Finding

The displayed reduction50 combines a57 deletion with a7-year change of starting role. Deleting57 from the Fall while retaining rest yields2393, so the2450→2400 relation requires its declared endpoint pairing.

Reassessment

Test the positive four-node reflection in its actual comparison domain.
