Enterprise migrations can copy every row and still break the business. Critical renewal rules, grace periods, and balance semantics often live in application logic and transaction history—not just database schemas.

Coharyn Migration Autopilot is a DNA-first, evidence-governed prototype built with Meta Muse Spark 1.3.

It connects read-only to synthetic PostgreSQL systems, discovers their System DNA, and uses AI to investigate hidden business behaviour. Evidence-backed hypotheses become Behavioural DNA, with deterministic verification, explicit uncertainty labels, and human approval before testing.

Our demonstration shows a legacy system passing 8/8 behaviour tests, a deliberately broken migrated system passing only 5/8, and an authorized correction restoring 8/8—with the source database unchanged.

We also explored recursive cross-system intelligence. Although the experimental engine discovered genuine relationships and hidden rules, it failed its preregistered uncertainty-reporting gate. That NO-GO result is disclosed, and the experimental engine is excluded from the approved product.

The wider Coharyn vision predates the hackathon. This isolated implementation was developed during the event.

The result is a reproducible synthetic prototype demonstrating how AI-assisted discovery and governed testing can help businesses preserve critical behaviour during migration—not a claim of production validation.
