Geometric C1C_1 transfer for algebraically maximal valued fields

Let (K,v)(K,v) be an algebraically maximal valued field with divisible value group and perfect residue field kk. A field is called geometrically C1C_1 if every smooth projective separably rationally connected variety over it has a rational point. Geometric C1C_1 transfer conjecture.

K is geometrically C1    k is geometrically C1.K\text{ is geometrically }C_1\iff k\text{ is geometrically }C_1.

The surrounding proof fragment indicates that this equivalence is intended as a result relating valued fields to their residue fields, but the supplied text does not establish its status or provide the full statement context.
