- 09:12 prepared a negative-only Qwen3 GSM8K fixed-batch reward diagnostic rerun after the lr=-1 control failed because PyTorch optimizers reject negative learning rates; the rerun flips normalized fitnesses while using a positive optimizer step size
- 09:33 fixed the negative-only Jean Zay reward diagnostic bootstrap quoting after the first submit retry reached bootstrap but passed escaped dataset-name quotes into python
- 09:39 submitted 20260826-093813-qwen3_4b_gsm8k_fixed_batch_reward_signal_negative_jean_zay-620a35d (job 1399520 on jean-zay, commit 620a35d)

- 17:40 fetched and reported the negative-only Qwen3 GSM8K fixed-batch reward diagnostic; it completed the missing lr=-1 control and did not reproduce the sustained positive-lr center-model gain
