 ## Use this package
 
-The session header keeps the current session title as the lineage breadcrumb; when the session's direct catalog has entries or a read has failed, the descendant-count trigger renders at the start of the header actions band, with no breadcrumb separator. An absent catalog, an empty loading catalog, or a successfully loaded empty catalog hides the count trigger. The trigger opens that direct catalog, reports its total and running counts, and loads nested catalogs only when their rows expand. Select a local child at any depth to open that child's conversation with its exact `{parentSessionId, childSessionId, mode}` address, or use the row's trailing arrow to open the same address in the right Sidebar, preferring a separate pane when room permits.
+The session header keeps the current session title as the lineage breadcrumb; when the session's direct catalog has entries or a read has failed, the descendant-count trigger renders after the preset label in the header actions band, with no breadcrumb separator.

 This package registers the `dsh-resource://subagentchat/session/<child>?parent=<parent>&mode=<mode>` resource and builtin Sidebar tab type. The resource retains the child `SessionReference` directly from its address without refreshing the parent catalog, and releases the reference when the tab record closes. The tab renders the shared `conversation.content` Factory through `sidebar.chat.conversation`, fixes the local View to Chat, and omits the main Conversation header and width controls.

 ## 使用本包
 
-会话页头把当前会话标题作为谱系面包屑；当会话的直接目录有子项或读取失败时，后代数量触发器渲染在页头操作区的最前方，不带任何面包屑分隔符。目录缺席、空目录加载中或成功加载为空时，均隐藏数量触发器。触发器打开该直接目录，报告总数与运行数，并且只在行展开时加载嵌套目录。选择任意深度，即可用该子会话的确切 `{parentSessionId, childSessionId, mode}` 地址打开其对话；也可以使用行尾箭头在右侧 Sidebar 打开同一地址，并在空间允许时优先使用独立分栏。

 本包注册 `dsh-resource://subagentchat/session/<child>?parent=<parent>&mode=<mode>` 资源与 builtin Sidebar tab 类型。资源直接根据地址保留 child 的 `SessionReference`，不刷新 parent 目录，并在 tab 记录关闭时释放 reference。tab 通过 `sidebar.chat.conversation` 渲染共享 `conversation.content` Factory，把局部 View 固定为 Chat，并省略主 Conversation 的 Header 与宽度控制。
