Paste any Lattice certificate JSON. The check runs entirely in your browser— no upload, no server. Confirms BLAKE3 hash, ed25519 signature, ε bounds, and registry attestation.
All required fields present and well-typed — model, privacy, weights, signature, registry.
Weights hash is a valid 64-char BLAKE3 digest. The hash is not recomputed here — that requires the weights file.
Signature verifies against the registry's published public key for lattice-registry-2026.
For Hardened: ε ≤ 8.0 and δ ≤ 1e⁻⁵. Outside those bounds, the tier label is rejected.
