 - Scheduled tasks (`ScheduledTasksDialog`, now a full-page surface on web/desktop) and per-project worktree management (`WorktreesView`, opened from the project menu) render as overlays inside `<main>` in `MainLayout`; the sidebar no longer mounts them.
 - Group-level PR-status polling/indicators and worktree-group drag-to-reorder were removed together with the worktree grouping level; `oc.sessions.groupOrder` is no longer read or written. Worktree PR/branch context lives in the Worktrees surface.
 - Root session menus can quickly create a worktree from the session directory's current branch and move the full session subtree there while idle.
+- Managed Chats never offer the worktree-move action in either the sidebar row menu or the active-session header menu because their directories are not project repositories.
+- Managed Chats use the shared Chats root as their folder scope. Their activity section renders the normal folder tree, and sessions created from a Chats folder are assigned back to that root-scoped folder after their date/session directory materializes. Per-session folder scopes created by older builds remain visible for compatibility.
+- The New session keyboard command inherits the active materialized session directory. Explicit sidebar entry points, including the top New session row and the Chats `+`, open a fresh managed Chat draft instead.
+- The new-worktree keyboard command is a silent no-op while a managed Chat draft is open. It must not retarget that draft to the active project or show a Git/worktree error because Chats never participate in worktrees.
 - Directory loading is demand-driven: the sidebar publishes one complete priority plan for all known project/worktree directories, while the sync layer owns bounded execution.
 - When multiple configured projects are checkouts of the same Git repository, exactly one project owns the shared worktree topology: the configured canonical primary root when present, otherwise the first configured source for that repository. Any worktree path that is also a configured project is omitted from subordinate worktree groups, so every directory has one sidebar location while remaining part of bootstrap demand.
