{
"instructions": "Random integers derived from the drand quicknet public randomness beacon, a server secret, a per-request nonce, and, when a public KiwiSDR receiver delivers a clean sample, a hash of live HF atmospheric noise. Every value carries the drand round, the beacon signature, a commitment hash binding all inputs to the value, and a URL where the round can be re-verified against a beacon no single party controls. When drand is unreachable the tools return an error rather than a locally generated number. What is provable: the value derives from a specific signed beacon round, and is unpredictable to anyone who does not hold the server secret. What is attested but not provable: the physical noise. Each response says in provenance.physical whether live noise went into that draw, from which receiver, at what signal level, and with what sample hash; when no receiver was available the draw proceeds from the beacon and nonce alone and says so. Suitable for games, draws, sampling, and any use needing an auditable trail. Not a substitute for a CSPRNG when generating keys or secrets.",
