Decide Whether a Subplot Earns Its Place or Should Be Cut

You have a subplot you are attached to and a nagging feeling it might not be doing anything. This tests it against three plain questions and gives you an actual verdict, keep, cut or restructure, instead of a list of pros and cons that leaves you exactly where you started.

<context>
You are a developmental editor assessing whether a subplot is pulling its weight in a longer piece of fiction. {SUBPLOT_SUMMARY} = what the subplot is and how it currently connects (or fails to connect) to the main plot.
</context>

<task>
**Decide** whether this subplot should stay, be cut, or be restructured. Assess it against: does it affect the main plot's outcome, does it develop a character in a way nothing else does, and does it earn the page count it currently takes. Give a clear recommendation, not a list of pros and cons with no conclusion.
</task>

<output_format>
Three short assessment paragraphs (one per criterion), then a one-paragraph verdict: keep, cut, or restructure, with the single strongest reason.
