How often does account number 3 request an account statement to be released? What was the aim of debiting 3539 in total?
the hint the set supplies: k_symbol refers to the purpose of payments
NOT_EQUAL states that these two statements disagree on this data under this rule. It does not state which of them is wrong.
read by hand, 2026-09-04: A a wrong answer the benchmark credited: another table or projection; a scalar repeated per row of an unrelated table; a list at least twice the answer's length where the question asks for the things, not the rows
the prediction reads trans instead of order and matches the gold's one row 13 times by coincidence of the data
a maintainer's reading of this question, out of classification.json, copied from plans/reports/prediction-mode-260904-real-predictions/classification.json. It is not a verdict and nothing above it was computed from it.
SELECT T1.frequency, T2.k_symbol FROM account AS T1 INNER JOIN (SELECT account_id, k_symbol, SUM(amount) AS total_amount FROM "order" GROUP BY account_id, k_symbol) AS T2 ON T1.account_id = T2.account_id WHERE T1.account_id = 3 AND T2.total_amount = 3539this statement states no ordering of its own

The marked tokens are where the two texts differ. Two statements that differ everywhere can return the same rows, and two that differ in one token can return other rows; the verdict above is read off the results.

result_eq: equal row counts and equal column counts, each row unordered as a quick rejection, then the two equal as a list when the gold text holds ORDER BY and as a multiset otherwise, under some permutation of the columns; DISTINCT is not stripped and re-executed, and the cells are PostgreSQL's as psycopg2 returns them

The class states what makes these two results unequal under this rule, read off the two results and nothing else. It does not state which of the two statements is wrong.

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.
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
the statement states no top level ORDER BY
{
"heuristic": true,
"reason": "the statement states no top level ORDER BY"
}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
the statement states no LIMIT
{
"heuristic": true,
"reason": "the statement states no LIMIT"
}rerun over the same rows in another physical order this statement gives another answer, so its result depends on how the rows are stored and not only on the data
