+# Summary: 03-02 — Node.js MiroFlow Bridge
+
+## What was built
+
+Bridge Node.js → Python para o MiroFlow: proxy TypeScript com timeout 300s, rotas Express autenticadas e registro imutável de execuções no KG via auditHash SHA-256.
+
+## Files created/modified
+
+### Created
+- `server/miroflow/engine-proxy.ts` — proxy para :8006, MIROFLOW_TIMEOUT=300_000ms, registerExecutionInKG com SHA-256
+- `server/miroflow/routes.ts` — re-export de registerMiroFlowRoutes
+
+### Modified
+- `server/routes.ts` — import + chamada registerMiroFlowRoutes(app) após registerBiEngineRoutes
+
+## Key decisions
+
+- Timeout de 300_000ms (5 min) para POST /analyze — adequado para deepseek-r1:14b
+- Health check usa timeout curto (5_000ms)
+- KG failure não bloqueia resposta ao cliente (try/catch com console.error)
+- auditHash cobre: execution_id + agent + model + input + output
+
+## TypeScript compilation
+
+Erros nos novos arquivos: **0**
+(Erros pré-existentes em App.tsx e server/modules/miroflow/ não relacionados)
+
+## Commits
