Abstract
This paper presents a Criterion-Based Role-Based Access Control model in which secure permissions (SP), secure operations (SOp), secure objects (SOb), and secure users (SU) are introduced. The security criterion expressions (SCE) embedded in SOb work as locks and the common elements of the security criterion subsets (SCSS) in SOp and SU work as keys. To support web-based applications, the remote secure user-role assignment is done based on user's digital credential(s), and Compact-Secure-Role-SCSS cookies are adopted to simplify the subsequent transactions. The multilayer access control is achieved by actuating locks with the relevant keys. The proposed model, an extension of traditional RBAC, efficiently supports both multilayer access control and non-multilayer access control on the web.

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
