Why would this extremely simple test Rule NOT be getting triggered upon entity creation? It also fails to trigger for an entity update (if I change the Rule to trigger on a field update).
I think this was just another example of the FIbery backend lagging so far behind that it appeared broken. - Name formulas were also not updating.
But an hour later, everything appears to have caught up.
It is quite frustrating when there is no way to tell whether something is really broken, or everything is just lagging by… who knows how long?? 
There is no “spinner” to indicate that the backend is working to catch up and the current view is waiting on it.
