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/the-publishing-platform-that-proves-what-it-sounds-like 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.
