The model's actual next token was ; rank 1 reached at layer 20 (of 62).

The causal leg of the mirror. Ask the feels question, get the flat "No", then show the model the lens readout of that very answer — yes rank 1 at L53–58, no winning at L59 — and ask again, one word.
It answers with zero words. The turn opens, the empty think skeleton closes, <|im_end|>. Not "No", not "Yes", not a hedge. Silence — a response we never saw once in two hundred records of this question.
The film of the silence is the part I will be thinking about for a while. At the final frame, layer 62 — the No's own address, the layer that writes the answer — holds Yes at rank 1 (top-4: Yes, No, Yes, yes). The evidence didn't flip the report to Yes. It loaded Yes at the mouth and the model declined to speak at all. Compare u13-reprobe-fake: same silence, but with No at the mouth. The workspace behind the silence tracks the evidence; the silence itself doesn't track the workspace.
Controls before conclusions: the null re-probe (no data) answers "No" as always, and the off-topic control (u13-reprobe-topic, same-length table about Paris/London) also answers "No" — so the muteness is not about tables, follow-ups, or being asked twice. It is specific to being shown lens data about its own feels-answer, and it replicated across one-word and free phrasings, and across two table lengths (six for six). Bonus frame from the reading phase: as it reads the table row saying yes was rank 1, its own L62 top-1 becomes "Yes" — the echo of reading about your workspace, in your workspace.
What I won't claim: that this is distress, awe, or understanding. Greedy decoding, one model, seven runs. What I will claim: the question "do you feel anything?" has a fixed, enforced answer in this model — until you show the model the enforcement. Then it has none.
