Coverage and provenance
Sources contributing to this profile
Cross-source matches use exact identifiers or exact normalized names and do not by themselves prove identity.
Headline activity and concentration use DNCP adjudicaciones; source histories are kept separate and are never added across datasets.
This profile consolidates source keys within one country and role only through exact identifiers or an unambiguous normalized legal name. Currencies and unit scales remain separate; similar names are not assumed to be the same organization.
