+# Message Queue — 实现细节
+
+> 主流程见 SKILL.md，本文档为配置、Job、投递、事件驱动、监控的完整代码。
+
+## 队列配置
+
+```php
+// config/autoload/async_queue.php
+return [
+    'default' => [
+        'driver' => Hyperf\AsyncQueue\Driver\RedisDriver::class,
+        'redis' => ['pool' => 'default'],
+        'channel' => env('QUEUE_CHANNEL', '{queue}'),
+        'timeout' => 2,
+        'retry_seconds' => [1, 5, 10, 30, 60],
+        'handle_timeout' => 60,
+        'processes' => 1,
+        'concurrent' => ['limit' => 10],
+    ],
+    'notification' => [ /* 独立队列，更高优先级 */ ],
+];
+```
+
+## Job 类模板
+
+```php
+class {{JobName}}Job extends Job
+{
+    protected int $maxAttempts = 3;
+    public function __construct(protected readonly int $resourceId, protected readonly array $payload = []) {}
+    public function handle(): void {
+        $resource = $this->getResource();
+        if (!$resource || $this->isAlreadyProcessed($resource)) return;
+        try { $this->process($resource); }
+        catch (\Throwable $e) { logger()->error(...); throw $e; }
+    }
+}
+```
+
+## 投递与事件驱动
+
+QueueService：`dispatch($job, $delay)`、`dispatchNotification($job)`、`dispatchDelayed($job, $delaySeconds)`。事件驱动：Event → Listener → QueueService->dispatch。示例：OrderStatusChanged → 异步通知、同步外部、更新统计缓存（debounce 5s）。
+
+## 监控命令
+
+Redis `{queue}:waiting`、`{queue}:delayed`、`{queue}:failed`、`{queue}:timeout`。failed > 100 告警。
