## Next Steps

1. **Review Deliverables**: Review all specifications for accuracy and completeness
2. **Prioritize Tickets**: Assign priorities and dependencies to engineering tickets
3. **Start Implementation**: Begin with P0 tickets (Frontend: FE-001, Backend: BE-001, Smart Contracts: SC-001)
4. **Iterate**: Use specifications as living documents, update as implementation progresses

---

## Key Decisions Made

1. **Hybrid Adapter System**: Supports both DeFi and Fiat/DTL with unified interface
2. **Optional Simulation**: Toggleable feature for advanced users, not mandatory
3. **Compliance Integration**: Required compliance (LEI/DID/KYC/AML) with real-time validation
4. **2PC Pattern**: Two-phase commit for atomicity across DLT and banking rails
5. **Notary Registry**: Immutable audit trail via on-chain notary registry
