Team Idea

ChangeTwin is a Bob-native developer workflow that rehearses code changes before they are merged. It runs the same realistic scenarios against the old and new versions of a codebase, detects hidden behavioral regressions, explains what changed, and generates regression tests for approved findings.

ChangeTwin is a dynamic differential execution engine that catches silent AI refactoring bugs. By running real-world edge cases through original and refactored code simultaneously, it generates an immutable Diff Passport to ensure production stability.
