## READ THIS FIRST

You have no prior context. This document tells you everything.

**Project:** Carei — Formularz rezerwacji samochodu jako plugin Elementor, zintegrowany z Softra Rent API
**Core value:** Klient klika "Złóż zapytanie o rezerwację" → modal z formularzem → dane z API Softra → rezerwacja

---

## Current State

**Milestone:** v0.1 Formularz Rezerwacji MVP
**Phase:** 3 of 5 — Complete ✅
**Plan:** 03-01 — Complete

**Loop Position:**
```
PLAN ──▶ APPLY ──▶ UNIFY
  ✓        ✓        ✓     [Loop complete — ready for next PLAN]
```

## What Was Done

**This session:**
- Refactored form layout: segment+dates in one row, pickup+same-return checkbox in one row
- New endpoint `/segments-branches-map` (simplified: 2 API calls, all branches for all segments)
- Segment→branch filtering in pickup select (all branches shown, API verifies at booking)
- Extras hidden until segment AND pickup selected
- Investigated API for insurance (none) and foreign travel (none) → deferred to backlog
- Added Phase 5 to roadmap: Admin Panel historia formularzy
- **Phase 3 complete:** full booking flow end-to-end
  - Added address fields (city, zipCode, street) + PESEL
  - Pricing summary overlay with cost breakdown table
  - Success view with reservation number
  - customer/add → princingSummary → makebooking → confirm
  - Error handling at each step

**API discoveries (critical for future work):**
- Boolean params: must send `true`/`false`, NOT `'T'`/`'N'` (Java deserialization)
- `drivers[]` is required in makebooking (not documented as required)
- Penalty items in pricelist (BRAK/BRUD/KARA codes) filtered from display
- No insurance or foreign travel endpoints in current API version

---

## What's Next

**Immediate:** `/paul:plan` for Phase 4 — Polish & Integration Testing
- Edge cases (brak dostępności, timeout tokenu, błędy API)
- Animacje przejść form↔summary↔success
- Accessibility
- End-to-end testing on carei.pagedev.pl

**After that:**
- Phase 5: Admin Panel — zapisywanie formularzy w WP, przeglądanie w wp-admin

**Backlog (czeka na nową wersję API):**
- Ubezpieczenie (Pakiet Soft/Premium)
- Wyjazd zagraniczny (checkbox + wyszukiwarka krajów)

## Key Decisions Made

| Decision | Rationale |
|----------|-----------|
| Boolean API params (true/false) | Java backend rejects 'T'/'N' strings |
| Simplified branch mapping (no per-branch filtering) | 39 branches × API call = timeout; all branches shown, API verifies at booking |
| drivers[] = najemca | API requires NotNull, form collects same data |
| skipAccountCreate: true | MVP — no customer accounts needed |
| Penalty items filtered by code prefix | BRAK/BRUD/KARA not customer-facing options |
| Ubezpieczenie + wyjazd zagraniczny → backlog | API has no dedicated endpoints |
