# 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.
