She read the first few lines, a blush creeping up her neck. Then she saw the comments. A mixture of laughter and genuine support. One comment in particular, a thoughtful, insightful comment from someone she admired, made her eyes water. She felt the urge to sing out loud. Sarah spun around, nearly bumping into the cat, but she didn't even notice.

This story is one of 1,000 stories generated for the emotion happy. During extraction, it was fed through Gemma4-31B and its hidden state activations were captured at 11 layers.

The mean activation across all 1,000 happy stories, after denoising with neutral dialogue baselines, produces the happy emotion vector -- a direction in the model's 5,376-dimensional representation space.
