Abstract
Recently, a new, very efficient method of multilevel logic synthesis based on factorization and decomposition of Boolean expressions has been introduced. It has been shown that the transformations used by this method preserve the single stuck-at testability of two-level circuits. This paper shows that single-cube extraction, double-cube extraction, and dual-extraction of double-cubes/spl isin/D/sub 1,1,2/ and D/sub 2,2,2/ preserve testability with respect to a general robust path-delay-fault (RPDF) test set. However, the authors show that while dual-extraction of double-cubes/spl isin/D/sub 2,2,3/ preserves RPDF testability of paths through the extracted divisors with respect to a single-input-changing test set, it does not guarantee RPDF testability preservation of unmodified paths. Furthermore, the authors provide sufficient conditions for algebraic resubstitution with complement to preserve RPDF testability that cover a larger class of complementary expressions than was known previously. The testability preservation of these transformations is demonstrated on a set of RPDF testable Berkeley PLAs.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

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
