Why Are Laravel Horizon Silenced Jobs Persisting in Redis for 7 Days?

I've noticed that a batch of silenced jobs (~7k per hour) that complete successfully are not being cleared as expected. Regular completed jobs are trimmed after 1 hour, but these silenced jobs remain in Redis for 7 days, consuming a lot of space. I suspect they might be treated as monitored jobs in Horizon, which default to a 7-day trim time.

Below is my Horizon configuration for job trimming:

PHPCopied
/*
    |---------------------------------------------------------------------------------------------------|
    | Job Trimming Times                                                                                |
    |---------------------------------------------------------------------------------------------------|
    |                                                                                                |
    | Here you can configure for how long (in minutes) you desire Horizon to                           |
    | persist the recent and failed jobs. Typically, recent jobs are kept                               |
    | for one hour while all failed jobs are stored for an entire week.                                 |
    |                                                                                                |
    */

    'trim' => [
        'recent' => 60,
        'pending' => 60,
        'completed' => 60,
        'recent_failed' => 10080,
        'failed' => 10080,
        'monitored' => 10080,
    ],

Here is the job implementation:

PHPCopied
class ClearCategorySkusJob implements ShouldBeUnique, ShouldQueue, Silenced {
    use Dispatchable, Queueable;

    public int $tries = 3;

    public function __construct(
        private readonly string $category,
        private readonly string $domain,
    ) {
        $this->onQueue('cache');
    }

    public function handle(): void {}
    
    public function uniqueId(): string {}

    public function tags(): array {}

}

Environment details:

• PHP version: 8.2.26
• Redis version: 6.2.13
• Laravel version: 10.48.24
• Horizon version: 5.24.3

I would like to have these silenced (monitored) jobs trimmed sooner (matching the 60-minute setting for completed jobs). How can I adjust their trim time or change their default behavior?
