License Compatibility Check

Map parent and child licenses into canonical rights vectors, compare them across frameworks, and produce a compatibility verdict with reason codes and the required child license. Use as a standalone entry point when you only need to know whether a derivative work can legally adopt a given license, or embed it as steps 2 and 3 of the full IP License Election and Attestation workflow.
