R1008 — MidCtx × HiRank × MidBeta Mega MidLR (offline DPO on vera king)
Affine SN120 challenger for Reason v4 (weight_version_key=7): tempered
multi-sample log-mean-exp over k=3 teacher refs (τ=0.03).
Per turn: a_i = lpC(y_i|z_A) − lpC(y_i|∅);
Reason = τ·log(mean_i exp(a_i/τ)). Crown also needs median stripped |z|≥80
and B pass ≥0.30.
How this checkpoint was trained
- Base / parent:
vera6/affine-5g4yy75zuz-t6@8e3f1695e058837ed80fec3238ff439fdc2d0f0e(live king reign36) - Method: offline DPO on Reason-ranked duel pairs (not SFT / not online GRPO)
- What was optimized: preference for thoughts that raise teacher-side Reason (commit to a teacher next-action mode; filler loses under LME)
- Data: Soft Mid Mid Soft × MidCtx filtered duel preference pairs from
