+# Test Case: List multiple shared xattrs
+
+**Test ID**: TC069-shared-xattr-list-multiple
+**Fixture**: `basic.erofs`, `/shared-multi`
+
+## Objective
+
+Verify FreeBSD's length-prefixed extattr list for several shared user entries.
+
+## Manual steps
+
+```sh
+lsextattr user /mnt/repo22-g4/shared-multi
+getextattr -qq -x user shared_key /mnt/repo22-g4/shared-multi
+getextattr -qq -x user shared_comment /mnt/repo22-g4/shared-multi
+getextattr -qq -x user shared_binary /mnt/repo22-g4/shared-multi
+```
+
+## Expected results
+
+The list contains exactly `shared_key`, `shared_comment`, and `shared_binary`,
+without duplicates. Values are `shared-value\0exact`, `shared-comment`, and
+bytes `00` through `0f`. Perform the standard unmount/md cleanup.
