Ecdysis cuts harness training 1.84x

Ecdysis, a runtime-harness training method, reports up to 1.84x faster harness training and an 18.56% lift in reasoning accuracy. The arXiv preprint says batch-level cross-task failure analysis helps distinguish model-specific failures from systematic harness defects before collaborative refinement. Teams evolving agent benchmark baselines should measure harness cost and unseen-task generalization separately; faster self-improvement is not automatically better evaluation.
