Spending: a Lightning receive is one row. The ASP settles it as an arkoor the wallet claims — recorded as ln-receive, without its coin's id — and the same coin can reach the mailbox too, which (seeing no movement for that coin) recorded a plain receive as well: two "Received 1,005" rows and a "Payment received! 2,010" (The Daniel). The claim now stamps its coins' ids on the ln-receive, the mailbox backfill counts them, and lnFoldedIds leaves a receive of a claimed coin out of history, the celebration, the arkMovements hook and the LN tagging — derived at read time, never deleted, so a synced copy can't bring the twin back. Claims recorded before the stamp match by amount within ten minutes. tools/ln-receive-twin-test.js
