# COMPLETE EXECUTION GUIDE
## K-ArtSell Aegis v16.0 - Full Service Deployment to Live

**Date:** 2026-08-04 16:20 KST  
**Status:** ✅ **READY FOR COMPLETE EXECUTION**  
**Authority:** AGENTS.md v16.0 - Optimal Strategic Method  
**Mode:** LIVE DEPLOYMENT - ALL PHASES

---

## 🎯 COMPLETE EXECUTION STRATEGY

### Current State
```
✅ Phase 1:      RUNNING (Job 893, autonomous 50-90 days)
✅ Frontend:     Code & Config Ready
✅ Backend:      Code Ready for Deployment
✅ Database:     Connected & Migrated
✅ Documents:    Complete
```

### What Needs to Happen NOW
```
1. Terminal 3: Execute DEPLOY_PRODUCTION_NOW.ps1
2. Frontend: Build & Deploy
3. Nginx: Configure & Start
4. Verification: Full Integration Test
5. Result: LIVE SERVICE at kartsell.taxbaik.com
```

---

## 🚀 PHASE 2A: PRODUCTION BACKEND DEPLOYMENT

### Step 1: Execute Terminal 3 (RIGHT NOW)

**In PowerShell Terminal 3:**
```powershell
cd C:\Job_Roomz\KArtSell.Aegis
.\scripts\DEPLOY_PRODUCTION_NOW.ps1
```

**What This Does:**
```
1. Publishes backend code (Release mode)
2. Creates /publish/ directory with binaries
3. Runs health checks (5/5)
4. Runs smoke tests (5/5)
5. Verifies backend ready

Expected Output:
  ✅ Build: SUCCESS
  ✅ Health Checks: 5/5 PASS
  ✅ Smoke Tests: 5/5 PASS
  ✅ PRODUCTION READY
  
Time: ~30-60 minutes
```

### Step 2: Deploy Backend Binaries to Production Server

**On your production server (Linux/Windows Server):**
```bash
# Create application directory
mkdir -p /opt/kartsell/

# Copy published binaries
scp -r publish/* user@production-server:/opt/kartsell/

# Or if using Windows:
# Copy-Item -Path "publish\*" -Destination "\\production-server\c$\kartsell\" -Recurse

# Set permissions (Linux)
chmod -R 755 /opt/kartsell/
chown -R kartsell:kartsell /opt/kartsell/
```

### Step 3: Start Backend Service

**Option A: Direct Execution (Testing)**
```bash
cd /opt/kartsell/
./KArtSell.Host --configuration Release
# Or on Windows:
KArtSell.Host.exe --configuration Release
```

**Option B: Systemd Service (Production)**
```ini
# File: /etc/systemd/system/kartsell-api.service
[Unit]
Description=K-ArtSell API Service
After=network.target

[Service]
Type=simple
User=kartsell
WorkingDirectory=/opt/kartsell/
ExecStart=/opt/kartsell/KArtSell.Host
Restart=on-failure
RestartSec=10

[Install]
WantedBy=multi-user.target
```

```bash
# Enable and start
sudo systemctl enable kartsell-api.service
sudo systemctl start kartsell-api.service

# Verify
sudo systemctl status kartsell-api.service
# Expected: active (running)
```

**Verification:**
```bash
# Check if backend is running on port 5002
curl http://localhost:5002/health
# Expected: 200 OK, {"status":"healthy"}
```

---

## 🚀 PHASE 2B: FRONTEND BUILD & DEPLOYMENT

### Step 1: Build Frontend (Local)

**On your development machine (same where Terminal 2 ran):**
```bash
cd C:\Job_Roomz\KArtSell.Aegis\frontend

# Install dependencies
pnpm install --frozen-lockfile

# Type checking
pnpm typecheck

# Build for production
pnpm build

# Expected output:
# ✓ 123 modules transformed
# dist/index.html                   0.50 kB
# dist/assets/app-abc123.js       145.23 kB
# dist/assets/style-def456.css     23.45 kB
```

### Step 2: Deploy Frontend to Production Server

**Copy built frontend to Nginx root:**
```bash
# Create frontend directory
mkdir -p /var/www/kartsell/frontend

# Copy dist files
scp -r frontend/dist/* user@production-server:/var/www/kartsell/frontend/

# Set permissions
sudo chown -R www-data:www-data /var/www/kartsell/frontend/
sudo chmod -R 755 /var/www/kartsell/frontend/
```

---

## 🚀 PHASE 2C: NGINX CONFIGURATION & STARTUP

### Step 1: Create Nginx Configuration

**File: `/etc/nginx/sites-available/kartsell`**
```nginx
# HTTP redirect to HTTPS
server {
    listen 80;
    server_name kartsell.taxbaik.com;
    return 301 https://$server_name$request_uri;
}

# HTTPS server
server {
    listen 443 ssl http2;
    server_name kartsell.taxbaik.com;
    
    # SSL/TLS Certificates
    ssl_certificate /etc/letsencrypt/live/kartsell.taxbaik.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/kartsell.taxbaik.com/privkey.pem;
    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_ciphers HIGH:!aNULL:!MD5;
    
    # Logging
    access_log /var/log/nginx/kartsell-access.log;
    error_log /var/log/nginx/kartsell-error.log;
    
    # ════════════════════════════════════════════════════════════
    # Route 1: Frontend (Root /)
    # ════════════════════════════════════════════════════════════
    location / {
        root /var/www/kartsell/frontend;
        try_files $uri /index.html;
        expires 1h;
        add_header Cache-Control "public, max-age=3600";
    }
    
    # ════════════════════════════════════════════════════════════
    # Route 2: Static Assets
    # ════════════════════════════════════════════════════════════
    location ~* \.(js|css|png|jpg|jpeg|gif|ico|svg|woff|woff2)$ {
        root /var/www/kartsell/frontend;
        expires 30d;
        add_header Cache-Control "public, max-age=2592000";
    }
    
    # ════════════════════════════════════════════════════════════
    # Route 3: API (Proxy to backend)
    # ════════════════════════════════════════════════════════════
    location /api/ {
        proxy_pass http://localhost:5002/;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Forwarded-Host $server_name;
        
        proxy_connect_timeout 60s;
        proxy_send_timeout 60s;
        proxy_read_timeout 60s;
        proxy_buffering on;
        
        # WebSocket support
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}
```

### Step 2: Enable Nginx Configuration

```bash
# Create symbolic link
sudo ln -s /etc/nginx/sites-available/kartsell /etc/nginx/sites-enabled/kartsell

# Test configuration
sudo nginx -t
# Expected: nginx: configuration file test is successful

# Reload Nginx
sudo systemctl reload nginx

# Or if starting fresh:
sudo systemctl start nginx
sudo systemctl enable nginx
```

## 🧪 PHASE 2D: COMPLETE INTEGRATION VERIFICATION

### Test 1: Frontend Loads
```bash
curl -I https://kartsell.taxbaik.com/
# Expected: HTTP/2 200
# Content-Type: text/html
```

**In Browser:**
```
Open: https://kartsell.taxbaik.com/
Expected: Vue app loads, no errors in console (F12)
```

### Test 2: API Responds
```bash
curl https://kartsell.taxbaik.com/api/health
# Expected: 200 OK
# {"status":"healthy"}
```

### Test 3: Frontend → API Communication

**In Browser (https://kartsell.taxbaik.com):**
1. Open DevTools (F12)
2. Go to Network tab
3. Perform action in UI (load data)
4. Verify requests appear:
   - Request: GET /api/internal/v1/...
   - Status: 200
   - Response: Valid JSON

### Test 4: End-to-End Data Flow

```bash
# Create test data
curl -X POST https://kartsell.taxbaik.com/api/internal/v1/test \
  -H "Content-Type: application/json" \
  -H "X-KArtSell-User: test-user" \
  -H "X-KArtSell-Role: Admin" \
  -d '{"test":"data"}'

# Verify in frontend UI
# (Open browser, check if data appears)

# Verify in database
# (Query: SELECT * FROM test_table;)
```

### Test 5: Monitoring & Logs

```bash
# Frontend logs
tail -f /var/log/nginx/kartsell-access.log

# Backend logs
tail -f /opt/kartsell/logs/host-*.log

# Database logs
tail -f /var/log/postgresql/postgresql.log
```

## 🎯 SUCCESS CRITERIA

### All Must Pass
```
✅ curl https://kartsell.taxbaik.com/ → 200 (Frontend)
✅ curl https://kartsell.taxbaik.com/api/health → 200 (API)
✅ Browser load: NO CORS errors
✅ Frontend → API requests: Work seamlessly
✅ Data persistence: Create/Read/Update works
✅ Monitoring: Logs collecting
✅ Phase 1: Still running (independent)
```

### If Any Fails
```
