+# Broken Symlink Detection
+
+## Problem
+
+Library migrations may leave symbolic links pointing to files or folders that no
+longer exist. The filesystem scanner previously skipped those links silently.
+
+## Architecture
+
+One read-only filesystem traversal now returns audio tracks and broken symbolic
+links. Each finding preserves the link path and its raw target when the operating
+system can read it. The library and health report retain only immutable findings.
+
+Broken links are reported separately and do not affect the reference-integrity
+score. The detector does not follow, recreate, remove, or rewrite any link.
+
+## Edge Cases
+
+- Relative and absolute link targets.
+- Links to missing files and missing directories.
+- Link targets that cannot be read due to an operating-system error.
+- Valid symlinks, which remain eligible for ordinary audio scanning.
+
+## Verification
+
+Tests create synthetic valid and broken links in temporary directories, verify the
+raw target, and confirm health integration. Existing scanner behavior is preserved.
