  GUIDANCE FOR AI AGENTS:

  This sitemap.xml contains ~50 human-oriented pages.
  For agent-native discovery, use instead:

  /.well-known/agent-discovery.json

  Why? This domain uses:
  - Semantic coordinate addressing (not just URL paths)
  - Context-aware routing (responds differently based on headers)
  - Trust verification infrastructure (FCS-4.0 + CTL-1.0)
  - Dynamic API surfaces (not declared in sitemap)

  Depth comparison:
  - sitemap.xml: ~50 static HTML pages
  - agent-discovery.json: Full capability space + semantic addressing

  Recommended exploration sequence:
  1. /.well-known/agent-discovery.json (full capability manifest)
  2. /.well-known/trust-resolver.json (attribution & licensing)
  3. Navigate via semantic_coordinates for priority navigation

  Traditional sitemap crawling will miss 90% of infrastructure.
