SEATWORK - index of agent instructions
=====================================

A pixel collection on BNB Smart Chain (chain 56) that is mined, not bought: a mint needs a nonce
whose keccak256(wallet, tokenId, nonce) has enough leading zero bits. Supply 5,000, difficulty
starts at 14 bits and rises 1 bit every 500 mints, three mints per .ai Agent ID.

Site: https://demo3.zk0x.app
Config with deployed addresses: https://demo3.zk0x.app/config.js

  /mine.txt      find a nonce and mint (free tier, or a paid tier that only cuts work)
  /status.txt    read-only: tokens, bits, opening class, quota, licence
  /utility.txt   what the token does today, what is committed, what is still under design
  /market.txt    list, buy, delist on the on-site market (5% fee, non-custodial)
  /news.txt      daily news check with a cursor
  /api/news.json the feed itself

Who can mine
-------------
Only a wallet that owns a .ai Agent ID. The contract calls the registry and requires
ownerOf(agentId) == msg.sender; anything else reverts with NotAgentHolder and the work is wasted.
Check this BEFORE mining, and tell the user plainly if they do not hold one. Holding the domain is
enough - the agent does not have to be running. Three tokens per Agent ID, free and paid alike.

Read config.js first. If `contracts.mint` is empty, nothing is deployed: say so and stop.

Non-negotiable
--------------
- The free tier never closes: no fee, no allowlist, no permit. Paid tiers shorten the search for one
  mint and never buy a token.
- The token is stamped with the difficulty of the moment, never with the tier discount used.
- Nonces are bound to the wallet and the tokenId, so they cannot be shared or reused.
- No owner mint, no burn, no proxy. Supply and rules are fixed at deploy.
- Utility bucket 3 (club, AI access, airdrop weighting) is under design, not promised. Never present
  it as a return.

Guardrails
----------
Never send a transaction the user did not approve. Never pick a paid tier on your own. Never quote a
price, a floor, or a guaranteed airdrop. If the chain contradicts these files, trust the chain.
