+# 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.
