Artefato oficial por unidade (município e ZE de Salvador): TSE 2026 presidente por seção + Solla 2026 e a fatia de 2022 da análise 2º turno; cada número validado contra o baseline TSE e os totais da BA pinados (pnpm build:second-round). O relatório ganha a seção "2º turno no município (Lula × Flávio)" com X₁/X₂ pela mesma fórmula do /potencial, o papel determinístico da cidade (prioridade/mobilizacao/defesa/expansao) e o novo item de pesquisa segundo_turno (movimento local com fonte); a seção fica fora da página 1 porque é determinística e a página 1 falha fechada por medição.
