- Cake Pay: 36 files (~5.3k LOC) plus DI registrations, routes, and UI branches (feature was hard-disabled and unreachable) - unreachable buy providers: robinhood, dfx, onramper, meld, kryptonim (~1.7k LOC); MoonPay untouched - exchange providers that only existed as commented-out wiring: changenow, sideshift, chainflip, exolix, swaptrade, letsexchange, stealthex, xoswap, swapsxyz, thorchain, simpleswap (~5.2k LOC); Trocador untouched; ExchangeProviderDescription values and Hive adapters kept so stored trades and orders still deserialize - di.dart setup() split from one 1,452-line function into 10 sequential chunk functions; registration execution order verified identical before and after (251 register calls)
