This Skill resolves common issues with brepjs's stable reference (topological naming) system and history replay functionality, which cause geometry selections to break after model edits, references to resolve to incorrect or missing entities, and parametric edits to target the wrong shape features.
Use the shaperef-lineage skill to debug a ShapeRef that returns not-found for a filleted edge after editing an upstream parameter by verifying the role table was updated across the edit operation and the ref uses the correct geometric fallback resolution path for derived geometry.

To fix BrokenRef errors for fillet and chamfer faces in brepjs, verify the role table was updated across the edit operation and ensure the reference uses the correct geometric fallback resolution path for derived geometry.
History replay errors in parametric CAD workflows occur when role tables fail to propagate correctly during edits, causing selections to be lost or re-targeted to incorrect shape features after upstream parameters change.
Debug ShapeRef resolution failures by verifying role table propagation across edit operations, checking reference kind dispatch logic, and implementing geometric fallback resolution for derived geometry like fillets and chamfers.
Geometric fallback resolution for derived geometry references in brepjs can be used to recover fillet and chamfer face selections that return BrokenRef errors after base model edits, ensuring stable topological naming persists.
