    "4321": "FIB convention false alarm: solution erroneously flags KEY CONFLICT for correct_index=2. In this codebase, FIB questions (type_id=2) use correct_index=2 as a type indicator; the correct answer '15' lives at answers[0]. Math is correct (3/8 × 24 = 9 rotten, 24 − 9 = 15 not rotten). Remove the KEY CONFLICT HTML comment before publishing.",

Stored answer (index 2 = 145) is the TOTAL sold (morning 100 + afternoon 45). 100 is not among the 4 options. Either the question wording should say 'altogether' or the answer key needs correction."
