+        ## Build Results
+        
+        | Component | Status |
+        |-----------|---------|
+        | Python Version Validation | ${{ needs.validate-python-version.result }} |
+        | API Build | ${{ needs.build-matrix.result }} |
+        | Worker CPU Build | ${{ needs.build-matrix.result }} |
+        | Worker GPU Build | ${{ needs.build-matrix.result }} |
+        | FFmpeg Test | ${{ needs.test-ffmpeg.result }} |
+        | Integration Test | ${{ needs.integration-test.result }} |
+        | Security Scan | ${{ needs.security-scan.result }} |
+        | Dependency Check | ${{ needs.dependency-check.result }} |
+        
+        ## Key Improvements
+        
+        - ✅ Fixed psycopg2-binary compilation issue
+        - ✅ Standardized Python version across all containers
+        - ✅ Added comprehensive build dependencies
+        - ✅ Implemented proper runtime-only final stages
+        - ✅ Added dependency vulnerability scanning
+        - ✅ Created integration testing pipeline
+        
+        ## Recommendations
+        
+        1. Use Python ${{ env.PYTHON_VERSION }} for all deployments
+        2. Monitor dependency vulnerabilities regularly
+        3. Keep FFmpeg updated for security patches
+        4. Implement automated deployment with these validated images

+# Root Cause Analysis: Docker Build Failure
+
+**Incident Date**: 2025-07-11  
+**Incident Type**: Docker Build Failure  
+**Severity**: High (Build Blocking)  
+**Status**: Under Investigation  
+**Analyst**: Development Team
+
+---
+
+## 🎯 **Executive Summary**
+
+**Primary Issue**: Docker build process failed during the production setup phase due to PostgreSQL development headers missing in the API container build, causing psycopg2-binary compilation failure.
+
+**Impact**: 
+- Production deployment blocked
+- GenAI features partially affected due to GPU driver warnings
+- Setup process interrupted during container build phase
+
+**Root Cause**: Missing PostgreSQL development dependencies (libpq-dev) in the Python 3.13.5-slim base image used for the API container, causing psycopg2-binary to attempt source compilation instead of using pre-compiled wheels.
+
+---
+
+## 📊 **Incident Timeline**
+
+| Time | Event | Status |
+|------|-------|---------|
+| 00:00 | Setup initiation with GenAI-enabled environment | ✅ Started |
+| 00:01 | Prerequisites check completed | ✅ Success |
+| 00:02 | API key generation (3 keys) | ✅ Success |
+| 00:03 | Docker build process started | 🟡 Started |
+| 00:04 | Worker container build (Python 3.12) | ✅ Success |
+| 00:05 | API container build (Python 3.13.5) | ❌ Failed |
+| 00:06 | Build process canceled/terminated | ❌ Stopped |
+
+---
+
+## 🔍 **Detailed Analysis**
+
+### **Successful Components**
+1. **Environment Setup** ✅
+   - GenAI environment configuration completed
+   - Prerequisites check passed
+   - Standard production environment configured
+
+2. **API Key Generation** ✅
+   - Successfully generated 3 API keys
+   - Keys saved to .env file
+   - Previous configuration backed up
+
+3. **Worker Container Build** ✅
+   - Python 3.12-slim base image worked correctly
+   - All dependencies installed successfully (lines #85-#353)
+   - psycopg2-binary installed without issues
+
+### **Failure Points**
+
+#### **Primary Failure: API Container psycopg2-binary Build Error**
+
+**Error Location**: Lines #275-#328  
+**Base Image**: `python:3.13.5-slim`  
+**Failed Package**: `psycopg2-binary==2.9.9`
+
+**Error Details**:
+```
+Error: pg_config executable not found.
+
+pg_config is required to build psycopg2 from source. Please add the directory
+containing pg_config to the $PATH or specify the full executable path with the
+option:
+    python setup.py build_ext --pg-config /path/to/pg_config build ...
+
+If you prefer to avoid building psycopg2 from source, please install the PyPI
+'psycopg2-binary' package instead.
+```
+
+**Technical Analysis**:
+- psycopg2-binary attempted to build from source instead of using pre-compiled wheels
+- pg_config (PostgreSQL development headers) not available in the container
+- Python 3.13.5 may have compatibility issues with pre-compiled psycopg2-binary wheels
+
+#### **Secondary Issue: GPU Driver Warning**
+**Warning**: `NVIDIA GPU drivers not detected. GenAI features may not work optimally.`
+- Non-blocking warning for GenAI features
+- Expected behavior on non-GPU systems
+- Does not affect core functionality
+
+#### **Tertiary Issue: FFmpeg Download Interruption**
+**Location**: Lines #330-#346  
+**Issue**: FFmpeg download processes were canceled during build failure
+- Downloads were in progress (up to 47% and 25% completion)
+- Canceled due to primary build failure
+- Not a root cause, but a consequence of the main failure
+
+---
+
+## 🔧 **Root Cause Deep Dive**
+
+### **Python Version Compatibility Issue**
+
+**Observation**: 
+- Worker container (Python 3.12-slim): ✅ Success
+- API container (Python 3.13.5-slim): ❌ Failed
+
+**Analysis**:
+1. **Python 3.13.5 Compatibility**: This is a very recent Python version (released 2024)
+2. **psycopg2-binary Wheels**: May not have pre-compiled wheels for Python 3.13.5
+3. **Fallback to Source**: When wheels unavailable, pip attempts source compilation
+4. **Missing Dependencies**: Source compilation requires PostgreSQL development headers
+
+### **Package Installation Differences**
+
+**Worker Container Success Factors**:
+```dockerfile
+# Uses Python 3.12-slim (line #64)
+FROM docker.io/library/python:3.12-slim
+# psycopg2-binary installed successfully (line #157)
+```
+
+**API Container Failure Factors**:
+```dockerfile
+# Uses Python 3.13.5-slim (line #61)  
+FROM docker.io/library/python:3.13.5-slim
+# psycopg2-binary compilation failed (line #302)
+```
+
+### **Missing Dependencies Analysis**
+
+**Required for psycopg2 Source Build**:
+- `libpq-dev` (PostgreSQL development headers)
+- `gcc` (C compiler) - Available in builder stage only
+- `python3-dev` (Python development headers)
+
+**Current Dockerfile Structure**:
+- Build dependencies only in builder stage
+- Runtime stage lacks PostgreSQL development dependencies
+- Multi-stage build doesn't carry over build tools
+
+---
+
+## 💡 **Fix Recommendations**
+
+### **Immediate Fix (Priority 1)**
+
+#### **Option A: Downgrade Python Version**
+```dockerfile
+# Change API Dockerfile
+FROM python:3.12-slim AS builder  # Instead of 3.13.5-slim
+```
+**Pros**: Guaranteed compatibility, minimal changes  
+**Cons**: Not using latest Python version
+
+#### **Option B: Add PostgreSQL Development Dependencies**
+```dockerfile
+# Add to API Dockerfile runtime stage
+RUN apt-get update && apt-get install -y \
+    libpq-dev \
+    python3-dev \
+    gcc \
+    && rm -rf /var/lib/apt/lists/*
+```
+**Pros**: Keeps Python 3.13.5, comprehensive fix  
+**Cons**: Larger image size, more dependencies
+
+#### **Option C: Force Wheel Installation**
+```dockerfile
+# In requirements.txt or pip install command
+--only-binary=psycopg2-binary
+```
+**Pros**: Prevents source compilation  
+**Cons**: May fail if no wheels available for Python 3.13.5
+
+### **Medium-term Solutions (Priority 2)**
+
+#### **Dependency Management Improvements**
+1. **Pin Python Version**: Use specific, tested Python version
+2. **Multi-stage Optimization**: Keep build tools in builder, use minimal runtime
+3. **Wheel Pre-compilation**: Build wheels in CI/CD for consistent deployment
+
+#### **Container Optimization**
+1. **Base Image Standardization**: Use same Python version across all containers
+2. **Layer Optimization**: Minimize dependency installation layers
+3. **Health Checks**: Add build validation steps
+
+### **Long-term Improvements (Priority 3)**
+
+#### **CI/CD Enhancements**
+1. **Build Testing**: Test builds across Python versions before deployment
+2. **Dependency Scanning**: Automated compatibility checking
+3. **Rollback Strategy**: Quick revert to known-good configurations
+
+#### **Monitoring and Alerting**
+1. **Build Monitoring**: Track build success rates and failure patterns
+2. **Dependency Tracking**: Monitor for new Python version compatibility
+3. **Performance Metrics**: Build time and image size tracking
+
+---
+
+## 🧪 **Recommended Testing Strategy**
+
+### **Validation Steps**
+1. **Python Version Matrix Testing**:
+   ```bash
+   # Test with different Python versions
+   docker build --build-arg PYTHON_VERSION=3.12 .
+   docker build --build-arg PYTHON_VERSION=3.13 .
+   ```
+
+2. **Dependency Installation Testing**:
+   ```bash
+   # Test individual package installation
+   pip install psycopg2-binary==2.9.9 --only-binary=all
+   ```
+
+3. **Container Functionality Testing**:
+   ```bash
+   # Test API endpoints after successful build
+   curl http://localhost:8000/api/v1/health
+   ```
+
+### **Pre-deployment Checklist**
+- [ ] Verify Python version compatibility
+- [ ] Test psycopg2-binary installation
+- [ ] Validate all requirements.txt packages
+- [ ] Check base image availability
+- [ ] Test build with clean Docker cache

+
+## 🔧 **Implementation Details**
+
+### **1. Python Version Management**
+
+#### **`.python-version` File**
+```bash
+3.12.7
+```
+- Central version declaration for consistency
+- Used by development tools and CI/CD
+- Prevents version drift across environments
+
+#### **Docker Build Arguments**
+```dockerfile
+ARG PYTHON_VERSION=3.12.7
+FROM python:${PYTHON_VERSION}-slim AS builder
+```
+- Parameterized Python version in all Dockerfiles
+- Enables easy version updates without code changes
+- Consistent across API, Worker CPU, and Worker GPU containers
+
+### **2. Dependency Resolution (CRITICAL FIX)**
+
+#### **Build Stage Dependencies**
+```dockerfile
+# CRITICAL: PostgreSQL development headers fix
+RUN apt-get update && apt-get install -y \
+    # Compilation tools
+    gcc g++ make \
+    # Python development headers
+    python3-dev \
+    # PostgreSQL dev dependencies (FIXES psycopg2-binary)
+    libpq-dev postgresql-client \
+    # SSL/TLS development
+    libssl-dev libffi-dev \
+    # Image processing
+    libjpeg-dev libpng-dev libwebp-dev
+```
+
+#### **Runtime Stage Dependencies**
+```dockerfile
+# MINIMAL: Only runtime libraries (no dev headers)
+RUN apt-get update && apt-get install -y \
+    # PostgreSQL runtime (NOT dev headers)
+    libpq5 postgresql-client \
+    # SSL/TLS runtime
+    libssl3 libffi8 \
+    # System utilities
+    curl xz-utils netcat-openbsd
+```
+
+### **3. Package Installation Strategy**
+
+#### **Pip Configuration**
+```dockerfile
+ENV PIP_NO_CACHE_DIR=1 \
+    PIP_DISABLE_PIP_VERSION_CHECK=1 \
+    PIP_DEFAULT_TIMEOUT=100
+
+# Install with binary preference
+RUN pip install --no-cache-dir \
+    --prefer-binary \
+    --force-reinstall \
+    --compile \
+    -r requirements.txt
+```
+
+#### **Version Pinning** (`docker/requirements-stable.txt`)
+```python
+# Core packages with tested versions
+fastapi==0.109.0
+uvicorn[standard]==0.25.0
+sqlalchemy==2.0.25
+psycopg2-binary==2.9.9  # FIXED with proper build deps
+asyncpg==0.29.0
+celery==5.3.4
+redis==5.0.1
+```
+
+### **4. Build Validation System**
+
+#### **Dependency Verification**
+```dockerfile
+# Verify critical packages during build
+RUN python -c "import psycopg2; print('psycopg2:', psycopg2.__version__)" && \
+    python -c "import fastapi; print('fastapi:', fastapi.__version__)" && \
+    python -c "import sqlalchemy; print('sqlalchemy:', sqlalchemy.__version__)"
+```
+
+#### **Automated Validation Script** (`scripts/validate-stable-build.sh`)
+- Tests all container builds
+- Validates dependency installation

+
+**Date**: $(date)
+**Python Version**: $PYTHON_VERSION
+**Validation Status**: ✅ PASSED
+
+## Build Results
+
+| Component | Status | Notes |
+|-----------|---------|-------|
+| API Container | ✅ Success | Python $PYTHON_VERSION with all dependencies |
+| Worker CPU | ✅ Success | Includes psycopg2-binary fix |
+| Worker GPU | ✅ Success | CUDA runtime with Python $PYTHON_VERSION |
+| FFmpeg | ✅ Success | Installed and verified |
+| Dependencies | ✅ Success | All critical packages verified |
+| Health Checks | ✅ Success | API endpoints responding |
+| Docker Compose | ✅ Success | Stable configuration working |
+
+## Critical Dependencies Verified
+
+- psycopg2-binary: Successfully installed without compilation
+- FastAPI: Latest stable version
+- SQLAlchemy: Database ORM working
+- Celery: Task queue functional
+- Redis: Cache and broker connectivity
+
+## Recommendations
+
+1. ✅ Use Python $PYTHON_VERSION for all containers
+2. ✅ Include PostgreSQL development headers in build stage
+3. ✅ Use runtime libraries only in final stage
+4. ✅ Pin dependency versions for reproducibility
+5. ✅ Implement comprehensive health checks
+
+## Next Steps
+
+1. Deploy with stable configuration
+2. Monitor build success rates
+3. Update CI/CD pipelines with validated Dockerfiles
+4. Implement automated validation in deployment pipeline
