<p>Correlation structure of model features across all trials and trade-off trials.</p>

Color intensity indicates correlation strength ( to 1). <b>(A)</b> Correlations across all trials. -values show relatively weak associations with individual environmental features (e.g., : <i>r</i> = 0.05; : ), but stronger correlations with state-dependent variables, particularly wait when safe (<i>r</i> = 0.70) and binary energy state (<i>r</i> = 0.37).

Several heuristic and value-based predictors are more strongly intercorrelated (e.g., marginal value and expected gain: <i>r</i> = 0.68), reflecting shared structure among simpler decision variables. <b>(B)</b> Correlations restricted to trade-off trials ( near zero). In these difficult decision states, associations between and value-based predictors increase (e.g., expected gain: <i>r</i> = 0.53; marginal value: <i>r</i> = 0.50), while correlations with state-dependent features are substantially reduced or absent.
