## Architecture Clarification

### Decision Document
- **File**: `docs/ARCHITECTURE_DECISION_EMONEY_VS_WTOKENS.md`
- **Status**: ✅ COMPLETE

### Key Decisions
1. ✅ eMoney vs W tokens are SEPARATE systems
2. ✅ W tokens CAN be used as vault collateral
3. ✅ Both systems can use ComplianceRegistry
4. ✅ Integration rules clearly defined

---

## Remaining Work (Non-Blocking)

### High Priority (Can Complete in Parallel)
1. Create additional test files (15+ files)
   - RateAccrual tests
   - Liquidation tests
   - VaultFactory tests
   - MintController tests
   - BurnController tests
   - ReserveOracle tests
   - TokenRegistry tests
   - TokenFactory tests
   - Integration tests
   - Fuzz tests

2. Complete additional integrations
   - INT-VLT-001: eMoney ComplianceRegistry integration (partially complete)
   - INT-VLT-002: eMoney token integration verification (testing needed)
   - INT-VLT-003: Oracle infrastructure integration (configuration needed)
   - INT-CROSS-001: W token as vault collateral (design complete, implementation pending)

3. Security audit
   - Review all contracts
   - Verify compliance rules
   - Check for vulnerabilities

4. Documentation
   - API documentation
   - Deployment guides
   - Runbooks

### Medium Priority (Post-MVP)
1. Monitoring infrastructure
2. Backup & recovery procedures
3. Incident response plans
4. Gas optimization

---

## Next Steps

### Immediate (This Week)
1. ✅ Run test suites to verify implementation
2. ✅ Fix any compilation errors
3. ✅ Test bridge integrations end-to-end
4. ✅ Verify deployment scripts work

### Short-term (Next 2 Weeks)
1. Create remaining test files
2. Complete additional integrations
3. Begin security review
4. Create deployment documentation

### Medium-term (Next Month)
1. Complete security audit
2. Set up monitoring infrastructure
3. Complete all documentation
4. Production deployment preparation
