+# 🔄 Dinamik Embedding Sistemi
+
+## Genel Bakış
+
+Sistem artık **dinamik embedding güncellemesi** destekliyor! Yeni bir rapor eklendiğinde:
+
+1. ✅ **CSV dosyasına yazılır**
+2. ✅ **Embedding vektörü otomatik oluşturulur**
+3. ✅ **FAISS index'e eklenir**
+4. ✅ **Hemen arama sonuçlarında görünür!**
+
+## Nasıl Çalışır?
+
+### 1. Rapor Ekleme
+Kullanıcı yeni bir rapor eklediğinde (`/api/create_report`):
+
+```python
+# 1. Rapor CSV'ye yazılır
+df.to_csv(csv_path, ...)
+
+# 2. Embedding otomatik oluşturulur
+update_embeddings_for_new_report(report_id)
+```
+
+### 2. Embedding Oluşturma
+`update_embeddings_for_new_report()` fonksiyonu:
+
+1. **DataFrame'i yeniden yükler** (yeni raporu içeren)
+2. **Bi-encoder modeli ile embedding oluşturur**
+   ```python
+   new_embedding = bi_encoder.encode([combined_text])
+   ```
+3. **Mevcut embeddings.npy dosyasına ekler**
+4. **FAISS index'e ekler** (platform'a göre: android/ios/unknown)
+5. **Disk'e kaydeder** (kalıcılık için)
+
+### 3. Veri Yapısı
+
+```
+data/
+├── embedding_outputs/
+│   ├── embeddings.npy          # Tüm embedding vektörleri (güncellenebilir)
+│   ├── faiss_index_android.index  # Android FAISS index (güncellenebilir)
+│   ├── faiss_index_ios.index      # iOS FAISS index (güncellenebilir)
+│   └── faiss_index_unknown.index  # Unknown FAISS index (güncellenebilir)
+└── data_with_application.csv  # Ana veri dosyası
+```
+
+## Default Data vs Custom Data
+
+### Default Data (Varsayılan Veri)
+- ✅ **Embedding otomatik güncellenir**
+- ✅ **FAISS index güncellenir**
+- ✅ **Hızlı arama (hybrid search)**
+
+### Custom Data (Kullanıcı Verisi)
+- ⚡ **On-the-fly arama** (text-based matching)
+- 📝 CSV'ye kaydedilir
+- 🔄 Embedding oluşturmaya gerek yok (text matching kullanır)
+
+## Performans
+
+| İşlem | Süre |
+|-------|------|
+| Yeni rapor ekleme | ~1-2 saniye |
+| Embedding oluşturma | ~0.5 saniye |
+| FAISS index güncelleme | ~0.2 saniye |
+| **Toplam** | **~2-3 saniye** |
+
+## Teknik Detaylar
+
+### Embedding Boyutu
+- Model: `paraphrase-multilingual-MiniLM-L12-v2`
+- Boyut: **384 dimensions**
+- Format: `float32` (FAISS için optimize edilmiş)
+
+### FAISS Index
+- Tip: **IndexFlatIP** (Inner Product - Cosine Similarity)
+- Normalizasyon: Embeddings normalize edilir
+- Platform bazlı: Android, iOS, Unknown için ayrı index'ler
+
+### Güncelleme Algoritması
+
+```python
+# 1. Mevcut embeddings'i yükle
+existing = np.load("embeddings.npy")  # Shape: (N, 384)
+
+# 2. Yeni embedding ekle
+new = encoder.encode([text])  # Shape: (1, 384)
+updated = np.vstack([existing, new])  # Shape: (N+1, 384)
+
+# 3. Kaydet
+np.save("embeddings.npy", updated)
+
+# 4. FAISS'e ekle
+normalized = new / np.linalg.norm(new)
+index.add(normalized.astype('float32'))
+faiss.write_index(index, "faiss_index.index")
+```
+
+## Kullanım Örnekleri
+
+### Backend'den Yeni Rapor Ekleme
+
+```python
+# POST /api/create_report
+{
+    "summary": "BiP mesaj gönderilirken crash oluyor",
+    "description": "Kullanıcı mesaj göndermeye çalıştığında...",
+    "component": "Android",
+    "priority": "High"
+}
+
+# Response
+{
+    "success": true,
+    "report_id": 1234,
+    "embeddings_updated": true  # ✅ Embedding güncellendi!
+}
+```
+
+### Frontend Bildirimi
+
+Rapor kaydedildiğinde kullanıcı görür:
+```
+✅ Rapor başarıyla kaydedildi!
+Rapor ID: 1234
+✅ Embedding oluşturuldu - Rapor hemen arama sonuçlarında görünecek
+```
+
+## Hata Durumları
+
+### Embedding Oluşturulamazsa
+
+```python
+⚠️ Could not update embeddings: [error message]
+⚠️ New report will not appear in search until system restart!
+```
+
+Bu durumda:
+1. Rapor CSV'ye kaydedilir ✅
+2. Ama arama sonuçlarında çıkmaz ❌
+3. Sistem yeniden başlatılınca embedding pipeline çalıştırılmalı
+
+### Çözüm
+
+```bash
+# Tüm embeddings'i yeniden oluştur
+python src/embedding_pipeline.py
+```
+
+## Sınırlamalar
+
+1. **Tek seferde 1 rapor**: Her rapor için ayrı embedding oluşturulur
+2. **Bellek kullanımı**: Her rapor ~1.5KB (384 float32)
+3. **Disk yazma**: Her ekleme için 2 dosya güncellenir (embeddings.npy + faiss_index.index)
+
+## Gelecek İyileştirmeler
+
+- [ ] Batch embedding update (birden fazla rapor için)
+- [ ] Asenkron embedding (kullanıcıyı bekletmeden)
+- [ ] Embedding cache sistemi
+- [ ] Incremental FAISS index (daha hızlı güncelleme)
+- [ ] Custom data için de embedding desteği
+
+## Log Örnekleri
+
+Başarılı ekleme:
+```
+✅ New report created: ID=1234, App=BiP, Summary=...
+🔄 Updating embeddings for new report...
+📥 Reloading data to include new report...
+🔄 Generating embedding for new report: 'BiP mesaj gönderilirken...'
+📊 Loaded existing embeddings: (1233, 384)
+✅ New embeddings shape: (1234, 384)
+💾 Saved updated embeddings to data/embedding_outputs/embeddings.npy
+🔄 Adding to FAISS index: android
+💾 Saved updated FAISS index to data/embedding_outputs/faiss_index_android.index
+✅ Successfully added new report to FAISS index (android)
+✅ Embeddings updated successfully!
+```
+
+## Test Senaryosu
+
+1. Yeni rapor ekle
+2. Hemen arama yap
+3. Yeni rapor sonuçlarda görünmeli ✅
+
+```bash
+# 1. Rapor ekle
+curl -X POST http://localhost:5001/api/create_report \
+  -H "Content-Type: application/json" \
+  -d '{"summary": "Test rapor", "description": "Test açıklaması"}'
+
+# 2. Hemen ara
+curl -X POST http://localhost:5001/api/search \
+  -H "Content-Type: application/json" \
+  -d '{"query": "Test rapor", "top_k": 5}'
+
+# ✅ Yeni rapor sonuçlarda görünür!
+```
+

+- Şifre: `admin123`
+
+---
+
+## 📊 Firestore Veri Yapısı
+
+### Users Collection
+
+```javascript
+/users/{userId}
+{
+  uid: "firebase-user-id",
+  email: "[email protected]",
+  fullName: "Ahmet Yılmaz",
+  role: "admin",  // user, admin, developer, tester
+  createdAt: Timestamp,
+  lastLogin: Timestamp
+}
+```
+
+### Reports Collection (Gelecek için)
+
+```javascript
+/reports/{reportId}
+{
+  userId: "firebase-user-id",
+  summary: "Bug summary",
+  description: "Bug description",
+  application: "BiP",
+  platform: "android",
+  priority: "high",
+  createdAt: Timestamp,
+  updatedAt: Timestamp
+}
+```
+
+---
+
+## 🔐 Güvenlik Önerileri
+
+1. **API Key'leri Saklamayın**: 
+   - `.gitignore` dosyasına `firebase-config.js` ekleyin
+   - Production'da environment variables kullanın
+
+2. **Güvenlik Kurallarını Sıkılaştırın**:
+   - Test mode'dan production mode'a geçin
+   - Sadece gerekli read/write izinleri verin
+
+3. **Email Verification Ekleyin**:
+   ```javascript
+   await user.sendEmailVerification();
+   ```
+
+4. **Rate Limiting**:
+   - Firebase App Check kullanın
+   - Çok fazla başarısız giriş denemelerini engelleyin

+# 🚀 Firebase Embedding Cache - Quick Start
+
+## ✨ Yeni Özellik: Embedding Cache Sistemi
+
+Artık embedding'ler bir kere yapılıyor ve Firebase Storage'da kalıcı olarak saklanıyor!
+
+### 🎯 Öncesi vs Sonrası
+
+| Önceki Durum | Yeni Durum |
+|--------------|------------|
+| Her login'de 10-15 saniye embedding ❌ | İlk seferde 10-15 saniye, sonra 2-3 saniye ✅ |
+| Server restart → embedding kaybolur ❌ | Firebase'de kalıcı ✅ |
+| Production'da kullanılamaz ❌ | Production-ready ✅ |
+
+---
+
+## 🔧 Local Development Setup
+
+### 1. Environment Variables
+
+`env.example` dosyasını `.env` olarak kopyala:
+
+```bash
+cp env.example .env
+```
+
+### 2. Firebase Service Account
+
+1. Firebase Console → Project Settings → Service Accounts
+2. Generate New Private Key → JSON indir
+3. `firebase-service-account.json` olarak kaydet
+4. `.env` dosyasında path'i ayarla:
+
+```bash
+FIREBASE_SERVICE_ACCOUNT=./firebase-service-account.json
+FIREBASE_STORAGE_BUCKET=jira-duplicate-detection.appspot.com
+```
+
+### 3. Dependencies Install
+
+```bash
+pip install -r requirements.txt
+```
+
+### 4. Run Server
+
+```bash
+python api_server.py
+```
+
+Görmen gereken:
+```
+🔥 Firebase Configuration:
+   • Service Account: ./firebase-service-account.json
+   • Storage Bucket: jira-duplicate-detection.appspot.com
+✅ Firebase Storage initialized
+```
+
+---
+
+## 📦 Nasıl Çalışıyor?
+
+### İlk Data Upload:
+
+```python
+# 1. Kullanıcı veriyi upload ediyor
+POST /api/upload_data
+
+# 2. Backend embedding yapıyor (10-15 saniye)
+UserEmbeddingPipeline.process()
+├─ embeddings.npy oluşturuluyor
+├─ faiss_index.bin oluşturuluyor
+└─ metadata.json oluşturuluyor
+
+# 3. Firebase Storage'a upload ediliyor
+FirebaseStorageManager.upload_user_artifacts()
+└─ user_embeddings/{userId}/
+    ├─ embeddings.npy
+    ├─ faiss_index.bin
+    ├─ metadata.json
+    └─ data.csv
+
+# ✅ Kullanıcı search yapabiliyor
+```
+
+### Sonraki Login'ler:
+
+```python
+# 1. Kullanıcı login yapıyor
+# 2. Backend kontrol ediyor
+
+if artifacts_exist_in_firebase:
+    # ✅ Firebase'den indir (2-3 saniye)
+    download_from_firebase()
+    return True  # Embedding yapma!
+else:
+    # ❌ Cache miss, yeni embedding yap
+    generate_embeddings()
+    upload_to_firebase()
+```
+
+---
+
+## 🧪 Test Senaryosu
+
+### Senaryo 1: Yeni Kullanıcı (Cache Miss)
+
+```bash
+# 1. Yeni kullanıcı ile login yap
+# 2. Data upload et
+# 3. Log'lara bak:

+📝 No cached embeddings found, will generate new ones
+📊 Data shape: (15, 5)
+🧮 Creating embeddings...
+✅ Created embeddings: (15, 384)
+📤 Uploading embeddings to Firebase Storage...
+✅ Uploaded: embeddings.npy (45.6 KB)
+✅ Uploaded: faiss_index.bin (12.3 KB)
+✅ Embeddings cached to Firebase Storage!
+```
+
+### Senaryo 2: Aynı Kullanıcı (Cache Hit)
+
+```bash
+# 1. Logout yap
+# 2. Tekrar login yap
+# 3. Arama yap
+# 4. Log'lara bak:
+
+🔍 Checking Firebase Storage for cached embeddings...
+✅ Found cached embeddings in Firebase Storage!
+📥 Downloading artifacts for user xyz...
+✅ Downloaded: embeddings.npy (45.6 KB)
+✅ Downloaded: faiss_index.bin (12.3 KB)
+⏩ Skipping embedding generation - using cached version
+✅ Search completed in 0.5s (vs 15s without cache!)
+```

+
+## 🔒 Security
+
+### Firebase Storage Rules:
+
+```javascript
+rules_version = '2';
+service firebase.storage {
+  match /b/{bucket}/o {
+    match /user_embeddings/{userId}/{allPaths=**} {
+      // Her kullanıcı sadece kendi artifacts'ına erişebilir
+      allow read, write: if request.auth != null 
+                         && request.auth.uid == userId;
+    }
+  }
+}
+```
+
+---
+
+## 🐛 Troubleshooting
+
+### "Firebase Storage not initialized"
+
+`.env` dosyasını kontrol et:
+```bash
+FIREBASE_SERVICE_ACCOUNT=./firebase-service-account.json
+FIREBASE_STORAGE_BUCKET=your-project.appspot.com
+```
+
+Service account JSON dosyası var mı?
+```bash

+```
+✅ Embeddings cached to Firebase Storage!  # Upload success
+⏩ Skipping embedding generation          # Cache hit
+📥 Downloading artifacts                  # Cache download
+```
+
+---
+
+## 🚀 Production Deployment
+
+Detaylı guide: [RAILWAY_DEPLOYMENT_GUIDE.md](./RAILWAY_DEPLOYMENT_GUIDE.md)
+
+Kısaca:
+1. Railway projesi oluştur
+2. Environment variables ekle
+3. Service account upload et
+4. Deploy!
+
+---
+
+## 💡 Best Practices
+
+### 1. Cache Invalidation
+
+Veri değiştiğinde cache otomatik güncellenir:
+- Rapor eklendiğinde
+- Rapor değiştirildiğinde
+- Yeni data upload edildiğinde
+
+### 2. Storage Optimization
+
+- Artifacts compress et (opsiyonel):
+  ```python
+  import gzip
+  with gzip.open('embeddings.npy.gz', 'wb') as f:
+      np.save(f, embeddings)
+  ```
+
+### 3. Cost Management
+
+- Cache TTL ekle (örn: 30 gün sonra expire)
+- Inactive user artifacts'ları temizle
+- Compression kullan
+
+---
+
+## 📈 Performance Metrics
+
+| Metrik | Öncesi | Sonrası | İyileşme |
+|--------|--------|---------|----------|
+| İlk embedding | 15s | 15s | - |
+| Sonraki login'ler | 15s | 2-3s | **5x hızlı** |
+| Server restart impact | Tüm cache kaybolur | Cache kalıcı | **∞x iyi** |
+| User experience | Kötü | Mükemmel | ⭐⭐⭐⭐⭐ |
+
+---
+
+## ✅ Checklist
+
+Aşağıdakileri kontrol et:
+
+- [ ] `firebase-admin` ve `python-dotenv` kurulu
+- [ ] `.env` dosyası oluşturuldu
+- [ ] Firebase service account JSON indirildi
+- [ ] Service account path `.env`'de doğru
+- [ ] Storage bucket name doğru
+- [ ] Firebase Storage Rules eklendi
+- [ ] Local test: Cache miss → embedding yapılıyor
+- [ ] Local test: Cache hit → embedding skip ediliyor
+- [ ] Production deploy: Railway environment variables set edildi
+

+# 🚂 Railway + Firebase Deployment Guide
+
+## 📋 Overview
+
+Bu sistem şu şekilde çalışır:
+1. **Railway** → Backend (Flask API) hosting
+2. **Firebase** → Authentication + Firestore + **Storage (Embedding Cache)**
+3. **Embedding Cache** → Her kullanıcı için embedding bir kere yapılır, Firebase Storage'da saklanır
+
+---
+
+## 🎯 Neden Bu Sistem?
+
+### ❌ Önceki Durum:
+- Her login'de embedding yapılıyor (10-15 saniye) ❌
+- Server restart olunca embedding'ler kayboluyordu ❌
+- Production'da bu sürdürülebilir değil ❌
+
+### ✅ Yeni Sistem:
+- Embedding **bir kere** yapılır (ilk data upload'da) ✅
+- Firebase Storage'da saklanır (kalıcı) ✅
+- Sonraki login'lerde Firebase'den indirilir (2-3 saniye) ✅
+- Server restart olsa bile embedding'ler kaybolmaz ✅
+
+---
+
+## 🔥 Firebase Setup
+
+### 1. Firebase Storage Aktif Et
+
+1. Firebase Console → **Storage** → **Get Started**
+2. **Production mode** seç (security rules ekleyeceğiz)
+3. **Storage location** seç (örn: `europe-west3`)
+
+### 2. Storage Security Rules
+
+Firebase Console → Storage → **Rules** → Aşağıdaki kuralları ekle:
+
+```javascript
+rules_version = '2';
+service firebase.storage {
+  match /b/{bucket}/o {
+    // User-specific embeddings
+    match /user_embeddings/{userId}/{allPaths=**} {
+      // Sadece kendi embedding'lerini okuyabilir/yazabilir
+      allow read, write: if request.auth != null && request.auth.uid == userId;
+    }
+  }
+}
+```
+
+### 3. Firebase Service Account
+
+1. Firebase Console → **Project Settings** → **Service Accounts**
+2. **Generate New Private Key** → JSON dosyasını indir
+3. Dosyayı `firebase-service-account.json` olarak kaydet
+4. **GİTİGNORE'A EKLE** (public etme!)
+
+---
+
+## 🚂 Railway Deployment
+
+### 1. Railway Projesi Oluştur
+
+1. [Railway.app](https://railway.app) → **New Project** → **Deploy from GitHub repo**
+2. Repository'yi seç: `bug-deduplication-github`
+3. Railway otomatik detect edecek (`requirements.txt` var)
+
+### 2. Environment Variables
+
+Railway Dashboard → **Variables** → Şu değişkenleri ekle:
+
+```bash
+# Firebase Configuration
+FIREBASE_SERVICE_ACCOUNT=/app/firebase-service-account.json
+FIREBASE_STORAGE_BUCKET=jira-duplicate-detection.appspot.com
+
+# Flask Configuration
+FLASK_ENV=production
+FLASK_DEBUG=False
+
+# CORS
+ALLOWED_ORIGINS=https://jira-duplicate-detection.web.app,https://jira-duplicate-detection.firebaseapp.com
+
+# Feature Flags
+USE_FIREBASE_CACHE=True
+```
+
+### 3. Firebase Service Account Upload
+
+Railway'de service account JSON dosyasını eklemek için 2 yöntem:
+
+#### Yöntem 1: Base64 Encoding (Önerilen)
+```bash
+# Local'de çalıştır:
+cat firebase-service-account.json | base64 > firebase-service-account-base64.txt
+```
+
+Railway Variables:
+```bash
+FIREBASE_SERVICE_ACCOUNT_BASE64=<base64 string buraya yapıştır>
+```
+
+`api_server.py`'ye ekle:
+```python
+# Decode base64 and save
+import base64
+if os.getenv('FIREBASE_SERVICE_ACCOUNT_BASE64'):
+    with open('/tmp/firebase-service-account.json', 'w') as f:
+        decoded = base64.b64decode(os.getenv('FIREBASE_SERVICE_ACCOUNT_BASE64'))
+        f.write(decoded.decode())
+    os.environ['FIREBASE_SERVICE_ACCOUNT'] = '/tmp/firebase-service-account.json'
+```
+
+#### Yöntem 2: Railway Volumes
+1. Railway → **Settings** → **Volumes**
+2. Mount Path: `/app/secrets`
+3. Service account'u `/app/secrets/firebase-service-account.json` olarak upload et
+
+### 4. Deploy
+
+```bash
+git add .
+git commit -m "Railway + Firebase deployment setup"
+git push origin main
+```
+
+Railway otomatik deploy edecek!
+
+---
+
+## 🌐 Frontend Configuration
+
+### 1. API Base URL Güncelle
+
+`web/app.js` ve `web/create_report.js`:
+
+```javascript
+// Production
+const API_BASE_URL = 'https://your-app.railway.app/api';
+
+// Veya environment detection:
+const API_BASE_URL = window.location.hostname === 'localhost' 
+  ? 'http://localhost:5001/api'
+  : 'https://your-app.railway.app/api';
+```
+
+### 2. Firebase Hosting Deploy
+
+```bash
+firebase deploy --only hosting
+```
+
+---
+
+## 🎯 Cache System Nasıl Çalışır?
+
+### İlk Data Upload (Kullanıcı veriyi ilk kez yüklüyor):
+
+```
+1. User uploads data.csv
+2. Backend embedding yapıyor (10-15 saniye)
+   ├─ embeddings.npy oluşturuluyor
+   ├─ faiss_index.bin oluşturuluyor
+   └─ metadata.json oluşturuluyor
+3. Firebase Storage'a upload ediliyor 📤
+   └─ user_embeddings/{userId}/
+       ├─ embeddings.npy
+       ├─ faiss_index.bin
+       ├─ metadata.json
+       └─ data.csv
+4. Kullanıcı search yapabiliyor ✅
+```
+
+### Sonraki Login'ler (Cache hit):
+
+```
+1. User login yapıyor
+2. Backend Firebase Storage'ı kontrol ediyor
+3. Artifacts bulunuyor! 📥
+4. Firebase'den indiriliy or (2-3 saniye)
+5. Local'e kaydediliyor
+6. Embedding yapılmıyor! ⏩ Cached version kullanılıyor
+7. Kullanıcı HEMEN search yapabiliyor ✅
+```
+
+### Veri Değiştiğinde:
+
+```
+1. User rapor ekliyor/değiştiriyor
+2. Backend embedding yeniliyor (10-15 saniye)
+3. Yeni artifacts Firebase'e upload ediliyor 📤
+4. Cache güncelleniyor ✅
+```
+
+---
+
+## 📊 Monitoring
+
+### Railway Logs
+
+Railway Dashboard → **Logs** → Şunları göreceksin:
+
+```
+✅ Firebase Storage initialized
+🔍 Checking Firebase Storage for cached embeddings...
+✅ Found cached embeddings in Firebase Storage!
+📥 Downloading artifacts for user xyz...
+✅ Downloaded: embeddings.npy (1.2 MB)
+✅ Downloaded: faiss_index.bin (856 KB)
+⏩ Skipping embedding generation - using cached version
+```
+
+### Firebase Storage
+
+Firebase Console → **Storage** → Göreceksin:
+
+```
+user_embeddings/
+├─ P8VtJgvODiXSbjOtCMqUTecivHR2/
+│  ├─ embeddings.npy (1.2 MB)
+│  ├─ faiss_index.bin (856 KB)
+│  ├─ metadata.json (2 KB)
+│  └─ data.csv (45 KB)
+└─ another-user-id/
+   └─ ...
+```
+
+---
+
+## 🐛 Troubleshooting
+
+### "Firebase Storage not initialized"
+
+```bash
+# Railway Variables kontrol et:
+FIREBASE_SERVICE_ACCOUNT=/app/firebase-service-account.json
+FIREBASE_STORAGE_BUCKET=your-project.appspot.com
+```
+
+### "Permission denied" hatası
+
+Firebase Storage Rules'u kontrol et:
+```javascript
+allow read, write: if request.auth != null && request.auth.uid == userId;
+```
+
+### Embedding yapılmaya devam ediyor
+
+Logs'a bak:
+```
+🔍 Checking Firebase Storage for cached embeddings...
+📝 No cached embeddings found, will generate new ones
+```
+
+Firebase Storage'da artifacts var mı kontrol et.
+
+---
+
+## 💰 Cost Estimation
+
+### Railway:
+- **Starter Plan**: $5/month (500 hours)
+- **Hobby Plan**: Free (500 hours/month, enough for development)
+
+### Firebase Storage:
+- **Spark Plan (Free)**: 1 GB storage, 1 GB/day download
+- **Blaze Plan (Pay as you go)**: 
+  - Storage: $0.026/GB/month
+  - Download: $0.12/GB
+  
+**Örnek:** 100 kullanıcı, her biri ~2MB embedding:
+- Storage: 200 MB = ~$0.005/month
+- Download (her kullanıcı ayda 10 login): 100 * 2MB * 10 = 2GB = ~$0.24/month
+
+**TOPLAM: ~$5-10/month** 🎉
+
+---

+
+## 🔐 Güvenlik ve İzolasyon
+
+### Veri İzolasyonu
+```python
+# Kullanıcı A'nın verileri
+/data/user_embeddings/user_abc123/
+
+# Kullanıcı B'nin verileri
+/data/user_embeddings/user_xyz456/
+
+# ❌ Kullanıcı A, Kullanıcı B'nin verilerini GÖREMEZ!
+```
+
+### Firebase Authentication
+```javascript
+// Frontend'de user ID Firebase'den alınır
+const user = firebase.auth().currentUser;
+const userId = user.uid;  // Unique ve güvenli
+```
+
+### Backend Validation
+```python
+# Her request'te userId kontrol edilir
+user_id = custom_data_store.get('userId', 'anonymous')
+
+# Sadece o kullanıcının embeddings'i yüklenir
+user_dir = Path(f"data/user_embeddings/{user_id}")
+```
+
+---
+
+## ⚙️ Konfigürasyon
+
+### Embedding Modeli
+```python
+# src/user_embedding_pipeline.py
+
+model_name = 'paraphrase-multilingual-MiniLM-L12-v2'
+# - 384 dimensions
+# - Multilingual (Turkish support)
+# - Fast (50ms per text)
+```
+
+### FAISS Index
+```python
+# Cosine Similarity için normalize edilmiş Inner Product
+index = faiss.IndexFlatIP(embedding_dim)
+
+# Normalize edilmiş embeddings
+normalized = embeddings / np.linalg.norm(embeddings, axis=1, keepdims=True)
+index.add(normalized.astype('float32'))
+```
+
+### Cross-Encoder
+```python
+model_name = 'cross-encoder/mmarco-mMiniLMv2-L12-H384-v1'
+# - Multilingual
+# - High accuracy
+# - Slower (200ms per pair, but only for top-K)
+```
+

+**2. Project Setup**
+```
+❯ Use an existing project
+```
+→ Enter
+
+**3. Select a default Firebase project**
+```
+❯ jira-duplicate-detection (jira-duplicate-detection-xxxxx)
+```
+→ Enter
+
+**4. What do you want to use as your public directory?**

+## 5️⃣ Test Et
+
+Tarayıcıda aç:
+- **https://jira-duplicate-detection-xxxxx.web.app**
+
+---
+
+## ⚠️ Önemli Notlar
+
+1. **Backend Bağlantısı**:
+   - Şu anda frontend yayında ama backend lokal
+   - Backend'i de deploy etmek için Railway kullanacağız (sonraki adım)
+
+2. **API URL Güncellemesi**:
+   - Backend deploy olduktan sonra:
+   - `web/app.js` ve `web/create_report.js` içinde
+   - `API_BASE_URL` değiştir
+   - `firebase deploy` tekrar çalıştır
+
