1. **Payment Gateway** - Intents, captures, refunds
2. **Wallet Accounts** - Stored value with P2P transfers
3. **Card Issuing** - Virtual/physical cards with controls
4. **Mobile Money** - Provider abstraction for cash-in/out/transfers

#### Operations & Deployment ✅

## Acceptance Criteria Met

✅ Any capability can be disabled at runtime  
✅ Requests blocked consistently at gateway and service layers  
✅ Every decision and toggle change is auditable  
✅ Ops console allows toggling capabilities  
✅ All money movement posts to ledger via standardized API  
✅ Limits enforced centrally  
✅ Fees calculated dynamically  
✅ Each capability pack toggles independently  
✅ Provider connectors are swappable  
✅ End-to-end flows work with capability checks  

## Conclusion

The SolaceNet platform is **production-ready** for Phases 1-3. The foundation is solid, extensible, and follows best practices. The system can now:

- Toggle capabilities at runtime without redeployment
- Enforce policies across multiple layers
- Provide complete audit trails
- Support multiple capability packs
- Scale horizontally with the Go gateway

**Status: ✅ READY FOR DEPLOYMENT**
