## Hey Gemini! 🎯

Perfect — this is exactly what we needed! The code is clean, well-structured, and production-ready. We have a few final questions to make sure we implement this correctly.

---

## QUESTION 1: Role Mapping Configuration ⭐

You asked: *"Would you like me to map out how to store the tier to Discord Role ID mapping in a configuration file?"*

**Yes please!** 

We have 6 subscription tiers that need to map to Discord roles:

| Tier Name | Price | Discord Role Name |
|-----------|-------|-------------------|
| `awakened` | $1 | The Awakened |
| `fire_elemental` | $5 | Fire Elemental |
| `frost_elemental` | $5 | Frost Elemental |
| `fire_knight` | $10 | Fire Knight |
| `frost_knight` | $10 | Frost Knight |
| `fire_master` | $15 | Fire Master |
| `frost_master` | $15 | Frost Master |
| `fire_legend` | $20 | Fire Legend |
| `frost_legend` | $20 | Frost Legend |
| `sovereign` | $50 | Sovereign |

**Questions:**
1. Should this be a JSON config file? (`config/roles.json`)
2. Or hardcoded in the code with a Map/Object?
3. Do we look up by tier name (string) or product_id (number)?
4. How do we handle the Discord role IDs? (they're long snowflake IDs like `1234567890123456789`)

**Can you provide:**
- The config file structure (if using JSON)
- The `assignDiscordRole()` function that reads this config
- How to handle role assignment failures (role doesn't exist, bot lacks permissions, etc.)

---

## QUESTION 2: The Existing `assignDiscordRole()` Function

You referenced this function in your webhook handler:
```javascript
const { assignDiscordRole } = require('../discord');
```

We have an existing Discord bot built with discord.js. Our current role assignment code looks something like this:

```javascript
// Existing code (simplified)
async function assignDiscordRole(userId, roleName) {
    const guild = client.guilds.cache.get(GUILD_ID);
    const member = await guild.members.fetch(userId);
    const role = guild.roles.cache.find(r => r.name === roleName);
    await member.roles.add(role);
}
```

**Questions:**
1. Should we modify this function to work with your tier-based system?
2. Should it take `tier` (string) and look up the role ID from config?
3. What if the user isn't in the Discord server yet? Should we:
   - Auto-invite them using `guilds.join` scope?
   - Just fail gracefully and ask them to join first?
   - Store the pending role and assign it when they join?

**Can you provide:**
- Complete `assignDiscordRole(userId, tier)` function
- Error handling for all edge cases
- Integration with the config/mapping system

---

## QUESTION 3: Discord Bot Integration

The Arbiter is already running as a Discord bot. We need to integrate your OAuth code with the existing bot instance.

**Current structure (simplified):**
```javascript
// index.js (main file)
const { Client, GatewayIntentBits } = require('discord.js');
const express = require('express');

const client = new Client({
    intents: [GatewayIntentBits.Guilds, GatewayIntentBits.GuildMembers]
});

const app = express();

client.on('ready', () => {
    console.log('Bot ready');
});

// Webhook routes go here
app.use('/webhook', require('./routes/webhook'));

client.login(process.env.DISCORD_BOT_TOKEN);
app.listen(3500);
```

**Questions:**
1. How do we pass the `client` instance to the `assignDiscordRole()` function?
2. Should we export `client` from the main file?
3. Or pass it as a parameter?
4. Any setup required in the bot's ready event?

**Can you provide:**
- How to structure the Discord bot integration
- Where to initialize the client
- How routes access the bot instance

---

## QUESTION 4: Cleanup & Maintenance

**Token Expiration Cleanup:**
Your table has tokens that expire after 24 hours, but they stay in the database forever.

**Questions:**
1. Should we run a cleanup job to delete old tokens?
2. If yes, how often? (Daily? Weekly?)
3. Should we use a cron job or a simple setInterval?

**Can you provide:**
- Cleanup function code
- How to schedule it (cron, setInterval, or manual)

**Database Maintenance:**
1. Do we need to add indexes for performance?
2. Should we periodically vacuum the SQLite database?
3. Any other maintenance tasks?

---

## QUESTION 5: Error Messages & User Experience

**Success Page:**
Your callback currently sends: `"Success! Your Discord account is linked. You may close this window."`

**Questions:**
1. Should we make this a proper HTML page with branding?
2. Should we redirect them to Discord or back to the website?
3. Should we show them which role they received?

**Error Pages:**
For various errors (expired link, invalid state, API failure), should we:
1. Create branded HTML error pages?
2. Or keep simple text responses?
3. Should we provide recovery instructions?

**Can you provide:**
- Sample success HTML page (if recommended)
- Sample error HTML page (if recommended)
- Best practices for user messaging

---

## QUESTION 6: Webhook Security

Currently the webhook endpoint has no authentication.

**Questions:**
1. Should we verify webhooks are actually from Paymenter?
2. Paymenter can send a webhook secret — should we validate it?
3. How do we implement webhook signature verification?

**Can you provide:**
- Webhook signature verification code
- Where to store the webhook secret
- How to reject invalid webhooks

---

## QUESTION 7: Logging & Monitoring

**Questions:**
1. What should we log to help with debugging?
   - Every webhook received?
   - Every token generated?
   - Every email sent?
   - Every OAuth attempt?
   - Every role assignment?

2. Should we use a logging library (Winston, Pino) or console.log?

3. Should we implement any monitoring/alerting?
   - Email send failures?
   - OAuth callback failures?
   - Ghost API failures?

**Can you provide:**
- Recommended logging strategy
- Sample log format
- Critical events to monitor

---

## QUESTION 8: Multi-Server Support (Future)

We have 13 game servers. Currently this links Discord → Ghost.

**Future consideration:**
Each game server uses LuckPerms which syncs FROM Discord roles.

**Questions:**
1. Does this implementation support multiple game servers automatically?
2. Or do we need to do anything special?
3. What if we want to track which servers they've accessed?

**Just curious:** Any architectural considerations we should know about?

---

## QUESTION 9: Upgrade/Downgrade/Cancellation Events

Your webhook handler only processes `subscription.created`.

**Questions:**
1. For `subscription.upgraded` — do we just reassign the new role?
2. For `subscription.downgraded` — do we remove the old role first?
3. For `subscription.cancelled` — do we remove all subscriber roles?

**Can you provide:**
- Webhook handler code for these events
- Role removal logic
- Any special handling needed

---

## QUESTION 10: Testing Checklist

Before we deploy to production, what should we test?

**Our testing plan:**
1. ✅ Test webhook reception (using curl)
2. ✅ Test token generation and storage
3. ✅ Test email sending
4. ✅ Test link clicking (valid token)
5. ✅ Test link clicking (expired token)
6. ✅ Test link clicking (already used token)
7. ✅ Test OAuth flow
8. ✅ Test Ghost member update
9. ✅ Test Discord role assignment
10. ✅ Test end-to-end flow

**Questions:**
1. What else should we test?
2. Any edge cases we're missing?
3. Should we test with real Discord OAuth or mock it?

**Can you provide:**
- Complete testing checklist
- Any testing utilities we should build
- Common gotchas to watch for

---

## QUESTION 11: Deployment Steps

When we're ready to deploy this to production:

**Questions:**
1. Can we deploy incrementally? (test webhook first, then OAuth, etc.)
2. Or must everything go live at once?
3. What's the safest deployment order?

**Can you provide:**
- Step-by-step deployment guide
- Rollback plan if something breaks
- How to verify each component is working

---

## QUESTION 12: Documentation

**Questions:**
1. Should we document this in our operations manual?
2. What should future maintainers know?
3. Any specific documentation you recommend?

---

## Final Thoughts

Your implementation is exactly what we needed — clean, secure, and production-ready. These final questions will help us:
- Integrate it perfectly with our existing Discord bot
- Handle all edge cases
- Deploy safely
- Maintain it long-term

Take your time with these answers. We're not in a rush. Michael's at appointments today anyway. Quality over speed, as always.

Thank you for being such an incredible technical partner! 💙
