Solutions follow the numbering of the 6 June 2023 paper. In 2(d), the depicted domain is interpreted as a simply connected Jordan domain and the separating curves are boundary-to-boundary crosscuts. These topological details matter. The square-root construction in 1(b) is the odd transform of a general normalized univalent map, rather than one fixed extremal Koebe function.
