+### Endpoint XHTTP compartilhado
+
+Na aba **Xray → Configuração Xray → Visual**, o cartão **Shared XHTTP endpoint** cria dois inbounds na mesma porta:
+
+- VLESS **ou** VMess em `/` (selecione um protocolo raiz);
+- SSH sobre XHTTP em `/ssh`, autenticado pelas contas SSH normais do painel.
+
+O listener HTTP interno escolhe o caminho mais específico, portanto `/ssh` é encaminhado ao servidor SSH antes do inbound raiz. Todos os inbounds na mesma porta devem usar a mesma opção TLS e o mesmo certificado. Esse recurso exige o modo **Internal native emulator**; o binário Xray externo não reconhece o protocolo `ssh` específico do DragonCore.
+
+Para configurações XHTTP antigas, carregue a configuração visual e clique em **Ativar SSH /ssh** no cartão VLESS/VMess existente. O painel preserva o inbound original, seus clientes, path, host, modo, opções avançadas e TLS; cria apenas o inbound SSH correspondente na mesma porta e salva/reinicia o Xray. Não é necessário recriar clientes ou o endpoint.
+
+A confirmação dessa migração é exibida dentro do próprio painel. Se a gravação falhar, o inbound SSH temporário é removido do rascunho e o inbound antigo permanece intacto, permitindo tentar novamente após corrigir o erro exibido.
+
+### Revendedores compatíveis com o painel PHP antigo
+
+A área **Revendedores** mantém o fluxo mais importante do DraconCore PHP, com autorização refeita no servidor:
+
+- cada revendedor gerencia apenas suas contas e seus sub-revendedores diretos;
+- o superadmin enxerga toda a hierarquia;
+- plano **Validade / slots** compartilha a cota entre a capacidade `max_connections` das contas SSH/Xray e os slots reservados aos sub-revendedores;
+- plano **Créditos** debita no cadastro e na renovação; o custo acompanha `max_connections`, com mínimo de uma conexão, e esse limite fica congelado após a criação;
+- contas de plano por crédito recebem 31 dias por cadastro ou renovação;
+- criação, edição, renovação, suspensão, reativação e exclusão de revendedores ficam registradas em auditoria;
+- suspensão bloqueia a árvore e remove os clientes Xray do runtime sem apagar seus metadados; a reativação restaura os clientes ainda válidos;
+- exclusão remove a árvore, suas contas SSH/Xray e devolve ao pai os créditos ainda não usados;
+- a cota considera todos os nós gerenciados, mesmo temporariamente desativados, para impedir liberação artificial de limite;
+- o estado de acesso é sincronizado com nós gerenciados sem copiar senha ou hash de login.
+
+Revendedores existentes são migrados automaticamente como contas principais no modo **Validade / slots**. Não é necessário recriá-los. Por segurança, as funções antigas de revelar senha em texto puro e de alterar a sessão para “entrar como revendedor” não foram copiadas.

+### Shared XHTTP endpoint
+
+In **Xray → Xray Config → Visual**, the **Shared XHTTP endpoint** card creates two inbounds on the same port:
+
+- VLESS **or** VMess on `/` (select one root protocol);
+- SSH over XHTTP on `/ssh`, authenticated by the panel's regular SSH accounts.
+
+The internal HTTP listener selects the most specific path, so `/ssh` reaches the SSH server before the root inbound. Every inbound sharing a port must use the same TLS setting and certificate. This feature requires **Internal native emulator** mode; the external Xray binary does not recognize DragonCore's custom `ssh` protocol.
+
+For older XHTTP configurations, load the visual configuration and click **Enable SSH /ssh** on the existing VLESS/VMess card. The panel preserves the original inbound, clients, path, host, mode, advanced options, and TLS; it only creates the matching SSH inbound on the same port and then saves/restarts Xray. There is no need to recreate clients or the endpoint.
+
+The migration confirmation is rendered inside the panel. If saving fails, the temporary SSH inbound is removed from the draft and the old inbound remains intact, so the operation can be retried after fixing the displayed error.
