source: live probes of /.well-known/* across every Decart host in apis.yml
description: 'Discovery surface probe. Decart serves a single well-known document
  family, and it is on the documentation host rather than the API host: an A2A agent
  card plus the agent skill that card links to. No security.txt, no OAuth/OIDC discovery,
  no api-catalog, and no ai-plugin.json exists on any host. Absence is recorded data,
  not a gap in probing.'
