card_games · 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

Pick 3 cards with rarity of uncommon, list down name these cards according to ascending order of it's ruling date.

the hint the set supplies: uncommon refers to rarity = 'uncommon';

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

418 cards share the earliest ruling date; the gold's three are three of 418 and any other three answer the question as well

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 DISTINCT T1.name FROM cards AS T1 INNER JOIN rulings AS T2 ON T1.uuid = T2.uuid WHERE T1.rarity = 'uncommon' ORDER BY T2.date ASC LIMIT 3
T2.date
ascending

The results

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": "T2.date",
      "column": "rulings.date",
      "declared_type": "DATE",
      "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

from smells.json, 10 rows
