Session search result reveal
Session 搜索结果显露
Selecting a Session search result opened its conversation while leaving the sidebar in the filtered search view. The user could not see where the Session belonged in the normal Workspace hierarchy. Clearing search alone was insufficient because the owning Workspace could be closed, the Session could be hidden beyond the five-row fold, and either grouped or flat navigation could place the row outside the scrollport.

Problem
Selecting a Session search result opened its conversation while leaving the sidebar in the filtered search view. The user could not see where the Session belonged in the normal Workspace hierarchy. Clearing search alone was insufficient because the owning Workspace could be closed, the Session could be hidden beyond the five-row fold, and either grouped or flat navigation could place the row outside the scrollport.
Decision
WorkspaceBrowser treats result selection as a transition back to normal browsing. It records the target Session id, clears the query, collapses search, and opens the Session. In grouped browsing, SessionTree waits until the current Workspace stream has a complete Host baseline, derives and opens the owning Workspace or Ungrouped group, and transiently reveals the hidden remainder only when the target is behind the five-row fold. Flat browsing needs no fold override.
The normal Session row owns completion of the one-shot reveal. A matching mounted row scrolls itself into the nearest visible position and acknowledges the target id, preventing later renders from repeating the scroll. Starting another non-empty search cancels an unacknowledged reveal. Metadata and content matches use the same transition because both result kinds resolve to a Session id.
Alternatives considered
Preserve the query after opening the Session. This keeps the discovery context but leaves the user in the temporary result list and does not identify the Session's normal location.
Clear search without opening or unfolding the owning group. The conversation would open while its selected row could remain hidden, reproducing the missing-location problem in a different sidebar state.
Persist an expanded-all preference for the group. One navigation would permanently replace the bounded five-row presentation. The reveal instead expands the remainder only for the current tree mount.
Scroll from the browser parent. The parent cannot complete the operation before a folded target row mounts. The row that owns the DOM element performs and acknowledges the scroll.
Consequences
Selecting a result discards the current query and returns the sidebar to normal browsing. The owning group stays open, and its hidden remainder is visible for that tree mount when required, so the selected row supplies both hierarchy context and an on-screen location. Waiting for the current Workspace baseline prevents a reconnect's retained membership from acknowledging the reveal before replacement state arrives. A later search or ordinary render does not repeat the scroll after acknowledgment.
The target row is the only completion signal. If another client archives or moves the Session between result selection and row mount, the reveal remains armed; the row will scroll if it mounts later, unless a new non-empty search cancels the reveal or the browser unmounts.
Testing
UI tests cover a content-only hit in the sixth position of a closed Workspace, pending and reconnecting Workspace baselines, cancellation by a new search, transient group expansion and scroll acknowledgment, and the same one-shot scroll in flat mode. The assembled Web navigation test verifies that one click clears search and leaves exactly one selected Session row in the normal tree. The long-conversation browser test opens its seeded Session with that single-click transition.

问题
选择 Session 搜索结果会打开其对话，但侧边栏仍停留在筛选后的搜索视图。用户无法在常规 Workspace 层级中看到该 Session 的所属位置。仅清空搜索还不够，因为所属 Workspace 可能处于关闭状态，Session 可能隐藏在五行折叠之后，而分组或单列表导航都可能把该行放在滚动区域之外。
决策
WorkspaceBrowser 将结果选择视为返回常规浏览的状态切换。它会记录目标 Session id、清空查询、收起搜索并打开 Session。在分组浏览中，SessionTree 会等待当前 Workspace stream 取得完整 Host 基线，再解析并打开所属 Workspace 或 Ungrouped 分组；仅当目标位于五行折叠之后时，才会临时显露其余隐藏条目。单列表浏览不需要覆盖折叠状态。
常规 Session 行负责完成一次性显露。匹配的行挂载后会将自身滚动到最近的可见位置，再确认目标 id 已处理，避免后续渲染重复滚动。开始另一项非空搜索会取消尚未确认的显露。元数据命中与内容命中都会解析为 Session id，因此共用同一套状态切换。
考虑过的替代方案
打开 Session 后保留查询。 这会保留发现上下文，却仍让用户停留在临时结果列表中，无法识别 Session 在常规层级中的位置。
只清空搜索，不打开或展开所属分组。 对话会打开，但选中行仍可能隐藏，只是把缺失位置的问题带到另一种侧边栏状态。
为分组持久保存全部展开偏好。 一次导航会永久取代有界的五行呈现。本次显露只在当前树挂载期间展开其余条目。
由浏览器父组件执行滚动。 折叠的目标行挂载前，父组件无法完成操作。持有 DOM 元素的行负责滚动并确认完成。
后果
选择结果会丢弃当前查询，并让侧边栏返回常规浏览。所属分组保持打开，并在需要时于该次树挂载期间显示隐藏条目，因此选中行同时提供层级上下文与屏幕内位置。等待当前 Workspace 基线可避免重连期间保留的旧归属信息在替换状态到达前确认显露。确认完成后，后续搜索或普通渲染不会重复滚动。
目标行是唯一的完成信号。如果另一客户端在结果选择与行挂载之间归档或移动了 Session，显露会保持待处理；除非新的非空搜索取消显露或浏览器卸载，否则该行以后挂载时仍会触发滚动。
测试
UI 测试覆盖关闭 Workspace 中位于第六位的纯内容命中、待定与重连中的 Workspace 基线、新搜索取消显露、临时分组展开与滚动确认，以及单列表模式下的同类一次性滚动。组装层 Web 导航测试验证一次点击会清空搜索，并在常规树中只留下一个选中的 Session 行。长对话浏览器测试通过这次单击状态切换打开预置 Session。
