WHY IT NEEDS A POLICY

Why retexture_model needs a policy

This is a Write operation because it creates or modifies data reversibly. Retexturing produces a new variant of a model rather than executing arbitrary code or irreversibly destroying data. The modification is reversible (the original model persists, a new variant is created).

From the tool's definition Tool name 'retexture_model' and description 'Re-texture an existing model into a new variant' indicate the tool modifies an existing model by changing its appearance/textures, creating a new variant without deleting the original.
