# Inputs, assets and dependencies

## Provided inputs

- `inputs/dispatch-prompt.txt`: full initial controller dispatch, preserved verbatim.
- `inputs/01-v8-cutaway.md`: exact original source brief, copied before implementation. It includes a short comparison variant, a directed production brief, and an unused comparison contract; only the directed production brief was built.
- Current interactive working agreement and the controller’s local-only/no-publication limits influenced execution. There were no human follow-up corrections during the initial build.

The brief cites [Dilum Sanjaya’s public V8 example](https://x.com/DilumSanjaya/status/2096280244663775423) as inspiration. No code, mesh, screenshot, private prompt, audio or other asset was copied from that example. This is an original pilot, not a recovery or reconstruction claim.

## Original local assets

All engine meshes, cutaway surfaces, fasteners, rods, piston rings, valves, springs, lobes, chain envelope, diagrams, UI and shadow texture were procedurally authored in this task. The mark is plain typographic “im”. No stock assets, downloaded media, paid generation, image-generation model, TTS or music service was used.

Arial/Helvetica and Georgia/Times New Roman are system-font fallbacks; no font files are bundled or fetched. Lucide supplies functional interface icons. Three.js RoomEnvironment supplies a generated studio environment from its open-source library; it is not a sourced HDR photograph.

## Software

The complete dependency graph is frozen in `project/package-lock.json`. Main dependencies: Three.js 0.180.0 (MIT), React / React DOM 19.2.6 (MIT), Vinext 1.0.0-beta.5 (MIT), Vite 8.0.13 (MIT), Base UI 1.7.0 (MIT), Shadcn React 0.3.0 (MIT), Lucide React 1.31.0 (ISC), Playwright 1.58.2 (Apache-2.0). Sites scaffold: `@openai/create-sites@0.3.0`, with Shadcn add-on. FFmpeg 8.1.1 performs local MP4 encoding. Existing Chrome 152.0.7977.76 supplies the browser runtime.

Third-party code retains its upstream license terms. `project/THIRD-PARTY-NOTICES.txt` includes the notices for the principal shipped browser libraries. Technical reference facts and derivations are documented in `MECHANICS.md`.
