+### Операционный workflow (CLI/API/TUI)
+
+#### 1) Headless flow через CLI (рекомендуется для CI/CD)
+
+```bash
+cd backend
+
+# 1. Регистрация кандидата
+.venv/bin/python3 -m src.scripts.clean_release_cli candidate-register \
+  --candidate-id 2026.03.09-rc1 \

+.venv/bin/python3 -m src.scripts.clean_release_cli compliance-run \
+  --candidate-id 2026.03.09-rc1 \
+  --actor release-operator
+```
+
+#### 2) API flow (автоматизация через сервисы)
+
+- V2 candidate/artifact/manifest API:
+  - `POST /api/clean-release/candidates`
+  - `POST /api/clean-release/candidates/{candidate_id}/artifacts`
+  - `POST /api/clean-release/candidates/{candidate_id}/manifests`
+  - `GET /api/clean-release/candidates/{candidate_id}/overview`
+- Legacy compatibility API (оставлены для миграции клиентов):
+  - `POST /api/clean-release/candidates/prepare`
+  - `POST /api/clean-release/checks`
+  - `GET /api/clean-release/checks/{check_run_id}`
+
+#### 3) TUI flow (тонкий клиент поверх facade)
 
 ```bash
 cd /home/busya/dev/ss-tools
-./backend/.venv/bin/python3 -m backend.src.scripts.clean_release_tui
+./run_clean_tui.sh 2026.03.09-rc1
 ```
 
+Горячие клавиши:
+- `F5`: Run Compliance
+- `F6`: Build Manifest
+- `F7`: Reset Draft
+- `F8`: Approve
+- `F9`: Publish
+- `F10`: Refresh Overview
+
+Важно: TUI требует валидный TTY. Без TTY запуск отклоняется с инструкцией использовать CLI/API.
