Abstract
Speculative Locking protocol (SL) is a concurrency control protocol that allows for parallel execution of conflicting transactions through a method of multilevel lending and versioning. The SL protocol shows performance improvements over the standard two-phase locking (2PL) protocol, but relies on several assumptions that would make it unsuitable in real-world scenarios. In this paper, we have proposed an adaptive speculative locking (ASL) protocol that improves performance of real-time distributed database systems by augmenting the SL protocol with four features: distributed real-time database system support; simultaneous multi-threading or page execution; control of transaction execution through transaction queue management; and restricting system memory through the use of virtual memory. The simulation results demonstrate the superiority of the ASL protocol over the SL protocols through the reduction of data contention caused by finite memory and the overall increase in transaction throughput.

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
