I honestly don't recall if there are changes to the default Lucid files. It's been some time.

There is nothing in the upgrade_modules.log file since an update to a module in Feb 2023, even after another attempt to upgrade the Lucid module today. However, the sys_modules.log file does show a very generic message:

tail sys_modules.log
