# Part IV — clean source upload Upload this folder's contents as one independent submission. Select `main.tex` as the main file and pdfLaTeX as the compiler. No companion source folder, BibTeX run, Python script, or shell escape is required. To compile locally: ```sh latexmk -pdf main.tex ``` This folder contains Sections 24–30, the shared front matter, style and warning image, the complete bibliography, and frozen companion reference data. The mathematical body matches repository commit `def7355` exactly. The authors' note changes only the volume count from three to five. `references.tex` supplies the complete fixed bibliography to preserve the same citation numbers across the five submissions. `refs.bib` is the editable bibliographic database. `cross-volume-labels.tex` supplies the other parts' theorem, section, equation, and page references without requiring their build products. These two `.tex` files are required inputs. For a locally compiled PDF, use the filename `3d-ym-torus-volume-iv.pdf`. Cross-PDF links retain these existing companion filenames. Keep downloaded companion PDFs together under those names. If Hexagon assigns different hosted PDF URLs, their targets can be updated in `cross-volume-labels.tex` once those URLs are available. No PDFs, audit reports, research notes, build logs, auxiliary files, or other parts' body sections are included in this upload. When the shared manuscript changes, regenerate the five packages together so their frozen reference data stay synchronized.
