Distributed protocols are notoriously difficult to verify correctly. Proving safety typically requires inductive invariants that both imply the desired property and are preserved by every protocol transition; yet inferring such invariants remains a major bottleneck: existing approaches either restrict the protocol mode...

Sequence diagrams are widely used to model interactions among system components and external actors by explicitly describing how operations are executed over time. However, constructing sequence diagrams manually is tedious and time-consuming in practice, and their automated generation remains largely unresolved. In th...

CoHarden is proposed, a co-generation framework that uses the Lax signal as an in-loop convergence criterion that generates a test before any fix, then iteratively hardens the test and fix against surviving mutation patches until the generated test no longer admits Lax regressions.
