Leptonic CP is Majorana-only: A Registered Prediction Addendum

Leptonic CP is Majorana, not Dirac: A Pre-registered Neutrino-Sector Prediction Set. Pre-registered neutrino-sector prediction set: leptonic Dirac CP conserved (J_lepton=0), CP is Majorana, normal ordering, m_bb ~ 1.8-3.1 meV (NO). Companion prereg JSON + audit scripts. This record is part of the finite-QEC substrate / It-from-Bit publication refresh. 2026-07-01 canon refresh: Zenodo-synced on 2026-07-01: new-record published as 10.5281/zenodo.21100149 (concept 10.5281/zenodo.21100148); local build/render previously checked. 2026-07-03 registered prediction addendum: This version shortens the record into a citable registered addendum and attaches a machine-readable JSON registration. The prediction is that intrinsic leptonic Dirac CP is null, so long-baseline oscillation fits should converge to δCP = 0 or π once matter and degeneracy effects are removed. CP is instead assigned to the Majorana/recovery-orientation sector, with normal ordering, Σmν near 59.7 meV, and mββ in the few-meV band. Falsifiers include intrinsic nonzero Dirac CP, inverted ordering, a cosmological neutrino mass sum far above the normal-ordering floor, or neutrinoless double-beta decay implying mββ at or above the 10 meV scale. 2026-07-08 canon refresh: This version incorporates the 2026-07-08 ANCHOR/DRIFT/PTMS canon refresh and rebuilt local PDF.
