+### 2026-08-11 03:00 — Radar de Conformidade: validação por CNPJ (1.2.0)
+
+- **Tempo:** ~30 min
+- **Prompt:** "em documentos, crie uma funcionalidade de validar conformidade" (spec: Obsidian
+  18 - Radar de Conformidade — metodologia do score + fontes de dados testadas em 11/08)
+- **Mudanças:** módulo `radar`: `RadarLookupService` (Receita em cadeia BrasilAPI→minhareceita→CNPJá,
+  QSA reduzido a contagem por LGPD; repasse da ANP com decode ISO-8859-1, falha degrada para
+  `available:false`); `RadarScoreService` (motor de 17 itens/7 esferas, R1–R7, teto por gargalo,
+  três números — espelho do frontend); entity+migration `radar_assessment` (única por
+  programa+loja+CNPJ, respostas em jsonb, diagnóstico sempre recalculado); controller
+  `/radar/company|anp|assessments`. 21 testes novos (83 no total).
+- **Artefatos:** branch `feat/compliance-radar`

 Formato baseado em [Keep a Changelog](https://keepachangelog.com/en/1.0.0/); versionamento semântico.
 
+## [1.2.0] - 2026-08-11
+
+### Added
+- **Radar de Conformidade** (`/radar/*`): validação de conformidade por CNPJ. `GET /radar/company/:cnpj`
+  consulta a Receita Federal em cadeia de fallback (BrasilAPI → minhareceita.org → CNPJá Open) e
+  normaliza para um shape único — o QSA é reduzido à contagem (LGPD). `GET /radar/anp/:cnpj` repassa a
+  API de revendedores da ANP (sem CORS na origem) com decode ISO-8859-1; falha degrada para
+  `available: false`, nunca erro. `GET/PUT /radar/assessments/:cnpj` guarda a autoavaliação dos 17
+  itens por (programa, loja, CNPJ) e devolve o diagnóstico recalculado: score declarado, score
+  verificado, índice de confiança, faixa A–E, teto por gargalo (documento impeditivo), pendências
+  ordenadas por ganho e calendário de vencimentos. Motor espelho do frontend (regras R1–R7 da
+  metodologia). Migration `radar_assessment` com up/down simétricos e idempotentes.
+
