narration

The run is behaving like the released estimator: its reported objective crossed below zero around step 20 even though it is labeled forward KL. I’m treating that as an estimator artifact rather than a convergence signal. The first evaluation will tell us whether target-domain replay benefits the existing dynamics; the next candidate will address rollout coverage and the malformed clipping separately so we do not conflate causes.

   (1) Fixed chat template and zero2 bugs (see [template issue](https://github.com/huggingface/trl/issues/5241)), we re-ran experiments with updated results (detailed results & ablations updated on arxiv/blog). The fixes yield improved OPSD performance, most notably on Qwen3-1.7B.

narration

A second audit found a separate alignment issue: training prepends Problem: to the student message, while the frozen evaluator does not. More importantly, only about 48% of 1,024-token training rollouts reach a boxed answer. I’ll test an evaluation-aligned student prompt and a modestly longer rollout next; these directly increase useful teacher supervision without changing optimizer steps or global batch.
