Test Case: Lookup - Missing Entry

Test ID: TC044-lookup-not-found Category: Directory Operations Priority: High

Objective

Verify direct missing lookups return exact ENOENT without masking existing entries or turning other errors into a miss.

Procedure

Mount vfs/vfs-plain.erofs and run:

./g3_vfs_probe expect-error stat \
  /tmp/repo22-g3/mnt/testdir/nonexistent.txt 2
./g3_vfs_probe expect-error stat \
  /tmp/repo22-g3/mnt/testdir/nonexistent.txt 2
./g3_vfs_probe expect-error stat \
  /tmp/repo22-g3/mnt/no-such-directory/file.txt 2
./g3_vfs_probe expect-success stat \
  /tmp/repo22-g3/mnt/testdir/file.txt

Expected Results

Each missing syscall reports errno 2 and the positive control succeeds. Wrapper text alone is not evidence; record the helper output and cleanup.
