+## Frontend e2e
+
+Для UI настроен Playwright-контур, который поднимает локальный стек:
+
+- `postgres` в отдельном Docker-контейнере;
+- `admin-api` и `mcp-server` через `cargo run`;
+- `apps/ui` через локальный Node static+proxy server для e2e;
+- `CRANK_DEMO_SEED=true` для предсказуемых demo-данных.
+
+Локальный запуск:
+
+```bash
+cd apps/ui
+npm ci
+npm run e2e:install
+npm run e2e
+```
+
+Или через `just`:

 ## Current
 
-### `feat/alpine-polish`
+### `feat/frontend-e2e`
 
-Status: in_progress
+Status: completed
 
 DoD:
-- Alpine UI pages have consistent feedback and shell state
-- Settings page exposes only honest live functionality and clearly marks deferred capabilities
-- Wizard live actions have stable loading and feedback behavior on real backend requests
-- Public UI routes use clean canonical paths instead of exposing `/html/...`
+- Playwright covers the core UI journeys against a real local stack
+- Frontend e2e can be run locally without manual environment setup
+- CI executes frontend e2e as a separate job and publishes failure artifacts
