Abstract
Protection domains are one of the most enduring concepts in Access Control. Entities with identical access control characteristics are grouped under the same protection domain, and domain-based policies assign access privileges to the protection domain as a whole. With the advent of the Internet of Things (IoT), devices play the roles of both subjects and objects. Domain-based policies are particularly suited to support this symmetry of roles. This paper studies the mining of domain-based policies from incomplete access logs. We began by building a theory of domain-based policies, resulting in a polynomial-time algorithm that constructs the optimal domain-based policy out of a given access control matrix. We then showed that the problem of domain-based policy mining (DBPM) and the related problem of mining policies for domain and type enforcement (DTEPM) are both NP-complete. Next, we looked at the practical problem of using a MaxSAT solver to solve DBPM. We devised sophisticated encodings for this purpose, and empirically evaluated their relative performance. This paper thus lays the groundwork for future study of DBPM.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
