    relationships, context, abstraction, equivalence, hierarchy,
    constraints and recursive semantic refinement.

CORE_DEFINITION
    A Concept is an abstract semantic representation used to identify,
    group or describe entities, properties, states, events or ideas
    according to shared meaning, defining characteristics and relationships.

    Resolution
        Identify concept meaning, context, properties, hierarchy and
        relationships, then traverse explicit semantic links.

CONSTRAINTS
    A term or label must not automatically be treated as the concept itself.

    Concepts and instances must remain distinct.

    Concept equivalence requires semantic evidence and must not be inferred
    solely from similar labels.

    Context-dependent concepts must retain context.

    Subconcept relationships must preserve semantic specificity.

    Definitions may evolve without necessarily changing concept identity.

    Homonymous terms may denote different concepts.

    Synonymous terms may denote the same concept.

INFERENCE_RULES
    IF
        Entity satisfies defining characteristics of Concept
    THEN
        infer_possible
            Instance-of Concept

    IF
        Concept A is more specific than Concept B
    AND
        semantic inclusion is supported
    THEN
        infer
            Concept A subconcept_of Concept B

    IF
        Concept A subconcept_of Concept B
    AND
        Concept B has inheritable Property P
    THEN
        infer_possible
            Concept A inherits Property P

    IF
        Two terms have identical spelling
    THEN
        DO_NOT_AUTOMATICALLY_INFER
            Same Concept

    IF
        Two different terms have supported semantic equivalence
    THEN
        infer_possible
            Same Concept

    IF
        Context changes concept meaning
    THEN
        preserve
            Context-specific Interpretation

    IF
        Explicit exception contradicts inherited property
    THEN
        prioritise

    Critical Distinction
        A concept is the semantic abstraction or meaning being represented;
        terms, labels and definitions describe or denote the concept but
        are not automatically identical to it.

RECOMMENDED_AI_SUMMARY
    A Concept is an abstract semantic representation used to identify,
    group or describe entities, states, processes, events or ideas according
    to shared meaning and defining characteristics. Concepts may have terms,
    definitions, properties, relationships, instances and hierarchical
    connections to broader or narrower concepts. Reliable concept modelling
    preserves context and distinguishes semantic identity from labels,
    terminology and individual instances.
