This tool checks signed projections and the development-scan receipt from the Cycle 2 run. Drop either file below and your own browser recomputes the digest and checks the Ed25519 signature against the published projection key - locally, in this tab. For a receipt, the signature check covers the separately committed summary; it does not verify a signature over the receipt itself. The tab also pins the recomputed digest to the committed receipt hash; when a receipt does not match the committed signed summary, or cannot be parsed, the signature line is skipped. If a check fails, it says exactly which check failed and why. A valid signature does not recompute the acceptance verdict or prove independent key provenance.
