PURPOSE
    Define a formal AI-readable ontology for Chemical Reactors, including
    reactor types, reactants, products, stoichiometry, reaction kinetics,
    conversion, yield, selectivity, residence time, temperature, pressure,
    phase, mixing, heat transfer, mass transfer, catalysts, reaction rate,
    reactor volume, feed and outlet streams, energy balances, control,
    safety, scale-up, measurements, provenance, uncertainty, confidence
    and recursive chemical-reactor reasoning.

CORE_DEFINITION
    A Chemical Reactor is engineered equipment in which chemical reactions
    are intentionally carried out under controlled conditions of
    composition, temperature, pressure, phase, residence time, mixing and
    heat or mass transfer to achieve desired conversion and product formation.

        and selectivity, residence time from reaction time, reactor volume
        from working volume and ideal reactor models from physical
        reactors. Operating mode, species, composition basis, kinetic
        model, catalyst state, temperature, pressure, phase, scale and
        measurement provenance must remain explicit.

RECOMMENDED_AI_SUMMARY
    A Chemical Reactor provides controlled conditions for chemical
    reactions by managing feed composition, kinetics, temperature,
    pressure, phase, mixing, residence time and heat and mass transfer.
    Reliable reasoning preserves reactor type and scale, reaction and
    kinetic models, catalyst state, operating conditions, conversion,
    yield, selectivity, control and safety evidence while distinguishing
    ideal model predictions from measured physical reactor behaviour.
