Cascade noise, not a distinct failure: marimo marks every descendant of a failed/stopped cell with its own error output ('An ancestor raised an exception' / 'ancestor-stopped'), and the filer treated each as a separate signature. Since cc094bd nb_integration.parse_snapshot drops cascades, so only the root-cause issue for this notebook stays open. This signature will not be reported again.
