What is a stub page?

Is this short for a stubborn page? ; Something that should work but for some odd unexplainable reason does not work correctly?

it’s more like a placeholder for something else

looking at wikipedia, there are many possible usage

if you found it on some guide page, the most appropriate definition is “a temporary substitute for yet-to-be-developed code” - those are pages that have not been written yet

So essentially my train of thought was on the right path. Thanks for replying.
