Revealed Preference Validation Against Indifference Curves

This draft fills the zero-any accepted-prime gap for indifference_curves by preserving the revealed-choice validation pattern: infer trade-off contours from observed behavior, test those contours for consistency, and bound the inference when constraints or choice architecture distort the signal.

Drafting note

The candidate was treated as a full archetype because no accepted archetype currently covers the inverse problem of deriving and validating indifference contours from actual choices. Nearby economics, optimization, and validation archetypes remain important boundaries, but they do not collapse the distinctive behavioral-inference move.

Compression statement

Revealed Preference Validation Against Indifference Curves treats observed choices as evidence about a decision maker’s implicit substitution rates. It reconstructs candidate indifference contours from choice data, checks them against budget, feasibility, dominance, and consistency constraints, and flags where observed behavior contradicts the claimed preference model.

Canonical formula: valid_preference_surface = observed_choice_set × feasible_budget_set × inferred_substitution_rates × consistency_tests × anomaly_explanation_boundary
