## Statement

The current formula chains use mτ = 1776.93 MeV, vEW = 246.22 GeV and ΛG2 ≈ 260 MeV as three named dimensional anchors, a usage inventory distinct from the abstract scale-class count.

## Caution

The abstract one-class theorem does not by itself supply the relations and uncertainties connecting these empirical anchors.

## Primary source

Appendix X, Table 4, Named operational anchors, PDF p.355: "mτ = 1776.93 MeV (lepton tower + mb via 7/3); vEW = 246.22 GeV (top, pinned by GF ); ΛG2 ≈ 260 MeV (light-quark constituents + mc via 7/3)."
