  Peking University publishes no versioning policy, deprecation policy, SLA or status page
  for any of its machine-readable surfaces. What versioning exists is inherited from the
  protocols themselves — OAI-PMH declares protocolVersion 2.0 in every response, SAML
  metadata is versioned by validUntil/cacheDuration, and the repository REST API is the
  unversioned DSpace 5/6-era /rest tree with no version segment in the path. This is
  normal for a university and is recorded rather than treated as a gap to be filled.
versioning:
  scheme: protocol-declared
  detail: >-
    OAI-PMH responses carry <protocolVersion>2.0</protocolVersion>. The REST tree at
    /rest has no version segment and no version header was returned. The SCOW and
    CraneSched contracts published by github.com/PKUHPC are versioned by git tag and
    protobuf package, independently of any PKU-hosted deployment.

      TLS completes against PKU's own *.pku.edu.cn certificate and port 80 returns a 301
      to HTTPS, but no HTTPS response was ever delivered across seven attempts over 40
      minutes with browser user-agents, HTTP/1.1 and IPv4 forced. Other pku.edu.cn hosts
      answered normally in the same window, so this is specific to the host, not to us.
      It returned HTTP 200 to this catalog on 2026-06-03. Treated as unreadable from our
      vantage point, not as absent.
