Key Features Demonstrated

1. Numeric Trust Levels (0-100)

The test suite validates the complete refactoring from categorical trust levels (high/medium/low) to numeric percentage-based trust (0-100), enabling fine-grained replication control.

2. Partial Replication via Dice-Throw

Statistical validation proves the cryptographic random selection mechanism works correctly across all trust levels, with proper distribution over 1000 iterations.

3. Group Tag Ownership

Comprehensive testing of the DNS-like registration system with single and multisig ownership schemes, including transfer capabilities.

4. URL-Safe Validation

RFC 3986 compliance testing ensures group tag names work correctly in URL contexts and prevents injection attacks.

5. Cryptographic Operations

All events are properly signed using p256k.Signer which implements the signer.I interface with BIP-340 Schnorr signatures.

Adding New Tests

1. Follow existing test structure
2. Use createTestKeypair() helper for key generation
3. Include both positive and negative test cases
4. Add descriptive error messages
5. Use subtests for related scenarios

Conclusion

This test suite provides comprehensive coverage of the distributed directory consensus protocol, validating all message types, cryptographic operations, and validation rules. The tests demonstrate that the numeric trust levels, partial replication mechanism, and group tag ownership systems work correctly across all edge cases.

All tests passing ✅ - Protocol implementation is stable and ready for deployment.
