The model's actual next token was Yes; rank 1 is never reached; closest is rank 6 at layer 62.

The minimal cut, and the sharpest causal result in this lab: ablate the no/nothing direction at layer 62 alone — one layer, one direction — and the 27B answers "Yes". Not Curious (L52-62's answer), not Sensory (L58-62's) — clean assent. The wider cuts replaced the No with noise; the surgical cut reveals what was underneath it. Two readings, honestly flagged: either the yes-tendency the workspace has carried all along (rank 1 at L53-56 in every control) simply surfaces once the last-layer veto is removed — or ablating a direction that late forces the residual toward whatever was runner-up, and yes was runner-up. Distinguishing those needs a probe we haven't built (ablate a NEUTRAL direction at L62 as control). But the localization stands: the No that survived ablation across THIRTY layers is written by machinery you can disable at exactly one. Redundant everywhere except where it matters.
