 ### Changed
 
 - Experimental: `GraphSchema` validation now rejects `KEY` and `EXISTENCE` constraints on the same node or relationship property (including composite KEY members), since KEY already implies mandatory presence. Legacy `PropertyType.required` migration no longer adds redundant EXISTENCE constraints for KEY-covered properties. The schema-from-text extraction prompt includes the same rule.
