feat: ChatGPT auto-registration system with CPA integration

- Full ChatGPT registration flow (signup -> password -> OTP -> create_account)
- OAuth via chatgpt.com to bypass add_phone requirement
- Sentinel token with turnstile fallback (t="0")
- Cross-domain cookie deduplication for curl_cffi
- cfmail integration for temporary email + OTP verification
- Auto-sync registered accounts to CPA backend
- Dashboard for real-time monitoring
- Multi-threaded concurrent registration support

+# zhuce6 Project AGENTS
+
+## 项目定位
+
+- `zhuce6` 是自用 ChatGPT 注册与治理仓库.
+- 当前主线是单池 + backend API.
+- `main.py` 是统一入口, 负责 `init / doctor / run / stop / status`, FastAPI 路由, register loop, 以及 `cleanup / validate / rotate / register` 后台任务装配.
+- 主 Dashboard 路径是 `GET /zhuce6`, 页面文件位于 `dashboard/zhuce6.html`.
+- 支持两类 full backend:
+  - `cpa`
+  - `sub2api`
+- `cfmail` 是默认 mailbox provider 主线.
+
+## 首先阅读什么
+
+1. `README.md`
+2. `docs/TROUBLESHOOTING.md`
+3. `docs/CONFIG_REFERENCE.md`
+4. `main.py`
+5. 再按任务进入 `core/`, `ops/`, `platforms/chatgpt/`, `dashboard/`
+
+## 正确入口认知
+
+所有实施 agent 都应从以下主线理解项目:
+
+```bash
+uv run python main.py init
+uv run python main.py doctor --fix
+uv run python main.py --mode lite
+# 或
+uv run python main.py --mode full
+```
+
+### 主线组合
+
+- `lite + cfmail + register`
+- `full + cpa`
+- `full + sub2api`
+
+### 不要再按旧叙事理解
+
+以下内容不再是项目主线认知:
+
+- 历史两阶段池叙事
+- 旧后台同步任务
+- 旧归档主线
+- 容器优先入口认知
+- CPA-only 的 full 模式理解
+
+## 架构说明
+
+### 核心模块职责
+
+- `main.py`: 统一 CLI 入口, FastAPI 应用创建, runtime mode 切换, 生命周期命令.
+- `core/`: settings, doctor, setup wizard, cfmail, proxy pool, mailbox 抽象, 路径与共享基础设施.
+- `platforms/chatgpt/`: ChatGPT 注册链, HTTP / OAuth 客户端, pool 写入与平台适配.
+- `ops/`: `cleanup`, `validate`, `rotate` 与相关治理逻辑.
+- `dashboard/`: `/zhuce6` 页面与 API 输出.
+- `scripts/`: 独立脚本, 例如 cfmail 自动化与辅助工具.
+- `tests/`: pytest 测试集.
+
+### 运行模式说明
+
+- `full`: 启动 Dashboard / API, 并按配置启用治理任务与 register.
+- `dashboard`: 只启动 Dashboard / API.
+- `lite`: 轻量运行模式, 适合只跑注册主线.
+- `register-loop`: 只运行持续注册循环.
+- `burst-scheduler`: 只运行批次调度注册.
+
+## 实施规则
+
+- 文档与代码都要围绕唯一正确入口: `init -> doctor --fix -> run`.
+- `full` 必须显式区分 `backend=cpa` 与 `backend=sub2api`.
+- `cfmail` 配置优先最小输入, 自动推导 Cloudflare 资源.
+- 不要把临时排障口径写回长期文档.
+- 不要把外部部署背景重新写成 repo 主逻辑.
+
+## 验证规则
+
+```bash
+cd <PROJECT_ROOT>
+
+export ZHUCE6_BASE_URL="http://<dashboard-host>:<dashboard-port>"
+
+PYTHONPATH=. uv run pytest -q -s
+curl -sS "$ZHUCE6_BASE_URL/api/summary" | python3 -m json.tool | head -n 80
+curl -sS "$ZHUCE6_BASE_URL/api/runtime" | python3 -m json.tool | head -n 80
+curl -sS "$ZHUCE6_BASE_URL/api/health/dependencies" | python3 -m json.tool | head -n 80
+python3 - <<'PY'
+import json
+import os
+import urllib.request
+
+base_url = os.environ["ZHUCE6_BASE_URL"].rstrip("/")
+with urllib.request.urlopen(f"{base_url}/api/runtime") as resp:
+    runtime = json.load(resp)
+registered = set(runtime.get("registered_tasks") or [])
+assert ("sy" + "nc") not in registered, sorted(registered)
+assert "register" in registered or runtime.get("runtime_mode") in {"dashboard"}, runtime
+print(sorted(registered))
+PY
+curl -sS "$ZHUCE6_BASE_URL/zhuce6" | head
+```
+
+## 文档维护范围
+
+优先维护:
+
+- `README.md`
+- `AGENTS.md`
+- `docs/TROUBLESHOOTING.md`
+- `docs/CONFIG_REFERENCE.md`
+- `docs/CODEX_PROVIDER_PROTOCOL_NOTES.md`
+
+阶段性说明若已被长期文档吸收, 应及时清理.

+# zhuce6 - ChatGPT 自动注册系统
+
+自动注册 ChatGPT 账号并同步至 CPA (CLI Proxy API) 管理后端。
+
+## 功能
+
+- 全自动 ChatGPT 账号注册（邮箱注册 + OTP 验证 + 账号创建）
+- 通过 chatgpt.com OAuth 流程获取 access_token，绕过手机号验证
+- Cloudflare Email Worker (cfmail) 临时邮箱支持
+- 注册账号自动同步至 CPA 后端
+- Dashboard 实时监控注册状态
+- 支持多线程并发注册
+- 代理池支持（直接代理或 Clash 配置）
+
+## 环境要求
+
+- Python >= 3.11
+- Node.js >= 18（用于 sentinel 相关功能）
+- [uv](https://docs.astral.sh/uv/) 包管理器
+
+## 快速开始
+
+### 1. 安装依赖
+
+```bash
+uv sync
+```
+
+### 2. 配置环境变量
+
+复制示例配置并编辑：
+
+```bash
+cp .env.example .env
+```
+
+编辑 `.env`，至少配置以下内容：
+
+```bash
+# 运行模式
+ZHUCE6_RUNTIME_MODE=full
+ZHUCE6_REGISTER_ENABLED=true
+
+# 注册代理（必须，建议使用海外代理）
+ZHUCE6_REGISTER_PROXY=http://user:pass@host:port
+
+# 注册线程数和间隔
+ZHUCE6_REGISTER_THREADS=2
+ZHUCE6_REGISTER_SLEEP_MIN=5
+ZHUCE6_REGISTER_SLEEP_MAX=15
+
+# 代理池（无代理池可禁用）
+ZHUCE6_ENABLE_PROXY_POOL=0
+ZHUCE6_PROXY_POOL_CONFIG=
+
+# CPA 后端（可选）
+ZHUCE6_BACKEND=cpa
+ZHUCE6_CPA_MANAGEMENT_BASE_URL=http://127.0.0.1:8317/v0/management
+ZHUCE6_CPA_MANAGEMENT_KEY=your_key
+
+# cfmail Cloudflare 配置（用于通过启动检查，实际邮箱由 cfmail_accounts.json 控制）
+ZHUCE6_CFMAIL_API_TOKEN=your_cf_api_token
+ZHUCE6_CFMAIL_CF_ACCOUNT_ID=your_account_id
+ZHUCE6_CFMAIL_CF_ZONE_ID=your_zone_id
+ZHUCE6_CFMAIL_WORKER_NAME=your_worker_name
+ZHUCE6_CFMAIL_ZONE_NAME=your_domain.com
+```
+
+### 3. 配置 cfmail 邮箱服务
+
+创建 `config/cfmail_accounts.json`（参考 `config/cfmail_accounts.example.json`）：
+
+```json
+{
+  "accounts": [
+    {
+      "name": "my-mail",
+      "worker_domain": "your-email-api.example.com",
+      "email_domain": "example.com",
+      "admin_password": "your_admin_password",
+      "enabled": true
+    }
+  ]
+}
+```
+
+cfmail 需要一个已部署的 Cloudflare Email Worker 服务，用于创建临时邮箱和接收 OTP 验证码。
+
+### 4. 启动服务
+
+```bash
+# 完整模式（Dashboard + 注册）
+uv run python main.py run --mode full
+
+# 仅 Dashboard
+uv run python main.py run --mode dashboard
+
+# 指定线程数
+uv run python main.py run --mode full --register-threads 4
+
+# 指定端口
+uv run python main.py run --host 0.0.0.0 --port 8080
+```
+
+### 5. 访问 Dashboard
+
+启动后访问 `http://127.0.0.1:8000/zhuce6` 查看注册状态。
+
+API 端点：
+- `GET /healthz` - 健康检查
+- `GET /api/runtime` - 运行时状态
+- `GET /api/summary` - 注册统计
+- `GET /api/health/dependencies` - 依赖状态（cfmail / CPA / 代理池）
+
+## 运行模式
+
+| 模式 | 说明 |
+|------|------|
+| `full` | Dashboard + 后台任务 + 注册循环 |
+| `dashboard` | 仅 Dashboard + 后台任务，不注册 |
+| `lite` | Dashboard + 注册，禁用清理/验证等后台任务 |
+| `register-loop` | 仅注册循环，无 Dashboard |
+| `burst-scheduler` | 批量注册调度器 |
+
+## 其他命令
+
+```bash
+# 初始化配置向导
+uv run python main.py init
+
+# 检查环境
+uv run python main.py doctor
+
+# 停止所有进程
+uv run python main.py stop
+
+# 查看进程状态
+uv run python main.py status
+```
+
+## 目录结构
+
+```
+config/          # 配置文件（cfmail 账号等）
+core/            # 核心模块（注册循环、设置、邮箱等）
+dashboard/       # Dashboard 前端
+platforms/       # 平台实现（ChatGPT 注册逻辑）
+ops/             # 运维操作（验证、清理、轮换等）
+pool/            # 注册成功的凭证文件（自动生成）
+state/           # 运行时状态文件（自动生成）
+logs/            # 日志文件（自动生成）
+```
+
+## 注意事项
+
+- 注册代理建议使用住宅代理以降低风控风险
+- cfmail 邮箱域名建议使用 `.com` 等常见 TLD
+- 注册成功的凭证保存在 `pool/` 目录，格式为 JSON
+- 如配置了 CPA 后端，凭证会自动同步

+# ChatGPT Provider Protocol Notes
+
+本文档记录分享版仓库仍然保留的 provider 协议约定. 当前只保留 `cfmail` 基线, 不再维护历史第三方邮箱 provider 的接入说明.
+
+## 1. cfmail mailbox create
+
+- Method: `POST`
+- Endpoint: `https://<worker-domain>/admin/new_address`
+- Headers:
+  - `x-admin-auth: <admin-password>`
+  - `Accept: application/json`
+  - `Content-Type: application/json`
+- Request body:
+
+```json
+{
+  "enablePrefix": true,
+  "name": "oc<random>",
+  "domain": "mail.example.com"
+}
+```
+
+- Success payload:
+
+```json
+{
+  "address": "ocxxxx@mail.example.com",
+  "jwt": "<mailbox-jwt>"
+}
+```
+
+## 2. cfmail mail list
+
+- Method: `GET`
+- Endpoint: `https://<worker-domain>/api/mails?limit=<n>&offset=0`
+- Headers:
+  - `Authorization: Bearer <mailbox-jwt>`
+  - `Accept: application/json`
+
+典型返回中会包含 `results`, 每条邮件通常至少应能提供唯一 id 与原始正文片段.
+
+## 3. OTP 提取约定
+
+- 只处理当前 mailbox 的新邮件.
+- 默认提取 6 位数字验证码.
+- `before_ids` 用于忽略旧邮件.
+- 若列表接口先看到旧邮件, `wait_for_code()` 会扩大窗口后继续轮询.
+
+## 4. 错误分类
+
+### 4.1 mailbox create 侧
+
+- `transport_error`: 网络抖动或上游连接失败, 可重试.
+- `HTTP 4xx`: 配置错误, 鉴权失败, 或上游资源不可用.
+- `HTTP 5xx`: 上游临时错误, 应有限重试.
+
+### 4.2 mail list / wait_otp 侧
+
+- 列表可达但无新邮件: 记为 `wait_otp` 路径继续轮询.
+- 列表接口异常: 记为 mailbox 侧问题, 先检查 worker 与 auth.
+- 解析不到验证码: 检查邮件正文模板与关键词过滤.
+
+## 5. 候选号 readiness
+
+主池治理依赖两类探测:
+
+- quota probe
+- real service probe
+
+分享版文档只保留这个抽象边界, 具体实现细节请以当前 `ops/rotate.py` 与 `ops/validate.py` 为准.

+
+## 1. 主线组合
+

+关键变量:
+
+- `ZHUCE6_REGISTER_MAIL_PROVIDER=cfmail`
+- `ZHUCE6_REGISTER_PROXY`
+- `ZHUCE6_CFMAIL_API_TOKEN`
+- `ZHUCE6_CFMAIL_CF_ACCOUNT_ID`

+- `ZHUCE6_CPA_MANAGEMENT_BASE_URL`
+- `ZHUCE6_CPA_MANAGEMENT_KEY`
+
+### full + sub2api
+

+- 认证二选一:
+  - `ZHUCE6_SUB2API_API_KEY`
+  - `ZHUCE6_SUB2API_ADMIN_EMAIL` + `ZHUCE6_SUB2API_ADMIN_PASSWORD`
+
+## 2. 核心服务与路径
+
+| 变量 | 作用 | 常见值 |
+| --- | --- | --- |
+| `ZHUCE6_HOST` | Dashboard 监听地址 | `127.0.0.1` |
+| `ZHUCE6_PORT` | Dashboard 监听端口 | `8000` |
+| `ZHUCE6_DASHBOARD_ALLOWED_ORIGINS` | 允许跨域读取 runtime/summary 的 Origin 列表 | 逗号分隔 URL |
+| `ZHUCE6_CONFIG_DIR` | 配置目录 | `<project>/config` |
+| `ZHUCE6_STATE_DIR` | 状态目录 | `<project>/state` |
+| `ZHUCE6_LOG_DIR` | 日志目录 | `<project>/logs` |
+| `ZHUCE6_POOL_DIR` | 本地账号池目录 | `<project>/pool` |
+| `ZHUCE6_CFMAIL_CONFIG_PATH` | cfmail accounts JSON | `<config>/cfmail_accounts.json` |
+| `ZHUCE6_CFMAIL_ENV_FILE` | cfmail provision env | `<config>/cfmail_provision.env` |
+
+## 3. backend 与治理任务
+
+| 变量 | 作用 | 说明 |
+| --- | --- | --- |
+| `ZHUCE6_BACKEND` | full 模式后端 | `cpa` 或 `sub2api` |
+| `ZHUCE6_CLEANUP_ENABLED` | cleanup 开关 | `true` / `false` |
+| `ZHUCE6_VALIDATE_ENABLED` | validate 开关 | `true` / `false` |
+| `ZHUCE6_ROTATE_ENABLED` | rotate 开关 | `true` / `false` |
+| `ZHUCE6_VALIDATE_SCOPE` | validate 范围 | `all` 或 `used` |
+| `ZHUCE6_ROTATE_INTERVAL` | rotate 周期秒数 | 按需调整 |
+| `ZHUCE6_ROTATE_PROBE_WORKERS` | rotate 并发 | 正整数 |
+| `ZHUCE6_ROTATE_FRESH_GRACE_SECONDS` | fresh 账号在该窗口内跳过 rotate quota probe | 默认 `600` |
+| `ZHUCE6_RESPONSES_SURVIVAL_RECENT_WINDOW_SECONDS` | responses survival 只优先 reseed 该窗口内的 recent 账号 | 默认 `1800` |
+| `ZHUCE6_RESPONSES_SURVIVAL_REQUIRE_PROVENANCE` | responses survival 是否优先要求注册 provenance | 默认 `true` |
+| `ZHUCE6_WARMUP_MIN_AGE_SECONDS` | add_phone 风险号转 warmup passed 的最小存活秒数 | 默认 `600` |
+| `ZHUCE6_WARMUP_MIN_SUCCESSFUL_PROBES` | add_phone 风险号转 warmup passed 的最小成功探测数 | 默认 `2` |
+
+### backend 运行时语义
+
+- `pool/*.json` 是持久化备份, 不是候选池.
+- backend inventory 才是运行时主池.
+- register 的成功语义等于"已经成功写入 backend 主池". 单次上游创建成功但 backend 同步失败, 记为注册失败.
+- pool 文件中的 `cpa_sync_status` 只保留为排障字段, 不再代表单独的业务阶段.
+- `validate`, `rotate`, `cleanup` 删除账号时会双删 backend + pool.
+- `rotate` 只删除 `401 invalidated`, `429 usage_limit_reached` 保留.
+- `cpa_runtime_reconcile` 负责在 backend 与 pool 漂移时做双向补齐.
+
+### CPA 变量
+
+| 变量 | 作用 |
+| --- | --- |
+| `ZHUCE6_CPA_MANAGEMENT_BASE_URL` | CPA Management API 基础地址 |
+| `ZHUCE6_CPA_MANAGEMENT_KEY` | CPA Management API Key |
+| `ZHUCE6_CPA_RUNTIME_RECONCILE_ENABLED` | 是否启用 backend 与 pool 双向 reconcile |
+| `ZHUCE6_CPA_RUNTIME_RECONCILE_COOLDOWN_SECONDS` | drift 观测 cooldown |
+| `ZHUCE6_CPA_RUNTIME_RECONCILE_RESTART_ENABLED` | 兼容保留字段, API-only 模式下不会本地重启 |
+
+### sub2api 变量
+
+| 变量 | 作用 |
+| --- | --- |
+| `ZHUCE6_SUB2API_BASE_URL` | sub2api Admin API 地址 |
+| `ZHUCE6_SUB2API_API_KEY` | API Key 认证 |
+| `ZHUCE6_SUB2API_ADMIN_EMAIL` | 管理员邮箱认证 |
+| `ZHUCE6_SUB2API_ADMIN_PASSWORD` | 管理员密码认证 |
+
+## 4. cfmail
+
+### 最小输入
+
+对于新配置, `init` 向导支持两条 cfmail 初始化路径:
+
+- 从零部署 cfmail Worker: `Cloudflare API Token + zone_name`
+- 复用已部署 cfmail Worker: `CF_AUTH_EMAIL + CF_AUTH_KEY + zone_name + worker_domain`
+
+### 自动推导结果
+
+向导会尽量自动生成:
+
+- `account_id`
+- `zone_id`
+- `ZHUCE6_D1_DATABASE_ID`
+- 在 API Token 路径下自动推导 worker domain
+- `config/cfmail_accounts.json`
+- `config/cfmail_provision.env`
+
+如果没有 API Token, 向导不会假设可以替你完成首次 Worker 部署, 而是要求显式填写一个已经可用的 `worker_domain`.
+如果复用的 `email_domain` 已经失效, 向导会在保存阶段尝试自动轮换到新的可用子域名.
+
+### 运行时必需字段
+
+| 变量 | 作用 |
+| --- | --- |
+| `ZHUCE6_CFMAIL_API_TOKEN` | Cloudflare API Token. 从零部署 cfmail Worker 时必需, `wrangler` 非交互部署也依赖它 |
+| `ZHUCE6_CFMAIL_CF_AUTH_EMAIL` | Cloudflare 认证邮箱 |
+| `ZHUCE6_CFMAIL_CF_AUTH_KEY` | Cloudflare Global API Key |
+| `ZHUCE6_CFMAIL_CF_ACCOUNT_ID` | Cloudflare Account ID |
+| `ZHUCE6_CFMAIL_CF_ZONE_ID` | Cloudflare Zone ID |
+| `ZHUCE6_CFMAIL_WORKER_NAME` | Worker 名称 |
+| `ZHUCE6_CFMAIL_ZONE_NAME` | Zone 名称 |
+
+补充:
+
+- `scripts/setup_cfmail.py` 的完整 Worker 部署链依赖 `wrangler`.
+- 在非交互环境下, `wrangler` 要求 `Cloudflare API Token`.
+- 所以只有 `CF_AUTH_EMAIL + CF_AUTH_KEY` 时, 正确用法是复用一个已部署的 `worker_domain`, 而不是期待脚本自动完成首次 Worker 部署.
+
+### 常见调优字段
+
+| 变量 | 作用 |
+| --- | --- |
+| `ZHUCE6_CFMAIL_MAIL_LIST_LIMIT` | inbox 拉取列表上限 |
+| `ZHUCE6_CFMAIL_ROTATION_WINDOW` | 域名轮换观测窗口 |
+| `ZHUCE6_CFMAIL_ROTATION_BLACKLIST_THRESHOLD` | 域名黑名单阈值 |
+| `ZHUCE6_CFMAIL_REGISTRATION_DISALLOWED_THRESHOLD` | `registration_disallowed` 快速换域阈值 |
+| `ZHUCE6_CFMAIL_ROTATION_COOLDOWN_SECONDS` | 域名轮换冷却 |
+| `ZHUCE6_CFMAIL_ADD_PHONE_THRESHOLD` | add-phone gate 阈值 |
+| `ZHUCE6_CFMAIL_WAIT_OTP_THRESHOLD` | wait-otp 阈值 |
+
+### 运行时约束
+
+- cfmail 主线默认只应保留当前 active 子域名为 enabled, 旧 auto 子域名在切换后会直接从配置中删除.
+- 当旧子域名被 OpenAI ban 后, register 线程会依赖 `CfmailProvisioner.rotate_active_domain()` 自动切换到新的 `.example.com` 子域名.
+- 若所有 enabled cfmail account 都进入 cooldown, register worker 会主动触发 rotation, 而不是一直卡死在 mailbox 阶段.
+- `CfMailMailbox` 与 register loop 共享同一套 `CfmailAccountManager` cooldown 视图, 因此 mailbox 侧 cooldown 与 rotation 检测必须保持同一配置文件.
+- `ZHUCE6_D1_DATABASE_ID` 不再有 repo 内默认 UUID. 新环境必须由 `init` 自动写入或手工配置; 若为空, `d1_cleanup` 会直接跳过.
+
+## 5. 注册线程与代理池
+
+| 变量 | 作用 | 常见值 | 约束 |
+| --- | --- | --- | --- |
+| `ZHUCE6_REGISTER_THREADS` | 注册并发线程数 | `12` | **不得大于代理池大小**, 否则多余线程永远拿不到代理 |
+| `ZHUCE6_REGISTER_TARGET_COUNT` | 注册目标数 | `0` (无限) | 达到后自动停止 |
+| `ZHUCE6_REGISTER_SLEEP_MIN` | 注册间隔下限 (秒) | `3` | - |
+| `ZHUCE6_REGISTER_SLEEP_MAX` | 注册间隔上限 (秒) | `10` | - |
+| `ZHUCE6_REGISTER_MAX_CONSECUTIVE_FAILURES` | 连续失败上限 | `3` | 超过后线程暂停 |
+
+### add_phone 与 token 恢复调优
+
+| 变量 | 作用 | 默认语义 |
+| --- | --- | --- |
+| `ZHUCE6_ADD_PHONE_OAUTH_MAX_ATTEMPTS` | add_phone 后 fresh login fallback 的最大尝试次数 | `2`, 范围 `1..3` |
+| `ZHUCE6_ADD_PHONE_OAUTH_OTP_TIMEOUT_SECONDS` | add_phone fallback 登录链里的 OTP 等待上限 | 默认 `90`, 范围 `30..180` |
+| `ZHUCE6_POST_CREATE_LOGIN_DELAY_SECONDS` | `create_account` 后进入 fresh login fallback 前的等待秒数 | 默认 `8`, 范围 `0..600` |
+| `ZHUCE6_PENDING_TOKEN_RETRY_DELAY_SECONDS` | add_phone deferred retry 的基础延迟 | 当前实现会把首轮基础延迟钳到 `60s`, 避免把 token 恢复推到 5 分钟观测窗口之外 |
+
+运行时要点:
+
+- 如果 `create_account` 已直接返回 `https://chatgpt.com/api/auth/callback/openai?...`, 主流程会先走 `callback/openai -> /api/auth/session` 直取 token, 跳过 workspace flow 与 fresh login.
+- `create_account` 命中 `add_phone` 不等于账号一定废掉.
+- 主流程会先尝试 direct session token 提取, 失败后才回退 fresh login.
+- 如果当次线程仍拿不到 token, 账号会带着凭据进入 pending retry queue, 由后台补取 token.
+- Dashboard 总览中的"成功"已经是 backend 入池成功后的累计值, 不再单独区分 CPA sync.
+
+### 代理池
+
+| 变量 | 作用 | 常见值 |
+| --- | --- | --- |
+| `ZHUCE6_REGISTER_PROXY` | 注册链主代理 | 单个 URL, 启用代理池时留空 |
+| `ZHUCE6_REGISTER_FRESH_PROXY_REGIONS` | fresh 注册优先代理地区 | `tw,jp,hk,us` |
+| `ZHUCE6_ENABLE_PROXY_POOL` | 是否启用代理池 | `1` / `0` |
+| `ZHUCE6_PROXY_POOL_SIZE` | 代理池节点数 | `12` |
+| `ZHUCE6_PROXY_POOL_DIRECT_URLS` | 直接代理列表 | 分号分隔 |
+| `ZHUCE6_PROXY_POOL_CONFIG` | Clash YAML 路径 | 文件路径 |
+| `ZHUCE6_PROXY_POOL_REGIONS` | 优先地区 | `tw,jp,hk,us` |
+
+> **重要**: `ZHUCE6_REGISTER_THREADS` 必须 <= `ZHUCE6_PROXY_POOL_SIZE`. 代理池每个节点同一时间只服务一个线程, 多余线程会因 `no proxy available in pool` 持续失败.
+

+## 5.1 cfmail 多活动域与轮换
+
+| 变量 | 作用 | 常见值 |
+| --- | --- | --- |
+| `ZHUCE6_CFMAIL_ROTATION_WINDOW` | 域名轮换观测窗口 | - |
+| `ZHUCE6_CFMAIL_ROTATION_BLACKLIST_THRESHOLD` | 域名黑名单阈值 | - |
+| `ZHUCE6_CFMAIL_REGISTRATION_DISALLOWED_THRESHOLD` | `registration_disallowed` 快速换域阈值 | `2` |
+| `ZHUCE6_CFMAIL_ROTATION_COOLDOWN_SECONDS` | 域名轮换冷却 | - |
+| `ZHUCE6_CFMAIL_MAILBOX_REUSED_THRESHOLD` | `user_already_exists` 域级 stoploss 阈值 | `2` |
+| `ZHUCE6_CFMAIL_ACTIVE_DOMAIN_COUNT` | 目标活动域数量 | `3` |
+| `ZHUCE6_CFMAIL_START_INTERVAL_SECONDS` | 单域启动节流 | `8` |
+| `ZHUCE6_CFMAIL_MAX_INFLIGHT` | 单域最大并发 inflight | `4` |
+| `ZHUCE6_CFMAIL_FRESH_DOMAIN_ATTEMPT_BUDGET` | 新域完成尝试预算 | `2` |
+| `ZHUCE6_CFMAIL_ADD_PHONE_WINDOW` | add_phone 域级观测窗口 | `10` |
+| `ZHUCE6_CFMAIL_ADD_PHONE_THRESHOLD` | add_phone 域级 stoploss 阈值 | `3` |
+| `ZHUCE6_CFMAIL_WAIT_OTP_WINDOW` | wait_otp 域级观测窗口 | `6` |
+| `ZHUCE6_CFMAIL_WAIT_OTP_THRESHOLD` | wait_otp 域级 stoploss 阈值 | `2` |
+
+运行时要点:
+
+- 当前主线是多活动域池, 不再依赖单域 canary 探路.
+- worker 会在活动域池中选择可用域, 每个域各自维护 inflight 与 start interval.
+- `mailbox_reused`, `add_phone_gate`, `wait_otp` 都按域计数, 命中阈值后仅摘除该域, 后台异步补位.
+- `cleanup_stale_domains` 只会清理已退役的 `auto*.zone` 历史域名, 不会把整个活动域池压回单域.
+
+> **注意**: stale cleanup 是 best-effort. 如果 Cloudflare 返回 DNS read-only / code `1043`, 实现会跳过该旧记录, 不应因为旧资源删除失败而回滚已经完成的新域名切换.
+
+### 轮换主链
+
+`CfmailProvisioner.rotate_active_domain()` 的成功判定以新域名主链为准:
+
+1. 创建 email routing rule
+2. 创建 DNS 记录
+3. 更新 worker domain bindings
+4. smoke test
+5. 切换 active domain
+6. best-effort cleanup old auto-domain artifacts
+
+因此排障时, 应优先关注 `success` / `new_domain` 与 `config/cfmail_accounts.json` 中的 active 域名是否变化, 而不是把 cleanup 告警误判为 rotation 失败.
+
+## 6. 平台差异
+
+### Windows
+
+- 推荐 PowerShell 7.
+- `doctor --fix` 会自动处理 Python 依赖与 worker npm 依赖.
+- `git`, `node`, `npx` 仍需你自行安装.
+
+### Linux / WSL
+
+- 命令与 README 主线一致.
+- 如果使用 Clash YAML, 还需要系统里可用的 `sslocal`.
+- 手工部署 cfmail worker 时优先使用 `npx wrangler`.

+# Pool 文件格式
+
+zhuce6 注册成功的账号保存在 `pool/` 目录, 每个账号一个 JSON 文件. 当前仓库的稳定口径是:
+
+- `pool/*.json` 是持久化备份层
+- CPA / sub2api 后端是运行时主池
+- register 成功后先写 `pool`, 再立即同步到后端
+- rotate / validate / cleanup 删除时始终双删 backend + pool
+- backend 库存与本地备份发生漂移时, 会做双向 reconcile
+
+文件名生成逻辑见 `platforms/chatgpt/pool.py` 的 `build_pool_filename`.
+
+## 文件命名
+
+`<email>.json`, 例如 `user123@mail.example.com.json`.
+
+当 `email` 缺失时, 会回退为 `<account_id>.json` 或 `chatgpt_<timestamp>.json`.
+
+## 字段说明
+
+以下字段来自实际写盘逻辑 `platforms/chatgpt/pool.py` 与 CPA 上传逻辑 `platforms/chatgpt/cpa_upload.py`.
+
+| 字段 | 类型 | 必须 | 说明 |
+|------|------|------|------|
+| email | string | ✅ | 注册邮箱, 同时用于文件名 |
+| password | string | 通常有 | 注册密码 |
+| access_token | string | ✅ | ChatGPT access token |
+| refresh_token | string | 常见 | 用于刷新 access_token |
+| account_id | string | 常见 | OpenAI 账号 ID |
+| workspace_id | string | 常见 | Workspace ID |
+| id_token | string | 可选 | 登录链返回的 ID token |
+| session_token | string | 可选 | 会话 token |
+| source | string | ✅ | 来源, 默认 `register` |
+| health_status | string | ✅ | 最近一次健康标记, 默认 `unknown` |
+| created_at | string (ISO 8601) | ✅ | 本地 pool 文件创建时间 |
+| backup_written | boolean | ✅ | 本地持久化备份是否已写入, 默认 `true` |
+| cpa_sync_status | string | ✅ | 最近一次 backend 同步状态, `pending` / `synced` / `failed` |
+| last_cpa_sync_at | string | ✅ | 最近一次 backend 同步时间 |
+| last_cpa_sync_error | string | ✅ | 最近一次 backend 同步失败信息 |
+| last_probe_at | string | ✅ | 最近一次探测时间 |
+| last_probe_status_code | integer or null | ✅ | 最近一次探测 HTTP 状态码 |
+| last_probe_result | string | ✅ | 最近一次探测结果摘要 |
+| last_probe_detail | string | ✅ | 最近一次探测详细信息 |

+  "last_probe_result": "",
+  "last_probe_detail": ""
+}
+```
+
+## 对接说明
+
+### 对接 CPA
+
+如果你走的是 CPA Management API, register 成功后会直接同步到 CPA. 当 CPA 容器重启导致库存丢失时, runtime reconcile 会从 `pool/*.json` 回灌缺失账号.
+
+### 对接 sub2api
+
+如果你走的是 `backend=sub2api`, 应按 sub2api Admin API 的上传接口对接.
+
+### 自定义对接
+
+`pool/*.json` 是标准 JSON, 可以用任何语言解析.
+
+关键字段:
+
+- `refresh_token`: 长期访问与续期最关键的字段.
+- `access_token`: 短期访问 token, 一般有效期较短.
+- `backup_written`: 当前本地持久化备份是否有效.
+- `cpa_sync_status`: backend 是否已经与本地备份完成同步.

+# zhuce6 Troubleshooting
+
+先记住主线:
+
+```bash
+uv run python main.py init
+uv run python main.py doctor --fix
+uv run python main.py --mode lite
+# 或
+uv run python main.py --mode full
+```
+
+如果排障前还没跑 `doctor --fix`, 先跑它.
+
+## 1. 基础检查
+
+```bash
+uv run python main.py status
+uv run python main.py doctor --fix
+```
+
+启动后再看 API:
+
+```bash
+export ZHUCE6_BASE_URL="http://<dashboard-host>:<dashboard-port>"
+curl -sS "$ZHUCE6_BASE_URL/api/runtime" | python3 -m json.tool | head -n 80
+curl -sS "$ZHUCE6_BASE_URL/api/health/dependencies" | python3 -m json.tool | head -n 80
+```
+
+## 2. `init` 之后仍然跑不起来
+
+优先检查:
+
+- `.env` 是否是本次向导写入的目标文件
+- `doctor --fix` 是否已执行
+- 当前启动命令是否显式带了 `--mode lite` 或 `--mode full`
+- `backend` 是否与你填写的后端配置一致
+
+## 3. cfmail 不可用
+
+### 新配置路径
+
+现在新配置支持两条 cfmail 初始化路径:
+
+- 从零部署 cfmail Worker: `Cloudflare API Token + zone_name`
+- 复用已部署 cfmail Worker: `CF_AUTH_EMAIL + CF_AUTH_KEY + zone_name + worker_domain`
+
+如果向导已经跑过, 先检查这些结果是否存在:
+
+- `config/cfmail_accounts.json`
+- `config/cfmail_provision.env`
+- `.env` 中的:
+  - `ZHUCE6_CFMAIL_API_TOKEN`
+  - `ZHUCE6_CFMAIL_CF_AUTH_EMAIL`
+  - `ZHUCE6_CFMAIL_CF_AUTH_KEY`
+  - `ZHUCE6_CFMAIL_CF_ACCOUNT_ID`
+  - `ZHUCE6_CFMAIL_CF_ZONE_ID`
+  - `ZHUCE6_CFMAIL_WORKER_NAME`
+  - `ZHUCE6_CFMAIL_ZONE_NAME`
+
+### 已有配置路径
+
+如果仓库内已有 cfmail 配置, `init` 默认会提示复用. 若你误选了重新生成, 应先对照现有 `config/` 内容确认是否与 live 配置一致.
+
+### 仍需手工排查时
+
+```bash
+uv run python scripts/setup_cfmail.py --help
+```
+
+注意:
+
+- `scripts/setup_cfmail.py` 的完整部署链依赖 `wrangler`.
+- `wrangler` 在非交互环境下要求 `Cloudflare API Token`.
+- 所以如果你只有 `CF_AUTH_EMAIL + CF_AUTH_KEY`, 不要指望它完成首次 Worker 部署, 应该在 `init` 时直接填写已部署的 `worker_domain`.
+- 只有需要从零部署 Worker 时, 才应走 `uv run python scripts/setup_cfmail.py --api-token <token> --zone-name <zone>` 这条路径.
+- 如果你填入的 `email_domain` 已经失效, `init` 在保存阶段会尝试自动轮换到新的可用子域名. 若仍失败, 再手工检查 DNS 与 Email Routing.
+
+## 4. `doctor --fix` 之后还有依赖问题
+
+`doctor --fix` 当前会自动处理:
+
+- `uv sync`
+- cfmail worker 目录下的 `npm install --no-fund --no-audit`
+
+它不会替你全局安装:
+
+- `git`
+- `node`
+- `npm`
+- `npx`
+- `sslocal`
+
+所以如果报告里仍有失败项, 直接按报告补齐系统依赖即可.
+
+如果 `d1_cleanup` 一直跳过, 再检查:
+
+- `ZHUCE6_D1_DATABASE_ID` 是否为空
+- 该值是否由 `init` / cfmail 向导自动写入
+
+## 5. 代理问题
+
+### 直接代理 URL
+
+优先检查:
+
+- `ZHUCE6_REGISTER_PROXY`
+- `ZHUCE6_PROXY_POOL_DIRECT_URLS`
+
+### Clash YAML
+
+如果你选择 Clash YAML 模式, 还要确认:
+
+```bash
+command -v sslocal || command -v ss-local || true
+```
+
+如果没有 `sslocal`, 先安装它, 再重新执行:
+
+```bash
+uv run python main.py doctor --fix
+```
+
+## 6. `full + cpa` 不可用
+
+重点检查:
+
+- `ZHUCE6_BACKEND=cpa`
+- `ZHUCE6_CPA_MANAGEMENT_BASE_URL`
+- `ZHUCE6_CPA_MANAGEMENT_KEY`
+
+然后看:
+
+```bash
+curl -sS "$ZHUCE6_BASE_URL/api/health/dependencies" | python3 -m json.tool | head -n 80
+```
+
+## 7. `full + sub2api` 不可用
+
+重点检查:
+
+- `ZHUCE6_BACKEND=sub2api`
+- `ZHUCE6_SUB2API_BASE_URL`
+- 认证是否完整:
+  - `ZHUCE6_SUB2API_API_KEY`
+  - 或 `ZHUCE6_SUB2API_ADMIN_EMAIL` + `ZHUCE6_SUB2API_ADMIN_PASSWORD`
+
+`doctor` 与 `/api/health/dependencies` 都会明确显示 sub2api ready / unavailable.
+
+## 8. Dashboard 正常, 但没有注册任务
+
+先看 `/api/runtime`:
+
+- `runtime_mode`
+- `registered_tasks`
+- `register_enabled`
+
+常见原因:
+
+- 当前模式是 `dashboard`
+- `ZHUCE6_REGISTER_ENABLED=false`
+- `cfmail` 运行时变量不完整
+- 代理未配置或不可达
+
+## 9. Windows / Linux / WSL
+
+### Windows
+
+- 推荐 PowerShell 7.
+- 先保证 `python`, `uv`, `node`, `npm`, `npx`, `git` 可用.
+- 直接按 README 主线运行即可.
+
+### Linux
+
+- 按 README 主线运行.
+- 需要 Clash YAML 时, 记得额外准备 `sslocal`.
+
+### WSL
+
+- 与 Linux 路径一致.
+- 推荐依赖与仓库都放在 WSL 内执行.
+
+如果你需要从别的前端域读取 `/api/runtime` 或 `/api/summary`, 还要配置:
+
+- `ZHUCE6_DASHBOARD_ALLOWED_ORIGINS=http://your-dashboard.example.com`
+
+## 10. cfmail OTP 收不到 / 全部 wait_otp 超时
+
+### 现象
+
+注册日志所有线程卡在 `wait_otp`, 180s 超时:
+
+```
+[zhuce6:register] [thread-1] ❌ failed [stage=wait_otp]: otp retrieval failed
+  ↳ verification code timed out after 181.88s
+  ↳ otp mailbox diagnostics: polls=45 scanned=0
+```
+
+### 根因
+
+cfmail 子域名的 DNS 记录 (MX + SPF) 缺失. 没有 MX 记录, Cloudflare 无法接收邮件, OTP 永远到不了.
+
+### 诊断
+
+```bash
+source config/cfmail_provision.env
+
+# 检查子域名 DNS 记录数量 (应 >= 4: 3xMX + 1xTXT)
+curl -s "https://api.cloudflare.com/client/v4/zones/$ZHUCE6_CFMAIL_CF_ZONE_ID/dns_records?name=<subdomain>.example.com" \
+  -H "X-Auth-Email: $ZHUCE6_CFMAIL_CF_AUTH_EMAIL" \
+  -H "X-Auth-Key: $ZHUCE6_CFMAIL_CF_AUTH_KEY" \
+  | python3 -c "import sys,json; r=json.load(sys.stdin); print(f'records: {r[\"result_info\"][\"total_count\"]}')"
+```
+
+### 修复
+
+```bash
+source config/cfmail_provision.env
+uv run python -c "
+from core.cfmail_provisioner import CfmailProvisioner
+p = CfmailProvisioner()
+for acct in p._load_all_accounts():
+    if not acct.get('enabled'): continue
+    domain = acct['email_domain']
+    label = acct['name'].replace('cfmail-', '')
+    try:
+        p._create_email_routing_rule(domain, label)
+        p._create_dns_records(domain)
+        p._update_worker_domains(domain)
+        print(f'fixed {domain}')
+    except Exception as e:
+        print(f'error {domain}: {e}')
+"
+```
+
+## 11. no proxy available in pool
+
+### 现象
+
+```
+[zhuce6:register] [thread-13] ❌ exception: no proxy available in pool
+```
+
+### 根因
+
+`ZHUCE6_REGISTER_THREADS` 大于 `ZHUCE6_PROXY_POOL_SIZE`. 多余线程拿不到代理.
+
+### 修复
+
+确保线程数 <= 代理池大小:
+
+```bash
+# .env
+ZHUCE6_REGISTER_THREADS=12
+ZHUCE6_PROXY_POOL_SIZE=12
+```
+
+## 12. sslocal 残留进程堆积
+
+### 现象
+
+## 13. fresh 号刚注册就很快 `401 no_organization`
+
+先看 `/api/account-survival` 或 `state/responses_survival_tracker.json`:
+
+- `first_invalid_error_code`
+- `registration_proxy_region`
+- `registration_post_create_gate`
+- `first_use_proxy_key`
+- `first_use_proxy_region`
+- `fingerprint_consistent`
+
+当前优先排查顺序:
+
+1. fresh 注册是否落到 `us`
+2. 首用 probe 是否复用了注册代理
+3. 该号是否 `registration_post_create_gate = add_phone`
+
+如果 fresh 号主要出现在 `us`, 先把:
+
+```bash
+ZHUCE6_REGISTER_FRESH_PROXY_REGIONS=tw,jp,hk,us
+```
+
+如果 live 日志里连续出现 `registration_disallowed`, 说明当前活动域已经被上游集中拒绝. 这时不要继续等满整个黑名单窗口, 应确认:
+
+```bash
+ZHUCE6_CFMAIL_REGISTRATION_DISALLOWED_THRESHOLD=2
+```
+
+这样同域连续 2 次 `registration_disallowed` 就会直接退域补位.
+
+并重启 runtime.
+
+## 14. survival 实验里混入很多旧号
+
+如果 cohort 里大多数账号没有:
+
+- `registration_fingerprint_profile`
+- `registration_proxy_region`
+
+说明 reseed 仍在吃旧历史号, 这会污染实验.
+
+优先检查:
+
+```bash
+grep -n "ZHUCE6_RESPONSES_SURVIVAL" .env
+```
+
+建议:
+
+```bash
+ZHUCE6_RESPONSES_SURVIVAL_REQUIRE_PROVENANCE=true
+ZHUCE6_RESPONSES_SURVIVAL_RECENT_WINDOW_SECONDS=1800
+```
+
+## 15. add_phone 成功号看起来能用, 但很快死
+
+这类号现在不会走旧候选池, 但会在单池里带 warmup 风险字段:
+
+- `warmup_required=true`
+- `warmup_state=pending|passed|failed`
+
+判断方法:
+
+- `pending`: 还在观察窗口内
+- `passed`: 已满足最小成功探测数或最小存活时间
+- `failed`: 首次 invalid 发生在 warmup 期间
+
+如果这类号比例过高, 不要先怀疑 dashboard, 先看:
+
+- 注册代理区域
+- `first_invalid_error_code`
+- `first_invalid_proxy_region`
+
+每次启动注册机生成 12 个 sslocal, 但停止时不清理. 长期积累后系统有上百个 sslocal 进程.
+
+### 修复
+
+重启前先清理:
+
+```bash
+pkill -f sslocal
+```
+
+## 13. `create_account` 已 200, 但 5 分钟 success 看起来是 0 / 全是 `add_phone_gate`
+
+### 现象
+
+- `logs/register.log` 里能看到 `create_account status: 200`
+- 线程最终却频繁报:
+
+```text
+[zhuce6:register] [thread-1] ❌ failed [stage=add_phone_gate]: post-create flow requires phone gate
+```
+
+- 同时日志里还能看到:
+
+```text
+📥 deferred token retry enqueued
+```
+
+### 根因
+
+这通常不是 `create_account` 本身失败, 而是 add_phone 后的 token 恢复链被拖慢或被误判:
+
+- 账号创建已经成功, 但 direct session token / fresh login fallback 当次没有拿到 token.
+- 账号被放进 pending retry queue 后, 如果首次重试发生得太晚, 5 分钟窗口里就会看起来像 `0%`.
+
+当前实现已经做了两层处理:
+
+1. 如果 `create_account` 已直接返回 `https://chatgpt.com/api/auth/callback/openai?...`, 先走 `callback/openai -> /api/auth/session` 直取 token.
+2. `create_account` 命中 add_phone 后, 再尝试 direct session token 提取.
+3. 如果当次线程仍未拿到 token, pending retry queue 会在短窗口内补取, 首轮基础延迟会钳到 `60s`.
+
+### 先确认
+
+优先同时看两类日志:
+
+```bash
+grep -n "add_phone_gate\\|deferred token retry enqueued\\|deferred token acquired\\|direct session token" logs/register.log | tail -n 80
+```
+
+如果你能看到:
+
+- `post-create add_phone: attempting direct session token extraction`
+- `📥 deferred token retry enqueued`
+- `[pending] ✅ deferred token acquired`
+
+说明问题在 token 恢复时序, 不是 `create_account` 没成功.
+
+### 结论判断
+
+- 只有 `add_phone_gate`, 没有任何 `[pending]` 成功: 再检查代码是否已包含 direct session token 路径与 60s pending retry 限制.
+- 有 `[pending] ✅ deferred token acquired`: 说明账号并非 0 成功, 只是不能只按线程即时结果统计.
+- 如果你在排查旧版本, 还要确认它是否在 `create_account` 后直接丢掉了 callback/session 结果, 又重新触发 fresh login, 这会显著提高 add_phone 命中率.
+
+## 14. cfmail 全部报 `account unavailable` / mailbox 阶段持续失败
+
+### 现象
+
+注册日志持续出现:
+
+```text
+[zhuce6:register] [thread-1] ❌ failed [stage=mailbox]: cfmail account unavailable, current accounts: 无
+```
+
+或者线程长时间停在 mailbox 失败, 没有新的 cfmail 子域名被切出.
+
+### 根因
+
+这是 cfmail 全域 cooldown 场景:
+
+- 当前 enabled 的 cfmail 账户全部进入 `CfmailAccountManager` cooldown.
+- `select_account()` 返回 `None`, register 在 mailbox 阶段直接失败.
+- 这类失败没有走到 OpenAI `unsupported_email` / `registration_disallowed` 信号时, 不会靠黑名单窗口自然触发 rotation.
+
+当前实现已经在 register worker 顶部检测这个状态, 一旦发现所有 cfmail account 都不可选, 会主动调用 `CfmailProvisioner.rotate_active_domain()` 打破死锁.
+
+### 先确认
+
+看 `logs/register.log` 是否出现:
+
+```text
+[cfmail] all accounts in cooldown, forcing domain rotation to break deadlock
+```
+
+如果有, 说明死锁检测已经触发, 接着只需要看 rotation 是否成功.
+
+### 手工验证 rotation
+
+```bash
+set -a && source .env && set +a
+PYTHONPATH=. uv run python -c "
+from core.cfmail_provisioner import CfmailProvisioner
+p = CfmailProvisioner()
+result = p.rotate_active_domain()
+print(f'success={result.success}, new={result.new_domain}, error={result.error}')
+"
+```
+
+如果这里成功, 但 register 仍不恢复, 再检查:
+
+- `config/cfmail_accounts.json` 中是否已有新的 enabled 子域名
+- worker domain 是否仍可访问
+- 新子域名的 DNS / routing rule 是否已创建
+
+## 15. `rotate_active_domain()` 因 DNS read-only / code 1043 报错
+
+### 现象
+
+手工调用或自动 rotation 时, 日志出现类似:
+
+```text
+HTTP 400 {"errors":[{"code":1043,"message":"DNS record is read only"}]}
+```
+
+### 根因
+
+Cloudflare 某些历史 DNS record 或 email routing rule 可能是只读或受保护资源. 这些资源常出现在旧 auto 域名被切换后的残留清理阶段.
+
+当前实现里:
+
+- `_delete_domain_artifacts()` 对删除失败按 best-effort 处理
+- `cleanup_stale_domains()` 会跳过 read-only DNS / routing rule
+- `rotate_active_domain()` 在新域名已经完成 DNS + routing + worker binding + smoke test 后, 即使 cleanup 失败也不会回滚整个 rotation
+
+所以 `1043` 更应被视为旧资源清理告警, 而不是新域名切换失败.
+
+### 手工验证
+
+如果怀疑 rotation 没真正切过去, 重点看最终结果而不是 cleanup 告警:
+
+```bash
+set -a && source .env && set +a
+PYTHONPATH=. uv run python -c "
+from core.cfmail_provisioner import CfmailProvisioner
+p = CfmailProvisioner()
+result = p.rotate_active_domain()
+print(result)
+"
+```
+
+只要输出里 `success=True`, 并且 `new_domain` 已变更, 就说明 rotation 主链成功.
+
+## 16. CPA 里账号突然变少 / 重启后 inventory 丢失
+
+### 现象
+
+- CPA `auth-files` 数量明显小于本地 `pool/*.json`
+- CPA 重启后 Dashboard 里的 `cpa_count` 突然下降
+- 注册虽然还在成功, 但旧账号像是消失了
+
+### 正确理解
+
+当前稳定结构不是“本地 pool 单池”, 而是:
+
+- `pool/*.json`: 持久化备份
+- CPA backend: 运行时主池
+
+因此 CPA 丢库存时, 正确修复动作不是重新解释成双池晋升, 而是做 backup reconcile.
+
+### 已有机制
+
+- register 启动时会先做一次 runtime reconcile
+- `rotate` 周期任务也会检测 drift
+- 若 backend 缺账号, 会从 `pool/*.json` 回灌到 CPA
+- 若 backend 有账号但本地没有备份, 会反向补写 pool
+
+### 先确认
+
+```bash
+uv run python main.py status
+curl -sS "$ZHUCE6_BASE_URL/api/summary" | python3 -m json.tool | head -n 80
+```
+
+重点看:
+
+- `pool_count`
+- `cpa_count`
+- register 概览里的 `total_attempts` / `total_success`
+- `pool/cpa_runtime_reconcile_state.json`
+
+### 结论判断
+
+- 若 `pool_count` 明显大于 `cpa_count`, 优先看 reconcile 是否正在补回.
+- 若 `total_attempts` 持续增长但 `total_success` 不动, 且失败热点出现 `cpa_sync_failed`, 说明 register 新号写 backend 失败, 应先排查 CPA Management API 或网络错误.
+
+## 17. validate 删除了 backend, 但本地 pool 还残留
+
+当前实现中, `validate`, `rotate`, `cleanup` 都应双删 backend + pool.
+
+如果你仍看到“backend 已删但 pool 还在”的残留, 先确认代码是否为最新版本, 再复查对应任务日志:
+
+- `validate`: `deleted`
+- `rotate`: `deleted_401`
+- `cleanup`: `deleted`
+
+## 18. hard add_phone 为什么始终没有 workspace / org
+
+### 现象
+
+- `create_account` 已 200, 但后续一直停在:
+
+```text
+https://auth.openai.com/add-phone
+```
+
+- 日志里反复出现:
+
+```text
+workspace list missing in auth session payload
+solution D: no accessToken in session response, keys=['WARNING_BANNER']
+```
+
+- fresh login fallback 做完后, 仍然没有:
+  - callback url
+  - session token
+  - workspace select
+  - organization select
+
+### 当前已确认的根因
+
+这类 hard add_phone 已被 live 证实为服务端会话状态问题, 不是本地漏流程:
+
+1. `oai-client-auth-session` 里没有 `workspaces`.
+2. `https://auth.openai.com/api/accounts/client_auth_session_dump` 已经可打通, 但返回仍然是:
+   - `status = 200`
+   - `workspace_count = 0`
+3. `/api/auth/session` 仍然只返回:
+   - `WARNING_BANNER`
+   - 没有 `accessToken`
+
+这说明:
+- 当前 hard add_phone 的 full client auth session 本身不包含 `workspaces` / `orgs`.
+- 客户端因此没有可继续到 workspace / organization route 的材料.
+
+### 先确认
+
+优先看 live register 日志:
+
+```bash
+grep -n "client auth session dump\\|workspace list missing\\|WARNING_BANNER\\|add-phone trace saved" /home/sophomores/zhuce6/logs/main_full_4threads_*.log | tail -n 80
+```
+
+若能同时看到:
+
+- `client auth session dump status: 200`
+- `client auth session dump workspace count: 0`
+- `workspace list missing in auth session payload`
+- `solution D: no accessToken in session response, keys=['WARNING_BANNER']`
+
+就说明当前不是本地漏掉 workspace route, 而是服务端会话本身没有给 workspace / org.
+
+### 结论判断
+
+- 如果 `client_auth_session_dump` 已经是 200, 但 `workspace_count` 仍为 0:
+  - 不要再把问题归因到 cookie 解析或 workspace select 漏调用.
+- 如果 add-phone trace 里:
+  - `auth_session_workspace_count = 0`
+  - `auth_session_dump_workspace_count = 0`
+  - `direct_session_keys = ["WARNING_BANNER"]`
+  - latest fresh login 仍停在 `/add-phone`
+  说明这就是 server-side gate.
+
+### 当前可做与不可做
+
+- 可以做:
+  - 继续保留 trace artifact 与吞吐优化.
+  - 对 hopeless hard add_phone 提前 short-circuit 到 deferred retry.
+- 不要做:
+  - 在没有新 live 证据前, 继续假设客户端还存在隐藏 continue path.
+  - 把这个问题当成"再多做一次 fresh login 也许就能过".

+# Multi-Active-Domain Registration Throughput Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Replace single-active-domain cfmail registration with multi-active-domain scheduling so throughput scales with threads while preserving CPA-backed success semantics.
+
+**Architecture:** Refactor cfmail provisioning from single-domain rotation to an active-domain pool manager, route each worker through an explicit domain-selection channel, delete canary gating, and apply per-domain inflight/start-interval + per-domain stoploss. Keep pending token retry as a recovery sidecar, not a scheduler gate. Update dashboard/runtime APIs to expose per-domain health and throughput.
+
+**Tech Stack:** Python 3.11, FastAPI, uv, pytest, cfmail provisioner, CPA HTTP backend.

+# Account Survival Upgrade Implementation Plan
+
+## 结论
+
+当前阶段不再把问题定义成"继续扩大指纹池".  
+最新实验已经证明:
+
+1. 注册与 probe 的 UA 指纹不一致, 确实是问题, 但已经修正.
+2. 即使 `fingerprint_consistent = true`, fresh 号仍可能在几十秒内 `401 no_organization`.
+3. 当前更强的根因是:
+   - fresh 注册出口节点质量
+   - 首用 probe 没有绑定注册代理
+   - `add_phone` 成功号质量显著更差
+   - 实验 cohort 混入旧号, 导致判断失真
+
+因此, 本计划调整为**先修 fresh 首用与实验卫生, 再做长期评分与健康状态机**.
+
+---
+
+## 0. 约束与非目标
+
+### 必须保持
+
+- 保持当前主线:
+  - 单池 + backend API
+  - `main.py` 统一入口
+  - `lite + cfmail + register`
+  - `full + cpa`
+  - `full + sub2api`
+- 保持当前 cfmail 多活动域 runtime 语义.
+- 保持当前 add_phone token 恢复链:
+  - direct session token
+  - workspace flow
+  - fresh login fallback
+  - pending retry sidecar
+- 不恢复旧候选池 / 晋升池 / 两阶段池叙事.
+
+### 这轮明确不做
+
+- 不做浏览器自动化重写.
+- 不做无限随机指纹.
+- 不把 add_phone 成功号直接改成另一套后端主线.
+- 不承诺"代码改了就一定长寿", 必须靠实验验证.
+
+---
+
+## 1. 当前阶段目标
+
+### G1. 修正 fresh 实验样本质量
+
+- `responses_survival` 只优先追踪带注册 provenance 的 recent accounts.
+- 减少旧号污染 cohort.
+
+### G2. 让首用尽量复用注册代理语义
+
+- 首次 `responses` 探测优先复用:
+  - `registration_proxy_key`
+  - 不可用时至少复用 `registration_proxy_region`
+
+### G3. 收紧 fresh 注册节点
+
+- fresh 注册优先只走 `tw,sg`.
+- 不再让 `us` 自然落入 fresh 主路径.
+
+### G4. 显式标记 add_phone 风险
+
+- 单池内新增 warmup 风险字段, 但不恢复候选池.
+- add_phone 成功号进入 `warmup_required` 状态.
+- survival probe 负责把它更新为:
+  - `pending`
+  - `passed`
+  - `failed`
+
+### G5. 为下一阶段打基础
+
+这轮完成后, 再决定是否进入:
+- cfmail domain score
+- account health state machine
+- bounded fingerprint profile pool
+
+---
+
+## 2. 实现顺序
+
+### Task 1. Fresh 实验卫生
+
+目标:
+- `responses_survival` reseed 时优先选择:
+  - recent accounts
+  - 带 `registration_fingerprint_profile` 的号
+
+文件:
+- `ops/responses_survival.py`
+- `core/settings.py`
+- `scripts/run_responses_survival.py`
+- 对应 pytest
+
+验收:
+- cohort 优先由新日志时代的 fresh 号组成
+- 旧号只在无 fresh provenance 样本时才补位或被跳过
+
+### Task 2. 首用绑定注册代理
+
+目标:
+- probe 时优先复用 `registration_proxy_key`
+- 不可直接命中时, 至少按 `registration_proxy_region` 选代理
+
+文件:
+- `core/proxy_pool.py`
+- `ops/responses_survival.py`
+- 对应 pytest
+
+验收:
+- survival probe 对带 provenance 的账号能记录:
+  - `first_use_proxy_key`
+  - `first_use_proxy_region`
+  - `first_invalid_proxy_key`
+  - `first_invalid_proxy_region`
+
+### Task 3. Fresh 注册区域收敛
+
+目标:
+- fresh 注册 worker 从代理池取节点时, 默认优先 `tw,sg`
+
+文件:
+- `core/settings.py`
+- `core/registration.py`
+- 对应 pytest
+
+验收:
+- register worker 从 proxy pool `acquire()` 时传入 fresh 区域偏好
+- 设置缺失时安全回退当前行为
+
+### Task 4. Add-phone warmup 风险标记
+
+目标:
+- 单池内显式标记 add_phone 成功号风险, 但不改变单池主线
+
+文件:
+- `platforms/chatgpt/pool.py`
+- `ops/responses_survival.py`
+- `dashboard/api.py`
+- 对应 pytest
+
+字段:
+- `warmup_required`
+- `warmup_state`
+- `warmup_passed`
+- `warmup_completed_at`
+- `successful_probe_count`
+
+状态:
+- `not_required`
+- `pending`
+- `passed`
+- `failed`
+
+验收:
+- add_phone 成功号默认 `warmup_required = true`
+- survival 连续成功后可转 `passed`
+- 首次 invalid 时可转 `failed`
+
+### Task 5. 文档与可观测性
+
+目标:
+- 把新设置与新诊断口径写进稳定文档
+
+文件:
+- `docs/CONFIG_REFERENCE.md`
+- `docs/TROUBLESHOOTING.md`
+
+---
+
+## 3. 这轮不做的任务
+
+以下内容保留为下一阶段候选, 本计划不直接实现:
+
+1. `core/cfmail_domain_score.py`
+2. `ops/account_health.py`
+3. bounded fingerprint profile pool
+4. dashboard 大改版
+
+原因:
+- 当前最强根因不在这三块.
+- 必须先用更干净的 fresh cohort 把代理与 add_phone 风险验证清楚.
+
+---
+
+## 4. 验收标准
+
+### 必须满足
+
+1. fresh cohort 优先使用带 provenance 的 recent accounts.
+2. first-use / first-invalid 能带上 probe 代理信息.
+3. register worker 默认优先 `tw,sg`.
+4. add_phone 成功号有明确 warmup 字段.
+5. targeted pytest 通过.
+6. 关键回归 pytest 通过.
+
+### 实验输出
+
+本轮完成后要能稳定回答:
+
+1. `tw` 与 `sg` 的寿命是否显著优于 `us`.
+2. `add_phone` 组是否比非 add_phone 组更短命.
+3. 首用代理与注册代理是否一致.
+
+---
+
+## 5. 风险
+
+### 风险 1. strict fresh 区域偏好降低短时吞吐
+
+接受这个风险. 当前目标是先提寿命质量, 不是继续放大低质量产号.
+
+### 风险 2. 旧号 provenance 不完整
+
+这轮通过 cohort 过滤减轻, 不试图补写旧历史事实.
+
+### 风险 3. warmup 标记不等于业务隔离
+
+这轮只做风险标记与实验分层, 不直接改变 CPA 主线语义.
+
+---
+
+## 6. 交付物
+
+本轮交付物只包括:
+
+1. revised plan
+2. fresh cohort hygiene
+3. proxy affinity reuse
+4. fresh region preference
+5. add_phone warmup metadata
+6. docs update
+
+不包含第二阶段长期评分与完整健康状态机.

+# 2026-03-31 指纹一致与短寿命账号治理任务书
+
+## 目标
+
+在不改写 HTTP 注册主线的前提下, 先完成 3 件最短路径工作:
+
+1. 指纹一致: 注册, rotate quota probe, responses survival probe 使用同一套浏览器指纹头.
+2. 实验可观测: survival tracker 能按注册来源字段分组, 支持产出实验报告.
+3. 日志补全: pool 记录与 survival 状态记录注册 provenance, 首次使用, 首次失效.
+
+## 本轮实现范围
+
+### A. 指纹一致
+
+- 新增共享指纹模块: `/home/sophomores/zhuce6/platforms/chatgpt/fingerprint.py`
+- 统一 `ops.scan` 与 `ops.rotate_probe` 的请求头到 `chrome120_win`
+- 不再用 `codex_cli_rs` 或 `Codex Desktop` 作为探测 UA
+
+### B. 短寿命保护
+
+- 新增 `ZHUCE6_ROTATE_FRESH_GRACE_SECONDS`
+- fresh 账号在 grace 窗口内跳过 rotate quota probe
+- 目的: 避免刚注册成功的号立即被 rotate 打首用 API
+
+### C. 注册 provenance
+
+pool 文件新增:
+
+- `registration_fingerprint_profile`
+- `registration_user_agent`
+- `registration_sec_ch_ua`
+- `registration_proxy_url`
+- `registration_proxy_key`
+- `registration_proxy_region`
+- `registration_device_id_hash`
+- `registration_cfmail_profile_name`
+- `registration_post_create_gate`
+- `registration_email_domain`
+- `registration_location`
+
+### D. survival 实验字段
+
+responses/account survival 成员新增:
+
+- `first_use_at`
+- `first_use_age_seconds`
+- `first_use_fingerprint_profile`
+- `fingerprint_consistent`
+- `first_invalid_error_code`
+- `first_invalid_error_message`
+- `registration_proxy_region`
+- `registration_post_create_gate`
+
+### E. 实验报告入口
+
+- 新增脚本: `/home/sophomores/zhuce6/scripts/survival_experiment_report.py`
+- 用于按 `proxy_region`, `post_create_gate`, `fingerprint_consistency` 输出分组中位存活时长
+
+## 验证标准
+
+1. `ops.scan` 的 usage / responses probe 头与注册主线一致.
+2. fresh 账号在 grace 窗口内不进入 rotate quota probe.
+3. 新写入 pool 的注册账号带 provenance 字段.
+4. survival state 中能看到 `first_use_*` 与 `first_invalid_*`.
+5. `scripts/survival_experiment_report.py` 可直接从 tracker 生成分组结果.
