additional property: How the Spin Works
  type: PropertyValue
  value: The framing relies entirely on lexical weight ('Fails') and brand association (Anthropic, Claude Opus) to imply gravity, while stripping away every element — methodology, actor, metric, evidence — that would allow validation or contextualization. The tension lies between the definitive tone of the claim and the total absence of anchoring proof or specification.
