# Test Case: getattr Basic Metadata

**Test ID**: TC055-getattr-basic
**Category**: Vnode Operations
**Priority**: Critical

## Objective

Verify VOP_GETATTR returns fixture-exact type, mode, ownership, link count,
size, allocation, block size, inode, and generation for plain and compressed
regular files.

## Procedure

On separate fresh mounts of vfs/vfs-plain.erofs and vfs/vfs-lz4.erofs:

    ./g3_vfs_probe stat /tmp/repo22-g3/mnt/pager.bin
    stat -f 'ino=%i mode=%p uid=%u gid=%g nlink=%l size=%z blocks=%b blksize=%k gen=%v type=%HT' \
      /tmp/repo22-g3/mnt/pager.bin
    sha256 /tmp/repo22-g3/mnt/pager.bin

For the plain mount also compare the mounted hash with
fixtures/vfs/source/pager.bin and fixture evidence.

## Expected Results

Both files are regular mode 0644, uid/gid 0, size 21211, block size 4096, with
nonzero stable NID/generation. Both logical hashes equal the source hash;
st_blocks records each inode's reported allocated sectors. Record both image
hashes and per-mount cleanup.
