## Coverage notes

Brazil has **not yet published a closed federal OIV-equivalent registry**
analogous to Chile's ANCI Res Ex 87 (915 operators). This dataset
combines apex operators from sectoral regulators (BCB, ANATEL, ANEEL,
ANS, ANP, ANA, ANTAQ, ANTT, ANAC), large publicly-listed groups
(B3/CVM filings), and federal autarchies. Sub-national operators
(regional water/power utilities, state data-processing companies) are
under-represented in this v0 dataset; PR contributions welcome.
