 - 本地 `master` 推送门禁 `scripts/check-repository-ci.sh` 必须在 lint 后运行 Jenkins Web Build 所覆盖的 AGC AppSurface 套件，再执行 build、content 和 diff 检查，避免登录 UI 回归只在远端构建阶段暴露；完整 Vitest 仍由 Jenkins 生产构建执行。
+- Gitea `repository-checks` 因此必须和 Frontend / Native jobs 一样先执行 AGC 子包的 lockfile 安装；根目录 `npm ci` 不包含 `@tauri-apps/plugin-http` 等子包依赖，不能用预构建镜像缓存假定它们已存在。
 - 验证：`npx vitest run apps/ai-game-creator-shell/tests/appSurface.test.ts -t "shows a clear login service error|explains a refused login connection|keeps the stored token when startup auth check cannot reach the service"`、`npm run check:git-hooks`、`npm run check:encoding`、`git diff --check`。
