+This proof demonstrates the memory safety of the TaskPrioritySet function. The
+initialization for the task to be set and `pxCurrentTCB` is quite similar
+(since the task handle may be NULL, and in that case `pxCurrentTCB` is used).
+Task lists are initialized with these tasks and nondet. filled with a few more
+items.
+
+This proof is a work-in-progress. Proof assumptions are described in
+the harness. The proof also assumes the following functions are
+memory safe and have no side effects relevant to the memory safety of
+this function:
+
+* vPortEnterCritical
+* vPortExitCritical
+* vPortGenerateSimulatedInterrupt
