  "abstract": "Representation comparisons are commonly published from one split at one seed on uncurated public sets. Repeating one, the count of endpoints whose best featurizer changes with the split read three, one, one and three under two choices, seeds and deduplication, and every reorder lay between arms whose intervals overlap. Only the fingerprint baseline separated anywhere, by being worse; duplicates placed up to 3.8% of random-split test rows in training. A four-step remedy is given.",
