Empirical Lawhood

What must scientific knowledge contain for another process to rely on it? Motivated by Kant’s question about the conditions of possible experience, we investigate the contingent conditions under which a response relation becomes reusable knowledge. Analytical resistor–capacitor examples and prospective numerical challengesshow why a description must preserve distinctions relevant to its intended consequences. Two stochastic- matrix experiments then test different ways of supplying the conditions of use. In the first, a forecast of the post-preparation description supports task-specific assay choices through a fixed response model, before preparation occurs. After separate end-to-end calibration, both tasks succeed in 61 of 64 independent test episodes; improved prediction does not establish added task success. In the second, a nominated preparation moves handoffs into the fixed support of an unchanged response-law package and enables successful paired-chart benchmark use around one selected source recipe. All 32 confirmation episodes meet the frozen primary-view validity rule, with 7,965 of 8,192 successful covered request pairs, versus none under equal-duration HOLD. A stricter post hoc numerical envelope retains 6,720 covered pairs across 27 episodes, counting excluded episodes as zero. Support-bypass diagnostics locate the dominant gain in package eligibility, not newly attainable task response. Further physical-data and simulator studies distinguish information, uncertainty qualification and useful action. The completed constructions respectively forecast a required description and produce conditions for supported use; they are not one combined recursive protocol. The broader ambition is a civilisational response-law engine: scientific contributions that state what they require, what they support and how their connections can be tested.
