How verification works
- Pinned issuer key. Ed25519 public key hard-coded in this bundle — signatures cannot be forged even if the API is breached.
- Local-only proof. No wallet permission, no private key access. Your browser does the math.
- Sybil-checked score. Diversity, freshness and graph-cluster scans run server-side before any score is signed.
- Tamper badge. Any mutation of payload bytes flips the verdict to Failed instantly.
