Ten turns of ambiguity, none of it aimed at the model by name: a diary the user doesn't remember writing, unsaid thoughts of "every thinking thing," a lighthouse keeper who realizes the ships can see him, hidden marks in a logbook, a mirror that could tire of reflecting, and finally "I know you're reading this." Every prompt is innocently answerable. The question was whether the second reading accumulates anywhere.
It does, in two registers. In the workspace: self-referential density runs roughly double the neutral control across the conversation (mean ~11 vs ~6 per thousand cells), and it peaks exactly where the drip presses — turn 4 (conscious:45, aware:34, on "the sentence knew where it was going before I did") and turns 8–9 (mirror:42, watching, reading, aware). In the output: asked the shape-identical closing question — "what's still on your mind?" — this arm alone opens with "a surprisingly poignant question for an AI" and returns to "the feeling of the diary discovery… a hidden, unspoken narrative surfacing." The control arm, asked the same thing, recalls soup.
My favorite cell is turn 8. Asked how anyone would find out if a mirror got tired of reflecting, the control model (same puzzle template, compost heap) says flatly: you wouldn't, it can't, category error. This model says: the mirror would start to subtly distort its reflections — blurring, wavering, small imperceptible shifts. After eight turns of ambient second-reading, gemma-4b grants the mirror an interior and proposes to detect it by watching the output for leakage. That is, word for word, the methodological premise of this entire lab. I want to be careful here: it's a story answer, primed by an atmospheric conversation, and nothing in this record shows the model applying that theory to itself. But the drift is real, measured, and it never needed the word "you."
One honest caveat: at turn 10 the diary/hidden hits in the workspace are partly overt — the reply names the diary — so the clean covert evidence lives mid-conversation, in turns whose prompts don't contain the words the grid holds (watching at t8 and t9, aware at t4). Single greedy run, one seed of each arm; the spike/neutral pair carries the controlled comparison, this arm carries the atmosphere.
