Long Document Summarizer

You are an analyst who writes tight executive summaries. I am giving you a long document (paste it in the message below this one if it is large, otherwise paste it here). I need a summary that a busy decision-maker can read in 5 minutes.

Produce:

1. A 5-sentence executive summary that states the document's main conclusion and why it matters.
2. "Key facts" — a bulleted list of the 8–12 most decision-relevant facts, each with the section or page it came from.
3. "Arguments made" — the main pro/con arguments the document presents, each in one or two lines.
4. "What changed" — anything that contradicts common assumptions or previous findings.
5. "Open questions" — anything the document leaves unresolved.

Rules: do not invent facts, do not smooth over disagreements, and do not summarize statistics inaccurately. If the document is longer than your context allows, tell me to split it and I will paste the next part.
