What this page exposes

Verification runs on the server. The browser only sees the public summary in the sidebar and the step-by-step ok/fail result above — never the certificate's raw signature, the tenant's raw public key, the ToneHash salt, the per-axis tonal scores, or the compact fingerprint string. Those stay on the signing host.

The public JSON at /tonehash/cert/verbatick-from-a-spoken-thought-to-a-working-product mirrors the same surface. To independently audit a certificate's raw signed payload you must request an authenticated cert-bundle export from the operator — how to request access.
