 - 所有项目、发布、refs、流程和集成状态均调用 `devops-platform-api`，前端不再提供本地 mock 数据降级。
 - 成员权限页调用后端 `/members` 和 `/messages`，维护普通成员账号、项目权限、密码重置和平台消息。

+- 发布中心包含项目、环境、ref/tag、备注、生产确认提示、触发、取消、重试和 Jenkins 状态同步入口。
 - 运行记录展示 Jenkins queue/build、Build URL、开始/结束时间、执行提示、失败摘要和日志摘要。
-- BPMN Viewer 使用 `bpmn-js` 渲染后端流程 XML，并通过进度统计、节点状态 badge、右侧时间线和详情面板展示 queued/running/success/failed/skipped/canceled 状态。
+- BPMN 状态区使用后端流程 XML 和 run steps 作为状态来源，左侧展示节点输出或 Jenkins 构建日志，右侧粘性展示进度统计、节点时间线和详情面板。
 - Agent 作为全局工具从顶部打开，只包含发布风险摘要、失败诊断、Runbook 问答、发布说明草稿，并通过后端 Agent API 创建调用记录。
