def call

    payload = payload.clone if payload.is_a?(Hash)

    # Extract and remove guards option from options, default to true
    guards = options.delete(:guards)
    guards = true if guards.nil?

    # Extract and remove metadata option from options if present
    metadata = options.delete(:metadata)

    # Handle different calling patterns:
    # 1. command(value) or command(value, guards: false) - shorthand form with single value
    # 2. command({attr: value}) or command({attr: value}, guards: false) - hash form
    # 3. command(attr: value) - ALL kwargs are treated as payload (no options)
    # 4. command() - no arguments (for commands without payload)

    # If no positional argument was provided but kwargs were given (after removing guards/metadata),
    # treat all remaining kwargs as payload
    if payload.nil? && !options.empty?
