Enum UnresolvedReason 

pub enum UnresolvedReason {
    ManifestBlocked,
    Visibility,
    LanguageBoundary,
    MissingQuery,
    NoCandidate,
    Ambiguous,
    UnsupportedLanguageRule,
    IncompleteExtractorMetadata,
}

Why linkage could not bind a reference. The taxonomy is part of the resolution contract: consumers can split external-by-design from real resolution gaps instead of reading one opaque count.
