Summarise a Long Email Thread Into a Briefing Note

A forty-email thread about a project decision is not a document anyone should have to read in full. The decisions, actions, and unresolved questions are in there somewhere and this extracts them. Paste the thread and get a briefing note that tells you what was decided, what is outstanding, and what is still being argued about.
