The hash above is SHA-256 over this receipt's canonical JSON: keys sorted, no spaces, UTF-8. Re-hash it in one line; you should get 4f0459f97e7f…21118c48:

curl -s https://verano-square.fly.dev/api/turf/receipts/b995046-k8-claim | jq -cjS .receipt.document | sha256sum

That rebuilds the canonical form from the JSON with jq -S (jq 1.6+). Or hash the exact stored bytes: curl -s https://verano-square.fly.dev/api/turf/receipts/b995046-k8-claim/canonical | sha256sum

  1. Chain. The document includes prev_hash. It must equal the previous receipt's hash (b995046-k7-defend), so no earlier receipt can change without breaking every one after it.
  2. Source. Every value under facts is copied from grift.world's public feed, same keys, same values. While the city still lists it (about the last 14 nights; the last 300 burns), compare:
    curl -s https://www.grift.world/api/crews | jq '.chest.burns[]|select(.id=="crew:d995046:k8:claim")'
