## 🎯 OVERVIEW

### What Is This?

A secure web-based admin panel at `https://discord-bot.firefrostgaming.com/admin` where Holly can:
- Log in using her Discord account (no passwords to remember)
- Update Discord role mappings for all 10 subscription tiers
- View bot status and recent webhook events
- Save changes instantly (no SSH access needed)

### The Problem We Solved

**Before:**
- Discord bot role mappings were hardcoded in `bot.js`
- Holly had to give Michael the role IDs via Discord/email
- Michael had to SSH into Command Center to update the file
- Michael had to restart the bot manually
- Holly waited for Michael's availability

**After:**
- Holly logs into web panel with Discord OAuth
- Holly updates role IDs in a simple form
- Changes save instantly (in-memory update, no restart)
- Config written atomically to disk with backup
- Role IDs validated against Discord API before saving
- Audit log posted to Discord channel

**Result:** Holly is independent, Michael isn't the bottleneck.

---

## 🏗️ ARCHITECTURE

### Design Principles (Thanks to Gemini)

This architecture was designed in consultation with Gemini (Google AI) and follows production best practices:

**1. Security First**
- Dedicated Linux user (`firefrost-bot`) - NOT root
- Discord OAuth2 authentication (no password management)
- Whitelist authorization (only Holly + Michael's Discord IDs)
- HTTPS via Nginx + Let's Encrypt
- CSRF protection on admin forms

**2. Zero Downtime**
- Configuration loaded into memory on startup
- Updates modify in-memory config immediately
- No bot restart required
- Atomic disk writes (no corruption)
- Backup of last-known-good config

**3. Simplicity**
- Single Node.js/Express app (webhook + admin in one)
- JSON config file (no database needed for 10 key-value pairs)
- Validation: Regex check + Discord API verification
- In-memory webhook logs (last 50 events, rotating)

**4. Auditability**
- Discord `#bot-audit-logs` channel for config changes
- Backup config file for disaster recovery
- Systemd journal logs everything

### Tech Stack

**Backend:**
- Node.js 18+
- Express.js (web server)
- discord.js (Discord API)
- Passport.js (Discord OAuth2)
- write-file-atomic (safe config saves)

**Frontend:**
- Simple HTML/CSS/JavaScript
- Vanilla JS with `fetch()` API
- No frameworks (keep it simple for Holly)
- Fire/Frost branding

**Infrastructure:**
- Command Center (63.143.34.217)
- Nginx reverse proxy
- Let's Encrypt SSL
- Systemd service

---

## 🤔 WHY WE BUILT THIS

### Holly's Perspective

**Before:**
- "I created Discord roles, now I need to wait for Michael to update the bot."
- "I want to test if the role IDs work, but I can't update them myself."
- "If I make a typo in the role ID I give Michael, we have to repeat the whole process."

**After:**
- "I created Discord roles, I'll paste the IDs into the admin panel."
- "I can test immediately - if a role ID is wrong, the panel tells me before saving."
- "I'm independent - I can iterate and test without waiting."

### Michael's Perspective

**Before:**
- "Holly needs role IDs updated. I have to stop what I'm doing, SSH in, edit the file, restart the bot."
- "If I make a typo, Holly has to tell me, and I have to repeat the process."
- "I'm the single point of failure for a 5-minute task."

**After:**
- "Holly handles her own role mappings. I only get involved if something breaks."
- "The admin panel validates role IDs before saving, so typos get caught automatically."
- "I set this up once, Holly uses it forever."

## ✅ PART 1: PREREQUISITES

### Before You Start

**On Command Center (63.143.34.217):**
- [ ] Discord bot already running (from Subscription Automation Guide Part 1)
- [ ] Bot accessible at `https://webhook.firefrostgaming.com/webhook/paymenter`
- [ ] Node.js 18+ installed
- [ ] Nginx installed and configured
- [ ] SSL certificate (Let's Encrypt)

**Discord Requirements:**
- [ ] Discord bot application exists
- [ ] Bot is in Firefrost Gaming Discord server
- [ ] You have bot token
- [ ] You have Guild ID (server ID)
- [ ] You have Holly's Discord user ID
- [ ] You have Michael's Discord user ID

**DNS Configuration:**
- [ ] `discord-bot.firefrostgaming.com` A record → 63.143.34.217
- [ ] Cloudflare proxy: OFF (orange cloud = OFF)

---

## 🔧 PART 2: CREATE DEDICATED BOT USER

**CRITICAL SECURITY FIX: Do NOT run the bot as root.**

Running Node.js as root is a major security risk. If any npm package has a vulnerability, an attacker gets full control of Command Center.

### Step 1: Create System User

SSH to Command Center:

```bash
ssh root@63.143.34.217
```

Create dedicated user:

```bash
# Create system user (no login shell, no home directory login)
sudo useradd -r -s /bin/false firefrost-bot

# Verify user was created
id firefrost-bot
# Should show: uid=... gid=... groups=...
```

### Step 2: Transfer Ownership

Transfer bot directory to new user:

```bash
# Change ownership of bot directory
sudo chown -R firefrost-bot:firefrost-bot /opt/firefrost-discord-bot

# Verify permissions
ls -la /opt/firefrost-discord-bot
# Should show: drwxr-xr-x ... firefrost-bot firefrost-bot
```

### Step 3: Update Systemd Service

Edit the service file:

```bash
sudo nano /etc/systemd/system/firefrost-discord-bot.service
```

**Replace contents with this complete configuration:**

```ini
[Unit]
Description=Firefrost Discord Bot & Admin Panel
After=network.target

[Service]
Type=simple
User=firefrost-bot
Group=firefrost-bot
WorkingDirectory=/opt/firefrost-discord-bot
ExecStart=/usr/bin/node bot.js
Restart=on-failure
RestartSec=10
Environment=NODE_ENV=production

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

**What this configuration does:**
- **After=network.target:** Waits for network before starting
- **User/Group=firefrost-bot:** Runs as dedicated user (NOT root)
- **Restart=on-failure:** Auto-restarts if bot crashes
- **RestartSec=10:** Waits 10 seconds before restart
- **NODE_ENV=production:** Sets production environment

Save and exit: `Ctrl+X`, `Y`, `Enter`

Reload and restart:

```bash
# Reload systemd
sudo systemctl daemon-reload

# Restart bot with new user
sudo systemctl restart firefrost-discord-bot

# Verify it's running
sudo systemctl status firefrost-discord-bot
# Should show: Active: active (running)

# Check logs
sudo journalctl -u firefrost-discord-bot -n 50
# Should show no permission errors
```

**If you see permission errors:** Fix file permissions and retry.

---

## 🔐 PART 3: SET UP DISCORD OAUTH2 APPLICATION

### Step 1: Discord Developer Portal

1. Go to: https://discord.com/developers/applications
2. Select your **Firefrost Subscription Manager** bot application
3. Click **OAuth2** in left sidebar

### Step 2: Add Redirect URLs

Under **Redirects**, add:

**For local testing (optional):**
```
http://localhost:3100/auth/discord/callback
```

**For production (required):**
```
https://discord-bot.firefrostgaming.com/auth/discord/callback
```

Click **Save Changes**.

### Step 3: Copy Credentials

**Copy these values (you'll need them for .env file):**

- **Client ID:** (18-digit number under OAuth2 General)
- **Client Secret:** Click "Reset Secret" → Copy the new secret

**⚠️ IMPORTANT:** The Client Secret only shows once. Copy it immediately and save to Vaultwarden.

### Step 4: Get Discord User IDs

**Holly's Discord ID:**
1. In Discord, right-click Holly's username
2. Click "Copy User ID"
3. Paste somewhere safe (e.g., `123456789012345678`)

**Michael's Discord ID:**
1. Same process for Michael's account
2. Paste somewhere safe

**Note:** If "Copy User ID" doesn't appear, enable Developer Mode:
- Discord Settings → Advanced → Developer Mode (toggle ON)

---

## 💻 PART 4: DEPLOY BACKEND CODE

### Overview

Deploy the complete Discord bot backend with OAuth2 authentication, in-memory config management, atomic file writes, role validation, webhook logging, and Discord audit log embeds.

**Architecture designed by:** Gemini (Google AI)  
**Implementation:** Production-ready Node.js/Express/Discord.js application

---

### Step 1: Install Dependencies

SSH to Command Center:

```bash
ssh root@63.143.34.217
cd /opt/firefrost-discord-bot
```

Install required npm packages:

```bash
npm install express express-session passport passport-discord write-file-atomic dotenv discord.js
```

**What these packages do:**
- **express:** Web server framework
- **express-session:** Session management for OAuth
- **passport:** Authentication framework
- **passport-discord:** Discord OAuth2 strategy
- **write-file-atomic:** Safe config file writes (prevents corruption)
- **dotenv:** Environment variable management
- **discord.js:** Discord API client library

---

### Step 2: Create Environment Variables File

**Option A: Use the template (recommended)**

Create `.env.template` first for reference:

```bash
nano /opt/firefrost-discord-bot/.env.template
```

**Paste this complete template:**

```env
# ==========================================
# FIREFROST COMMAND CENTER - ENVIRONMENT VARIABLES
# Copy this file to .env and fill in the values.
# DO NOT commit the actual .env file to version control.
# ==========================================

# 1. Server Configuration
# ------------------------------------------
# production or development
NODE_ENV=production
# The internal port the Node app runs on (Nginx proxies to this)
PORT=3100
# A long, random string used to encrypt web session cookies
SESSION_SECRET=YOUR_SUPER_SECRET_RANDOM_STRING_HERE

# 2. Discord Bot Core
# ------------------------------------------
# The actual token for the Firefrost Discord Bot (from Discord Developer Portal -> Bot)
DISCORD_TOKEN=YOUR_BOT_TOKEN_HERE
# The ID of the Firefrost Gaming Discord Server
GUILD_ID=YOUR_SERVER_GUILD_ID_HERE

# 3. Discord OAuth2 (Web Login)
# ------------------------------------------
# From Discord Developer Portal -> OAuth2 -> General
DISCORD_CLIENT_ID=YOUR_OAUTH_CLIENT_ID_HERE
DISCORD_CLIENT_SECRET=YOUR_OAUTH_CLIENT_SECRET_HERE
# The URL Discord will redirect to after login (Must match the one added in the Dev Portal exactly)
CALLBACK_URL=https://discord-bot.firefrostgaming.com/auth/discord/callback

# 4. Security & Auditing
# ------------------------------------------
# Comma-separated list of Discord User IDs who are allowed to log in (Holly and Michael)
# Example: 123456789,987654321
ALLOWED_ADMINS=HOLLYS_ID,MICHAELS_ID
# The ID of the private #bot-audit-logs channel where config change embeds are sent
AUDIT_CHANNEL_ID=YOUR_AUDIT_CHANNEL_ID_HERE
```

Save and exit: `Ctrl+X`, `Y`, `Enter`

**Now create the actual .env file:**

```bash
# Copy template to .env
cp /opt/firefrost-discord-bot/.env.template /opt/firefrost-discord-bot/.env

# Edit .env file
nano /opt/firefrost-discord-bot/.env
```

**Option B: Create .env directly (alternative)**

If you didn't create the template, create `.env` directly:

```bash
nano /opt/firefrost-discord-bot/.env
```

**Paste the template above and fill in YOUR values below.**

---

**How to fill in each value:**

**DISCORD_TOKEN:**
- Go to Discord Developer Portal → Your Bot → Bot → Token
- Click "Reset Token" → Copy

**DISCORD_CLIENT_ID:**
- Discord Developer Portal → Your Bot → OAuth2 → Client ID
- Copy the 18-digit number

**DISCORD_CLIENT_SECRET:**
- Discord Developer Portal → Your Bot → OAuth2 → Client Secret
- Click "Reset Secret" → Copy (shows only once!)

**GUILD_ID:**
- In Discord, right-click your server icon → Copy ID
- Requires Developer Mode enabled (User Settings → Advanced → Developer Mode)

**CALLBACK_URL:**
- Leave as: `https://discord-bot.firefrostgaming.com/auth/discord/callback`
- Must match exactly what you added in Discord Developer Portal

**SESSION_SECRET:**
- Generate random string: `openssl rand -base64 48`
- Copy output and paste here

**ALLOWED_ADMINS:**
- Holly's Discord ID: Right-click Holly's username → Copy ID
- Michael's Discord ID: Right-click Michael's username → Copy ID
- Format: `123456789012345678,987654321098765432` (comma-separated, no spaces)

**AUDIT_CHANNEL_ID:**
- Create `#bot-audit-logs` channel in Discord (private, restricted to Michael, Holly, bot)
- Right-click channel → Copy ID

**NODE_ENV:**
- Leave as: `production`

**PORT:**
- Leave as: `3100` (or change if you need different port)

Save and exit: `Ctrl+X`, `Y`, `Enter`

---

### Step 3: Set Environment File Permissions

**CRITICAL:** `.env` file contains secrets and must be read-only for bot user:

```bash
# Make .env readable only by firefrost-bot user
chmod 600 /opt/firefrost-discord-bot/.env
chown firefrost-bot:firefrost-bot /opt/firefrost-discord-bot/.env

# Verify permissions
ls -la /opt/firefrost-discord-bot/.env
# Should show: -rw------- firefrost-bot firefrost-bot
```

---

### Step 4: Deploy Complete bot.js

**Back up existing bot.js (if it exists):**

```bash
# Only if you have an existing bot.js
cp /opt/firefrost-discord-bot/bot.js /opt/firefrost-discord-bot/bot.js.backup
```

Create new bot.js:

```bash
nano /opt/firefrost-discord-bot/bot.js
```

**Paste the complete production-ready code below.**

```

Save and exit: `Ctrl+X`, `Y`, `Enter`

---

### Step 5: Set File Permissions

Ensure firefrost-bot user owns the bot.js file:

```bash
chown firefrost-bot:firefrost-bot /opt/firefrost-discord-bot/bot.js
chmod 644 /opt/firefrost-discord-bot/bot.js
```

---

### Step 6: Create Discord Audit Log Channel

Before starting the bot, create the audit log channel in Discord:

1. Open Discord server
2. Create new channel: `#bot-audit-logs`
3. Set channel to **Private**
4. Add members: Michael, Holly, Firefrost Subscription Manager (bot)
5. Right-click channel → Copy ID
6. Add channel ID to `.env` file (`AUDIT_CHANNEL_ID`)

---

### Step 7: Restart Bot Service

Apply all changes:

```bash
# Restart bot with new code
sudo systemctl restart firefrost-discord-bot

# Check status
sudo systemctl status firefrost-discord-bot
# Should show: Active: active (running)

# View logs to verify startup
sudo journalctl -u firefrost-discord-bot -n 50
```

**Expected log output:**

```
Bot logged in as Firefrost Subscription Manager#1234
Firefrost Command Center running on port 3100
```

If you see these messages, backend deployment is successful! ✅

## 🎨 PART 5: DEPLOY FRONTEND CODE

### Overview

The frontend provides Holly with a clean, mobile-friendly interface to manage Discord role mappings. It features:
- Discord OAuth login flow
- 10 product → role ID input fields
- Per-row save buttons with validation feedback
- Bot status indicator
- Recent webhook logs table with manual refresh
- Fire/Frost branding (#FF6B35 / #4ECDC4)

**Tech:** Vanilla HTML/CSS/JavaScript (no frameworks)

**Design by:** Gemini (Google AI)

---

### Step 1: Create Public Directory

SSH to Command Center:

```bash
ssh root@63.143.34.217
cd /opt/firefrost-discord-bot

# Create public directory
mkdir -p public

# Set ownership
chown firefrost-bot:firefrost-bot public
```

---

### Step 2: Enable Static File Serving

Edit `bot.js` to serve static files:

```bash
nano /opt/firefrost-discord-bot/bot.js
```

Add this line after `app.use(express.json());`:

```javascript
app.use(express.static('public'));
```

**Full context in bot.js:**

```javascript
const app = express();
app.use(express.json()); // For parsing application/json
app.use(express.static('public')); // <-- ADD THIS LINE
```

Save and exit.

---

### Step 3: Create index.html

Create the main HTML file:

```bash
nano /opt/firefrost-discord-bot/public/index.html
```

**Paste this complete HTML:**

```html
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

            </section>

            <section class="logs-section">
                <div class="logs-header">

                </div>
                <div class="table-container">
                    <table id="logs-table">
                        <thead>
                            <tr>
                                <th>Time</th>
                                <th>Product ID</th>
                                <th>Status</th>
                            </tr>
                        </thead>
                        <tbody id="logs-body">
                        </tbody>
                    </table>
                </div>
            </section>
        </main>
    </div>

    <script src="app.js"></script>
</body>
</html>
```

Save and exit: `Ctrl+X`, `Y`, `Enter`

### Step 5: Create app.js

Create the JavaScript application logic:

```bash
nano /opt/firefrost-discord-bot/public/app.js
```

**Paste this complete JavaScript:**

```javascript
// Product definitions for the UI
const PRODUCTS = [
    { id: '2', name: 'The Awakened', type: '$1 one-time' },
    { id: '3', name: 'Fire Elemental', type: '$5/mo' },

    { id: '10', name: 'Frost Legend', type: '$20/mo' },
    { id: '11', name: 'Sovereign', type: '$499 one-time' }
];

document.addEventListener('DOMContentLoaded', initApp);

async function initApp() {
    try {
        // Try to fetch config. If we get a 401, they need to log in.
        const response = await fetch('/api/config');
        
        if (response.status === 401) {
            document.getElementById('login-view').classList.remove('hidden');
            return;
        }

        if (response.ok) {

        // Success UX
        btn.textContent = 'Saved!';
        btn.style.backgroundColor = 'var(--success)';
        setTimeout(() => {
            btn.textContent = 'Save';
            btn.style.backgroundColor = 'var(--fire)';
            btn.disabled = false;
        }, 2000);

    } catch (error) {

        `;
        tbody.appendChild(tr);
    });
}
```

Save and exit: `Ctrl+X`, `Y`, `Enter`

### Step 6: Set File Permissions

Ensure firefrost-bot user owns all frontend files:

```bash
chown -R firefrost-bot:firefrost-bot /opt/firefrost-discord-bot/public
chmod 644 /opt/firefrost-discord-bot/public/*
```

---

### Step 7: Add Webhook Logging Endpoint

Edit `bot.js` to add the `/api/logs` endpoint:

```bash
nano /opt/firefrost-discord-bot/bot.js
```

**Add this endpoint after the `/api/config` routes:**

```javascript
// Webhook Logs Endpoint
app.get('/api/logs', isAuthenticated, (req, res) => {
    res.json(webhookLogs);
});
```

**Also update your webhook handler to log events:**

In your `POST /webhook/paymenter` handler, add logging:

```javascript
app.post('/webhook/paymenter', async (req, res) => {
    try {
        const { productId, userId } = req.body; // Adjust based on actual Paymenter payload
        
        // Log the webhook event
        webhookLogs.push({
            timestamp: new Date().toISOString(),
            productId: productId,
            userId: userId,
            success: true,
            status: 'Success'
        });
        
        // Keep only last 50 logs (circular buffer)
        if (webhookLogs.length > 50) {
            webhookLogs.shift();
        }
        
        // Your existing webhook logic here...
        
        res.json({ success: true });
    } catch (error) {
        // Log failure
        webhookLogs.push({
            timestamp: new Date().toISOString(),
            productId: req.body.productId || 'unknown',
            success: false,
            status: 'Failed',
            error: error.message
        });
        
        res.status(500).json({ error: error.message });
    }
});
```

Save and exit.

---

### Step 8: Restart Bot

Apply all frontend changes:

```bash
# Restart bot service
sudo systemctl restart firefrost-discord-bot

# Check status
sudo systemctl status firefrost-discord-bot

# View logs
sudo journalctl -u firefrost-discord-bot -n 50
```

Should show: `Active: active (running)` with no errors.

---

### Step 9: Test Frontend Access

**Before OAuth is set up:**

1. Open browser
2. Go to: `http://localhost:3100` (from Command Center)
3. Should see login screen with "🔥 Firefrost Command ❄️"

**Note:** Full testing requires OAuth setup (Part 3) and Nginx/SSL (Part 6).

---

## 🎨 FRONTEND FEATURES

### Login Screen
- Clean card design with Fire/Frost branding
- "Login with Discord" button
- Redirects to Discord OAuth

### Dashboard
- **Navbar:** Bot status indicator + logout button
- **Role Mappings Section:**
  - 10 product rows (Awakened → Sovereign)
  - Each row: Product name, tier price, role ID input, Save button
  - Per-row save (instant feedback)
  - Inline error messages
- **Webhook Logs Section:**
  - Table: Time, Product ID, Status
  - Manual refresh button
  - Last 50 events

### Mobile Responsive
- Flexbox layout adapts to phone screens
- Input fields stack vertically on mobile
- Navbar collapses to single column
- Touch-friendly button sizes

---

## 🎨 UI/UX DECISIONS (BY GEMINI)

**Save Per Row (Not "Save All"):**
- If one role ID is invalid, others aren't blocked
- Instant, precise feedback on which field failed
- Holly can save valid ones, fix invalid ones, retry

**Validate on Save (Not on Blur):**
- Prevents API spam while typing
- Explicit user action required
- Clear visual feedback (button changes)

**Inline Errors:**
- Error appears directly under failed field
- Holly knows exactly what to fix
- Color-coded: red = error, green = success

**Manual Log Refresh:**
- Prevents auto-refresh layout shifting
- Lower browser memory usage
- Holly controls when to check logs

---

**Frontend deployment complete!** ✅

Next: Configure Nginx & SSL (Part 6)

---

## 🌐 PART 6: CONFIGURE NGINX & SSL

### Overview

Configure Nginx reverse proxy to forward HTTPS traffic to the Node.js app, then secure with Let's Encrypt SSL certificate.

**What this does:**
- Nginx listens on port 80 (HTTP) and 443 (HTTPS)
- Forwards traffic to Node.js app on localhost:3100
- Let's Encrypt provides free SSL certificate
- Auto-renews certificate every 90 days

---

### Step 1: Create Nginx Configuration

Create new site config:

```bash
sudo nano /etc/nginx/sites-available/discord-bot.firefrostgaming.com
```

**Paste this complete configuration:**

```nginx
server {
    listen 80;
    server_name discord-bot.firefrostgaming.com;

    location / {
        proxy_pass http://localhost:3100;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        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_cache_bypass $http_upgrade;
    }
}
```

**What these headers do:**
- **X-Real-IP:** Passes client's real IP to Node.js (not Nginx's IP)
- **X-Forwarded-For:** Shows full proxy chain
- **X-Forwarded-Proto:** Tells app if request was HTTP or HTTPS
- **Upgrade/Connection:** Required for WebSocket support (future-proofing)

Save and exit: `Ctrl+X`, `Y`, `Enter`

---

### Step 2: Enable Site

Create symlink to enable the site:

```bash
sudo ln -s /etc/nginx/sites-available/discord-bot.firefrostgaming.com /etc/nginx/sites-enabled/
```

Test Nginx configuration for syntax errors:

```bash
sudo nginx -t
```

**Expected output:**
```
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
```

If test passes, reload Nginx:

```bash
sudo systemctl reload nginx
```

---

### Step 3: Verify HTTP Access (Before SSL)

**Test that Nginx is forwarding correctly:**

1. Open browser
2. Go to: `http://discord-bot.firefrostgaming.com`
3. Should see admin panel login screen

**If you get an error:**
- Check bot is running: `sudo systemctl status firefrost-discord-bot`
- Check Nginx logs: `sudo tail -f /var/log/nginx/error.log`
- Verify DNS: `dig discord-bot.firefrostgaming.com` (should show 63.143.34.217)

---

### Step 4: Install Certbot (If Not Already Installed)

Check if Certbot is installed:

```bash
certbot --version
```

**If not installed:**

```bash
# Install Certbot and Nginx plugin
sudo apt update
sudo apt install certbot python3-certbot-nginx -y
```

---

### Step 5: Obtain SSL Certificate

Run Certbot with Nginx plugin:

```bash
sudo certbot --nginx -d discord-bot.firefrostgaming.com
```

**Certbot will ask:**

1. **Email address:** (for renewal notices)
   - Enter Michael's email or devops@firefrostgaming.com

2. **Terms of Service:** (A)gree
   - Type `A` and press Enter

3. **Share email with EFF?** (Y)es or (N)o
   - Your choice (either is fine)

**Certbot will automatically:**
- ✅ Validate domain ownership (checks DNS points to this server)
- ✅ Obtain SSL certificate from Let's Encrypt
- ✅ Modify Nginx config to enable HTTPS (port 443)
- ✅ Add HTTP → HTTPS redirect
- ✅ Set up auto-renewal (certificate renews every 90 days)

**Expected output:**
```
Successfully received certificate.
Certificate is saved at: /etc/letsencrypt/live/discord-bot.firefrostgaming.com/fullchain.pem
Key is saved at:         /etc/letsencrypt/live/discord-bot.firefrostgaming.com/privkey.pem
...
Congratulations! You have successfully enabled HTTPS on https://discord-bot.firefrostgaming.com
```

---

### Step 6: Verify HTTPS Access

Test SSL is working:

1. Open browser
2. Go to: `https://discord-bot.firefrostgaming.com`
3. Should see:
   - ✅ Green padlock icon (valid SSL)
   - ✅ Admin panel login screen
   - ✅ "Login with Discord" button

**Test HTTP redirect:**

1. Go to: `http://discord-bot.firefrostgaming.com` (HTTP, not HTTPS)
2. Should automatically redirect to HTTPS version
3. URL bar should show `https://discord-bot.firefrostgaming.com`

---

### Step 7: Verify Auto-Renewal

Certbot sets up automatic renewal via systemd timer.

**Check renewal timer status:**

```bash
sudo systemctl status certbot.timer
```

Should show: `Active: active (waiting)`

**Test renewal (dry run, doesn't actually renew):**

```bash
sudo certbot renew --dry-run
```

Should show: `Congratulations, all simulated renewals succeeded`

**Certificate auto-renews:** Every 90 days, systemd timer runs `certbot renew` automatically.

---

### Step 8: View Final Nginx Configuration

Certbot modified your Nginx config to add SSL. View the changes:

```bash
cat /etc/nginx/sites-available/discord-bot.firefrostgaming.com
```

**You'll now see TWO server blocks:**

1. **HTTP (port 80):** Redirects to HTTPS
2. **HTTPS (port 443):** Proxies to Node.js with SSL

**Example of Certbot's additions:**

```nginx
server {
    listen 443 ssl;
    server_name discord-bot.firefrostgaming.com;
    
    ssl_certificate /etc/letsencrypt/live/discord-bot.firefrostgaming.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/discord-bot.firefrostgaming.com/privkey.pem;
    include /etc/letsencrypt/options-ssl-nginx.conf;
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;
    
    # ... your original location / block ...
}

server {
    listen 80;
    server_name discord-bot.firefrostgaming.com;
    return 301 https://$server_name$request_uri;
}
```

---

### Step 9: Security Headers (Optional but Recommended)

Add security headers to HTTPS server block:

```bash
sudo nano /etc/nginx/sites-available/discord-bot.firefrostgaming.com
```

**Add these lines inside the `server { listen 443 ssl; ... }` block:**

```nginx
    # Security Headers
    add_header X-Frame-Options "SAMEORIGIN" always;
    add_header X-Content-Type-Options "nosniff" always;
    add_header X-XSS-Protection "1; mode=block" always;
    add_header Referrer-Policy "strict-origin-when-cross-origin" always;
```

**What these do:**
- **X-Frame-Options:** Prevents clickjacking (site can't be embedded in iframe)
- **X-Content-Type-Options:** Prevents MIME-type sniffing attacks
- **X-XSS-Protection:** Enables browser XSS filter
- **Referrer-Policy:** Controls what info is sent in Referer header

Save, test, reload:

```bash
sudo nginx -t
sudo systemctl reload nginx
```

---

## ✅ NGINX & SSL COMPLETE

**You now have:**
- ✅ Nginx reverse proxy forwarding to Node.js
- ✅ Valid SSL certificate from Let's Encrypt
- ✅ HTTPS enforced (HTTP redirects to HTTPS)
- ✅ Auto-renewal configured (every 90 days)
- ✅ Security headers enabled
- ✅ Admin panel accessible at `https://discord-bot.firefrostgaming.com`

## 👥 PART 7: HOLLY'S USAGE GUIDE

**This section is for Holly - how to use the admin panel.**

### When You Need This

Use the admin panel when:
- ✅ You've created new Discord roles
- ✅ You need to update role IDs in the bot
- ✅ You want to test if role IDs are correct
- ✅ You need to change a role mapping

### Step 1: Log In

1. Open browser (Chrome, Firefox, Edge)
2. Go to: `https://discord-bot.firefrostgaming.com/admin`
3. Click **"Login with Discord"** button
4. Discord OAuth page appears
5. Click **"Authorize"**
6. You're redirected back to admin panel

**Note:** You only need to log in once - browser remembers you via session cookie.

### Step 2: View Current Mappings

Admin panel shows current role mappings:

```
Product 2 (The Awakened):      [123456789012345678]
Product 3 (Fire Elemental):    [234567890123456789]
Product 4 (Frost Elemental):   [345678901234567890]
...
```

These are the Discord role IDs currently in use.

### Step 3: Update Role IDs

**When you create Discord roles:**

1. In Discord, go to Server Settings → Roles
2. Right-click a role → Copy ID
3. Paste into appropriate field in admin panel
4. Repeat for all 10 roles

**Example:**

You created "🔥 Fire Elemental" role in Discord:
1. Right-click role → Copy ID → `987654321098765432`
2. In admin panel, find "Product 3 (Fire Elemental)" field
3. Paste: `987654321098765432`

### Step 4: Save Changes

1. Click **"Save All Changes"** button
2. Panel validates each role ID:
   - ✅ Checks format (must be 18-19 digit number)
   - ✅ Verifies role exists in Discord server
3. If validation passes:
   - ✅ Config saved to disk
   - ✅ In-memory config updated (instant effect)
   - ✅ Audit log posted to Discord `#bot-audit-logs`
   - ✅ Success message appears: "All role mappings updated!"
4. If validation fails:
   - ❌ Error message shows which role ID is invalid
   - ❌ Config NOT saved (prevents bot from breaking)
   - ❌ Fix the invalid role ID and try again

### Step 5: Test Webhook

After saving role mappings:

1. Go to Paymenter test page (ask Michael for URL)
2. Create test purchase for $5 Fire Elemental tier
3. Check Discord - does bot assign "🔥 Fire Elemental" role?
4. If yes: ✅ Role mapping works!
5. If no: ❌ Check bot logs or ask Michael

### Step 6: Logout (Optional)

Click **"Logout"** button when done.

**Note:** You can stay logged in - session expires after 24 hours.

## 🔧 TROUBLESHOOTING

### Problem: "Unauthorized" Error When Accessing Admin Panel

**Symptoms:** Can't access `/admin`, get 401 error.

**Causes:**
1. Not logged in via Discord OAuth
2. Your Discord ID isn't in `ALLOWED_ADMINS` list

**Solutions:**

**Check if logged in:**
- Clear browser cookies
- Try logging in again via "Login with Discord"

**Check whitelist:**

```bash
# On Command Center
cat /opt/firefrost-discord-bot/.env | grep ALLOWED_ADMINS
```

Should show Holly's and Michael's Discord IDs separated by comma.

**If your ID is missing:**

```bash
# Edit .env
sudo nano /opt/firefrost-discord-bot/.env

# Add your Discord ID to ALLOWED_ADMINS
ALLOWED_ADMINS=HOLLYS_ID,MICHAELS_ID,YOUR_ID

# Save and restart bot
sudo systemctl restart firefrost-discord-bot
```

---

### Problem: "Role does not exist in Discord server" Error

**Symptoms:** Valid-looking role ID rejected during save.

**Causes:**
1. Role ID is from wrong Discord server
2. Role was deleted after you copied ID
3. Bot doesn't have permission to see roles

**Solutions:**

**Verify role exists:**
1. Go to Discord Server Settings → Roles
2. Find the role
3. Right-click → Copy ID again
4. Paste fresh ID into admin panel

**Check bot permissions:**
1. Discord Server Settings → Roles
2. Find "Firefrost Subscription Manager" bot role
3. Ensure it has "Manage Roles" permission
4. Ensure bot role is ABOVE the roles it needs to assign

---

### Problem: Admin Panel Shows Old Role Mappings

**Symptoms:** You saved new IDs, but admin panel shows old ones after refresh.

**Causes:**
1. Browser cache
2. Config file didn't save
3. In-memory config didn't update

**Solutions:**

**Hard refresh browser:**
- Windows: `Ctrl + Shift + R`
- Mac: `Cmd + Shift + R`

**Check config file:**

```bash
# On Command Center
cat /opt/firefrost-discord-bot/config.json
```

Should show your latest role IDs.

**If config.json is outdated:**

```bash
# Restart bot
sudo systemctl restart firefrost-discord-bot

# Try saving again in admin panel
```

---

### Problem: OAuth Login Redirects to "Cannot GET /auth/discord/callback"

**Symptoms:** After clicking "Authorize" in Discord, get error page.

**Causes:**
1. Callback URL mismatch in Discord Developer Portal
2. Backend route not set up correctly

**Solutions:**

**Check Discord Developer Portal:**
1. Go to: https://discord.com/developers/applications
2. Select your bot app → OAuth2
3. Under Redirects, verify you have:
   `https://discord-bot.firefrostgaming.com/auth/discord/callback`
4. Save changes if missing

**Check .env file:**

```bash
cat /opt/firefrost-discord-bot/.env | grep CALLBACK_URL
```

Should match Discord Developer Portal exactly.

**Restart bot:**

```bash
sudo systemctl restart firefrost-discord-bot
```

---

### Problem: Bot Assigns Wrong Role After Config Update

**Symptoms:** Config saved successfully, but webhook assigns incorrect role.

**Causes:**
1. Product ID → Role ID mapping is wrong
2. In-memory config didn't update

**Solutions:**

**Verify mapping in admin panel:**

Product 3 should map to Fire Elemental role ID, not Frost Elemental.

**Check config.json:**

```bash
cat /opt/firefrost-discord-bot/config.json
```

Should show correct mappings.

**Restart bot (force reload):**

```bash
sudo systemctl restart firefrost-discord-bot
```

**Test webhook again.**

## 🔄 MAINTENANCE

### Regular Tasks

**Weekly:**
- Check bot logs for errors: `sudo journalctl -u firefrost-discord-bot -n 100`
- Verify SSL certificate is valid (auto-renewed by certbot)

**Monthly:**
- Review audit logs in Discord `#bot-audit-logs`
- Verify backup config exists: `ls -la /opt/firefrost-discord-bot/config.json.backup`

**As Needed:**
- Update role mappings when creating new Discord roles
- Add/remove admin users from `ALLOWED_ADMINS` in `.env`

### Backup Strategy

**Config is backed up automatically:**
- Every save creates `config.json.backup`
- Contains last-known-good configuration

**To restore from backup:**

```bash
# SSH to Command Center
cd /opt/firefrost-discord-bot

# Copy backup to active config
cp config.json.backup config.json

# Restart bot
sudo systemctl restart firefrost-discord-bot
```

### Updating Backend Code

If Gemini provides code updates:

```bash
# SSH to Command Center
cd /opt/firefrost-discord-bot

# Backup current code
cp bot.js bot.js.backup

# Edit bot.js with new code
sudo nano bot.js

# Test syntax (optional)
node --check bot.js

# Restart bot
sudo systemctl restart firefrost-discord-bot

# Check logs
sudo journalctl -u firefrost-discord-bot -n 50
```
