How/when is the OPF created? When a book is added to Calibre? Well maybe that doesn't matter. But if there is no OPF, will CP not run or always fail?

If I have a book with an OPF but the OPF does not have a Goodreads identifier, how do I get that line in the OPF? Is that a function of downloading metadata? It does not appear to be, since the metadata download does not grab from Goodreads either.
The existence or not of the OPF file in the library directories has absolutely nothing to do with how the plugin works. The Count Pages plugin, and all other plugins, use the calibre API. That gets the data from the database. The OPF files are a backup of the database. I asked to see the OPF file as an easy way to find out if you had the appropriate identifiers set.
