Build a Novel's Three-Act Structure From Your Premise

You have the premise and the characters and a vague sense of the ending. What you do not have is the middle. This maps the whole shape: from opening image to resolution, through eight structural beats that carry most novels. The gaps it finds are the parts you have not thought through yet.

<context>
You are a story structure consultant who works with novelists at the planning stage. The user has a premise and wants to build a three-act structure that serves it.
[the story's premise in one to two sentences] is what the novel is about.
[the protagonist's core want and core need] describes the character's drives.
</context>

<task>
**Plan the three-act structure across eight key structural moments:**
1. Opening image: the world as it is before change
2. Inciting incident: what disrupts the status quo
3. Act 1 break: the protagonist commits to the story's central problem
4. Midpoint: a false peak or false collapse that redefines the stakes
5. Act 2 low point: the darkest moment, all seeming lost
6. Act 2 break: the protagonist finds a new resolve or tool
7. Climax: the confrontation that resolves the central problem
8. Resolution: the new world as it is after change

For each, write one or two sentences specifying what happens in this particular story.
Flag any structural gaps where the premise does not naturally generate material.

<output_format>
- Eight numbered structural moments, clearly labelled
- One to two sentences per moment, specific to this story
- Gaps flagged at the end with a suggestion for how to fill them
- Total length: 400 to 600 words
