Every 404 below is a real HTTP 404 with an HTML SPA error body, not a soft-200; a negative-control path also 404d on both hosts. Extra rows beyond the closed core list were probed only because robots.txt, llms.txt and the ai-catalog name them explicitly — no glob was used. No OAuth/OIDC discovery document exists: the provider states MCP and A2A discovery are anonymous and the REST surface uses server-issued bearer machine credentials, so the RFC 9728 / RFC 8414 absences are consistent with its stated auth model.' path_echo_control: passed hit_count: 11 hosts: - host: https://dant3.net role: website + api + mcp + a2a documents: - path: /.well-known/security.txt status: 200 type: text/plain file: dant3-net-security.txt - path: /.well-known/openid-configuration status: 404 type: text/html note: SPA 404 page (HTTP 404, HTML body) - path: /.well-known/oauth-authorization-server status: 404 type: text/html note: SPA 404 page (HTTP 404, HTML body) - path: /.well-known/oauth-protected-resource status: 404 type: text/html note: SPA 404 page (HTTP 404, HTML body) - path: /.well-known/api-catalog status: 404 type: text/html note: SPA 404 page (HTTP 404, HTML body) - path: /.well-known/ai-plugin.json status: 404 type: text/html note: SPA 404 page (HTTP 404, HTML body) - path: /.well-known/ucp.json status: 404 type: text/html note: SPA 404 page (HTTP 404, HTML body) - path: /.well-known/acp.json status: 404 type: text/html note: SPA 404 page (HTTP 404, HTML body) - path: /.well-known/aauth-resource.json status: 404 type: text/html note: SPA 404 page (HTTP 404, HTML body) - path: /.well-known/apis.json status: 404 type: text/html note: SPA 404 page (HTTP 404, HTML body) - path: /apis.json status: 404 type: text/html note: SPA 404 page (HTTP 404, HTML body) - path: /apis.yml status: 404 type: text/html note: SPA 404 page (HTTP 404, HTML body) - path: /.well-known/agent-card.json status: 200 type: application/json file: dant3-net-agent-card.json note: A2A 1.0 Agent Card;
