  "message": "Keep `weighted_distribution_` in sync with `records_` when pruning all-zero weights.\n\nWhen all corpus inputs have weight zero, `WeightedDistribution::RemoveRandomWeightedSubset` removes every entry from `weighted_distribution_` before returning `subset_to_remove`. `Corpus::Prune` then erases one index from `subset_to_remove` so `records_` retains one random input, leaving `weighted_distribution_` empty and causing check failures on subsequent corpus operations.\n\nRestore one zero weight in `weighted_distribution_` when keeping that fallback input, and add a unit test covering `Corpus::Prune` with all-zero weights.\n\nPiperOrigin-RevId: 1002585725\n",
