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:

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.
