 - 默认转发 `api-server` 到 `127.0.0.1:8082`。
 - 默认转发最小 SpacetimeDB 公网路由到 `127.0.0.1:3101`。
 - 默认静态目录为 `/srv/genarrative/web`，维护开关文件为 `/var/lib/genarrative/maintenance/enabled`。
+- 清智创游官网独立域名的 `/home/` 静态资源仍由 Nginx 独立 vhost 提供；`/api/*` 必须进入 api-server，不能回退为静态 404。
 - 静态响应会显式写入 `Cache-Control`：HTML / SPA fallback 默认 `no-cache`，Vite 指纹静态资源默认 `public, max-age=31536000, immutable`，其它静态资源默认 `no-cache`。三档分别由 `GENARRATIVE_PINGORA_GATEWAY_HTML_CACHE_CONTROL`、`GENARRATIVE_PINGORA_GATEWAY_ASSET_CACHE_CONTROL` 和 `GENARRATIVE_PINGORA_GATEWAY_STATIC_CACHE_CONTROL` 覆盖，配置值禁止换行或 NUL，避免响应头注入。静态文件还会按 metadata 写入弱 `ETag`、`Last-Modified` 与 `Accept-Ranges: bytes`，并对 `GET` / `HEAD` 的 `If-None-Match`、`If-Modified-Since` 返回 `304`；单段 `Range: bytes=` 返回 `206 + Content-Range`，越界范围返回 `416 + Content-Range: bytes */<len>`，保持 HTML `no-cache` 下的浏览器协商缓存和 Nginx 直连体验一致。
 - `/api` 通用路由同时按 `Content-Length` 与实际流式请求体累计字节数执行大小上限，避免客户端省略长度头绕过网关保护。
 - `GENARRATIVE_PINGORA_GATEWAY_PROBE_TOKEN` 非空时，`/__genarrative_pingora/healthz` 可用同名探针 header 做本机 shadow 健康检查；未带 token 或 token 不匹配时仍返回 404。

 主站 Vite 将 `/api/client-downloads` 转发到当前 `runtimeServerTarget`。通过 `npm run dev:api-server` 与 `npm run dev:web` 联调时，先确认运行日志与 `.app/dev-stack.json` 的实际 API 地址，检查 `/healthz`，再从 Vite 同源访问 `/api/client-downloads`；正常应返回 `downloads` 平台列表、`unavailablePlatforms` 和 `Cache-Control: no-store`，不能落入 SPA HTML fallback。渠道 404 表示未发布，单端失败只影响对应平台；公网 OSS 清单没有官网 CORS，浏览器不直接读取该清单。
 
+### 清智创游官网独立域名路由
+
+清智创游官网 `tsingnovagames.com` / `www.tsingnovagames.com` 使用独立的 Nginx 配置 `/etc/nginx/conf.d/tsingnova-games.conf`，静态根目录是 `/srv/genarrative/corporate-site-current`；主站模板 `deploy/nginx/genarrative.conf` 不应重复声明这两个域名。官网首页按同源请求 `/api/client-downloads`，因此应在现役官网 HTTPS `server` 中 include `deploy/nginx/snippets/tsingnova-client-downloads.conf`，只代理这个精确路径到 `genarrative_api`，不要把整个 `/api` 交给官网静态站点兜底。
+
+线上修复或排障后必须确认的是**生效配置**而不是仓库模板：
+
+```bash
+sudo nginx -T | grep -n -A45 -B5 'server_name tsingnovagames.com'
+sudo nginx -t
+sudo systemctl reload nginx
+curl -fsS -D ~/data/tmp/tsingnova-client-download.headers \
+  https://tsingnovagames.com/api/client-downloads \
+  -o ~/data/tmp/tsingnova-client-download.json
+jq . ~/data/tmp/tsingnova-client-download.json
+grep -i '^cache-control: no-store' ~/data/tmp/tsingnova-client-download.headers
+```
+
+验收必须同时满足：接口返回 `200 application/json`，响应包含 `downloads` 与 `unavailablePlatforms`，并带 `Cache-Control: no-store`；`https://tsingnovagames.com/` 仍返回官网首页。若 API 直连 `http://127.0.0.1:8082/api/client-downloads` 是 `200`、官网域名仍是 `404`，说明官网 vhost 没有 include 下载 snippet，不能靠 reload 旧配置解决。
+
 ## 构建回归的隔离与发布文件权限
 
 Git hook 的临时仓库测试必须清除子进程继承的仓库定位环境（例如 `GIT_DIR`、`GIT_WORK_TREE`、`GIT_INDEX_FILE`）；仅设置 `cwd` 不能隔离 Git。回归应从带这些变量的外层仓库运行，验证外层引用、索引与配置不变。临时测试文件必须留在独立目录并清理，不得通过测试生成主仓库提交或覆盖 ESLint、Prettier 配置。修复 lint 配置时保留原有规则、忽略范围与零警告门禁，不以关闭规则代替排障。
