OneReason-0.8B Frontier SFT372 - DAPO-Anchor V2.2 First Source Pass

This repository contains the LoRA policy adapter saved at the first complete traversal of the 17,016-source-group Frontier recommendation stream. The checkpoint is the first atomic recovery point after the source cursor wrapped from cycle 0 to cycle 1.

Training

• Base: OneReason-0.8B competition pretrain model
• Start adapter: Frontier SFT checkpoint-372
• Method: reference-free RLOO with DAPO asymmetric clipping and a calibrated auxiliary GT-set anchor
• Rollouts: G=16, temperature=1.2, legal-SID prefix constraint
• Per window: 32 RL groups, four RL optimizer updates, at most one auxiliary anchor update
• LoRA: rank 64, alpha 64, dropout 0.0

Source-pass boundary

• Source groups: 17,016
• Recovery checkpoint: checkpoint-window-000186-update-000930
• Source cursor: cycle_index=1, offset=88
• This publication contains adapter files only; optimizer state, tokenizer, training data, and recovery metadata are not uploaded.
