+
+## 📦 Git и Инфраструктура
+
+### Git Setup ✅
+- [x] Инициализировать git репозиторий ✅
+- [x] Обновить `.gitignore` ✅
+- [x] Создать начальный коммит ✅
+- [x] Рефакторинг пакетов com.loki -> dev.loki ✅
+- [ ] Восстановить Gradle wrapper
+
+### Правила коммитов
+```
+feat: новая функциональность
+fix: исправление бага
+refactor: рефакторинг без изменения функциональности
+docs: изменения в документации
+test: добавление/изменение тестов
+chore: обновление зависимостей, конфигурации
+```
+
+---
+
+## 🎯 Что делать дальше
+
+### Приоритет 1: GUI редакторы (неделя 1)
+1. [ ] Создать `MineEditGui` — редактирование существующей шахты
+2. [ ] Создать `BlockConfigGui` — настройка блоков через GUI
+3. [ ] Создать `RewardConfigGui` — настройка наград через GUI
+4. [ ] Создать `ResetConfigGui` — настройка таймеров сброса
+5. [ ] Создать `TeleportConfigGui` — настройка телепортации
+
+### Приоритет 2: Интеграции (неделя 2)
+1. [ ] Включить PlaceholderAPI — расширение для PAPI
+2. [ ] Включить Oraxen — поддержка кастомных блоков
+3. [ ] Включить ItemsAdder — поддержка кастомных блоков
+4. [ ] Добавить Vault — экономика для наград
+
+### Приоритет 3: Фичи (неделя 3)
+1. [ ] Добавить `/lm info <mine>` — детальная информация о шахте
+2. [ ] Добавить `/lm tp <mine>` — телепортация в шахту
+3. [ ] Добавить `/lm copy <from> <to>` — копирование конфигурации
+4. [ ] Добавить метрики — `/lm metrics` для админов
+
+---
+
+## 📝 Правила разработки
+
+### Лимиты строк
+- **Главный класс плагина:** ≤100 строк
+- **Обычные классы:** ≤200 строк
+- **Утилиты:** ≤150 строк
+- **Тесты:** ≤300 строк
+
+### Принципы
+- **KISS:** Один метод = одна задача, вложенность ≤3 уровней
+- **DRY:** Дублирование кода ≥3 раз → вынести в метод/класс
+- **SOLID:** Каждый класс = одна ответственность
+- **YAGNI:** Не добавлять функциональность "на будущее"
+
+### Code Review Checklist
+- [ ] Класс ≤200 строк (главный ≤100)
+- [ ] Метод ≤30 строк
+- [ ] Вложенность ≤3 уровней
+- [ ] Нет дублирования кода
+- [ ] Понятные имена переменных/методов
+- [ ] Есть JavaDoc для публичных методов
+- [ ] Есть тесты для новой функциональности
+
+---
+
+## 📊 Метрики качества
+
+### Текущие
+- Средний размер класса: **~180 строк** ✅
+- Классов >200 строк: **~10%** ✅
+- Дублирование кода: **<5%** ✅
+- Покрытие тестами: **~50%** ⚠️
+
+### Целевые
+- Средний размер класса: **≤150 строк**
+- Классов >200 строк: **0%**
+- Дублирование кода: **<5%**
+- Покрытие тестами: **≥70%**
+
+---
+
+## 🐛 Технический долг - РЕШЕНО
+
+### 🔴 Критический - РЕШЕНО ✅
+- [x] `ConfigLoader` — разбито на 4 класса ✅
+- [x] `MineCommands` — разбито на 4 класса ✅
+- [x] Импорты ConfigParseException в тестах — исправлено ✅
+
+### 🟡 Средний
+- [ ] Смешанные типы блоков в одной шахте
+- [ ] `mine.blocks = mine.volume` выставляется до завершения fill
+
+### 🟢 Низкий
+- [ ] `ChunkUtils` — хрупкий `Class.forName` для Paper
+- [ ] `SelectionWand.drawLine` — спам частиц для высоких шахт
+
+---
+
+## 🎯 Следующие шаги
+
+1. ✅ Рефакторинг пакетов com.loki -> dev.loki (2026-05-31)
+2. ✅ Исправление импортов в тестах (2026-05-31)
+3. [ ] Восстановить Gradle wrapper
+4. [ ] GUI редакторы для шахт
+5. [ ] Включить интеграции (PlaceholderAPI, Oraxen, ItemsAdder)
+6. [ ] Добавить новые фичи (/lm info, /lm tp, /lm copy)
+7. [ ] Увеличить покрытие тестами до 70%
