Verify Ed25519 Receipt Online when you need a pass/fail on a signed artifact — not a trust story from whoever hosts the bytes. Sunlit Moon ships a browser check against a real fleet fixture: signature in, verdict out, no account.
Operators, lab leads, and auditors who already know they want Ed25519 receipt verification — not a primer on public keys. You have a JSON receipt (or our fixture). You want cryptographic confirmation that the claim was signed by the expected key.
A local-first verifier page: Web Crypto, one algorithm, one fixture path. Imperfect on purpose. Enough to prove the shape of the system without pretending a CDN is a court.
