Section Mapper

Triggers & routing

• Trigger: section mapper, mapping.tsv, coverage, paper-to-section mapping, 论文映射, 覆盖率.
• Use when: structure 阶段（C2），已有 papers/core_set.csv + outline/outline.yml，需要确保每小节有足够支持论文再进入 evidence/writing。

Create a paper→subsection map that supports evidence building and later synthesis.

Good mapping is relevant, diverse, and explainable. Corpus-wide topic words and repeated outline boilerplate are not evidence of subsection relevance.

When to use

• You have outline/outline.yml and a papers/core_set.csv and need coverage per subsection.
• You want to identify weak-signal subsections early (so you can adjust scope or add papers).
