Inputs, prompt conditions and scoring

What the model receives

The concept-to-brief pack fixes the creative starting point so models can be compared on developing the narrative. Coverage differs by model and repeat count; repeated versions of this pack do not represent independent audiences or brands.

What changes between prompts

The same fixed creative input and brand context are used with plain and scaffolded-context prompts. The structured condition adds guidance for developing the output. The publisher keeps hooks, narratives and compliant briefs as separate tasks, with their own scores.

How the result is scored

The narrative score averages coherence, commercial persuasion, use of emotional levers and product relevance. This measures the written narrative. The hook and the production handover have separate task scores, so a high narrative result is not inherited by the whole workflow.
