Radly is a bipartite AST and blast radius engine for ML & scientific code. Standard tests only check if code runs—not if your research claims still hold. Radly maps code symbols directly to paper equations, sections, and benchmark tables. When you modify code, Radly computes the exact blast radius: pinpointing invalidated equations, impacted claims, and risk levels before you merge. Features: • Code-to-paper AST graph • Risk scoring & impacted claim detector • Exportable audit reports
