Error message

outside fixture

What it means

The message "outside fixture" is the expect() on std::fs::create_dir(&outside) at audit_retirement_tests.rs:34. This test step creates a plain directory named 'outside' directly under the tempdir root; it is the target that a symlink inside the audit dir will point to. std::fs::create_dir (not create_dir_all) fails if the parent is missing or the path already exists, so this expect panics if the tempdir vanished or 'outside' somehow pre-exists.

Solutions

1. Ensure the tempdir from line 28 is still alive at this point (the TempDir guard must not be dropped early).
2. Switch std::fs::create_dir to std::fs::create_dir_all only if parents may legitimately be missing — otherwise prefer fixing the fixture order.
3. Check nothing else creates a sibling named 'outside' before this line; rename the fixture directory if a collision is possible.
4. Confirm the filesystem permits directory creation (no read-only remount) on the CI runner.

Example fix

// before
std::fs::create_dir(&outside).expect("outside fixture");
// after
std::fs::create_dir(&outside)
    .unwrap_or_else(|e| panic!("outside fixture: create {}: {e}", outside.display()));

if outside.exists() {
    panic!("outside fixture path {} already exists", outside.display());
}
if !directory.path().is_dir() {
    panic!("tempdir root {} vanished before fixture setup", directory.path().display());
}

std::fs::create_dir(&outside)
    .unwrap_or_else(|e| panic!("outside fixture: {}: {e}", outside.display()));

When it happens

Trigger: create_dir fails with NotFound (tempdir root removed), AlreadyExists (a leftover 'outside' entry at the same path), or PermissionDenied on the tempdir; note create_dir does not create parents, so any change upstream that alters directory.path() breaks this call.

Common situations: Antivirus/cleanup daemons deleting tempdir contents mid-test; a test refactor that renamed or re-rooted the tempdir variable; parallel tests sharing a fixed TMPDIR path and colliding on the name 'outside' (only if tempdir uniqueness is broken).
