# 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.
