A Contextual Choice within a Fixed Candidate Enumeration
Abstract
Covariate-indexed design selection and fixed-list opportunity cost require explicit context weights and information available before action. Evaluation reports local losses and unrepresented contexts alongside the aggregate. It also keeps candidate discovery outside the fixed-list guarantee. Selecting well within known designs cannot establish that an omitted alternative would not be preferable. This focused synthesis develops an empirical comparison that preserves the terminal action, observation process, and total verification cost. Its proposed tests are prospective; no new simulation run, model-training result, or intervention effect is reported.
