Same woman. Eight worlds. Nothing else survives the trip. Most AI character sets lose the person by the fourth frame. Not because the model is bad — because "the same woman" is not a lock, it's a wish. What actually holds a face is a short list of things you name and then refuse to change: a split brow, freckles on one cheek only, a gap in the teeth. Cheap to write. Almost impossible for a model to invent by accident. So we locked one face and sent her somewhere new eight times. A lemon market at noon. A coral wall in hard sun. Under a sheet of water. Forty pixels tall in an empty stadium. Frame seven is the one worth stealing: put her in front of a mirror. Her face renders twice inside a single photograph. If the two disagree the frame is dead, and nothing else in your workflow will ever tell you. Comment UNDERSTUDY for the 8 scene prompts and the identity lock that held her across all of them.
