| contents | <p>Suppression is a universal structural law governing operator amplitudes in compactified fixed-point geometries and is not derived in this work. The present study examines the portability of a specific worldsheet instantiation of this law. A geometric suppression factor R = 0.967, derived from a hadronic vacuum polarization (HVP) worldsheet in fixed-point Type IIB string compactification, is tested for applicability in other observables that embed the HVP sector in structurally matching physical contexts. When such context matching holds, the same worldsheet is hypothesized to apply, inducing a corresponding modification of the hadronic contribution to the running electromagnetic<br>coupling, ∆αhad(Q^2). A hierarchy of direct tests, propagated implications, and indirect estimates is constructed to organize falsification of worldsheet portability. Observable-dependent diagnostics are introduced to distinguish failures of portability from kernel-weighting effects</p> |
