# Arcádia Suite - Office Estratégico Empresarial ## Overview Arcádia Suite is the **Strategic Office for the Modern Enterprise**, a platform designed to centralize productivity, intelligence, decision-making, and governance by orchestrating ERPs, people, and data. Its core principle is the absolute separation between decision and execution. The project envisions a future where Arcádia thinks, governs, and guides, while ERPs execute, record, and obey, aiming to revolutionize business automation through AI and intelligent agents. ## User Preferences - Preferred communication style: Simple, everyday language (Portuguese/Brazilian) - UI Style: Modern, WhatsApp Web-like interfaces - Focus: Business automation and AI-powered features ## System Architecture The Arcádia Suite employs a 4-layer hybrid architecture: ``` ┌─────────────────────────────────────────────────────────────────┐ │ PRESENTATION LAYER │ │ React 18 + TypeScript + Tailwind + shadcn/ui │ │ Browser-like interface with tabs and omnibox │ └─────────────────────────────────────────────────────────────────┘ ▼ ┌─────────────────────────────────────────────────────────────────┐ │ ORCHESTRATION LAYER │ │ Express.js + Socket.IO + Manus Agent │ │ Port 5000 (API + WebSocket) │ └─────────────────────────────────────────────────────────────────┘ ▼ ┌─────────────────────────────────────────────────────────────────┐ │ INTELLIGENCE LAYER │ │ FastAPI (Port 8001) + OpenAI API │ │ Scientist, Embeddings, RPA, Workflows │ │ FastAPI Fisco (Port 8002) - NF-e/NFC-e via nfelib │ └─────────────────────────────────────────────────────────────────┘ ▼ ┌─────────────────────────────────────────────────────────────────┐ │ DATA LAYER │ │ PostgreSQL + Knowledge Graph + ChromaDB │ │ Drizzle ORM + Session Store │ └─────────────────────────────────────────────────────────────────┘ ``` **Key Architectural Components & Features:** * **Arcádia Suite's 6-Layer Architecture:** Apps (Core, Business, Segment), Structural Modules (Financial, Accounting, Fiscal, HR), Operational Execution (Retail, Services, ERPs), Intelligence (Manus, Knowledge Graph, Automations), Platform (Central API, Hub API, MCP/A2A, IDE, Data Science), and Consulting (Process Compass, Production, Support). * **Unified Communication Center:** Integrates a WhatsApp Attendance System (multi-session, real-time sync, ticket management, AI auto-replies) and an Internal Chat System, feeding all communications into the Knowledge Graph. * **Learning System & Knowledge Graph:** The system learns from all interactions, storing Q&A and patterns. A semantic Knowledge Graph connects all business information via nodes and edges for insights. * **Manus Autonomous Agent (Cérebro Central):** Central AI brain (GPT-4o) powering all intelligence via ManusIntelligence singleton. All 6 Dev Center agents (Architect, Generator, Validator, Executor, Researcher, Evolution) route their AI thinking through ManusIntelligence, which provides context enrichment via ToolManager (code search, file reading). Executes multi-step tasks using a thought-action-observation loop with 56+ tools (web search, knowledge/ERP query, file I/O, shell commands, semantic search). Visible in Casa de Máquinas as "Motor IA" with health endpoint at `/api/manus/health` showing model, metrics (calls, tokens, errors), capabilities, and uptime. * **Scientist Module:** An AI auto-programming component for data analysis, code generation (Python/SQL) in a sandbox, and solution storage. * **Arcádia Fisco (Fiscal Engine):** Centralized compliance motor for Brazilian tax regulations (NCMs, CFOPs, CESTs, tax groups, digital certificates), integrating with SEFAZ webservices for NF-e/NFC-e issuance. * **Arcádia SOE (Sistema Operacional Empresarial):** The central business operating system (kernel) accessible via `/soe`. Contains all canonical business domains (People, Products, Sales, Purchases, Inventory, Financial, Fiscal, CRM, Projects, Quality, Governance). Apps (Retail, Engineering, Food Service, etc.) extend SOE with segment-specific experiences. Motors (Plus, ERPNext, Fisco, BI) are execution engines selected via server-side adapter pattern. API at `/api/soe/*` (backward-compatible alias from `/api/erp/*`). Context: `SoeMotorContext` replaces `ErpProfileContext`. Legacy file `ERP.tsx` preserved for reference. * **Arcádia Plus (ERP Laravel):** A standalone Laravel/PHP ERP, accessible via `/plus`, with extensive features including NF-e/NFC-e/CT-e/MDF-e, POS, digital menu, service orders, financial management, stock traceability, CRM, and integrations with e-commerce platforms. Uses an isolated PostgreSQL schema. * **Business Intelligence (Arcádia Insights):** Provides data visualization and analysis, powered by the BI Engine (FastAPI, port 8004) with SQL query execution, chart-data generation, micro-BI API, caching layer, and Pandas analysis. * **Automation Engine:** FastAPI service (port 8005) providing cron scheduler, event bus, and workflow executor for the Automations module. * **Communication Engine (Motor de Comunicação):** Node/TypeScript service (port 8006) unifying XOS CRM, Arcádia CRM, WhatsApp, and Email into a single managed engine. Provides unified API for contacts, threads, messages, channels, queues, quick messages, stats, and agent context (360° view). Emits events to `comm_events` table consumed by Knowledge Graph and AI agents. Proxy at `/api/comm/*`. Canonical tables: `comm_contacts`, `comm_threads`, `comm_messages`, `comm_channels`, `comm_queues`, `comm_quick_messages`, `comm_events`. Backward-compatible via reference fields (`xos_contact_id`, `crm_client_id`, etc.). * **Casa de Máquinas (Engine Room):** Unified control panel at `/engine-room` showing real-time status of all engines (Manus IA, Plus 8080, Contábil 8003, Fiscal 8002, BI 8004, Automation 8005, Communication 8006) and XOS agents. Manus IA has a dedicated tab with metrics (model, calls, tokens, errors, uptime, capabilities). API at `/api/engine-room/*`. * **IDE:** Integrated development environment with Monaco Editor and Xterm.js. * **Module Activation System:** Per-tenant module management via `tenants.features` JSONB column (TenantFeatures type). API at `GET/PUT /api/soe/tenant/modules`. Admin → Módulos tab provides toggle switches for each module. Backend gating middleware (`requireModule`) blocks sync endpoints when modules are disabled (returns 403 with actionable message). SOE Sync Dashboard at `/soe` tab "Sincronização" shows motor status, enabled/disabled state, and manual sync buttons. Frontend hook `useTenantFeatures()` provides feature checks. Feature keys: ide, whatsapp, crm, erp, bi, manus, retail, plus, fisco, cockpit, compass, production, support, xosCrm, centralApis, comunidades, biblioteca. * **Multi-Tenant Architecture:** Supports a hierarchical structure for Master, Partners, and Clients. * **Agentic Interoperability Protocols:** Implements MCP (Model Context Protocol) for tool exposure (`/api/mcp/v1/`), A2A (Agent to Agent Protocol) for bidirectional communication (`/api/a2a/v1/`), and planned AP2 (Agent Payment Protocol) and UCP (Unified Commerce Protocol). Authentication uses `X-API-Key`. * **Autonomous Development:** Integrated with GitHub for automatic commits, branch creation, pull requests, and repository analysis using a `ToolManager` system. * **XOS Governance Layer:** Policy evaluation engine with fail-closed security, immutable audit trail, tool registry (auto-synced from ToolManager), skill registry with usage tracking, and contract registry. Integrated into BaseBlackboardAgent and ToolManager for automatic policy checks. API at `/api/governance/*`. 5 security policies: critical file protection, read permissions, destructive command blocking, human approval for production deploys, automatic staging with validation score threshold. Phase 3 adds PostgreSQL Job Queue (xos_job_queue table with priority, retry, dead-letter), Agent Metrics (xos_agent_metrics), 6th Researcher agent, and a visual Governance Dashboard at `/xos/governance` with real-time stats, audit trail, policies, tools, skills, jobs, and agent monitoring. Phase 4 adds Autonomous Pipeline Orchestrator (PipelineOrchestrator.ts) that chains all 6 agents: Portuguese prompt → Architect (design) → Generator (codegen) → Validator (typecheck) → Executor (staging) → Evolution (learn). Staging review system (xos_staging_changes + xos_dev_pipelines tables) with explicit user approval before applying code. SSE streaming for real-time progress. Pipeline UI integrated as "Pipeline" tab within Dev Center (`/dev-center`) with enhanced prompt input (image paste, file attachment, plan section), live timeline, staged code review/approve/reject. `/xos/pipeline` redirects to Dev Center. API at `/api/xos/pipeline`. * **Modular Dev Center Architecture:** The XOS Pipeline agents can autonomously create complete modules (database schemas, API routes, and UI pages) using a modular system. Module schemas go to `shared/schemas/{moduleName}.ts` and are auto-registered in the main schema via `shared/schemas/index.ts`. Module routes go to `server/modules/{moduleName}.ts` and are auto-loaded at startup via `server/modules/loader.ts`, mounted at `/api/modules/{moduleName}`. After pipeline approval, the migrator (`server/modules/migrator.ts`) auto-registers schemas and runs `drizzle-kit push`. Core files (`shared/schema.ts`, `server/routes.ts`, `db/index.ts`, `shared/schemas/index.ts`, `shared/schemas/loader.ts`, `server/modules/loader.ts`) remain protected. Agent prompts (Architect, Generator) include instructions for the modular pattern. API at `/api/xos/pipeline/modules/status` shows registered schemas and loaded routes. ## External Dependencies * **OpenAI API:** For AI capabilities via ManusIntelligence (GPT-4o for Dev Center agents) and auto-replies (gpt-4o-mini for WhatsApp). * **Baileys Library:** For WhatsApp integration and multi-session management. * **nfelib (Python):** For Brazilian fiscal document (NF-e/NFC-e) issuance, validation, and SEFAZ communication. * **PostgreSQL:** Primary database, managed with Drizzle ORM. * **ChromaDB:** For vector embeddings, supporting the Knowledge Graph and AI components. * **Socket.IO:** For real-time communication (WhatsApp sync, internal chat). * **Monaco Editor:** For code editing within the IDE. * **Xterm.js:** For terminal emulation within the IDE. * **ERPNext API:** For integration with ERPNext operations (customers, products, sales orders, financial data).
