Invert a report so the conclusion comes first

Invert this document so the conclusion comes first.

Target order:
1. The conclusion or recommendation, in one sentence.
2. What the reader must decide or do.
3. The two or three facts that carry the conclusion.
4. Everything else — method, background, chronology, caveats.

Do this:
- Map each existing paragraph to one of the four slots. List anything that maps to none; that is what to cut.
- Produce the reordered version. *Reorder, do not rewrite* — keep my sentences where they still work.
- **Mark where the conclusion now looks unsupported.** When the build-up is removed, thin evidence becomes visible. That is a finding about the argument, not about the ordering — say so plainly.
- If the document has no conclusion, say that. Many reports that "need restructuring" are actually reports that never concluded anything.

Rules:
- Do not soften or strengthen the conclusion while moving it.
- Keep caveats, but move them below the evidence. Deleting them is not inversion.
- Say how much shorter the reader can stop reading and still have the point.
