  "title": "Brazil (Minas Gerais) Notice of Vehicle Sale (Comunicação de Venda)",
  "description": "The Departamento Estadual de Trânsito de Minas Gerais's (DETRAN-MG) 'Requerimento de Comunicação de Venda' — the seller-side notice a private vehicle owner in Minas Gerais files with DETRAN-MG after selling a vehicle, per art. 134 of the Código de Trânsito Brasileiro (CTB, Federal Law No. 9.503/1997). Filing this notice records the buyer's identity against the vehicle in DETRAN-MG's registry and releases the seller from civil/criminal liability for the vehicle from the sale date forward; it is distinct from the buyer's own follow-on step of bringing the notarized transfer document (CRV or ATPV-e) to a DETRAN-MG unit within 30 days to register the vehicle in their own name, which this document does not model (see VERIFICATION.md). Vehicle registration in Brazil is administered per state DETRAN, not federally, so this document is modelled as a subnational (BR-MG) schema, the same way this registry already classifies br/sp/jucesp/cnpj-registration-dbe and mx/semovi/alta-vehiculo-foraneo. DETRAN-MG's own online filing channel (protocolo.detran.mg.gov.br) requires an authenticated citizen login on every path tried; this document is instead derived directly from DETRAN-MG's own current, unauthenticated, directly downloadable PDF request form, cross-checked against an earlier edition of the same form and DETRAN-MG's own official explanatory booklet. GovSchema is independent and is not affiliated with, endorsed by, or operated by the Government of Brazil, the State of Minas Gerais, or DETRAN-MG.",

    "notes": "Source-derived reference schema closing the global DMV vertical's last open jurisdiction gap (CATALOG.md 'Known Gaps', Brazil). Fetched directly from detran.mg.gov.br (HTTP 200, application/pdf, no login/CAPTCHA/WAF); PDF metadata (Microsoft Word, CreationDate 2026-01-29) confirms this is a current edition. The form carries a genuine (non-scanned) text layer, extracted via pdfjs-dist@3.11.174 getTextContent() — doc.getFieldObjects() returned null and getAnnotations() returned an empty array, confirming no interactive AcroForm widgets, so every field here is a printed label plus a blank, read directly from the text layer. Cross-checked against an older edition of the same form (also fetched directly from detran.mg.gov.br, filename 'Requerimento.pdf', CreationDate 2022-05-24): field content and order are identical apart from the closing municipality/date block, confirming field stability across editions. DETRAN-MG's own live online filing wizard (protocolo.detran.mg.gov.br/veiculos/comunicacao-venda-veiculo/inserir-dados-responsavel) returns HTTP 302 to http://protocolo.detran.mg.gov.br/ssc/login/login on every path tried — an authenticated-citizen-login gate consistent with prior cycles' findings for DETRAN-SP (GOV-1483) and BR CNH (GOV-1400) — so this document was authored from the static PDF, not a live wizard walk. See VERIFICATION.md for the full sourcing method, the other Brazilian DMV candidates screened and rejected this cycle, and every disclosed interpretive judgment call."
