x-rationale: 'OEAPI is a standard each institution implements on its own host, and the only server in the contract (https://demo01.eduapi.nl/v6,
  SURF demo) did not resolve on 2026-10-09. This overlay adds a templated implementer server, provenance metadata and agent
  read/write hints. It deliberately does NOT add securitySchemes: the spec tag `security` states that no global security is
  defined so the core stays neutral, and auth is chosen per implementation.'
