# Example Proposal: Minor Feature Addition

**Note**: This is an EXAMPLE proposal for reference. It demonstrates a proposal for a non-breaking feature addition that requires formal proposal due to cross-system impact.

# Tier-1 Canonical System Change Proposal

**Proposal ID**: PROPOSAL-2025-0201-001
**Date**: 2025-02-01
**Proposer**: DBIS Development Team
**System Affected**: DBIS
**Type**: Functional

---

## 1. Executive Summary

This proposal adds a new API endpoint to DBIS for retrieving enhanced account information. While non-breaking, this change requires formal proposal due to potential cross-system integration by ICCC and SMOM/SMOA systems.

---

## 2. Rationale and Justification

### Problem Statement
ICCC and SMOM/SMOA systems require enhanced account information that is currently not available through existing DBIS APIs. This limits cross-system integration capabilities.

### Proposed Solution
Add new `/api/v1/accounts/{id}/enhanced` endpoint that returns extended account metadata including compliance status, risk tier, and jurisdictional information.

### Alignment with Constitutional Principles
- Maintains DBIS responsibility for account information (Section II.A)
- Supports cross-system coordination (SMOM/SMOA responsibility, Section II.C)
- No impact on mutual recognition framework
- Preserves system boundaries

---

## 3. Impact Assessment

### Affected Systems
- [x] DBIS (implementation)
- [x] ICCC (potential integration)

## 6. Risk Assessment

### Technical Risks
- **Low Risk**: Addition only, no modification to existing functionality
- **Mitigation**: Comprehensive testing, backward compatibility maintained

### Governance Risks
- **Low Risk**: No impact on constitutional principles
- **Mitigation**: Maintains system boundaries, supports cross-system coordination

---

## 7. Testing and Validation

### Testing Strategy
- Unit tests for new endpoint
- Integration tests with existing systems
- API documentation examples

### Validation Criteria
- Endpoint returns expected data format
- No impact on existing endpoints
- Documentation complete
- Integration examples provided

### Rollback Plan
- Simple endpoint removal if issues arise
- No impact on existing functionality

---

## 8. Documentation Updates

### Required Documentation Changes
- [x] API documentation: Add endpoint documentation
- [x] Integration guide: Add integration examples
- [ ] CANONICAL_CONSTITUTION.md: No changes required
- [ ] NOTICE.md files: No changes required

---

## 9. Constitutional Compliance Checklist

- [x] Does not unilaterally supersede another canonical system
- [x] Maintains mutual recognition framework
- [x] Preserves continuity principles
- [x] Respects Tier-1 system boundaries
- [x] Aligns with Section IV governance principles
- [x] Documentation is inspection-safe

## 10. Approval and Recognition Log

| System | Status | Recognized By | Date | Notes |
|--------|--------|---------------|------|-------|
| DBIS | Pending | - | - | - |
| ICCC | Pending | - | - | - |
| SMOM/SMOA | Pending | - | - | - |

**Final Status**: Under Review
**Constitutional Amendment Required**: No
**Version Increment**: N/A
