+### Log Retention
+
+Logs are pruned automatically based on the `log_retention_days` setting (see [Site Settings](#) — `GET`/`PATCH /api/v1/admin/settings`, whitelisted key `log_retention_days`, default `90`, `0` = keep forever).
+
+- A daily scheduled task (`App\Shared\Logging\Message\PruneLogsMessage`, registered in `src/Schedule.php`, routed to `scheduler_default`) deletes logs older than `log_retention_days`.
+- Manual prune: `php bin/console app:prune-logs` (reads the same setting, deletes older-than-retention rows, prints the count).
+- Requires the scheduler worker: `php bin/console messenger:consume scheduler_default`.
