# Test Case: Packed prefix table

**Test ID**: TC079-packed-prefix-table
**Fixture**: `basic.erofs`

## Objective

Verify a non-plain prefix table carried by the packed inode generated by
erofs-utils 1.8.6.

## Layout qualification

```sh
dump.erofs -s "$run/images/basic.erofs"
python3 tests/g4_fixtures.py verify --output "$run"
```

Require `xattr_prefix_count=2`, nonzero `packed_nid`, prefix start 0, user
record `(base=1, infix=repo22.application.component.)`, trusted record
`(base=4, infix=repo22.trusted.deep.)`, and matching image hash.

## Guest observations

```sh
getextattr -qq -x user repo22.application.component.setting \
  /mnt/repo22-g4/prefix-user-2
getextattr -qq -x system trusted.repo22.trusted.deep.setting \
  /mnt/repo22-g4/prefix-trusted-2
stat -f 'mode=%Sp inode=%i' /mnt/repo22-g4/prefix-user-2 \
  /mnt/repo22-g4/prefix-trusted-2
```

Both values must end in `-2`; cleanup must be empty.
