## Statement

In the declared coefficient class, imposing A = f(CKdyn) excludes the nonzero Φdiag target rather than selecting it.

## Caution

Casimir-naturality is an additional multiplicity-blind principle, not a consequence of ordinary equivariance.

## Primary source

Appendix E, §8, Casimir-naturality: conclusion, PDF p.178: "Casimir-naturality excludes Φdiag ; it is a refuter, not a selector"
