-# Fasto Project Documentation
-
-## Overview
-Fasto is a commercial team management system built with React (Vite) on the frontend and Node.js (Express) on the backend. It uses a MySQL database. It features a complete multi-tenant architecture designed to securely host multiple client organizations within a single deployment.
-
-## 🚀 Recent Major Changes (March 2026)
-We have transitioned from a mock-based prototype to a **secure, multi-tenant production architecture**:
-
-- **Multi-Tenancy & Data Isolation:** All backend routes (Users, Teams, Attendances) now strictly enforce `tenant_id` checks. It is technically impossible for one organization to query data from another.
-- **Advanced 2-Token Authentication (Rolling Sessions):**
-  - Replaced the vulnerable 1-year static JWT with a highly secure dual-token system.
-  - Generates a short-lived `AccessToken` (15 min) and a stateful `RefreshToken` (30 days) stored in the DB (`refresh_tokens` table).
-  - Built an Axios-like `apiFetch` interceptor on the frontend that automatically catches 401 Unauthorized errors, fetches a new Access Token in the background, extends the Refresh Token by another 30 days (Sliding Expiration), and retries the original request without logging the user out.
-  - Full remote revocation capability (Logout drops the token from the DB immediately).
-- **God Mode (Tenant Impersonation):** Super Admins can securely impersonate Tenant Admins via a specialized, temporary JWT (`/api/impersonate/:tenantId`). This allows seamless cross-domain support without storing passwords.
-- **Role-Based Access Control (RBAC) Simplification:**
-  - Removed the redundant 'owner' role. The system now strictly relies on 4 tiers:
-  - **Super Admin:** Global management of all tenants and API keys (via the hidden `system` tenant).
-  - **Admin:** Full control over members, teams, funnels, and origins within their specific organization.
-  - **Manager:** Mid-level control. Can edit basic info of users in their specific team, but cannot change user roles or re-assign users to different teams (only Admins can).
-  - **Agent:** Restricted access. Can only view their own performance metrics and historical attendances.
-- **Dynamic Funnel & Origin Managers:** 
-  - Funnel stages and Lead Origins are no longer hardcoded ENUMs. Each tenant can create multiple dynamic funnel/origin groups via relational tables (`funnels`, `funnel_stages`, `origin_groups`, `origin_items`).
-  - Admins can customize the exact Tailwind color class (e.g., "bg-green-100") for each stage and origin via visual UI pickers.
-  - Admins assign specific Teams to specific Funnels/Origin Groups.
-  - The Dashboard pie charts and data tables strictly filter and color-code data based on the active team's configuration. Deleted data falls back to an "Outros" category to prevent chart breakage.
-- **n8n / External API Webhooks (Completed):** 
-  - Super Admins can generate persistent `api_keys` for specific tenants.
-  - `GET /api/integration/users`, `/funnels`, and `/origins` allow the n8n AI to dynamically map the tenant's actual agents and workflow stages before processing a chat.
-  - `POST /api/integration/attendances` accepts the AI's final JSON payload (including the `full_summary` text) and injects it directly into the dashboard.
-- **Real-Time Notification System:** 
-  - Built a persistent notification tray (`/api/notifications`) with real-time polling (10s intervals) and a hidden HTML5 `<audio>` player for cross-browser sound playback (custom `.mp3` loaded via Vite).
-  - Automated Triggers: Super Admins are notified of new organizations; Admins/Super Admins are notified of new user setups; Agents are notified of team assignment changes; Managers get "Venda Fechada" alerts when n8n posts a converted lead.
-- **Enhanced UI/UX:** 
-  - Premium "Onyx & Gold" True Black dark mode (Zinc scale).
-  - Fully collapsible interactive sidebar with memory (`localStorage`).
-  - All Date/Time displays localized to strict Brazilian formatting (`pt-BR`, 24h, `DD/MM/YY`).
-
-## 📌 Roadmap / To-Do
-- [ ] **Advanced AI Notification Triggers:** Implement backend logic to automatically notify Managers when an attendance payload from n8n receives a critically low quality score (`score < 50`), or breaches a specific Response Time SLA (e.g., `first_response_time_min > 60`).
-- [ ] **Data Export/Reporting:** Allow Admins to export attendance and KPI data to CSV/Excel.
-- [ ] **Billing/Subscription Management:** Integrate a payment gateway (e.g., Stripe/Asaas) to manage tenant trial periods and active statuses dynamically.
-
-## 🛠 Architecture
-- **Frontend**: React 19, TypeScript, Vite, TailwindCSS (CDN), Recharts, Lucide React.
-- **Backend**: Node.js, Express, MySQL2 (Pool-based), Nodemailer.
-- **Database**: MySQL 8.0 (Schema: `fasto_db` or `agenciac_comia` depending on `.env`).
-- **Deployment**: Docker Compose for local development; Gitea Actions for CI/CD pushing to a Gitea Registry and deploying via Portainer webhook.
-
-## 📋 Prerequisites
-- Docker & Docker Compose
-- Node.js (for local development outside Docker)
-
-## ⚙️ Setup & Running
-
-### 1. Environment Variables
-Copy `.env.example` to `.env` and adjust values:
-```bash
-cp .env.example .env
-```
-*Note:* The backend automatically strips literal quotes from Docker `.env` string values (like `SMTP_PASS`) to prevent authentication crashes.
-
-### 2. Database
-The project expects a MySQL database. The Node.js backend automatically runs non-destructive schema migrations on startup (adding tables like `refresh_tokens`, `api_keys`, `origin_groups`, etc.).
-
-### 3. Running Locally (Docker Compose)
-To start the application and database locally:
-```bash
-docker-compose -f docker-compose.local.yml up -d --build
-```
-- **App**: http://localhost:3001
-- **Database**: Port 3306
-
-### 4. Gitea Runner
-The `docker-compose.yml` includes a service for a Gitea Runner (`fasto-runner`).
-- Persistent data is in `./fasto_runner/data`.
-
-## 🔄 CI/CD Pipeline
-The project uses Gitea Actions defined in `.gitea/workflows/build-deploy.yaml`.
-- **Triggers**: Push to `main` or `master`.
-- **Steps**:
-    1. Checkout code.
-    2. Build Docker image.
-    3. Push to `gitea.blyzer.com.br`.
-    4. Trigger Portainer webhook.
-
-## 💻 Development
-The Dockerfile uses a unified root structure. Both the frontend build and the backend Node.js server are hosted from the same container image.
