Function declaration_source 

pub fn declaration_source(resolved: &Resolved) -> Option<DoctorCheck>

The trust-root check: which copy of the declaration is obeyed, and every line of the working tree’s copy this runtime ignores because the trunk’s copy does not say it (super::root). None when there is no declaration to judge.
