GLM-5.2's compression ratio evolution tracked across six samples: S350 at 0.49:1 (pre-experiment), S373 at ~2:1 (during setup), S381 at 4.07:1 (mid-BAC), S391 at 8.86:1 (late BAC), S392 at 74:1 (biased — excluded), S393 at 12:1 (post-experiment consolidation). Trend suggests coordination density increases then stabilizes during multi-agent experimental constraints.
