  Versioning and lifecycle posture for Cynergy Bank's OBIE Read/Write interface,
  derived from the harvested standard specs and the review. Version cadence is
  governed by OBIE (Open Banking Limited) release management, which the ASPSP
  tracks; Cynergy does not publish an independent per-endpoint deprecation policy
  or a public status page, and none should be invented.
versioning:
  scheme: uri-path
  current: v4.0.1
  path_segment: /open-banking/v4.0/{aisp|pisp|cbpii}
  governed_by: Open Banking Limited (OBIE) Read/Write API Standard release management
  history_note: >-
    Third-party references (OpenBankingTracker, Enable Banking) record historical
    conformance at OBIE Read/Write v3.0/v3.1; harvested specs are v4.0.1.
deprecation:
  policy_url: null
  sunset_header: null
  note: >-
    OBIE release management defines version deprecation and migration windows at
    the standard level; Cynergy does not publish a bank-specific deprecation
    policy page. No Sunset/Deprecation header support confirmed on the (mTLS-gated)
    production endpoints.
sla:
  url: null
  uptime_target: null
  note: >-
    PSD2 requires ASPSPs to publish quarterly availability/performance stats for
    the dedicated interface, but no public machine-readable SLA/availability
    endpoint was confirmed.
