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

## Statement

For the registered physical/selector ten P and boundary ten B, dim HomKdyn(Sym²P,B) = 1.

## Caution

The dimension count does not select a normalized physical bridge or identify the inequivalent linear modules.

## Primary source

Appendix S, §9.3, Quadratic bridge census: P to B, PDF p.313: "dim HomKdyn (Sym2 P, B) = 1"
