Workflow

1. Normalize topic, audience, outcome, language, formats, user material, style references, and exclusions into brief.json.
2. Read references/input-adaptation.md; use user material as the spine when sufficient, then add only needed external research.
3. Read references/research-sourcing.md; create research/user-materials-register.md when needed, research/source-register.md, and research/evidence-map.md.
4. Read references/tutorial-outline-and-writing.md plus references/course-design-principles.md; write outline.md, standalone public tutorial.md using 第1章 and 1.1, and research/chapter-quality-review.md.
5. Read the editorial and visual references; create visuals/visual-spec.json, then run build_visual_pack.py and capture_visuals.py.
6. Read references/export-workflow.md; run export_tutorial.py and then validate_package.py.
7. Report exact failures and fallbacks. Never fabricate X posts, papers, repo details, dates, or citations.
