V.R89 — Spherical neq static

The spherical carrier predicate does not require staticity. A time-dependent spherically symmetric configuration (e.g., collapsing shell) satisfies Sph(chi) while having nontrivial alpha-orbit evolution on the base. The static condition is an additional equilibrium constraint.
