    """
    Central intelligence artifact representing the current state of a runner.
    
    This object serves as the canonical interface between the pipeline and:
    - UI (Gradio)
    - Integrations (Strava / WhatsApp)
    - Observability analytics
    
    It aggregates derived signals without altering pipeline logic.
    Fields are raw values rather than translated text, allowing i18n
    at the edge (e.g. UI).
