48+- 新增 `scripts/ops/cloudflare-dns-plan.{mjs,sh}`，可渲染目标 DNS 记录、可选用 Cloudflare GET API 对比现网，并输出预览用的 `curl` shell 脚本，但默认不写线上 DNS
49+- 新增 `scripts/ops/nginx-sync-plan.{mjs,sh}` 与 `ops/nginx/templates/**`，可按 inventory 渲染 Nginx 配置、检查仓库默认配置是否漂移，并打出包含 `deploy-on-vps.sh` 的部署 bundle
50+- `docs/ops/README.md` 已改为 inventory 驱动的运维流程说明，覆盖 DNS 计划、Nginx bundle、VPS 分发、证书与验证步骤

52 ## risks
53 
54-- 待填写
55+- 本次没有连接真实 Cloudflare zone；`--fetch-current` 和预览 shell 仍需在填入真实 Zone ID / token 后做一次人工核对
56+- 本次没有在真实 VPS 上执行 `deploy-on-vps.sh`、`nginx -t` 或 `systemctl reload nginx`；证书路径、权限和 systemd 服务名仍需线上确认
57+- 真实 inventory 预计放在仓库外，若运维人员绕开 inventory 手工改 Nginx 或 DNS，模板与线上状态仍可能漂移
58 
59 ## next_handoff
60 
61-- 待填写
62+- 在仓库外复制并填写 `scripts/ops/baa-conductor.env.example`，补上真实 VPS 公网 IP、Cloudflare Zone ID 与证书路径
63+- 导出 `CLOUDFLARE_API_TOKEN` 后运行 `scripts/ops/cloudflare-dns-plan.sh --fetch-current --emit-shell ...`，审阅差异和预览脚本
64+- 运行 `scripts/ops/nginx-sync-plan.sh --env <real-env> --bundle-dir <dir>`，把 bundle 分发到 VPS，先执行 `sudo ./deploy-on-vps.sh`，确认 `nginx -t` 后再显式执行 `sudo ./deploy-on-vps.sh --reload`

  5-本目录记录 `baa-conductor` 在 VPS 上的公网入口、Nginx 转发和启用步骤。
  6+本目录收口第四波公网入口的运维步骤。当前方案固定遵守这几个约束：
  7 
  8-## 域名与转发关系
  9+- 公网只暴露 VPS 的 `80/tcp` 与 `443/tcp`
 10+- `mini` / `mac` 回源固定走 Tailscale `100.x` 地址
 11+- 不依赖 `*.ts.net` 的 MagicDNS 名称
 12+- 仓库脚本默认只做 DNS 计划、Nginx 渲染和部署分发，不会直接改线上 DNS
 13+- `deploy-on-vps.sh` 只有显式传 `--reload` 时才会重载 Nginx
 14 
 15-- `conductor.makefile.so`
 16-  - DNS 指向 VPS 公网 IP
 17-  - `Nginx -> upstream conductor_primary`
 18-  - `conductor_primary` 先打到 `mini` 的 `100.71.210.78:4317`
 19-  - `mini` 不可达时回退到 `mac` 的 `100.112.239.13:4317`
 20-- `mini-conductor.makefile.so`
 21-  - DNS 指向同一台 VPS
 22-  - `Nginx -> upstream mini_conductor_direct -> 100.71.210.78:4317`
 23-  - 用于直连 `mini` 做调试、健康检查和手工运维
 24-- `mac-conductor.makefile.so`
 25-  - DNS 指向同一台 VPS
 26-  - `Nginx -> upstream mac_conductor_direct -> 100.112.239.13:4317`
 27-  - 用于直连 `mac` 做调试、健康检查和手工运维
 28-
 29-统一原则：
 30+`control-api.makefile.so` 的 Worker 自定义域仍由 Cloudflare Worker / D1 相关任务管理，不在这里的脚本覆盖范围内。
 31 
 32-- 只有 VPS 对公网暴露 `80/tcp` 与 `443/tcp`
 33-- `mini` 与 `mac` 的 `4317` 只应通过 Tailscale 或 WireGuard 被 VPS 访问
 34-- `conductor.makefile.so` 不加 Basic Auth，留给统一入口使用
 35-- `mini-conductor.makefile.so` 与 `mac-conductor.makefile.so` 默认启用 Basic Auth
 36+## 单一来源 inventory
 37 
 38-## 仓库文件与 VPS 目标路径
 39+本任务把公网域名、VPS 公网 IP、内网 Tailscale `100.x` 和 Nginx 安装路径收口到一份 inventory：
 40 
 41-仓库中的配置与 VPS 上建议路径一一对应：
 42+- [`scripts/ops/baa-conductor.env.example`](../../scripts/ops/baa-conductor.env.example)
 43+- [`scripts/ops/cloudflare-dns-plan.sh`](../../scripts/ops/cloudflare-dns-plan.sh)

 54-```
 55+推荐做法：
 56 
 57-`ops/nginx/baa-conductor.conf` 里写的是实际 VPS 路径，部署时应直接按这个目录结构放置。
 58+1. 把 `baa-conductor.env.example` 复制到仓库外的私有路径
 59+2. 在那份私有 inventory 里填写真实 VPS 公网 IP、Cloudflare Zone ID 和证书路径
 60+3. 用同一份 inventory 先出 DNS 计划，再渲染 Nginx bundle
 61 
 62-## 前置条件
 63+## 当前域名与内网关系
 64 
 65-部署前确认：
 66+| 公网域名 | Cloudflare DNS 目标 | VPS 上的 Nginx upstream | 内网实际回源 |
 67+| --- | --- | --- | --- |
 68+| `conductor.makefile.so` | VPS 公网 IP | `conductor_primary` | `mini 100.71.210.78:4317` 主，`mac 100.112.239.13:4317` 备 |
 69+| `mini-conductor.makefile.so` | VPS 公网 IP | `mini_conductor_direct` | `100.71.210.78:4317` |
 70+| `mac-conductor.makefile.so` | VPS 公网 IP | `mac_conductor_direct` | `100.112.239.13:4317` |
 71 
 72-1. VPS 已安装 `nginx`
 73-2. VPS 能通过 Tailscale 或 WireGuard 访问：
 74-   - `100.71.210.78:4317`
 75-   - `100.112.239.13:4317`
 76-3. 三个域名都已解析到 VPS 公网 IP
 77-4. TLS 证书已经准备好，或已经决定使用哪种签发方式：
 78-   - Let’s Encrypt：默认路径 `/etc/letsencrypt/live/<hostname>/`
 79-   - Cloudflare Origin Cert：把配置中的证书路径改成实际落盘位置
 80-5. 若要启用 Basic Auth，VPS 已安装 `htpasswd` 所在包：
 81-   - Debian/Ubuntu 通常是 `apache2-utils`
 82+统一原则：
 83 
 84-## 部署与启用步骤
 85+- 三个公网 host 都解析到同一台 VPS
 86+- 只有 VPS 对公网暴露 `80/443`
 87+- `4317` 只允许 VPS 通过 Tailscale 或 WireGuard 访问
 88+- `mini-conductor.makefile.so` 与 `mac-conductor.makefile.so` 默认保留 Basic Auth
 89 
 90-以下步骤假设系统使用 Debian/Ubuntu 风格的 Nginx 目录。
 91+## Cloudflare DNS 计划
 92 
 93-### 1. 安装依赖
 94+### 1. 准备 inventory
 95 
 96 ```bash
 97-sudo apt-get update
 98-sudo apt-get install -y nginx apache2-utils certbot
 99+cp scripts/ops/baa-conductor.env.example ../baa-conductor.ops.env
100+$EDITOR ../baa-conductor.ops.env
101+export CLOUDFLARE_API_TOKEN=...your token...
102 ```
103 
104-如果证书通过 Cloudflare DNS challenge 或其他方式获取，按你的现有流程安装对应插件。
105+注意：
106+
107+- 真实 inventory 建议放仓库外，避免把公网 IP、Zone ID 或 token 变量名混进提交
108+- token 不写进文件，脚本从 `BAA_CF_API_TOKEN_ENV` 指定的环境变量读取
109 
110-### 2. 验证 VPS 到 mini/mac 的内网连通性
111+### 2. 只看目标记录
112 
113 ```bash
114-curl --fail --max-time 3 http://100.71.210.78:4317/healthz
115-curl --fail --max-time 3 http://100.112.239.13:4317/healthz
116+scripts/ops/cloudflare-dns-plan.sh --env ../baa-conductor.ops.env
117 ```
118 
119-任一命令失败时，不要继续启用公网入口，先修好 VPS 到节点的链路。
120+这一步只渲染期望记录，不访问 Cloudflare API。
121 
122-### 3. 准备目录并安装配置
123+### 3. 读取现网并生成变更预览
124 
125 ```bash
126-sudo install -d -m 0755 /etc/nginx/includes/baa-conductor
127-sudo install -m 0644 ops/nginx/includes/common-proxy.conf /etc/nginx/includes/baa-conductor/common-proxy.conf
128-sudo install -m 0644 ops/nginx/includes/direct-node-auth.conf /etc/nginx/includes/baa-conductor/direct-node-auth.conf
129-sudo install -m 0644 ops/nginx/baa-conductor.conf /etc/nginx/sites-available/baa-conductor.conf
130-sudo ln -sfn /etc/nginx/sites-available/baa-conductor.conf /etc/nginx/sites-enabled/baa-conductor.conf
131+scripts/ops/cloudflare-dns-plan.sh \
132+  --env ../baa-conductor.ops.env \
133+  --fetch-current \
134+  --emit-shell .tmp/ops/cloudflare-dns-preview.sh \
135+  --output .tmp/ops/cloudflare-dns-plan.json
136 ```
137 
138-如果默认站点会抢占 `80/443`，按你的发行版习惯移除或禁用默认站点。
139+这一步会：
140+
141+- 用 Cloudflare DNS GET API 读取当前记录
142+- 输出 create / update / delete 计划
143+- 生成一个 `curl` 预览脚本，供人工审阅后再决定是否执行
144+
145+安全边界：
146+
147+- 脚本本身不会发 `POST` / `PATCH` / `DELETE`
148+- `--emit-shell` 只是把预览命令写到文件里，不会自动执行
149+
150+## Nginx 渲染与部署 bundle
151 
152-### 4. 准备直连域名的 Basic Auth
153+### 1. 渲染并打包
154 
155 ```bash
156-sudo htpasswd -c /etc/nginx/.htpasswd-baa-conductor conductor-ops
157+scripts/ops/nginx-sync-plan.sh \
158+  --env ../baa-conductor.ops.env \
159+  --bundle-dir .tmp/ops/baa-conductor-nginx
160 ```
161 
162-建议：
163+bundle 内会包含：
164+
165+- 渲染后的 `etc/nginx/sites-available/baa-conductor.conf`
166+- 渲染后的 `etc/nginx/includes/baa-conductor/direct-node-auth.conf`
167+- 当前的 `common-proxy.conf`
168+- `inventory-summary.json`
169+- `DEPLOY_COMMANDS.txt`
170+- `deploy-on-vps.sh`
171+
172+### 2. 校验模板是否仍与仓库默认配置一致
173 
174-- 至少给 `mini-conductor.makefile.so` 和 `mac-conductor.makefile.so` 打 Basic Auth
175-- 如果运维来源 IP 固定，再把 allowlist 打开，形成“双保险”
176-- 如果域名经过 Cloudflare 代理，先配置真实 IP 恢复，再使用 `allow/deny`
177+```bash
178+scripts/ops/nginx-sync-plan.sh \
179+  --env scripts/ops/baa-conductor.env.example \
180+  --check-repo
181+```
182 
183-### 5. 准备 TLS 证书
184+这一步用于维护仓库里的默认模板和默认配置，不是线上部署必需步骤。

186-仓库配置默认引用：

199+ssh root@YOUR_VPS 'cd /tmp/baa-conductor-nginx && sudo ./deploy-on-vps.sh --reload'
200 ```
201 
202-两种常见做法：
203+行为说明：
204 
205-- 直接 Let’s Encrypt：在 DNS 已生效且 `80/tcp` 可达时，用 `certbot` 申请三张证书，或一张覆盖三个 SAN 的证书
206-- Cloudflare 代理：改用 Cloudflare Origin Cert，并把 `baa-conductor.conf` 中的路径改成你实际存放的位置
207+- 第一个 `deploy-on-vps.sh` 会安装文件并执行 `nginx -t`，但不会 reload
208+- 只有显式传 `--reload` 时才会执行 `systemctl reload nginx`
209 
210-如果证书文件还不存在，`nginx -t` 会失败；先准备好证书，再启用 `443` 配置。
211+## 前置条件
212+
213+部署前确认：
214+
215+1. VPS 已安装 `nginx`
216+2. VPS 能访问：
217+   - `100.71.210.78:4317`
218+   - `100.112.239.13:4317`
219+3. 三个公网域名都已准备好 DNS 记录
220+4. 证书路径已经与 inventory 一致
221+5. 若启用 Basic Auth，VPS 已安装 `htpasswd`
222 
223-### 6. 做语法检查并启用站点
224+常见依赖：
225 
226 ```bash
227-sudo nginx -t
228-sudo systemctl enable nginx
229-sudo systemctl reload nginx
230+sudo apt-get update
231+sudo apt-get install -y nginx apache2-utils certbot
232 ```
233 
234-首次部署且 Nginx 尚未运行时，把最后一条替换为：
235+若证书通过 Cloudflare DNS challenge 或其他流程签发，按现有方式安装对应插件。
236+
237+## Basic Auth 与证书
238+
239+直连域名默认引用：
240+
241+- `auth_basic_user_file /etc/nginx/.htpasswd-baa-conductor`
242+- `mini-conductor.makefile.so`
243+- `mac-conductor.makefile.so`
244+
245+准备 Basic Auth：
246 
247 ```bash
248-sudo systemctl start nginx
249+sudo htpasswd -c /etc/nginx/.htpasswd-baa-conductor conductor-ops
250 ```
251 
252+准备证书时，仓库默认按 Let’s Encrypt 路径渲染：
253+
254+- `/etc/letsencrypt/live/conductor.makefile.so/fullchain.pem`
255+- `/etc/letsencrypt/live/conductor.makefile.so/privkey.pem`
256+- `/etc/letsencrypt/live/mini-conductor.makefile.so/fullchain.pem`

259+- `/etc/letsencrypt/live/mac-conductor.makefile.so/privkey.pem`
260+
261+若改用 Cloudflare Origin Cert，就把 inventory 里的证书根目录改成实际落盘位置，然后重新生成 bundle。
