-# tgit
+# tgit — git в Телеграме
 
-Телеграм-бот для загрузки кода в репозиторий и работы с ним. Простыми словами — расширенный git внутри Telegram-бота.
-
-Бот принимает `.py`-файлы и коммитит их в репозиторий на SourceCraft, где автоматически запускается CI/CD;
-сообщает статус пайплайна, присылает алерты, отдаёт логи и отвечает на вопросы по ним через LLM.
+Телеграм-бот для команды, которая ведёт общий репозиторий небольших Python-сервисов. Прямо из чата можно поправить
+код и закоммитить его, посмотреть, живы ли контейнеры, поискать по логам — своим grep или вопросом LLM-агенту, —
+и получать алерты, когда что-то упало.
 
 Учебный проект, курс Python, НИУ ВШЭ.

+---
+
+## 1. Цели и задачи
+
+**Цель** — сделать так, чтобы мелкие правки в общем коде и разбор инцидентов не требовали ноутбука с git и SSH:
+всё, что обычно делают в терминале, доступно из Телеграма, причём безопасно для сервера.
+
+**Задачи:**
+- пускать в бота только своих — по одноразовому QR-приглашению, без регистрации;
+- редактировать файлы репозитория и коммитить их из чата с проверкой до пуша;
+- показывать состояние контейнеров и запускать проверки здоровья по кнопке;
+- давать логи — хвост, grep и вопрос на естественном языке, — не открывая shell и не отдавая логи в LLM;
+- сообщать всей команде о падениях и перегрузках без спама;
+- защищаться от «случайных людей» и попыток взлома через бота.
+
+## 2. Что реализовано
+
+| Раздел | Возможности | Требования |
+|---|---|---|
+| **Доступ** | вход только по одноразовому QR (TTL 24 ч), роли админ/участник, отзыв доступа сразу, молчание на перебор токенов (> 5 неудач в час) | A-1…A-8 |
+| **📝 Коммит** | навигация по папкам, просмотр файла, новый файл/папка, замена (текстом или документом), удаление; проверка имени, размера, UTF-8 и синтаксиса Python; черновик до 50 изменений; сообщение коммита; push с проверкой конфликтов и «Перезаписать» | C-1…C-34 |
+| **🩺 Статус** | все контейнеры 🟢/🟡/🔴/⚪; карточка — health, аптайм, рестарты, CPU/RAM от лимита, ревизия и время деплоя; «🩺 Запустить проверки» — 7 независимых проверок с таймаутами | S-1…S-4 |
+| **📜 Логи** | хвост 50/200 строк или 5 мин/1 ч/24 ч; свой grep (`-i -v -E -c -C N`), выполняется в Python, не в shell; длинный ответ — файлом; журнал поисков | L-1…L-6 |
+| **🤖 Агент** | вопрос словами → фильтр → LLM-страж → LLM строит только `LogQuery` → валидация → grep; показывает построенную команду и строки; атака — отказ и 🛡 админам; 30 вопросов в сутки | L-10…L-17 |
+| **🚨 Алерты** | 💥 краш, 🧠 OOM, 🔁 цикл рестартов, 🩺 unhealthy, 🔥 перегрузка, 💾 мало места, 🔌 Docker недоступен, 🛡 атака; всем участникам, с хвостом лога и кнопками; повторы — счётчик, «✅ восстановлено» ответом; список за 7 дней | AL-1…AL-6 |
+| **CI/CD бота** | Gitea Actions: ruff, mypy strict, миграции up/down/up на PostgreSQL, pytest с порогом покрытия 80 %; автодеплой `dev` на сервер с проверкой health | ADR-015 |
+
+Качество: 296 тестов, покрытие 92 %, `mypy --strict`, `ruff`. Telegram в тестах — фейковая сессия aiogram,
+Docker — фейковый Engine API на `httpx.MockTransport`, LLM — сценарный фейк.
+
+## 3. Развёртывание и запуск
+
+### Требования
+
+- Python 3.12 и [uv](https://docs.astral.sh/uv/) — для запуска без Docker и тестов;
+- Docker 24+ с Compose v2 — для полного стека;
+- токен бота от [@BotFather](https://t.me/BotFather) и ваш Telegram ID (узнать — у [@userinfobot](https://t.me/userinfobot));
+- для агента логов — OpenAI-совместимый LLM с structured output (`response_format: json_schema`).
+
+Один токен — один запущенный экземпляр: Telegram отдаёт обновления только одному процессу.
+
+### Вариант А — локально за 5 минут (без Docker для бота)
+
+```bash
+git clone https://gitea.24studbank.ru/HSE/tgit.git && cd tgit
+make install                      # uv sync
+cp .env.example .env              # впишите TELEGRAM_BOT_TOKEN и ADMIN_IDS
+make demo-repo                    # локальный репозиторий загрузок из шаблона
+#   → допишите напечатанную строку GIT_UPLOADS_URL=... в .env
+make run                          # бот запущен, база — SQLite ./tgit.db
+```
+
+Чтобы заработали «Статус», «Логи» и алерты, нужен Docker API:
+
+```bash
+make local-proxy                  # read-only прокси Docker на 127.0.0.1:23750
+echo DOCKER_URL=http://127.0.0.1:23750 >> .env
+make demo-up                      # демо-сервисы: здоровый, падающий, CPU-hog, unhealthy
+make run
+```
+
+### Вариант Б — полный стек в Docker
+
+```bash
+cp .env.example .env              # токен, ADMIN_IDS, репозиторий загрузок и ключ (см. ниже)
+make up                           # бот + PostgreSQL 16 + docker-socket-proxy
+make demo-up                      # по желанию: демо-сервисы рядом с ботом
+make logs                         # логи бота
+```
+
+В Docker бот ходит в репозиторий загрузок по SSH: нужен отдельный репозиторий (шаблон —
+[`infra/uploads-template/`](infra/uploads-template/)) и deploy-ключ с правом записи. Ключ передаётся в
+`GIT_SSH_KEY_B64` (`base64 -w0 <ключ>`): смонтированный файл контейнер прочитать не сможет.
+
+### Сервер
+
+CD из Gitea Actions разворачивает `dev` на сервер скриптом `infra/deploy/deploy.sh` — его же можно запускать
+руками для любого хоста. Подробно — в [`docs/dev/DEPLOY.md`](docs/dev/DEPLOY.md).
+
+### Переменные окружения
+
+Полный список с комментариями — [`.env.example`](.env.example). Секреты хранятся только в `.env`, в git не попадают.
+
+| Переменная | Обязательна | Что задаёт |
+|---|---|---|
+| `TELEGRAM_BOT_TOKEN` | да | токен бота |
+| `ADMIN_IDS` | да | Telegram ID первых администраторов через запятую |
+| `TELEGRAM_PROXY_URL` | нет | HTTP/SOCKS-прокси до Telegram (если сервер не видит api.telegram.org) |
+| `GIT_UPLOADS_URL` | да | репозиторий загрузок: путь, `ssh://…` или `git@…` |
+| `GIT_SSH_KEY_B64` / `GIT_SSH_KEY_PATH` | для SSH | deploy-ключ бота |
+| `DATABASE_URL` | нет | по умолчанию SQLite; в Compose — PostgreSQL |
+| `DOCKER_URL` | нет | docker-socket-proxy; без него «Статус», «Логи» и алерты отвечают «Docker недоступен» |
+| `LLM_PROVIDER`, `LLM_BASE_URL`, `LLM_MODEL`, `LLM_API_KEY` | нет | LLM для агента; при `mock` агент выключен |
+
+### Проверки
+
+```bash
+make lint      # ruff + mypy --strict
+make test      # pytest
+make cov       # pytest с покрытием (порог 80 %)
+```
+
+## 4. Входные и выходные данные
+
+### Команды и кнопки
+
+| Ввод | Что происходит |
+|---|---|
+| `/start <токен>` (ссылка из QR) | регистрация по приглашению, главное меню |
+| `/start`, `/menu` | главное меню; из любого шага диалога |
+| `/help` | справка |
+| 📝 Коммит · 🩺 Статус · 📜 Логи · 🚨 Алерты | разделы; у админа ещё 👥 Участники (приглашения, отзыв) |
+
+Внутри разделов — инлайн-кнопки. Текстом бот принимает имя файла или папки, содержимое файла (текстом, в том числе
+в блоке ```` ``` ````, или документом до 100 КБ), сообщение коммита, выражение grep и вопрос агенту.
+
+### Выходные данные
+
+- **В Телеграме**: экраны разделов, файлы (`.log` для длинных результатов, исходник для больших файлов),
+  QR-приглашения PNG, алерты.
+- **В репозитории загрузок**: коммиты от `tgit-bot` с автором из Телеграма; push в `main` запускает CI репозитория.
+- **В БД** (13 таблиц, миграции Alembic): участники и приглашения, черновики, состояние диалогов, снапшоты
+  контейнеров, алерты и их доставки, журналы поисков по логам и вопросов агенту.
+
+### Используемые API
+
+| API | Зачем | Как |
+|---|---|---|
+| Telegram Bot API | весь интерфейс | aiogram 3, long polling |
+| git (SSH) | чтение и коммиты в репозиторий загрузок | `git` подпроцессом со своим ключом, без shell |
+| Docker Engine API | контейнеры, stats, логи | только GET через `docker-socket-proxy` |
+| OpenAI-совместимый `/chat/completions` | страж и планировщик агента | httpx, `response_format: json_schema` |
+| SourceCraft REST API | статус прогонов CI репозитория загрузок | httpx, клиент готов, в UI — #11 |
+
+## 5. Ограничения и особенности
+
+**Безопасность:**
+- Docker-сокет есть только у прокси, и тот пропускает лишь `GET /containers/*`. Бот показывает только контейнеры с меткой
+  `tgit.managed=true` и отказывает по чужому id ещё до запроса: на сервере живут и другие проекты.
+- grep разбирается `shlex.split` и выполняется модулем `regex` с таймаутом на строку и общим бюджетом 3 с;
+  катастрофический шаблон вроде `(a|aa)+$` бота не вешает.
+- Агент: логи в LLM **не передаются** (только вопрос и имена контейнеров), поэтому prompt injection из логов невозможен.
+  LLM может вернуть только `LogQuery` — контейнер из белого списка, период ≤ 7 дней, шаблон ≤ 200 символов без
+  вложенных квантификаторов. Даже обманутый страж даёт в худшем случае медленный grep.
+- Пути `.git/`, `.sourcecraft/`, `.tgit/` и `ruff.toml` из Телеграма не редактируются. Бот проверяет синтаксис
+  до пуша, но код сервисов не исполняет.
+
+**Лимиты:**
+
+| Что | Лимит |
+|---|---|
+| файл из Телеграма | 100 КБ, UTF-8 |
+| черновик | 50 изменений |
+| push | 20 в час на участника |
+| шаблон grep | 200 символов; вывод — 500 строк |
+| чтение логов | 50 000 строк и 5 МБ (новейшие) |
+| вопрос агенту | 500 символов, 30 в сутки |
+| повтор алерта | в течение 10 мин — счётчик, а не новое сообщение |
+
+**Что пока не сделано** (открытые задачи):
+- запуск сервисов из репозитория загрузок в песочнице (`--cap-drop ALL`, read-only FS, лимиты) и перезапуск из бота —
+  `tgit-runner`, #13. Сейчас сервисы поднимаются Compose, как в `examples/`;
+- уведомления о прогонах CI/CD репозитория загрузок и алерты 📦/⛔ — #11, ждут возврата к SourceCraft;
+- «🔕 Тишина на час» для алертов (P2);
+- prod-окружение: нужен отдельный бот, деплой `main` пропускается, пока его нет.

-  очередь отправки); `alert_deliveries` хранит `chat_id`/`message_id` — чтобы обновлять счётчик и отвечать «✅ восстановлено».
-- **Восстановление**: детектор сообщает, что условие прошло → `resolved_at`, ответ на исходные сообщения.
-- **Список**: активные + история 7 дней, пагинация.
+- **Детекторы** (`detectors.py`) — чистые функции «наблюдение за раунд + история снапшотов → условия, которые
+  выполняются сейчас»: 💥 краш (выход ≠ 0), 🧠 OOM, 🔁 ≥ 3 рестарта за 10 мин, 🩺 unhealthy, 🔥 CPU > 80 % или
+  RAM > 90 % на протяжении минуты, 💾 < 10 % свободного места на разделе тома бота, 🔌 Docker API недоступен > 5 мин.
+  Пороги — `config/alerts.yaml`. Монитор (`monitor.py`) вызывается после каждого раунда снапшотов (15 с).
+- **По состоянию, а не по событиям**: сервис сверяет условия с открытыми алертами — новое открывает алерт, пропавшее
+  закрывает. Пропущенное событие не теряет алерт, а бесконечный рестарт остаётся одним алертом.
+- **Дедупликация** (`service.py`): ключ `kind + service`. Условие, вернувшееся в течение 10 мин после закрытия, снова
+  открывает тот же алерт с `count += 1`: исходные сообщения редактируются, новые не шлются.
+- **Разовые события** (🛡 атака через агента; 📦 CD и ⛔ отказ после деплоя — после #11/#13) открываются сразу

+  `chat_id`/`message_id`, чтобы обновлять счётчик и отвечать «✅ восстановлено» на исходное сообщение.
+- **Сообщение**: тип, сервис, время, хвост лога (30 строк), кнопки «📜 Логи», «🩺 Статус», «📋 Список алертов».
+  Кнопки открывают экран новым сообщением, чтобы не затирать алерт.
+- **Список**: активные сверху, затем история за 7 дней, по 10 на страницу; 🛡 в общий список не попадает.
+- **Если Docker недоступен**, оцениваются только 🔌 и 💾: алерты контейнеров не закрываются вслепую.
+- **Краш при restart-политике**: контейнер поднимается за секунду и между раундами не виден в `exited` — поэтому
+  краш распознаётся и по росту `RestartCount` относительно предыдущего раунда; каждый новый — счётчик.
+- **Гистерезис**: алерт закрывается, когда условия нет `resolve_after` (60 с), а правки со счётчиком — не чаще раза
