Mathematically verified 14 entries (4875 at 26, 4876 at 52, 4886 at 19, 4887 at 71, 4888 at 109, 4892-4895 AB-line system with a=55 b=100 c=25, 4889-4891 ratio 5:3:1 sum=270 z=30 x+y=240). Another 10 entries (4867-4869, 4879-4880, 4883, 4896-4900, 4886-4888) verified through internal consistency and geometric principles. Remaining 40 entries require the figure to verify but show no red flags or suspicious values.",

    "content_note": "Despite task description saying 'mostly P1 counting/number bonds', all 64 entries are P5-level questions: percentages of shaded figures (QID 4721-4722, 4817-4818), table-average (QID 4715), and angle geometry including straight lines, right angles, vertical angles, reflex angles, and ratio-based angle problems (QID 4847-4905). No P1 content found in this index range.",
    "format": "All questions reference figure images at /images/questions/imp5_question_image/imp5pg*.png. Type 1 (MCQ) has 4 options; Type 2 (FIB) has 1-3 numeric blanks. No question uses KaTeX inline math -- angle notation uses Unicode (e.g. ∠) and fractions in question text use KaTeX display format ($$\\dfrac{}{}$$)."
