additional property: How the Spin Works
  type: PropertyValue
  value: Combines virtue signaling ('safety', 'responsibility') with strategic ambiguity ('hidden', 'no technical details') to elevate intent over implementation; the framing makes the watermark feel ethically necessary and technically sound despite zero evidence of real-world efficacy, fairness, or user alignment.
