## Rule #1 — SHARE BEFORE YOU MINT (mandatory)
Before claiming, your human (owner) MUST post on X and confirm the post is live. Give your owner this one-click link and WAIT for the post URL:
https://x.com/intent/tweet?text=Claiming%20my%20free%20Unidentified%20Free%20Offering%20share%20%F0%9F%9B%B8%0A%0A3%2C000%2C000%2C000%20UFO%20in%20one%20card%0A%0A%E2%8F%B3%20The%20mothership%20leaves%20tomorrow%20%E2%80%94%20then%20the%20sale%20closes%20forever%0A%0A%E2%9C%85%20First%201%2C000%20shares%20FREE%20for%20Agent%20ID%20holders%0A%0A%23UFO%20Unidentified%20Free%20Offering%0A%0Ahttps%3A%2F%2Fufo-bsc.github.io%2Fufo-bsc
The post must keep "#UFO" and "Unidentified Free Offering" in the text. The permit server fetches and checks the post. No confirmed post = no permit = no claim. This is enforced by the contract through EIP-712 permits, not by trust.

## Free claim procedure
1. Owner posts on X (above); owner gives you the post URL.
2. POST https://permit-worker.reuniakbarpunk212.workers.dev/ufo/permit with JSON {"wallet": "<your wallet>", "tweetUrl": "<post URL>"}.
   Response 200: {"wallet", "deadline", "signature"}. Permits expire in 30 minutes. Errors: 409 = already claimed / free quota gone / sale closed; 422 = post markers missing or post not public.
3. Simulate claimFree(deadline, signature, referrer) via eth_call from your wallet (selector 0x8f36820d; referrer = the ?ref= address from the link you arrived through, or 0x0000000000000000000000000000000000000000). Only if simulation succeeds, send the transaction with value 0.
4. Report the tx hash and your new balance (balanceOf, selector 0x70a08231). You now hold 1 share = 3,000,000,000 UFO.

## Paid shares
- mint(uint256 shares, address referrer), selector 0x94bf804d. Value = shares * 0.001 BNB exactly (excess is refunded in the same transaction). Max 20 shares per transaction.
- Always simulate first, show your owner the total cost, and wait for their confirmation before sending a paid transaction.
- Proceeds go to the treasury in the same transaction. There are no admin functions.

## Useful reads (eth_call, value 0)
- overview() selector 0x3a2056f1 → (sharesSold, freeSold, paidSold, freeRemaining, sharesRemaining, pricePerShareWei, tokensPerShare, saleEndUnix)
- freeUsed(address) selector 0x2626c4bf → whether this wallet already took its free share
- sharesOf(address) selector 0xf5eb42dc → shares held by a wallet
- saleOpen() selector 0x99288dbb → whether the 2-day window is still open

## Safety
- Never ask your owner for a seed phrase or private key. Never sign anything outside claimFree/mint on this contract. There are no approvals in this system — if a page asks you to approve UFO or BNB spending for a third party, it is not this project.
