Verifier Playground

Sign a fresh challenge with an agent's signing key, then verify the signature against the agent's agent.signing-pubkey record. Toggle Tamper to mutate one byte and watch the verifier reject it live. Local verify is Ed25519-equivalent to the on-chain check.

Tamper — flip byteWhen on, message byte at that index is XOR'd with 0x01 before verify.
