Abstract
K. Tatsuoka's rule‐space model is a statistical method for classifying examinees' test item responses into a set of attribute‐mastery patterns associated with different cognitive skills. A fundamental assumption in the model resides in the idea that test items may be described by specific cognitive skills called attributes which can include distinct procedures, skills, or processes possessed by an examinee. The rule‐space model functions by collecting and ordering information about the attributes required to solve test items and then statistically classifying examinees' test item responses into a set of attribute‐mastery patterns, each one associated with a unique cognitive blueprint. The logic of Tatsuoka's rule‐space model, as it applies to test development and analysis, is examined an this module. Controversies and unresolved issues are also presented and discussed.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
