Dataset scope

The integration filters and paginates the official DCP dataset for HIC, NHC, and MCO records. Each type is ingested separately, with its source status preserved.

Filter search by CT and a specific license_type when needed.
Verify a supplied credential number.
Use credential_kind to distinguish registration from license.

Production refresh

Connecticut source jobs are scheduled daily. Review source_updated_at and last_updated when available; confirm material decisions at DCP eLicense.
