As each verifier becomes real, the circle becomes a checkmark. The page verifies only what's actually supported — honest by design.

Every governed operation seals its state into a portable receipt — an H33-74 commitment signed with post-quantum ML-DSA-65. It carries its own public key.

Exhibit 11
Verify it yourself. Offline.
The verifier runs entirely in your browser as WebAssembly — the same engine used for genuine receipts. No server is contacted.
Real ML-DSA-65 (FIPS 204) + H33-74 (SHAKE256), compiled to WebAssembly.
Exhibit 12
What happens if H33 disappears?
The verifier is local and the receipt is portable. Verification depends on nothing but the receipt's own bytes.

The verifier makes zero network, DNS, or time-of-day calls — so none of these can change the result.
