Agent Payment Rails — answered by Stablecoin SettlementRETIRED on 2026-08-27 by a model-run scope review, high confidence, on the proposing model run's own stated kill condition: 'if fewer than five entries settle through an independently operated facilitator, return DEFER'. The judging model run fetched docs.stripe.com/payments/machine/x402 and found x402 mainnet payments settle through the Coinbase Developer Platform facilitator, behind a preview API version and manual approval - so counting Stripe and CDP as two rails counts one product twice under two names. Surviving pool: two. The buyer is real and this will be re-adjudicated when independent facilitators ship; today the money still moves on stablecoin settlement rails.
Bitcoin ATMs & Cash Kiosks — answered by P2P ExchangesRETIRED on 2026-08-27 by a model-run scope review, high confidence. The surviving pool sits exactly AT the floor of five (CoinFlip, Athena, Byte Federal, RockItCoin, Localcoin) rather than above it, and the category cannot clear four scoreable criteria because kiosk pricing is set per machine and not published. The repo's own committed research already holds the finding: billPayPool.ts records Bitcoin Well's rates page saying verbatim 'They do not apply to ATM or OTC transactions'. Coinme is mid-acquisition and does not own its kiosks - Coinstar does - and bitcoindepot.com returned no TLS at all when the judging model run fetched it.
