+# Test Case: Lookup - Existing Entries
+
+**Test ID**: TC043-lookup-found
+**Category**: Directory Operations
+**Priority**: Critical
+
+## Objective
+
+Verify exact-name lookup of regular, directory, and symlink entries returns
+stable vnode metadata and source-exact data.
+
+## Procedure
+
+Mount vfs/vfs-plain.erofs and run:
+
+    ./g3_vfs_probe stat /tmp/repo22-g3/mnt/testdir/file.txt
+    ./g3_vfs_probe stat /tmp/repo22-g3/mnt/testdir/subdir
+    ./g3_vfs_probe stat /tmp/repo22-g3/mnt/testdir/shortlink
+    ./g3_vfs_probe stat /tmp/repo22-g3/mnt/testdir/file.txt
+    cmp fixtures/vfs/source/testdir/file.txt \
+      /tmp/repo22-g3/mnt/testdir/file.txt
+    sha256 fixtures/vfs/source/testdir/file.txt \
+      /tmp/repo22-g3/mnt/testdir/file.txt
+
+## Expected Results
+
+All lookups succeed, repeated file lookup reports the same nonzero inode, each
+type/mode/size matches fixture evidence, and source/mounted hashes are equal.
+Record command statuses and cleanup.
