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

student_club · 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

What are the expenses of the budget with the lowest remaining?

the hint the set supplies: expense of budget refers to expense_description; lowest remaining refers to MIN(remaining)

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

two budgets share the lowest remaining amount and carry different expense descriptions; the question asks for expenses and the gold returns one

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 T2.expense_description FROM budget AS T1 INNER JOIN expense AS T2 ON T1.budget_id = T2.link_to_budget ORDER BY T1.remaining LIMIT 1
T1.remaining
ascending

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": [
    {

      "declared_type": "REAL",
      "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
