Dreamer is a world engine you can talk to. Give it a book, one sentence, or a real address, and it builds a walkable 3D world and stages a living scene inside it. The characters have their own voices and bodies. They can act the book as written, or switch to freestyle, where the director and the characters improvise around you and you whisper the director what should happen next.

The problem: making an interactive 3D story today takes a studio and months. Image and video models can paint a pretty frame, but you can't walk into it, and the room bends when you turn. We wanted the opposite: a space that stays solid, at real scale, built in minutes, that keeps going after the script ends.

How it works. Muse Spark reads the source and writes a brief: places, cast, what each scene wants. Dreamer looks up real references for every place instead of trusting the model's memory. Then the work is split three ways. Code builds the space: geometry in meters, doors, placement, rotation, navigation. Muse Image paints only surfaces: seamless wall, floor and ceiling tiles and flat decals like windows and paintings. SAM 3D makes every object as a real mesh, one GPU per object, all in parallel. Critics compare screenshots of the build with the references and send fixes back. A director keeps the scene alive: characters, voices, camera, subtitles.

What the video shows (the first three run locally from Dreamer Home; the fourth is live for judges below):
- Koshakan: a fairy tale my wife wrote for our daughter, played as a book in its bedroom, bathroom and meadow.
- Sherlock's 221B Baker Street, played as written or improvised.
- Create: type or say an idea ("Mirai finds a tiny lost kitten in the meadow"), and Muse Spark writes a new chapter with that world's cast and stages it in the ready world. Measured: 3 min 04 s, $0.07.
- Kozbagarov St. 7: a real yard in Semey, Kazakhstan, rebuilt from OpenStreetMap, satellite and Street View. Hold Space and say what should open there. Meta ASR hears you, and a shop grows into the first floor of the house. Cold-GPU build measured at 184 s and $0.50.

Live build for judges (please don't share): https://highskilltero--semey-web.modal.run/?live&k=55524e74ac55ede5
Open it, walk with WASD, hold Space and say what should open in one of the free places. The key is in the link. The world has four free places (one build each) and a hard money cap, after which it turns view-only.

Built solo in 9 days (repo history starts Oct 27). Every hypothesis was measured before we built on it; the log with numbers is in RESEARCH.md and DEVLOG.md.
