shaderFingerprint(graph) covers node id/type/params/ports and edge endpoints only; x/y, collapsed, folded and edge ids stay out. ShaderLibrary keys on it and counts compiles (__gm.shaderCompiles()). Measured before: one compile per preview step of a node drag (12 for a harness drag); after: 0, a param change exactly +1. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
