The `Link` header's `rel=\"last\"` is `page=81`,\nwhich is exactly `ceil(8040/100)`, confirming the server paginated internally\nat 100 per page — but the `href` for that last link **still carries\n`per_page=500`** in its query string. Following that link literally\n(`GET .../actions/runs?per_page=500&page=81`) gets you page 81 **of 100-item\npages**, not page 81 of 500-item pages — the Link header documents the true\npage count while misreporting the page size that produced it.
