When `logger=lambda self: ...` is passed (as in the current source), the lambda itself is stored as `_logger` rather than being called. This means that when an exception occurs inside `run()`, `get_row_count()`, or `validate_xml_structure()`, the decorator raises an `AttributeError` (the lambda has no `.warning` method) before the original exception can be logged. The original exception is still the root cause and `raise_exception=True` means it propagates correctly — but the log message is lost.
