  Permutive serves an A2A Agent Card from its own documentation host,
  docs.permutive.com. The card describes the documentation agent surface (a
  single "Permutive" skill pointing at a provider-published Agent Skill file),
  not the audience-intelligence MCP server, which is invitation-only. The card
  was fetched anonymously and is stored verbatim; nothing here was authored on
  Permutive's behalf.

  deviation_notes: >-
    The card declares transports under `supportedInterfaces` rather than the A2A
    1.0.0 `additionalInterfaces` field, and reports protocolVersion as "0.3"
    rather than a full semantic version such as "0.3.0". All three hard
    structural checks pass.
