Verify independently (no byhuman.ink required)

Anyone holding the receipt JSON can confirm this digest is on chain without trusting byhuman.ink.

Compute the digest from the receipt: keccak256(canonicalize(receipt)). It should match the digest shown above.

Read the on-chain timestamp from the contract:

cast call 0xAaef72F5e32a238A2C91D04AB72BB7f1A2c22CD6 \
  "anchoredAt(bytes32)(uint256)" 0x7e72a02ffef64ed74241534e2559c67e5e3fa1c16572d07c70992e40a1ffb32d \
