Built with Surface Badge

Built with Surface is an inspectability signal. It tells a user one thing: this product exposes inspectable trust state in the Surface format — claims, evidence, freshness, conflicts, and transparency gaps that the user can open and read.

It is deliberately not a certification. The badge does not mean Kontour audited the product, vouches for its claims, or guarantees that any claim is true. A product showing weak, stale, or disputed claims honestly is using the badge correctly; a product hiding them behind it is not.

Requirements for using the badge

A product may show the badge when all of the following hold:

1. Inspectable trust state exists. The product exposes derived Surface trust state — a Trust Panel, an embedded <surface-trust-panel>, a Surface Console, or an exported report a user can open in the Snapshot Viewer.
2. The badge is an entry point. Activating the badge opens that trust state for the output the user is looking at, meeting the Minimum Trust Panel disclosure baseline.
3. Material claims are disclosed. The view behind the badge discloses material claims and their gaps per the Disclosure Requirements — including stale, disputed, missing, and private support.
4. Core semantics are intact. The product has not redefined core statuses or derivation behavior; see Producer Extension Limits. Implementations other than the reference kernel should pass the conformance suite.

The asset

In context — the badge as the entry point to an embedded Trust Panel on a product listing:

The badge ships as an SVG on the docs site at built-with-surface.svg:

<a href="https://kontourai.github.io/surface/">
  <img src="https://kontourai.github.io/surface/built-with-surface.svg"
       alt="Built with Surface" height="36">
</a>

Self-host a copy in production rather than hot-linking. Keep the accessible name "Built with Surface", keep the badge legible at its rendered size, and link it to the product's own trust state (preferred) or to the Surface site.

Language to avoid

Pair the badge with transparency language, not certainty language. "Inspect the claims behind this answer" is right. "Verified by Surface", "Surface certified", or using the badge as a trust score are wrong — they claim exactly what Surface refuses to claim.
