Submit an ISO 20022 admi.004 System Event Notification announcing a Direct Participant IPS's own downtime (EvtCd one of PIDN, SIDN, UIDN, EIDN). Nexus validates the message schema synchronously and returns 202 Accepted, then processes the body asynchronously. Any post-202 rejection is delivered out-of-band as an admi.002 to the IPS's admi.002 endpoint resolved from CAP reference data. Transport security requires mutual TLS: Nexus validates the caller's client certificate against the IPS certificate registered in CAP; the IPS identity is taken from that certificate, so no response endpoint is supplied on the request.
