+// Two wakes of the phone's worker, seconds apart, each over its own copy of
+// the wallet, both drive one Lightning send (PullCap, 2026-10-24 23:21). The
+// second's InitiateLightningPayment is refused — the HTLC is already 'ln-spent'
+// to this very payment — and that once marked a PAID send 'revoking'. Now the
+// send follows the payment instead, and a send in 'revoking' asks the ASP
+// before revoking: paid → settled; still in flight → back to waiting.
+// Run: bun test tools/ln-pay-double-wake.test.js
