+# ablation-pymethods2test-seqmean-arm0-tis (step 15)
+
+RLOO length-bias A/B ablation, **arm0 = sequence_mean loss reduction WITH TIS**
+(truncated importance sampling). 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.
