+// Por que existe: o servidor Radar (1 GB RAM na Akamai) NUNCA clona nem instala
+// o OmniRoute; ele só baixa este JSON de uma URL estável. Antes o export vinha
+// do snapshot gravado no deploy, preso à máquina do operador. Este script roda
+// no CI do OmniRoute (que tem os módulos de catálogo + tsx), emite o export com
+// PROVENIÊNCIA e o workflow o publica como asset de release de URL fixa.
+//
+// Contrato do consumidor (`src/feed/exportSource.ts` no radar-server): exige
+// `budgets[]` não-vazio e lê `geradoEm`; chaves extras são ignoradas, então
+// `totais`, `registry` e `provenance` viajam junto sem quebrar retrocompat.
+//
+// Uso (precisa de tsx, pois lê .ts):
