RV and real-time properties
summary
A runtime verifier module now uses hybrid automata (timed constraints on nanoseconds) to validate the kernel’s real‑time behavior, applied to the deadline scheduler and finding real bugs after patches changed the code. Models observe tracepoints, infer state, and assert that a task never runs past its runtime; work exposes the need for a type field on the deadline entity and raises challenges for hierarchical servers and the new one per CPU per cgroup deployment.
