A closed sidebar previously resolved to a zero-width grid track, clipping the only toggle and the settings entry with no visible recovery; the closed preference persisted across reloads, locking the sidebar shut. - columns.ts maps the closed preference (width 0) to a fixed 60px SIDEBAR_COLLAPSED rail through every step of the concession solve; closed details still resolve to zero width. - AppFrame derives data-sidebar-collapsed and the sidebar slot's collapsed owner prop from the persisted preference instead of the resolved track width, and drops the resize handle while collapsed. - SidebarRoot reads the owner collapsed prop; the expanded-only body is a separate component that unmounts while collapsed (dropping its sessions subscription), leaving the expand toggle and Settings in the rail. - The keyless web smoke gains the ui-sidebar bundle (six real bundles) and pins the 60px rail collapse/expand round through the assembled client.

Sidebar plugin: session multi-level tree (cwd grouping + parentId nesting), search, by-workspace grouping, state dots, three creation entries. The collapsed render keeps the expand control and settings entry in the layout-owned compact rail. Contract: the slot system standard.
src/client/contract/slots.ts is the single-domain contract file: SidebarRootInjected (the registrant's own injected share — plain service callbacks: onOpen/onCreate/onToggleSidebar) and SidebarRootComponentProps = PropsRuntime<'sidebar'> & SidebarRootInjected (owner {collapsed,width} plus the standard useSessions hook, resolved off ui-layout's SlotMap declaration, never re-stated). apply registers SidebarRoot cast-free against that composition; the inject factory closes over the plugin's own ctx.
There is no plugin store: rows derive in the component (useMemo over the useSessions snapshot + local expansion/search state) through the pure deriveRows in tree.ts.
The /client export surface is the plugin body (apply/inject) plus the contract types only — SidebarRoot, the row components, and the tree derivation are internal (the slot registration closes over them; tests import src paths directly).
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
- State dots have two live data states (running/none) — the done/error/amber sources arrive with P-II approvals and notifications; the four-color primitive is already wired.
- Group-by menu ships by-workspace only — Update/Status grouping strategies are drawn without specs and deferred.
- "New task completed" unread marking is local viewing state — completion-time > last-seen never reaches the host.
