Every check on this page runs in your browser, against publicly cached endpoints. We don't push the result — your browser fetches it fresh. If this page says green, the worker is up right now, not "as of the last time we manually updated a JSON file."
The provenance check actually recomputes the SHA-256 of the most recent record's payload using crypto.subtle.digest, then compares it to the hash the Mac Mini stamped at alert time. If a single byte of the payload changed, you'd see red here — there is nothing for us to fake.
The page auto-refreshes every 60 seconds while open. To verify a specific record yourself, paste its ID into /verify.html.
