## Breaking Changes

**None.** This is a new feature that runs alongside existing channels.

- No config migration required
- Opt-in feature (disabled by default)

---

## Testing Checklist

### Unit Tests ✅
- [x] Auth flow with phone/SMS/2FA (mocked)
- [x] Phone number validation
- [x] Session verification
- [x] Message conversion (DM, group, reply)
- [x] Session key routing
- [x] Command extraction
- [x] Edge cases (empty messages, special chars, long text)

### Integration Tests ⏳
- [ ] End-to-end auth flow (requires real Telegram account)
- [ ] Message send/receive (requires real Telegram account)
- [ ] Multi-account setup (requires multiple accounts)
- [ ] Gateway daemon integration (needs openclaw built)

**Note:** Integration tests require real Telegram credentials and are best done by maintainers.

---

## Dependencies

### New Dependencies
- `telegram@^2.24.15` - GramJS library (MTProto client)

### Peer Dependencies (already in openclaw)
- Node.js 18+
- TypeScript 5+
- vitest (for tests)

---

## Documentation Quality

### Setup Guide (`docs/channels/telegram-gramjs.md`)
- 📋 Quick setup (4 steps)
- 📊 Feature comparison (GramJS vs Bot API)
- ⚙️ Configuration examples (single/multi-account)
- 🔐 Security best practices
- 🛠️ Troubleshooting (8 common issues)
- 📖 API reference (all config options)
- 💡 Real-world examples (personal/team/family setups)

### Code Documentation
- All public functions have JSDoc comments
- Type definitions for all interfaces
- Inline comments for complex logic
- Error messages are clear and actionable

---

## Known Limitations (Phase 1)

### Not Yet Implemented
- ⏳ Media support (photos, videos, files) - Phase 2
- ⏳ Voice messages - Phase 2
- ⏳ Stickers and GIFs - Phase 2
- ⏳ Reactions - Phase 2
- ⏳ Message editing/deletion - Phase 2
- ⏳ Channel messages - Phase 3
- ⏳ Secret chats - Phase 3
- ⏳ Mention detection in groups (placeholder exists)

### Workarounds
- Groups: `requireMention: true` is in config but not enforced (all messages processed)
- Media: Skipped for now (text-only)
- Channels: Explicitly filtered out

---

## Migration Path

### For New Users
1. Go to https://my.telegram.org/apps
2. Get `api_id` and `api_hash`
3. Run `openclaw setup telegram-gramjs`
4. Follow prompts (phone → SMS → 2FA)
5. Done!

### For Existing Bot API Users
Can run both simultaneously:
```json5
{
  channels: {
    telegram: {          // Existing Bot API
      enabled: true,
      botToken: "..."
    },
    telegramGramjs: {    // New user account
      enabled: true,
      apiId: 123456,
      apiHash: "..."
    }
  }
}
```

No conflicts - separate accounts, separate sessions.

---

## Security Considerations

### ✅ Implemented
- Session string encryption (via gateway encryption key)
- DM pairing (default policy)
- Allowlist support
- Group policy enforcement
- Security checks before queueing messages

### ⚠️ User Responsibilities
- Keep session strings private (like passwords)
- Use strong 2FA on Telegram account
- Regularly review active sessions
- Use `allowFrom` in sensitive contexts
- Don't share API credentials publicly

### 📝 Documented
- Security best practices section in docs
- Session management guide
- Credential handling instructions
- Compromise recovery steps

---

## Rate Limits

### Telegram Limits (Documented)
- ~20 messages/minute per chat
- ~40-50 messages/minute globally
- Flood wait errors trigger cooldown

### GramJS Handling
- Auto-retry on `FLOOD_WAIT` errors
- Exponential backoff
- Configurable `floodSleepThreshold`

### Documentation
- Rate limit table in docs
- Best practices section
- Comparison with Bot API limits

## Maintainer Notes

### Review Focus Areas
1. **Security:** Session string handling, encryption, allowlists
2. **Architecture:** Plugin structure, gateway integration, session routing
3. **Config Schema:** Backward compatibility, validation
4. **Error Handling:** User-facing messages, retry logic
5. **Documentation:** Clarity, completeness, examples

### Testing Recommendations
1. Test auth flow with real Telegram account
2. Test DM send/receive
3. Test group message handling
4. Test multi-account setup
5. Test session persistence across restarts
6. Test flood limit handling
7. Test error recovery

### Integration Points
- Gateway daemon (message polling)
- Config system (multi-account)
- Session storage (encryption)
- Logging (subsystem logger)
- Registry (channel discovery)

## Questions for Reviewers

1. **Session encryption:** Should we add option for separate encryption passphrase (vs using gateway key)?
2. **Mention detection:** Implement now or defer to Phase 2?
3. **Channel messages:** Support in Phase 1 or keep for Phase 3?
4. **Integration tests:** Add to CI or keep manual-only (requires Telegram credentials)?
