Subset: mvp¶
Fields the first production release extracts and stores. Membership is chosen by hand, field by field, by adding in_subset: [mvp] to an attribute. Identifiers and type designators are always included and are never marked.
An attribute is the only thing marked. A class has no mark of its own: it survives into the MVP when a marked attribute's range points at it, so leaving every attribute of a class unmarked is how that whole entity is dropped.
Orthogonal to how a field gets filled (deterministic and model_extracted below) and to the review urgency in storage-parameter-priorities.yaml. A field can be deterministic and still be outside the MVP, or low priority and inside it, so the axes never collapse into one.
