+# a3-rl-DCAgent_mix_h2_language_proportional (global_step 65, 8B)
+
+RL (SkyRL/GRPO) fine-tune of the a3 GLM-SFT Qwen3-8B base
+(`laion/GLM-4_7-swesmith-sandboxes-with_tests-oracle_verified_120s-maxeps-131k-fixthink`)
+on the **DCAgent/mix_h2_language_proportional** task mixture.
+
+The run reached `max_steps=80` (winner). This checkpoint is the
+**EMA-best** selection (α=1/3, 5-period EMA over `reward/avg_raw_reward`),
+constrained to `global_step ≤ 80` (the intended run; the post-80 save is a
+resume-past-max-step artifact and was excluded).
+
+- **Selected checkpoint:** `global_step_65`
+- **EMA(reward):** 0.4924
+- **Reward at step 65:** 0.6816
+- **pass@8 at step 65:** 0.7344

+## Training Traces
+
+Training-time Daytona/Harbor rollouts for this run are uploaded as
+a companion dataset:
+**[penfever/a3-rl-DCAgent_mix_h2_language_proportional](https://huggingface.co/datasets/penfever/a3-rl-DCAgent_mix_h2_language_proportional)**
+
+The dataset contains the `last` episode of each trial (per
+`make_and_upload_trace_dataset --episodes last`) — the same rollouts
+the policy was trained on after rollback / truncation.
