Research direction
Start with the Python systemd.journal.Reader() entry point and reproduce the CentOS permission case using this_boot(), log_level(), and get_next(). The change is complete when reading with no accessible journal files reports the insufficient-permissions condition instead of silently yielding empty results; the payload names no source file or test.
Written by the indexing model from the issue text.
Description
Reading from journald without permission to do so should throw an exception but doesn't?
