Abstract
This paper examines the use of clock distribution architectures employing a reference-based skew compensation technique. For each clock domain, a bi-directional clock line is daisy-chained using specially designed switches at each tap in the distribution. Daisy-chaining the clock decreases the clock load by eliminating the redundant paths used to equalize delays in traditional H-tree distributions. Clock skew is accounted for by actively synchronizing each local clock to a position directly between forward and reverse-moving reference clocks. This reference-based clocking strategy achieves a set of skew-tolerant clocks at each tap in a daisy-chain. The design provides simple-to-layout and scalable multipoint skew compensation useful for large designs. The implementation of a reference-based clocking chain is outlined, followed by the description of single clock and multi-clock architectures using this design strategy.

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
