Bloch and Landau constants
Ahlfors and Grunsky also conjectured in [AG37] that this upper bound is the precise value of the Bloch constant.

Statement artifacts, not proofs
These records expose exact Lean propositions and statement-only wrappers. Defining a proposition does not supply a proof of it. A placeholder-bearing target also contains no proof. Elaboration checks syntax and types; it does not certify that a formalization perfectly captures every nuance of the informal problem.
