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.

Shell plugin: three-column AppFrame (drag handles, concession chain) + ctx.layout viewing-state service (nav, panel widths, persist); defines the sidebar/conversation/details/conversation.empty slots. A closed sidebar retains a 60px control rail while details closes to zero width. Contract: api-contracts v3 §5.
Slot declarations use the composed-props entry form (owner share, no full props): the exported OwnerShare contracts are SidebarOwnerProps / ConvOwnerProps / DetailsOwnerProps / EmptyOwnerProps — registrants reference them via OwnerOf<'sidebar' | ...> and compose their own injected share locally. No entry declares children (declaring it requires the registered component to carry the slots face — reserved for future business slots): delegation authority is the component-side whitelist, i.e. AppFrame's ScopedSlots<FrameSlotKey> face over sidebar/conversation/details/conversation.empty. Since the root-slot rework the frame itself registers into 'root' and renders those child slots at its own render sites; the shell only renders 'root'.
The export surface is the cross-package contract only: the AppFrame trio (+ AppFrameProps) consumed by the web shell's assembly, LayoutService with its store shapes (NavState/PanelState/ViewId), and the OwnerShare contracts. The concession-chain solver (computeColumns) and its geometry constants are package-internal; tests import them from /src.
Model Experience
None, as the layout shell manages browser viewing state; nothing here reaches a model request.
KV Cache effect
None; this package neither assembles nor sends a provider request.
Known Limitations and Deferred Work
- Details open/width state is global — it does not follow the session (arbitrated for P-I); the per-session keyed upgrade slot is reserved.
- Concession-chain auto-close derives a zero width without touching the persisted open flag — the panel restores itself when the window widens; consumers must not read
details.openas the rendered truth. - Scroll anchoring during squeeze reflow is not implemented — deferred with the virtualized-list project.
