| Sidebar shell plugin for the dsh web client: brand row, New Session action, collapse control, scroll-aware region seat, and bottom-pinned Settings seat. | package-reference |

Summary
dsh-client-ui-sidebar is the sidebar shell of the dsh web client: users see the brand row, start new sessions, collapse into the layout-owned 56px rail, and reach Settings from the bottom-pinned seat, while the scroll-aware region seat hosts the Workspace and Session browser. The Workspace and Session browser rendered into sidebar.workspaces belongs to ui-workspace; this package neither derives its rows nor owns its view preferences. A deployment package can replace the brand mark or name without replacing the New Session control or the rail geometry, and New Session starts the runtime's page-local frontend Session Intent against the explicit, current, or most recently active Workspace. Collapse into the layout-owned 56px rail remains presentation-local.

Use this package
The sidebar is the navigation shell: users see the brand, start new sessions, collapse the rail, and reach Settings. Feature plugins fill its seats — ui-workspace fills sidebar.workspaces, ui-settings registers the trigger row and settings panel at sidebar.settings.
Brand and New Session
The expanded brand row renders sidebar.brand.mark and sidebar.brand.name as independent single slots; the collapsed rail renders the same mark slot. Without occupants, the shell uses the fish mark and a localized local-build label. A complete build stacks a code badge below the label as version[-commit][-dirty], using DSH_CLIENT_VERSION, the optional 7-character DSH_CLIENT_COMMIT_HASH, and DSH_CLIENT_GIT_DIRTY=true; missing version metadata omits the badge. New Session 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.
Collapse behavior
During a live collapse, the expanded content fades out at its current width, the upper controls share one fade and leftward translation into the 56px rail, and the layout's column slide ends the motion. A page that starts collapsed renders the rail statically, and reduced-motion mode disables both transitions. The bottom-pinned sidebar.settings control shares the fade timing but has no horizontal translation.
Scrollbars
Scrollbars in the column are a pointer affordance: the shell rebinds the scrollbar indirection to transparent whenever the pointer is outside the column 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), so revealing a thumb never reflows.
Understand the implementation
Implementation internals — click to expand
The shell is pure composition: SidebarRootComponentProps composes the layout owner share, the global useSessions and useWorkspaces hooks, the declared brand, the sidebar.workspaces and sidebar.settings child slots, and injected startSession plus sidebar-toggle callbacks. There is no plugin store.
Slot discipline
Declaration-aware slots.inject() lets a replacing package activate before or after the sidebar. The foot is the sidebar.settings seat: the sidebar renders only the bottom-pinned layout slot and shares its column state (wide). 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.
Further Exploration
These pages cover the surfaces that fill the shell's seats and the composition model.
- ui-workspace — the Workspace and Session browser rendered into
sidebar.workspaces. - ui-settings — the settings domain base registering the trigger row at
sidebar.settings. - ui-layout — the layout owner whose rail and column state the collapse uses.
- ui-theme — the scrollbar token indirection the shell rebinds.
- Slot system standard — the composition model behind the seats.
Model Experience
None, as the package is a browser-side UI plugin layer that registers nothing model-facing.
KV Cache effect
None; this package neither assembles nor sends a provider request.
Known Limitations and Deferred Work
These limits define what the shell owns versus what its occupants own; they are current package constraints.
- Session state-dot rendering is owned by ui-workspace — no done/error notification sources are available to this shell.
- Workspace browser behavior is composition-owned — grouping, ordering, search, and row state belong to ui-workspace, not this shell.
- "New task completed" unread marking is local viewing state — completion-time > last-seen never reaches the host.
