Beamer Compile QA

Triggers & routing

• Trigger: beamer compile, slides compile, tutorial slides pdf, 编译幻灯片, beamer pdf.
• Use when: source-tutorial 的 C4，已有 latex/slides/main.tex，需要输出 latex/slides/main.pdf 和编译报告。
• Skip if: slides scaffold 还没完成。
• Network: none.
• Guardrail: 编译失败也要落盘可读报告，不能只返回报错。

Goal: compile the Beamer deck and record success or failure in a stable report.

The compiler should treat latex/slides/main.tex as the entrypoint and emit both latex/slides/main.pdf and output/SLIDES_BUILD_REPORT.md.

Inputs

• latex/slides/main.tex
