## The same check by hand

```sh
# 1. The receipt the WorkRegistry holds for the job (zero means none).
cast call 0xb6d0a187b050FA5Bb0B87033a203f37BECF4a775 "latest(bytes16)(bytes32)" 0x1c37ce1877b646c9893e3b9fc2f9b4fa --rpc-url https://ethereum-rpc.publicnode.com

# 2. The work record, hashed exactly as served.

# 3. The two lines above must print the same 32 bytes. Or, in one go:
[ "$(cast call 0xb6d0a187b050FA5Bb0B87033a203f37BECF4a775 "latest(bytes16)(bytes32)" 0x1c37ce1877b646c9893e3b9fc2f9b4fa --rpc-url https://ethereum-rpc.publicnode.com)" = "$(curl -s https://api.imd.fun/work-records/af40734a45db468cd77095fe0d294e4c21f16668cf567ee9a529894550513969.json | cast keccak)" ] && echo PROVEN || echo "NOT PROVEN"
