+# 步骤与Flow节点化重构开发方案
+
+## 1. 文档目标
+
+本文不是给现有 `step` 体系再补一层适配，而是把整个执行系统升级成 **flow + node** 体系。目标是从根上解决“数字步骤硬编码”和“key 绑定混用”这两套逻辑并存的问题。
+
+最终设计必须满足：
+
+1. 新增步骤时，只改当前 flow 的定义和节点执行器，不再牵动全局 switch。
+2. 新增完全不同的 flow 时，可以拥有完全不同的节点图、页面源、邮件规则、恢复策略和 UI 表达。
+3. 最终版本不保留 `currentStep` / `stepStatuses` 作为核心状态，不保留 `STEP_*` 作为核心协议，不再让数字步骤充当身份、顺序、状态、历史和消息路由的共同主键。
+4. 方案必须同时覆盖 background、content、sidepanel、日志、历史、自动运行、来源注册、邮件规则、手机号接码、Plus 支付这些强关联模块。
+
+## 2. 重构前实现的真实形态
+
+当前项目不是纯硬编码，而是“**定义层部分动态化，控制层仍然硬编码**”。
+
+| 层 | 现状 | 主要问题 |
+| --- | --- | --- |
+| 状态 | `background.js` 里仍有 `currentStep`、`stepStatuses` | 数字步骤同时承担状态、顺序和恢复锚点 |
+| 协议 | `EXECUTE_STEP`、`STEP_COMPLETE`、`STEP_ERROR`、`SKIP_STEP` | 消息协议仍以数字 step 为核心 |
+| 定义 | `data/step-definitions.js`、`background/steps/registry.js` | 只有 OpenAI 真正注册，且执行仍按数字 id |
+| UI | `sidepanel/sidepanel.js` 按 step 渲染、发送、跳过 | 侧边栏本质上还是数字步骤面板 |
+| 内容脚本 | `content/signup-page.js` 按 `message.step` 分支 | 页面驱动逻辑被 step number 绑死 |
+| 运行态 | `background/runtime-state.js` 已有 `currentNodeId`、`nodeStatuses` | 但仍通过 legacy step 视图回写，双模型并存 |
+| 外围能力 | `shared/source-registry.js`、`shared/flow-capabilities.js`、`background/mail-rule-registry.js` | 已有抽象，但都还没成为唯一事实来源 |
+
+重点文件里最能说明问题的几个点：
+
+- `background.js`：`DEFAULT_STATE`、`setStepStatus()`、`skipStep()`、`runAutoSequenceFromStep()`、`getStepRegistryForState()` 仍把数字 step 当主流程。
+- `background/message-router.js`：`STEP_COMPLETE` / `STEP_ERROR` / `EXECUTE_STEP` / `SKIP_STEP` 还在消息层面锁死 step。
+- `background/runtime-state.js`：已经有 node 相关字段，但还在做 step 兼容派生。
+- `sidepanel/sidepanel.js`：步骤列表、状态展示、手动执行、跳过、自动运行都还围着 step。
+- `flows/openai/mail-rules.js`、`background/mail-rule-registry.js`：已经说明“规则可以 flow 化”，但目前只有 OpenAI 在用。
+
+## 3. 为什么现在的设计有问题
+
+### 3.1 混用了三种身份
+
+现在一个“步骤”同时在扮演：
+
+- 执行身份
+- 顺序编号
+- 状态键
+- 日志标签
+- 历史记录字段
+- 自动运行恢复锚点
+
+这就是后面维护越来越难的根因。只要新增一个节点，往往要同时改定义、状态、消息、UI、日志、历史、恢复逻辑，甚至测试。
+
+### 3.2 只改 key 不够
+
+项目里已经有 `key`，但它并没有真正替代数字 step。
+
+当前状态是：
+
+- `id` 负责顺序和执行
+- `key` 负责局部标识
+- `currentStep` 负责运行态
+- `stepStatuses` 负责状态
+
+这不是“灵活”，这是“双主键混用”。如果只把 `step` 改名成 `node`，不重做控制面，问题不会消失。
+
+### 3.3 不能表达完全不同的 flow
+
+现在 `getStepRegistryForState()` 直接在 `activeFlowId !== openai` 时拒绝执行，这意味着：
+
+- 新 flow 不是“可扩展”，而是“被排除”
+- 每个 flow 都只能往 OpenAI 这套结构里塞
+- 只要一个 flow 的步骤顺序、页面、邮件、恢复策略不同，就会触发大量全局改动
+
+### 3.4 线性 step 模型太弱
+
+现有逻辑默认所有流程都是线性的 1, 2, 3, 4...。
+
+但真实场景里，新的 flow 很可能是：
+
+- 有分支
+- 有可选节点
+- 有重试回路
+- 有条件跳转
+- 有完全不同的外部页面驱动
+
+这种场景下，数字 step 不是天然模型，只是临时排布方式。
+
+### 3.5 相关模块已经开始“各自发明一套”
+
+`runtime-state`、`source-registry`、`flow-capabilities`、`mail-rule-registry`、`navigation-utils` 都已经在做分层，但它们没有统一到一个真正的 workflow 主模型里。
+
+结果就是：局部已经像架构，整体仍像拼接。
+
+## 4. 目标架构

+```
+
+### 4.1 核心标识
+
+| 标识 | 含义 | 规则 |
+| --- | --- | --- |
+| `flowId` | 业务 flow 身份 | 例如 `openai`、`site-a` |
+| `runId` | 一次执行实例 | 同一轮运行内保持不变 |
+| `nodeId` | 节点身份 | 唯一、稳定、可读 |
+| `sourceId` | 页面来源身份 | 负责标签页、页面家族和注入目标 |
+| `driverId` | 内容驱动身份 | 负责某个 source 的命令集 |
+
+### 4.2 目标状态模型
+
+```js
+runtimeState = {
+  flowId: 'openai',
+  runId: 'run_20260515_xxx',
+  workflowVersion: 1,
+  currentNodeId: 'submit-signup-email',
+  nodeStatuses: {
+    'open-chatgpt': 'completed',
+    'submit-signup-email': 'running',
+  },
+  nodeResults: {
+    'open-chatgpt': { completedAt: 1710000000000 },
+  },
+  shared: {},
+  services: {},
+  flows: {
+    openai: {},
+  },
+  runSummary: {
+    finalStatus: 'running',
+    failedNodeId: '',
+    failureReasonCode: '',
+  },
+}
+```
+
+### 4.3 节点模型
+
+```js
+node = {
+  id: 'submit-signup-email',
+  title: '注册并输入邮箱',
+  type: 'task',
+  order: 20, // 仅用于展示，不参与身份
+  sourceId: 'openai-auth',
+  driverId: 'content/signup-page',
+  next: ['fill-password'],
+  retryPolicy: { maxAttempts: 3 },
+  recoveryPolicy: { onFailure: 'restart-node' },
+  ui: { section: 'registration' },
+}
+```
+
+要点：
+
+- `id` 是唯一主键。
+- `order` 只是展示顺序，不再决定执行逻辑。
+- `next` / `recoveryPolicy` 决定流转，不靠全局 step 数组推断。
+- 节点结果、失败原因、重试记录要单独存，不要塞进状态字符串后缀里。
+
+### 4.4 Flow 定义必须是一手真相
+
+`flowDefinition` 应该统一拥有：
+
+- 节点图
+- 节点执行器引用
+- source 绑定
+- driver 绑定
+- 邮件规则引用
+- capability 定义
+- recovery policy
+- settings schema
+
+其他 registry 如果存在，只能是这个定义的运行索引或编译产物，不能自己再维护一份同义信息。
+
+## 5. 新增步骤 / 新增 flow 的接入规则
+
+### 5.1 如果是在同一个 flow 里新增步骤
+
+应该只做这些事：
+
+1. 在该 flow 的 `workflowDefinition` 里新增 node。
+2. 给这个 node 配置 `next`、`retryPolicy`、`recoveryPolicy`、`sourceId`、`driverId`。
+3. 如果它访问了新页面、新邮件规则、新服务，再补对应的 source / driver / mail rule。
+4. UI 从 flow 定义里自动拿到节点标题、顺序和状态展示。
+5. 增加对应测试，不再改全局 step switch。
+
+### 5.2 如果是新加一个完全不同的 flow
+
+应该直接新增一个独立 flow 目录和定义，不去改 OpenAI 的步骤树：
+
+```txt
+flows/<flowId>/
+  workflow.js
+  sources.js
+  mail-rules.js
+  capabilities.js
+  recovery.js
+```
+
+新 flow 的要求是：
+
+- 可以没有手机号接码
+- 可以没有 Plus
+- 可以没有邮件验证码
+- 可以有完全不同的节点顺序和分支
+- 可以有自己的页面源和 driver
+
+核心 engine 不改，改的是 flow 自己。
+
+## 6. 相关模块边界
+
+### 6.1 background
+
+`background.js` 和 `background/message-router.js` 的职责应退回成“调度和校验”，不再自己写业务步骤树。
+
+### 6.2 sidepanel
+
+`sidepanel/sidepanel.js` 只能根据 flow definition 和 capability 结果渲染，不应该再手写 step 编号和 step 顺序判断。
+
+### 6.3 content scripts
+
+`content/signup-page.js` 这类脚本要从“按 step 分支”改成“按 node action / command 分支”。
+
+### 6.4 source / driver
+
+`shared/source-registry.js` 只负责页面来源、标签页生命周期和注入范围。
+
+`driverRegistry` 只负责“这个 source 能接什么命令”。
+
+### 6.5 mail rules
+
+邮件过滤和验证码提取必须是 flow-local 的。`flows/openai/mail-rules.js` 说明这件事已经存在，只是还没推广成整体原则。
+
+### 6.6 auto-run / history / logs
+
+自动运行、日志和历史必须记录 `flowId`、`runId`、`nodeId`，而不是继续写 `step7_failed` 这种混合字符串。
+
+### 6.7 手机接码、Plus、OAuth
+
+这些都不是“通用步骤”，它们是 OpenAI flow 的私有能力。没有第二个 flow 的真实需求时，不要把它们硬抽成全局共享步骤。
+
+## 7. 设计符合性检查
+
+| 检查项 | 是否满足 | 说明 |
+| --- | --- | --- |
+| 不做旧兼容 | 是 | 最终状态不保留 step 作为核心模型 |
+| 新增步骤可维护 | 是 | 只改当前 flow 的 node 和相关依赖 |
+| 新增不同 flow 可维护 | 是 | 独立 flow 定义，不污染 OpenAI |
+| 规范一致 | 是 | 统一使用 `flowId` / `runId` / `nodeId` / `sourceId` |
+| 完整性 | 是 | 覆盖状态、协议、UI、日志、历史、自动运行、来源、邮件 |
+| 正确性 | 基本满足 | 仍需靠分阶段测试验证边界和恢复路径 |
+
+## 8. 方案自身的缺陷与控制点
+
+这份方案本身也有潜在问题，必须提前说明：
+
+1. **抽象过头风险**
+   如果 flow / node / source / driver / mail rule 各自独立维护同一份信息，会重新制造同步成本。控制方式是：`flowDefinition` 必须是一手真相，其它 registry 只能是派生索引。
+
+2. **DSL 复杂度风险**
+   如果节点模型一开始就塞太多字段，后续会变成另一种难维护的配置语言。控制方式是：先保留 `id`、`title`、`type`、`order`、`sourceId`、`driverId`、`next`、`retryPolicy`、`recoveryPolicy`，其余按真实需求再加。
+
+3. **日志和历史膨胀风险**
+   如果把每个节点的所有中间态都原样落盘，历史会很重。控制方式是：日志保留可读摘要，历史保留最终结果 + 关键节点轨迹 + 失败原因码。
+
+4. **UI 复杂度风险**
+   如果 UI 同时展示 flow、node、source、driver、恢复策略，侧边栏会太吵。控制方式是：UI 只展示用户关心的流转和状态，详细调试信息留给开发记录。
+
+5. **边界冲突风险**
+   现在已经存在 `sourceRegistry`、`flowCapabilities`、`mailRuleRegistry`、`runtimeState` 等分层。如果不统一为一套 flow contract，就会继续出现“看起来都对，合起来互相打架”的问题。
+
+## 9. 开发清单
+
+| 阶段 | 开发目标 | 阶段自检 |
+| --- | --- | --- |
+| 1 | 定义最终 schema：`flowId`、`runId`、`nodeId`、`sourceId`、`driverId`、`workflowVersion` | 检查是否还在把 `currentStep` / `stepStatuses` 当核心概念使用 |
+| 2 | 建立 flow definition 和 workflow engine | 检查一个 flow 是否能只靠自己的定义被加载，不改全局 switch |
+| 3 | 替换消息协议 | 检查是否全面切换到 `EXECUTE_NODE` / `NODE_COMPLETE` / `NODE_ERROR` / `SKIP_NODE` 这类命名 |
+| 4 | 改写 runtime / auto-run / recovery | 检查恢复、重试、跳过、暂停是否都基于 `nodeId` 和 `runId` |
+| 5 | 重写 sidepanel | 检查 UI 是否完全从 flow definition 取数据，不再硬编码 step 顺序 |
+| 6 | 迁移 content drivers、邮件规则、来源注册 | 检查新 flow 是否可以拥有完全不同的页面源和邮件规则，而不碰 OpenAI 核心流程 |
+| 7 | 重写日志、历史、账号记录 | 检查是否只记录 `flowId` / `runId` / `nodeId`，不再产出 `stepX_failed` 这类混合状态 |
+| 8 | 删除旧 step 路径和残留逻辑 | 检查仓库中核心路径是否还残留 `EXECUTE_STEP`、`STEP_COMPLETE`、`STEP_ERROR`、`currentStep`、`stepStatuses` |
+
+### 每阶段统一自检
+
+每做完一个阶段，都要执行下面的自检：
+
+1. grep 核心代码，确认没有新的 step 硬编码回流。
+2. 用至少一个 flow 做完整跑通验证。
+3. 用一个“结构完全不同”的 flow 做边界验证。
+4. 检查消息、日志、历史、UI、文档是否一致。
+5. 打开 Markdown 预览，确认中文标题、表格和代码块都没有乱码。
+
+## 10. 最终验收标准
+
+这次重构只有在满足下面条件时才算完成：
+
+- 核心状态不再依赖数字 step。
+- 新步骤只改本 flow，不改全局控制面。
+- 新 flow 可以和 OpenAI 完全不同。
+- background、sidepanel、content、auto-run、logs、history、mail rules、source registry 都在同一套 flow/node 规则下运行。
+- 文档、代码、测试三者描述一致，没有“代码一套、文档一套、UI 一套”的分裂。
+- Markdown 和中文显示无乱码。
+
+结论很直接：这块不能继续修补式演进，必须用 node-based workflow engine 一次性替换掉 step-number 作为核心模型的设计。
+
+## 11. 本次落地后的实现约束
+
+本次重构后，核心运行路径已经按下面规则收敛：
+
+1. background、content、sidepanel 的消息协议只使用 `EXECUTE_NODE`、`NODE_COMPLETE`、`NODE_ERROR`、`SKIP_NODE`。
+2. 核心运行状态只使用 `flowId`、`runId`、`currentNodeId`、`nodeStatuses`。
+3. 账号运行历史的新记录使用 `flowId`、`runId`、`failedNodeId`，失败/停止状态使用 `node:<nodeId>:failed`、`node:<nodeId>:stopped`。
+4. sidepanel 渲染仍可以展示“第几项”的用户文案，但状态合并、按钮执行、跳过、恢复都以 `nodeId` 为主键。
+5. 邮件规则、source registry、driver command 已跟 node 对齐；验证码节点通过 `mailRuleId` 绑定，而不是通过固定步骤号绑定。
+6. 自动运行主循环使用 `runAutoSequenceFromNodeGraph(startNodeId)` 按当前 workflow 的 node 列表推进，不再通过数字序号、`step++` 或 `runAutoSequenceFromNodeOrder` 驱动。
+7. 自动运行恢复、idle 重开、Plus/GPC/GoPay checkout 重建都以目标 `nodeId` 和实际前置节点为锚点；遇到稀疏节点图时不会再依赖不存在的虚拟数字步骤。
+
+阶段 8 自检命令要求核心生产路径不得再命中旧协议和旧状态字段：
+
+```powershell
+rg -n "EXECUTE_STEP|STEP_COMPLETE|STEP_ERROR|SKIP_STEP|STEP_STATUS_CHANGED" background.js background content sidepanel shared flows data
+rg -n "currentStep|stepStatuses|setStepStatus|runAutoSequenceFromStep" background.js background sidepanel content shared flows data
+rg -n "step\d+_failed|step\d+_stopped|step2_stopped|step7_stopped|step8_failed|step9_failed|step10_failed" background.js background
+rg -n "runAutoSequenceFromNodeOrder|currentStartStep|startNodeOrder|while \(step <=|step \+= 1" background.js background
+```
+
+## 12. 后续新增节点的标准入口
+
+同一 flow 新增节点时，按这个顺序开发：
+
+1. 在 `data/step-definitions.js` 的当前 flow 定义里新增 node，并补齐 `nodeId`、`title`、`sourceId`、`driverId`、`command`、`mailRuleId`、`next`。
+2. 在 `background/steps/` 增加或复用节点执行器，并在 registry 构建处按 `executeKey` 注册。
+3. 如果节点需要页面执行，给对应 content driver 增加 `EXECUTE_NODE` command handler。
+4. 如果节点需要邮件验证码，在 `flows/<flowId>/mail-rules.js` 增加 flow-local rule，并通过 `mailRuleId` 绑定。
+5. 增加 node-first 测试，断言消息、状态、历史、UI 都只使用 `nodeId`。
+
+## 13. 后续新增完全不同 flow 的标准入口
+
+新增完全不同 flow 时，不要改 OpenAI 的节点树来“塞进去”，而是新增 flow-local 定义：
+
+```txt
+flows/<flowId>/
+  workflow.js
+  sources.js
+  mail-rules.js
+  capabilities.js
+  recovery.js
+```
+
+落地前必须自检：
+
+- 新 flow 是否可以不包含 OpenAI 私有节点，例如 Plus、手机号接码、OAuth。
+- `sourceId` / `driverId` 是否只服务当前 flow，不污染全局。
+- 邮件规则是否只从当前 flow definition 派生。
+- sidepanel 是否能仅通过 workflow nodes 渲染，不新增全局步骤 switch。
+- 自动运行、历史和日志是否都能用 `flowId/runId/nodeId` 定位。
