+
+| 状态 | 优先级 | 编号 | 问题 | 证据 | 当前结论 / 下一步 |
+|---|---:|---|---|---|---|
+| 🔴 | P1 | A1 | MiniApp 的 Capability 请求绕过 Runtime 的 Manifest、Policy 和审计边界 | `tauri/src/runtime/coordination/lineup-runtime.ts:379-381` | 必须由 Runtime 校验 Manifest 声明、Capability Registry/Policy、输入 schema、前台要求和用户确认；不能直接拼接 `app.call` 发出。 |
+| ✅ | P1 | A2 | `bundled` MiniApp 的业务逻辑仍在可信 Host JS 中运行，没有真正的受限执行边界 | `tauri/src/main.ts`、`isolated-surface-host.ts` | 已移除 Host 直接实例化；Task Dashboard/Whiteboard 业务逻辑改在 opaque sandbox iframe 内运行，只能通过 Runtime Bridge 请求能力。待浏览器复验。 |
+| ✅ | P1 | A3 | SDK 暴露完整 workspace，MiniApp 可看到其他 App 实例和全局焦点栈 | `lineup-runtime.ts`、`miniapp-sdk.ts` | 已从 `LineUpMiniAppSDK` 删除 `workspace()`，不再把全局实例和焦点栈交给 bundled MiniApp。 |
+| ✅ | P1 | A4 | 同一个 App 的多个 instance 之间 Inbox 订阅没有隔离 | `lineup-runtime.ts` | 已按 `app_scope + conversation_id + instance_id` 过滤实时订阅，并补充双实例回归测试。 |
+| 🔴 | P1 | A5 | Interact 使用专用 `ChatRuntimeSDK` 旁路，没有和其他 MiniApp 共用 SDK v1 语义 | `tauri/src/core-apps/chat/chat-app-host.ts:67-75`、`main.ts:103-125` | 需要明确并实现统一 SDK 适配：Interact 可有可信 DOM，但交互、Tool、生命周期仍必须通过统一 Runtime 契约；不能让专用接口成为另一套协议。 |
+| 🔴 | P1 | A6 | 标准交互的超时、dismiss、提交和答案 schema 没有由 Runtime 统一裁决 | `lineup-runtime.ts:507-558, 798-815`、`agent-interaction-service.ts:93-101` | 必须让 Interaction 与 Kernel Tool 共用一个终态迁移；超时/dismiss 要写唯一 Agent outbox；提交前按 `notice/choice/confirm/input` 校验答案，拒绝重复和竞态。 |
+| 🔴 | P2 | A7 | 迭代文档中的 Tool 名称和代码 Manifest 不一致 | 主文档 §5.2/§5.3；`reference-miniapps.ts` | 统一契约、Manifest、fixture、Agent Inventory 和验收脚本中的名称。 |
+| 🔴 | P2 | A8 | 当前 Task Dashboard/Whiteboard Surface 主要是 Host 硬编码的静态页面，无法证明真实业务 UI 在各自受限 Surface 内运行 | `main.ts:180-198`、`isolated-surface-host.ts` | 至少提供能代表业务边界的受限 Surface fixture，并验证 MiniApp 业务逻辑不能取得 Host DOM 或 Runtime 内部。 |
+| 🔴 | P2 | A9 | MiniApp progress 没有进入可恢复的 Tool 状态记录 | `miniapp-tool-state.ts` | 如果契约要求进度可恢复，需持久化最后进度并覆盖 Runtime 重启；否则修改文档，明确 progress 只是一种可丢失事件。 |
+| ⚪ | P3 | A10 | App session 记录和 opened/closed 事件没有显式保存 `agent_id` / `conversation_id` 字段 | `app-instance-manager.ts`、`lineup-runtime.ts:203-209,1052-1058` | Envelope 有部分上下文，但应与文档最低字段要求统一，避免未来多 Agent 或跨会话时产生歧义。 |
+| ⚪ | P3 | A11 | 旧的 `openExtensionApp` 公开入口仍提供较宽的旁路能力 | `lineup-runtime.ts:286-300` | 清理旧兼容入口，或明确它只为历史测试保留并加上 instance/call 状态约束。 |
+
+## 1. 已验证通过的部分
+
+- `npm run build` 通过。
+- `npm test -- --run` 通过：29 个测试文件、126 个测试。
+- `git diff --check` 通过。
+- 使用独立 `agent-browser` 会话登录本地测试账号成功。
+- 主 IM 页面、同步状态、应用子会话区域和“启用任务面板”入口可见。
+- 用户消息可以发送并显示“已发送”。
+- AppServer 频道中的其他用户消息已能被 Runtime 安全忽略；真实页面不再出现此前大量的 `scope_mismatch`。
+
+这些证据只能说明基础功能路径可运行，不能证明 MiniApp 隔离、统一 SDK 和所有状态机契约已经满足架构要求。
+
+## 2. P1 问题说明
+
+### A1：Capability 请求没有经过 Runtime 的完整裁决
+
+现在 bundled MiniApp 可以调用 `sdk.capabilities.request(name, reason, input)`，实现直接把参数包装成
+`lineup.v1.app.call`。这意味着 MiniApp 可以请求一个没有写入自己 Manifest、没有经过当前 Capability Policy
+检查、也没有经过 Host 支持检查的能力。即使后续 Agent 还要确认，这条入口也已经让 MiniApp 伪造了系统能力请求。
+
+正确的边界应该是：MiniApp 提出请求 → Runtime 检查 Manifest 和 Policy → 校验参数 → 检查前台/生命周期 →
+进入统一的 Capability 状态机和用户确认流程 → 再由 Host 执行。
+
+### A2：bundled MiniApp 实际仍是可信代码（已修复，待浏览器复验）
+
+已删除 `main.ts` 中对 `TaskDashboardMiniApp` 和 `WhiteboardMiniApp` 的直接实例化。开发版 Surface 现在把
+Task Dashboard/Whiteboard 的业务脚本放进 opaque sandbox iframe，iframe 只能发送经过校验的
+`lineup.miniapp.v1.request`，由 Runtime 执行 Inbox、Tool、生命周期和 Surface 操作；Host 不再把 Runtime 对象、
+Store 或 Transport 注入 MiniApp。
+
+这和架构文档要求的“bundled 也不是 system，必须使用受限 Surface/Bridge”不一致。若继续保留这种实现，必须把
+它们改成明确的 Host 内建 System 代码并修改信任模型；不能继续同时声称它们是普通 bundled MiniApp。
+
+### A3/A4：SDK 数据边界没有做到 instance 级别（已修复）
+
+`LineUpMiniAppSDK` 已不再提供 `workspace()`，因此 MiniApp 不能查看其他 instance 或 Runtime 焦点栈。
+
+`inbox.list()`、ACK 和 `inbox.subscribe()` 现在都按 `app_scope + conversation_id + instance_id` 过滤；新增回归
+测试验证同一 App 的两个 instance 不会互收消息。
+
+### A5：Interact 的 SDK 语义没有统一
+
+Interact 使用 `ChatRuntimeSDK` 和 Host 注入的 `toolInteractions`，而 Task Dashboard/Whiteboard 使用
+`LineUpMiniAppSDK`。可信 DOM 可以是 Interact 与 bundled 的不同实现方式，但交互归属、Tool 状态、Runtime
+动作和错误/恢复语义不能因此分成两套没有共同契约的接口。当前代码无法用一套 SDK golden fixture 证明三类 App
+遵守相同的 Runtime 边界。
+
+### A6：标准交互有两套状态，可能互相打架
+
+- `expireToolCall()` 只修改 Kernel Tool 状态，没有调用 `AgentInteractionService.expire()`，也没有发送 expired outbox。
+- Agent dismiss 修改了 Interaction，但没有同步修改 Kernel Tool 状态。
+- submit 先改 Kernel，再改 Interaction；如果第二步失败，会留下两套状态不一致。
+- 提交结果是任意对象，没有按四种交互类型校验；例如 choice 的 UI 可以提交多选数组，而冻结契约要求的是单选结果。
+
+这会导致 UI、持久化记录和 Agent 看到的最终结果不一致，属于当前迭代必须修复的正确性问题。
+
+## 3. 验收结论
+
+当前结论为（完成本轮 P1-1 后）：
+
+```text
+功能回归：通过
+基础构建与自动化测试：通过
+真实登录和消息发送：通过
+App 架构边界：部分通过（A2 已实现，待浏览器复验；A1/A5/A6 仍不通过）
+MiniApp 隔离与 SDK 规范：A2/A3/A4 已通过，Capability/Interact/状态机仍不通过
+标准交互终态契约：不通过
+迭代整体验收：不通过，先继续处理 A1，再处理 A5/A6；A2～A4 需在最终浏览器复验中确认
+```
+
+本次验收没有修改实现代码。下一步应先处理 P1，再重新运行自动化测试和真实浏览器验收；P2/P3 不能被静默
+删除，至少要在本迭代结束前有明确的修复或延期决定。
