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:

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.
