 # 决策记录
 
+## 2026-08-04 工作台 P4/P5 以不可变版本合同驱动正式切片与可信悬停信息
+
+- 背景：P0/P1 已建立不可变可运行版本，P3 已建立一次性 Host/Game Bridge；运行页仍缺少来自正式合同的测试切片控制和不读取 iframe DOM 的游戏内悬停信息。本轮按需求明确跳过 P2，不能借切片或信息面板加入资源替换、参数写入、代码修改或下一版本创建。
+- 决策：`RunnableGameVersion` 在可信 Rust 登记时冻结可选 `testSlices` 与 `resourceDescriptors`，旧版本缺字段按空列表处理且不补造默认切片。正式切片由已通过的 playtest 场景确定，Host 仅通过 `{ sliceId }` 白名单发送 `host.slice.start / host.slice.stop`，前端按有限状态机投影一次性状态；切换、版本 / 项目 / preview / iframe 身份变化立即归零，completed 投影为暂停。
+- 悬停信任边界：游戏只上报 `targetKind=resource|entity|none` 与稳定 `targetId`。宿主只用当前版本 `resourceBindings` 和 `resourceDescriptors` 解析名称、类别 / 格式、尺寸、版本与绑定槽位，游戏自报 label、summary、metrics 不得覆盖可信字段。定位按钮只在资源仍存在于当前 read model 时启用，并在停止当前运行会话后切回资源管理、清除筛选并选中对应资源卡。
+- P2 边界：不实现资源替换、数值参数写入、自然语言新增微调项、代码修改、泥点归因或下一版本；合法游戏消息继续不能触发 Tauri、文件、命令、Agent 或生成副作用。
+- 验证方式：共享 Rust 合同覆盖切片身份 / 顺序 / 初态和未绑定描述拒绝；Tauri 覆盖场景切片冻结、资源描述登记及 bootstrap API；TypeScript 模型 / Bridge 覆盖状态迁移、消息白名单和可信 ID 解析；AppSurface 覆盖首末控制、stop→start、completed 暂停、伪造元数据拒绝与资源定位，并运行 shell typecheck、编码检查和 `git diff --check`。

+- 工作台控制条使用当前版本的正式切片顺序。切换先 stop 后 start；completed 自动暂停；failed、stale、身份漂移或 reload 后控制失效。切片状态属于一次性前端运行会话，不写 manifest。
+- P5 继续禁止宿主读取 iframe DOM。游戏在自身 hit-test / hover 逻辑中仅上报 `targetKind=resource|entity|none` 和稳定 `targetId`；宿主按当前版本 `resourceBindings` 的 resourceId / slotId 解析 `resourceDescriptors`，只展示宿主可信元数据。匹配资源仍存在于当前资源 read model 时，定位按钮先停止并失效当前运行会话，再清除资源筛选、切回资源管理并选中对应资源卡；未命中、离开对象、切片切换和会话失效立即清空。
+- 该阶段不实现 P2：不写数值、不修改代码、不替换资源、不追加资源替换版本，也不允许消息触发 Tauri、文件、命令、Agent 或生成。

 历史命令式 drag preview 句柄与局部连接索引可以保留，但项目工作台不再向资源卡传入该入口。拖动热路径、4096 张真实卡片拖动重渲染和 Chromium p95 门槛统一暂缓；当前回归只要求 Pointer Move 不改变卡片坐标、SVG path 或布局 revision。`ResizeObserver` 仍保持单图层单实例，任何实时 DOM 几何都不得通过 Tauri IPC 往返 Rust。
