Official history identifies inherited reckoning and original research documents an independent eight-real account unit. Intervening regional stages remain qualified.

Inference C1211

The 1831 reform converted obligations and deposits payable in Brazilian copper into the local Uruguayan monetary system. Attribution to the Brazilian real is a qualified contributing account-conversion input, not an exclusive founding parent or a claim that circulated coins alone create ancestry.
