x-enrichment-note: '2026-09-23 local-v5 pass BLOCKED: after ~25 probes the host 85.215.231.137 began refusing TCP
  443 from our IP (connection refused for 40+ minutes). llms.txt was fetched (200) and saved verbatim; the OpenAPI
  3.1 spec it names at /openapi/agent-api.yaml was never fetched. Re-run slowly (one request every few seconds);
  pointers above come from the llms.txt and sitemap.xml and are unverified.'
