Idea	Status	Tags	Summary
activity_bar			The extension should provide an activity bar sidebar for editor-adjacent requirement context per [consumption.local_graph_view]. UI is implemented as Svelte webview panes per [development_core], not as a long-lived tree of static rows. The host loads slices from the index via [graph_analysers.local_graph_analysis] and forwards editor focus through [activity_bar_webview] and [activity_bar_data]. Panes should be performance conscious: capped neighbourhoods, lazy cytoscape mount, debounced cursor updates — same discipline as [webview_doc.webview]. Workspace-wide tables, full layout controls, and unconstrained graph dumps belong in Ideas Summary per [ideas_summary_doc.ideas_summary]; panes link out with prefilled state instead of duplicating those views.
loading_state	done		After the activity bar shell mounts, the header may appear before pane data. Cover every sequencing beat with an explicit loading or error affordance — never a blank content area: 1. HTML shell ( before Svelte boots ): inline waiting markup in [get_activity_bar_html]. 2. Connecting: header visible; a post-first-frame `ready` handshake starts the index and requests the first host state. 3. Waiting for index: [workspace_panel.workspace_loading]. 4. Ready panes: [current_context_scope.context_panes_loading] and [minigraph.minigraph_loading]. Index sync progress belongs in [workspace_pane]; graph slice waits stay in [miniature_graph_pane], not a second global overlay. Host posts index health on `ready` and on subsequent status changes; soft-waits when the index is not ready instead of erroring the whole bar.
