Abstract
Feeling the pinch: Remarkably facile SiC(sp3) and SiC(sp2) bond cleavage processes occur in [(CyPSiP)M(alkyl)] species (M=Ni, Pd; see picture); in the case of Ni, these SiC bond activation processes are reversible on the NMR timescale in solution. Such examples of metal-mediated cleavage of an unstrained SiC(sp3) bond are extremely rare and are unprecedented for Ni.

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
