When creating a theme override...

[bjazmoore]

When creating a theme override if I need to add new or change values in the config.json -

I wondered: do I simply change the version in the original theme (seems unsafe), or create a copy with just the changes needed in the theme override folder? I tried this - with just the specific change I needed, but Publii does not merge the two versions together as evidence from the error message I got trying to access my previously accessible Pages.

My question is this: Will Publii merge the two complete files together if I have a copy in both the original theme and the override for the theme? If not then it is up to me to synchronize these when the theme is updated - right?

Yes. Create a copy of the entire file you want to modify, put the copy in your theme-override folder (create subfolders to recreate the path, if necessary), and make the mods in the theme-override version of the file.

Yes, or it picks/replaces the theme override version in favour of the original one.

Could you share the document tree of your site's input > themes folder (or a screenshot), and explain the changes ypu made to your config.json file?
