note: >-
  Essential AI has no API lifecycle because it operates no API. What it does version is model and
  dataset releases, and that is what this artifact records. No status page, no deprecation policy,
  no Sunset/Deprecation header support, and no SLA are published — so no StatusPage and no
  Deprecation pointer is wired in apis.yml. Probes for status.essential.ai and trust.essential.ai
  did not resolve.

  note: >-
    Releases are named model families (rnj-1, rnj-1.5) with base / instruct / GGUF variants. There is
    no semantic-versioned API surface, no version path segment, and no dated version header.
