Anthropic's Check Files page is recorded as a provenance-tooling signal. It gives users a direct surface for checking whether files were made with Claude, which matters because generation provenance is shifting from metadata discussions into product UX.

The follow-up is whether those checks become interoperable, auditable, and available at publish or export boundaries.
