graph_library			Reusable cytoscape-based graph visualization library for force-directed and compound graphs. Provides a mount → sync slice → layout → optional live physics → destroy lifecycle with a simplified API. Implementation lives in ["../../../packages/extension/webviews/shared/graph/graph-cytoscape.ts"], ["../../../packages/extension/webviews/shared/graph/graph-cy-controller.ts"], ["../../../packages/extension/webviews/shared/graph/graph-cy-elements.ts"], ["../../../packages/extension/webviews/shared/graph/graph-cy-interactions.ts"], ["../../../packages/extension/webviews/shared/graph/graph-cy-highlight.ts"], ["../../../packages/extension/webviews/shared/graph/graph-physics.ts"], ["../../../packages/extension/webviews/shared/graph/graph-groups.ts"], and ["../../../packages/extension/webviews/shared/graph/graph-theme.ts"]. Ideas Summary re-exports the shared modules from ["../../../packages/extension/webviews/ideas-summary/lib/"] for backward-compatible import paths. Consumers pass a node / edge slice and sync options; the library owns the cytoscape instance, diffing, layout runs, and optional continuous physics.
layout_physics			defaults to force-directed layout ( fcose ) with animation on, but callers can select other options offered by cytoscape. js. a toggle leaves layout animation and live physics on for force-directed layouts instead of settling immediately. live physics is the custom obsidian-style simulation in ["../../../packages/extension/webviews/shared/graph/graph-physics.ts"] ( force core: ["../../../packages/analytical/src/graph/physics-core.js"] ), regardless of which force-directed batch layout produced the initial settle. forces are central gravity toward the centroid, linear edge springs, and inverse-square node repulsion; every childless node participates, including disconnected orphans. group container constraints live in ["../../../packages/extension/webviews/shared/graph/graph-groups.ts"]: each leaf carries data ( ' groupIds' ); disjoint groups are pushed apart after batch cola / fcose and during Animate; groups that share a member ( multi-membership, e. g. tags ) may overlap around the shared node. the simulation is deterministic ( no randomness ) and converges slowly over tens of seconds, then sleeps; interactions wake it instead of restarting it. dragging pins the held node while the sim keeps running around it; release rejoins the node at rest with no snap; clicks never disturb the sim. cycling the Animate toggle pauses and resumes the same simulation state, so it converges to the same attractor as leaving it on.
