Research direction
Start with the traceback in electrum/gui/qt/send_tab.py and electrum/gui/qt/confirm_tx_dialog.py, then follow the transaction path into electrum/wallet.py, electrum/transaction.py, and electrum/descriptor.py. Reproduce payment confirmation with an imported wallet and trace why descriptor expansion reaches a missing key object; done means the affected flow no longer raises this AttributeError.
