The tester with 233 sats gets to spend them: invoice coverage judges the SUM of spendable coins (the single-coin gate silently declined anything over the largest coin, though multi-input pays gather 24), an uncoverable invoice now owns its paste — board the shortfall from Savings, or say what's short — instead of dropping the bolt11 into the address field like a dead click, and chain calls gain a last-resort relay through the registrar (/esplora passthrough, tip cached) for the network that blackholes every public esplora
