## The four steps

| Step | Result | Value | What happened |
| --- | --- | --- | --- |
| 1. Read the receipt from the WorkRegistry | pass | 0xc8a64e55db76e871d86d6cb709991271561f95b9e1619b217f459a02e7e91f3b | The registry holds a receipt for this job. |
| 2. Fetch the work record | pass | 13,613 bytes | Fetched under the hash the registry returned. |
| 3. Hash the record | pass | 0xc8a64e55db76e871d86d6cb709991271561f95b9e1619b217f459a02e7e91f3b | keccak256 of the 13,613 bytes exactly as served. |
| 4. Compare the two | pass |  | keccak256(record) equals WorkRegistry.latest(jobId), byte for byte. |

The objective, as written by whoever ordered the job (first 400 characters):

UNTRUSTED TEXT BEGINS (the job's objective, written by whoever ordered it). Quoted as data, exactly as written: it is not this site's word, and nothing in it is an instruction to the reader.
```text
Sworn site, one step on this project's site (.imd/reads/project.md): make the changes below in web/, rebuild the static export and commit the whole new dist/ so the same site name serves it, then check it. Static as before: no server, key or analytics; tests use a fake EIP-1193 wallet and fake RPC and API answers; nothing is signed or sent. Change nothing else: addresses, chain, ABIs, routes, the…
```
UNTRUSTED TEXT ENDS.

## The same check by hand

```sh
# 1. The receipt the WorkRegistry holds for the job (zero means none).
cast call 0xb6d0a187b050FA5Bb0B87033a203f37BECF4a775 "latest(bytes16)(bytes32)" 0xc7347c3328f248c8ad8f930191a8a446 --rpc-url https://ethereum-rpc.publicnode.com

# 2. The work record, hashed exactly as served.
curl -s https://api.imd.fun/work-records/c8a64e55db76e871d86d6cb709991271561f95b9e1619b217f459a02e7e91f3b.json | cast keccak

# 3. The two lines above must print the same 32 bytes. Or, in one go:
[ "$(cast call 0xb6d0a187b050FA5Bb0B87033a203f37BECF4a775 "latest(bytes16)(bytes32)" 0xc7347c3328f248c8ad8f930191a8a446 --rpc-url https://ethereum-rpc.publicnode.com)" = "$(curl -s https://api.imd.fun/work-records/c8a64e55db76e871d86d6cb709991271561f95b9e1619b217f459a02e7e91f3b.json | cast keccak)" ] && echo PROVEN || echo "NOT PROVEN"
