feat(runner): tgit-runner — сервисы в песочнице на хосте, деплой после push (#13)

- infra/runner/tgit-runner: deploy/restart/remove/list по SSH forced command;
  аргументы не исполняются и не глобятся; архив — только файлы и папки,
  без «..», ≤ 20 МБ, есть main.py; health_url — только localhost
- песочница: uid 10001, read-only, tmpfs noexec, cap-drop ALL,
  no-new-privileges, 128 МБ без swap, 0.25 CPU, 64 PID, --network none
  (сеть — только по egress-allow админа), лимит 10 сервисов, 2 образа
- новая версия стартует рядом (-next) и заменяет старую, только став
  healthy; иначе удаляется, старая работает, exit 3
- бот: после push git archive изменённых services/<name>/ → runner;
  автору — «🚀 работает» или «⛔ не развёрнут» с логом, команде — алерт ⛔;
  удалённая папка → remove; «♻️ Перезапустить» в «Статусе» для админа (S-5)
- examples/escape_attempts: все попытки выбраться — BLOCKED на живом Docker
- install.sh, authorized_keys.example; CD бота обновляет runner на хосте

+---
+
+## 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 |
+| **🚀 Деплой сервисов** | после push бот отправляет изменённые `services/<name>/` в `tgit-runner` на хосте: сборка образа, запуск в песочнице (uid 10001, read-only, без capabilities и сети, 128 МБ / 0.25 CPU / 64 процесса); старая версия заменяется только здоровой новой, иначе ⛔ с логом; «♻️ Перезапустить» в «Статусе» для админа | #13, S-5 |
+| **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` |
+| SSH → `tgit-runner` | деплой и перезапуск сервисов на хосте | `ssh` подпроцессом, ключ с forced command |
+| 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):
+- проверки CI репозитория загрузок (ruff, bandit, тесты) перед деплоем: сейчас бот разворачивает сервис сразу после
+  push, проверив только синтаксис; ожидание зелёного CI появится вместе с #11;
+- 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.

+- **Краш при restart-политике**: контейнер поднимается за секунду и между раундами не виден в `exited` — поэтому

 **Последствия:** два LLM-вызова на запрос (латентность, токены → квота 30/сутки); даже при обходе стража вред ограничен схемой `LogQuery`.

+## ADR-014: Связь «прогон ↔ коммит» — через куб `meta`, печатающий sha
+**Дата:** 2026-10-14 · **Статус:** принято (уточняет ADR-003)
+
+**Контекст:** бот должен понять, какой прогон CI относится к его пушу. В API SourceCraft у прогона нет sha коммита (ни в списке, ни в деталях), фильтра по коммиту нет; логи служебных кубов (`#git-clone`) API не отдаёт.
+**Решение:** первый куб задачи `check` в `tgit-uploads` — `meta`: `echo "TGIT_COMMIT_SHA=$SOURCECRAFT_COMMIT_SHA"`. Бот читает его лог (`SourceCraftClient.run_commit_sha`) и сопоставляет прогон с пушем.
+**Альтернативы:** запускать CI из бота вручную (`POST /cicd/runs` с `head.commit`) — номер прогона известен сразу, но push-триггер пришлось бы убрать, и ручные пуши в репозиторий остались бы без CI; сопоставление по времени — ломается при параллельных пушах.
+**Последствия:** +1 короткий куб на прогон; куб `meta` нельзя удалять или переименовывать (он в `.sourcecraft/`, который бот защищает от правок); прогоны старше этого решения sha не имеют.
+
+## ADR-015: CI/CD бота — на Gitea Actions (как в Vobot)
+**Дата:** 2026-10-16 · **Статус:** принято (меняет ADR-010 в части CI/CD бота)
+
+**Контекст:** SourceCraft отложен: ключ бота там не принимается, триггеры зависят от основной ветки, раннеры с очередью до минут. Гейт и деплой нужны сейчас.
+**Решение:** CI (`.gitea/workflows/ci.yml`: ruff, mypy, миграции на Postgres, pytest) и CD (`.gitea/workflows/deploy.yml` → `infra/deploy/deploy.sh`) — на Gitea Actions, как у Vobot и meditron, на общих раннерах Gitea. Деплой — на хост Vobot, `dev`/`prod` по веткам, через пользователя `tgit-deploy`. Репозиторий загрузок на сервере — временно `HSE/tgit-uploads` в Gitea.
+**Альтернативы:** ждать SourceCraft — блокирует проверку и демо.
+**Последствия:** `.sourcecraft/ci.yaml` бота остаётся для будущего возврата; при возврате к SourceCraft меняются `GIT_UPLOADS_URL` и ключ, код не трогаем. На RF-сервере Telegram — только через прокси (`TELEGRAM_PROXY_URL`).

+CD — `.gitea/workflows/deploy.yml` (Gitea Actions, ADR-015): push в `dev` → окружение **dev**, push в `main` → **prod**.
+Под капотом — `infra/deploy/deploy.sh`, тот же скрипт работает руками и для любого Docker-хоста.
+
+## Сервер (хост Vobot, 72.56.247.166)
+
+| Что | Где |
+|---|---|
+| Пользователь | `tgit-deploy` (группа `docker`), ключ CI в `~/.ssh/authorized_keys` |
+| Окружение | `/srv/tgit/<env>/` — `.env` (только здесь, 600), `app/` (текущий релиз), `app.old/` (предыдущий), `REVISION` |
+| Контейнеры | Compose-проект `tgit-<env>`: `tgit-<env>-bot-1`, `tgit-<env>-postgres-1`; volumes `pgdata`, `uploads` |
+| Telegram | с сервера напрямую недоступен → `TELEGRAM_PROXY_URL` (тот же прокси, что у meditron) |
+| Репозиторий загрузок | временно `ssh://git@gitea.24studbank.ru:2222/HSE/tgit-uploads.git`, deploy key бота с записью |
+
+Секреты репозитория в Gitea (Settings → Actions → Secrets): `DEPLOY_SSH_KEY` (приватный ключ `tgit-cd@gitea`), `DEPLOY_HOST` (`tgit-deploy@72.56.247.166`).
+
+## Руками
+
+```bash
+DEPLOY_SSH_OPTS="-F /dev/null -i ~/.ssh/tgit_ci_deploy -o IdentitiesOnly=yes" infra/deploy/deploy.sh dev HEAD
+```
+
+Другой сервер: `DEPLOY_HOST=user@host`, на нём — Docker, пользователь в группе `docker`, `/srv/tgit/<env>/.env`.
+
+## Проверить

+```bash
+ssh tgit-deploy@72.56.247.166 'cat /srv/tgit/dev/REVISION; docker ps --filter name=tgit-dev; docker logs --tail 20 tgit-dev-bot-1'

+ssh tgit-deploy@72.56.247.166
+cd /srv/tgit/dev && rm -rf app && mv app.old app && cd app && docker compose -p tgit-dev up -d --build
+```
+
+## Завести prod
+
+Нужен **отдельный токен бота** (один токен — один процесс polling): создать бота у @BotFather →
+`/srv/tgit/prod/.env` по образцу dev (`TELEGRAM_BOT_TOKEN`, `ADMIN_IDS`, `POSTGRES_PASSWORD`, `GIT_UPLOADS_URL`,
+`GIT_SSH_KEY_B64`, `TELEGRAM_PROXY_URL`, `LLM_PROVIDER`). Пока файла нет, деплой `main` пропускается.

+# infra/runner — `tgit-runner`
+
+Запуск сервисов из репозитория загрузок (`services/<name>/`) на хосте в песочнице — ADR-005, ADR-006,
+[ARCHITECTURE §4](../../docs/ARCHITECTURE.md).
+
+```
+бот: push ─► git archive <sha>:services/<name> ─► ssh tgit-deploy@host deploy <name> <sha>  (архив — в stdin)
+                                                    │ forced command: только tgit-runner
+host: tgit-runner ─► проверка аргументов и архива ─► docker build ─► docker run …-next (песочница)
+                  ─► healthy за 60 с? ─► да: заменить старый контейнер · нет: удалить новый, старый работает, exit 3
+```
+
+| Команда | Что делает |
+|---|---|
+| `deploy <service> <sha>` | собрать образ `tgit-svc-<service>:<sha>` и запустить, старый заменяется только здоровым новым |
+| `restart <service>` | перезапуск (кнопка «♻️ Перезапустить» в «Статусе», только админ) |
+| `remove <service>` | сервис удалён из репозитория — остановить и удалить образы |
+| `list` | контейнеры сервисов |
+
+**Песочница:** uid 10001, read-only FS, `/tmp` — tmpfs 16 МБ с `noexec`, `--cap-drop ALL`, `no-new-privileges`,
+128 МБ без swap, 0.25 CPU, 64 процесса, `--network none` (интернет — только если `network: true` в `tgit.yaml`
+**и** имя сервиса есть в `/srv/tgit/runner/egress-allow`), без Docker-сокета, `--restart on-failure:3`, ротация логов.
+Не больше 10 сервисов на хост; хранятся два последних образа сервиса.
+
+**Проверено** [`examples/escape_attempts`](../../examples/escape_attempts/): запись в код и `/etc`, сеть, DNS,
+docker.sock, `setuid(0)`, raw-сокет, 200 процессов, запуск из `/tmp` — всё `BLOCKED`.
+
+**Установка** (один раз, root на хосте):
+
+```bash
+ssh-keygen -t ed25519 -N '' -C tgit-runner -f tgit-runner-key      # ключ бота для раннера
+sudo infra/runner/install.sh tgit-runner-key.pub tgit-deploy
+# в .env бота на сервере:
+#   RUNNER_HOST=host.docker.internal   RUNNER_SSH_KEY_B64=$(base64 -w0 tgit-runner-key)
+```
+
+Дальше скрипт обновляется сам: деплой бота (`infra/deploy/remote.sh`) копирует свежий `tgit-runner`, если раннер
+установлен. Тесты — `tests/runner/` (фейковые `docker` и `ssh`, сам скрипт настоящий).
