QE is advised to consume stage IIBs from registry-proxy.engineering.redhat.com/rh-osbs registry like registry-proxy.engineering.redhat.com/rh-osbs/iib:1086961. This number is automatically generated, and we can't control that as other teams push to that registry, and this number is increased by each push...

To make things easier for QE we can create a new Konflux FBC stage pipeline that will include a new Tekton Task to mirror the newly created IIB to a fixed IIB, e.g., quay.io/redhat-user-workloads/rhwa-tenant/rhwa-fbc/rhwa-fbc-420:latest
