What makes it different
  • Independent verification separates proposing changes from deciding if available evidence is sufficient
  • Model-independent design works with any approved model or deterministic systems alone
  • Outcome-based billing charges only for validated fixes that pass verification
  • Governance by default with explicit approval, audit, and no shared credentials
  • Topology-aware impact analysis using System Graph to recommend validation plans
  • Only verification tool that reverses the fix to prove tests actually catch the bug
  • Deterministic verdict with no AI language model in decision logic
  • Tests on real hardware boards, not just laptops
  • Detects masking techniques that hide bugs while passing tests
  • Validated public benchmark showing 4 VERIFIED and 6 REJECTED on real open-source bugs
