<!-- coverlet.MTP is a native Microsoft.Testing.Platform extension, not a build-time-only tool
like the VSTest coverlet.collector was: its self-registration codegen needs the package on
this project's own compile-time closure, so IncludeAssets must not exclude "compile" (the
collector's restricted list omitted it, which is fine for a VSTest data collector but
breaks a compiled-against library). PrivateAssets is unrelated to that and stays unset,
since it only controls exposure to downstream consumers, which this test project has none
of. -->
