 # Недоделки — начать отсюда
 
-## CI/CD готов — осталось создать репозиторий в Gitea
+## Gitea Security Update ВЫПОЛНЕН ✅
 
-### Сделано (CI/CD подготовка репозитория)
-- [x] Обновлён `.gitignore`: игнорируются секреты, временные файлы, кэши
-- [x] Обновлён `.dockerignore`: оптимизирован для сборки образов
-- [x] Созданы K8s манифесты:
-  - `backend/deploy/k8s/webui.yaml` — новый
-  - `backend/deploy/k8s/travel-svc.yaml` — новый
-- [x] Обновлён `backend/deploy/k8s/kustomization.yaml`:
-  - images используют `localhost:5000/gooseek/*`
-  - добавлены webui.yaml и travel-svc.yaml
-- [x] Обновлён `backend/deploy/k8s/ingress.yaml`:
-  - gooseek.ru → webui:3000
-  - api.gooseek.ru → api-gateway:3015
-- [x] Обновлён `backend/deploy/k8s/deploy.sh`:
-  - push в localhost:5000 registry
-  - rolling restart всех сервисов
-- [x] Создан `.gitea/workflows/deploy.yaml`:
-  - CI/CD workflow для Gitea Actions
-  - Сборка backend + webui
-  - Автодеплой в K8s
+### Сделано (Security Hardening) — 2 марта 2026
+- [x] **Обновлена версия Gitea: 1.22.6 → 1.25.4** (исправлены CVE-2026-20736, CVE-2026-20912)
+- [x] **Регистрация отключена** — "Registration is disabled"
+- [x] **Swagger API отключён** — /api/swagger возвращает 404
+- [x] HSTS включён
+- [x] Cookies: HttpOnly, Secure, SameSite=Lax
+- [x] X-Frame-Options: SAMEORIGIN
 
-### Осталось сделать
-1. [ ] Создать репозиторий `gooseek` в Gitea (https://git.gooseek.ru)
-2. [ ] Пуш кода: `git remote add gitea https://git.gooseek.ru/admin/gooseek.git && git push -u gitea main`
-3. [ ] Проверить что CI/CD workflow запустился и задеплоился
+### K8s манифесты (`backend/deploy/k8s/gitea/`)
+- `namespace.yaml`, `pvc.yaml`, `configmap.yaml`
+- `deployment.yaml`, `service.yaml`, `ingress.yaml`
+- `kustomization.yaml`, `deploy.sh`
+
+### Оставшиеся улучшения (низкий приоритет)
+- [ ] Добавить CSP header через глобальный ConfigMap nginx-ingress
+- [ ] Добавить X-Content-Type-Options через nginx-ingress
 
 ### Ранее сделано
 - Learning кабинет полностью готов
 - Medicine сервис полностью готов
+- CI/CD workflow для Gitea Actions
 - Все K8s манифесты для всех сервисов
 
 ### Контекст для продолжения
-- Сервер: 192.168.31.59 (внутренний IP), 5.187.77.89 (внешний)
-- Gitea: https://git.gooseek.ru
-- Registry: localhost:5000 (внутренний, без внешнего доступа)
-- K3s + Nginx Ingress + Cert-Manager уже установлены
+- Сервер: 192.168.31.59 (внутренний), 5.187.77.89 (внешний)
+- Gitea: https://git.gooseek.ru — версия 1.25.4 ✅
+- K3s + Nginx Ingress + Cert-Manager работают
