requires:
  - phase: 02-form-ui-step1
    provides: Form UI with segment/branch filtering, validation, data collection
provides:
  - Complete booking flow: customer creation → pricing summary → reservation → confirmation
  - Address and PESEL fields for API compliance
  - Pricing summary overlay with cost breakdown
  - Success view with reservation number
affects: [04-polish-testing, 05-admin-panel]

key-decisions:
  - "Boolean values for Java API (true/false not 'T'/'N') despite documentation saying otherwise"
  - "Simplified segments-branches-map: 2 API calls instead of ~40 — all branches shown for all segments"
  - "drivers[] required in makebooking — populated from form data (same person as customer)"
  - "skipAccountCreate: true — no customer account, MVP approach"
  - "Penalty items (BRAK, BRUD, KARA) filtered out from extras display"

patterns-established:
  - "Softra API uses Java boolean deserialization — always send true/false, never 'T'/'N'"
  - "Multi-step API flow with error recovery at each step"

# Phase 3 Plan 01: Submit + Booking Flow Summary

**Pełny flow rezerwacji: formularz → tworzenie klienta → podsumowanie kosztów w overlay → złożenie rezerwacji → potwierdzenie z numerem.**

## Performance

| Metric | Value |
|--------|-------|
| Duration | ~2h |
| Tasks | 3 completed |
| Files modified | 5 |

## Acceptance Criteria Results

| Criterion | Status | Notes |
|-----------|--------|-------|
| AC-1: Dodatkowe pola (adres, PESEL) | Pass | Miejscowość, kod pocztowy, ulica, PESEL — wymagane, walidowane |
| AC-2: Submit tworzy klienta i pokazuje podsumowanie | Pass | customer/add → princingSummary → overlay z tabelą kosztów i wszystkimi wybranymi opcjami |
| AC-3: Potwierdzenie rezerwacji kończy flow | Pass | makebooking → confirm → success view z numerem rezerwacji |

## Accomplishments

- Pełny booking flow działa end-to-end na produkcji
- Overlay podsumowania pokazuje: dane wynajmu, najemcę, wybrane opcje, tabelę kosztów (netto/VAT/brutto)
- Error handling na każdym kroku z czytelnym komunikatem
- Endpoint /booking/cancel dodany (UI do wykorzystania w przyszłości)

## Files Modified

| File | Change | Purpose |
|------|--------|---------|
| `includes/class-elementor-widget.php` | Modified | Pola adresowe + PESEL, overlay podsumowania, success view |
| `assets/css/carei-reservation.css` | Modified | 800+ linii — style summary, success, address row |
| `assets/js/carei-reservation.js` | Modified | 730+ linii — pełny booking flow z error handling |
| `includes/class-softra-api.php` | Modified | cancel_booking(), uproszczone segments-branches-map (2 calls) |
| `includes/class-rest-proxy.php` | Modified | Endpoint POST /booking/cancel |

## Decisions Made

| Decision | Rationale | Impact |
|----------|-----------|--------|
| Boolean zamiast string w API | Java deserializacja nie akceptuje 'T'/'N', wymaga true/false | Wszystkie pola boolean muszą być native boolean |
| Uproszczone mapowanie segment→branch | 39 oddziałów × 30s timeout = niemożliwe w jednym request | Wszystkie oddziały dostępne dla każdego segmentu, API weryfikuje przy rezerwacji |
| drivers[] z danymi najemcy | API wymaga (NotNull), dokumentacja nie zaznacza jako required | Kierowca = ten sam co najemca formularza |

## Deviations from Plan

### Summary

| Type | Count | Impact |
|------|-------|--------|
| Auto-fixed | 3 | API compatibility fixes discovered during testing |

### Auto-fixed Issues

**1. Boolean serialization**
- Issue: isCompany='N', skipAccountCreate='T' → HTTP 400
- Fix: Changed to isCompany: false, skipAccountCreate: true
- Verification: customer/add returns 200 with customerId

**2. Segments-branches-map timeout**
- Issue: ~40 sequential API calls → cURL timeout after 30s
- Fix: Simplified to 2 API calls (branches + car-classes-all), all branches shown for all segments
- Verification: Endpoint returns in <2s

**3. Missing drivers field**
- Issue: makebooking requires drivers[] (NotNull), not documented as required
- Fix: Added drivers array with form data (firstName, lastName, address, pesel, phone, email)
- Verification: makebooking returns success with reservationId

## Next Phase Readiness

**Ready:**
- Rezerwacja działa end-to-end
- Wszystkie endpointy API przetestowane na produkcji
- Error handling na każdym kroku

**Concerns:**
- Penalty items z pricelist filtrowane po kodzie (BRAK/BRUD/KARA) — może nie pokryć wszystkich
- Brak email notification po rezerwacji (zależy od konfiguracji Softra)

**Blockers:** None
