## Statement

The selected golden spectrum satisfies the exact internal identity ϕ² + ϕ⁻² = 3.

## Caution

This internal identity does not by itself select the physical readout or remove the hypotheses of the vacuum-selector theorem.

## Primary source

Appendix E, §5, Corollary 1: spectral identity, PDF p.172: "ϕ2 + ϕ−2 = 3,"
