additional property: How the Spin Works
  type: PropertyValue
  value: Relies on the credibility halo of Hacker News as a venue for elite technical discourse, combined with precise jargon ('backchannel', 'arbitrary code execution') to imply authority — making the unverified claim feel more substantiated than it is, while the complete absence of supporting detail creates an accountability vacuum where scrutiny is discouraged by perceived consensus.
