A model is asked to summarise a profit and loss account carrying one misstated subtotal. Asked only to summarise, haiku-4-5 and sonnet-5 miss it 20 of 20 and repeat the wrong figure as fact; one added clause takes both to 10 of 10. opus-5 and fable-5 catch it unprompted. With the defect at 30-50% and no added clause, haiku-4-5 stays at 0 of 10 and sonnet-5 reaches 6 of 10. 240 calls, zero false alarms across 120 clean reports.
