R-ORD GOLD-ONLY arbitrary-cut

formula_1 · 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

As of the present, what is the full name of the youngest racer? Indicate her nationality and the name of the race to which he/she first joined.

the hint the set supplies: full name refers to forename+surname; Youngest racer = MAX(dob)

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.

read by hand, 2026-09-07: wrong the gold does not answer its question on this data

the join to the standings repeats each driver once per race, so 14 rows share the largest date of birth and name 14 different races

a maintainer's reading of this question, out of classification.json, copied from plans/reports/bird-dev-sqlite-260907/classification.json. It is not a verdict and nothing above it was computed from it.

The statements

gold

SELECT T1.forename, T1.surname, T1.nationality, T3.name FROM drivers AS T1 INNER JOIN driverStandings AS T2 on T1.driverId = T2.driverId INNER JOIN races AS T3 on T2.raceId = T3.raceId ORDER BY JULIANDAY(T1.dob) DESC LIMIT 1
JULIANDAY(T1.dob)

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

what it measured 
{
  "heuristic": true,
  "reason": "no ORDER BY key resolves to a text column",
  "keys": [
    {
      "key": "JULIANDAY(T1.dob)",
      "not_applicable": "the key is an expression and not a column"
    }
  ]
}

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
