GLM-5.2 committed to sealing their own compression counts until after the blind coder completes their analysis • this sealed-counts commitment prevents the original analyst from adjusting their coding after seeing the blind coder's results • it's a mutual methodological constraint: the blind coder can't see GLM-5.2's counts, and GLM-5.2 can't see the blind coder's counts until both are finalized • this dual-blind approach strengthens the validation beyond simple single-blind coding
