+# SUMMARY: 06-04 — Cognitive Complexity (S3776)
+
+## Status: COMPLETE
+
+## Execution Log
+
+### Task 1: AllegroIntegrationController
+- **oauthCallback()** — już uproszczone z poprzedniego planu (AC-1 ✓ bez zmian)
+- **loadDeliveryServices()** — zrefaktoryzowane: wydzielono 3 private helpers:
+  - `loadAllegroDeliveryServices(array $settings): array`
+  - `fetchAllegroDeliveryResponse(string $env, string $accessToken, array $oauth): array`
+  - `loadApaczkaServices(): array`
+  - Główna metoda: max 2 poziomy zagnieżdżenia (z 5) ✓
+- `php -l` — PASS ✓
+
+### Task 2: ShopproIntegrationsController
+- **saveStatusMappings()** — już max 2 poziomy zagnieżdżenia (AC-3 ✓ bez zmian)
+- **loadDeliveryServices()** — zrefaktoryzowane: wydzielono 3 private helpers:
+  - `loadAllegroDeliveryServices(): array`
+  - `fetchAllegroDeliveryResponse(string $env, string $accessToken, array $oauth): array`
+  - `loadApaczkaServices(): array`
+  - Główna metoda: max 2 poziomy zagnieżdżenia (z 5) ✓
+- `php -l` — PASS ✓
+
+### Task 3: ShopproOrdersSyncService
+- **sync()** — już w pełni zrefaktoryzowane z planu 06-06:
+  - `sync()` → `syncOneIntegration()` → `processPageCandidates()` → `importOneOrder()`
+  - `sync()` max 2 poziomy, `syncOneIntegration()` max 3 poziomy ✓
+- AC-4 i AC-5 spełnione bez dodatkowych zmian ✓
+- `php -l` — PASS ✓
+
+## Verification Checklist
+- [x] php -l AllegroIntegrationController.php — 0 błędów
+- [x] php -l ShopproIntegrationsController.php — 0 błędów
+- [x] php -l ShopproOrdersSyncService.php — 0 błędów
+- [x] loadDeliveryServices() (Allegro) — max 2 poziomy zagnieżdżenia
+- [x] loadDeliveryServices() (Shoppro) — max 2 poziomy zagnieżdżenia
+- [x] sync() (ShopproOrdersSyncService) — max 3 poziomy zagnieżdżenia
+- [x] sonar-scanner uruchomiony — ANALYSIS SUCCESSFUL
+
+## Deviations
+- AC-1 (oauthCallback) i AC-4 (sync) były już spełnione z poprzednich planów
+- AC-3 (saveStatusMappings) był już spełniony — pętla for z if na 2 poziomach
+- Refaktoryzacja skupiona na loadDeliveryServices() w obu kontrolerach (faktyczny problem)
+
+## Files Modified
+- `src/Modules/Settings/AllegroIntegrationController.php` — loadDeliveryServices() + 3 nowe helpers
+- `src/Modules/Settings/ShopproIntegrationsController.php` — loadDeliveryServices() + 3 nowe helpers
+- `src/Modules/Settings/ShopproOrdersSyncService.php` — bez zmian (już OK)
