Governance Compliance
This scaffold follows the MIRROR KITTY Phase Mirror Governance model:
β Be Impeccable with Your Word
- All outputs documented
- Manifest hash provides cryptographic integrity
- GenesisConfig signed (pending)
β Don't Take Anything Personally
- Agent-agnostic design
- Contract templates define interfaces, not implementations
- Verification independent of implementation
β Don't Make Assumptions
- All decisions documented in ADR-100
- Explicit success criteria
- Clear handoff artifacts
β 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
