package main

// A failed unit is never silent (novox/hq issue 315, "how it is checked"): a module's failed unit raises
// the module's condition on the second statement, naming the unit; the machine's own failed units raise
// one finding for the machine, listing them, cleared when none is listed; an engine that says nothing of
// its units raises and clears nothing; and the gate never holds a send on the machine's own.
