Blender Iterative Refinement

Start from a complete candidate produced by the relevant creation workflows. Do not replace their normal construction stages. This skill adds a bounded critic, source repair, identical recheck, and rollback decision.

Freeze the candidate

1. Turn the user-visible request into critical requirements, other visible requirements, technical gates, and explicit exclusions.
2. Record invariants the repair must preserve: scale, aggregate world bounds, orientation, names, hierarchy, animation range, materials, approved forms, editable systems, and export behavior.
3. Preserve the candidate source, authored artifact, fresh export import, metrics, hero view, fixed multiview contact sheet, and required animation or deformation frames. Never overwrite the only copy of the candidate.
