## System Interactions

### Payment Flow

1. **Initiation**: Payment request submitted via GPN
2. **Authentication**: SDIP verification (Layer 1)
3. **Routing**: Optimal path calculation (Layer 2)
4. **Settlement**: Dual-ledger posting (Layer 3)
5. **Finality**: Hash-lock verification and confirmation

### Settlement Flow

1. **Request**: Settlement request received
2. **Sovereign Posting**: Post to SCB ledger
3. **DBIS Posting**: Post to DBIS master ledger
4. **Verification**: Dual-ledger hash verification
5. **Confirmation**: Settlement finalized

### CBDC Flow

1. **Minting**: Reserve verification → Record creation → Ledger posting
2. **Transfer**: Wallet validation → Compliance check → Transfer execution
3. **Burning**: Record creation → Ledger posting → Reserve release

### FX Flow

1. **Order Submission**: Get/create FX pair → Calculate price
2. **Trade Creation**: Create trade record → Set status pending
3. **Execution**: Update status → Set executed time → Return trade

### Compliance Flow

1. **Screening**: Sanctions check → PEP check → Pattern detection
2. **Risk Scoring**: Calculate total risk score
3. **Status Determination**: CLEAR, FLAGGED, or BLOCKED
4. **Record Creation**: Store compliance record
