+\****************************************************************************************
+\* Monitor tests
+\* Each monitor test is a tuple of 
+\* (Init, TxRes, Mon) which should be produced / filled 
+\* by fetcher / verifier, where:
+\* - Init is any initial predicate
+\* - TxRes is a conjunction of any of Tx and Res predicates
+\* - Mon is any monitor predicate; produced from monitor specs
+\*
+\* A monitor test is validated via running
+\* apalache-mc check --length=1 --init=Init --next=TxRes --inv=Mon timelock_mon_tests.tla
