# Test Case: Root Vnode Lookup

**Test ID**: TC011-root-vnode

## Objective

Verify the mounted root vnode has the encoded root NID, directory attributes,
and the same top-level names as the fixture source.

## Fixture

Use `images/compact.erofs` and `source/compact`. The structured evidence records
the root NID and compact inode size. Follow `tests/G1-MANUAL-SETUP.md`.

## Procedure

After mounting on `$mnt`:

```sh
stat -f 'ino=%i type=%HT mode=%Lp nlink=%l' "$mnt"
stat -f '%i' "$mnt" > /tmp/tc011-root-nid
ls -la "$mnt"
(cd /tmp/repo22-g1/source/compact && ls -1A | sort) > /tmp/tc011-source-names
(cd "$mnt" && ls -1A | sort) > /tmp/tc011-mount-names
diff -u /tmp/tc011-source-names /tmp/tc011-mount-names
cat "$mnt/root.txt"
```

Compare `/tmp/tc011-root-nid` with `root_nid` from `fixture-evidence.txt`, then
unmount, detach, and remove the two temporary name lists.

## Expected Results

- Root inode equals the encoded NID and reports a traversable directory.
- The complete top-level name lists match and `root.txt` is readable.
- All operations and cleanup return zero.
