- class: RETIRED · review_state: PUBLISHED · house_tier: not yet assigned

- basis: {"pdf_sha256_prefix": "b64ddcd9e16a6dcd", "release": "Rev33.1_S369"}

## Statement

The archived Peirce-sector proposal assigned V_cb = λ²/φ and V_ub = λ³/φ, successive powers of the same λ divided by the golden ratio.

## Caution

The current magnitude formulas remain loaded and do not derive the physical CKM matrix from the bare algebra.
