 `@deepseek-ai/dsh-workflow-workerthread` is the current engine and `@deepseek-ai/dsh-tool-workflow` is the model-facing consumer. A future process or sandbox engine can replace the implementation without changing the tool.
 
+The package root is the Host face. The browser-safe `@deepseek-ai/dsh-workflow/types` subpath contains run identities, metadata, results, and observe-only lifecycle payloads without importing `Agent`, Cordis services, or Host context declarations; Host-only `WorkflowStartRequest` and `WorkflowRun` live behind the package root.
+
 ## Service and run contract
 
 `WorkflowService.start(request): WorkflowRun` validates enough synchronously to reject a malformed meta block, unparseable script, unavailable provider route, or unsupported per-run limit before a run exists. Once returned, `WorkflowRun.result` never rejects: execution failures resolve with `stopReason: 'error'`, and cancellation resolves with `cancelled` within the engine's bounded grace.

 `@deepseek-ai/dsh-workflow-workerthread` 是当前引擎，`@deepseek-ai/dsh-tool-workflow` 是面向模型的消费方。未来的进程或沙箱引擎可以替换实现，而无需更改工具。
 
+包根是 Host face。浏览器安全的 `@deepseek-ai/dsh-workflow/types` 子路径包含运行身份、元数据、结果和仅供观察的生命周期 payload，不导入 `Agent`、Cordis service 或 Host Context 声明；Host 专用的 `WorkflowStartRequest` 与 `WorkflowRun` 只从包根提供。

 ## 服务与运行约定
 
 `WorkflowService.start(request): WorkflowRun` 会同步完成足够多的校验，在运行创建前拒绝格式错误的 meta 块、无法解析的脚本、不可用的提供方路由或不受支持的单次运行限制。返回后，`WorkflowRun.result` 绝不拒绝：执行失败以 `stopReason: 'error'` 兑现，取消则在引擎有限的宽限时间内以 `cancelled` 兑现。
