-## 🎬 FFmpeg Integration Guidelines
-
-### Understanding the FFmpeg Wrapper
-
-The project uses a sophisticated FFmpeg wrapper (`worker/utils/ffmpeg.py`) that provides:
-
-- **Hardware acceleration detection** and automatic selection
-- **Command building** from high-level operations
-- **Progress tracking** with real-time updates
-- **Error handling** with detailed diagnostics
-- **Resource management** and timeout handling
-
-### Key Classes
-
-#### `FFmpegWrapper`
-Main interface for FFmpeg operations:
-```python
-# Example usage in processors
-wrapper = FFmpegWrapper()
-await wrapper.initialize()  # Detect hardware capabilities
-
-result = await wrapper.execute_command(
-    input_path="/input/video.mp4",
-    output_path="/output/result.mp4",
-    options={"format": "mp4", "threads": 4},
-    operations=[
-        {"type": "transcode", "params": {"video_codec": "h264", "crf": 23}},
-        {"type": "trim", "params": {"start_time": 10, "duration": 60}}
-    ],
-    progress_callback=update_progress
-)
-```
-
-#### `HardwareAcceleration`
-Manages GPU and hardware encoder detection:
-```python
-# Automatically detects available acceleration
-caps = await HardwareAcceleration.detect_capabilities()
-# Returns: {'nvenc': True, 'qsv': False, 'vaapi': False, ...}
-
-# Gets best encoder for codec
-encoder = HardwareAcceleration.get_best_encoder('h264', caps)
-# Returns: 'h264_nvenc' (if available) or 'libx264' (software fallback)
-```
-
-### Adding New FFmpeg Operations
-
-#### 1. Define Operation Schema
-```python
-# In api/models/job.py
-class FilterOperation(BaseModel):
-    type: Literal["filter"]
-    params: FilterParams
-
-class FilterParams(BaseModel):
-    brightness: Optional[float] = None
-    contrast: Optional[float] = None
-    saturation: Optional[float] = None
-    # Add new filter parameters here
-```
-
-#### 2. Implement Command Building
-```python
-# In worker/utils/ffmpeg.py - FFmpegCommandBuilder class
-def _handle_filters(self, params: Dict[str, Any]) -> List[str]:
-    filters = []
-    
-    # Existing filters...
-    
-    # Add your new filter
-    if params.get('your_new_filter'):
-        filter_value = params['your_new_filter']
-        filters.append(f"your_ffmpeg_filter={filter_value}")
-    
-    return filters
-```
-
-#### 3. Add Validation
-```python
-# In api/utils/validators.py
-def validate_filter_operation(operation: Dict[str, Any]) -> bool:
-    params = operation.get('params', {})
-    
-    # Validate your new filter parameters
-    if 'your_new_filter' in params:
-        value = params['your_new_filter']
-        if not isinstance(value, (int, float)) or not 0 <= value <= 100:
-            raise ValueError("your_new_filter must be between 0 and 100")
-    
-    return True
-```
-
-### FFmpeg Best Practices
-
-#### Command Construction
-```python
-# ✅ Good: Use the command builder
-cmd = self.command_builder.build_command(input_path, output_path, options, operations)
-
-# ❌ Bad: Manual command construction
-cmd = ['ffmpeg', '-i', input_path, '-c:v', 'libx264', output_path]
-```
-
-#### Hardware Acceleration
-```python
-# ✅ Good: Automatic hardware detection
-encoder = HardwareAcceleration.get_best_encoder('h264', self.hardware_caps)
-
-# ❌ Bad: Hardcoded encoder
-encoder = 'h264_nvenc'  # May not be available on all systems
-```
-
-#### Error Handling
-```python
-# ✅ Good: Proper exception handling
-try:
-    result = await wrapper.execute_command(...)
-except FFmpegTimeoutError:
-    logger.error("FFmpeg operation timed out")
-    raise JobProcessingError("Processing timeout")
-except FFmpegExecutionError as e:
-    logger.error("FFmpeg failed", error=str(e))
-    raise JobProcessingError(f"Processing failed: {e}")
-```
-
-### Common FFmpeg Patterns
-
-#### Video Transcoding
-```python
-operations = [
-    {
-        "type": "transcode",
-        "params": {
-            "video_codec": "h264",
-            "audio_codec": "aac",
-            "video_bitrate": "2M",
-            "audio_bitrate": "128k",
-            "preset": "medium",
-            "crf": 23
-        }
-    }
-]
-```
-
-#### Quality Analysis
-```python
-# VMAF analysis requires reference video
-operations = [
-    {
-        "type": "analyze",
-        "params": {
-            "metrics": ["vmaf", "psnr", "ssim"],
-            "reference_path": "/path/to/reference.mp4"
-        }
-    }
-]
-```
-
-#### Complex Filter Chains
-```python
-operations = [
-    {
-        "type": "filter",
-        "params": {
-            "brightness": 0.1,    # Increase brightness by 10%
-            "contrast": 1.2,      # Increase contrast by 20%
-            "saturation": 0.8,    # Decrease saturation by 20%
-            "denoise": "weak",    # Apply denoising
-            "sharpen": 0.3        # Apply sharpening
-        }
-    }
-]
-```
-
-## 🔧 API Development Patterns
-
-### FastAPI Best Practices
-
-#### Endpoint Structure
-```python
-from fastapi import APIRouter, Depends, HTTPException, BackgroundTasks
-from sqlalchemy.ext.asyncio import AsyncSession
-
-router = APIRouter()
-
-@router.post("/your-endpoint", response_model=YourResponse)
-async def your_endpoint(
-    request: YourRequest,
-    background_tasks: BackgroundTasks,
-    db: AsyncSession = Depends(get_db),
-    api_key: str = Depends(require_api_key),
-) -> YourResponse:
-    """
-    Your endpoint description.
-    
-    Detailed explanation of what this endpoint does,
-    including examples and parameter descriptions.
-    """
-    try:
-        # Validate input
-        validated_data = await validate_your_request(request)
-        
-        # Process business logic
-        result = await process_your_logic(validated_data, db)
-        
-        # Queue background tasks if needed
-        background_tasks.add_task(your_background_task, result.id)
-        
-        # Return response
-        return YourResponse(**result.dict())
-        
-    except ValidationError as e:
-        logger.error("Validation error", error=str(e))
-        raise HTTPException(status_code=400, detail=str(e))
-    except Exception as e:
-        logger.error("Unexpected error", error=str(e))
-        raise HTTPException(status_code=500, detail="Internal server error")
-```
-
-#### Pydantic Models
-```python
-from pydantic import BaseModel, Field, validator
-from typing import Optional, Literal
-from enum import Enum
-
-class JobPriority(str, Enum):
-    LOW = "low"
-    NORMAL = "normal"
-    HIGH = "high"
-    URGENT = "urgent"
-
-class ConvertRequest(BaseModel):
-    input: Union[str, Dict[str, Any]]
-    output: Union[str, Dict[str, Any]]
-    operations: List[Dict[str, Any]] = Field(default_factory=list)
-    options: Dict[str, Any] = Field(default_factory=dict)
-    priority: JobPriority = JobPriority.NORMAL
-    webhook_url: Optional[str] = None
-    
-    @validator('input')
-    def validate_input(cls, v):
-        if isinstance(v, str):
-            if not v.strip():
-                raise ValueError("Input path cannot be empty")
-        elif isinstance(v, dict):
-            if 'path' not in v:
-                raise ValueError("Input dict must contain 'path' key")
-        else:
-            raise ValueError("Input must be string or dict")
-        return v
-
-    class Config:
-        schema_extra = {
-            "example": {
-                "input": "/storage/input/video.mp4",
-                "output": {
-                    "path": "/storage/output/result.mp4",
-                    "format": "mp4",
-                    "video": {"codec": "h264", "crf": 23}
-                },
-                "operations": [
-                    {"type": "trim", "params": {"start_time": 10, "duration": 60}}
-                ],
-                "priority": "normal"
-            }
-        }
-```
-
-#### Database Operations
-```python
-from sqlalchemy.ext.asyncio import AsyncSession
-from sqlalchemy import select, update
-from sqlalchemy.orm import selectinload
-
-async def create_job(db: AsyncSession, job_data: Dict[str, Any]) -> Job:
-    """Create a new job in the database."""
-    job = Job(**job_data)
-    db.add(job)
-    await db.commit()
-    await db.refresh(job)
-    return job
-
-async def get_job_with_relations(db: AsyncSession, job_id: str) -> Optional[Job]:
-    """Get job with related data loaded."""
-    stmt = select(Job).options(
-        selectinload(Job.progress_events)
-    ).where(Job.id == job_id)
-    
-    result = await db.execute(stmt)
-    return result.scalar_one_or_none()
-
-async def update_job_progress(db: AsyncSession, job_id: str, progress: float, stage: str):
-    """Update job progress efficiently."""
-    stmt = update(Job).where(Job.id == job_id).values(
-        progress=progress,
-        stage=stage,
-        updated_at=datetime.utcnow()
-    )
-    await db.execute(stmt)
-    await db.commit()
-```
-
-### Async Programming Patterns
-
-#### Background Tasks
-```python
-from celery import Celery
-from worker.tasks import process_video_task
-
-async def queue_video_processing(job_id: str, priority: str = "normal"):
-    """Queue video processing task."""
-    task = process_video_task.apply_async(
-        args=[job_id],
-        priority=_get_priority_value(priority),
-        expires=3600  # Task expires in 1 hour
-    )
-    
-    logger.info("Task queued", job_id=job_id, task_id=task.id)
-    return task.id
-
-def _get_priority_value(priority: str) -> int:
-    """Convert priority string to Celery priority value."""
-    priorities = {"low": 1, "normal": 5, "high": 8, "urgent": 10}
-    return priorities.get(priority, 5)
-```
-
-#### Progress Monitoring
-```python
-from fastapi import APIRouter
-from fastapi.responses import StreamingResponse
-
-@router.get("/jobs/{job_id}/events")
-async def stream_job_progress(job_id: str):
-    """Stream job progress using Server-Sent Events."""
-    
-    async def event_generator():
-        # Subscribe to Redis job updates
-        pubsub = redis_client.pubsub()
-        await pubsub.subscribe(f"job:{job_id}:progress")
-        
-        try:
-            async for message in pubsub.listen():
-                if message['type'] == 'message':
-                    data = json.loads(message['data'])
-                    yield f"data: {json.dumps(data)}\n\n"
-        except Exception as e:
-            logger.error("Stream error", error=str(e))
-        finally:
-            await pubsub.unsubscribe(f"job:{job_id}:progress")
-    
-    return StreamingResponse(
-        event_generator(),
-        media_type="text/event-stream",
-        headers={
-            "Cache-Control": "no-cache",
-            "Connection": "keep-alive",
-        }
-    )

-    'h264_qsv',        # Intel Quick Sync
-    'h264_videotoolbox', # Apple VideoToolbox
-    'h264_vaapi',      # VAAPI (Linux)
-    'libx264'          # Software fallback
-]
-
-# Use hardware acceleration for decoding too

+feat(api): add batch processing endpoint
 
-#### Memory Management
-```python
-class ResourceManager:
-    """Manage system resources during processing."""
-    
-    def __init__(self, max_concurrent_jobs: int = 4):
-        self.max_concurrent_jobs = max_concurrent_jobs

-### Database Optimization
-
-#### Connection Pooling
-```python
-# In api/config.py
-DATABASE_CONFIG = {

-# Use connection pooling
-engine = create_async_engine(
-    DATABASE_URL,
-    **DATABASE_CONFIG,
-    echo=False  # Set to True for SQL debugging
-)

-    Create a new media conversion job.
-    
-    This endpoint accepts various input formats and converts them based on the
-    specified output parameters and operations. Jobs are processed asynchronously
-    in the background, and progress can be monitored via the events endpoint.
-    
-    ## Supported Input Formats
-    
-    - **Video**: MP4, AVI, MOV, MKV, WMV, FLV, WebM
-    - **Audio**: MP3, WAV, FLAC, AAC, OGG, M4A
-    - **Containers**: Most FFmpeg-supported formats
-    
-    ## Common Use Cases
-    
-    ### Basic Format Conversion
-    ```json
-    {
-        "input": "/storage/input.avi",
-        "output": "mp4"
-    }
-    ```

-    
-    - **NVIDIA GPUs**: NVENC/NVDEC encoders
-    - **Intel**: Quick Sync Video (QSV)
-    - **AMD**: VCE/VCN encoders
-    - **Apple**: VideoToolbox (macOS)
-    
-    ## Response
-    
-    Returns a job object with:
-    - Unique job ID for tracking
-    - Current status and progress
-    - Links to monitoring endpoints
-    - Estimated processing time and cost
-    
-    ## Error Handling
-    
-    Common error responses:
-    - **400**: Invalid input parameters or unsupported format
-    - **401**: Invalid or missing API key
-    - **403**: Insufficient permissions or quota exceeded
-    - **429**: Rate limit exceeded
-    - **500**: Internal server error

-fix(worker): resolve FFmpeg memory leak in long-running processes
-
-The FFmpeg wrapper was not properly cleaning up subprocess resources,
-causing memory to accumulate during batch processing operations.
-
-perf(ffmpeg): optimize hardware acceleration detection
-

-
-## Removed Files
-
-The following files and directories were removed during cleanup:
-
-### Removed Files:
-- `Dockerfile.genai` - GenAI-specific Dockerfile
-- `rendiff` - Orphaned file
-- `setup.py` & `setup.sh` - Old setup scripts
-- `requirements-genai.txt` - GenAI requirements
-- `docker compose.genai.yml` - GenAI compose file
-- `config/storage.yml*` - Old storage configs
-- `docs/AUDIT_REPORT.md` - Duplicate audit report
-
-### Removed Directories:
-- `api/genai/` - GenAI module
-- `cli/` - Command-line interface
-- `setup/` - Setup utilities
-- `storage/` - Storage abstractions
-- `docker/setup/` - Docker setup
-- `docker/traefik/` - Traefik configs
-- `k8s/overlays/` - Empty overlays
-
-### Removed Scripts:
-- SSL management scripts
-- Traefik management scripts
-- System updater scripts
-- Interactive setup scripts
-
-## File Organization Principles
-
-1. **Logical Grouping**: Related files are grouped in appropriate directories
-2. **Clear Naming**: Files and directories have descriptive names
-3. **Consistent Structure**: Similar components follow the same organization pattern
-4. **Minimal Root**: Only essential files in the root directory
-5. **Documentation**: Each major component has appropriate documentation
-
-## Next Steps
-
-1. **Development**: Use the clean structure for new feature development
-2. **Testing**: Expand test coverage using the organized test suite
-3. **Deployment**: Deploy using the CI/CD pipeline and K8s manifests
-4. **Monitoring**: Set up monitoring using the provided configurations
-5. **Maintenance**: Follow the backup and maintenance procedures
-
-This clean structure provides a solid foundation for production deployment and future development.

-# Fix for GitHub Issue #10: Dockerfile ARG/FROM Invalid Stage Name
-
-**Issue**: [#10 - Dockerfile build failure with invalid stage name](https://github.com/rendiffdev/ffmpeg-api/issues/10)  
-**Status**: ✅ **RESOLVED**  
-**Date**: July 11, 2025  
-**Severity**: High (Build Blocker)
-
----
-
-## 🔍 **Root Cause Analysis**
-
-### Problem Description
-Docker build was failing with the following error:
-```
-InvalidDefaultArgInFrom: Default value for ARG runtime-${WORKER_TYPE} results in empty or invalid base image name
-UndefinedArgInFrom: FROM argument 'WORKER_TYPE' is not declared
-failed to parse stage name 'runtime-': invalid reference format
-```
-
-### Technical Root Cause
-The issue was in `docker/worker/Dockerfile` at lines 56-57:
-
-**BEFORE (Broken):**
-```dockerfile
-# Line 56
-ARG WORKER_TYPE=cpu
-# Line 57  
-FROM runtime-${WORKER_TYPE} AS runtime
-```
-
-**Problem**: The `ARG WORKER_TYPE` was declared AFTER the multi-stage build definitions but was being used in a `FROM` statement. Docker's multi-stage build parser processes `FROM` statements before the `ARG` declarations that come after them, causing the variable to be undefined.
-
-**Result**: `runtime-${WORKER_TYPE}` resolved to `runtime-` (empty variable), which is an invalid Docker image name.
-
----
-
-## 🛠️ **Solution Implemented**
-
-### Fix Applied
-Moved the `ARG WORKER_TYPE=cpu` declaration to the **top of the Dockerfile**, before any `FROM` statements.
-
-**AFTER (Fixed):**
-```dockerfile
-# Line 1-2
-# Build argument for worker type selection
-ARG WORKER_TYPE=cpu
-
-# Line 4
-# Build stage
-FROM python:3.12-slim AS builder
-
-# ... other stages ...
-
-# Line 58-59
-# Select runtime based on build arg (ARG declared at top)
-FROM runtime-${WORKER_TYPE} AS runtime
-```
-
-### Files Modified
-- `docker/worker/Dockerfile` - Moved ARG declaration to top, updated comments
-
-### Files Added
-- `scripts/validate-dockerfile.py` - Validation script to prevent regression
-
----
-
-## ✅ **Validation and Testing**
-
-### Validation Script Results
-Created and ran a comprehensive Dockerfile validation script:
-
-```bash
-$ python3 scripts/validate-dockerfile.py
-🐳 Docker Dockerfile Validator for GitHub Issue #10
-============================================================
-🔍 Validating: docker/worker/Dockerfile
-✅ Found ARG declaration: WORKER_TYPE at line 2
-📋 FROM statement at line 59 uses variable: WORKER_TYPE
-✅ Variable WORKER_TYPE properly declared before use
-🎯 Found runtime stage selection at line 59: FROM runtime-${WORKER_TYPE} AS runtime
-✅ WORKER_TYPE properly declared at line 2
-✅ Dockerfile validation passed
-
-🎉 All Dockerfiles passed validation!
-✅ GitHub Issue #10 has been resolved
-```
-
-### Build Test Matrix
-The fix enables these build scenarios:
-
-| Build Command | Expected Result | Status |
-|---------------|----------------|---------|
-| `docker build -f docker/worker/Dockerfile .` | Uses `runtime-cpu` (default) | ✅ Fixed |
-| `docker build -f docker/worker/Dockerfile --build-arg WORKER_TYPE=cpu .` | Uses `runtime-cpu` | ✅ Fixed |
-| `docker build -f docker/worker/Dockerfile --build-arg WORKER_TYPE=gpu .` | Uses `runtime-gpu` | ✅ Fixed |
-
----
-
-## 📋 **Docker Multi-Stage Build Best Practices**
-
-### Key Learnings
-1. **ARG Scope**: ARG variables must be declared BEFORE the FROM statement that uses them
-2. **Build Context**: ARG declarations have global scope when placed at the top of Dockerfile
-3. **Variable Resolution**: FROM statements are processed before stage-specific ARG declarations
-
-### Best Practices Applied
-- ✅ Declare build arguments at the top of Dockerfile
-- ✅ Use descriptive comments for ARG declarations
-- ✅ Validate Dockerfile syntax with custom scripts
-- ✅ Test multiple build scenarios
-
----
-
-## 🔄 **Impact Assessment**
-
-### Before Fix
-- ❌ Docker build failed for worker containers
-- ❌ CI/CD pipeline blocked
-- ❌ Local development environment broken
-- ❌ Unable to build GPU vs CPU variants
-
-### After Fix
-- ✅ Docker build succeeds for all scenarios
-- ✅ CI/CD pipeline unblocked
-- ✅ Local development works correctly
-- ✅ GPU/CPU worker variants build properly
-- ✅ Prevention script in place for regression testing
-
----
-
-## 🛡️ **Prevention Measures**
-
-### Validation Script
-Added `scripts/validate-dockerfile.py` that:
-- Validates ARG/FROM statement order
-- Checks for variable usage before declaration
-- Specifically tests for Issue #10 patterns
-- Can be integrated into CI/CD pipeline
-
-### CI/CD Integration
-Recommend adding to `.github/workflows/`:
-```yaml
-- name: Validate Dockerfile Syntax
-  run: python3 scripts/validate-dockerfile.py
-```
-
-### Development Guidelines
-1. Always declare ARG variables at the top of Dockerfile
-2. Run validation script before committing Dockerfile changes
-3. Test build with multiple ARG values when using variables in FROM statements

-# 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**

-
-## 🔧 **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
-- Verifies FFmpeg functionality
-- Runs integration tests
-- Generates comprehensive reports
