+# 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.
