If the read fails, val_v remains\nuninitialized and its random stack content is subsequently reported\nas a measurement result.\n\nInitialize val_v to zero to ensure a predictable value is reported\nin case of bus failure and to prevent potential stack data leakage.\nThis also satisfies static analyzers that might otherwise flag the\nvariable as used uninitialized.",
