+# PAUL Handoff
+
+**Date:** 2026-03-16
+**Status:** paused — checkpoint human-verify in progress
+
+---
+
+## READ THIS FIRST
+
+You have no prior context. This document tells you everything.
+
+**Project:** orderPRO — aplikacja do zarządzania zamówieniami z wielu platform
+**Core value:** Sprzedawca może obsługiwać zamówienia ze wszystkich kanałów sprzedaży i nadawać przesyłki bez przełączania się między platformami.
+
+---
+
+## Current State
+
+**Milestone:** v0.4 Moduł E-mail
+**Phase:** 14 of 3 (in milestone) — Szablony wiadomości e-mail
+**Plan:** 14-01 — APPLY in progress (checkpoint human-verify)
+
+**Loop Position:**
+```
+PLAN ──▶ APPLY ──▶ UNIFY
+  ✓        ◐        ○     [APPLY in progress — Task 1+2 done, Task 3 checkpoint awaiting approval]
+```
+
+---
+
+## What Was Done
+
+- Task 1: Created `EmailTemplateRepository` + `EmailTemplateController` + routes (6 endpoints)
+- Task 2: Created view `email-templates.php` with Quill.js CDN editor, variable panel, preview modal, AJAX toggle
+- Added sidebar link "Szablony e-mail" in `layouts/app.php`
+- Compiled SCSS (modal-overlay, email-tpl-editor styles)
+- Fixed 2 bugs discovered during deploy:
+  - `AuthService` namespace: `App\Core\Auth\AuthService` → `App\Modules\Auth\AuthService`
+  - `Flash` namespace: `App\Core\Session\Flash` → `App\Core\Support\Flash`
+
+---
+
+## What's In Progress
+
+- **Task 3 checkpoint:human-verify** — user was testing the deployed page when session paused
+- User reported 2 namespace errors which were fixed, needs to re-test
+
+---
+
+## What's Next
+
+**Immediate:** User re-tests `/settings/email-templates` after namespace fixes. If approved → APPLY complete.
+
+**After that:** Run `sonar-scanner` (required skill), then `/paul:unify .paul/phases/14-email-templates/14-01-PLAN.md`
