A warehouse receives 3 pallets. Each pallet holds 48 boxes and each box holds 12 units. On inspection, 15% of the boxes are damaged; round the number of damaged boxes down to a whole box. The damaged boxes are discarded. Then 7 undamaged boxes are sent to the quality lab and are not sold. How many units are left to sell? Reply with only the number.
Rubric for the judge: The single correct answer 1392 (144 boxes, 21 damaged, 7 to the lab, 116 x 12).
Every cell is one OpenRouter call at temperature 0 with the prompt's token cap and reasoning effort "low" where the model supports it. Cost is usage × the catalogue rate in models.json. Quality is one judge call to anthropic/claude-haiku-4.5 against the prompt's rubric, cached per prompt version.
