HRBench8K in this pool kept only one CircularEval rotation, so all 151 answers are 'A' and always-answering-A scores 100%. HRBench8K is the only affected benchmark (verified: sole file with a cycle_category column, a constant answer, and index gaps of 4).
HRBench8K_rotation_fix.tsv re-deals one rotation per question, balanced (A:38 B:38 C:38 D:37, majority class 25.2% = chance). Join on `index` and override answer/A/B/C/D; the base64 `image` column is unchanged, so the 2.3GB of images need no re-upload. Question/options/answer are identical across all five rungs (verified 151/151), so one file serves every resolution. Correct answer CONTENT is unchanged for all questions; original_answer and cycle_category preserve provenance.
