Synthesize multiple sources into a decision-ready brief

Synthesize the following sources into a decision-ready brief. Sources: [PASTE EXCERPTS, NOTES, OR SUMMARIES, LABELED SOURCE 1, SOURCE 2, ETC.]. The question I am trying to answer: [YOUR RESEARCH QUESTION]. Audience for the brief: [WHO WILL READ IT]. Structure the output as follows. 1) Bottom line — the best-supported answer to my question in three sentences or fewer. 2) Points of agreement — claims supported by two or more sources, each tagged with the supporting sources, like (S1, S3). 3) Points of conflict — where sources disagree, presented as Source X says X, Source Y says Y, followed by one sentence on the most likely reason for the disagreement: different data, different definitions, different time periods, or different incentives. 4) Single-source claims — notable claims made by only one source, explicitly flagged as unverified. 5) Gaps — what my question needs that none of the sources cover. Rules: every claim in sections 2 through 4 must carry a source tag; never blend two sources into one untagged sentence; if a source is an opinion piece or vendor material rather than primary research, note that beside its first tag; do not add facts from outside the provided sources — if you know something relevant they omit, put it in a clearly separated note at the end labeled as outside the sources. Keep the brief under [WORD LIMIT] words.
