-- Drug (药品) archive kind: a new domain on the generic archive_kind framework
-- (see 0010). No new table — drug spec values live in product.attributes JSONB,
-- driven by the kind_field template below, plus a 'drug' category subtree.

-- Field template for the drug domain. field_type is constrained to
-- text/number/textarea/select/list by kind_field_type_chk. The `qualified`
-- fields are the identifying / regulatory essentials that count toward the
-- kind-aware completeness score.
