+# Implementando Basic Auth
+
+Para validar **todo o circuito com Basic Auth**, você precisa configurar três relações distintas:
+
+```text
+Cliente de teste
+   └─ Basic Auth A ─► Agent Gateway :8010
+                         └─ Basic Auth B ─► Agent Backend :8000
+                                                └─ Basic Auth C ─► MCP Gateway :8300
+```
+
+Há um detalhe importante: no pacote atual, a autenticação Basic já funciona para chamadas **de entrada**, mas os clientes internos ainda não enviam Basic Auth:
+
+* `Agent Gateway → Agent Backend` não envia credencial;
+* `Agent Backend → MCP Gateway` envia apenas Bearer Token.
+
+Portanto, para testar o circuito inteiro com Basic Auth, faça os dois pequenos ajustes de código descritos abaixo.
+
+---
+
+# 1. Preparar o ambiente
+
+Considere que o ZIP foi extraído em:
+
+```bash
+cd agent_framework_oci_authentication_v2_1
+```
+
+Crie um único ambiente virtual para facilitar o teste:
+
+```bash
+python -m venv .venv
+source .venv/bin/activate
+```
+
+No Windows PowerShell:
+
+```powershell
+python -m venv .venv
+.\.venv\Scripts\Activate.ps1
+```
+
+Instale o framework e as dependências dos três componentes:
+
+```bash
+pip install -U pip
+
+pip install -e ./libs/agent_framework
+
+pip install \
+  -r ./Tuning-Performance/Authentication/agent_template_backend_authentication/requirements.txt \
+  -r ./apps/agent_gateway/requirements.txt \
+  -r ./apps/mcp_gateway/requirements.txt
+```
+
+Confirme a importação:
+
+```bash
+python -c "from agent_framework.security import install_authentication; print('framework ok')"
+```
+
+---
+
+# 2. Criar três pares de Client ID e Secret
+
+Use credenciais diferentes para cada trecho. Para teste local:
+
+| Fluxo                   | Client ID            | Secret de teste             |
+| ----------------------- | -------------------- | --------------------------- |
+| Cliente → Agent Gateway | `tia-test`           | `TiaGateway-Test-2026!`     |
+| Agent Gateway → Backend | `agent-gateway-test` | `GatewayBackend-Test-2026!` |
+| Backend → MCP Gateway   | `agent-backend-test` | `BackendMcp-Test-2026!`     |
+
+Esses valores são apenas para ambiente local. Não os reutilize em produção.
+
+## Gerar os hashes
+
+O script está em:
+
+```text
+Tuning-Performance/Authentication/
+  agent_template_backend_authentication/
+    scripts/generate_secret_hash.py
+```
+
+Execute:
+
+```bash
+python Tuning-Performance/Authentication/agent_template_backend_authentication/scripts/generate_secret_hash.py \
+  --secret 'TiaGateway-Test-2026!'
+```
+
+Depois:
+
+```bash
+python Tuning-Performance/Authentication/agent_template_backend_authentication/scripts/generate_secret_hash.py \
+  --secret 'GatewayBackend-Test-2026!'
+```
+
+E:
+
+```bash
+python Tuning-Performance/Authentication/agent_template_backend_authentication/scripts/generate_secret_hash.py \
+  --secret 'BackendMcp-Test-2026!'
+```
+
+Você receberá três valores semelhantes a:
+
+```text
+pbkdf2_sha256:310000:<salt>:<digest>
+```
+
+Guarde-os temporariamente:
+
+```bash
+HASH_CLIENT_GATEWAY='pbkdf2_sha256:310000:...'
+HASH_GATEWAY_BACKEND='pbkdf2_sha256:310000:...'
+HASH_BACKEND_MCP='pbkdf2_sha256:310000:...'
+```
+
+O hash muda a cada execução porque o salt é aleatório. Isso é esperado.
+
+---
+
+# 3. Configurar o Agent Gateway
+
+Entre no diretório:
+
+```bash
+cd apps/agent_gateway
+```
+
+Copie o exemplo:
+
+```bash
+cp .env.example .env
+```
+
+Adicione ao final do `.env`:
+
+```env
+# Entrada: cliente/TIA -> Agent Gateway
+AGENT_GATEWAY_AUTH_ENABLED=true
+AGENT_GATEWAY_AUTH_MODE=basic
+AGENT_GATEWAY_AUTH_BASIC_CLIENT_ID=tia-test
+AGENT_GATEWAY_AUTH_BASIC_SECRET_HASH=COLE_AQUI_HASH_CLIENT_GATEWAY
+AGENT_GATEWAY_AUTH_BASIC_REALM=agent-gateway
+
+AGENT_GATEWAY_AUTH_PUBLIC_PATHS=/health,/docs,/openapi.json,/redoc
+AGENT_GATEWAY_AUTH_PUBLIC_PREFIXES=
+
+# Saída: Agent Gateway -> Agent Backend
+BACKEND_AUTH_MODE=basic
+BACKEND_AUTH_CLIENT_ID=agent-gateway-test
+BACKEND_AUTH_SECRET=GatewayBackend-Test-2026!
+```
+
+Não coloque aspas no `.env`:
+
+```env
+BACKEND_AUTH_SECRET=GatewayBackend-Test-2026!
+```
+
+O arquivo de backends já aponta o backend Contas para:
+
+```yaml
+contas:
+  url: http://localhost:8000
+```
+
+Arquivo:
+
+```text
+apps/agent_gateway/config/backends.yaml
+```
+
+Para este teste, mantenha apenas o backend `contas` ou force o backend no payload. Caso contrário, pedidos sobre ofertas e suporte podem ser roteados para portas em que nenhum backend está rodando.
+
+---
+
+# 4. Fazer o Agent Gateway enviar Basic Auth ao backend
+
+Abra:
+
+```text
+libs/agent_framework/src/agent_framework/global_supervisor/client.py
+```
+
+Substitua a classe `BackendClient` por uma versão que aceite autenticação Basic.
+
+No início do arquivo, adicione:
+
+```python
+import os
+```
+
+Altere o construtor:
+
+```python
+class BackendClient:
+    def __init__(
+        self,
+        timeout_seconds: float = 120.0,
+        basic_client_id: str | None = None,
+        basic_secret: str | None = None,
+    ):
+        self.timeout_seconds = timeout_seconds
+        self.basic_client_id = basic_client_id
+        self.basic_secret = basic_secret
+
+    def _auth(self) -> httpx.BasicAuth | None:
+        if self.basic_client_id and self.basic_secret:
+            return httpx.BasicAuth(
+                username=self.basic_client_id,
+                password=self.basic_secret,
+            )
+        return None
+```
+
+No método `call_message`, troque:
+
+```python
+resp = await client.post(url, json=payload)
+```
+
+por:
+
+```python
+resp = await client.post(
+    url,
+    json=payload,
+    auth=self._auth(),
+)
+```
+
+No método `health`, você pode manter `/health` público. Caso queira enviar autenticação também, use:
+
+```python
+resp = await client.get(url, auth=self._auth())
+```
+
+Agora abra:
+
+```text
+apps/agent_gateway/app/main.py
+```
+
+Adicione:
+
+```python
+import os
+```
+
+Troque:
+
+```python
+backend_client = BackendClient(
+    timeout_seconds=settings.BACKEND_TIMEOUT_SECONDS
+)
+```
+
+por:
+
+```python
+backend_client = BackendClient(
+    timeout_seconds=settings.BACKEND_TIMEOUT_SECONDS,
+    basic_client_id=os.getenv("BACKEND_AUTH_CLIENT_ID"),
+    basic_secret=os.getenv("BACKEND_AUTH_SECRET"),
+)
+```
+
+Isso implementa:
+
+```text
+Agent Gateway → Agent Backend
+Authorization: Basic base64(agent-gateway-test:GatewayBackend-Test-2026!)
+```
+
+---
+
+# 5. Configurar o Agent Backend autenticado
+
+Entre no diretório:
+
+```bash
+cd Tuning-Performance/Authentication/agent_template_backend_authentication
+```
+
+Copie o exemplo:
+
+```bash
+cp .env.example .env
+```
+
+Ajuste a seção de autenticação:
+
+```env
+# Entrada: Agent Gateway -> Agent Backend
+AGENT_AUTH_ENABLED=true
+AGENT_AUTH_MODE=basic
+AGENT_AUTH_BASIC_CLIENT_ID=agent-gateway-test
+AGENT_AUTH_BASIC_SECRET_HASH=COLE_AQUI_HASH_GATEWAY_BACKEND
+AGENT_AUTH_BASIC_REALM=agent-contas
+
+AGENT_AUTH_PUBLIC_PATHS=/health,/docs,/openapi.json,/redoc
+AGENT_AUTH_PUBLIC_PREFIXES=
+```
+
+Para usar o MCP Gateway:
+
+```env
+MCP_GATEWAY_ENABLED=true
+MCP_GATEWAY_URL=http://localhost:8300
+MCP_GATEWAY_TIMEOUT_SECONDS=60
+
+# Saída: Agent Backend -> MCP Gateway
+MCP_GATEWAY_AUTH_MODE=basic
+MCP_GATEWAY_BASIC_CLIENT_ID=agent-backend-test
+MCP_GATEWAY_BASIC_SECRET=BackendMcp-Test-2026!
+```
+
+Para evitar dependências externas durante o primeiro teste, configure também:
+
+```env
+LLM_PROVIDER=mock
+ENABLE_LANGFUSE=false
+ENABLE_ANALYTICS=false
+
+SESSION_REPOSITORY_PROVIDER=memory
+MEMORY_REPOSITORY_PROVIDER=memory
+CHECKPOINT_REPOSITORY_PROVIDER=memory
+CACHE_PROVIDER=memory
+USAGE_REPOSITORY_PROVIDER=memory
+```
+
+Os nomes exatos de alguns providers podem depender do arquivo de configuração atual do framework. Caso o `.env.example` já contenha valores locais ou mock, preserve-os.

+
+Abra:
+
+```text

+        "MCP_GATEWAY_BASIC_SECRET",
+        None,
+    ),
+)
+```
+
+Adicione estes campos em:
+
+```text
+libs/agent_framework/src/agent_framework/config/settings.py
+```
+
+Próximo das configurações existentes de MCP Gateway:
+
+```python
+MCP_GATEWAY_AUTH_MODE: str | None = None
+MCP_GATEWAY_BASIC_CLIENT_ID: str | None = None
+MCP_GATEWAY_BASIC_SECRET: str | None = None
+```
+
+Há também uma factory local em:
+
+```text
+Tuning-Performance/Authentication/
+  agent_template_backend_authentication/
+    app/mcp_gateway_client_factory.py
+```
+
+Ajuste para:
+
+```python
+from __future__ import annotations
+
+import os
+
+from agent_framework.gateways import MCPGatewayClient
+
+
+def build_mcp_gateway_client() -> MCPGatewayClient | None:
+    if os.getenv("MCP_GATEWAY_ENABLED", "true").lower() != "true":
+        return None
+
+    return MCPGatewayClient(
+        base_url=os.getenv(
+            "MCP_GATEWAY_URL",
+            "http://localhost:8300",
+        ),
+        token=os.getenv("MCP_GATEWAY_TOKEN") or None,
+        timeout_seconds=int(
+            os.getenv("MCP_GATEWAY_TIMEOUT_SECONDS", "60")
+        ),
+        auth_mode=os.getenv("MCP_GATEWAY_AUTH_MODE"),
+        basic_client_id=os.getenv(
+            "MCP_GATEWAY_BASIC_CLIENT_ID"
+        ),
+        basic_secret=os.getenv(
+            "MCP_GATEWAY_BASIC_SECRET"
+        ),
+    )
+```
+
+---
+
+# 7. Configurar o MCP Gateway
+
+Entre no diretório:
+
+```bash
+cd apps/mcp_gateway
+```
+
+Crie `.env`:
+
+```bash
+cp .env.example .env
+```
+
+Adicione:
+
+```env
+# Entrada: Agent Backend -> MCP Gateway
+MCP_GATEWAY_AUTH_ENABLED=true
+MCP_GATEWAY_AUTH_MODE=basic
+MCP_GATEWAY_AUTH_BASIC_CLIENT_ID=agent-backend-test
+MCP_GATEWAY_AUTH_BASIC_SECRET_HASH=COLE_AQUI_HASH_BACKEND_MCP
+MCP_GATEWAY_AUTH_BASIC_REALM=mcp-gateway
+
+MCP_GATEWAY_AUTH_PUBLIC_PATHS=/health,/ready,/docs,/openapi.json,/redoc
+MCP_GATEWAY_AUTH_PUBLIC_PREFIXES=
+
+MCP_GATEWAY_CONFIG_PATH=config/mcp_gateway.yaml
+```
+
+## Desabilitar o mecanismo Bearer legado
+
+O MCP Gateway ainda possui um segundo mecanismo antigo, configurado dentro de:
+
+```text
+apps/mcp_gateway/config/mcp_gateway.yaml
+```
+
+Localize a seção:
+
+```yaml
+auth:
+  enabled: true
+```
+
+Altere para:
+
+```yaml
+auth:
+  enabled: false
+```
+
+Isso é necessário porque o novo middleware já faz a autenticação Basic. Caso o `auth_check()` legado continue habilitado, a requisição passará pelo Basic e depois será rejeitada por não possuir Bearer Token.
+
+---
+
+# 8. Subir os componentes
+
+Use quatro terminais.
+
+## Terminal 1 — MCP Servers
+
+O MCP Gateway precisa ter pelo menos um servidor MCP disponível para demonstrar uma chamada real.
+
+Na raiz do projeto:
+
+```bash
+source .venv/bin/activate
+```
+
+Suba o servidor telecom:
+
+```bash
+uvicorn mcp.servers.telecom_mcp_server.main:app \
+  --host 0.0.0.0 \
+  --port 8100 \
+  --reload
+```
+
+Em outro terminal, caso queira também o retail:
+
+```bash
+uvicorn mcp.servers.retail_mcp_server.main:app \
+  --host 0.0.0.0 \
+  --port 8200 \
+  --reload
+```
+
+Confira as URLs configuradas em:
+
+```text
+apps/mcp_gateway/config/mcp_gateway.yaml
+```
+
+Para execução local, devem apontar para:
+
+```yaml
+url: http://localhost:8100
+```
+
+e:
+
+```yaml
+url: http://localhost:8200
+```
+
+---
+
+## Terminal 2 — MCP Gateway
+
+```bash
+cd apps/mcp_gateway
+source ../../.venv/bin/activate
+```
+
+Suba usando `--env-file`. Isso é importante porque o middleware lê variáveis com `os.getenv()`:
+
+```bash
+uvicorn app.main:app \
+  --host 0.0.0.0 \
+  --port 8300 \
+  --reload \
+  --env-file .env
+```
+
+Teste a saúde pública:
+
+```bash
+curl http://localhost:8300/health

+```bash
+curl -i http://localhost:8300/v1/tools
+```
+
+Esperado:

+  }'
+```
+

+
+## Terminal 4 — Agent Gateway
+
+```bash
+cd apps/agent_gateway
+source ../../.venv/bin/activate
+```
+
+Suba:
+
+```bash
+uvicorn app.main:app \

+# 9. Validar o circuito completo
+
+Force o backend `contas` para evitar que o roteador selecione um backend não iniciado:
+
+```bash
+curl -X POST http://localhost:8010/gateway/message \
+  -u 'tia-test:TiaGateway-Test-2026!' \
+  -H 'Content-Type: application/json' \
+  -d '{

+    "tenant_id": "default",
+    "agent_id": "telecom_contas",
+    "session_id": "circuito-basic-001",
+    "payload": {
+      "text": "Quero consultar minha fatura",

+      "customer_id": "12345",
+      "message_id": "msg-circuito-001"
+    }
+  }'
+```
+
+O circuito esperado é:
+
+```text
+curl
+  │ Basic tia-test
+  ▼
+Agent Gateway :8010
+  │ Basic agent-gateway-test
+  ▼
+Agent Backend :8000

+
+# 10. Como comprovar cada autenticação
+
+Faça testes negativos em cada trecho.
+
+## Secret externo incorreto
+
+```bash
+curl -i \
+  -u 'tia-test:senha-errada' \
+  http://localhost:8010/backends
+```
+
+Resultado esperado:
+
+```text
+401 Unauthorized
+```
+
+## Secret do gateway para backend incorreto
+
+Altere temporariamente no `apps/agent_gateway/.env`:
+
+```env
+BACKEND_AUTH_SECRET=senha-errada
+```
+
+Reinicie o Agent Gateway e envie uma mensagem.
+
+O gateway deverá retornar erro de backend, normalmente:
+
+```text
+502 Bad Gateway
+```
+
+O erro interno será originado por um:
+
+```text
+401 Unauthorized
+```
+
+do Agent Backend.
+
+## Secret do backend para MCP incorreto
+
+Altere temporariamente:
+
+```env
+MCP_GATEWAY_BASIC_SECRET=senha-errada
+```
+
+Reinicie o backend e execute uma frase que acione uma ferramenta MCP.
+
+O backend deverá registrar falha na chamada ao MCP Gateway com:
+
+```text
+401 Unauthorized
+```
+
+---
+
+# 11. Verificação rápida de portas
+
+No Linux ou WSL:
+
+```bash
+ss -lntp | grep -E ':8000|:8010|:8100|:8200|:8300'
+```
+
+No Windows PowerShell:
+
+```powershell
+Get-NetTCPConnection -State Listen |
+  Where-Object LocalPort -in 8000,8010,8100,8200,8300 |
+  Sort-Object LocalPort
+```
+
+Você deverá ver:
+
+```text
+8000  Agent Backend
+8010  Agent Gateway
+8100  Telecom MCP Server
+8200  Retail MCP Server
+8300  MCP Gateway
+```
+
+## Observação importante
+
+O segredo original precisa existir no componente cliente:
+
+```text
+TIA ou curl:
+  TiaGateway-Test-2026!
+
+Agent Gateway:
+  GatewayBackend-Test-2026!
+
+Agent Backend:
+  BackendMcp-Test-2026!
+```
+
+Os componentes servidores armazenam apenas os hashes:
+
+```text
+Agent Gateway:
+  hash de TiaGateway-Test-2026!
+
+Agent Backend:
+  hash de GatewayBackend-Test-2026!
+
+MCP Gateway:
+  hash de BackendMcp-Test-2026!
+```
+
+Em produção, os segredos originais e hashes devem vir de Vault ou Kubernetes Secret, não de arquivos `.env`.

+# Disclaimer — template de autenticação
+
+Este conteúdo é um **template de referência técnica** criado para demonstrar como integrar mecanismos genéricos de autenticação ao Agent Framework OCI, ao Agent Gateway, ao MCP Gateway e a aplicações FastAPI independentes.
+
+O código, os arquivos YAML, as variáveis de ambiente, os providers, as políticas por rota e os exemplos de deployment **não constituem uma implementação final ou automaticamente adequada para produção**. Cada projeto deve lapidar e adaptar a solução conforme sua arquitetura, seus fluxos de confiança e suas exigências de segurança.
+
+Antes de usar em homologação ou produção, é responsabilidade da equipe do projeto avaliar e implementar, conforme aplicável:
+
+- integração com o provedor corporativo de identidade;
+- definição de autenticação e autorização por sistema, rota, método, tenant, role e scope;
+- armazenamento, distribuição e rotação de credenciais e chaves;
+- TLS ou mTLS e proteção das comunicações internas e externas;
+- bloqueio de acessos que contornem gateways ou proxies de confiança;
+- validação de issuer, audience, algoritmo, expiração e revogação de tokens;
+- proteção contra replay, brute force, credential stuffing e abuso de endpoints;
+- rate limiting, timeout, circuit breaker e controles de disponibilidade;
+- mascaramento de dados sensíveis em logs, traces e mensagens de erro;
+- auditoria, observabilidade, alertas e resposta a incidentes;
+- requisitos legais, regulatórios e políticas corporativas;
+- threat modeling, security review, testes de integração, testes de carga e testes de segurança.
+
+Os exemplos de Basic Authentication, API Key, Bearer estático, JWT, OAuth2 Introspection e Trusted Proxy devem ser entendidos como pontos de extensão. A seleção e a configuração finais dependem do cliente, da infraestrutura e do modelo de risco.
+
+A promoção para produção deve ocorrer somente após aprovação formal das equipes responsáveis por arquitetura, segurança, infraestrutura e operação.

+# Implementação técnica
+
+> [!IMPORTANT]
+> **Template de referência — requer adequação antes do uso produtivo.**
+> Esta implementação demonstra pontos de extensão, providers, middleware e exemplos de configuração para autenticação. Ela não deve ser considerada uma solução pronta para produção nem substitui o desenho de segurança do projeto. Antes da implantação, a equipe responsável deve revisar, testar e adaptar o código às políticas corporativas, ao modelo de identidade, à topologia de rede, à gestão e rotação de segredos, aos requisitos regulatórios, à observabilidade, à alta disponibilidade e ao processo de resposta a incidentes do ambiente do cliente. Recomenda-se executar security review, threat modeling, testes de integração e testes de segurança antes da homologação e da produção.
+## Biblioteca
+
+`libs/agent_framework/src/agent_framework/security` contém:
+
+- contratos e resultados de autenticação;
+- Basic, API Key, Bearer estático, JWT, OAuth2 Introspection e Trusted Proxy;
+- provider `none` para rotas públicas;
+- provider `deny` para default seguro;
+- middleware de provider único;
+- middleware de políticas por rota;
+- factory por ambiente ou mapping;
+- instalador reutilizável para qualquer app FastAPI.
+
+## Integrações
+
+- `apps/agent_gateway/app/main.py`: `AGENT_GATEWAY_AUTH_*`
+- `apps/mcp_gateway/app/main.py`: `MCP_GATEWAY_AUTH_*`
+- `Tuning-Performance/Authentication/agent_template_backend_authentication/app/main.py`: `AGENT_AUTH_*`
+
+Nenhuma integração é obrigatória. A instalação ocorre somente quando `*_AUTH_ENABLED=true`, quando um modo diferente de `none` é configurado ou quando existe `*_AUTH_POLICIES_FILE`.
+
+## Compatibilidade
+
+`AuthenticationMiddleware` e `create_authentication_provider()` foram mantidos para compatibilidade. O caminho recomendado para novos projetos é `install_authentication()`.

+Implementação de referência para autenticação transversal no Agent Framework OCI.
+
+Inclui:
+
+- providers genéricos em `libs/agent_framework/security`;
+- instalação opcional por `install_authentication()`;
+- políticas por rota, método, roles e scopes;
+- integração opcional em `apps/agent_gateway`;
+- integração opcional em `apps/mcp_gateway`;
+- backend independente autenticado em `agent_template_backend_authentication`;
+- exemplos YAML sem secrets embutidos;
+- manual completo no diretório `docs` do agente.
+
+A implementação não pressupõe o uso de gateways. Cada fronteira HTTP pode ativar autenticação com um prefixo de ambiente isolado.

+# Agent Template Backend Enterprise
+
+Este folder é uma cópia completa do `agent_template_backend`, sem cortes de
+arquitetura. Ele mantém workflow, router, output supervisor, guardrails,
+analytics, observer, MCP, memória, checkpoints e configurações.
+
+A diferença é que a lógica de negócio dos agentes de exemplo foi removida da
+execução e preservada comentada nos próprios arquivos:
+
+- `app/agents/billing_agent.py`
+- `app/agents/product_agent.py`
+- `app/agents/orders_agent.py`
+- `app/agents/support_agent.py`
+
+## O que o desenvolvedor deve alterar
+
+1. Escolher ou criar um agente em `app/agents/`.
+2. Implementar o método `run()`.
+3. Ajustar prompts e tools, se necessário.
+4. Emitir ICs de negócio relevantes para a jornada.
+5. Manter NOC/GRL nos pontos operacionais e de guardrails.
+
+## O que já está integrado
+
+- `AgentObserver`
+- `observer.emit_ic()`
+- `observer.emit_noc()`
+- `observer.emit_grl()`
+- `AnalyticsPublisher`
+- OCI Streaming
+- GCP Pub/Sub
+- OutputSupervisor
+- GuardrailPipeline com suporte a execução paralela/fail-fast no framework
+- MCP Tool Router
+- LangGraph
+- Memory
+- Checkpoint
+- Langfuse / OpenTelemetry
+
+## Exemplos adicionados
+
+Veja `app/examples/`:
+
+- `ic_examples.py`
+- `noc_examples.py`
+- `grl_examples.py`
+- `mcp_examples.py`
+- `observer_examples.py`
+
+## Convenção rápida
+
+- IC = evento de negócio / curadoria / informacional.
+- NOC = evento operacional / saúde técnica.
+- GRL = evento de guardrail / segurança / validação.

+# Atualização do Template Backend — Analytics, Observer, NOC/GRL e OutputSupervisor
+
+Esta versão do `agent_template_backend` foi atualizada para consumir as novidades transportadas para o `agent_framework`.
+
+## 1. Analytics e Pub/Sub
+
+O backend não chama mais diretamente apenas o publisher antigo de eventos. Agora ele cria um `AnalyticsPublisher`:
+
+```python
+from agent_framework.analytics.factory import create_analytics_publisher
+from agent_framework.observability.observer import AgentObserver
+
+analytics = create_analytics_publisher(settings)
+observer = AgentObserver(analytics=analytics)
+```
+
+Com isso, o mesmo backend pode publicar em:
+
+- OCI Streaming
+- GCP Pub/Sub
+- CompositePublisher, quando `ANALYTICS_PROVIDERS=oci_streaming,pubsub`
+- Noop, quando analytics estiver desligado
+
+## 2. Configuração mínima
+
+```env
+ENABLE_ANALYTICS=true
+ANALYTICS_PROVIDERS=pubsub
+GCP_PUBSUB_TOPIC_PATH=projects/<project-id>/topics/<topic-name>
+GOOGLE_APPLICATION_CREDENTIALS=/secrets/gcp-service-account.json
+```
+
+Para publicar simultaneamente em OCI Streaming e GCP Pub/Sub:
+
+```env
+ENABLE_ANALYTICS=true
+ANALYTICS_PROVIDERS=oci_streaming,pubsub
+ENABLE_OCI_STREAMING=true
+OCI_STREAM_ENDPOINT=<endpoint>
+OCI_STREAM_OCID=<stream-ocid>
+GCP_PUBSUB_TOPIC_PATH=projects/<project-id>/topics/<topic-name>
+```
+
+## 3. Observer corporativo
+
+O workflow recebeu emissão automática dos principais eventos corporativos:
+
+- `NOC.001`: início do workflow
+- `NOC.005`: exceção fatal no workflow
+- `NOC.006`: fim do workflow antes da resposta final
+- `IC.AGENT_COMPLETED`: evento informacional de conclusão
+- `GRL.001` a `GRL.009`: emitidos pelo `OutputSupervisor`
+
+## 4. OutputSupervisor
+
+Foi inserido um novo nó LangGraph:
+
+```text
+agent -> output_supervisor -> output_guardrails -> judge -> supervisor_review -> persist
+```
+
+O `OutputSupervisor` não substitui o supervisor de roteamento. Ele valida a saída candidata do agente usando o contrato corporativo:
+
+- `allow`
+- `sanitize`
+- `retry`
+- `block`
+- `handover`
+- `observe`
+
+Para compatibilidade com os guardrails já existentes, o template inclui o adapter `LegacyOutputGuardrailRail`, que converte decisões antigas `allowed=True/False` para `RailAction`.
+
+## 5. Campos adicionados ao AgentState
+
+```python
+supervisor_action: str
+supervisor_guidance: str
+supervisor_attempt: int
+supervisor_handover_reason: str
+output_supervisor_results: list[dict]
+output_guardrails_already_applied: bool
+```
+
+## 6. Arquivos alterados
+
+- `agent_template_backend/app/main.py`
+- `agent_template_backend/app/workflows/agent_graph.py`
+- `agent_template_backend/app/state.py`
+- `agent_template_backend/.env`
+- `agent_template_backend/requirements.txt`
+- `agent_framework/src/agent_framework/config/settings.py`
+
+## 7. Observação importante
+
+O `OutputSupervisor` roda os guardrails de saída por meio do adapter legado e marca `output_guardrails_already_applied=True`. Assim o nó `output_guardrails` permanece no grafo para compatibilidade, mas evita reexecutar a mesma validação quando o supervisor já aplicou os rails.

+# Como usar IC, NOC e GRL no Template Backend
+
+## IC — Item de Controle
+
+Use IC para registrar eventos de negócio relevantes.
+
+```python
+await observer.emit_ic(
+    "IC.FATURA_CONSULTADA",
+    {"session_id": session_id, "invoice_id": invoice_id},
+    component="billing_agent",
+)
+```
+
+## NOC — Evento operacional
+
+Use NOC para saúde técnica, latência, erros e checkpoints operacionais.
+
+```python
+await observer.emit_noc(
+    "003",
+    {"session_id": session_id, "resourceName": "ADB", "latencyMs": 120},
+    component="repository",
+)
+```
+
+## GRL — Evento de guardrail
+
+Normalmente o framework emite GRL automaticamente. Use manualmente apenas para
+rails customizados dentro do agente.
+
+```python
+await observer.emit_grl(
+    "OBSERVE",
+    {"session_id": session_id, "rail_code": "CUSTOM_POLICY"},
+    component="custom_rail",
+)
+```
+
+## Onde já existe no template
+
+- `app/workflows/agent_graph.py` emite IC/NOC no ciclo do workflow.
+- `app/agents/runtime.py` emite IC para MCP/tools.
+- `app/agents/*_agent.py` contém exemplos dentro do método `run()`.
+- `app/examples/` contém exemplos isolados.

+# Backends atualizados para ConversationSummaryMemory
+
+Esta versão dos backends foi compatibilizada com a versão do framework que adiciona `ConversationSummaryMemory`.
+
+## O que mudou
+
+- `app/main.py` agora inicializa `create_conversation_summary_memory(...)` junto com `create_memory(...)`.
+- `AgentWorkflow` recebe `summary_memory` e repassa para os agentes.
+- Os agentes não montam mais prompts manuais para o LLM; agora usam `build_messages()` do framework.
+- Antes da chamada ao LLM, os agentes executam `await self.prepare_memory_context(state)`.
+- Quando habilitado por `.env`, o prompt passa a receber:
+  - resumo acumulado da conversa;
+  - últimas mensagens completas;
+  - mensagem atual;
+  - BusinessContext;
+  - MCP results;
+  - RAG context e metadata.
+
+## Configuração
+
+```env
+ENABLE_CONVERSATION_SUMMARY_MEMORY=true
+MEMORY_CONTEXT_STRATEGY=summary
+MEMORY_HISTORY_LIMIT=80
+MEMORY_RECENT_MESSAGES_LIMIT=8
+MEMORY_SUMMARY_TRIGGER_MESSAGES=20
+MEMORY_MAX_SUMMARY_CHARS=6000
+MEMORY_SUMMARY_USE_LLM=true
+MEMORY_INJECT_RECENT_MESSAGES=true
+MEMORY_INJECT_SUMMARY=true
+```
+
+## Backends alterados
+
+- `backoffice_convertido_framework`
+- `agent_template_backend`
+- `agent_template_backend_day_zero`
+
+## Observação importante
+
+Estes backends esperam que o pacote `agent_framework` instalado/conectado seja a versão com os módulos:
+
+- `agent_framework.memory.summary_memory`
+- `agent_framework.memory.summary_store`
+- `AgentRuntimeMixin.prepare_memory_context()`
+- `AgentRuntimeMixin.build_messages()` com injeção de memória
+
+Use junto com o ZIP `agent_framework_conversation_summary_memory.zip`.

+# FRAMEWORK_CHANNEL_INPUT_MODE
+
+This backend setting controls what kind of channel input the Agent Framework backend accepts.
+
+It replaces the ambiguous use of `CHANNEL_GATEWAY_MODE` inside the backend.
+
+## Values
+
+```env
+FRAMEWORK_CHANNEL_INPUT_MODE=embedded
+```
+
+The backend may use internal channel adapters to interpret simple/native channel payloads. This is useful for demos, labs, local frontend, curl tests, and simple environments.
+
+```env
+FRAMEWORK_CHANNEL_INPUT_MODE=external
+```
+
+The backend accepts only a normalized `GatewayRequest` produced by an external Channel Gateway. It does not parse native WhatsApp, Voice, Teams, or other channel payloads.
+
+## Recommended enterprise setup
+
+In the external channel gateway service:
+
+```env
+CHANNEL_GATEWAY_RUNTIME_MODE=adapter
+```
+
+In this backend:
+
+```env
+FRAMEWORK_CHANNEL_INPUT_MODE=external
+```
+
+Flow:
+
+```text

+# Guardrails paralelos fail-fast e Observer IC
+
+## O que foi implementado
+
+### 1. ParallelRailExecutor
+
+Arquivo principal:
+
+```text
+agent_framework/src/agent_framework/guardrails/parallel_executor.py
+```
+
+Também foi criado um alias de compatibilidade:
+
+```text
+agent_framework/src/agent_framework/guardrails/executor.py
+```
+
+Esse alias evita erro quando algum código antigo importar:
+
+```python
+from agent_framework.guardrails.executor import ParallelRailExecutor
+```
+
+### 2. Execução paralela no GuardrailPipeline
+
+Arquivo alterado:
+
+```text
+agent_framework/src/agent_framework/guardrails/pipeline.py
+```
+
+O pipeline continua retornando o contrato antigo:
+
+```python
+(texto_final, list[RailDecision])
+```
+
+mas internamente pode executar rails em paralelo com fail-fast.
+
+### 3. Execução paralela no OutputSupervisor
+
+Arquivo alterado:
+
+```text
+agent_framework/src/agent_framework/guardrails/output_supervisor.py
+```
+
+O `OutputSupervisor` agora usa `ParallelRailExecutor` quando habilitado.
+
+### 4. Configuração
+
+Novas configurações:
+
+```env
+ENABLE_PARALLEL_GUARDRAILS=true
+GUARDRAILS_FAIL_FAST=true
+```
+
+Também foram adicionadas em:
+
+```text
+agent_framework/src/agent_framework/config/settings.py
+.env
+.env.example
+agent_template_backend/.env
+agent_template_backend_day_zero/.env
+```
+
+### 5. Observer IC
+
+O `AgentObserver` já tinha `emit_ic()`.
+
+Foi complementada a API global compatível com FIRST/TIM:
+
+```python
+from agent_framework.observer import ic, aic, noc, anoc, grl, agrl
+```
+
+Exemplos:
+
+```python
+ic("AGENT_COMPLETED", data={"session_id": "..."})
+await aic("MCP_TOOL_CALLED", data={"tool_name": "consultar_fatura"})
+```
+
+### 6. ICs automáticos no template backend
+
+O backend emite agora:
+
+```text
+IC.AGENT_STARTED
+IC.ROUTE_SELECTED
+IC.MCP_TOOL_CALLED
+IC.TOOL_CALLED
+IC.AGENT_COMPLETED
+```
+
+Além dos eventos já existentes:
+
+```text
+NOC.001
+NOC.005
+NOC.006
+GRL.001 ... GRL.009
+```
+
+## Validações executadas
+
+Foram executadas validações locais com `PYTHONPATH=agent_framework/src`:
+
+```bash
+python3 -m compileall -q agent_framework/src/agent_framework agent_template_backend/app agent_template_backend_day_zero/app
+```
+
+Smoke tests executados:
+
+```text
+1. Import de ParallelRailExecutor via agent_framework.guardrails
+2. Import de ParallelRailExecutor via agent_framework.guardrails.executor
+3. Execução fail-fast: FastBlock cancela SlowAllow
+4. GuardrailPipeline paralelo retorna RailDecision legado
+5. OutputSupervisor paralelo retorna RailAction.BLOCK
+6. API global observer.ic/noc/grl/aic/anoc/agrl
+```
+
+Observação: o import completo do `agent_template_backend.app.workflows.agent_graph` depende de `langgraph`, que não está instalado no sandbox de validação. O arquivo foi validado por `compileall`, e a dependência já consta em `agent_template_backend/requirements.txt`.

+# Implementação IC/NOC/GRL preservando lógica existente
+
+Esta versão mantém a lógica original dos agentes do `agent_template_backend` e adiciona observabilidade corporativa.
+
+## IC adicionados nos agentes
+
+Cada agente agora emite eventos de negócio sem alterar a resposta final:
+
+- `IC.BILLING_AGENT_STARTED` / `IC.BILLING_AGENT_COMPLETED`
+- `IC.ORDERS_AGENT_STARTED` / `IC.ORDERS_AGENT_COMPLETED`
+- `IC.PRODUCT_AGENT_STARTED` / `IC.PRODUCT_AGENT_COMPLETED`
+- `IC.SUPPORT_AGENT_STARTED` / `IC.SUPPORT_AGENT_COMPLETED`
+- `IC.<AGENT>_MCP_CONTEXT_COLLECTED` quando houver dados MCP
+- `IC.<AGENT>_RAG_CONTEXT_RETRIEVED` quando RAG estiver habilitado
+
+O mixin `AgentRuntimeMixin` também emite:
+
+- `IC.MCP_TOOL_CALLED` antes da chamada MCP
+- `IC.TOOL_CALLED` após a chamada MCP
+
+## NOC
+
+O workflow já emite eventos operacionais principais:
+
+- `NOC.001` no início da execução
+- `NOC.005` em exceção fatal
+- `NOC.006` na persistência/finalização
+
+## GRL
+
+O backend agora também exemplifica emissão GRL no workflow:
+
+- `GRL.001` início do pipeline de guardrails
+- `GRL.002` decisão allow
+- `GRL.004` decisão block
+- `GRL.009` decisão final agregada
+
+Quando `OutputSupervisor` está habilitado, ele continua sendo o principal mecanismo corporativo de supervisão de saída.
+
+## Garantia
+
+A lógica original dos agentes não foi substituída por stubs. As chamadas LLM, MCP, RAG, cache e os retornos originais foram preservados.

+# Langfuse single trace observer fix
+
+This backend now uses `TelemetryBackedAgentObserver` instead of publishing IC/NOC/GRL through `AgentObserver(analytics=...)`.
+
+Why: when analytics includes the Langfuse provider, observer events such as `IC.AGENT_COMPLETED` and `NOC.006` may create a second root trace with little detail. Emitting those events through `Telemetry.event(...)` keeps them inside the active request/workflow trace.

+# Manual geral de autenticação do Agent Framework OCI
+
+> [!IMPORTANT]
+> **Template de referência — requer adequação antes do uso produtivo.**
+> Esta implementação demonstra pontos de extensão, providers, middleware e exemplos de configuração para autenticação. Ela não deve ser considerada uma solução pronta para produção nem substitui o desenho de segurança do projeto. Antes da implantação, a equipe responsável deve revisar, testar e adaptar o código às políticas corporativas, ao modelo de identidade, à topologia de rede, à gestão e rotação de segredos, aos requisitos regulatórios, à observabilidade, à alta disponibilidade e ao processo de resposta a incidentes do ambiente do cliente. Recomenda-se executar security review, threat modeling, testes de integração e testes de segurança antes da homologação e da produção.
+## 1. Princípio arquitetural
+
+A autenticação é uma capacidade transversal, opcional e reutilizável. Ela não depende da presença do `agent_gateway` ou do `mcp_gateway` e pode ser instalada em qualquer aplicação FastAPI que exponha uma fronteira protegida.
+
+```text
+agent_framework.security
+  ├── backend independente de agente
+  ├── agent_gateway
+  ├── mcp_gateway
+  ├── channel_gateway
+  ├── MCP Server
+  └── aplicação customizada
+```
+
+O framework fornece providers, middleware, instalação por configuração e políticas por rota. Cada projeto ou deployment decide onde ativar e qual mecanismo usar.
+
+## 2. Onde autenticar
+
+| Arquitetura | Ponto principal de autenticação |
+|---|---|
+| TIA → Agente Contas diretamente | backend do Agente Contas |
+| TIA → Agent Gateway → Agente | Agent Gateway; backend deve ficar inacessível externamente ou usar autenticação interna |
+| Agente → MCP Gateway → MCP Servers | MCP Gateway, com autorização adicional por agente e ferramenta |
+| Agente → MCP Server diretamente | MCP Server |
+
+Autenticar no gateway só libera o backend de autenticação externa quando o acesso direto ao backend é bloqueado por rede, `ClusterIP`, NetworkPolicy, security group, service mesh ou mTLS.
+
+## 3. Instalação no código
+
+Use a mesma função em qualquer app FastAPI, mudando apenas o prefixo:
+
+```python
+from fastapi import FastAPI
+from agent_framework.security import install_authentication
+
+app = FastAPI()
+install_authentication(app, prefix="AGENT_AUTH")
+```
+
+Integrações fornecidas neste pacote:
+
+```python
+# Backend independente/template de autenticação
+install_authentication(app, prefix="AGENT_AUTH")
+
+# apps/agent_gateway
+install_authentication(app, prefix="AGENT_GATEWAY_AUTH")
+
+# apps/mcp_gateway
+install_authentication(app, prefix="MCP_GATEWAY_AUTH")
+```
+
+A autenticação permanece opcional. Sem ativação, o comportamento original da aplicação é preservado.
+
+## 4. Providers disponíveis
+
+| Modo | Uso típico |
+|---|---|
+| `none` | rota pública ou desenvolvimento local |
+| `deny` | rejeição explícita/default seguro em políticas |
+| `basic` | integração system-to-system controlada, como TIA → Contas |
+| `api_key` | integração simples entre serviços |
+| `bearer_static` | token estático com rotação |
+| `jwt` | access token JWT emitido por OAuth2/OIDC |
+| `oauth2_introspection` | token opaco validado no authorization server |
+| `trusted_proxy` | identidade validada por API Gateway, ingress ou service mesh |
+
+mTLS deve ser terminado no ingress, API Gateway ou service mesh. A identidade resultante pode ser encaminhada com `trusted_proxy`, desde que o acesso direto e os headers internos sejam protegidos.
+
+## 5. Configuração simples com um provider por aplicação
+
+### Agente independente com Basic
+
+```bash
+AGENT_AUTH_ENABLED=true
+AGENT_AUTH_MODE=basic
+AGENT_AUTH_BASIC_CLIENT_ID=tia-contas
+AGENT_AUTH_BASIC_SECRET_HASH=pbkdf2_sha256:310000:<salt>:<digest>
+AGENT_AUTH_BASIC_REALM=agent-contas
+AGENT_AUTH_PUBLIC_PATHS=/health
+```
+
+### Agent Gateway com JWT
+
+```bash
+AGENT_GATEWAY_AUTH_ENABLED=true
+AGENT_GATEWAY_AUTH_MODE=jwt
+AGENT_GATEWAY_AUTH_JWT_KEY=<public-key-pem>
+AGENT_GATEWAY_AUTH_JWT_ALGORITHMS=RS256
+AGENT_GATEWAY_AUTH_JWT_AUDIENCE=agent-gateway
+AGENT_GATEWAY_AUTH_JWT_ISSUER=https://identity.example.com/
+AGENT_GATEWAY_AUTH_PUBLIC_PATHS=/health,/ready,/live
+```
+
+### MCP Gateway com token de serviço
+
+```bash
+MCP_GATEWAY_AUTH_ENABLED=true
+MCP_GATEWAY_AUTH_MODE=bearer_static
+MCP_GATEWAY_AUTH_BEARER_TOKEN_HASH=sha256:<digest>
+MCP_GATEWAY_AUTH_BEARER_PRINCIPAL=agent-platform
+MCP_GATEWAY_AUTH_PUBLIC_PATHS=/health
+```
+
+## 6. Políticas por rota
+
+Use um arquivo YAML quando uma aplicação precisar de providers ou requisitos diferentes por endpoint:
+
+```bash
+AGENT_AUTH_ENABLED=true
+AGENT_AUTH_POLICIES_FILE=config/authentication.yaml
+```
+
+Para gateways, use respectivamente:
+
+```bash
+AGENT_GATEWAY_AUTH_POLICIES_FILE=config/authentication.yaml
+MCP_GATEWAY_AUTH_POLICIES_FILE=config/authentication.yaml
+```
+
+Exemplo:
+
+```yaml
+providers:
+  public:
+    mode: none
+
+  deny:
+    mode: deny
+
+  tia_basic:
+    mode: basic
+    client_id_env: TIA_AGENT_CLIENT_ID
+    secret_hash_env: TIA_AGENT_SECRET_HASH
+    realm: agent-contas
+
+  platform_jwt:
+    mode: jwt
+    key_env: PLATFORM_JWT_PUBLIC_KEY
+    algorithms: [RS256]
+    audience: agent-platform
+    issuer: https://identity.example.com/
+
+policies:
+  - name: health-public
+    provider: public
+    paths: [/health, /ready, /live]
+
+  - name: tia-messages
+    provider: tia_basic
+    paths: [/gateway/message, /gateway/message/sse, /gateway/events/*]
+
+  - name: administration
+    provider: platform_jwt
+    paths: [/debug/*, /admin/*]
+    required_roles: [platform-admin]
+    required_scopes: [agent.admin]
+
+default_provider: deny
+```
+
+As políticas são avaliadas na ordem declarada; a primeira correspondência vence. Os paths usam padrões glob, como `/gateway/events/*`. Quando `default_provider` é omitido, o comportamento é `deny`.
+
+Secrets nunca devem ser gravados no YAML. Use campos como `secret_hash_env`, `key_env` e `client_secret_env`.
+
+Arquivos de exemplo:
+
+- `Tuning-Performance/Authentication/authentication_policies.example.yaml`
+- `apps/agent_gateway/config/authentication.example.yaml`
+- `apps/mcp_gateway/config/authentication.example.yaml`
+- `agent_template_backend_authentication/config/authentication.example.yaml`
+
+## 7. Roles e scopes
+
+Após autenticar, o middleware extrai roles de `roles`, `role` ou `groups`, e scopes de `scope`, `scp` ou `scopes`. Requisitos ausentes retornam `403 Forbidden`.
+
+```yaml
+required_roles: [platform-admin]
+required_scopes: [agent.admin]
+```
+
+Basic, API Key e tokens estáticos identificam o consumidor, mas não produzem roles/scopes por padrão. Para autorização granular, use JWT/OAuth2, um provider customizado ou uma camada de autorização específica.
+
+No MCP Gateway, autenticação não substitui a autorização por `agent_id`, tenant, ferramenta e tipo de operação.
+
+## 8. Azure DevOps, Azure Key Vault e Kubernetes
+
+O pipeline recupera secrets do Azure Key Vault e os injeta no deployment. O framework não chama Azure DevOps nem Key Vault diretamente.
+
+```yaml
+env:
+  - name: AGENT_AUTH_ENABLED
+    value: "true"
+  - name: AGENT_AUTH_MODE
+    value: basic
+  - name: AGENT_AUTH_BASIC_CLIENT_ID
+    valueFrom:
+      secretKeyRef:
+        name: contas-auth
+        key: client-id
+  - name: AGENT_AUTH_BASIC_SECRET_HASH
+    valueFrom:
+      secretKeyRef:
+        name: contas-auth
+        key: secret-hash
+```
+
+No cenário TIA → Contas, o TIA mantém o secret original e o agente pode armazenar somente o hash de validação.
+
+## 9. Provider customizado
+
+Um provider específico implementa somente:
+
+```python
+class AuthenticationProvider(Protocol):
+    async def authenticate(self, request: Request) -> AuthenticationResult: ...
+```
+
+Nomes e regras particulares de TIA, GStreamer, TIM, Azure ou outro cliente devem ficar no projeto do cliente. A biblioteca deve permanecer genérica.
+
+## 10. Testes rápidos
+
+Sem credencial:
+
+```bash
+curl -i http://localhost:8000/gateway/message
+```
+
+Basic:
+
+```bash
+curl -i -u 'tia-contas:secret-original' \
+  -H 'Content-Type: application/json' \
+  -d '{"channel":"web","payload":{"text":"Olá","session_id":"auth-test","user_id":"tia"}}' \
+  http://localhost:8000/gateway/message
+```
+
+## 11. Requisitos mínimos
+
+- TLS obrigatório fora de localhost.
+- Nunca registrar `Authorization`, API keys, secrets ou tokens.
+- Restringir acesso direto aos backends quando a autenticação estiver centralizada no gateway.
+- Usar comparação em tempo constante para credenciais estáticas.
+- Usar PBKDF2 para secrets humanos e rotação periódica.
+- Proteger `/debug`, sessões, métricas e documentação.
+- Não confiar em headers de identidade vindos diretamente da internet.
+- Separar autenticação, autorização e confirmação transacional.
+- Aplicar rate limiting, limites de payload e auditoria no ingress/gateway.

+# Teste e diagnóstico de Long-Term Memory
+
+## O que foi corrigido
+
+1. A LTM agora é carregada explicitamente antes do roteamento.
+2. O estado recebe uma chave estável em `long_term_memory_subject_key`, baseada em `business_context.customer_key` e, como fallback, `user_id`.
+3. O resultado de carga e persistência aparece em `metadata.long_term_memory` da resposta.
+4. `/health` informa a configuração efetiva de LTM carregada pelo processo.
+5. Falhas de leitura e gravação geram eventos `long_term_memory.load.failed` e `long_term_memory.persist.failed`.
+
+## Teste
+
+Primeira sessão:
+
+```bash
+curl -s http://localhost:8000/gateway/message \
+  -H 'Content-Type: application/json' \
+  -d '{
+    "channel":"web",
+    "payload":{
+      "text":"Meu nome preferido é Cris e minha linguagem preferida é Python.",
+      "session_id":"ltm-session-001",
+      "user_id":"ltm-user-001",
+      "customer_id":"ltm-customer-001"
+    }
+  }'
+```
+
+Verifique na resposta:
+
+```json
+"long_term_memory": {
+  "subject_key": "ltm-customer-001",
+  "write_result": {
+    "saved": 2
+  }
+}
+```
+
+Nova sessão, mesma identidade:
+
+```bash
+curl -s http://localhost:8000/gateway/message \
+  -H 'Content-Type: application/json' \
+  -d '{
+    "channel":"web",
+    "payload":{
+      "text":"Qual é meu nome preferido e qual linguagem eu prefiro?",
+      "session_id":"ltm-session-002",
+      "user_id":"ltm-user-001",
+      "customer_id":"ltm-customer-001"
+    }
+  }'
+```
+
+Na segunda resposta, confira:
+
+- `metadata.long_term_memory.subject_key` igual à primeira chamada;
+- `metadata.long_term_memory.loaded` com registros;
+- `metadata.long_term_memory.context` preenchido;
+- ausência de `load_error`.
+
+## Diagnóstico rápido
+
+```bash
+curl -s http://localhost:8000/health
+```
+
+A seção `long_term_memory` deve mostrar:
+
+```json
+{
+  "enabled": true,
+  "provider": "sqlite",
+  "sqlite_path": "./data/agent_framework.db",
+  "table": "agentfw_long_term_memory",
+  "auto_extract": true,
+  "inject_context": true
+}
+```
+
+Execute o backend com o diretório do projeto como diretório de trabalho. Como o caminho SQLite é relativo, iniciar a aplicação em outro diretório pode criar ou consultar outro arquivo `./data/agent_framework.db`.
