  Searched the Discover Partner Product Portal, the Discover Developer Center and the Discover
  Global Network site for a versioning policy, a deprecation policy, a changelog, an SLA and a
  status page. Only the versioning scheme and the certificate-rotation cadence are published; the
  rest are genuinely absent from the public surface (each probe recorded below).

  scheme: uri-path
  current: mixed - v1 and v2 per service

retired_surfaces:
- id: stored-payment-tokens
  detail: The product page apis.yml pointed at (partner.discoverglobalnetwork.com/products/stored-payment-tokens)
    now soft-404s - it returns HTTP 200 with the generic portal title and no product body,
    identical to a nonsense slug. The product was renamed and now lives at
    /products/discover-stored-token-services.
  checked: '2026-09-06'
- id: dci-customer-service
  detail: /products/dci-customer-service soft-404s the same way; the live page is
    /products/diners-club-international-customer-service.
  checked: '2026-09-06'
- id: developer-center-rebuild
  detail: A rebuilt Discover Developer Center is visible at developertest2.discover.com
    (HTTP 200, "Browse APIs with interactive OpenAPI documentation"), fronting the same
    invitation-only sign-in. The live Developer Center at developer.discover.com is Drupal 10.
