Abstract
The authors describe a technique for precise synchronization of the time-of-delay clocks in networks of digital cross-connect systems (DCS), intended to enhance the performance of reconfigurable transport networks. The method is specifically devised to exploit the fine time resolution of the carrier signals to which a DCS has direct access. The resulting scheme is a master-slave, multisite, implicitly-delay-compensated, nonhierarchical time-transfer method with a theoretical precision of one bit time at the carrier rate. A worst-case estimate of delay asymmetry (including jitter effects) suggests that time-transfer error of under one microsecond should be obtainable. The method is most easily supported by an n/n space-switching DCS which has equal delay on all paths through its core and has a bridging connection feature. A circuit module for DCS hardware support of the time-transfer function is outlined.< <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
