 # Página inicial e menus agrupados
 
+**Reposição de visibilidade da Contabilidade, 29/10/2026:** a entrada não tinha sido eliminada: o agrupamento horizontal colocara o grupo accounting dentro de Financeiro. A pedido da Tempo, Contabilidade volta a assunto principal, com dropdown próprio, preservando os oito destinos e os mesmos direitos. A ordem passa a Início, Comercial, Compras, Stock, Oficinas, Financeiro, Contabilidade, Configuração. Sem alteração de dados ou concessões. O check existente passa a manter inventário independente dos onze grupos, dos oito destinos contabilísticos e dos assuntos principais; cobre company.view e os dois direitos contabilísticos isolados, além da ausência de direitos. O comando build executa esse check antes do Vite, interrompendo a compilação perante regressão; não depende de hooks npm opcionais. Novas alterações devem actualizar explicitamente o inventário apenas quando o âmbito aprovado mudar. Esta guarda detecta remoção/agrupamento indevido conhecido, não substitui revisão visual ou prova no destino publicado. Prova HTTP da instância 8002 verifica também Contabilidade separada para as cinco funções sintéticas existentes. Sem publicação ou checkpoint.
+
+**Conferência da instância em execução, 29/10/2026:** após «continua a executar», scripts/navigation-live-check.mjs verificou as cinco funções sintéticas já existentes (proprietário, preparador, validador, técnico e verificador) por entrada/sessão/saída em 8002. Compras e Stock surgem separados nos cinco conjuntos efectivos de concessões; todos os destinos visíveis têm componente registado e não há IDs duplicados. A aplicação serve o bundle actual com purchasing_home, não apenas código-fonte local não compilado. Prova sanitizada em docs/proofs/navigation-live.json. Sem novas contas, alteração de concessões ou comandos de negócio. Conferência HTTP e renderização estática; não prova interactiva em navegador.
+
 **Reposição da visibilidade de Compras, 29/10/2026:** após separar Stock, o contexto sem direitos purchasing_budget/supplier_payables ficava sem itens no grupo Compras, ocultado pelo filtro de grupos vazios. A junção anterior permanecia visível pelos itens de Stock; nenhuma concessão ou dado tinha sido removido. Acrescentada Área de Compras informativa com company.view, sem acesso operacional implícito; preservadas as opções de orçamento/obrigações para os contextos autorizados. PurchasingHome.jsx distingue a área SGF da aplicação autónoma e não afirma incorporação integral. Regressão reproduz company.view sem direitos de Compras, confirma Compras/Stock separados e conserva filtros por unidade; build aprovado. Sem alteração de acessos ou dados.
 
 **Ajuste posterior, 29/10/2026:** Compras e Stock separados em dropdowns próprios. Ordem actual: Início, Comercial, Compras, Stock, Oficinas, Financeiro, Configuração. Fonte do menu principal aumentada de 0,87 para 1 rem; itens de submenu de 0,85 para 0,95 rem; fonte móvel de 0,78 para 0,9 rem. Mantidos destinos/permissões e dropdowns. Check de navegação e build aprovados; sem nova revisão visual.

+# Pagamentos e afectações sintéticos — entrega técnica, 29/10/2026
+
+Implementado o incremento seguinte às obrigações, nas duas composições, com uma única implementação financeira. Disponível apenas nas demonstrações isoladas: Compras <http://127.0.0.1:8005/demo> e SGF <http://127.0.0.1:8006/demo>. Seleccionar preparação, validação ou consulta; reconhecer primeiro a obrigação existente, com outra identidade, e seguir a ligação «Pagamentos e afectações». Não é uma autorização de utilização real nem aceitação da entrega.
+
+## Responsabilidade e código
+
+O código comum reside em `packages/payables/src/SupplierSettlements.php`, `SettlementSchema.php`, `SettlementHttp.php` e `ui/settlements.php`. Carregamento e apresentação em `bootstrap.php` e `src/Workspace.php`. `src/Payables.php` conserva a responsabilidade única pelo saldo: principal menos histórico confirmado existente e afectações novas confirmadas. Não se escrevem pagamentos externos legados para representar novamente o mesmo facto.
+
+Os adaptadores são `app/Modules/Purchasing/SupplierPaymentsController.php` no SGF e `app/Http/Controllers/SupplierPaymentsController.php` em Compras, apoiados nos respectivos `SupplierPayables.php`. Contexto, pessoa, organização e direitos são revalidados no servidor pelos adaptadores existentes; o motor recebe contexto explícito. Rotas em `routes/web.php` de cada aplicação. A página anterior de obrigações apresenta a ligação quando disponível. No SGF, `resources/js/WorkspaceNavigation.jsx` e `app.jsx` incluem a entrada; nenhuma concessão real foi adicionada.
+
+Não se equiparam tenant, empresa e unidade. Referências factuais são únicas dentro da empresa, mesmo entre unidades; a consulta e execução continuam limitadas pelo contexto autorizado. Não há dependência de vendas ou de um SGF remoto.
+
+## Percurso e montantes
+
+1. A obrigação reconhecida mantém 10 000 MZN de base, imposto documental de 1 600 e principal de **11 600 MZN**, sem recálculo fiscal.
+2. Preparação propõe um pagamento sintético de **4 000 MZN** com data factual e referências artificiais de facto/evidência `SIM-…`.
+3. Outra pessoa confirma com motivo e referência de evidência. O saldo da obrigação continua **11 600 MZN**; o pagamento confirmado tem **4 000 MZN por afectar**.
+4. Preparação propõe a afectação de 4 000 MZN à obrigação; outra pessoa confirma. Saldo **7 600 MZN**, por afectar zero. Origem, versão, decisões e histórico permanecem consultáveis.
+
+O vencimento continua desconhecido, atraso indeterminado e dias de atraso sem valor. A data factual do pagamento não preenche o vencimento. Montantes são cadeias decimais convertidas exactamente em cêntimos inteiros, sem floats ou arredondamento novo. Não houve substituição ou actualização de dependências.
+
+Pagamento proposto, confirmação e afectação são acontecimentos distintos. Rejeições não alteram dívida. Há afectações parciais, vários pagamentos por obrigação e um pagamento distribuído por vários documentos compatíveis. Excesso fica por afectar. Referências estáveis e conteúdo normalizado impedem duplicações por novas chaves, versões ou pedidos simultâneos; incompatibilidades geram conflito. Comandos, decisões, movimentos, auditoria e eventos/outbox são atómicos e duráveis. A revogação e a separação por actor e pessoa são verificadas também após espera pelo bloqueio.
+
+## Provas e alcance
+
+- `docs/proofs/supplier-settlements.json`: ambas as composições aprovadas, mesmo SHA-256 comum `156bd40f3080de66a73c0befd975990e9d7010c2a232a86d751d4db3af4fae93`. Factura realmente conferida pelo percurso existente de Compras; sequência 11 600 → confirmação sem abatimento → afectação → 7 600, com vencimento/dias nulos.
+- Repetição, referências/evidências duplicadas, conteúdo incompatível, insuficiência, rejeição, identidade/pessoa, isolamento, versão alterada, informação insuficiente, revogação, imutabilidade, falha injectada e recuperação aprovados. Doze corridas PostgreSQL entre processos, com esperas de bloqueio observadas; apenas um efeito por facto.
+- A prova multidocumento usa um adaptador de origem sintético explícito do mesmo núcleo: dois documentos liquidados, terceiro de outro fornecedor intacto, excesso de 400 MZN por afectar e duplicação entre unidades recusada. Não equivale a outro percurso completo de facturas na interface de cada host.
+- Regressões anteriores de obrigação e histórico aprovadas (`payables-http.json`, `payables-history.json`). Compras: **526 testes aprovados, 2 ignorados, 4 383 asserções**, SQLite em memória. Ignorados preexistentes: `users with two factor enabled are redirected to two factor challenge` e `security page is displayed`. Cobertura MFA permanece pendente; não são testes do efeito monetário, comprovado separadamente.
+- Builds de SGF e Compras, TypeScript de Compras, PHPStan da aplicação e das novas classes comuns e Pint aprovados. JavaScript da interface conferido sintacticamente.
+- `supplier-settlements-demo-access.json`: páginas/API e ligação das obrigações verificadas por HTTP/HTML nas três funções de cada demonstração. Sem comandos monetários nessas bases. **Não foi realizada revisão visual nem ensaio manual da equipa.** A prova do adaptador não substitui essa revisão.
+
+Automação: `scripts/payables-demo.ps1 proof -Settlements`, `settlements-http-proof.mjs`, `settlements-probe.php`. Bases e identidades de prova descartáveis, separadas das demonstrações e bases habituais. A revisão do navegador continua pendente; não se contornou o bloqueio da ferramenta.
+
+## Habilitação e preservação
+
+`scripts/settlements-install.php` instala nove tabelas `ps_*`, com restrições e triggers imutáveis, apenas após guarda efectiva de base QA local. Em cada demonstração foram adicionados sete direitos sintéticos às três identidades existentes, sem criar contas, documentos ou pagamentos. `settlements-demo-state.php` e os recibos `supplier-settlements-demo-compras.json` / `supplier-settlements-demo-sgf.json` comprovam por hashes a preservação dos documentos, histórico, contas e acessos anteriores. A demonstração orçamental não foi alterada.
+
+Estas tabelas **não constituem uma migração aplicada a desenvolvimento ou produção**. O instalador está limitado ao ensaio. Uma futura disponibilização fora de QA exige migração própria, contexto operacional, permissões, backup/restauro e tratamento aprovado dos históricos. Nenhuma base habitual, acesso real, dependência, publicação ou push foi alterado neste incremento.
+
+## Limites e próximos passos
+
+- Novos pagamentos sobre obrigações provenientes de importação histórica são recusados neste recorte. O circuito de confirmação/rejeição dos pendentes importados continua separado e preservado; não se incorporam liquidações antigas como dívida integral.
+- Uma ligação pagamento/obrigação é imutável e única. Aumentar posteriormente essa mesma ligação ou reverter uma confirmação exige um futuro percurso explícito de correcção; não está entregue. Outros pagamentos podem afectar a mesma obrigação.
+- Não há execução de banco/caixa, reconciliação, reembolsos, crédito automático, cobranças, documento fiscal/PDF, contabilidade, stock ou efeitos orçamentais adicionais. Outbox durável não significa ligação bancária ou contabilística entregue.
+- Fazer o ensaio visual curto nas duas demonstrações e recolher dificuldades da equipa. Depois decidir aceitação e eventual checkpoint exclusivamente local. Não foi criado checkpoint de encerramento.
+
+Esta entrega complementa [obrigações a fornecedores](SUPPLIER_PAYABLE_DELIVERY.md); não substitui as aceitações e limitações anteriores.
