Sidebar shell plugin: the wordmark, New Session action, layout-owned collapse control, scroll-aware region seat, and bottom-pinned Settings seat. [ui-workspace](../ui-workspace/README.md) owns the Workspace and Session browser rendered into `sidebar.workspaces`; this package neither derives its rows nor owns its view preferences. Collapse into the layout-owned 56px rail remains presentation-local. Contract: the [slot system standard](../../../.agents/notes/implemented/architecture/2026-07-22-slot-type-chain-implementation.md).

New Session starts the runtime's page-local frontend Session Intent. The runtime targets the explicit Workspace used by a scoped action, otherwise the current Session's Workspace, otherwise the most recently active Workspace; when none exists it clears into the blank New Session page. Workspace-specific controls and the shared picker belong to ui-workspace.

`SidebarRootComponentProps` composes the layout owner share, the global `useSessions` and `useWorkspaces` hooks, the declared `sidebar.workspaces` and `sidebar.settings` child slots, and injected `startSession` plus sidebar-toggle callbacks. There is no plugin store.
|
|
|
|
Scrollbars in the column are a pointer affordance: the shell rebinds ui-theme's [scrollbar indirection](../ui-theme/README.md) to `transparent` whenever the pointer is outside it, and keeps the thumb drawn for 2s after the pointer leaves, so a list nobody is pointing at carries no bar. The reservation that keeps rows from moving belongs to the scrolling region ([ui-workspace](../ui-workspace/README.md)), so revealing a thumb never reflows.
|
|
|
|
The foot is the `sidebar.settings` seat: the sidebar renders only the bottom-pinned layout slot and shares its column state (`wide`); ui-settings registers the trigger row and settings panel there.
|
|
|
|
The `/client` exports are the plugin body (`apply`/`inject`) plus the contract types only; SidebarRoot, the row components, and the tree derivation remain package-internal behind the slot registration.

## Model Experience
|
|
|
|
None, as the sidebar renders the browser session list; nothing here reaches a model request.
|
|
|
|
#### KV Cache effect
|
|
|
|
None; this package neither assembles nor sends a provider request.

## Known Limitations and Deferred Work
|
|
|
|
- **Session state-dot rendering is owned by [ui-workspace](../ui-workspace/README.md)** — no done/error notification sources are available.
|
|
- **Workspace browser behavior is composition-owned** — grouping, ordering, search, and row state belong to [ui-workspace](../ui-workspace/README.md), not this shell.
|
|
- **"New task completed" unread marking is local viewing state** — completion-time > last-seen never reaches the host.
