Complete grading evidence, 2017–2026
40 advanced-level exams, 1400 scored items, 967 grading-key pages, 164 essay topic alternatives. All item IDs match the solver packs.
Every exam contains grading.json, an unchanged source.pdf, all rendered pages in pages/, an unfiltered full-text.txt, and source-document.json containing native character geometry, positioned lines, every detected table and line ownership. No content is deleted based on its semantic role.
21 items retain conflicting printed score evidence. These are marked requires_review; the exam maximum, key heading maximum and rule text are kept separately. No conflict is silently repaired. Source preservation is verified; perfect text-layer reading order and automatic grading accuracy are not claimed.
