Riproduci il problema con l’archivio dei risultati collegato, quindi parti da openfecli/commands/gather.py in _write_dg_mle e segui la chiamata fino a cinnabar/stats.py:mle. Investiga gli avvisi di divisione per zero e il fallimento di SVD; il lavoro è concluso quando il percorso gather gestisce questo input o lo segnala chiaramente senza l’eccezione non gestita attuale.
