… (amicode#264)
- Move the context tree canvas + keyboard nav + hover-glance into
SessionContextTab (top section, above the stats grid)
- Delete the ContextTreePanel component and its top-panel rendering
from message-timeline.tsx — 192px returns to the chat timeline
- Remove the localStorage collapse toggle (amicode-context-tree-open);
the panel itself is the dismiss gesture
- Engine pause/resume follows component mount/unmount (the parent
<Show when={activeTab() === 'context'}> gates the whole tab)
- sessionHasContextItems gates the graph section (no empty canvas)
- Node clicks, amicode:brain-hover events, and keyboard navigation
continue to work identically
- ADR 0004 status updated from Proposed to Accepted
- context-tree-engine.ts and context-tree-data.ts remain unchanged;
existing tests still pass (21/21)

Summary
Relocates the context tree canvas from the persistent 192px top panel into the context side panel (opened from the progress-circle ring button in the session header). The graph is now on-demand — visible when the researcher opens the context panel, hidden otherwise — reclaiming 192px of prime chat real estate.
