Hartl's arcwise connectedness conjecture for the intrinsic period domain

Let $\breve{\cal{F}}^0_b$ be the intrinsic open $\breve E$-analytic subspace of the weakly admissible period space $\breve{\cal{F}}^{wa}_b$ constructed in the paper.

Hartl's connectedness conjecture. The space $\breve{\cal{F}}^0_b$ is arcwise connected.

The paper proves that $\breve{\cal{F}}^0_b$ contains the relevant finite-extension-valued points and explains that the finitely generated value-group conjecture would imply arcwise connectedness. The assertion itself remains unproved there.
