  Versioning, status and change posture for the CDISC Library API and the standards it serves.

  note: >-
    Found in the cdisc.org footer ("CDISC Status"), not linked from the API documentation page. Statuspage
    exposes the standard unauthenticated JSON API (summary.json, status.json, incidents.json), so an agent can
    read component health without scraping.
versioning:
  interface_version: unversioned
  content_versioning: >-
    Versioning is of the STANDARD, not the interface. /mdr/sdtm/{version}, /mdr/adam/{version},
    /mdr/cdash, /mdr/ct/{packageDate}/codelists and /mdr/ars/packages/{package} each address a published,
    dated package that never changes once released.

  note: >-
    The CDISC Library Support knowledge base is served behind a Cloudflare bot challenge
    (cf-mitigated: challenge) — a human browser reaches it, our crawler does not. Treated as live-but-unreadable
    by machines, not as dead.

  note: >-
    No deprecation or sunset policy was found on any public CDISC surface, and no operation in any published
    contract carries `deprecated: true`. Superseded standards versions remain addressable at their own path
    rather than being retired, which is why no Deprecation pointer is emitted.
