notes: >-
  SVB (First Citizens) versions its commercial banking APIs in the URI path
  (v1, v2, v2.1) and publishes migration guides when a major version supersedes
  a prior one. Live probing confirms multiple concurrent ACH versions (1.3, 2.1,
  2.4) served side by side, evidencing a deprecation-with-migration lifecycle:
  older major versions remain reachable while partners migrate per the guide.
  No public status page or SLA document was found (status.svb.com does not
  resolve; developer.svb.com/status returns only the SPA shell).
