+- **Тесты**: `cd backend && .venv/bin/pytest`
+
+## Docker и CI/CD
+### Локальный запуск в Docker (приложение + PostgreSQL)
+```bash
+docker compose up --build
+```
+
+После старта:
+- UI/API: `http://localhost:8000`
+- PostgreSQL: `localhost:5432` (`postgres/postgres`, DB `ss_tools`)
+
+Остановить:
+```bash
+docker compose down
+```
+
+Полная очистка тома БД:
+```bash
+docker compose down -v
+```
+
+Если `postgres:16-alpine` не тянется из Docker Hub (TLS timeout), используйте fallback image:
+```bash
+POSTGRES_IMAGE=mirror.gcr.io/library/postgres:16-alpine docker compose up -d db
+```
+или:
+```bash
+POSTGRES_IMAGE=bitnami/postgresql:latest docker compose up -d db
+```
+Если на хосте уже занят `5432`, поднимайте Postgres на другом порту:
+```bash
+POSTGRES_HOST_PORT=5433 docker compose up -d db
+```
+
+### Миграция legacy-данных в PostgreSQL
+Если нужно перенести старые данные из `tasks.db`/`config.json`:
+```bash
+cd backend
+PYTHONPATH=. .venv/bin/python src/scripts/migrate_sqlite_to_postgres.py --sqlite-path tasks.db
+```
+
+### CI/CD
+Добавлен workflow: `.github/workflows/ci-cd.yml`
+- backend smoke tests
+- frontend build
+- docker build
+- push образа в GHCR на `main/master`
+
+## Контакты и вклад

 The settings page is located at `frontend/src/pages/Settings.svelte`. It provides forms for managing global settings and Superset environments.
 
+## Reports Center
+
+Unified reports are available at [`/reports`](frontend/src/routes/reports/+page.svelte) and use the backend API at [`/api/reports`](backend/src/api/routes/reports.py) and [`/api/reports/{report_id}`](backend/src/api/routes/reports.py).
+
+### What operators can do
+
+- View all task outcomes (LLM verification, backup, migration, documentation) in one list.
+- Filter by type and status.
+- Open report detail with diagnostics and recommended next actions.
+- Continue working even for unknown task types and partial payloads (explicit placeholders are shown instead of hidden data).
+
+### Troubleshooting
+
+- If report list is empty, verify tasks exist and clear filters.
+- If report detail is not found (404), confirm the selected report still exists in task history.
+- If report API tests fail during local execution with database connectivity errors, ensure the configured DB is reachable or run in an environment with available test DB services.
