CS-RV Implementation Guide

From Metaphor to Formalism: A Practical Translation

Purpose: This guide demonstrates the complete dessacralization of the constraint observation protocol, showing side-by-side comparison between metaphorical and formal implementations.

SIDE-BY-SIDE COMPARISON

Before: Metaphorical (Horus)

MIGRATION CHECKLIST

If migrating from metaphorical to agnostic implementation:

• Replace all class names (HorusObserver → ConstraintObserver)
• Replace all method names (witness_truth → register_state)
• Replace all field names (divine_ledger → state_ledger)
• Remove all metaphorical comments
• Replace string literals with neutral terms
• Run dessacralization test suite
• Verify all tests still pass
• Update documentation to remove metaphors
• Re-run adversarial tests
• Generate new audit trail

Automated tool:

python -m cs_rv.migrate --input old_code/ --output new_code/ --verify

SUMMARY

Key Principle:

If removing all metaphorical language changes system behavior, the metaphor was not metaphor—it was coupling.

The agnostic implementation:

• ✅ Zero semantic dependencies
• ✅ Passes total renaming test
• ✅ Continues under violation
• ✅ Conserves entropy
• ✅ Audit-transparent
• ✅ Production-ready

Status: Reference implementation complete and verified.
