Laravel评论权限政策失效修复求助（Inertia JS环境）

我用Inertia JS搭建了一个支持帖子和评论CRUD操作的论坛，设定仅内容创作者及管理员可修改/删除对应内容。目前帖子权限政策已正常生效，但评论权限政策无法工作，请求协助修复。

相关代码 #

帖子与评论的show方法 #

public function show(Post $post, Comment $comment)
{
    usleep(500000);

    $post->incrementReadCount();

    $updateableCommentIds = $post->comments
        ->map(function ($comment) {
            if (Auth::user()->can('update', $comment)) {
                return $comment->id;
            }
        })
        ->filter();

    return Inertia::render('Frontend/Forum/Helpers/PostDetails', [
        'post' => PostResource::make(
            $post->load('user')->loadCount('comments')
        ),
        'comments' => CommentResource::collection(
            Comment::where('post_id', $post->id)
                ->with('user')
                ->paginate(10)
                ->withQueryString()
        ),
        'categories' => Category::all(),
        'can' => [
            'edit' => Auth::check() && Auth::user()->can('edit', $post),
            'commentEdit' => $updateableCommentIds
        ]
    ]);
}

评论权限政策 #

class CommentPolicy
{
    use HandlesAuthorization;

    public function update(User $user, Comment $comment): bool
    {
        return $user->is_admin || $user->id === (int) $comment->user_id;
    }
}

Vue文件相关代码 #

<div
v-if="can.commentEdit.includes(comment.id)"
>
        // 仅评论作者可见的操作区域
</div>

已尝试的修改（无效） #

public function show(Post $post)
{
    $canUpdateComments = $post->comments->every(function ($comment) {
        return Auth::user()->can('update', $comment);
    });

    // 返回视图并传递评论修改权限
    return view('posts.show', compact('post', 'canUpdateComments'));
}
