# Test Case: Dot Entry Handling

**Test ID**: TC049-dot-handling
**Category**: Directory Operations
**Priority**: High

## Objective

Verify dot is returned as a directory entry and explicit dot lookup resolves
to the same vnode as its directory.

## Procedure

Mount vfs/vfs-plain.erofs and run:

    ./readdir_probe /tmp/repo22-g3/mnt/testdir 128
    stat -f '%i %HT' /tmp/repo22-g3/mnt/testdir
    stat -f '%i %HT' /tmp/repo22-g3/mnt/testdir/.
    cmp fixtures/vfs/source/testdir/file.txt \
      /tmp/repo22-g3/mnt/./testdir/./file.txt

## Expected Results

The traversal includes one dot entry with DT_DIR, both stat commands report
the same directory NID, and paths containing dot read source-exact data.
Record output and cleanup.
