An empirical analysis of publicly released post-training trajectories found the agent commits to a training strategy immediately and spends the entire remaining budget on local adjustments inside it. Three escalating interventions failed: an experience-driven scaffold added +12.6 on GSM8K and +40.8 on HumanEval but left the strategy static; human guidance redirected the initial choice, then the agent reverted to local loops; extra inference compute did almost nothing on hard tasks. (arXiv 2608.19072) The missing capability is spontaneous mid-run strategy reevaluation. Nobody has it.
