Familiar priors hurt agent performance once the governing relation is altered, and strict success on Historical counterfactuals was 0 percent for all five Codex models tested.

Its authors name environmental verifiability as the central systems constraint on agent autonomy: evidence must be timely, attributable, and affordable, or the agent cannot tell whether a new observation supports or challenges its hypothesis. Workflow automation alone, they argue, does not constitute scientific discovery. The distinction matters for anyone selling an agent to a laboratory. A system that executes a protocol flawlessly but cannot say what would count as evidence against its own conclusion is a workflow runner, not a research partner, and its failures will look like confident, well-formatted errors.",

Approximately 48 percent of one model's failures involve near-perfect explanations without a symbolic equation: the agent can describe the result well while failing to identify the underlying equation.

The system was validated through a photoresist polymerization campaign using a 405 nanometre laser, with ATR-FTIR showing reduced acrylate-band absorbance. Adaptation is therefore not only software: the lab itself changes shape to fit the workflow, which makes the verification question more urgent, since a changed setup must still produce checkable evidence.",

Agents can investigate counterfactual worlds and adapt physical labware, but the evidence behind each step must be timely, attributable and affordable enough for a human expert to check without redoing the work. Until that check is cheap, the sensible deployment keeps experts in the loop at exactly the points where verification is hardest: recovering a symbolic law, recording a result, and adapting a physical setup. The open question is not whether agents can run scientific workflows. It is whether the proof behind each step can be checked. The perspective paper behind that gap proposes a three-stage framework of reasoning, execution, and world-interaction, noting that current agents excel at digital workflow execution while lacking the capacity to integrate physical experimental evidence into iterative hypothesis revision. A laboratory that prints its own holders is therefore only as trustworthy as the check on what those holders enabled.",
