R1032 — ShortCtx × MidRank × HiBeta Ultra 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 → ShortCtx filtered duel preference pairs (dpo_duel_reason.jsonl, 604 lines) under mining/experiments/r1032-vera-offline-dpo-hialpha-midrank-hibeta-shortctx-ultrasuperextrasteps-ep4-midlr / pod /root/r1032/
