Sounds like you're saying I will be able to use CPONLY, as long as my flash remains intact, i.e. the FLDB is correct, regardless of whether RAM has lost power in the meantime?

That's even better, if so

thanks very much.

Yes, in the CPONLY mode the check is between the contents of the FLDB in FLash and the FLDB that is uploaded from the clupdate program. The results of these comparisons creates the CFLDB (by modifying the uploaded FLDB) which is then returned to the clupdate program.
