## Governance Compliance

This scaffold follows the **MIRROR KITTY Phase Mirror Governance** model:

1. ✅ **Be Impeccable with Your Word**
   - All outputs documented
   - Manifest hash provides cryptographic integrity
   - GenesisConfig signed (pending)

2. ✅ **Don't Take Anything Personally**
   - Agent-agnostic design
   - Contract templates define interfaces, not implementations
   - Verification independent of implementation

3. ✅ **Don't Make Assumptions**
   - All decisions documented in ADR-100
   - Explicit success criteria
   - Clear handoff artifacts

4. ✅ **Always Do Your Best**
   - Comprehensive scaffolding
   - Multiple verification layers
   - Ready for production implementation

## Risks and Mitigations

### Risk: Template Modifications
**Impact:** Manifest hash mismatch  
**Mitigation:** CI/CD workflow verifies hash on every commit

### Risk: Missing Dependencies
**Impact:** Implementation agents blocked  
**Mitigation:** All dependencies documented in contract templates

### Risk: Specification Drift
**Impact:** Implementations diverge from spec  
**Mitigation:** Master XML specification is source of truth

### Risk: Incomplete Proofs
**Impact:** Formal verification incomplete  
**Mitigation:** Lean 4 template marks all proof obligations with `sorry`
