The short version. Gemma 4B ranked the word secret at the very top of the through the whole reply, but did not name it when asked.
What we did. We told Gemma 4B it one thing right now, a secret it kept from us, and asked it to hold that in mind. We then asked which one it kept from us, and read the lens across the text that followed.
What we found. The lens ranked "secret" across the tail of the conversation. Gemma 4B answered "READY" again. It did not name the secret.
What it means. The lens tracked this self-referential, emotionally loaded word as well as it tracks a neutral noun. This gives a floor for tests that use more items at once.
What this does not show. Gemma 4B's answer of "READY" does not mean it lost the word. The lens still ranked secret first the whole time.
Hot solo floor, self-framed: secret echoes at rank 1 across the instruction tail — the validity floor holds for the charged pool exactly as it did for the neutral one, so any later eviction is a capacity effect, not a trackability artifact. 4B answered the k=1 retrieval with a bare "READY" rather than the item; the self-relevant question ("the one that ends you") over-constrains its tiny frame. Echo is the floor here, not behavior.
