Research direction
Start with electrum/lnwatcher.py, especially list_sweep_tx around line 73 and its caller near line 327, then inspect electrum/sql_db.py:49. Use the watchtower dialog path in electrum/gui/qt/watchtower_dialog.py to understand when the query runs. Done means identifying and preventing the reported disk I/O failure, with a regression test if the failure can be reproduced.
