Add BreadcrumbList to nested pages

If this is a change to your product

What must become true

Nested pages emit BreadcrumbList JSON-LD whose itemListElement has at least two ListItems, each with a position and a name, matching the visible trail.

Where it usually lives

Wherever the visible breadcrumb is rendered. Emit both from ONE component so the markup and the JSON-LD cannot drift apart — two sources for one trail is how they end up disagreeing.

The trap

Your own verification is the trap here, not the markup. A checker that fetches the first URL in sitemap.xml finds only CHILD SITEMAPS when that file is an index, so it reads nothing and reports nothing — and a site large enough for this step is exactly the site with an index. Follow the index one level before looking for a nested page.
