"""Reference Data Registry (Missão 5, Fase 1): the NEW admin-approved ingestion workflow, separate
from central/app/datasets/service.py's existing auto-activate methods (untouched, still used by the
9 pre-existing dataset kinds). A dataset registered here lands as DRAFT and only becomes VIGENTE
(superseding the previous VIGENTE of the same kind) after an explicit ADMIN approval of the diff -
"Nenhuma versão de dataset vira 'vigente' sem aprovação ADMIN do diff" (mission rule).
