Neutrino ontology and Majorana readout

Neutrinos differ ontologically from photons. A neutrino is not a null-transport mode but an ontic weak-sector eigenmode with in-transit reality: it carries weak-sector structure while remaining electrically neutral and colorless. The three flavor modes _e,_μ,_τ are read as weak eigenmodes of the carrier grammar. In the current τ-readout, zero-holonomy neutrino modes satisfy the Majorana condition; the particle/antiparticle distinction is therefore read through helicity / propagation orientation rather than an independent internal charge. The detailed structural route is recorded in the final quantity-semantics appendix.
