# Test Case: Shared xattr scan not found

**Test ID**: TC068-shared-xattr-scan-notfound
**Fixture**: `basic.erofs`, `/shared-a`

## Objective

Verify clean exhaustion of inline and shared scans and namespace isolation.

## Manual steps

Mount `basic.erofs`, list the user namespace, then capture both misses:

```sh
lsextattr user /mnt/repo22-g4/shared-a
truss -o /tmp/tc068-name.truss \
  getextattr -qq user nonexistent /mnt/repo22-g4/shared-a
truss -o /tmp/tc068-ns.truss \
  getextattr -qq system shared_key /mnt/repo22-g4/shared-a
grep extattr_get_file /tmp/tc068-*.truss
```

## Expected results

Both kernel calls return `ENOATTR` (87), with no `EINTEGRITY`, delay, or name
leak into the FreeBSD `system` namespace. Unmount and detach the image.
