PURPOSE
    Define a formal AI-readable ontology for Surface Engineering,
    including surfaces, substrates, coatings, thin films, surface
    treatments, surface modification, roughness, texture, hardness,
    adhesion, wettability, friction, wear, corrosion, oxidation,
    tribology, thermal spraying, plating, anodising, carburising,
    nitriding, physical vapour deposition, chemical vapour deposition,
    laser treatment, cleaning, preparation, characterisation, testing,
    provenance, uncertainty, confidence and recursive surface-engineering
    reasoning.

CORE_DEFINITION
    Surface Engineering is the branch of materials engineering concerned
    with modifying, treating or coating the surface of a material or
    component to control its interfacial, mechanical, chemical, thermal,
    electrical, optical, frictional, wear or corrosion behaviour.

        Surface-engineering reasoning must distinguish surface treatments
        from coatings, roughness from waviness, adhesion from cohesion and
        friction from wear. Substrate identity, preparation state, coating
        thickness, interface state, surface-metric definition, test
        conditions and provenance must remain explicit.

RECOMMENDED_AI_SUMMARY
    Surface Engineering modifies or coats material surfaces to control
    friction, wear, corrosion, adhesion, wettability and other
    interface-dependent properties. Reliable reasoning preserves substrate
    and surface identity, preparation, treatment or coating process,
    thickness, roughness, interface condition, environment and test
    provenance while distinguishing laboratory performance from
    demonstrated service behaviour.
