One final point on smog, while extremely rare it is possible to have smog from entirely natural sources.
There is Smog and then there is Smog.
A 1890-ish London Pea Soup Fog (the original "Smog") was chemically different from a 1960-ish Los Angeles Smog and both are chemically different from an Alaskan Wildfire feeding a temperature inversion (aka "natural Smog")
A spectroscopic detector would be able to distinguish between types of Smog and detect the "fingerprint" of internal combustion engines. (much as "Smog Check" stations can isolate several different pollutants and check them against established limits -- if they're actually checking and not asking VW's engine computers.)
IOW, not all Smog is created equal and it should be trivial to distinguish the cause.

If the Temple Loyalists haven't stopped the violations of the Proscriptions, then the OBS will have to do it for them. [/sarcasm]
The OBS is a computer, and it can't distinguish between "temple loyalists" and "heretics" from orbit. It can, at best, detect forbidden levels of technology beyond what the Inquisition should allow; IF the OBS can act autonomously, it is going to assume the Inquisition has failed to enforce the Proscriptions and that there are no "Temple Loyalists" left before it acts.
