additional property: How the Spin Works
  type: PropertyValue
  value: Combines authoritative venue attribution (Black Hat), named researcher credibility, and active-voice threat verbs ('hijack', 'spoof', 'exhaust') to foreground attacker agency. This makes the underlying architectural fragility — shared across vendors due to specification gaps or implementation shortcuts — feel like an external challenge rather than a systemic design liability, even though the claim centers on implementation behavior across 'independently developed' systems.
