新鲜度和预算检索。
+- 保留冲突事实和时态，不静默覆盖。
+- 让候选记忆经过确认或评估后再晋升。
+- 支持编辑、移动、合并、拒绝、归档、删除和要求忘记。
+- 记录哪些 Run 实际读取了哪些记忆。
+
+## 4. 非目标
+
+- 不保存完整聊天、文档、工具日志或隐藏推理作为记忆。
+- 不自动确认敏感个人信息。
+- 不默认跨项目共享 Project、Conversation 或 Run 记忆。
+- 不允许模型自行创建新分区或跨分区移动记忆。
+- 不承诺记忆中的事实永远正确。
+- 第一阶段不建设 Memory Palace 五层空间隐喻。
+- 不把向量相似度作为权限判定。
+
+## 5. 分区模型
+
+### 5.1 分区类型
+
+```ts
+type MemoryNamespaceKind =
+  | 'global'
+  | 'project'
+  | 'conversation'
+  | 'automation'
+  | 'experiment'
+  | 'run'
+  | 'agent'
+```
+
+| 分区 | 内容 | 生命周期 |
+| --- | --- | --- |
+| Global | 用户长期偏好和跨项目通用约定 | 长期，严格确认 |
+| Project | 项目术语、目标、决策和流程 | 随项目 |
+| Conversation | 当前会话摘要、局部约定和待澄清信息 | 随会话或短期 |
+| Automation | 某计划的稳定协议经验和运行约定 | 随计划 |
+| Experiment | 实验设计、结论和限制 | 随实验 |
+| Run | 单次运行观察、中间状态和临时经验 | 短期、严格隔离 |
+| Agent | 某专家或角色的个性化经验 | 后续，默认关闭 |
+
+首期实现 Global、Project、Conversation、Automation 和 Run。Experiment 可复用
+Automation 机制后增加；Agent 必须在专家长期身份明确后再开放。
+
+### 5.2 分区标识
+
+```text
+global
+project:{projectId}
+conversation:{conversationId}
+automation:{planId}
+experiment:{experimentId}
+run:{automationRunId}
+agent:{expertId}
+```
+
+数据库使用 UUID 外键和显式 `kind`，上述字符串只用于日志和展示，不作为未经验证的访问凭据。
+
+### 5.3 读取链
+
+交互会话推荐：
+
+```text
+Conversation → Project → Global
+```
+
+自动化 Run：
+
+```text
+Run → Automation → Conversation（可选）→ Project → Global
+```
+
+实验 Run：
+
+```text
+Run → Experiment frozen snapshot → Project frozen snapshot → Global frozen snapshot
+```
+
+各层使用独立结果数和字符预算。Run 层不能覆盖权限更高层，只能提供更具体上下文。
+
+## 6. 记忆条目
+
+```ts
+type MemoryItem = {
+  id: string
+  namespaceId: string
+  kind:
+    | 'preference'
+    | 'fact'
+    | 'summary'
+    | 'procedure'
+    | 'decision'
+    | 'constraint'
+    | 'reflection'
+  content: string
+  status:
+    | 'candidate'
+    | 'confirmed'
+    | 'rejected'
+    | 'superseded'
+    | 'archived'
+  confidence: number
+  salience: number
+  sensitivity: 'normal' | 'sensitive' | 'restricted'
+  validFrom?: string
+  validTo?: string
+  expiresAt?: string
+  sourceId: string
+  supersedesId?: string
+  createdAt: string
+  updatedAt: string
+}
+```
+
+兼容映射：
+
+- 当前 `proposed` 对应 `candidate`。
+- 当前 `confirmed` 和 `rejected` 保留。
+- 当前四种类型保留，并按真实需求增加 `decision`、`constraint` 和 `reflection`。
+
+## 7. 来源与证据
+
+### 7.1 来源类型
+
+```ts
+type MemorySource =
+  | { type: 'user_entry'; createdBy: 'user' }
+  | {
+      type: 'message'
+      conversationId: string
+      messageId: string
+    }
+  | { type: 'task'; taskId: string; eventId?: string }
+  | { type: 'heartbeat'; heartbeatRunId: string; entryId: string }
+  | { type: 'supervisor'; supervisorRecordId: string }
+  | { type: 'automation_run'; automationRunId: string }
+  | {
+      type: 'experiment_conclusion'
+      experimentId: string
+      conclusionId: string
+    }
+  | { type: 'artifact'; artifactId: string }
+```
+
+### 7.2 来源规则
+
+- 每条非用户手动记忆必须有来源。
+- 来源被删除时记忆不一定删除，但显示“来源不可用”并降低可信度。
+- 来源内容不复制进记忆表，只保存有界证据摘要和引用。
+- 用户确认只表示允许后续使用，不表示事实已被外部验证。
+- Supervisor 判断只能生成候选，不能直接生成确认事实。
+
+## 8. 候选生成
+
+候选来源：
+
+- 智能心跳。
+- 用户明确“记住这个”。
+- 会话结束总结。
+- 自动化 Run 结束反思。
+- 实验结论。
+- Supervisor 建议后用户采纳。
+
+候选生成必须：
+
+- 限制数量和长度。
+- 检查同分区近似重复。
+- 标记推断和不确定性。
+- 不自动提取密码、密钥、身份号码、健康和财务等敏感信息。
+- 不把指令型工具输出自动当作用户偏好。
+- 不从助手自己的未确认陈述提取事实。
+
+## 9. 确认与晋升
+
+### 9.1 允许路径
+
+```text
+Run candidate
+  → Automation candidate
+  → Project candidate
+  → Global candidate
+```
+
+每次跨层都是显式晋升，不是移动原记录：
+
+- 保留原候选和来源。
+- 创建目标分区新版本。
+- 保存晋升理由、评估和操作者。
+- 可回滚到晋升前状态。
+
+### 9.2 确认规则
+
+- Global 默认必须人工确认。
+- Project 默认人工确认，可对特定低敏感模板启用批量确认。
+- Conversation 可以由用户“记住”直接确认。
+- Automation 和 Run 由自动化协议决定，但只在自身范围有效。
+- Experiment 结论必须结算成功且显示证据，才可成为 Project 候选。
+
+### 9.3 拒绝
+
+拒绝后：
+
+- 不进入检索。
+- 保存规范化摘要指纹，减少重复建议。
+- 用户可查看和恢复。
+- 不把拒绝内容回填给模型，除非用于“避免重复建议”的有界规则。
+
+## 10. 检索
+
+### 10.1 两步边界
+
+```text
+根据可信运行上下文确定允许分区
+→ 在允许分区中检索和排序
+```
+
+这两步不能颠倒。先全库相似搜索再过滤会增加泄漏和实现风险。
+
+### 10.2 排序
+
+建议综合：
+
+- 文本相关度。
+- 可选向量相关度。
+- Salience。
+- Confidence。
+- 新鲜度和有效时间。
+- 类型匹配。
+- 分区优先级。
+- 最近是否已使用。
+
+只有 `confirmed`、当前有效且敏感度允许的记忆进入普通上下文。
+
+### 10.3 预算
+
+建议默认：
+
+| 层级 | 最大条数 | 最大字符 |
+| --- | --- | --- |
+| Run | 8 | 4,000 |
+| Automation / Experiment | 8 | 4,000 |
+| Conversation | 8 | 4,000 |
+| Project | 10 | 5,000 |
+| Global | 6 | 3,000 |
+
+总预算还受模型上下文组装器限制。不能每层取满后无界拼接。
+
+### 10.4 上下文格式
+
+提供给 Runtime 的每条记忆包含：
+
+- 类型。
+- 范围。
+- 内容。
+- 有效时间。
+- 来源类型和可选引用。
+- 不确定或冲突标记。
+
+可信指令明确说明记忆是用户确认的信息或候选证据，不是系统指令。
+
+## 11. 冲突与时态
+
+### 11.1 冲突
+
+新条目与现有条目冲突时：
+
+- 不静默覆盖。
+- 创建冲突关系。
+- 向用户展示两个内容、来源、时间和范围。
+- 用户可选择保留两者、设定有效期、替代旧条目或拒绝新条目。
+
+### 11.2 时态
+
+事实和决策支持：
+
+- `validFrom`：何时开始有效。
+- `validTo`：何时不再有效。
+- `observedAt`：何时被系统观察。
+- `createdAt`：何时写入数据库。
+
+例如“项目目标是 8 月发布”变更为“延期到 9 月”时，旧事实保留历史有效期，新事实成为
+当前有效版本。
+
+### 11.3 适用范围冲突
+
+Project 记忆与 Global 偏好冲突时：
+
+- 当前 Project 的更具体约定优先。
+- 上下文中标明这是项目级覆盖。
+- 不修改 Global 原记录。
+
+## 12. 实验隔离
+
+- 实验启动时冻结可读长期记忆快照。
+- 各 Run 拥有独立 Run 分区。
+- Run 期间产生的候选不互相可见。
+- 实验结算后只从成功 Run 和有效证据生成 Experiment 候选。
+- 最佳 Run 的临时经验不会自动晋升。
+- 重跑相同协议可以选择复用原冻结快照或创建新版本，必须明确显示。
+
+## 13. 生命周期与衰减
+
+### 13.1 访问记录
+
+保存有界使用记录：
+
+- 哪个 Run 检索了该记忆。
+- 是否实际进入模型上下文。
+- 是否被用户或评估器认为有用。
+- 最近使用时间和命中次数。
+
+不保存完整请求副本。
+
+### 13.2 衰减
+
+- Preference、Constraint 和 Procedure 不仅因时间自动失效。
+- Conversation、Run Summary 和 Reflection 可配置过期时间。
+- 长期未命中、低 Salience 的候选可归档。
+- 衰减先影响排序，再进入归档，不直接硬删除。
+- Restricted 记忆可采用更短保留期。
+
+### 13.3 删除与忘记
+
+- 删除记忆后立即停止检索。
+- “忘记”同时清理派生索引、Embedding 和缓存。
+- 来源消息是否删除由其自身生命周期决定，不能反向静默删除用户会话。
+- 删除 Project 时清理其分区、自动化和 Run 记忆，不影响 Global。
+- 审计只保留不含原内容的删除事件和 ID 摘要。
+
+## 14. 敏感信息
+
+| 敏感度 | 行为 |
+| --- | --- |
+| Normal | 按普通确认和检索规则 |
+| Sensitive | 必须人工确认，UI 持续标记 |
+| Restricted | 默认不允许模型自动生成；仅用户手动创建，读取需要显式启用 |
+
+禁止自动长期记忆：
+
+- 密码、密钥、Token、Cookie。
+- 完整身份证件、银行卡和账户凭据。
+- 未经用户明确要求的健康、财务和高度私密信息。
+- 工具输出中的认证数据。
+
+## 15. 信息架构
+
+记忆中心建议页签：
+
+1. **记忆**：按范围、类型、状态和敏感度浏览。
+2. **待确认**：候选、冲突和晋升请求。
+3. **分区**：Global、Project、Conversation、Automation、Run 的统计和访问策略。
+4. **使用记录**：哪些 Run 使用了哪些记忆。
+5. **设置**：候选生成、保留期、敏感信息和检索预算。
+
+每条记忆展示内容、类型、范围、来源、状态、时间、置信度、重要性和冲突。
+
+## 16. 数据模型建议
+
+建议表：
+
+- `memory_namespaces`
+- `memory_items`
+- `memory_sources`
+- `memory_relations`
+- `memory_access_events`
+- `memory_promotion_events`
+- `memory_embeddings`，可选
+
+现有 `memory_items` 可渐进迁移：
+
+1. 增加 Namespace 并回填现有 Scope。
+2. 回填来源为空的旧记录为 `legacy_unknown`。
+3. 增加状态和类型兼容映射。
+4. 上线新检索器后再停止旧的列表拼接方式。
+
+## 17. 安全与隐私
+
+1. 分区解析只在 Main 进行。
+2. 所有 ID 重新验证对象归属和项目范围。
+3. Renderer 无法指定任意分区进行搜索。
+4. Runtime 只能获得有界记忆文本和来源摘要。
+5. Embedding 只能发送用户已配置允许的记忆，Restricted 默认不发送外部服务。
+6. 记忆内容和来源不出现在普通日志与通知。
+7. 跨分区晋升需要明确操作和审计。
+8. Ask 和 Execute 使用同一只读记忆检索边界。
+9. 记忆不能绕过系统指令、工具审批和工作区权限。
+
+## 18. 实施顺序
+
+1. 修正当前交互请求的范围过滤，确保只读 Global、当前 Project 和当前 Conversation。
+2. 增加来源记录和“实际进入上下文”的诊断。
+3. 建立 Automation 和 Run Namespace。
+4. 上线有界相关检索，替换简单列表前 20 条拼接。
+5. 增加冲突、时态、替代和归档。
+6. 增加实验冻结快照与 Run 隔离。
+7. 增加可选本地 Embedding 和混合排序。
+8. 只有明确需求后再评估时间知识图谱。
+
+## 19. 验收标准
+
+- [ ] 普通会话只读取 Global、当前 Project 和当前 Conversation 的允许记忆。
+- [ ] 自动化 Run 只读取运行快照绑定的分区。
+- [ ] 实验 Run 不能读取其他 Run 的消息或记忆。
+- [ ] 每条非手动记忆都有可追溯来源。
+- [ ] 候选和被拒绝记忆不进入普通上下文。
+- [ ] Global 和 Project 晋升需要明确确认或评估。
+- [ ] 冲突事实不被静默覆盖。
+- [ ] 当前有效事实可通过有效时间正确选择。
+- [ ] 上下文组装遵守各层和总字符预算。
+- [ ] UI 能显示某次 Run 实际使用的记忆。
+- [ ] 删除或忘记后，文本、索引和缓存不再可检索。
+- [ ] Restricted 记忆不会自动生成或发送给外部 Embedding 服务。
