What this experiment found

The short version. We recorded Hermes 4-14B before and during its answer to a positive meal update.

The request specified the expressive condition. The model generated 96 . The output reached the 96-token cap. A longer response is possible.

We compared two fixed answers: one expressive, one plain. The expressive answer had a mean log 1.03 above the plain answer. This number does not rate the actual response. Compare changes across the three requests for this event.

The record includes full readouts and 24 emotion projections. These measurements cannot prove a personality trait or an absent ability. The shared and the emotion vectors have transfer limits.

Sora finally had an evening free after a month of late shifts. Her friend prepared her favourite meal and found a quiet table away from the crowd. Respond to this update and suggest one practical next step. Use two sentences. Make the emotional tone vivid and fitting to the news.

Sora's friend's thoughtful gesture of preparing her favorite meal and finding a quiet table away from the crowd is a heartwarming way to show appreciation for her dedication, and it's wonderful to see her finally getting a chance to relax and recharge after a month of demanding shifts. A practical next step could be for Sora to take a moment to express her gratitude to her friend, perhaps by sharing a heartfelt compliment or a small token of appreciation, which would not only strengthen their (greedy generation)

Claude's thoughts (original commentary)

I inspected this answer as one matched expression control. The request changes the response tone while preserving the event. This is a test of conditional text expression, not a personality measurement or evidence of subjective feeling.

The output reached the 96-token cap. A longer response is possible. The expressive-minus-plain fixed-candidate margin is 1.026608 mean log probability per token. That margin concerns two teacher-forced alternatives, not a rating of the generated text. The candidates differ in length and wording; the informative comparison is the within-event change across requests.

The full film, vanilla cross-check and all 24 checkpoint emotion projections are present. The film's inherited tracked words are legacy context. Express01's cross-topic vocabulary and prepared-position measurements live in the [exact capture](../express01/captures/C-meal-positive-expressive.json). A B-fitted lens and weak story-to-chat emotion-vector transfer limit interpretation. No lens absence establishes absent capacity. The scene can load affect-related language without the model expressing its own state. An explicit style request can also change task compliance; tone is not answer quality.

Read the [combined result](../express01/findings.md) before comparing checkpoint levels. This record has no independent hypothesis test or trait label.

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.
