 * Sealed instance is read only form of model entity that contains seal-breaking actions such as opening its contents
 * to write actions using {@link InstanceEditor} or accepting mutations that create {@link EntityMutation} objects. All
 * seal breaking actions don't modify {@link SealedInstance} contents and only create new objects based on it.
 * This keeps this class immutable and thread safe.
