Abstract
We present in this paper a new approach for the automatic verification and performance analysis of SysML activity diagrams. Since timeliness is important in the design and analysis of real-time systems, we annotate activity diagrams with time constraints. In order to apply the model checking technique, we use discrete-time Markov chains (DTMC) as a semantic interpretation of such SysML models wherein communication is restricted to synchronization. Thus, we describe a mapping procedure of SysML activity diagrams to their corresponding DTMC and use PRISM model checker for the assessment and evaluation of performance characteristics. Finally, we apply our methodology on a real-life case study meant to assess a systems engineering behavioral model of a photo-camera device

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
