PURPOSE
    Define an AI-readable semantic ontology for Entity,
    including identity, type, properties, identifiers, relationships,
    context, state, provenance, equivalence, resolution and recursive
    entity reasoning.

CORE_DEFINITION
    An Entity is a distinguishable thing represented within a semantic
    system as having an identity that may be associated with one or more
    types, identifiers, properties, states, relationships and contextual
    or provenance information.

        Semantic entity
        Entity identity

    Resolution
        Identify candidate entity, identifiers, type, properties,
        relationships, context and identity evidence.

CONSTRAINTS
    Entity identity must remain distinct from labels and identifiers.

    Multiple identifiers may refer to one entity.

    One label may refer to multiple different entities.

    Entity equivalence requires supporting identity evidence.

    Classes and individual entities must remain distinct.

    Properties may change without changing entity identity.

    State-dependent assertions should preserve temporal context.

    Provenance should be retained for identity and relationship claims.

    Duplicate records must not automatically be merged.

INFERENCE_RULES
    IF
        Identifier uniquely resolves to Entity within defined namespace
    THEN
        infer
            Identifier denotes Entity

    IF
        Entity satisfies class membership criteria
    THEN
        infer_possible
            Entity instance_of Class

    IF
        Two records share identifier
    AND
        namespace and identity conditions match
    THEN
        infer_possible
            Same Entity

    IF
        Two records share only a name or label
    THEN
        DO_NOT_AUTOMATICALLY_INFER
            Same Entity

    IF
        Entity property changes over time
    THEN
        preserve
            Entity Identity
        AND
            update
                State or Property Value

    IF
        Strong evidence shows two identifiers refer to same entity
    THEN
        infer_possible
            Entity Equivalence

    IF
        Identity evidence conflicts
    THEN
        preserve
            Separate Entity Candidates
        AND
            trigger
                Entity Resolution Review

    Critical Distinction
        An entity is the distinguishable thing being represented; its
        identifiers, names and labels refer to it but are not the entity
        itself, and shared labels alone do not establish entity identity.

RECOMMENDED_AI_SUMMARY
    An Entity is a distinguishable thing represented within a semantic
    system with an identity, type, properties, states and relationships.
    Entities may have multiple identifiers and labels, while identical
    labels may refer to different entities. Reliable entity modelling
    therefore preserves context, provenance, temporal state and identity
    evidence, especially when resolving or merging entity records.
