    "6126": "WEAK SOLUTION: Question asks to count animals (answer: 11). Solution reads \"Count all the animals shown in the picture. There are 11 animals in total.\" which merely restates the question and answer without teaching any counting strategy. For P1, should teach: count one-by-one (1,2,3...11), or make-a-ten strategy since the question references making 10. Add a labelled counting diagram or at minimum list the count sequence. Also: all 28 questions in this batch have BROKEN HINTS \u2014 hint_text contains literal \"Array\" strings or bare question IDs instead of actual hint content."

    "answers_verified": "All 28 stored answers are mathematically correct",
    "hints": "ALL BROKEN \u2014 For q6039-q6054 (indices 155-174), L1 hint_text = bare question ID (e.g. \"6039\"), L2 = literal string \"Array\". For q6055-q6149 (indices 175-182), L1 hint_text = literal string \"Array\". None contain usable hint content. This is a systematic data bug affecting the entire batch.",
    "format": "All solutions are plain text with <br> tags. None use KaTeX ($...$) math formatting per SOLUTION-STYLE-SPEC. None include bar-model or number-line diagrams. For P1 counting-back subtraction this is marginally acceptable since the questions themselves provide the diagram, but upgrades to KaTeX (e.g. $8 - 3 = 5$) would improve readability.",
    "duplicate_options": "q6045 and q6046 both have answer choices [\"1\",\"2\",\"2\",\"3\"] with duplicate \"2\" values. This does not affect correctness (the right answer is 3 and 1 respectively, both unique among options) but is a data quality concern."
