Function warn_if_pagination_truncated 

pub fn warn_if_pagination_truncated(
    provider: &str,
    ecosystem: &str,
    noun: &str,
    name: &str,
    page: u32,
    page_len: usize,
    max_pages: u32,
)

Logs a warning when pagination for name stops at max_pages while provider still had more pages available (page_has_more(page_len)).

Without this, hitting the safety ceiling on a pathological repo/project is indistinguishable in logs from “there is genuinely no matching version” — this makes truncation diagnosable. provider names the upstream API ("GitHub", "GitLab"); ecosystem names the caller ecosystem (e.g. "Swift", "GitHub Actions", "GitLab CI"); noun names what is being paginated ("tags", "releases") in the warning text — a caller pagintating a non-tags endpoint (e.g. GitLab CI’s /releases) must not have its warning hardcode “tags” pagination.
