## Statement

The retained ratio mµ/mτ = (ϕ/√5)^(8/3)·√2/10 = 0.059684 is Structural mathematically, Loaded-correspondence physically and Reproduced numerically.

## Caution

Exact dimension quantities do not by themselves derive their use as a mass exponent and physical normalization.

## Primary source

Paper 2, §3.2, Ratio typing, PDF p.34: "The rows of this subsection therefore stand at Structural (mathematical tier), Loaded-correspondence (physical attachment) and Reproduced (numerical status): the ratio is reproduced, not derived."
