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.

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: Executes multi-step tasks using a thought-action-observation loop with various tools (web search, knowledge/ERP query, calculations, messaging, reporting, scheduling).
• 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 ERP (Gestão Empresarial): A complete ERP module integrating ERPNext with Arcádia's intelligence, accessible via /erp. Includes dashboards, unified people module, inventory, sales, purchases, financial management, AI-driven reports, and integration with Arcádia Fisco and Manus AI.
• 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 (Plus 8080, Contábil 8003, Fiscal 8002, BI 8004, Automation 8005, Communication 8006) and XOS agents. API at /api/engine-room/*.
• IDE: Integrated development environment with Monaco Editor and Xterm.js.
• 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 at /xos/pipeline with prompt submission, live timeline, and staged code review/approve/reject. API at /api/xos/pipeline.
