Ask for a worked example on your own material, and the evidence needed to reproduce it.
We use “PDF parsing” only where a product mechanism or an evaluation method backs it up, and we say when the behaviour depends on how a deployment is configured.
Pick a real piece of work, agree what a good answer looks like, then go through the results together.
