@ -18,6 +18,7 @@ These features are implemented in the crate now:
- Warm-start positions for graph edits and interaction.
- Barnes-Hut octree repulsion for the 3D solver.
- Spatial-grid approximate repulsion as a simpler fallback.
- Repulsion accuracy sweeps against exact all-pairs ground truth.
- SCC detection for cyclic bodies.
- weak components for broad spatial islands.
- articulation points and bridges for hinge-like connectors.

- `RepulsionMode::BarnesHut` is the default realtime path.
- `RepulsionMode::SpatialGrid` remains available as a simpler local approximation.
- `RepulsionMode::Exact` remains available for small graphs and comparisons.
- `repulsion_accuracy_sweep` and `solver_repulsion_accuracy_sweep` report
absolute/relative error and elapsed time for tuning passes.
