# Test Case: Prefix table lookup **Test ID**: TC080-prefix-table-lookup **Fixture**: `basic.erofs`, `/prefix-user-0` through `/prefix-user-3` ## Objective Verify repeated prefix-ID lookup and a clean missing-suffix result. ## Manual steps Run the following lookup separately for suffix files 0, 1, 2, and 3: ```sh getextattr -qq -x user repo22.application.component.setting \ /mnt/repo22-g4/prefix-user-N truss -o /tmp/tc080.truss getextattr -qq user \ repo22.application.component.missing /mnt/repo22-g4/prefix-user-0 grep extattr_get_file /tmp/tc080.truss ``` ## Expected results Values are `prefix-value-N` for each file; the missing suffix is `ENOATTR` (87), not an integrity failure. Unmount and detach.
