Graph-native platform for migrating legacy systems (Java 6/7, COBOL, .NET Framework) to modern stacks. Verifies behavioral equivalence per node with a six-gate evidence pipeline, runs old + new in parallel via a receipt-linked shadow bridge, emits cryptographically signed audit trails for regulators.

AI-assisted modernization of C#/.NET mission-planning software with behavioral-equivalence proof and continuous-ATO artifacts. U.S. Navy SBIR DON26BZ01-NV013 reference implementation. Runnable offline (no API keys); synthetic, unclassified surrogate; results preliminary, not government-validated.
