- class: RETIRED · review_state: PUBLISHED · house_tier: not yet assigned
- labels as printed: math_status None · attachment None · scorecard tier word none (PDF p.None)
- basis: {"pdf_sha256_prefix": "b64ddcd9e16a6dcd", "release": "Rev33.1_S369"}

## Statement

The archived triality proposal proposed obtaining the charm mass from a geometric combination of the muon and top masses.

## Caution

The current target replaces this physical formula without proving that every triality identity in its absent derivation was false.

## Primary source

Paper 2, §3.6, Current charm boundary value and offset, PDF p.38: "The charm bridge value mc = 1291.9 MeV lies +1.49% above the PDG 2026 MS comparator mc (mc ) = 1272.9 ± 4.5 MeV."
