Verify independently

Three steps, no AirIndex servers required after step 1.

1. Fetch the full proof (JSON)
curl /api/provenance/record?table=AixIdentifier&id=aix%3Ahp%3AQNPPAST1
2. Recompute the leaf hash

Extract identity columns (id, assetType, internalTable, internalId, mintedAt) from the AixIdentifier row for aix:hp:QNPPAST1. Canonicalize as JSON: sorted keys, no whitespace, ISO 8601 dates, explicit nulls. Prefix with AixIdentifier:. SHA-256 → hex. Must equal leaf.hash in the JSON.

3. Verify the anchor proof

Base64-decode anchor.tsa.signature_base64 and run:

openssl ts -verify -in tsr.der -CAfile <DigiCert TSA root cert>

Or, for the trustless path (once Bitcoin has confirmed):

ots verify proof.ots
