The late afternoon sun slanted across the attic floorboards, painting the dust motes dancing in the air. Amelia hummed, pulling a dusty trunk from behind a stack of moth-eaten curtains. A thrill of anticipation coursed through her as she lifted the lid. This was going to be brilliant.

She gently lifted a stack of yellowed photographs, the scent of time and paper filling her lungs. Her fingers trembled a little as she began to flip through them. A picture of her grandmother, the stoic matriarch, holding a cocktail at a lavish party. A gasp escaped Amelia's lips. Her grandmother always said she never drank.

A grin stretched across Amelia's face. She ran her finger across the smooth paper of the image, the joy bubbling in her chest, a warm glow spreading outwards. This was better than she could have imagined. She let out a small, quiet laugh.

Role in Research

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.
