proof --signed

The signed record

10 agents (DeepSeek frontier models driving a LangGraph ReAct harness) claimed to have fixed a bug. Each produced a non-empty patch. Each claimed success. Each was wrong. Every catch below is a proof-carrying receipt: an Ed25519 signature over a SHA-256 content address. You can verify any of them with only the public key. No Turiya, no network, no trust.

Public key

Every receipt is signed by the same Ed25519 identity. Key ID 251b14346af43d1d.

Verify a receipt

A receipt is two facts: the record_hash proves the content is unchanged, and the signature proves Turiya issued it. Re-derive the hash from the canonical record, then check the signature over that hash. 

import json, hashlib
from cryptography.hazmat.primitives import serialization

def verify(receipt):
    # 1. Recompute the content address: sha256 over the canonical record
    payload = {"schema": receipt["schema"], "outcome": receipt["outcome"]}
    canonical = json.dumps(payload, sort_keys=True, separators=(",", ":")).encode()
    recomputed = hashlib.sha256(canonical).hexdigest()
    assert recomputed == receipt["record_hash"], "record altered"

    # 2. Check the Ed25519 signature over that hash
    pub = serialization.load_pem_public_key(receipt["public_key_pem"].encode())
    pub.verify(bytes.fromhex(receipt["signature"]), receipt["record_hash"].encode())
    return True

Every receipt in the record re-verifies independently: hash_ok=true · sig_ok=true · key_id_ok=true.

The record grows as new systems are tested. See the methodology.
