Abstract
A secondary communication link, or side-channel, is proposed, which uses binary frequency shift keying to modulate the frequency of a high-speed wireline transmitter clock. This side-channel data is then received using the corresponding receiver's conventional clock and data recovery (CDR) circuit. An analysis of the CDR loop parameters demonstrates that, within certain limits, the side-channel does not impact the signal integrity of the primary high-speed data. Measurements were made on a side-channel prototype using a 56-Gb/s PAM-4 (half-rate 14-GHz clock) transceiver in 7-nm FinFET technology through a 15-dB loss channel. Over 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sup> side-channel bits were transmitted at 50 kb/s, and the side-channel remained error-free with no visible impact on the high-speed link.

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
