+# LoParkour — Гайд по патчам
+
+Все файлы в этом архиве заменяют оригинальные файлы проекта **1 к 1 по пути**.
+Просто скопируй их поверх своего src/ и пересобери проект.
+
+---
+
+## Что уже исправлено (этот архив)
+
+### 🔴 Патч 1 — SQL Injection (КРИТИЧНО)
+**Файлы:** `storage/StorageSQL.java`, `storage/SQLQueryExecutor.java`, `storage/SQLMigrationManager.java`
+
+Оригинальный код вставлял имена игроков, стили, локали напрямую в SQL строки через `.formatted()`.
+Игрок с ником `'; DROP TABLE loparkour-leaderboard-default; --` мог уничтожить таблицу лидерборда.
+
+**Что сделано:** Все запросы с пользовательскими данными переписаны на `?` плейсхолдеры.
+JDBC-драйвер сам экранирует значения — инъекция физически невозможна.
+
+---
+
+### 🔴 Патч 2 — ElytraMode полная переработка
+**Файлы:** `mode/ElytraMode.java`, `mode/ElytraGenerator.java`, `resources/config.yml`, `resources/locales/en.yml`
+
+Оригинальный ElytraMode был просто обычным паркуром с элитрой в инвентаре.
+Кольца лежали горизонтально (как блины), хитбокс был кубом 5×5×5,
+cooldown фейерверка не работал (показывал сообщение но не блокировал).
+
+**Что сделано:**
+- Генерируются кольца в воздухе по плавной кривой (настраивается в config.yml)
+- Кольца стоят вертикально, перпендикулярно направлению полёта
+- Детект пролёта через плоскость кольца (dot product, а не куб)
+- Firework перехватывается через `PlayerInteractEvent` — реально блокируется до использования
+- Boost выдаётся вручную через `setVelocity()` + визуальный фейерверк без урона
+- Action bar: счёт + дистанция до следующего кольца + cooldown
+
+---
+
+### 🟠 Патч 3 — SpeedrunMode не работал вообще
+**Файл:** `mode/SpeedrunMode.java`
+
+`onBlockTouch()` был объявлен но **нигде не вызывался** — блоки никогда не исчезали.
+Speedrun был идентичен обычному режиму.
+
+**Что сделано:** Подключился через `score()` override — вызывается в момент когда
+игрок встаёт на новый блок. Исправлено деление на 50 которое давало 0 тиков при
+малых значениях. Warning task теперь отменяется при reset().
+
+---
+
+### 🟠 Патч 4 — CoopMode показывался в одиночном меню
+**Файл:** `mode/CoopMode.java`
+
+`CoopMode implements Mode` вместо `MultiMode` — поэтому висел в меню рядом с Default/Speedrun.
+`SingleMenu` фильтрует `instanceof MultiMode`, но кооп им не был.
+
+**Что сделано:** `CoopMode implements MultiMode`. `getItem()` возвращает `null`.
+`create()` открывает лобби вместо создания сессии соло.
+Исправлен двойной счётчик (`sharedScore` дублировал `state.score`).
+`fall()` больше не чистит стейт который уже сброшен внутри `super.fall()`.
+
+---
+
+### 🟠 Патч 5 — RaceMode off-by-one + ActionBar конфликт
+**Файл:** `mode/RaceMode.java`
+
+Проверка финиша была в `tick()` — срабатывала на тик позже нужного.
+ActionBar обновлялся каждый тик конфликтуя с parent.
+`reset(false)` вызывался с задержкой без null-check — NPE если игрок вышел.
+
+**Что сделано:** Финиш проверяется в `score()` override — точно в момент достижения цели.
+Прогресс-бар обновляется только при новом очке. Добавлен guard `!state.stopped`.
+
+---
+
+## Что ещё нужно исправить (следующие шаги)
+
+### 🔴 Приоритет 1 — Ghost файлы по имени игрока (path traversal + коллизии)
+**Файл:** `ghost/GhostManager.java`
+
+```java
+// ПРОБЛЕМА:
+File file = new File(modeFolder, data.getPlayerName() + ".ghost");
+```
+
+Два игрока с одинаковым именем затирают друг друга.
+Игрок с именем `../../config` может писать за пределы папки плагина.
+
+**Как чинить:** Называть файлы по UUID игрока, не по имени.
+Хранить имя внутри файла (оно уже там есть в `GhostData`).
+
+---
+
+### 🟡 Приоритет 2 — Ghost не пишет всех игроков в мультиплеере
+**Файл:** `generator/lifecycle/GeneratorLifecycle.java`
+
+`GhostRecorder` записывает только `generator.player` (первый игрок сессии).
+В CoopMode и RaceMode остальные игроки не записываются.
+
+**Как чинить:** Recorder на каждого игрока отдельно, или писать только в single-player режимах.
+
+---
+
+### 🟡 Приоритет 3 — `disable()` глотает все исключения
+**Файл:** `LoParkour.java`
+
+```java
+} catch (Throwable ignored) { }
+```
+
+Если при выключении сервера не сохранятся данные — никто не узнает.
+
+**Как чинить:** Минимум логировать: `catch (Throwable t) { getLogger().severe(...) }`.
+
+---
+
+### 🟡 Приоритет 4 — `cleanupDistantBlocks()` вызывается дважды за тик
+**Файл:** `generator/lifecycle/GeneratorLifecycle.java`
+
+Вызывается явно в `tick()` И через отдельный `cleanupTask` таймер одновременно.
+
+**Как чинить:** Убрать явный вызов из `tick()`, оставить только таймер.
+
+---
+
+### 🟡 Приоритет 5 — `new Random()` в горячих методах
+**Файл:** `generator/jump/BlockPlacer.java`
+
+```java
+pool.get(new java.util.Random().nextInt(pool.size()))  // внутри tryGenerateSchematic()
+new java.util.Random().nextInt(rotations.length)        // внутри rotatedPaste()
+```
+
+Каждый вызов создаёт новый объект Random. Дорого и неправильно.
+
+**Как чинить:** Один `private static final ThreadLocalRandom RNG = ThreadLocalRandom.current()`
+на уровне класса.
+
+---
+
+### 🟡 Приоритет 6 — `System.err.println` в JumpOffsetGenerator
+**Файл:** `generator/jump/JumpOffsetGenerator.java`
+
+```java
+System.err.println("Warning: Unexpected jump height ...");
+```
+
+В Bukkit плагинах нельзя писать в System.err напрямую.
+
+**Как чинить:** `LoParkour.getPlugin().getLogger().warning(...)`.
+
+---
+
+### 🟢 Приоритет 7 — Пустой javadoc в LoParkour.java
+**Файл:** `LoParkour.java`
+
+Висит осиротевший javadoc от удалённого метода `getLogging()`. Не баг, просто мусор.
+
+---
+
+## Порядок следующих патчей (рекомендация)
+
+1. Ghost path traversal (безопасность)
+2. `disable()` silent catch (надёжность)
+3. `cleanupDistantBlocks` двойной вызов (производительность)
+4. `new Random()` в горячих путях (производительность)
+5. Ghost мультиплеер (функциональность)
+
+---
+
+## Патчи добавленные в эту версию архива
+
+### 🔴 Патч 6 — Ghost path traversal + коллизии по имени (БЕЗОПАСНОСТЬ)
+**Файлы:** `ghost/GhostData.java`, `ghost/GhostManager.java`, `ghost/GhostRecorder.java`, `generator/lifecycle/GeneratorLifecycle.java`
+
+Файлы назывались `playerName.ghost`. Два игрока с одинаковым ником затирали друг друга.
+Игрок с именем `../../config` мог писать файлы за пределы папки плагина (path traversal).
+
+**Что сделано:**
+- Файлы теперь называются `uuid.ghost` — уникально и filesystem-safe
+- `GhostData` хранит UUID (добавлен в конструктор и в бинарный формат)
+- `GhostRecorder.stopRecording()` принимает UUID + имя
+- `GhostManager.sanitizeMode()` чистит имя режима от слэшей
+- Старые файлы v1 (без UUID) автоматически удаляются при загрузке с логом
+- Формат файла версионирован (int VERSION=2 в начале)
+
+---
+
+### 🟡 Патч 7 — `cleanupDistantBlocks()` вызывался дважды за тик
+**Файл:** `generator/lifecycle/GeneratorLifecycle.java`
+
+Был явный вызов в `tick()` И таймер `cleanupTask` — двойная работа каждый тик.
+
+**Что сделано:** Убран явный вызов из `tick()`. Только таймер.
+
+---
+
+### 🟡 Патч 8 — `new Random()` в горячих методах BlockPlacer
+**Файл:** `generator/jump/BlockPlacer.java`
+
+`new java.util.Random()` создавался внутри `tryGenerateSchematic()` и `rotatedPaste()` при каждом вызове.
+
+**Что сделано:** Заменено на `ThreadLocalRandom.current().nextInt()`.
+
+---
+
+### 🟡 Патч 9 — `System.err.println` в JumpOffsetGenerator
+**Файл:** `generator/jump/JumpOffsetGenerator.java`
+
+**Что сделано:** Заменено на `LoParkour.getPlugin().getLogger().warning(...)`.
+
+---
+
+### 🟡 Патч 10 — `disable()` глотал все исключения молча
+**Файл:** `LoParkour.java`
+
+`catch (Throwable ignored) {}` — если данные не сохранялись при выключении сервера, никто не узнавал.
+
+**Что сделано:** `catch (Throwable t)` с логированием и `t.printStackTrace()`.
+
+---
+
+## Оставшиеся задачи
+
+### 🟡 Ghost мультиплеер
+`GhostRecorder` пишет только `generator.player` (первый игрок сессии).
+В CoopMode/RaceMode остальные игроки не записываются.
+**Решение:** Либо отдельный рекордер на каждого, либо запись только в single-player режимах.
+
+### 🟢 Осиротевший javadoc в LoParkour.java
+Комментарий от удалённого метода `getLogging()` — просто мусор, не баг.

- * Race Mode - First to reach target score wins
+ * Race Mode — reach the target score as fast as possible.
+ * Leaderboard sorts by time (fastest wins).
+ *
+ * <p>Bugs fixed vs previous version:
+ * <ul>
+ *   <li>{@code tick()} called {@code super.tick()} AND checked score every tick —
+ *       but super.tick() already calls {@code score()} internally, so the finish
+ *       check ran one tick late causing an off-by-one where state.score could
+ *       briefly exceed targetScore before finishing. Fixed by overriding
+ *       {@link #score()} instead — finish check fires the exact moment target is hit.</li>
+ *   <li>ActionBar was re-sent every tick inside tick() which conflicted with the
+ *       parent's ActionBar updates. Moved to score() so it updates only on change.</li>
+ *   <li>{@code reset(false)} was called via scheduler delay — if the player left the
+ *       server in those 5 seconds it would NPE. Now guarded with null-check.</li>
+ *   <li>{@code getFormattedTime()} is private in parent — accessed via
+ *       {@code getDetailedTime()} which is protected. Fixed method call.</li>
