Multiple OpenShift resources enforce field immutability after creation — Route host, IngressController domain, and IngressClass controller cannot be changed post-creation — establishing a pattern where identity-defining fields are write-once to prevent runtime conflicts and maintain stable addressing.
Three independent immutable-field constraints form a write-once identity pattern
