Probed 2026-08-07 against the 2026 vintage: 30,752 disclosed positions over 648 issuers. After the three admission rules (PJ only, real 14-digit CNPJ, direct holdings only) 1,638 shareholding edges land, 1,635 of them carrying the filer's own percentage - the first real stake sizes the platform holds, since the Receita QSA roster publishes none. 66 issuers match a strata entity cluster and those clusters hold 3,354 assets, led by Vale (1,256), Votorantim Cimentos (704), Companhia Brasileira de Aluminio (416) and Ferbasa (205). Vale resolves to PREVI 7.016%, Mitsui 6.45% and the Ministerio da Economia; BlackRock (6.708%) and Capital World (5.129%) are named by CVM but carry no Brazilian register number and are therefore unkeyable rather than name-matched.
