Neutron-to-Proton Ratio from Y_p
n/p = 10/71 derived from Y_p = 20/81. Standard BBN gives 1/7 = 10/70; tau-prediction differs by one unit in denominator.

Claim boundary
This page reports a Registry-backed internal result surface. It is not an external validation claim, a scientific consensus claim, or independent acceptance.
Curation rationale
- physics-facing terms: neutron, proton
- result-facing terms: prediction
- technical/internal terms: definition
- candidate is better handled as evidence for an inferred existing public surface
