+- [x] `!catperson` / `!dogperson` / `!foxperson` — «Какой ты кот/пёс/лис»: % + роль + картинка (детерминировано ID)
+- [x] `!shibe` / `!birb` — картинки шиба-ину и птичек
+- [x] `!neko` / `!waifu` / `!catboy` — аниме-картинки (неко, вайфу, кошко-мальчик)
+- [ ] Факты: `!catfact` / `!dogfact` — факт + картинка (catfact.ninja, dog facts API)
+- [ ] `!joke` — анекдоты (jokeapi.dev, категории Any/Programming/Misc)
+- [ ] `!chuck` — цитаты Чака Норриса (api.chucknorris.io)

+## ⚡ Стабильность и скорость (2026-08-19, аудит сервера 185.176.94.38)
+
+### Найдено в логах
+| # | Проблема | Статус |
+|---|----------|--------|
+| S01 | `LogEmbeds.ban`/`kick` — NPE `Value may not be null`, если бан/кик без причины (падал onSuccess-колбэк, терялся лог) | ✅ `reason != null ? reason : "Не указана"` |
+| S02 | `RatingService.getDeterministicValue` — гонка на общем `Random.setSeed()`: 2 пользователя одновременно → результаты «подменялись» | ✅ локальный `new Random(seed)` (thread-safe) |
+| S03 | Пул репортов на внешние API отсутствовал | ✅ `util/ApiRequestQueue` (пул 4, изоляция ответов) |
+| S04 | `Missed 2 heartbeats` — 1 раз, транзиентный (сеть), не повторяется | ➖ наблюдать |
+
+### Что сделано
+- `util/ApiRequestQueue` — очередь исходящих запросов: каждый запрос выполняется изолированно, ответ не может подмешаться к соседнему, пул 4 не перегружает публичные API. Подключён в `AnimalApi` и `NekosLifeApi`, зарегистрирован в LifecycleModule (graceful shutdown)
+- `RatingService` — детерминированное значение теперь без общего `Random` (root cause «подмены ответов»)
+- `LogEmbeds.ban/kick` — дефолт причины «Не указана»
+
+### Производительность (наблюдения)
+- Команды выполняются за 0–100 мс (virtual threads), CPU ~0.2%, RAM 186 МБ — узких мест нет
+- Основная задержка — внешние HTTP API (таймауты 10 с + retry с бэк-оффом); очередь ограничивает параллелизм до 4
+
+### Оптимизации (2026-08-19)
+- [x] `AnimalApi` — Caffeine-кэш успешных URL (TTL 30 с): повторные `!neko`/`!catboy`/зоо-викторины отвечают мгновенно
+- [x] `MemeCommand` — HttpURLConnection (без таймаутов, мог висеть) → OkHttp 6с/8с
+- [ ] `Database` — включить `PRAGMA journal_mode = WAL` (сейчас нет — блокировки при конкурентной записи)
+- [ ] NekosLifeApi — таймауты/ретраи вынести в конфиг (10с → 8с, retry 3 → 2)
+- [ ] Негативный кэш неудачных запросов в AnimalApi (не долбить упавший API 30с)
+- [ ] Dockerfile — JVM флаги (`-Xmx512m -XX:+UseG1GC -XX:+UseStringDeduplication`)
+- [ ] Разобрать остальные `HttpURLConnection` на общий OkHttp-клиент
+
+---
+
+## 🚧 v2.5 — Java 25, рейтинги, память (2026-08-19)
+
+### 1. Java 26 + Gradle 9.7.0
+- [x] `build.gradle`: `toolchain { languageVersion = 26 }` — Gradle сам находит JDK 26 (`/usr/lib/jvm/java-26-openjdk`), `export JAVA_HOME` больше не нужен
+- [x] `.java-version` (файл `26`) — для IDE/jenv/asdf
+- [x] `gradle/wrapper/gradle-wrapper.properties`: 9.3.1 → 9.7.0 (системный gradle 9.7.0 в `/usr/bin/gradle`)
+- [x] `Dockerfile`: `eclipse-temurin:21-jdk-alpine` → `26-jdk-alpine`, `21-jre-alpine` → `26-jre-alpine`
+- [x] Mockito 5.15.2 тянет ByteBuddy 1.14.x (не знает класс-файлы major 70) → добавить `byte-buddy:1.18.8` (уже в кэше, поддержка Java 26)
+- [x] CI workflows (ci/docker-publish/release): `java-version: "21"` → `"26"`
+- [x] Пересобрать локально + `spotlessApply` (Spotless 6.25→8.10.0, SpotBugs 4.9.3→4.10.3 для major 70; 458 тестов ✅)
+
+### 1.1 Обновление зависимостей (2026-08-19, все 20)
+- [x] jda 6.4.2→6.5.0, lavaplayer 2.2.6→2.2.7, logback 1.5.18→1.6.3, caffeine 3.2.0→3.2.4
+- [x] sqlite 3.49.1.0→3.53.2.1, **hikaricp 6.3.0→7.1.0** (мажор, API совместим, тесты ✅), okhttp 5.4.0→5.5.0
+- [x] junit 5.12.1→5.13.4, junit-platform-launcher 1.12.1→1.13.4, mockito 5.15.2→5.23.0, bytebuddy 1.18.8→1.18.12
+- [x] **slf4j 2.1.0-alpha1 → 2.0.18** (стабильный вместо alpha)
+- [x] checkstyle 10.23.0→13.10.0 (toolVersion, требует Java 21+ ✓), spotbugsPlugin 6.1.7→6.4.8, jsoup 1.19.1→1.22.2
+- [x] gson 2.14.0, guice 7.0.0, lavalinkClient 3.4.0, dotenv 3.2.0, spotbugs 4.10.3 — актуальные, без изменений
+
+### 2. `!generateratings` генерит только на 2 человек
+- [x] **Причина**: JDA `MemberCachePolicy.DEFAULT` кэширует только голосовых/owner/self + `ChunkingFilter` по умолчанию чанкует только гильдии ≥250 участников → `guild.getMembers()` = 2
+- [x] `core/JdaFactory.java`: `.setMemberCachePolicy(MemberCachePolicy.ALL)` + `.setMemberChunkingFilter(ChunkingFilter.ALL)`
+- [x] `GenerateRatingsCommand.java`: `guild.getMembers()` → `guild.loadMembers().get()` (подстраховка)
+
+### 3. Команда топа/низа рейтингов
+- [x] `RatingsRepository`: `getTopRatings(guildId, type, limit)` + `getBottomRatings(...)` (ORDER BY value DESC/ASC LIMIT)
+- [x] Новая команда `feature/rating/commands/board/RatingBoardCommand` — флейворы `ratingstop`/`ratingbottom` (высшие/низшие), рендер `<@id> — value` без резолва участников, медали топ-3
+- [x] Зарегистрировать в `feature/utility/UtilityCommandRegistrar` (рядом с GenerateRatingsCommand)
+
+### 4. Лимит памяти 1 ГБ
+- [x] `docker-compose.yml`: сервис `bot` → `mem_limit: 1g`
+- [x] `Dockerfile` ENTRYPOINT: JVM-флаги `-Xmx512m -XX:+UseG1GC -XX:+UseStringDeduplication`
+
+### 5. Дальнейшие оптимизации (поиск)
+- [x] Изучено: Gradle 9.4+ нужен для Java 26 (9.7.0 ✓); Gradle 8.14.3 падает на major 69/70; JDA — `loadMembers()` требует GUILD_MEMBERS intent (у бота включён)
+- [ ] `Database`: `PRAGMA journal_mode = WAL`
+- [ ] NekosLifeApi: таймауты/ретраи в конфиг
+- [ ] Негативный кэш в AnimalApi
+- [ ] Свести все HttpURLConnection на OkHttp

+#   gradlew start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh gradlew
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
