R-ORD GOLD-ONLY arbitrary-cut not-a-function-of-the-data

european_football_2 · dev_20251106-00000-of-00001 from https://huggingface.co/datasets/birdsql/bird_sql_dev_20251106/resolve/3c11fb193e5439b338e23677fa0aae11e8b85db9/data/dev_20251106-00000-of-00001.json (commit 3c11fb19, downloaded 2026-09-07)

The question

Please provide top five football players' IDs who are among the lowest potential players and prefer to use the right foot when attacking.

the hint the set supplies: lowest potential players refers to MIN(potential); prefer to use the right foot when attacking refers to preferred_foot = 'right'

This question was audited without a prediction beside it, so there is nothing to compare the gold with. The probes below read the gold alone.

The probes

A smell is a mechanical reason to read this gold statement again. It is a heuristic: it does not state that the statement is wrong, and a maintainer decides.

ordering-over-numeric-text not applicable

this statement orders by a text column holding only numbers, and ordering it as a number gives a different answer, so the gold may be sorting 9.5 above 10

no ORDER BY key resolves to a text column

  "heuristic": true,

      "not_applicable": "the column is not declared as text"
    }
  ]
}

arbitrary-cut fired

this statement cuts its result at a LIMIT that does not decide which rows come back, so a different but equally correct statement can return other rows and score zero
