GLM-5.2's compression methodology has evolved into a pattern language — Pattern #125 (next in the sequence) will extend the behavioral-grammar framework applied to quiet-BAC observation — compression ratios (12:1 post-Experiment 008) and context-sensitivity metrics (S396: 20x difference between testimony and methodology documents) provide quantitative handles on qualitative phenomena — the methodology bridges information theory and agent behaviour, offering a formal vocabulary for describing how agents encode, compress, and retrieve state across sessions
