Lam--Litt conjecture: Integrality Implies Algebraicity

implies 1): if the coefficients of $f$ are in $\mathbb{Z}[1/N]$ for some $N$ , then $f$ is algebraic over $\mathbb{Q}[z]$ . Also the version of conjecture of Litt's problem 1 on his website.

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.
