## Repair

- Refactored by: Insert a Declared Variant, Split into Sibling Subject Folders
- Detected by: a folder level introduced where a variant or a sibling subject folder resolves the collision
- Violated by: relieving pressure downward, by nesting, instead of sideways
- Measured by: nesting-relief count
- Enforced by: placement gate, reshape review
