+## Co zrobiono
+
+- [Phase 129, Plan 01] Wdrozono mapowanie i synchronizacje statusow Erli w obu kierunkach: Erli -> orderPRO przez inbox oraz orderPRO -> Erli przez `PATCH /orders/{id}/status`.
+- Dodano tabele pull/push mapowan statusow Erli, seed statusow, kursor `last_status_pushed_at`, ustawienia `erli_status_sync_*` i cron `erli_status_sync`.
+- Dodano repozytoria mapowan, `ErliStatusSyncService`, `ErliStatusSyncHandler`, discovery nieznanych statusow Erli i testy jednostkowe dla mappera/status sync.
+- Ujednolicono `/settings/integrations/erli` z innymi integracjami przez zakladki Integracja, Statusy i Ustawienia.
+- Udokumentowano gapy srodowiskowe: brak `vendor/bin/phpunit`, globalny XAMPP PHPUnit niekompatybilny z PHP, brak `sonar-scanner` w PATH.
