LFIS-26: Predictive Registry and Empirical Consequences of LFCT Light Frame Infrastructure Series — Volume 26, v1.4.3 This volume collects the broad, cross-regime falsifiable predictions of Light Frame Cadence Theory into a single predictive registry. Each prediction is traced to the formal master spine (LFIS-24) and the extension mechanics (LFIS-25), with no empirical fitting, interpolation functions, or per-regime adjustment. Fourteen predictions span six domains: galaxy dynamics (universal acceleration crossover, dwarf offset, void/filament luminosity, cluster dynamics, RAR floor), cosmology (representational horizon, temperature hierarchy, Hubble tension as routing mismatch, BAO scale and growth-velocity corrections, Planck–CMB temperature identity from inner/outer horizon mirror), particle physics (electroweak crossover from curvature doubling), gravitational physics (luminal gravitational-wave propagation, gravitational slip from cadence asymmetry), and CMB polarisation (EE/TT normalisation from cadence structure). A derivation chain links each prediction to the axiom spine. The full CMB TT prediction complex — readout operator, phenomenology, and carrier-native production model — is collected separately in LFIS-27, LFIS-28, and LFIS-29. This volume records only the cross-domain predictions needed for the general empirical registry. Part of the Light Frame Infrastructure Series. Depends on LFIS-24 (derivation spine) and LFIS-25 (generators and routing fabric). Cross-references LFIS-27 through LFIS-29 for CMB scope boundary.
