ModelledParticle Property Audit
Systematic comparison of CPT framework predictions vs measured particle properties. Charge, spin, mass, and magnetic moment for the electron, proton, neutron, and photon.
Audit Purpose
The particle audit is a systematic accountability exercise. For each fundamental and composite particle, we ask: does the geometric CPT framework correctly predict its quantum numbers and properties?

Summary Status
Overall audit tallies: 8 properties Exact [E], 5 properties Modelled [M], 3 properties Open [O], and 0 properties Falsified [F] on this particle-row table. That is not a scoreboard of research lines. Mechanisms have been killed (nucleon-mass WKB, barrier-class E₀, local hold on leftover R=1, licensed F5 selectors, S³ Hubble, …). See /validation/known-failures. Open areas on this table involve anomalous moments and charge radii.
