Paste a DCS Atlas receipt (or its id) and check it instantly — signature + hash-chain, independently, with no login and no central server.
Every action is signed with the agent's ed25519 key over canonical JSON. The public key is embedded in the receipt.
The receipt hash binds the signature to the payload. Change one byte and verification fails closed.
Verification runs against the receipt itself — no call to DCS, no trust in any server. Even works offline.
Verification is a public good — no account needed. This is the heart of the Earth Trust Layer.
