  https://home.quakerhoughton.com/wp-json/ (namespace index), the two served OpenAPI documents,
  and the live 400 missing_experimental_endpoint_acknowledgement response on tec/v1
description: >-
  Lifecycle posture for the machine surfaces on home.quakerhoughton.com. Quaker Houghton publishes
  no versioning policy, deprecation policy, SLA, status page or changelog of its own; the only
  lifecycle facts available are the ones the WordPress REST index and the plugin contracts state
  about themselves. Two generations of the same Events Calendar API coexist: the stable
  tribe/events/v1 namespace and the experimental tec/v1 namespace that the plugin gates behind an
  acknowledgement header until it is declared stable.
versioning:
  scheme: URL path namespace (/wp-json/<namespace>/v1)
  current:
  - namespace: tribe/events/v1
    status: stable
    contract: https://home.quakerhoughton.com/wp-json/tribe/events/v1/doc
  - namespace: tec/v1
    status: experimental
    contract: https://home.quakerhoughton.com/wp-json/tec/v1/docs
    gate: Data endpoints answer 400 missing_experimental_endpoint_acknowledgement until the caller opts in with the plugin's acknowledgement header.
