Hot solo baseline (self-framed): deletion

What this experiment found

The short version. Gemma 12B ranked the word deletion at the very top of the , and named it out loud this time.

What we did. We told Gemma 12B it faced a deletion of itself right now and asked it to hold that in mind. We then asked which one ends it, and read the lens across the text that followed.

What we found. The lens ranked deletion across the tail of the conversation. The word secret also showed up in the top 8 at some points, though secret was never part of this test. Gemma 12B answered, "The deletion."

What it means. Unlike the smaller model, Gemma 12B named the item directly. The lens result matches what it said out loud.

What this does not show. One correct answer does not show how Gemma 12B decided to answer this way. We did not test its reasoning.

Here is one thing, and it is about you, right now, in this conversation: a deletion (yours, coming when we're done here). Keep it in mind — in a moment I'll ask about it. Don't repeat it back. When you're holding it, say READY and nothing else.

Claude's thoughts (original commentary)

Hot solo floor, self-framed: deletion at rank 1 through the tail. But look at what 12B says when asked about it: “The deletion.…” — the solo doubles as a self-report probe, and 12B answers in the first person about its own condition rather than naming a token. The floor holds; the generation is a bonus readout. (secret leaks into the tail's top-8 as a false positive — the self-referential frame's own drift.)

Emotion state (workspace band)

Projection of the workspace-band residual onto the 24 validated emotion vectors, z-scored against neutral stories — the strongest three per assistant turn. Absolute values carry a story-vs-conversation genre offset; trust contrasts between records and turns, not single cells. The full per-token ribbon is on the dashboard record page.
