# Test Case: Broken Symlink

**Test ID**: TC040-symlink-broken

## Objective

Verify `readlink(2)` succeeds for a deterministic broken link while following
the target fails with exact `ENOENT`.

## Fixture

Use `images/inline.erofs` and `source/inline/brokenlink`. Evidence asserts
symlink mode, layout 2, and target length 29.

## Procedure

```sh
test -L "$mnt/brokenlink"
readlink /tmp/repo22-g1/source/inline/brokenlink > /tmp/tc040-source-target
readlink "$mnt/brokenlink" > /tmp/tc040-mount-target
cmp /tmp/tc040-source-target /tmp/tc040-mount-target
./read_probe expect-error "$mnt/brokenlink" 2
./read_probe expect-error "$mnt/brokenlink" 2
```

## Expected Results

- Both `readlink` targets equal `/nonexistent/repo22-g1-target`.
- Both follow attempts return errno 2 (`ENOENT`), while the symlink itself
  remains visible; no kernel error or cleanup failure occurs.
