## Accumulated Context

### Decisions
- Use existing `CouponRepository::markAsUsed()` instead of adding methods to stdClass
- 2026-03-16: Przyczyna braku wysyłki = brakujące $apiloRepository w use() closures cron.php (regresja z fazy 6)
- 2026-03-16: Retry -1 orders co 1h zamiast permanent failure
- 2026-03-16: Email notification o trwale failed Apilo jobach
- 2026-03-19: Order-related Apilo joby — infinite retry co 30 min (nigdy permanent failure)
- 2026-03-19: Email z danymi zamówienia + rozróżnienie PONAWIANY vs TRWAŁY BŁĄD
- 2026-03-19: Cleanup stuck sync_payment/sync_status jobów po udanym wysłaniu
- 2026-03-19: Edycja custom fields w koszyku — product_code przeliczany po zmianie, merge duplikatów przy identycznym hashu
- 2026-03-19: JS handlery koszyka w basket.php (nie basket-details.php) bo basket-details jest AJAX-replaceable
- 2026-03-25: view_cart event w basket.php (nie basket-details.php) — ten sam powód
- 2026-03-25: GA4 item format standard: item_id (string), item_name, price (number), quantity (int), google_business_vertical: "retail"
- 2026-03-25: Brak user_data w purchase — wymaga analizy RODO

### Deferred Issues
None.

### Blockers/Concerns
None.
