PURPOSE
    Define a formal AI-readable ontology for Agent Communication,
    including agents, senders, recipients, messages, message content,
    performatives, protocols, channels, addressing, encoding, timestamps,
    acknowledgements, dialogue state, delivery, interpretation, trust,
    provenance, uncertainty, confidence and recursive communication
    validation.

CORE_DEFINITION
    Agent Communication is the structured exchange of messages or signals
    between autonomous or semi-autonomous agents in order to share
    information, request actions, coordinate behaviour, negotiate, report
    state or otherwise influence multi-agent interaction.

CONSTRAINTS
    Sender and recipient identities must remain explicit.

    Message identity must remain stable.

    Message content and performative must remain distinguishable.

    Protocol and protocol version must remain explicit where relevant.

    Message delivery must not automatically be interpreted as understanding.

    Message receipt must not automatically be interpreted as agreement.

    Acknowledgement must not automatically be interpreted as acceptance.

    Shared messages must not automatically be interpreted as shared beliefs.

    Message ordering and timestamps must remain represented where sequence matters.

    Provenance and uncertainty must remain preserved.

    Critical Distinction
        Agent communication records the exchange of messages between
        distinct agents. Message delivery does not guarantee understanding,
        receipt does not imply agreement, acknowledgement does not always
        mean acceptance and receiving the same information does not imply
        that multiple agents hold the same belief.

RECOMMENDED_AI_SUMMARY
    Agent Communication is the structured exchange of messages between AI
    agents for sharing information, requesting actions, coordinating tasks,
    negotiating or reporting state. Messages may include content,
    performatives, addressing, timestamps and acknowledgements and operate
    under explicit communication protocols. Reliable agent communication
    preserves sender and recipient identity, message ordering, protocol
    versions and provenance while distinguishing delivery from
    understanding, acknowledgement from acceptance and shared messages from
    shared beliefs.
