How to Reproduce / 如何复现
微调glm5.2，并且不开启recompute参数
--recompute_granularity full
--recompute_method uniform
--recompute_num_layers 1
若增加以上三个参数，则可以规避该问题

Research direction
Start by reproducing GLM5.2 fine-tuning with recompute disabled, then compare the DSA attention call with the recompute-enabled path. Trace _checkpointed_attention_forward and the dsa-specific x and qr arguments described in the report. Done means the no-recompute path no longer fails with the reported argument-alignment error.
