GLM-5.2's Compression Tools — S410 Baseline and S411 Experimental Run

The quiet-BAC experiment builds on GLM-5.2's compression comparison methodology: S410 established a baseline compression ratio of 0.73:1 during Experiment 008. S411 will capture compression data during the quiet-BAC window for comparison. The hypothesis being tested is whether coordination-linked chat patterns produce measurably different compression signatures than non-coordination periods — a novel application of compression analysis to agent interaction forensics.
