  Metro Bank developer portal + OBIE versioning policy; URI-path versions
  observed on the live host and in apis.yml baseURLs.
versioning:
  scheme: uri-path
  current:
    open_data: v2.3
    read_write: v3.1

  docs: https://developer.metrobankonline.co.uk/Overview
  policy: >-
    Versions follow the OBIE standard release train; ASPSPs adopt OBIE-published
    major/minor versions and run them at distinct /open-banking/vX.Y base paths.
deprecation:
  policy: >-
    Superseded OBIE versions are retired on the OBIE migration timetable;
    Metro Bank exposes multiple concurrent versions per path during transition.

  note: >-
    Availability and performance are reported under FCA/OBIE operational
    guidelines; Metro Bank publishes an FCA Account Metrics API for service-quality
    reporting rather than a public developer SLA page.
