## Statement

For the registered boundary ten B and physical/selector ten P, dim HomKdyn(Sym²B,P) = 2.

## Caution

The available quadratic maps do not choose a copy or derive a physical boundary-to-selector response.

## Primary source

Appendix S, §9.3, Quadratic bridge census: B to P, PDF p.313: "dim HomKdyn (Sym2 B, P ) = 2"
