 ## 项目开发对话（DirectProject）

-**DirectProject 专属聊天模块**:
-AGC 普通项目聊天的独立容器，拥有 DirectProject 的聊天状态、运行态订阅、历史读取、发送队列、附件和中止交互，并把聊天投影交给专属表现层渲染；它不承接 Supervisor、Design Agent 或 Planning V2 的运行态。
-_Avoid_: 把 DirectProject 作为项目总控聊天的一个布尔分支、把四种 Agent 会话抽象成同一事实源

-**项目工作台布局**:
-承载本地项目的资源工作区、项目级工具和独立聊天产品路径的外层界面；布局拥有跨面板的账户/钱包入口，聊天模块只负责项目对话，不嵌套账户展示。
-_Avoid_: 把钱包入口塞进聊天设置、让聊天组件拥有工作台级账户状态

 **项目对话历史**:
 AGC 本地项目内 Codex 原始对话条目的持久集合，是聊天展示、工具卡片和线程恢复注入的唯一持久事实源。
 _Avoid_: 会话缓存、展示态历史、按 UI 需要另存的对话副本

 3. Build with the project's npm script before previewing. The playable entry is the package directory's `dist/index.html`; never report an unbuilt bare-module page as playable. Import assets or configure public assets so all runtime media is included in dist; preview and exports cannot read outside it.
 4. Build a complete playable loop: visible objective, responsive input, meaningful state changes, success or failure feedback, and a reliable restart path where the game needs one.
 5. Fit the active game scene to desktop and mobile viewports without accidental page scrollbars. Reserve deliberate safe space for HUD elements instead of covering interactive content.
+   - **画布居中只能由一处负责。** 使用 `Phaser.Scale.FIT` 与 `autoCenter: Phaser.Scale.CENTER_BOTH` 时，canvas 的直接父容器应使用尺寸明确的普通块布局，不再对同一 canvas 叠加 Grid/Flex 居中、`place-items: center`、自动外边距或居中 transform。Phaser 自动计算的 margin 与 CSS 居中叠加会使竖屏画面向右偏移。
+   - 若决定由 CSS 居中，则显式使用 `autoCenter: Phaser.Scale.NO_CENTER`，由 CSS 独立完成定位；外围页面可以继续使用 Grid/Flex，限制只针对同一 canvas 的重复定位。
+   - 出现偏移先检查游戏自身的 CSS 与 Phaser scale 配置，不添加 AGC 预览容器固定偏移补偿。修改布局后重新构建 dist，在桌面、移动及窗口 resize 后检查 canvas 相对游戏父容器居中（误差不超过 1 CSS px）、画面完整且无意外滚动条；不能仅凭 build 成功宣称布局通过。
 6. Invoke `taonier-art-assets` for every new game brief that needs visual assets. First reuse suitable registered Taonier art; when the brief's required visual elements are missing or unsuitable, call the reviewed `agc_tools` generation/edit workflow in the same task. After the tool returns, wire its relative paths into the game and verify the rendered result. A game with unused generated assets or placeholder emoji/CSS where requested art should appear is not complete. Load media defensively only for genuinely optional effects, and never relabel a local placeholder as platform art.
 7. Let Phaser own the render loop and input dispatch. Avoid duplicate scenes, stale event listeners, and state that survives restart unintentionally.
 8. After a meaningful game change, use the browser playtest Skill and fix issues shown by real evidence before reporting completion.

+- 画布的缩放与居中由 Phaser 或 CSS 中的一方独立负责。`FIT + CENTER_BOTH` 不与同一 canvas 父容器的 Grid/Flex 居中、自动外边距或居中 transform 叠加；使用 CSS 居中时关闭 Phaser 自动居中（`NO_CENTER`）。
+- 在构建后的实际页面检查桌面、移动和 resize：比较 canvas 与游戏父容器的中心，预期居中时水平/垂直误差不超过 1 CSS px，并检查画面没有溢出或意外滚动条。偏移先修游戏 CSS/scale 配置，不用修改 AGC 预览位置掩盖。
