Comprehensive Production Implementation Audit
============================================

This script conducts a thorough audit of the codebase to identify and categorize
all non-production code implementations including:
- Mock/fake/stub implementations
- TODO/FIXME comments 
- Hard-coded test values
- Development-only code paths
- Incomplete production implementations

Usage:
    python3 comprehensive_production_audit.py [--fix] [--report-only]
    
Options:
    --fix          Attempt to implement production replacements
    --report-only  Only generate the audit report without fixes
