+## 2026-09-22 运行页收口：过程提示退出对话区，顶栏统一承载运行入口
+
+- 背景：点播放（以及历史上 `/preview`、`/open-preview`、生成后自动启动预览）都会往对话区写一条 assistant 提示（`运行通过，已载入客户端运行视图：http://127.0.0.1:63155/` 这类）。它常驻对话底部遮挡运行画面，也让对话区混进非对话内容；运行页本身还有三处遮挡与两套皮：预览地址是一行常驻小字（不可点）、版本入口是绝对定位压在画面右上角的浮层、右上角还叠着「生成任务」开关。
+- 决策（对话区只留对话内容）：运行 / 预览的反馈不再进对话区，**成功与失败都**走工作台壳的 toast——`ProjectChatComponentProps.onRunNotice` → `RunNoticeToast`（同一句连续触发重新计时；成功 2.6 秒收起，失败 6 秒收起，`tone` 决定观感）。失败三处：启动预览报错（`运行游戏失败：…`）、缺 Tauri / 缺项目这两条前置条件、以及「在浏览器打开失败」。原先承载这些文案的 `announceProjectChatMessage` 已无调用方，连同删除。
+- 与上一条的关系（2026-09-21「预览激活回接运行入口」）：那条接线决策（先问 Rust 要活体预览、命中就只切视图不重启）原样保留；被本次改掉的只是它当时为这条链路选的**播报渠道**——`经 DirectProjectChatHandle.announce 说一句「已切换到客户端运行视图：<url>」` 按验收反馈（提示常驻对话底部遮挡运行画面）改成 toast，「复用活体预览不重启」的判据与 `tests/previewActivation.test.tsx` 的三条路径不变。
+- 决策（运行页顶栏是唯一入口）：运行区域上方的状态行与预览地址小字整体退役（运行画面回到两行栅格）；预览地址改成顶栏动作区里的一枚「在浏览器打开」按钮（opener 插件的 `openUrl`，只在有活预览时渲染；`scripts/check-native-shells.mjs` 另加「视图里 `openUrl(` 只有一个调用点」的判据）；版本入口搬进同一个顶栏动作区，外观复用 `.game-workbench-view-actions button` 的基础规则，不再自带边框 / 底色 / hover，也不再是绝对定位浮层。版本入口在**资源画布与运行页**显示，UI 编辑器壳里不渲染（那一页是聚焦编辑某个资源的界面）。版本名改用一层 span 承载省略号——按钮是 flex 容器，文本直接挂在按钮上时 `text-overflow` 不生效。
+- 决策（运行页不挂生成任务）：`ResourceCanvasAssetGenerationTasksPanelView` 只在资源画布 / UI 编辑器出现，运行页的入口、面板与锚点都不渲染；`[data-generation-tasks-placement='run']` 那一档坐标与组件 `placement` 联合类型里的 `run` 一并删除。任务不丢，切回资源页即可见。
+- 边界：预览的**启动与切换**仍然只走内置运行画面、不自动开系统浏览器——`scripts/check-native-shells.mjs` 那条负向守卫保持原样，本轮只补「浏览器入口只有顶栏这一枚按钮」的正向断言。
+- 影响面：`apps/ai-game-creator-shell/src/{App.tsx,styles.css,view/project-development/index.tsx,features/app-shell/*,features/resource-canvas/*}`；用例新增 `tests/runPreviewBrowserOpen.test.tsx`、`tests/runNoticeToast.test.tsx`、`tests/runNoticeShellWiring.test.tsx`（外壳级：替身聊天发提示 → 壳真的渲染浮层）、`tests/gameRunToolbarActionsStyle.test.ts`，改写 `tests/previewActivation.test.tsx`（原断言「聊天里出现已载入运行视图」的地方改为断言 toast 通道 + 对话容器里没有这类提示，并补一条「启动失败走失败色提示且不写对话区」）与 `tests/appSurface/project-development.suite.ts` 的生成任务入口用例。
+- 验证：`appSurface` 全量、AGC 壳目录全量、`npm run typecheck`、`check:native-shells:contract`、`check:encoding`、`git diff --check` 全绿；真机观感未复验。

 ## 2026-09-22 DirectProject 聊天状态显式化：回合三态 + 「在跑吗」唯一派生入口 + 数据流地图
 
 - 背景：DirectProject 聊天框只有三份真相源（`project.jsonl` 历史切片、Thread Manager 运行态事件、本地乐观消息），但「这一轮在跑吗」在四层里各叫一个名字——reducer 的 `turnRunning`、controller 的 `turnBusy`、视图里手拼的 `busy`、投影里的 `active`。定位发送后空窗缺陷时，读代码无法判断某个窗口期的界面表现是否有依据，也说不清谁该信谁。

+- **现象**：`npm run agc` 编到壳 crate 的 build script 时中止，stderr 是 `panicked at build.rs:103: Codex 原生包版本、布局或架构不匹配目标 x86_64-pc-windows-msvc`，stdout 只有 `cargo:rustc-env=AGC_BUILD_TARGET=...`。
+- **原因**：`build_support/codex_bundle.rs` 把随包 Codex CLI 钉在一个固定版本，而本地 `node_modules/@openai/codex-win32-x64/vendor/<target>/codex-package.json` 还停在上一次安装的旧版本。`package-lock.json` 早就升到新版本，缺的只是本地安装；这条判据只看版本元数据，文件齐全、架构正确也照样拦。
+- **处理（现行口径）**：在仓库根目录执行 `npm ci`（不要改成子目录或单包安装），随后 `node_modules/@openai/codex/package.json` 与 vendor 的 `codex-package.json` 版本应当一致。Windows 上 `npm ci` 会先 unlink 整个 `node_modules`：RustRover 的 Tailwind language server / `oxide-helper` 进程会占住 `@tailwindcss/oxide-*.node`，报 `EPERM: operation not permitted, unlink ...` 时先结束这些 helper 再重试，否则会停在半装状态。
+- **验证**：`npm ci` 后 `cargo build --manifest-path apps/ai-game-creator-shell/src-tauri/Cargo.toml` 通过，不再触发该 panic。

 ## 策划聊天不能按可选子节点序号分配消息高度
 
 策划与开发 Agent 共用聊天类名，但布局合同不同。策划新增状态条后，按第二个子节点分配 `1fr` 会把空白给状态条、让消息框随回复增长；只给 `.is-direct-codex` 的状态样式也不会覆盖策划。策划使用纵向 Flex，仅消息列表伸缩，阶段/待处理区域限高滚动；改共用样式时同时核对两种入口。jsdom 交互通过不代表布局正确，须匹配完整 CSS 层叠并用真实浏览器核对空/短/长消息与长待办。窄屏上下堆叠必须在固定外壳内提供工作台滚动容器，两块面板明确限高；低优先级的 `height: auto` 不能覆盖外壳后代规则的 `height: 100%`。布局夹具必须包含窗口外壳与启动器层级，并实际滚动验证输入框可见可操作，不能只检查输入框在聊天面板内部。实时正文/思考不更新持久消息数组，滚动跟随必须覆盖这些独立状态并保留用户上滚门禁；历史消息缺失的时间不得用读取时刻填补。详见 AGC 实施计划的“策划 Agent 对话显示与滚动合同”。
