Expected log hash

90099e0300c6e23b62e79318296ebab91bff130379d248ada57f044f77e72ccd The log entry's spec.data.hash.value must equal this value: the SHA-256 of the Merkle root string above. Recompute it yourself from the root to confirm.

Canonical record

{"dataset_version":"v1789796056710","kind":"published-quote","locale":"pt","page":"theme:rappi/billing/pt","quote":"Cobrança indevida de R$ 85 após cancelamento e devolução do pedido","rating":1,"review_date":"2026-09-16","source":"Reclame Aqui","source_url":"https://www.reclameaqui.com.br/rappi/fui-cobrado-indevidamente-r-85-por-pedido-cancelado-e-devolvido_LGXsSCVS2RfQ-1bD/","v":1}

Verify in the public log

1. Open the Rekor entry (pre-filled with this proof's log index).
2. In the entry, compare spec.data.hash.value with the "Expected log hash" above: it is the SHA-256 of the Merkle root string (2f068f3de56b…), which ties this proof's root to the log entry.
3. Decode spec.signature.publicKey.content from base64: it must equal Citatio's published key at /.well-known/citatio-signing.json.
4. The entry's integratedTime is the independent timestamp: the root, and with it this quote, existed no later than that moment.
5. Locally, without any Citatio infrastructure: SHA-256 the canonical record (must equal the record hash), verify the Ed25519 signature against the public key, and fold the hash through the Merkle path (sorted-pair SHA-256) to reach the anchored root.
