  "abstract": "We construct a real meromorphic function $F$ on $\\mathbb C$ such that $F^{-1}(\\{0,1,\\infty\\})\\subset\\mathbb R$, while $F$ is not of bounded type in either half-plane. More strongly, for every $a\\in\\widehat{\\mathbb C}\\setminus\\{0,1,\\infty\\}$, the $a$-point divisor in either half-plane fails the Blaschke condition. Thus the construction gives a negative answer to the half-plane bounded-type question arising from Nevanlinna's 1925 work. Postcomposition gives the analogous counterexample for any prescribed triple of distinct values in the Riemann sphere. The core construction and proof were generated during an autonomous run of GPT-5.6 Sol Ultra.",
