PURPOSE
    Define an AI-readable semantic ontology for a Knowledge Base,
    including facts, entities, concepts, relationships, rules, assertions,
    sources, provenance, confidence, retrieval, inference, validation,
    updates and recursive knowledge maintenance.

CORE_DEFINITION
    A Knowledge Base is an organised repository of represented knowledge
    containing facts, entities, concepts, relationships, rules, assertions
    or other structured information that can be stored, retrieved, queried,
    validated, updated and used for reasoning or decision support.

    Resolution
        Identify repository type, knowledge items, sources, rules,
        retrieval mechanisms and inference relationships.

CONSTRAINTS
    Stored information must not automatically be treated as verified knowledge.

    Asserted and inferred knowledge must remain distinguishable.

    Provenance should be retained where available.

    Confidence must not be treated as certainty.

    Contradictory knowledge items may coexist and should be explicitly represented.

    Knowledge validity may depend on time, domain and context.

    Updates should not silently destroy historically valid information
    when temporal versioning is relevant.

    Retrieval is distinct from reasoning.

    A generic database must not automatically be classified as a knowledge base.

INFERENCE_RULES
    IF
        Query matches stored knowledge item
    THEN
        retrieve
            Knowledge Item

    IF
        Rule applies to supported premises
    THEN
        derive
            Inferred Knowledge Item

    IF
        Knowledge Item has reliable source
    THEN
        increase_confidence_in
            Knowledge Item

    IF
        Multiple independent reliable sources support assertion
    THEN
        increase_confidence_in
            Assertion

    IF
        New assertion contradicts existing assertion
    THEN
        preserve
            Both Assertions
            Sources
            Provenance
            Confidence
        AND
            trigger
                Conflict Evaluation

    IF
        Knowledge Item is superseded by newer time-specific information
    THEN
        preserve
            Historical Version
        AND
            mark
                Current Version

    IF
        Information lacks evidence
    THEN

    Critical Distinction
        A knowledge base stores represented knowledge for retrieval and
        reasoning, but stored assertions must remain distinguishable from
        verified facts and from conclusions generated through inference.

RECOMMENDED_AI_SUMMARY
    A Knowledge Base is an organised repository of facts, entities,
    concepts, relationships, rules and assertions that computational
    systems can store, retrieve, query and reason over. Reliable knowledge
    bases preserve source, context, provenance, confidence and temporal
    validity, distinguish asserted from inferred knowledge and explicitly
    represent conflicts or superseded information rather than silently
    treating all stored content as verified fact.
