## Statement

The retained construction δCKM = arctan√(3(ϕ + 5ϕ⁻⁵)) = 68.1297° remains Coincidence-class because the first-principles selection of G7 is absent.

## Caution

Agreement of this numeral with data does not derive G7 or make the circular equal-shift step a selection law.

## Primary source

Paper 3, Candidate Construction 2.1, retained formula, PDF p.53: "G7 = ϕ + 5ϕ−5 , q δCKM = arctan 3(ϕ + 5ϕ−5 ) = 68.1297◦"
