I ran a link check over docs/ (845 unique URLs) and three links to our own site are dead:
docs/source/user-guide/concepts-readings-events.md links two blog posts under slugs that were never published:
blog/2026/03/20/multi-layer-pruning/ is published at blog/2026/03/20/limit-pruning/blog/2026/02/02/case-expression/ is published at blog/2026/02/02/datafusion_case/
docs/source/contributor-guide/gsoc/gsoc_project_ideas_2025.md links contributor-guide/gsoc_application_guidelines.html, which is one directory too high and missing the year suffix. The page is at contributor-guide/gsoc/gsoc_application_guidelines_2025.html.
All three replacements return 200; all three current URLs return 404.
Three more are dead but the right target is a judgement call, so I left them alone: the four synnada.ai blog posts in concepts-readings-events.md (that blog is gone entirely), the datacouncil.ai talk link in the same file, and the MSEdge VirtualBox image at az792536.vo.msecnd.net in contributor-guide/development_environment.md, which Microsoft stopped serving. Happy to fix any of those too if you say what you want them to point at.
Disclosure: found and verified with AI assistance (Claude, via Claude Code). Every URL above was checked with a request rather than inferred.
