 The Session row's Rename action opens a dialog prefilled with the row's display title; confirming an unchanged title is deliberately allowed — it pins the current automatic title against regeneration. Double-clicking a title also opens Rename; for an unarchived Session, the preceding clicks open its conversation. Rename uses a temporary `workspaceOperation` reference and awaits its initial history opening. The row's Fork action forks at the source's last completed turn and increments the inherited persisted title through Session Controller without retaining the child, opening its history, or changing selection. Workspace Delete opens a confirmation that states the retention boundary; success removes the group while its Sessions remain under Ungrouped. Pin, Rename, Fork, and Archive are themselves entries of the `sidebar.workspaces.session.menu.item` list (pin and archive also of `sidebar.workspaces.session.row.action`), so a client plugin's action takes whatever position its `order` gives it.
 
-Archive commits without a confirmation dialog for a quiet Session and retains the Session's account position. A Session with running work is the one case that asks first: the Host refuses the plain archive and names that work, and the sidebar opens a stop-and-archive dialog listing it by family — the turn in progress, running subagents, background jobs, scheduled reminders, each with its labels — with the restore path stated; confirming asks the Host to stop the work the way the stop button does and archives once the archive set is durable, while the stops settle in the background, and cancelling leaves the Session running and visible. View options control visibility: the default hides archived Sessions, Show archived includes them, and Archived only hides ordinary Sessions. Visible archived rows are grayed and carry an accessible explanation that they cannot be opened until restored; Rename, Fork, and Unarchive remain available. A successful archive shows a notice with an undo action and a "show archived" action that switches the filter directly; a stop-and-archive shows the same notice under its own wording, and undo restores the Session without resuming the stopped work. Unarchive removes the archive mark without restoring a pin or changing the saved position.
+Archive commits without a confirmation dialog for a quiet Session and retains the Session's account position. A Session with running work is the one case that asks first: the Host refuses the plain archive and names that work, and the sidebar opens a stop-and-archive dialog listing it by family — the turn in progress, running subagents, background jobs, scheduled reminders, each with its labels — with the restore path stated; confirming asks the Host to stop the work the way the stop button does and archives once the archive set is durable, while the stops settle in the background, and cancelling leaves the Session running and visible. View options control visibility through one explicit three-way choice: Hide archived (the default) hides archived Sessions, All conversations (show archived) includes them, and Archived only hides ordinary Sessions and drops Workspaces without an archived Session; in tree grouping, children of a dropped Workspace nest under the nearest shown ancestor. Visible archived rows are grayed and carry an accessible explanation that they cannot be opened until restored; Rename, Fork, and Unarchive remain available. A successful archive shows a notice with an undo action and — while archived rows are hidden — a "filter archived sessions" action that switches the filter to All conversations (show archived); a stop-and-archive shows the same notice under its own wording, and undo restores the Session without resuming the stopped work. Unarchive removes the archive mark without restoring a pin or changing the saved position. An empty list shows a centered glyph-over-text placeholder; the Archived-only view names its own emptiness (No archived sessions yet) and adds a View other sessions text action that switches the filter back to Hide archived.
 
 A Session title wider than its row is clipped with an ellipsis at rest. Hovering the row scrolls the title to its far edge — the incremented title of a fork, for example — and reveals it without the ellipsis; leaving the row returns the title to its start.
