How it works

Cerebellum measures which tensor groups survive extreme compression and which don't. This file has 400 tensor-level overrides from group ablation, reverse ablation, and router surgery across all 40 layers.

Key finding: 10 of 11 tensor groups tolerated Q2_K with under 2% degradation. 7 of those actually performed better at Q2_K β€” imatrix-guided Q2_K acts as beneficial regularization on gate/mixing weights in this architecture.

Final BPW: 2.73
