 ## 🧭 CI 自动化测试
 
-测试套件通过 Gitea Actions 自动运行（见 `.gitea/workflows/test.yml`）：
+测试套件通过 Gitea Actions 自动运行（见 `.gitea/workflows/checks.yml` 的 `tests` job）：
 
-- **触发时机**：
-  - 推送到 `main` 分支
-  - Pull Request 到 `main` 分支
-  - 手动触发（workflow_dispatch）
-- **运行平台**：ubuntu-22.04
+- **触发方式**：`workflow_run`——「🧰 准备环境」（`prepare.yml`）完成后触发。
+  Prepare 监听 `push:main`、`pull_request`、`workflow_dispatch` 与每日 `schedule`，
+  故推送到 main、对 main 开 PR 或手动运行 Prepare 都会经 Prepare 传导到测试。
+- **运行平台**：standard-ubuntu-22
+- **注**：`checks.yml` 同时包含 commit message 规范校验（`standards` job）。
