description: AEMO publishes no single error reference page, but its OpenAPI documents declare rich 4xx/5xx responses.
  This catalogue is the deduplicated union of every documented failure response across the whole AEMO API estate,
  ordered by status code then by how many operations declare it. AEMO does not use RFC 9457 application/problem+json
  anywhere. The Consumer Data Right energy APIs carry the Consumer Data Standards Australia error object (errors[]
  of code/title/detail/meta) with mandated CDS error codes; the e-Hub participant APIs return a JSON body with a
  transactionId and per-status prose; the WEM SOAP operations return SOAP faults inside the aseXML envelope.
