Description

MC:

Maintain a guarantee that counterexamples to safety are minimal in length, even when running on multiple threads. (Once a thread has a counterexample, it should be possible to check that other threads cannot possibly produce a shorter one before reporting it.)

Research direction

The issue identifies MC and its multi-threaded safety counterexample reporting, but names no files or tests. Begin by locating the parallel counterexample path, then determine how to verify that no other thread can produce a shorter counterexample; done means safety counterexamples remain minimal when multiple threads run.
