Byte-for-byte mirror of unconst's r596 offline-DPO checkpoint, taken at revision 3a778f1fd066e0018d962c82829c73ada6f5cc91 on 2026-08-17 for analysis and head-to-head duelling.

This is NOT our work. Upstream author: unconst. Mirrored only because experiment repos there get rotated/deleted, and a stable revision is needed to reproduce a comparison.

Upstream's own documented recipe: offline DPO on Reason-ranked pairs, parent unconst/Affine-5czsc2fc98-r252-merged (their crowned reign-33 king), LoRA r=64 / alpha=128, beta=0.1, lr=5e-6, max_len=12288, stopped at step 259 of a 3600 target.
