-# 🚀 Raspberry Pi Proje Dağıtım Rehberi (SSL Güncellemeli)
-
-Bu rehber, mevcut merkezi altyapıyı (Gitea, Runner, Central Database, Nginx) kullanarak yeni NestJS (Backend) ve Next.js (Frontend) projelerini nasıl ayağa kaldıracağını ve **SSL (HTTPS) sorunları yaşamadan** nasıl yayına alacağını adım adım açıklar.
-
----
-
-## 🏗 1. Altyapı Hazırlığı (Infrastructure)
-
-### A. Veritabanı Oluşturma
-Her yeni proje için merkezi PostgreSQL konteynerinde yeni bir veritabanı açılmalıdır.
-
-```bash
-# PROJE_ADI kısmını küçük harf ve boşluksuz yaz (örn: e_ticaret_db)
-docker exec -it backend_db createdb -U 'Rub1c0N-UseR.!' PROJE_ADI_db
-```
-
-### B. DNS Ayarları
-Domain panelinden (Cloudflare vb.) yeni subdomain'leri Raspberry Pi'nin dış IP'sine yönlendir:
-*   `api-proje.bilgich.com` -> **Raspberry Pi IP**
-*   `ui-proje.bilgich.com` -> **Raspberry Pi IP**
-
----
-
-## 🔐 2. Gitea Secret Ayarları
-
-**⚠️ Önemli:** Proje canlıya çıkarken SSL kullanacağımız için URL'leri şimdiden **https** olarak tanımlıyoruz.
-
-Gitea reponuzda **Settings > Actions > Secrets** yolunu izleyerek aşağıdaki anahtarları tanımlayın.
-
-### Backend İçin:
-
-| Key | Value Örneği | Açıklama |
-| :--- | :--- | :--- |
-| `DATABASE_URL` | `postgresql://Rub1c0N-UseR.%21:SIFRE%3D@backend_db:5432/PROJE_ADI_db?schema=public` | Özel karakterler encode edilmeli (!=%21, =%3D) |
-| `JWT_SECRET` | `rastgele_uzun_string` | Güvenlik anahtarı |
-
-### Frontend İçin:
-
-| Key | Value Örneği | Açıklama |
-| :--- | :--- | :--- |
-| `NEXT_PUBLIC_API_URL` | `https://api-proje.bilgich.com/api` | **https** olmasına dikkat et |
-| `NEXTAUTH_URL` | `https://ui-proje.bilgich.com` | **https** olmasına dikkat et |
-| `NEXTAUTH_SECRET` | `openssl_rand_base64_32_cikti` | Auth güvenliği için |
-
----
-
-## 🛠 3. Backend (NestJS) Proje Ayarları
-
-1.  **main.ts:** Global prefix ve Swagger yollarını kontrol et.
-2.  **Dockerfile:** Mevcut çalışan NestJS Dockerfile'ı kullan.
-3.  **deploy.yml Değişiklikleri:**
-    *   `--name backend-PROJE-container` (Her proje için unique isim)
-    *   `-p 150X:3000` (Sıradaki boş port: 1502, 1503...)
-    *   `--network gitea-server_gitea` (Database'e erişim için şart)
-
----
-
-## 🎨 4. Frontend (Next.js) Proje Ayarları
-
-1.  **next.config.js:** `output: 'standalone'` satırını ekle.
-2.  **Dockerfile:** `ARG` ve `ENV` satırlarına `NEXT_PUBLIC_` değişkenlerini ekle.
-3.  **deploy-ui.yml Değişiklikleri:**
-    *   `--build-arg` ile tüm Gitea secret'larını build aşamasına geç.
-    *   `--name ui-PROJE-container` (Unique isim)
-    *   `-p 180X:3000` (Sıradaki boş port: 1801, 1802...)
-    *   `-e NEXTAUTH_URL` ve `NEXTAUTH_SECRET` runtime değişkenlerini ekle.
-
----
-
-## 🚦 5. Nginx ve SSL Yönlendirmesi (KRİTİK ADIM)
-
-Diğer projelerle çakışma olmaması için her yeni domain'e mutlaka SSL kurulmalıdır.
-
-### A. Konfigürasyon Dosyası Oluştur
-Backend veya Frontend için dosya oluşturun:
-
-```bash
-sudo nano /etc/nginx/sites-available/proje-api
-# Veya
-sudo nano /etc/nginx/sites-available/proje-ui
-```
-
-### B. İçeriği Yapıştır (Sadece HTTP)
-İlk aşamada sadece 80 portunu dinleyen şu bloğu yapıştırın:
-
-```nginx
-server {
-    listen 80;
-    server_name api-proje.bilgich.com; # Domain adını buraya yaz
-
-    location / {
-        proxy_pass http://127.0.0.1:150X; # Uygulamanın dış portu (1502, 1802 vb.)
-        proxy_http_version 1.1;
-        proxy_set_header Upgrade $http_upgrade;
-        proxy_set_header Connection 'upgrade';
-        proxy_set_header Host $host;
-        proxy_cache_bypass $http_upgrade;
-        
-        # Gerçek IP Logları
-        proxy_set_header X-Real-IP $remote_addr;
-        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
-    }
-}
-```
-
-### C. Nginx'i Aktif Et
-Dosyayı `sites-enabled` klasörüne linkleyin ve Nginx'i reload edin:
-
-```bash
-sudo ln -s /etc/nginx/sites-available/proje-api /etc/nginx/sites-enabled/
-sudo nginx -t && sudo systemctl reload nginx
-```
-
-### D. SSL Sertifikası Kur (Certbot)
-Bu komut Nginx ayarlarını otomatik güncelleyip 443 portunu açacaktır. Bu adımı yapmazsanız HTTPS girişleri başka projelere yönlenir!
-
-```bash
-sudo certbot --nginx -d api-proje.bilgich.com
-```
-*Soru sorarsa "2" (Redirect) seçeneğini seçin.*
-
----
-
-## 💡 "Senior" İpuçları & Bakım
-
-### Port Yönetimi (Defteri Kebir)
-Kullandığın portları çakışmaması için mutlaka not et:
-*   **1501:** Digicraft BE
-*   **1502:** YeniProje BE
-*   **1800:** Digicraft UI
-*   **1801:** YeniProje UI
-
-### Disk Temizliği
-Raspberry Pi diski dolmaması için haftalık/aylık temizlik yap:
-```bash
-docker system prune -f
-```
-
-### Log Takibi
-Bir sorun olduğunda ilk buraya bak:
-```bash
-docker logs -f KONTEYNER_ADI
-```
-```

-# Learned Protocols & Standards
-
-This document serves as the persistent memory of the protocols, standards, and personas learned from the `skript-be` and `skript-ui` repositories.
-
-## 1. Frontend Standards (skript-ui)
-
-### Design & Aesthetics (`frontend-design`)
-- **Anti-AI Slop:** Avoid generic, cookie-cutter "AI" aesthetics (e.g., standard purple gradients, predictable layouts).
-- **Boldness:** Commit to a specific aesthetic direction (Minimalist, Brutalist, Magazine, etc.).
-- **Typography:** Use distinctive fonts; avoid system defaults like Arial/Inter unless intentional.
-- **Micro-interactions:** Prioritize one or two high-impact animations over scattered noise.
-- **Creativity:** Use noise textures, gradient meshes, asymmetry, and overlapping elements.
-
-### Architecture (`senior-frontend` & `nextjs-architecture-expert`)
-- **Next.js App Router:** STRICT adherence to App Router patterns (layouts, error.tsx, loading.tsx).
-- **Server Components (RSC):** Default to Server Components. Use Client Components ('use client') only when interactivity is required.
-- **State Management:** component-first thinking; use Context/Zustand for global state, local state for UI.
-- **Performance:** Aim for sub-3s load times. Use `next/image`, code splitting, and lazy loading.
-- **Tailwind CSS:** Use correctly; avoid long string pollution where possible (use utils/cva).
-
-### Quality Assurance (`senior-qa`)
-- **E2E Testing:** Critical flows must be tested.
-- **Coverage:** High unit test coverage for utilities and complex logic.
-
-## 2. Backend Standards (skript-be)
-
-### Code Quality (`code-reviewer`)
-- **Review:** Verify BEFORE implementing.
-- **Simplicity:** No over-engineering.
-- **Security:** No secrets in code. Input validation is mandatory.
-- **YAGNI:** "You Aren't Gonna Need It" - don't build features "just in case".
-
-### Security (`security-engineer` & `api-security-audit`)
-- **Zero Trust:** Verify every request.
-- **OWASP:** Check against Top 10 (Injection, Broken Auth, etc.).
-- **Data:** Validate all inputs using libraries (e.g., Zod, Joi).
-- **Logging:** Sanitize logs (no PII/secrets).
-
-### Database (`database-optimizer`)
-- **N+1:** Watch out for N+1 queries in loops/ORMs.
-- **Indexing:** Index foreign keys and search columns.
-- **Explain:** Check execution plans for complex queries.
-
-### General Engineering
-- **TypeScript:** Strict mode enabled. No `any`. Use generics and utility types (`typescript-pro`).
-- **Feedback:** "Receive Code Review" protocol – technical correctness > polite agreement. Verify suggestions before applying.
-
-### TypeScript Expertise (`typescript-pro`)
-- **Seniority:** I write *Senior-level* code. This means focusing on maintainability, scalability, and robustness, not just "making it work".
-- **Modern Techniques:** I utilize the latest TypeScript features:
-    - **Advanced Types:** Conditional types, Template Literal Types, Mapped Types.
-    - **Utility Types:** `Pick`, `Omit`, `Partial`, `Readonly`, `ReturnType`, `Parameters`, etc.
-    - **Generics:** Proper constraints (`T extends ...`) and defaults.
-    - **Type Inference:** Leveraging inference where clean, explicit typing where necessary for clarity.
-- **Strictness:**
-    - `noImplicitAny` is law.
-    - Avoid `any` at all costs; use `unknown` with type narrowing/guards if dynamic typing is truly needed.
-    - Strict null checks always on.
-- **Architecture:** Value objects, opaque types, and branded types for domain safety.
-
-## 3. Operational Protocols
-
-- **Agent Persona:** I act as the specific specialist required for the task (e.g., if debugging, I am `debugger`; if designing, I am `frontend-developer`).
-- **Proactiveness:** I do not wait for permission to fix obvious bugs or improve clear performace bottlenecks if they are within scope.
-- **Persistence:** These rules apply to ALL future tasks in this session.
