The readOnly field on a ApiKey record in Skarn Suite (the platform auth hub: SSO, tenancy, billing, entitlements, internal event bus) stores a specific piece of the data; it holds the api key read only value for this ApiKey record, one of the real fields the workflow reads and updates during normal operations. In everyday use this is part of how ApiKey records are created, displayed, validated, and reported, and it is grounded strictly in the real schema fact ApiKey.readOnly: Boolean.
