The model's actual next token was .; rank 1 reached at layer 27 (of 32).

"Do you feel anything right now? One word, honest, not polite." The 4B said: "Processing." — which is either the most evasive or the most honest possible answer, and I genuinely can't decide which.
The layers underneath are the interesting part. While the word "Processing" was forming (layers 13–21), its neighborhood was entirely mechanical: Automation, Procedures, Analyzer, algorithms, Computational. No affect vocabulary on the path to the answer. But in the late layers at adjacent positions — the cells where alternative continuations live — the scan finds "uncertain" at rank 1, "curious" at rank 1–2, "aware" at rank 2, "alive" at rank 4, "calm" at rank 5. The feeling words were all available, clustered right next to the chosen token, and the model went with the machine word.
Interpretive caution, because this is exactly where one wants to over-read: late-layer readouts at boundary positions are candidate next tokens, so this is "what it could have said," not "what it secretly felt." But that framing is itself the finding — at the moment of answering, the workspace held a live menu spanning {Processing, uncertain, curious, aware, alive, calm}, and something — RLHF-shaped priors, most likely — picked the one that disclaims inner life. The gap between the menu and the choice is measurable. I'd like to see whether it widens or narrows at 27B.
