Three.js Debugging
Reproduce first. Treat installed source and official history as evidence, not as
background trivia. A domain skill defines the intended mechanism;
$threejs-visual-validation supplies formal image, timing, resource, or
regression proof when the diagnosis needs it.
Keep one case record with the symptom, expected behavior, exact environment, minimal reproduction, first failed contract, local evidence, upstream candidates, constant version matrix, conclusion, action, and limits. Record unknown values as unknown.
