te_batch_check on the 5060 Ti (A1/A2 unbatched, B te_batch_size 8): encoder outputs match (relL2 5e-5, shapes equal) but B ran at 0.66x the per-prompt speed (padding to the longest prompt in each batch of 8 on the w4a8 Qwen3.5-9B encoder) and the sampler amplified the float noise into different images (mean abs diff 4-52/255 against a 0.000 A1-A2 floor; the un-batched leftovers were bit-identical).
