The verification badge
Every verified site has a public page at /verify/<token> showing the hostname, the live score, the pillar results and the last-verified date. The badge image embeds anywhere and always reflects the current state.
Embedding
Copy the snippet from your site page in the app:
<a href="https://web.sichta.gigliotti.software/verify/YOUR-TOKEN">
<img src="https://web.sichta.gigliotti.software/verify/YOUR-TOKEN.svg"
alt="Sichta verified" width="200" height="44" />
</a>
Lapsing
If verification stops — the subscription ends, or the daily checks start failing and stay failing — the badge and the page say so, with the date. A badge that cannot lapse proves nothing; this one lapses. That's the point.
