Also, why does type-check use the vitest tsconfig? I'd expect it to use the app tsconfig.

Because the vitest tsconfig covers both the app modules and the test spec modules, therefore more comprehensive than the app tsconfig.

But never mind, after #274 we'll be using vue-tsc --build --force for type-checking. That would be more intuitive.

Got it, thanks @sodatea. I did try that out and ran into an issue, which I've flagged on the PR. Still, good to understand the current setup.

To throw in a tsconfig that threw me off more than others: the cypress one that's under cypress/e2e. I generated a scaffold and copied over the tsconfig files in the root dir to my actual project, but missed that one until just now. I only knew it existed because I was browsing around templates.
