The Score Rose While the Experiment Stood Still
OPERA evaluates autonomous optical actions with physical residuals, separating reward movement from measurable experimental progress.
Summary
OPERA evaluates autonomous optical actions with physical residuals, separating reward movement from measurable experimental progress.
OPERA represents experimental actions as optical operators and judges outcomes with physically interpretable residuals against withheld references. Across three tasks, score-only feedback increased the score without physical improvement in 23.6 to 39.0 percent of decisions, compared with 0.9 to 1.9 percent under operator-residual feedback. Protocols chosen in digital twins transferred to three optical instruments, but the preprint does not establish general laboratory autonomy.
