Take FlashWithMutex without the CMP abstraction - #125
Merged
Conversation
Upstream tlaplus/Examples#226 moves the Murphi model's CMP Other-node abstraction into a separate FlashWithMutexCMP.tla. That abstraction exists so that model checking one node count stands for all of them; TLAPS proves the protocol for every constant value, so its ABS_* rules, the Env_o conjunct in every UNCHANGED list, and the Other-widened NodeU were only ever noise in a proof target -- and noise interleaved with the protocol's own actions. The benchmark tracks the protocol alone. All 17 theorem statements are unchanged, so the targets are the same; the regenerated model drops 268 lines and nine Defs files lose the ABS_* actions and the fairness conjuncts that existed to keep them live.
