- Replace getattr(self.session_store, '_db', None) with self._session_db (the GatewayRunner's own SessionDB, consistent with existing usage in slash_commands.py L240/L499). - Remove verbose comment referencing a branch name as an issue number. - Update stale comment in run.py that said 'today it has no session_db'. - Add regression test verifying session_db is passed and rotated session is persisted (adapted from #51624 by @LeonSGP43). - Add _session_db=None to _make_runner fixtures in test_compress_command, test_compress_focus, and test_compress_plugin_engine.
