## Statement

The MRSS Higgs parity is unique conditional on the loaded low-energy scalar spectrum of one weak doublet and no coloured triplet; it is a consistency statement, not a derivation of that spectrum.

## Caution

Uniqueness given the desired scalar content does not derive that content or remove its circularity risk.

## Primary source

Paper 4, §12, A1472 correction: loaded scalar spectrum, PDF p.81: "At A1472 the uniqueness was corrected: it is conditional on the loaded low-energy scalar spectrum — one weak doublet, no coloured triplet."
