Section Merger

Triggers & routing

• Trigger: merge sections, merge draft, combine section files, sections/ -> output/DRAFT.md, 合并小节, 拼接草稿.
• Use when: you have per-unit prose files under sections/ and want a single output/DRAFT.md for polishing/review/LaTeX.

Goal: assemble a paper-like output/DRAFT.md from:

• sections/ (per-section/per-subsection prose)
• outline/transitions.md (optional hand-off suggestions; generated by transition-weaver)
• outline/tables_appendix.md (reader-facing Appendix tables; generated by appendix-table-writer)

Merge order is driven by outline/outline.yml. The draft title is derived from GOAL.md when present. When sections/sections_manifest.jsonl is supplied by the Pipeline contract, every merged section must match its recorded bytes and SHA-256 hash.

This skill is deterministic: it does not rewrite content or invent prose; it only merges already-generated artifacts.
