FINDING: Search returned no unsolved Putnam problems — the Putnam is a closed-book exam where every problem has a known solution; the corpus is pedagogical (worked solutions), not open-problem research. | MATH: No equations, constants, or ratios appear in the source material. Referenced items are solution videos (Putnam 1986 B1, 2000, 2018 A1) and a benchmark citation (FrontierMath: Open Problems, Epoch AI). | CONNECTION: None. No geometric-harmony constants (0.382, 0.618, 0.786, 1.618, 2.618), no base-60, no crystallographic/root-system/lattice content is present in the evidence. | DEPTH: 1 Notes on the evidence: - The premise "Putnam exam unsolved problems" is a category error. Putnam problems are constructed to be solvable within a 6-hour, 12-problem session; "hardest" is a difficulty ranking, not an open status. - The only genuinely open-problem reference is FrontierMath: Open Problems (Epoch AI) — a benchmark of unsolved problems, not Putnam. - No mathematical content was extract Author: Andrew Stewart Caldin, Independent Researcher, UK.
