WHY IT NEEDS A POLICY

Why object_ungroup needs a policy

Ungrouping is a reversible modification of SVG document structure. It changes the organization of visual elements but does not delete data, execute external code, or have financial implications. The operation can be undone by re-grouping, making it a Write operation rather than Destructive.

From the tool's definition Tool name 'object_ungroup' and description indicating it 'ungroups' objects. This reverses a grouping operation on SVG objects, modifying the document structure by ungrouping previously grouped elements.
