Trained with SkyRL (RLOO-n, FSDP2) on `DCAgent/exp_rpt_pymethods2test-large` from the Qwen3-8B pre-RL base `laion/GLM-4_7-swesmith-...-fixthink`. Checkpoint selected at **global_step 15** by trailing-5 EMA (alpha=1/3) of `reward/avg_raw_reward` over the full training chain (cap step <= 80). ## Training Traces Training-time Daytona/Harbor rollouts for this run are uploaded as a companion dataset: **[penfever/ablation-pymethods2test-seqmean-arm0-tis](https://huggingface.co/datasets/penfever/ablation-pymethods2test-seqmean-arm0-tis)** 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.
