# Test Case: Directory with dot_omitted

**Test ID**: TC026-dot-omitted-with

## Objective

Verify a bit-4 directory omits only `.` on disk, retains explicit `..`, and
receives a synthetic `.` from FreeBSD readdir.

## Fixture

Use `images/compact-dot-omitted.erofs`. Structured evidence records bit 4,
on-disk names `..,child.txt`, 48-bit incompat selection with nonzero
`rootnid_8b`, `blocks_hi=0`, and valid CRC. Production fsck.erofs 1.8.6 cannot
qualify this newer format.

## Procedure

After mounting in FreeBSD:

```sh
stat -f 'ino=%i nlink=%l mode=%p' "$mnt/dotdir"
ls -lai "$mnt/dotdir"
(cd "$mnt/dotdir" && test "$(pwd)" = "$mnt/dotdir")
cmp /tmp/repo22-g1/source/compact/dotdir/child.txt "$mnt/dotdir/child.txt"
```

## Expected Results

- User-visible listing contains both `.` and `..`; `.` has the directory NID.
- Structured evidence, not the listing, proves `.` is absent on disk and bit 4
  is set; `..` remains an on-disk entry.
- Child data, navigation, mount, and cleanup succeed.
