Review Comment: The comment says Jackson applies the *case-class* default for missing `disallowMultiInputs`, but `PortDescription.disallowMultiInputs` has no constructor default (see `PortDescriptor.scala`). This is misleading; the behavior here is that deserialization tolerates the missing boolean and results in `false` (e.g., via Jackson/NoCtorDeser defaulting). ########## common/workflow-operator/src/test/scala/org/apache/texera/amber/operator/PortDescriptorSpec.scala: ########## @@ -0,0 +1,234 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one + * or more contributor license agreements.

Review Comment: This comment refers to a “Missing-field default” for `disallowMultiInputs`. Since the case class doesn't define a default value for this parameter, it’s clearer to describe the observed deserialization behavior (missing boolean becomes `false`) without implying a Scala constructor default. -- This is an automated message from the Apache Git Service.
