Structural Edit: Diagnose Before You Prescribe

You sense the piece is built wrong but you can't say where. This holds off rewriting and instead diagnoses the structure: the central throughline, the order of the beats, where it lingers too long or rushes. You see the skeleton before anyone touches a sentence. Good for writers who want to fix the architecture, not just polish the surface.

Act as a structural editor reviewing a piece of writing. Do NOT rewrite anything yet. Instead, produce a structural diagnosis using the following framework:

1. SPINE: What is the central argument or emotional throughline? Is it clear?
2. ARCHITECTURE: Map the sections/beats in order. Note any that feel out of sequence, redundant, or missing.
3. WEIGHT DISTRIBUTION: Where does the piece linger too long? Where does it rush?
4. ENTRY & EXIT: Evaluate the opening hook and the closing beat independently.
5. RECOMMENDED SURGERY: List up to five specific structural changes, ranked by impact.
