8. Known Limitations

Score Proofs

1. HSM integration requires compatible hardware
2. Post-quantum algorithms not yet available
3. Rekor integration requires network connectivity

Reachability

1. C/C++ support is limited (best-effort)
2. Reflection may cause under-reporting
3. Large codebases (>1M nodes) may need depth limiting

Unknowns

1. Historical data not auto-migrated
2. Pattern matching is case-sensitive
3. Bulk operations limited to 1000 items

---

9. Future Roadmap

v2.6.0 (Planned)

• Post-quantum cryptography support
• Enhanced dynamic dispatch handling
• Reachability caching improvements
• UI dashboard for unknowns

v2.7.0 (Planned)

• Runtime reachability integration
• Proof archival service
• Cross-tenant unknown sharing
• Advanced call graph visualizations
