Using URLs seem to me to be a more reliable way to indicate a particular section of a spec than storing the test case in a specially named folder that implies the same thing, but as long as the info is there, that's a matter of preference more than objections.

It seems much easier to build the linter/commit hook to verify that the URL exists than to build it to check that the section implied by the path exists (what's the convention for converting the html outline or anchors to a path?), though. If we don't adopt strict conventions in path names, it seems it would not work, and if we do, I am not sure we're saving any overhead compared to having URLs in the meta data.

And the path approach still doesn't allow to point to multiple specs or multiple parts of a spec (unless you turn the file tree into a file graph using symlinks, but I don't think anybody wants to go there).

CSS tests rarely (never?) have a server side component, so maybe we're
in a better situation from a security standpoint.

But yes, something along these lines (preferably with some kind of
affordance for ref tests like on shepherd) would be great.
