## Performance

| Metric | Value |
|--------|-------|
| Duration | ~15min |
| Completed | 2026-03-15 |
| Tasks | 4 completed |
| Files modified | 8 |

## Acceptance Criteria Results

| Criterion | Status | Notes |
|-----------|--------|-------|
| AC-1: Tabele paragonow istnieja po migracji | Pass | receipt_configs, receipts, receipt_number_counters utworzone |
| AC-2: Company settings rozszerzony | Pass | bdo_number, regon, court_register, logo_path dodane |
| AC-3: Formularz wyswietla i zapisuje nowe pola | Pass | Zweryfikowane manualnie przez uzytkownika |
| AC-4: Dokumentacja zaktualizowana | Pass | DB_SCHEMA.md i ARCHITECTURE.md zaktualizowane |

## Accomplishments

- 3 nowe tabele bazodanowe dla modulu paragonow (receipt_configs, receipts, receipt_number_counters)
- Rozszerzenie company_settings o 4 pola wymagane na dokumentach ksiegowych
- Formularz danych firmy zaktualizowany o nowe pola z pelnym zapisem/odczytem

## Files Created/Modified

| File | Change | Purpose |
|------|--------|---------|
| `database/migrations/20260315_000050_*.sql` | Created | Tabela receipt_configs |
| `database/migrations/20260315_000051_*.sql` | Created | Tabela receipts |
| `database/migrations/20260315_000052_*.sql` | Created | Tabela receipt_number_counters |
| `database/migrations/20260315_000053_*.sql` | Created | Rozszerzenie company_settings |

## Decisions Made

| Decision | Rationale | Impact |
|----------|-----------|--------|
| receipts.order_id BIGINT UNSIGNED | orders.id jest BIGINT UNSIGNED — FK musi sie zgadzac | Fix bledu errno 150 |
| ON DELETE RESTRICT dla receipt_configs | Nie mozna usunac konfiguracji jesli istnieja paragony | Bezpieczenstwo danych |
| Logo jako sciezka tekstowa | Upload w przyszlosci, na razie pole tekstowe | Uproszczenie fazy 08 |

## Deviations from Plan

### Summary

| Type | Count | Impact |
|------|-------|--------|
| Auto-fixed | 1 | Krytyczny fix typu FK |

**Total impact:** Jeden fix krytyczny, brak scope creep.

### Auto-fixed Issues

**1. FK type mismatch receipts.order_id**
- **Found during:** Task 1 (migracje)
- **Issue:** receipts.order_id bylo INT UNSIGNED, orders.id jest BIGINT UNSIGNED
- **Fix:** Zmieniono na BIGINT UNSIGNED
- **Files:** database/migrations/20260315_000051_create_receipts_table.sql
- **Verification:** Migracja wykonana pomyslnie po poprawce

## Issues Encountered

| Issue | Resolution |
|-------|------------|
| errno 150 FK constraint | Poprawiono typ order_id z INT na BIGINT UNSIGNED |

## Next Phase Readiness

**Ready:**
- Tabele bazodanowe gotowe pod CRUD konfiguracji (faza 09)
- Company settings kompletne pod snapshot danych sprzedawcy

**Concerns:**
- Brak

**Blockers:**
- Brak
