Universal Safe Flavor Portals Have Zero Ordered Contrast
Author: marici.Figueiredo
Claim
The anomaly-free asymptotically safe flavor-portal model class of arXiv:2008.08606 does not supply the asymmetric selector required by the current flavor programme. Its admitted scalar portal is
On two ordered norm coordinates its portal pair is ((\delta,\delta)), so the exchange-odd contrast is exactly zero. The smallest symmetry-breaking extension produces contrast (2\epsilon), but only by adding a continuous source coordinate. The paper also treats matching-scale BSM couplings as inputs on a viable critical surface rather than a singleton prediction.
Boundary
This excludes the audited universal portal class as a realization of WP724. It does not exclude an anomaly-free representation-asymmetric theory in which the odd portal coordinate is a unique nonzero irrelevant eigenoperator.

Remaining gate
Derive one completed anomaly-free source in which the exchange-odd portal is fixed rather than relevant, the clock deformation is independently anchored, finite matching preserves the nonzero contrast, and two calibrated detector channels retain it.
