Tutorial Self-Loop

Triggers & routing

• Trigger: tutorial self-loop, tutorial quality gate, tutorial pass/fail, 教程自循环, 教程质量门.
• Use when: source-tutorial 的 C3，已经有 output/TUTORIAL.md，想在交付前确认它满足教程合同而不是普通长文。
• Skip if: 还没有 tutorial 正文。
• Network: none.
• Guardrail: 报告缺口时不要发明内容；把失败清楚地路由回 tutorial 写作阶段。

Goal: converge the tutorial deliverable to a stable teaching-quality bar.

The gate should compare output/TUTORIAL.md against the intended module shape from outline/module_plan.yml, rather than acting like a generic prose checker.

Inputs

• output/TUTORIAL.md
• outline/module_plan.yml
