# Test Case: Nonzero Directory Tail Padding

**Test ID**: TC148-linux-directory-tail-padding
**Category**: Directory Compatibility
**Priority**: Critical

## Objective

Verify FreeBSD accepts the structured eight-byte PAD!ERO! patch after the final
directory-name NUL and still returns complete names and restartable cookies.

## Procedure

Record metadata/fixture-evidence.txt and the
metadata/namei-padding-nonzero.erofs hash. On a fresh mount:

    printf 'wide entry 079\n' > expected-079.txt
    cmp expected-079.txt \
      /tmp/repo22-g3/mnt/wide/entry-079-abcdefghijklmnopqrstuvwxyz.txt
    test "$(find /tmp/repo22-g3/mnt/wide -maxdepth 1 -type f |
      wc -l)" -eq 320
    ./readdir_probe /tmp/repo22-g3/mnt/wide 128

## Expected Results

The actual patched image mounts, reads exact data, exposes 320 real files, and
reports 322 valid kernel/libc restart positions. Userspace fixture inspection
alone is not PASS. Record image/evidence hashes and cleanup.
