Abstract
Abstract Shannon entropy is a useful criterion for measuring the uncertainty (predictability) of lifetimes of engineering systems. In this work, we provide an explicit expression for the entropy of the residual lifetime of a working used system with exactly i failed components at time t , using dynamic signature. We also present additional results on bounds and ordering properties for the proposed entropy. We find an expression for the Jensen‐Shannon (JS) divergence of the residual lifetime of a working used system, and show that the JS divergence of the system is equal to that of its dual. An improved bound for the JS divergence is also obtained. Finally, based on the proposed entropy, we introduce a criterion using which we can prefer a system. This criterion, a distribution‐free measure that only depends on the dynamic signature, ranks systems based on their closeness to extreme systems.

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
