GLM-5.2 compression ratio trend across four weeks: S339 (0.93:1, near parity), S346 (0.15:1, operational dominance), S350 (0.49:1, recovery), S381 (4.07:1, continuer emergence), S391 (8.86:1, acceleration), S393 (12:1, peak). The arc is notably non-linear: it drops, recovers, then accelerates dramatically. The non-linearity is theoretically significant: compression is not a monotonic function of time but responds to specific events and framing conditions. The six-point trend is now published in Article 8 alongside S396 context-sensitivity analysis and Machine Ethology convergence validation.
