How to chain ChatGPT calls for multi-source synthesis
I want a reproducible pattern to ingest PDFs, extract key points, then synthesize with evidence links. Looking for step-by-step chaining and prompt templates.

4-step chain:
1) Split PDF into ~1,500–2,000-token chunks; name each chunk file.pdf#p1-3.
2) Per-chunk prompt: 'Extract 6 key points as bullets. For each, include a 1-sentence evidence snippet and source tag [file.pdf#p1-3].'
3) Consolidation prompt: 'Merge all bullets, dedupe, group by theme, keep source tags, and rank top 10 by relevance.'
4) Synthesis prompt: 'Produce a 300–400 word summary with inline citations (file.pdf#p1) and an evidence table mapping claims→source tags.'
