check is_file/is_readable before hashing), leaving $linkCount defaulted and
$hashValid false when stat/hash_file fail to avoid runtime warnings and

Move per-row file I/O + hashing out of the Blade view.
file_exists, stat, and especially hash_file per document will scale poorly on list pages and can noticeably slow requests when documents or files are large. Consider precomputing these values in the controller/service (or caching them) and passing them into the view.

Guard stat/hash_file failures to avoid runtime warnings.
file_exists is a TOCTOU check; the file can disappear between checks, causing stat/hash_file warnings and inconsistent state. Add a defensive guard and only mark hash valid when computation succeeds.
✅ Suggested guard
- if ($fileExists) {
- $stats = stat($filePath);
- $linkCount = $stats['nlink'] ?? 0;
- $hashValid = ($doc->hash === hash_file('sha256', $filePath));

In `@app/Http/Controllers/DocumentController.php`:
- Around line 284-285: stat($filePath) can return false if the file is removed
between file_exists() and stat() (TOCTOU); update the block in
DocumentController (around the $stats = stat($filePath) and $doc->link_count
assignment) to check that $stats !== false (or is_array($stats)) before
accessing $stats['nlink'], and fall back to 0 when stat() failed so
$doc->link_count is always safely assigned.
In `@resources/views/documents/check.blade.php`:
- Around line 14-15: Replace the hardcoded column headers "Links" and "Status"
in the Blade view with translation helpers (e.g. use
trans('cruds.document.fields.links') and trans('cruds.document.fields.status')
or `@lang`(...) in the same locations), and add the corresponding keys ("links"
and "status") under cruds.document.fields in your language files so the labels
render correctly for localized deployments.

274-292: Consider pagination or lazy loading for large document sets.
Document::all()loads the entire table into memory, and each document triggers disk I/O (stat,hash_file). For admin-only diagnostic pages this is acceptable, but if the document count grows significantly, consider adding pagination or a cursor-based approach.

Guard stat() return value before array access.
If the file is deleted between the file_exists() check and stat() call (TOCTOU race), stat() returns false. Accessing $stats['nlink'] on false will produce a PHP warning.

$stats = stat($filePath);

Add translation keys for new column headers.
Other column headers use trans('cruds.document.fields.xxx') for internationalization, but "Links" and "Status" are hardcoded English strings. This breaks consistency for localized deployments.
🌐 Proposed fix
- <th>Links</th>
- <th>Status</th>
+ <th>{{ trans('cruds.document.fields.links') }}</th>
+ <th>{{ trans('cruds.document.fields.status') }}</th>Don't forget to add the corresponding keys to your language files.

- Around line 283-290: The code calls hash_equals($doc->hash, $computedHash)
without ensuring $doc->hash is a string; update the DocumentController logic so
you only call hash_equals when $doc->hash is a non-null string (e.g.,
is_string($doc->hash) && $doc->hash !== '') or otherwise set $doc->hash_valid to
false (or compare using a safe cast) — change the block around $computedHash and
$doc->hash_valid in the DocumentController to guard $doc->hash before calling
hash_equals and ensure $doc->hash_valid is deterministically set when
legacy/null hashes are present.
