If gamma is quadratic-optimal, the absolute pairing integral is at most sqrt(information mu pi hscore) times wassersteinDistance mu nu toReal. Measurability, integrability and finite real cost identification are proved, not added as pairing premises.",

Uses the existing chosen RN total-gradient smooth finite branch, not a Sobolev or infinite-energy extension. No source repair or domain equivalence is accepted. Route priority remains representative/score-Fisher identification, finite-entropy source-law domain, then endpoint one-sided versus two-sided first variation; the actual klDiv.toReal consumer is only a conditional integration test.
