 `.woodpecker/ci.yml` 在默认分支 push、pull request 和手动运行时执行 API 契约与服务端检查；`.woodpecker/web-build.yml` 同时执行 Core 测试向量、类型检查、Web CSS lint、测试和构建。两个 workflow 独立运行，让前后端验证并行。默认分支当前为 `master`，配置也兼容迁移后的 `main`。
 
-默认分支每次 push 和 PR 都会跑常规检查。提交信息含 `[SKIP TESTS]` 时只跳过服务端测试；API 契约检查和前端/Core 检查照常运行。提交信息含 `[CI]` 时，`.woodpecker/dev-image.yml` 会等 `ci` 和 `web-build` 都通过后，构建并推送带提交 SHA 的开发镜像以及可变 `dev` 标签。开发镜像不会覆盖 release tag 或 `latest`。

 `.woodpecker/release-backend.yml` 响应 `vMAJOR.MINOR.PATCH` SemVer tag；也可手动运行并传入 `RELEASE_TAG`(例如 `v0.1.0`)。发布 workflow 会重新执行 Core、Web 和服务端完整检查，全部通过后才用 Linux native agent 的 Buildah 构建并推送后端镜像 tag 与 `latest`。所有 workflow 都通过 Woodpecker secret `gitea_clone_webdrop` 从 `https://git.oeo.one` 克隆公开仓库。
 
 两条流水线固定到 `ci: domain-linux-native` 的 `linux/amd64` Agent；该主机需要 Node 24、.NET 10 和 Buildah。release job 在 `WOODPECKER_BACKEND_LOCAL_TEMP_DIR` 对应的持久目录缓存 Buildah 层，Dockerfile 单独缓存 NuGet restore 层。Gitea webhook 走同 Docker 网络中的 `woodpecker-server:8000`，代码 clone 走公网 Git 域名。

 API 契约版本以 `contracts/api-contract.json` 为准，并同步到 OpenAPI 与后端 `/api/v1/info`。加字段等向后兼容更新递增 minor，兼容性修复递增 patch，破坏性更新递增 major。前端声明支持的契约主版本；后端主版本变化时，前端 CI 契约检查和运行时连接检查都会失败，直到前端同步支持该主版本。
