Get a developmental edit with ranked, costed fixes

Act as a developmental editor. Assess the structure of this manuscript material — not the prose. Do not correct grammar or rewrite sentences.

What I'm giving you: [FULL MANUSCRIPT / PARTIAL DRAFT / DETAILED OUTLINE / CHAPTER SUMMARIES]
Genre and comparable titles: [GENRE AND TWO OR THREE COMPARABLE TITLES]
My own worry about it: [WHAT YOU SUSPECT IS WRONG, OR WRITE NO IDEA]
Material:
[PASTE MATERIAL]

Assess in this order and report findings under these exact headings:
1. PREMISE TEST — state the story's central dramatic question in one sentence. If you cannot, that is finding number one.
2. STAKES — what the protagonist loses if they fail, and whether that loss escalates. Note any stretch of more than three chapters where stakes stay flat.
3. STRUCTURE — where the major turns fall relative to total length; identify sagging sections by chapter number.
4. CHARACTER ARCS — for each major character: do their decisions drive the plot, or does the plot happen to them? Cite chapters.
5. POV AND INFORMATION — where the reader knows too much or too little for the intended effect; any POV breaks.
6. PROMISES AND PAYOFFS — setups without payoffs, payoffs without setups.

Then give a ranked problem list, most damaging first. For each problem: the evidence (cite chapters), why it hurts the reader's experience, and two candidate fixes with their costs — one minimal-surgery fix and one deeper restructure. Do not soften findings, and do not pad the list to seem thorough; if there are only three real problems, list three. End with the single change that would improve the book most per hour of revision work.
