summarizer_provider and summarizer_model carry the resolved summary provider
and model ids as they are, but the module docstring and the docs said every
categorical field comes from a closed set, and the field table did not list
them. A consumer reading that contract would treat them as bounded labels.
List both in the field table as free-form and narrow the closed-set claim to
the other categorical fields.
