OpenShift enforces immutability at two distinct levels: individual resource fields (Route host, IngressController domain, IngressClass controller, CSIDriver attachRequired) are locked after creation, while platform-wide decisions (FIPS, CPU partitioning, network plugin) are locked at install time — creating a layered immutability model where some things can never change and others freeze on first write.
depth-2 — immutability operates at both the resource field level and the cluster-wide level
