+# Test Case: Shared xattr scan found
+
+**Test ID**: TC067-shared-xattr-scan-found
+**Fixture**: `basic.erofs`, `/shared-a`, `/shared-b`
+
+## Objective
+
+Verify that shared IDs are scanned after inline entries and return exact data.
+The generator manifest must show `shared_key` in the shared table and `local`
+inline on `/shared-a`.
+
+## Manual steps
+
+Mount `basic.erofs` using `G4-MANUAL-SETUP.md`, then run:
+
+```sh
+lsextattr user /mnt/repo22-g4/shared-a
+getextattr -qq -x user shared_key /mnt/repo22-g4/shared-a
+getextattr -qq -x user shared_key /mnt/repo22-g4/shared-b
+getextattr -qq -x user local /mnt/repo22-g4/shared-a
+stat -f 'size=%z inode=%i' /mnt/repo22-g4/shared-a
+```
+
+## Expected results
+
+Both shared reads equal `shared-value\0exact` byte-for-byte, the inline read is
+`in-bounds-local`, and list output contains all four expected user names.
+Unmount and detach before the next TC.
