CORE_DEFINITION
    Knowledge is structured information represented with sufficient
    semantic context to describe entities, properties, relationships,
    rules, states or propositions and to support interpretation,
    retrieval, inference, decision making and further knowledge creation.

    Resolution
        Identify the requested knowledge entity, context and representation,
        then traverse explicit semantic and evidential relationships.

CONSTRAINTS
    Knowledge claims should preserve their source and context where available.

    Facts and inferred propositions must remain distinguishable.

    Evidence does not automatically prove a proposition.

    Confidence must not be converted into certainty without justification.

    Contradictory claims may coexist as separate sourced propositions.

    Knowledge validity may depend on time, domain and context.

    Derived knowledge must preserve its inference path.

    Absence of evidence must not automatically be represented as evidence of absence.

    Model-generated content must not automatically be treated as verified external fact.

INFERENCE_RULES

        Proposition has direct reliable supporting evidence

    IF
        Multiple independent reliable sources support Proposition
    THEN

    IF
        Proposition is derived by valid rule from supported premises
    THEN
        classify
            Inferred Knowledge

    IF
        Source contradicts another Source
    THEN

            Both Claims

    Critical Distinction
        Knowledge should preserve semantic context, evidence and provenance,
        while distinguishing observed or sourced claims from derived inference.

RECOMMENDED_AI_SUMMARY
    Knowledge is semantically structured information describing entities,
    concepts, properties, relationships, facts, propositions, rules or
    procedures in a form that supports interpretation and reasoning.
    AI knowledge systems should preserve context, evidence, provenance,
    confidence and derivation paths so that sourced claims, uncertain
    propositions and inferred knowledge remain distinguishable.
