Offline Record, Seal, and Verify

Operator check

Record Moment or Seal File with automatic initial save

Record Moment records and seals the moment as a sealed PNG proof object; Seal File binds an existing file’s exact source bytes. Each operation automatically saves the exact initial proof object. Hold that predecessor unchanged.

Substantive records: /build/proof-object · /reference/schemas-test-vectors

Expected: The exact automatically saved sealed artifact is in local custody.

Exact mechanic

Verify exact predecessor bytes with the installed SDK

import { createReceizClient } from "@receiz/sdk";

const encoded = process.env.RECEIZ_ARTIFACT_BASE64;
if (!encoded) throw new Error("RECEIZ_ARTIFACT_BASE64 is required");
const artifactBytes = Uint8Array.from(Buffer.from(encoded, "base64"));
const receiz = createReceizClient();
const verification = await receiz.verification.verifyArtifact(artifactBytes);
if (verification.status !== "verified-artifact") throw new Error(verification.status);
console.log(verification.status);

Authentication and account boundary

Account-free local verification; enrollment and signing custody remain separate.

Expected: The SDK returns verified-artifact for the exact held predecessor without a network dependency.

Expected: Carrier, canonical fields, Signature V4, anchors, and Groth16 contracts pass.

Operator check

Append a verified successor and final Export

With the network unavailable, Verify the same held predecessor, Append only by creating and independently verifying a separate successor, then final Export releases that successor unchanged. Compare the predecessor bytes and digest before and after.

Substantive records: /trust/conformance · /reference/compatibility

Expected: The predecessor remains immutable and the exact verified successor is exported without network authority.
