Broken link checker

Check every link in a docs set, internal and external, and explain how to fix each failure without changing link intent.

Status

Scaffold only — not ready for use.

Planned

• Resolve relative Markdown links and heading anchors against the repo
• Check external URLs with polite rate limits and report 4xx, 5xx, timeouts, and redirect chains
• Flag links that point at unstable targets, such as editor or preview URLs
• Suggest the most likely correct target for each broken link
• Output a report grouped by page and severity
