TeX-family judgment for source and generated artifacts, engines, document classes, packages, macros, bibliography, build convergence, diagnostics, and rendered output. Use only when producing or materially revising substantive TeX-family source whose TeX behavior matters. Do not activate for routine technical Q&A, repository browsing, read-only inspection, compiler or tool use, file types, fenced examples, rendered PDFs, project labels, or incidental TeX mentions.
