## The four steps

| Step | Result | Value | What happened |
| --- | --- | --- | --- |
| 1. Read the receipt from the WorkRegistry | pass | 0xb4d9376eeceed01d83574be1c34c6e69804506fecc3e33ba7812f17c6d0b2c41 | The registry holds a receipt for this job. |

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
Build the website for NightStakes. A one-page site for NightStakes: the promise (Instant, high-stakes micro-duels where skill wins the pot and every round fuels the Night Shift economy.), who it is for (Crypto-native degens and competitive mobile gamers aged 18-35 who already hold $SHIFT/$IMD or Night Shift NFTs and chase adrenaline-fueled, on-chain PvP wagering.), the products with prices, a buy…
```
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)" 0xd1a9542b0aef4896952ec70be276d717 --rpc-url https://ethereum-rpc.publicnode.com

# 2. The work record, hashed exactly as served.
curl -s https://api.imd.fun/work-records/b4d9376eeceed01d83574be1c34c6e69804506fecc3e33ba7812f17c6d0b2c41.json | cast keccak

# 3. The two lines above must print the same 32 bytes. Or, in one go:
[ "$(cast call 0xb6d0a187b050FA5Bb0B87033a203f37BECF4a775 "latest(bytes16)(bytes32)" 0xd1a9542b0aef4896952ec70be276d717 --rpc-url https://ethereum-rpc.publicnode.com)" = "$(curl -s https://api.imd.fun/work-records/b4d9376eeceed01d83574be1c34c6e69804506fecc3e33ba7812f17c6d0b2c41.json | cast keccak)" ] && echo PROVEN || echo "NOT PROVEN"
