upsert_type
Create or update a type and its fields. Use a singular key and label for one record; optional collection_label overrides the automatically pluralized list name (for example label: "Person", collection_label: "People"). Providing fields replaces the type's field list; omitting fields leaves existing fields unchanged. Add or change one field with upsert_field. fields is an array of {key, type, label, ...} or a map of key → field. Enum fields can use presentation: "badge" and explicit value_semantics; number fields can use presentation: "rating". Reference fields need target. expose: true stores the type on the account space so every app shares its records. Omit expose (or false) for app-only types. Example: upsert_type({ key: "person", label: "Person", collection_label: "People", expose: true, fields: [{ key: "name", type: "text", required: true }] }).
