- AppPaths: data-root resolution, per-network paths, wallet file listing. - TransactionFactory: legacy/P2SH/segwit destinations, multi-UTXO selection, dust change absorbed into fee, and a golden txid for the PSBT signing path (RFC 6979 makes it deterministic; the builder's own output shuffling for privacy makes anchoring the vector at the top-level Build() unreliable). - PropertyTests: Slip132 roundtrip for every script kind and network, WalletDocument JSON roundtrip with arbitrary labels/contacts, Scripthash cross-checked against an independent SHA-256 computation. - StorageTests: regression cases for the IsEncrypted fix. - Removed CS8602/CS8604 nullable warnings from existing address/loader tests.
