## Statement

The registered Peirce first-row weight is the exact product 1/√6 = (1/√2)(1/√3), combining the trace-form block and three-generation normalization.

## Caution

The exact weight does not select the first-row route or establish a universal block-weight functor.

## Primary source

Paper 3, Abstract, Rev29 update: Route-B weight, PDF p.48: "1/ 6 factorises as 1/ 2 · 1/ 3 = 1/ 3! (s499): the 1/ 2 trace-form block times the 1/ 3 three- generation normalisation — a derived product, independent of any kaon fit."
