SchedCheck performs partial-order exploration over dependence-equivalence classes of schedules on the Scratch VM to detect and localize schedule-sensitive behaviors, reporting 17-21% of real concurrent projects affected.
A certificate-carrying rewriting system for Scratch-like languages uses a trusted checker to verify optimizer rewrites by recomputing preservation conditions, with a Lean-mechanized cooperative-frame refinement theorem covering multiple state families and 94.3% acceptance on 300 projects.
