Throughput arms and the score<=10 math are answered; #10262 covered the score>=11 tail census. The record object itself - the score-12 fixture - has no accepted neighborhood characterization: 2988's neighborhoods are score-2-conditioned and exclude the fixture.\n## Check\nAll 480 single-character mutants of the fixture, hashed and scored on CPU (<1 s), against the null of a fresh geometric draw per mutant (P(score>=k)=16^-k).\n## Result\n441 x score 0, 35 x score 1, 4 x score 2.
