# nb44 v2 — Behavior Eval (n=100/source)

**Verdict**: {summary}

Decisive behavior eval at n=100 GSM8K + n=100 SimpleQA test prompts × 3 conditions
(base / DPO / GRPO). Paired bootstrap CIs on correctness deltas.

Conditions:
- base: Qwen3.6-27B no LoRA
- DPO: nb37 v2 multi-probe FG+RG combined preference, 200 steps
- GRPO: nb43 multi-probe continuous reward, 500 steps (final LoRA, post-peak drift)

LoRA loading: `openinterp.safe_load_qwen36_lora()` v0.2.1 — auto strip + verify.
