The separation between MEASURED, ESTIMATED, and INTERPOLATED results gives the 57-run dataset a clearer scope. For the predictive layer, I would add a grouped holdout alongside the held-out configurations you describe: reserve an entire model size or precision/backend combination, then compare its error with ordinary configuration-level validation.

Nearby context lengths from the same model can make a split look reassuring without testing whether the predictor handles a genuinely new regime. Reporting those two errors separately would help users judge a recommendation outside the measured grid. A clear 'outside coverage' signal would also prevent a precise-looking prediction from implying stronger evidence than the dataset supplies.

Thanks Ahmed. Very useful point. I agree that nearby configuration splits can overstate generalization. I’ll add grouped holdout experiments (model size / precision / backend) alongside the current validation, and introduce an explicit “outside coverage” signal for extrapolated predictions. This should make the uncertainty and deployment layer more rigorous.

That would make the prediction layer easier to interpret. I would show the grouped holdout's coverage beside its error: which sizes, precisions, and backends were withheld, and which combinations still have no independent test. One overall grouped score could otherwise conceal a difficult regime behind easier ones.

For the outside-coverage signal, keep the trigger understandable to the user, such as an unmeasured backend or a size beyond the observed range. That explains why a number needs caution instead of displaying uncertainty as an unexplained badge.
