# Test Case: Directory Entry Decoding - Multi-Block Directory

**Test ID**: TC042-dirent-large-dir
**Category**: Directory Operations
**Priority**: High

## Objective

Decode a real multi-block directory without missing, duplicating, or
truncating entries across directory-block boundaries.

## Procedure

Mount metadata/namei-base.erofs and run:

    ./readdir_probe /tmp/repo22-g3/mnt/wide 128
    find /tmp/repo22-g3/mnt/wide -maxdepth 1 -type f |
      sed 's#.*/##' | sort > actual-wide.txt
    cmp fixtures/metadata/expected-wide.txt actual-wide.txt
    stat /tmp/repo22-g3/mnt/wide/entry-000-abcdefghijklmnopqrstuvwxyz.txt
    stat /tmp/repo22-g3/mnt/wide/entry-159-abcdefghijklmnopqrstuvwxyz.txt
    stat /tmp/repo22-g3/mnt/wide/entry-319-abcdefghijklmnopqrstuvwxyz.txt

## Expected Results

All 320 real files plus dot and dotdot are returned once. The helper reports
322 restartable kernel and libc positions and the three boundary samples stat
successfully. Record the image hash and cleanup.
