When an AI scene rewrite breaks the next scene

Ask the AI to rework one scene and it reads the whole story but writes only that scene. The rule is right, and it was reading less than we thought.

The scenes it could see stopped at the sequence boundary, so the first scene of nearly every sequence was written with no sight of the scene before it. That is exactly where a reader notices a change of voice in a screenplay, so the model now sees real neighbours in story order, and the page-writer's instructions carry more of that work.

That surfaced the harder question: what happens when a good rewrite breaks the scene next door. Scene 11 ends with Rosa driving away. The rewrite has her arriving on foot in scene 12.

The answer is not to allow it. It is to require a declaration first. The model may touch a named neighbour, but only if it says which one and why, before it does it. "You may edit what you justified" is a rule you can check against what comes back. "Edit wherever you judge there is discord" is not a rule, because an overreaching model will call its own overreach discord and believe it.

You see every crossing before it lands, each with its own checkbox. Past four repairs in one pass, every further one is refused. A rewrite that needs that many repairs is doing something else.
