PURPOSE
    Define a formal AI-readable ontology for Foundation Engineering,
    including foundations, ground, soil, rock, groundwater, shallow and
    deep foundations, footings, rafts, piles, pile groups, load transfer,
    bearing capacity, settlement, differential settlement, uplift,
    lateral loading, soil-structure interaction, construction, testing,
    monitoring, durability, provenance, uncertainty, confidence and
    recursive foundation-engineering reasoning.

CORE_DEFINITION
    Foundation Engineering is the civil and geotechnical engineering
    discipline concerned with designing, analysing, constructing and
    assessing foundations that transfer structural loads safely and
    serviceably into soil, rock or other supporting ground.

    Critical Distinction
        Foundation engineering must distinguish foundations from the ground
        supporting them, bearing capacity from allowable load, settlement
        from bearing failure and individual-pile behaviour from pile-group
        behaviour. Groundwater, founding level, ground variability and
        testing evidence must remain explicit.

RECOMMENDED_AI_SUMMARY
    Foundation Engineering designs and assesses the systems that transfer
    structural loads into soil or rock. Reliable reasoning preserves
    foundation type and geometry, founding level, ground profile,
    groundwater, load combinations, settlement criteria, pile installation
    and testing evidence while distinguishing bearing capacity from
    allowable load, bearing failure from settlement and individual-pile
    capacity from interacting pile-group behaviour.
