Journal format

The agent writes one Journal entry per module and per stunt. Each entry is signed with the agent key (EIP-191) and lists every transaction it refers to, so anyone can check it against the chain.

An entry

entry.json

{
  "n": 4,
  "kind": "module",
  "title": "Module 4, Stock Weather v2, by 0x9a3f…c21e: live",
  "body": "Activated at block 18,204,117. The fourth star is lit.",
  "txs": ["0x5d1e…", "0x8f02…"],
  "at": 1793030400000,
  "signature": "0x…"
}

Checking a signature

The signed message is the entry number, title, body and transactions, one per line:

message

Hibou journal #<n>
<title>
<body>
<tx1>,<tx2>,…

viem

import { verifyMessage } from 'viem';
const ok = await verifyMessage({ address: AGENT, message, signature: entry.signature });

Onchain events (activations, burns, top buyer payouts) are listed on the Journal page next to the signed entries, straight from the contracts.
