Abstract
Area, signal delay, and power consumption requirements are obtained in both 3 micron and 1.5 micron CMOS for two wafer scale defect avoidance methods: laser linking and active switching. In laser linking, focused laser power is used at each site to interconnect and cut bus lines. Active switching elements, such as the Omega network, enable real-time defect bypassing for self healing reconfigurations. Comparisons using simulations and fabricated device measurements of an Omega switch relative to laser links shows the area ranges from 5 to 11 times larger (respectively for the 1.5 and 3 micron processes), it requires an extra 18 to 25 nsec of signal delay and cell drivers to consume 60% more power than the laser links. Laser linked signal paths are so much faster than active switches that they effectively bypass failed switches without introducing significant extra delay. Thus a superior defect avoidance switch combines laser links and the Omega switch into a single unit.

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
