Missing pages

Missing slugs come from explicit frontmatter missing_prerequisites and from prose wikilinks that have no source page yet. Each one gets a stable static URL so the graph, validator, and contributors agree.

40 missing pages aggregated. Click any title for the static stub plus a GitHub page-request link.
