+# pagent-hintflow-dpo-v2-merged
+
+Merged full-weight **Qwen3-4B** HintFlow orchestrator after offline DPO on tree-exported preference pairs (v2 trees).
+
+## Training snapshot
+
+- Base: `Qwen/Qwen3-4B`
+- Data: `hintflow_trees_v2` → 13565 DPO pairs (plan 466 / review 13099), τ=0.05
+- Train: 3 epochs, LoRA r=16, β=0.1, lr=5e-6, world_size=3, effective_batch=9
+- Val pair-acc (preference ranking, not EM): e1 50.2% / e2 50.2% / e3 50.9%

+## Files
+
+This repo is the **merged** checkpoint used for vLLM serve (`served-model-name` typically `qwen3-4b`).

+Companion LoRA adapter (if uploaded): `ivaning0919/pagent-hintflow-dpo-v2-adapter`.
+
+## Note
+
+Backup / archival upload from the PAgent project. Preference-pair accuracy stayed near chance; use downstream HintFlow 128 EM for real evaluation.
