graph_ui_persistence

Key and Controls state is stored in VS Code ExtensionContext. workspaceState under key GRAPH_UI_WORKSPACE_STATE_KEY ( reqlan. ideasSummary. graphUi ).
Shape and normalisation live in graph-ui-state.ts; the host reads / writes it from ideas-summary-panel.ts.
On webview ready the extension posts graphUiState; the webview posts persistGraphUiState ( debounced ) whenever AppState. patchGraphUi runs in app.svelte.ts.
Persisted fields: showKey, showControls, hiddenNodeTypes, layoutId, useCompound, compoundBasisId, animatePhysics, labelMode, maxNodes, truncationBasis, and the five physics sliders ( gravity, repulsion, linkStrength, linkDistance, damping ).
GraphView in GraphView.svelte treats app. graph. ui as the source of truth and applies layout / physics / hidden types / label mode to GraphCyController when those fields change.
The first graph load waits for graphUiState so restored node budget is included in loadGraph.
