From e9f26869d80a14c2491de238777515efced6c6f9 Mon Sep 17 00:00:00 2001 From: Array Fleet Date: Tue, 30 Jun 2026 15:04:52 +0000 Subject: [PATCH 01/11] feat(janitor): external link rot detection with HTTP probes and cache Closes #423. Opt-in janitor rule scans markdown bodies for external URLs, rate-limits HEAD/GET checks, caches results, and reports broken links in external_links and issue results.
