Coverage for src\genesis\writer\template_mapper.py: 95%

1"""模板 → 有序章节规格映射（Phase 5）。 

2 

3真实 ParsedTemplate.sections 为 ChapterMarker 列表；章节由 type=="heading" 起， 

4紧随其后的 type=="placeholder" 且形如 `section:<id>` 的标记归属该章， 

5用于确定 chapter_id 与 section_placeholder（语言无关、按文档顺序）。 

6 

7design.md §6.5 映射规则：仅 Heading level<=1 起章（1 章 = 1 次生成循环）； 

8level>=2 的节/小节归入当前章 sub_headings，随本章一并生成——避免无 

9{{section:id}} 锚点的子章「生成后静默丢弃」。
