# LaTeX repair Stage 07's gate wants `workspace/writing/main.tex`, section files, a bibliography, a compiled PDF, and `workspace/artifacts/build_log.txt`. When the build fails, the loop to avoid is: change something, recompile, read the same error, change something else. LaTeX reports the *first* thing that broke, and one real cause usually generates a cascade of downstream errors. ## Triage order Read `build_log.txt` from the top and fix in this order. Recompile after each class, not after each edit. 1. **Missing style package** — `LaTeX Error: File 'neurips_2025.sty' not found`. AutoR does not vendor official style files (`templates/registry.yaml` says so and carries the venue's `official_url`). Either fetch the style package to `workspace/writing/`, or fall back to a standard class and record the substitution honestly in the stage summary. Do **not** silently switch venue. 2. **Undefined control sequence** — a command from a package that is not loaded, or a typo. Check the preamble before assuming the command is wrong. 3. **Missing `$` / runaway argument** — almost always an unescaped `_`, `%`, `&` or `#` in prose that came from a variable name or a file path. These are common when text was assembled from JSON results. 4. **Undefined references and citations** — `LaTeX Warning: Citation 'x' undefined`. Requires a bibtex/biber pass and then two more LaTeX passes. A single compile will always report these. 5. **Overfull boxes and float drift** ...
