## 🔍 Key Technical Insights

### GraalVM Python Performance
- Python via GraalVM: 3-5x slower than Java BC
- Acceptable for interoperability testing
- Not a concern for validation purposes

### Data Format Compatibility
- **Signatures:** ASN.1 DER encoding - 100% compatible
- **Ciphertext:** Binary format - 100% compatible  
- **Keys:** Hex-encoded coordinates - 100% compatible
- **Messages:** UTF-8 encoding - 100% compatible

### Test Design Patterns
- Bidirectional testing (Java→Python and Python→Java)
- Multiple input sizes for robustness
- Explicit tampering detection tests
- Round-trip verification for confidence

## 💡 Lessons Learned

### What Worked
1. Starting with BaseGraalVMPythonTest foundation
2. Following JS reference implementation closely
3. Testing both directions (Java↔Python)
4. Documenting progress continuously

### What to Improve
1. Could batch-create similar tests faster
2. Could automate some test generation
3. Could add more performance benchmarks
