Subject: [PATCH] docs: optimize and streamline documentation (59% reduction)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Major documentation refactoring to eliminate duplications and improve maintainability:

CLAUDE.md (562→230 lines, 59% reduction):
- Eliminated duplicate content with README.md
- Added smart references to detailed documentation
- Streamlined "Common Development Tasks" with golden rules
- Created comprehensive "Documentation Index" as single source of truth
- Focused on AI-friendly quick reference patterns

README.md (402→251 lines, 37% reduction):
- Simplified Quick Start to single command
- Condensed Tech Stack to one-line summary with CLAUDE.md reference
- Merged "Development Commands" + "Testing" into compact section
- Updated Production Deployment with modern workflow (Publish-And-Deploy.ps1, ROA2WEB-Console.ps1)
- Added Frontend Styling & CSS documentation references

Key improvements:
- Zero duplications across documentation files
- Clear separation: README.md = quick start, CLAUDE.md = development guide
- Smart cross-references between docs
- Updated deployment section with current scripts

 ### Key Architectural Decisions
-- **Shared Database Connection Pool**: Singleton `OraclePool` class in `shared/database/oracle_pool.py` is shared across all microservices. Uses `python-oracledb` with connection pooling.
-- **Centralized Authentication**: JWT-based auth in `shared/auth/` with middleware that auto-injects user data into `request.state`.
-- **SSH Tunnel Requirement**: All Oracle DB connections go through an SSH tunnel to the remote server (see Database Setup below).
-- **FastAPI Structure**: Routers in `backend/app/routers/`, schemas in `backend/app/schemas/`, no traditional models (Oracle stored procedures used instead).
-- **Telegram Bot Frontend**: Alternative command-based interface for Telegram. Uses standalone SQLite database for Telegram-specific data (auth codes, sessions) and communicates with backend via HTTP API.
+- **Shared Database Pool**: Singleton `OraclePool` in `shared/database/oracle_pool.py` (python-oracledb with connection pooling)
+- **Centralized Auth**: JWT-based auth in `shared/auth/` with middleware auto-injecting `request.state.user`
+- **SSH Tunnel**: Required for Oracle DB connections (development/Linux) - see Database Setup

 ## 🗄️ Database Setup
 
-**Schema**: `CONTAFIN_ORACLE` - Used for authentication and user management
-**Connection Method**: SSH tunnel required (Oracle DB is on remote network)
+**Schema**: `CONTAFIN_ORACLE` (authentication and user management)
+**Connection**: SSH tunnel required (Oracle on remote network)
 
-### SSH Tunnel Management
+### SSH Tunnel (Development/Linux)
 ```bash
-./ssh_tunnel.sh start     # Start tunnel (localhost:1526 -> remote:1521)
+./ssh_tunnel.sh start     # localhost:1526 → remote:1521
+./ssh_tunnel.sh status    # Check tunnel
 ./ssh_tunnel.sh stop      # Stop tunnel
-./ssh_tunnel.sh status    # Check tunnel status
-./ssh_tunnel.sh restart   # Restart tunnel
 ```
 
-**SSH Configuration**:
-- Remote Server: `83.103.197.79:22122`
-- User: `roa2web`
-- SSH Key: `ssh-tunnel/secrets/roa_oracle_server`
-- Local Port: `1526`
-- Remote Oracle: `10.0.20.36:1521`
-
 **IMPORTANT**: Always ensure SSH tunnel is running before starting backend services.
 
-### Environment Variables

 ## 🔑 Authentication Flow
 
-1. **Login**: `POST /api/auth/login` calls Oracle stored procedure `pack_drepturi.verificautilizator(username, password)`
-2. **Token Generation**: JWT token includes `username`, `user_id`, `companies[]`, `permissions[]`, `exp`, `iat`, `type`
-3. **Middleware**: `AuthenticationMiddleware` in `shared/auth/middleware.py` auto-validates tokens and injects user into `request.state.user`
-4. **Protected Routes**: All routes except `excluded_paths` require valid JWT token
+1. **Login**: `POST /api/auth/login` → calls `pack_drepturi.verificautilizator(username, password)`
+2. **Token**: JWT includes `username`, `user_id`, `companies[]`, `permissions[]`, `exp`, `iat`, `type`
+3. **Middleware**: `AuthenticationMiddleware` in `shared/auth/middleware.py` validates tokens, injects user
+4. **Protected Routes**: All routes except `excluded_paths` require valid JWT
 
 **Key Files**:
-- `shared/auth/middleware.py` - FastAPI middleware with rate limiting
+- `shared/auth/middleware.py` - FastAPI middleware with rate limiting (5 req/5 min)
 - `shared/auth/jwt_handler.py` - Token creation/validation
 - `reports-app/backend/app/main.py` - Auth router inline definition

-### Development Commands
-
-```bash
-cd reports-app/telegram-bot/
-
-# Create virtual environment
-python3 -m venv venv
-source venv/bin/activate
-
-# Install dependencies
-pip install -r requirements.txt
-
-# Configure environment
-cp .env.example .env
-# Edit .env with TELEGRAM_BOT_TOKEN
-
-# Run bot
-python -m app.main
-
-# Health check
-curl http://localhost:8002/internal/health
-```
-
-### Authentication Flow (Telegram)
-
-1. User logs into ROA2WEB web app
-2. User requests Telegram linking → Backend generates 8-char code
-3. Backend saves code to telegram-bot via `POST /internal/save-code` (port 8002)
-4. User sends code to Telegram bot: `/start ABC123XY`
-5. Bot verifies code, creates user in SQLite, receives JWT token
-6. User can now use commands to query data
-
-### Bot Commands
-
-- `/start [code]` - Welcome message or link account with code
-- `/help` - Usage guide and available commands
-- `/companies` - View accessible companies
-- `/selectcompany [name]` - Select or search for active company
-- `/dashboard` - View financial dashboard for active company
-- `/sold` - View balance (alias for `/dashboard`)
-- `/facturi [filter]` - View invoices (optional filters: neplatite, platite)
-- `/trezorerie` - View treasury/payment data
-- `/clear` - Clear active company selection
-- `/unlink` - Unlink Telegram from Oracle account
-
-### Database (SQLite)
-
-Standalone database in `data/telegram_bot.db`:
-- **telegram_users**: Telegram-Oracle account linking
-- **telegram_auth_codes**: 8-char codes (15 min expiry)
-- **telegram_sessions**: Active company selection
-
-Automatic cleanup runs hourly to remove expired data.
-
-### Testing
-
-```bash
-# Unit and integration tests
-pytest tests/ -v
-
-# Coverage report
-pytest tests/ --cov=app --cov-report=html

-## 🐳 Docker & Production
-
-### Docker Compose (Legacy Flask App)
-The root `docker-compose.yaml` is for the old Flask application - NOT for the current FastAPI/Vue.js app.
-
-### Production Deployment Options
-
-ROA2WEB supports two production deployment architectures:
-
-#### 🐧 Linux Production (Docker)
-
-```bash
-# Setup production environment
-./setup_production.sh
-
-# Deployment scripts
-./scripts/deploy.sh           # Deploy application
-./scripts/backup.sh           # Backup data
-./scripts/rollback.sh         # Rollback deployment
-./scripts/health-check.sh     # Health monitoring
-```
-
-See `DEPLOYMENT_GUIDE.md` for full Linux/Docker deployment instructions.
-
-#### 🪟 Windows Server Production (IIS)
-
-Windows Server deployment uses IIS and Windows Services without Docker:
-
-**Build deployment package (on WSL/Linux development machine):**
-```powershell
-cd deployment/windows/scripts
-
-# Build complete package (Frontend + Backend + Telegram Bot)
-.\Build-ROA2WEB.ps1
-
-# Or build specific components
-.\Build-ROA2WEB.ps1 -Component Frontend      # Frontend + Backend only
-.\Build-ROA2WEB.ps1 -Component TelegramBot   # Telegram Bot only
-
-# Output: ./deploy-package/
-# Transfer this to Windows Server
-```
-
-**Deploy on Windows Server (PowerShell as Administrator):**
-```powershell
-# Initial installation
-cd C:\path\to\deploy-package\scripts
-
-# Install main application
-.\Install-ROA2WEB.ps1
-
-# Install Telegram Bot
-.\Install-TelegramBot.ps1
-
-# Configure applications
-notepad C:\inetpub\wwwroot\roa2web\backend\.env
-notepad C:\inetpub\wwwroot\roa2web\telegram-bot\.env
-
-# Deploy/update application files
-.\Deploy-ROA2WEB.ps1
-.\Deploy-TelegramBot.ps1
-
-# Service Management (Unified)
-.\Manage-ROA2WEB.ps1 -Action Start              # Start all services
-.\Manage-ROA2WEB.ps1 -Action Stop               # Stop all services
-.\Manage-ROA2WEB.ps1 -Action Restart            # Restart all services
-.\Manage-ROA2WEB.ps1 -Action Status             # Check status
-
-# Manage specific components
-.\Manage-ROA2WEB.ps1 -Action Start -Component Backend
-.\Manage-ROA2WEB.ps1 -Action Restart -Component TelegramBot
-```
-
-**Windows Deployment Architecture:**
-- **IIS Web Server**: Serves frontend static files (port 80/443)
-- **Windows Service**: FastAPI backend via NSSM (port 8000)
-- **Windows Service**: Telegram Bot via NSSM (internal API port 8002)
-- **Direct Oracle Connection**: No SSH tunnel required
-- **URL Rewrite Module**: Reverse proxy for `/api/*` routes
-
-**Telegram Bot Integration:**
-- Backend must have `TELEGRAM_BOT_INTERNAL_API=http://localhost:8002` in `.env`
-- Telegram Bot service must be running before generating linking codes
-- Troubleshooting: See `deployment/windows/docs/TELEGRAM_BOT_TROUBLESHOOTING.md`

-2. Import using `sys.path.append()` pattern (see `backend/app/main.py:21`)
-3. Test in `shared/tests/`
-
-### Working with Oracle Stored Procedures
+**Example**:
 ```python
 async with oracle_pool.get_connection() as connection:
     with connection.cursor() as cursor:
         cursor.execute("""
             SELECT pack_name.procedure_name(:param1, :param2)
             FROM DUAL

-        })
+        """, {'param1': value1, 'param2': value2})
         result = cursor.fetchone()
 ```
 
+### Adding a New Frontend Page/Component
+**IMPORTANT**: Follow the established CSS architecture and design system.
+
+**Before writing ANY CSS**: Read **`docs/ONBOARDING_CSS.md`** (5-minute quick start) → See "Documentation Index" below for complete guide list.
+
+**Golden Rules**:
+- ✅ Use global patterns first (`.roa-card`, `.roa-metric`, `.roa-badge-*`) - check `CSS_PATTERNS.md`
+- ✅ Use design tokens (`var(--color-primary)`) not hardcoded values (`#2563eb`)
+- ❌ Never use `:deep()` in components (use `src/assets/css/vendor/` for PrimeVue overrides)
+- ❌ Never duplicate CSS (write once, use everywhere)
+
+### Adding a New Telegram Bot Command
+**IMPORTANT**: Follow established command patterns and formatting.
+
+**Before coding**: Read **`reports-app/telegram-bot/TELEGRAM_COMMANDS.md`** for command patterns → See "Documentation Index" for complete guides.
+
+**Standard Pattern** (add handler in `app/bot/handlers.py`):
+```python
+async def your_command(update: Update, context: ContextTypes.DEFAULT_TYPE) -> None:
+    telegram_id = update.effective_user.id
+
+    # 1. Check authentication (use helpers.py)
+    user = await get_user_by_telegram_id(telegram_id)
+    if not user:
+        await update.message.reply_text("⚠️ Account not linked. Use /start with code.")
+        return
+
+    # 2. Check active company (use session.py)
+    active_company = await get_active_company(telegram_id)
+    if not active_company:
+        await update.message.reply_text("⚠️ Select company first: /selectcompany")
+        return
+
+    # 3. Call backend API (use api/client.py)
+    # 4. Format response (use formatters.py)
+    # 5. Add tests + update MANUAL_TESTING_CHECKLIST.md
+```
+
+### Adding Shared Functionality
+1. Place in `shared/{database|auth|utils}/`
+2. Import using `sys.path.append()` pattern (see `backend/app/main.py:21`)
+3. Add tests in `shared/tests/`
+
 ### Frontend API Integration
 ```javascript
-// Store pattern (src/stores/authStore.js)
+// Store pattern (src/stores/yourStore.js)
 import axios from 'axios';
 
 const api = axios.create({
   baseURL: 'http://localhost:8001/api',
