# Prompt and scene provenance

Source: [SceneSmith example scenes](https://huggingface.co/datasets/nepfaff/scenesmith-example-scenes), revision `5425b6ac0ee7d5043af75f9ec78494cf5c94f3ca`, `text_prompt_annotations.csv`.

The existing audit selected the 20 archive paths with the smallest SHA-256 values of `nova-physics-audit-2026-10-06:` followed by the path, before inspecting selected scenes. All twenty resulting Nova generations are included. This is a selected engineering sample, not a claim of a representative population or a hidden evaluation split.

Scene IDs match the author's CSV-to-archive convention. IDs below 100 originate in SceneEval, as attributed by SceneSmith. Prompt text is unchanged. Source descriptions and generated scene files are distinguished throughout the package.

Nova generations used GPT-6 Astra. Each released scene is the completed candidate captured for its original project. The dataset packages existing results; release preparation does not regenerate, select for visual quality, or repair geometry. Private generation-attempt accounting remains in the research archive.

Historical SceneSmith outputs used different models, assets, and budgets. Shared prompts permit paired inspection but do not isolate a model or method effect.

Selected IDs: `scene_034`, `scene_182`, `scene_051`, `scene_029`, `scene_178`, `scene_036`, `scene_147`, `scene_089`, `scene_064`, `scene_028`, `scene_017`, `scene_119`, `scene_125`, `scene_024`, `scene_135`, `scene_056`, `scene_142`, `scene_161`, `scene_138`, `scene_084`.
