 - 单元与集成测试使用 Bun，命名为 `tests/*.test.ts`；浏览器测试使用 Playwright，专项脚本通常命名为 `*.browser.ts`。
 - 修复问题时覆盖对应回归场景；计价、迁移和同步变更需验证未知值、幂等与失败恢复，不以虚构覆盖率作为门槛。
 - 界面改动检查桌面、移动端和减少动态效果模式；`bun run test:browser` 通过 `METERLEAF_CDP_URL` 连接任务浏览器。截图放入已忽略的 `test-results`，视觉验收由维护者确认。
+- 专项 `*.browser.ts` 脚本读写真实接口，先用 `METERLEAF_DEMO=true bun --no-env-file src/server/main.ts` 起演示后端，再用 `bun run dev` 起页面，`METERLEAF_TEST_URL` 指向该页面的任务标签；`quota-estimate` 自带临时服务，只需要 `METERLEAF_CDP_URL`。
 - 浏览器测试使用独立任务标签；修改 localStorage 时与维护者预览页隔离 origin。CDP 连接放在有 `finally` 清理的脚本内，结束时撤销模拟并断开连接，不在长期 REPL 中遗留 Playwright 客户端；系统主题须在清理后再次刷新验证。
 - 高保真参考与维护者已认可版本是视觉依据，修复前保留其可恢复位置和已知缺陷。代理预审按当前任务要求校对参考、导航和受影响状态，明确偏差先处理；预审通过与维护者最终接受分别记录。维护者接管验收时交出可访问版本和已知限制。
 - 纯文档改动核对对应事实、相对链接、所改 Markdown 的 Prettier 检查与 `git diff --check`，不触发产品完整测试。
