16.6 Three Prometheus executable substrates

Prometheus contains three instructive scientific packages. They are not interchangeable simulators. One is a dataset-backed neural projection counterfactual, one executes a hydrology model with a documented domain mismatch, and one propagates an optical-property replacement through published radiative-forcing maps. A common architecture must preserve these differences rather than erase them behind the generic word simulation [ Mahadevan , 2026f ] .

The three cases should share an AGENTIC protocol rather than a single ontology. Each package is wrapped in a manifest declaring accessible variables, interventions, costs, stochasticity, and hidden evaluator variables. Discovery and confirmation seeds are disjoint. A skill or workflow learned in one package may transfer only at the level licensed by its types; a common word such as “exposure” does not establish a common mechanism.
