PURPOSE
    Define a formal AI-readable ontology for Long-Term Memory in artificial
    intelligence, including persistent memory items, durable storage,
    episodic memory, semantic memory, procedural memory, encoding,
    indexing, retrieval, consolidation, updates, versioning, forgetting,
    provenance, confidence, temporal validity, access control and recursive
    persistent-memory management.

CORE_DEFINITION
    Long-Term Memory is a persistent computational memory system that
    retains information beyond the immediate active context or current
    reasoning episode so that relevant prior knowledge, events, procedures
    or state can be retrieved and reused in later interactions or tasks.

CONSTRAINTS
    Long-term memory and working memory must remain distinct.

    Persistence must not automatically be interpreted as permanent validity.

    Stored memories must not automatically be treated as verified truth.

    Retrieved memories must not automatically be treated as current facts.

    Provenance must remain associated with persistent memory.

    Temporal validity must remain represented.

    Memory versions and updates must remain distinguishable.

    Similarity-based retrieval must not automatically be interpreted as identity or factual equivalence.

    Access and privacy constraints must remain associated with persistent information.

    Forgetting or deletion must not be represented as complete unless the relevant storage system confirms it.

    Critical Distinction
        Long-term memory persists beyond immediate active context, but
        persistence does not establish permanent validity. Stored memories
        are not automatically verified truth, and retrieved memories must
        be checked for provenance, version and temporal relevance before use.

RECOMMENDED_AI_SUMMARY
    Long-Term Memory is persistent AI memory that retains information
    beyond the immediate active context so it can be reused in later tasks
    or interactions. It may store episodic, semantic, procedural,
    structured or vector-based representations and use indexes for
    retrieval. Reliable long-term memory preserves provenance, timestamps,
    versions, confidence, temporal validity and access controls while
    distinguishing persistence from permanent validity and remembered
    information from verified current evidence.
