-## 12. 本地 helper 运行说明补充
-
-### 12.1 启动命令
-
-Windows：
-
-```powershell
-.\start-hotmail-helper.bat
-```
-
-macOS：
-
-```bash
-chmod +x ./start-hotmail-helper.command
-./start-hotmail-helper.command
-```
-
-如果不使用启动脚本，也可以直接运行：
-
-```bash
-python scripts/hotmail_helper.py
-```
-
-或：
-
-```bash
-python3 scripts/hotmail_helper.py
-```
-
-### 12.2 启动成功标志
-
-启动成功后，终端应输出：
-
-```text
-Hotmail helper listening on http://127.0.0.1:17373
-```
-
-### 12.3 最小排错说明
-
-- 若提示 `Python 3 not found`，说明当前机器没有可用的 Python 3.10+。
-- 若 helper 已启动但扩展仍连不上，先确认 Hotmail 模式切到了 `本地助手`。

+# 2026-04-16 Architecture Refactor Plan
+
+## 目标
+
+在不破坏现有 1~9 步自动化流程、消息流、状态机和测试保护面的前提下，逐步拆分当前超大的主文件，降低后续开发和排障成本。
+
+## 当前事实
+
+- 这是一个无构建步骤的 Manifest V3 扩展。
+- `background.js` 是 classic service worker，当前依赖 `importScripts(...)`。
+- `sidepanel/sidepanel.html` 通过多个 `<script>` 直接加载脚本。
+- 运行态核心链路依赖：
+  - `chrome.storage.session` 保存流程态
+  - `chrome.storage.local` 保存配置态
+  - `chrome.runtime.sendMessage` 贯穿 sidepanel / background / content scripts
+  - `chrome.tabs` / `chrome.webNavigation` / `chrome.debugger` 支撑步骤执行
+- 测试不仅验证行为，还会直接从 `background.js` / `sidepanel.js` / `content/*.js` 按函数名提取源码执行。
+
+## 已确认基线
+
+- `bun test` 当前基线：`84 pass / 0 fail`
+- 关键大文件规模：
+  - `background.js`: 7481 行
+  - `sidepanel/sidepanel.js`: 4531 行
+  - `content/signup-page.js`: 1969 行
+
+## 当前结构压力点
+
+### `background.js`
+
+- 状态/配置、邮箱提供者、Tab 管理、消息路由、自动运行状态机、步骤 1~9 全部集中在单文件。
+- 文件内同时存在：
+  - 纯函数
+  - 网络请求
+  - 存储读写
+  - 浏览器 API 调度
+  - 步骤业务逻辑
+- 风险最高的区域不是“代码长”，而是“跨区域共享状态太多”。
+
+### `sidepanel/sidepanel.js`
+
+- 同时承担：
+  - DOM 查询
+  - 状态同步
+  - 配置读写
+  - 多个 provider 管理器
+  - 按钮事件绑定
+  - background 广播处理
+- Hotmail / LuckMail / iCloud 三块都已经是天然的 feature slice，但仍堆在一个文件里。
+
+## 重构硬约束
+
+### 约束 1：先拆“强内聚功能块”，后拆“流程主干”
+
+优先拆：
+
+- Hotmail 账号池 UI
+- LuckMail 管理 UI
+- iCloud 别名管理 UI
+- CPA / SUB2API 面板桥接层
+
+暂缓拆：
+
+- `executeStep1~9`
+- `autoRunLoop`
+- `handleMessage`
+- `resolveVerificationStep`
+
+原因：这些主干函数既是运行核心，也是当前测试抽取最密集的区域。
+
+### 约束 2：第一阶段尽量不改变被测试函数的“定义位置”
+
+由于现有测试会直接从源文件提取函数源码，第一阶段要避免大规模把被测函数从原文件移走。
+
+### 约束 3：运行边界不能变
+
+以下运行边界必须保持：
+
+- `background.js` 继续是 service worker 入口
+- `sidepanel/sidepanel.html` 继续是 sidepanel 入口
+- content script 注入方式不变
+- 所有 runtime message type 不变
+- storage key 不变
+
+## 目标结构
+
+### 背景层目标
+
+```txt
+background.js
+background/
+  state/
+    settings.js
+    session-state.js
+  runtime/
+    tabs.js
+    command-queue.js
+    logging.js
+    message-router.js
+  providers/
+    hotmail.js
+    luckmail.js
+    icloud.js
+    generated-email.js
+  steps/
+    step1.js
+    step2.js
+    step3.js
+    verification.js
+    step5.js
+    step6.js
+    step7.js
+    step8.js
+    step9.js
+  auto-run/
+    scheduler.js
+    loop.js
+```
+
+### Sidepanel 层目标
+
+```txt
+sidepanel/sidepanel.js
+sidepanel/
+  hotmail-manager.js
+  luckmail-manager.js
+  icloud-manager.js
+  auto-run-ui.js
+  runtime-listeners.js
+  update-service.js
+```
+
+## 分阶段执行顺序
+
+### Phase 1
+
+先拆 `sidepanel` 的强内聚管理区块。
+
+- 先拆 Hotmail manager
+- 再拆 iCloud manager
+- 再拆 LuckMail manager
+
+原因：
+
+- 不触碰主流程状态机
+- 风险主要局限在 sidepanel UI
+- 可以验证“多脚本 + 工厂上下文”的拆分模式
+
+### Phase 2
+
+拆 `background.js` 中和主流程相对解耦的桥接层。
+
+- CPA / SUB2API OAuth 桥接
+- 邮箱 provider 的 API 访问层
+- Cloudflare / Duck / iCloud 生成邮箱层
+
+### Phase 3
+
+拆 `background.js` 中的运行时基础设施。
+
+- tab registry
+- command queue
+- logging
+- storage helpers
+
+### Phase 4
+
+最后拆步骤执行器与 auto-run 主循环。
+
+- `executeStep1~9`
+- `resolveVerificationStep`
+- `autoRunLoop`
+
+## 第一阶段落地策略
+
+本轮先做：
+
+1. 新增 `sidepanel/hotmail-manager.js`
+2. 让 `sidepanel.js` 通过工厂方式接入 Hotmail manager
+3. 不改变 runtime message type
+4. 不改变 Hotmail 区块的 UI 行为
+5. 跑现有测试确认基线仍然成立
+
+## 验收标准
+
+- `bun test` 继续全绿
+- sidepanel Hotmail 区块行为无回归
+- `sidepanel.js` 不再直接承载 Hotmail 账号池的大段渲染和事件逻辑
+- 后续可以按同样模式继续拆 iCloud / LuckMail

+# 项目完整链路说明
+
+本文档面向 AI 与开发者，目标是让阅读者在最短时间内理解“项目做什么、怎么跑、数据怎么流、功能链路怎么串”，从而在新增功能时不漏逻辑、不误改边界。
+
+使用建议：
+
+1. 先阅读 [项目文件结构说明.md](c:/Users/projectf/Downloads/codex注册扩展/项目文件结构说明.md)
+2. 再阅读本文
+3. 最后阅读 [项目开发规范（AI协作）.md](c:/Users/projectf/Downloads/codex注册扩展/项目开发规范（AI协作）.md)
+
+## 1. 项目目标
+
+这是一个 Chrome 扩展，用于自动执行一整套 OpenAI / ChatGPT OAuth 注册与登录流程。
+
+它的核心价值不是“打开一个页面点几个按钮”，而是把下面这些环节串成一条完整可恢复的自动化链路：
+
+- 生成或选取注册邮箱
+- 打开 ChatGPT / OpenAI 注册入口
+- 提交邮箱和密码
+- 轮询注册验证码
+- 填写姓名和生日
+- 刷新 OAuth 链接并登录
+- 轮询登录验证码
+- 自动确认 OAuth 同意页
+- 把 localhost 回调提交到 CPA 或 SUB2API
+
+## 2. 核心运行参与者
+
+### 2.1 Sidepanel
+
+[sidepanel/sidepanel.html](c:/Users/projectf/Downloads/codex注册扩展/sidepanel/sidepanel.html) + [sidepanel/sidepanel.js](c:/Users/projectf/Downloads/codex注册扩展/sidepanel/sidepanel.js)
+
+职责：
+
+- 展示配置与步骤状态
+- 接收用户输入
+- 向后台发送命令
+- 接收后台广播并更新 UI
+- 动态渲染步骤列表
+- 在日志区标题下方汇总展示最近账号运行历史
+
+### 2.2 Background Service Worker
+
+[background.js](c:/Users/projectf/Downloads/codex注册扩展/background.js)
+
+职责：
+
+- 扩展后台入口
+- 装配所有模块
+- 统一承接 runtime message
+- 协调步骤执行
+- 管理状态、自动运行、标签页与内容脚本通信
+
+### 2.3 Content Scripts
+
+[content](c:/Users/projectf/Downloads/codex注册扩展/content)
+
+职责：
+
+- 在目标网页上执行 DOM 交互
+- 读取邮件内容或页面状态
+- 将步骤成功/失败状态上报给后台
+
+### 2.4 Helper / Utils / Provider Logic
+
+分布在根目录和 `background/` 下。
+
+职责：
+
+- 抽离第三方邮箱 provider 的纯逻辑
+- 抽离邮件匹配与验证码提取
+- 抽离共享验证码流程、自动运行流程和运行时基础设施
+
+## 3. 入口与装配关系
+
+### 3.1 扩展入口
+
+[manifest.json](c:/Users/projectf/Downloads/codex注册扩展/manifest.json) 声明：
+
+- `background.service_worker = background.js`
+- `side_panel.default_path = sidepanel/sidepanel.html`
+- 多组内容脚本自动注入规则
+
+### 3.2 背景层装配
+
+[background.js](c:/Users/projectf/Downloads/codex注册扩展/background.js) 通过 `importScripts(...)` 依次加载：
+
+- 共享数据与纯工具
+- provider 纯逻辑
+- 后台桥接层
+- 后台共享流程层
+- 后台运行时与消息路由层
+- 步骤执行模块
+
+因此 `background.js` 现在更像：
+
+- 常量定义中心
+- 模块依赖装配器
+- 极少量保留函数
+- Chrome 事件挂接入口
+
+### 3.3 步骤注册
+
+[data/step-definitions.js](c:/Users/projectf/Downloads/codex注册扩展/data/step-definitions.js) 提供共享步骤元数据。  
+[background/steps/registry.js](c:/Users/projectf/Downloads/codex注册扩展/background/steps/registry.js) 负责把“步骤元数据”映射到“步骤执行器”。
+
+这意味着：
+
+- 步骤顺序靠 `order`
+- 步骤文件名靠语义
+- 新增步骤时不需要重命名后续文件
+
+## 4. 状态与存储链路
+
+### 4.1 `chrome.storage.session`
+
+保存运行态：
+
+- 当前步骤状态
+- OAuth 链接
+- 当前邮箱 / 密码
+- localhost 回调地址
+- 自动运行轮次信息
+- 标签注册表
+- 最近打开的来源地址
+- LuckMail 当前运行时选择
+
+### 4.2 `chrome.storage.local`
+
+保存持久配置与账号运行历史：
+
+- CPA / SUB2API 配置
+- 邮箱 provider 配置
+- Hotmail 账号池
+- Cloudflare / Temp Email 设置
+- iCloud 相关偏好
+- LuckMail API 配置
+- 自动运行默认配置
+- 账号运行历史 `accountRunHistory`
+- 账号运行历史 txt 留档开关与 helper 地址
+
+当启用了独立的账号运行历史 txt 留档配置时，账号运行历史会通过 [scripts/hotmail_helper.py](c:/Users/projectf/Downloads/codex注册扩展/scripts/hotmail_helper.py) 追加写入 `data/account-run-history.txt` 文本文件，便于离线留档。
+这条配置链路独立于 `mailProvider` 和 Hotmail 的接码模式。
+
+### 4.3 状态广播
+
+后台通过 runtime message 向 sidepanel 广播：
+
+- `LOG_ENTRY`
+- `STEP_STATUS_CHANGED`
+- `DATA_UPDATED`
+- `AUTO_RUN_STATUS`
+- `ICLOUD_LOGIN_REQUIRED`
+- `ICLOUD_ALIASES_CHANGED`
+
+## 5. 内容脚本通信链路
+
+### 5.1 READY 机制
+
+[content/utils.js](c:/Users/projectf/Downloads/codex注册扩展/content/utils.js) 在脚本加载后会发送 `CONTENT_SCRIPT_READY`。
+
+后台收到后会：
+
+- 注册当前来源对应的 tab
+- 标记 ready
+- 冲刷排队命令
+
+### 5.2 队列与重试
+
+[background/tab-runtime.js](c:/Users/projectf/Downloads/codex注册扩展/background/tab-runtime.js) 负责：
+
+- `queueCommand`
+- `flushCommand`
+- `sendTabMessageWithTimeout`
+- `sendToContentScriptResilient`
+- `sendToMailContentScriptResilient`
+
+这保证了：
+
+- 页面切换导致脚本暂时失联时，后台不会立刻误判彻底失败
+- 邮箱页或注册页能在注入恢复后继续执行
+
+## 6. 手动步骤完整链路
+
+### Step 1
+
+文件：
+
+- [background/steps/open-chatgpt.js](c:/Users/projectf/Downloads/codex注册扩展/background/steps/open-chatgpt.js)
+- [content/signup-page.js](c:/Users/projectf/Downloads/codex注册扩展/content/signup-page.js)
+
+流程：
+
+1. 后台打开 ChatGPT 官网
+2. 等待注册入口页内容脚本就绪
+3. 标记 Step 1 完成
+
+### Step 2
+
+文件：
+
+- [background/steps/submit-signup-email.js](c:/Users/projectf/Downloads/codex注册扩展/background/steps/submit-signup-email.js)
+
+流程：
+
+1. 解析本轮应使用的邮箱
+2. 打开或复用注册页
+3. 点击注册入口并提交邮箱
+4. 等待邮箱提交后的真实落地页
+5. 如果进入密码页，则继续执行 Step 3
+6. 如果直接进入邮箱验证码页，则自动跳过 Step 3 并进入 Step 4
+
+### Step 3
+
+文件：
+
+- [background/steps/fill-password.js](c:/Users/projectf/Downloads/codex注册扩展/background/steps/fill-password.js)
+
+流程：
+
+1. 生成或读取密码
+2. 更新运行态密码
+3. 记录账号快照
+4. 让内容脚本填写密码并继续
+
+### Step 4 / Step 7
+
+文件：
+
+- [background/steps/fetch-signup-code.js](c:/Users/projectf/Downloads/codex注册扩展/background/steps/fetch-signup-code.js)
+- [background/steps/fetch-login-code.js](c:/Users/projectf/Downloads/codex注册扩展/background/steps/fetch-login-code.js)
+- [background/verification-flow.js](c:/Users/projectf/Downloads/codex注册扩展/background/verification-flow.js)
+
+这两步共享验证码主流程：
+
+1. 确定 provider
+2. 必要时重发验证码
+3. 轮询邮箱或 API
+4. 提取验证码
+5. 回填页面
+6. 若页面拒绝，则重试或回退
+
+补充行为：
+
+- `2925` provider 会拉长单轮轮询窗口，并关闭 Step 4 / 7 的自动重发间隔，减少因邮件延迟过早判负。
+- CPA 模式下，Step 7 在真正回填登录验证码前，会先刷新最新 OAuth 地址并快速重走一次 Step 6，降低验证码等待过久导致 OAuth 过期的概率。
+
+### Step 5
+
+文件：
+
+- [background/steps/fill-profile.js](c:/Users/projectf/Downloads/codex注册扩展/background/steps/fill-profile.js)
+
+流程：
+
+1. 生成随机姓名和生日
+2. 内容脚本填写资料并点击“完成帐户创建”
+3. 点击后立即上报 Step 5 完成，不再等待页面结果
+4. 自动运行在进入 Step 6 前仅额外等待当前页面加载完成，不再在 Step 5 阶段接管 ChatGPT 跳转或 onboarding 跳过
+
+### Step 6
+
+文件：
+
+- [background/steps/oauth-login.js](c:/Users/projectf/Downloads/codex注册扩展/background/steps/oauth-login.js)
+
+流程：
+
+1. 清理登录前 Cookie
+2. 通过 CPA / SUB2API 刷新 OAuth 地址
+3. 打开最新 OAuth 链接
+4. 登录
+5. 确保真正进入验证码页
+6. 如果未进入验证码页，则按可恢复逻辑最多重试 3 次
+7. 自动运行一旦进入步骤 6 之后的链路，若后续步骤报错且认证页未进入 `https://auth.openai.com/add-phone`，则统一回到步骤 6 重新开始授权流程
+
+### Step 8
+
+文件：
+
+- [background/steps/confirm-oauth.js](c:/Users/projectf/Downloads/codex注册扩展/background/steps/confirm-oauth.js)
+
+流程：
+
+1. 监听 localhost callback
+2. 准备 OAuth 同意页
+3. 尝试多轮点击“继续”
+4. 一旦捕获 localhost callback，写入状态并完成步骤
+
+### Step 9
+
+文件：
+
+- [background/steps/platform-verify.js](c:/Users/projectf/Downloads/codex注册扩展/background/steps/platform-verify.js)
+
+流程：
+
+1. 校验 localhost callback 是否有效
+2. 判断是 CPA 还是 SUB2API
+3. 打开相应后台
+4. 提交回调地址
+5. 仅当出现精确成功徽标，且该徽标不是红色/错误态、页面上也没有同时可见的失败提示时，才判定成功
+6. 识别 `认证失败:*`、`认证失败: timeout of 30000ms exceeded`、`回调 URL 提交失败: oauth flow is not pending` 等失败提示并立即报错
+7. 完成平台侧验证
+8. 追加账号运行历史成功记录
+9. 做成功后的清理与标记
+
+## 7. 邮箱与 provider 链路
+
+### 7.1 生成邮箱
+
+文件：
+
+- [background/generated-email-helpers.js](c:/Users/projectf/Downloads/codex注册扩展/background/generated-email-helpers.js)
+
+支持：
+
+- Duck
+- Cloudflare
+- Cloudflare Temp Email
+- iCloud 隐私邮箱
+
+### 7.2 Hotmail
+
+组成：
+
+- [hotmail-utils.js](c:/Users/projectf/Downloads/codex注册扩展/hotmail-utils.js)
+- [microsoft-email.js](c:/Users/projectf/Downloads/codex注册扩展/microsoft-email.js)
+- [scripts/hotmail_helper.py](c:/Users/projectf/Downloads/codex注册扩展/scripts/hotmail_helper.py)
+
+模式：
+
+- API 对接
+- 本地 helper
+
+补充：
+
+- 本地 helper 除了收信与验证码读取，还提供账号运行历史文本追加接口。
+- 账号运行历史 txt 留档由独立配置控制，不再绑定 Hotmail 的本地助手模式。
+
+### 7.3 LuckMail
+
+组成：
+
+- [luckmail-utils.js](c:/Users/projectf/Downloads/codex注册扩展/luckmail-utils.js)
+- LuckMail 相关后台领域逻辑仍在 [background.js](c:/Users/projectf/Downloads/codex注册扩展/background.js)
+
+### 7.4 iCloud
+
+组成：
+
+- [icloud-utils.js](c:/Users/projectf/Downloads/codex注册扩展/icloud-utils.js)
+- [content/icloud-mail.js](c:/Users/projectf/Downloads/codex注册扩展/content/icloud-mail.js)
+
+## 8. 自动运行完整链路
+
+文件：
+
+- [background/auto-run-controller.js](c:/Users/projectf/Downloads/codex注册扩展/background/auto-run-controller.js)
+
+流程：
+
+1. 读取总轮数与模式
+2. 计算是否从中断点继续
+3. 每轮执行前重置必要运行态
+4. 执行 `runAutoSequenceFromStep`
+   - 步骤 6 内部仍保留登录态恢复的有限重试
+   - 一旦进入步骤 6~9，遇到报错且认证流程未进入 `add-phone`，则自动回到步骤 6 无限重开，直到成功、手动停止或命中 `add-phone`
+5. 如果失败，根据设置决定：
+   - 立即停止
+   - 当前轮重试
+   - 下一轮继续
+6. 当前轮最终失败或被停止时，追加账号运行历史记录
+7. 如果配置了线程间隔，则挂计时计划
+8. 所有轮次结束后输出汇总
+
+## 9. 新增功能时最容易漏掉的地方

+# 项目开发规范（AI协作）
+
+本文档是面向 AI 与开发者的项目开发规范。
+
+阅读顺序要求：
+
+1. [项目文件结构说明.md](c:/Users/projectf/Downloads/codex注册扩展/项目文件结构说明.md)
+2. [项目完整链路说明.md](c:/Users/projectf/Downloads/codex注册扩展/项目完整链路说明.md)
+3. 当前文件
+
+原则：
+
+- 目标是“让项目更清晰、更可维护、更可测试”，不是单纯把代码拆碎。
+- 重构优先考虑稳定性、职责边界与可理解性。
+- 任何新增功能都必须沿现有分层接入，禁止重新堆回巨石文件。
+
+## 1. 架构原则
+
+### 1.1 背景层原则
+
+- [background.js](c:/Users/projectf/Downloads/codex注册扩展/background.js) 应尽量保持为入口壳、装配层和少量保留函数。
+- 业务流程优先放到：
+  - `background/steps/`
+  - `background/*.js` 的共享模块
+- 不要把新 provider、大段自动运行逻辑、大段消息分发逻辑直接写回 `background.js`。
+
+### 1.2 步骤原则
+
+- 每个步骤必须有清晰边界。
+- 步骤文件应优先使用语义化名称，不再使用 `stepX.js` 命名。
+- 步骤顺序统一由：
+  - [data/step-definitions.js](c:/Users/projectf/Downloads/codex注册扩展/data/step-definitions.js)
+  - [background/steps/registry.js](c:/Users/projectf/Downloads/codex注册扩展/background/steps/registry.js)
+ 共同管理。
+
+### 1.3 前后端步骤定义共享原则
+
+- 任何步骤标题、顺序、key 变更，必须优先改 [data/step-definitions.js](c:/Users/projectf/Downloads/codex注册扩展/data/step-definitions.js)
+- 不允许只改 sidepanel 文案而不改共享定义
+- 不允许只改 registry 而不改共享定义
+
+## 2. 模块边界规则
+
+### 2.1 可以继续增长的文件
+
+允许增长，但必须保持边界清晰：
+
+- provider 领域实现文件
+- 某个单独步骤文件
+- 某个单独 manager 文件
+
+### 2.2 不应该继续膨胀的文件
+
+- [background.js](c:/Users/projectf/Downloads/codex注册扩展/background.js)
+- [sidepanel/sidepanel.js](c:/Users/projectf/Downloads/codex注册扩展/sidepanel/sidepanel.js)
+
+如果在这两个文件里新增了大段逻辑，应优先判断是否应该下沉到模块。
+
+## 3. 新增功能接入规范
+
+### 3.1 新增步骤
+
+必须同步检查：
+
+1. 新增步骤文件到 `background/steps/`
+2. 更新 [data/step-definitions.js](c:/Users/projectf/Downloads/codex注册扩展/data/step-definitions.js)
+3. 更新 [background/steps/registry.js](c:/Users/projectf/Downloads/codex注册扩展/background/steps/registry.js)
+4. 检查 sidepanel 动态步骤渲染是否已自动覆盖
+5. 检查 auto-run 是否需要纳入此步骤
+6. 检查状态流、回退流、日志流是否完整
+7. 补测试
+
+### 3.2 新增 provider
+
+必须同步检查：
+
+1. 是否有纯工具模块
+2. 是否需要 background provider 调度逻辑
+3. 是否需要 sidepanel 配置项
+4. 是否需要 Step 4 / 7 验证码链路接入
+5. 是否需要成功收尾逻辑
+6. 是否需要 README 与完整链路文档更新
+
+### 3.3 新增配置项
+
+必须同步检查：
+
+1. 默认值
+2. 归一化
+3. 导入导出
+4. state restore
+5. sidepanel UI
+6. 是否挂在正确的职责域下
+7. 文档
+
+## 4. 测试规范
+
+### 4.1 原则
+
+- 任何结构性重构都必须伴随测试迁移或新增。
+- 优先测试：
+  - 模块是否接入
+  - 核心纯函数是否仍可验证
+  - 回退/停止/异常传播是否仍正确
+
+### 4.2 不允许的做法
+
+- 修改结构后不补测试
+- 只跑局部测试，不跑全量回归
+- 为了通过测试而破坏实际运行边界
+
+### 4.3 最低要求
+
+完成一次结构性改动后，至少执行：
+
+```bash
+bun test
+```
+
+## 5. 文档更新规范
+
+### 5.1 必须更新文档的场景
+
+- 文件新增/删除/重命名  
+  更新 [项目文件结构说明.md](c:/Users/projectf/Downloads/codex注册扩展/项目文件结构说明.md)
+- 功能链路变化  
+  更新 [项目完整链路说明.md](c:/Users/projectf/Downloads/codex注册扩展/项目完整链路说明.md)
+- 开发流程、边界、约束变化  
+  更新当前文件
+
+### 5.2 文档更新要求
+
+- 不能只改代码不改文档
+- 不能只改文档标题不改正文细节
+- 不能让结构文档漏文件
+- 不能让链路文档落后于真实实现
+
+## 6. 命名规范
+
+### 6.1 文件命名
+
+- 步骤文件使用语义化名称
+- 工具文件按职责命名
+- 不要再新增 `misc.js`、`temp.js`、`new.js`、`helper2.js` 这种模糊文件名
+
+### 6.2 key 命名
+
+- 步骤 key 使用短语义英文 kebab-case
+- message type 保持稳定，新增时优先语义化大写常量风格
+
+## 7. 代码风格与实现要求
+
+- 优先复用现有模块，不重复发明一套新流程
+- 共享逻辑先提公共层，再让步骤层调用
+- 代码新增后应尽量减少主文件体积，而不是只做“形式拆分”
+- 观测、留档、日志、导出这类横切能力必须优先挂在独立配置域下，不能借某个 provider 的业务模式开关隐式控制
+- 保留少量兼容型薄包装是允许的，但必须有明确目的：
+  - 运行时装配
+  - 测试迁移过渡
+- 如果某个薄包装已经没有存在意义，应在后续重构中清掉
+
+## 8. AI 开发时的自检清单
+
+每次修改后至少自问：
+
+1. 我这次新增逻辑是不是应该下沉到模块？
+2. 我有没有破坏共享步骤定义？
+3. 我有没有漏掉 auto-run / sidepanel / message-router 其中之一？
+4. 我有没有补或迁移测试？
+5. 我有没有更新三份根目录文档？
+6. 我新增或修改的文件是否有可见乱码？
+
+## 9. 完成标准
+
+当满足以下条件时，可以视为一次合格开发完成：
+
+- 代码职责边界清晰
+- 新旧功能链路完整
+- 全量测试通过
+- 三份根目录文档已同步
+- 没有可见乱码
+
+## 10. 特别要求
+
+以后每次开发，如果影响到项目结构、功能链路或开发边界：
+
+- 必须同步检查并在必要时更新：
+  - [项目文件结构说明.md](c:/Users/projectf/Downloads/codex注册扩展/项目文件结构说明.md)
+  - [项目完整链路说明.md](c:/Users/projectf/Downloads/codex注册扩展/项目完整链路说明.md)
+  - [项目开发规范（AI协作）.md](c:/Users/projectf/Downloads/codex注册扩展/项目开发规范（AI协作）.md)
+
+这是硬要求，不是建议。
