Remark. External benchmark points do not isolate a harness effect [ftip-00CM]

Prime Agent Section 3.1 places native-harness runs beside externally reported ARC-AGI-3 results and explicitly says the external points situate the curves rather than isolate a causal harness effect [karten2026prime, Section 3.1]. That is an empirical comparison under multiple evaluation records, not a matched estimate of one harness field.

A larger score can still be a valid record of the displayed configuration. It does not by itself establish that persistence caused the difference, that the model weights improved, or that the cost-adjusted potential of Definition [ftip-005M] increased.
