# Test Case: chown Rejection

**Test ID**: TC062-setattr-chown-reject
**Category**: Read-Only Enforcement
**Priority**: Critical

## Objective

Verify a privileged direct chown request returns EROFS and leaves ownership
unchanged.

## Procedure

Mount vfs/vfs-plain.erofs as root and run:

    ./g3_vfs_probe stat /tmp/repo22-g3/mnt/testdir/file.txt > TC062-before.txt
    ./g3_vfs_probe expect-error chown \
      /tmp/repo22-g3/mnt/testdir/file.txt 30
    ./g3_vfs_probe stat /tmp/repo22-g3/mnt/testdir/file.txt > TC062-after.txt
    cmp TC062-before.txt TC062-after.txt

## Expected Results

chown to uid/gid 65534 reports errno 30 and metadata remains unchanged. Record
output and cleanup.
