Summarise A Long Neighbour Dispute Email Chain

Six weeks of emails about a fence or a hedge and you have lost track of who promised what. This pulls the whole thread into what each side wanted, where you actually still disagree, and the one question still blocking things, so you can decide what to do next without rereading everything.

<context>
You have an email thread with a neighbour about {DISPUTE_TOPIC} that has gone back and forth for weeks and is now too long to keep track of.
</context>

<task>
**Summarise the thread:**
1. What each side originally wanted, in one line each
2. Where the two positions actually differ now versus where they already agree
3. Any promises or deadlines either side has made in writing
4. The single open question that is blocking a resolution
