"""What a published wheel has to do, checked where nothing else is installed.

`cibuildwheel` runs this against each built wheel in a clean environment, which is the
one property that matters here: it is the only place in the whole pipeline that looks
like a user's machine rather than a developer's. The error path of the parser binding
once imported `pyllhttp` — archived, not a dependency, present on both machines this was
written on and on no other — and every check we had passed anyway, because every check
we had parsed *valid* traffic.

So: a good exchange, a bad one, and the exception that names it.
