  25. 25.research-proposal

The literature-corpus half of 开题报告 (exhaustive, reproducible retrieval with recall evidence) belongs to the lit-search skill; this skill consumes its outputs (dois.md / references.md — the default formatted list; references.bib only when lit-search ran with --bibtex). Not for backward-looking literature reviews / 综述 / surveys (use medical-imaging-review). For grant applications (国自然/NSF) it drafts and structures the CONTENT (立项依据/研究内容/…) but never fills a funder's own form system or budget tables.
