 **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`).

+# Деплой бота
+
+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'
+```

+
+Ошибка health при деплое печатает команду; руками:
+
+```bash
+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.
