You are presenting to C-level executives about a critical technical assessment. Create a comprehensive executive summary.

REPOSITORY METRICS:
- Total Files: {analysis.total_files}
- Lines of Code: {analysis.total_lines:,}
- Languages: {', '.join(list(analysis.languages.keys())[:5]) if analysis.languages else 'Unknown'}
- Code Quality Score: {analysis.code_quality_score:.1f}/10

CRITICAL FINDINGS:
- Total Issues Identified: {total_issues}
- Critical Files (Score < 4): {critical_files}
- High Priority Files (Score 4-6): {high_priority_files}
- Large Monolithic Files (>500 lines): {large_files}
- Security Vulnerabilities: {security_issues}
- High Quality Files (Score 8+): {len([fa for fa in analysis.file_analyses if fa.severity_score >= 8])}

Create a comprehensive executive summary covering:

1. **BUSINESS IMPACT OVERVIEW** (2-3 paragraphs):
   - What this application/system does for the business
   - How current technical debt is affecting business operations
   - Specific business risks and their potential impact

2. **CRITICAL SYSTEM STATISTICS** (bullet points):
   - Total issues and their business impact
   - Largest problematic files affecting performance
   - Security vulnerabilities requiring immediate attention
   - Test coverage gaps affecting reliability

3. **KEY BUSINESS RISKS** (3-5 critical risks):
   - System reliability and downtime risks
   - Development velocity impact on revenue
   - Security vulnerabilities and compliance risks
   - Scalability limitations affecting growth
   - Technical debt costs and competitive disadvantage

4. **FINANCIAL IMPACT ASSESSMENT**:
   - Development velocity impact (percentage of time on fixes vs features)
   - Technical debt cost estimation
   - Infrastructure cost implications
   - System capacity limitations
   - Maintenance overhead costs

5. **IMMEDIATE ACTIONS REQUIRED** (Next 24-48 hours):
   - Critical files requiring immediate fixes
   - Security vulnerabilities needing urgent attention
   - Process improvements to prevent further degradation

Focus on business outcomes, financial impact, and competitive implications. Use non-technical language that executives can understand and act upon. Keep under 1000 words but be comprehensive.

You are creating a JUNIOR DEVELOPER IMPLEMENTATION GUIDE for a codebase. Generate a comprehensive, practical guide that helps junior developers understand the current codebase and write better code.

PROJECT CONTEXT:
- Languages Used: {', '.join(languages.keys()) if languages else 'Unknown'}
- Total Files: {analysis.total_files}
- Total Lines: {analysis.total_lines:,}
- Average Code Quality: {analysis.code_quality_score:.1f}/10
- Has C#/.NET: {has_csharp}
- Has React/TypeScript: {has_react}
- Has Python: {has_python}
- Has Java: {has_java}

CURRENT CODEBASE ISSUES:
{analysis.architecture_assessment[:500] if analysis.architecture_assessment else 'No architecture assessment available'}

PROBLEMATIC CODE EXAMPLES FROM ANALYSIS:
{code_samples_text}

GENERATE A COMPREHENSIVE GUIDE INCLUDING:

1. UNDERSTANDING CURRENT SYSTEM PROBLEMS
   1.1 How to Identify Monoliths
   - Use actual patterns found in this codebase
   - Show REAL examples from the problematic files above
   - Explain what SPECIFIC problems this codebase has
   
   1.2 How to Identify Database Issues
   - Focus on actual database patterns in this project
   - Use specific examples from the code
   
   1.3 How to Identify Frontend Issues (if React detected)
   - Show specific frontend patterns from this codebase

2. IMPLEMENTATION PATTERNS FOR NEW CODE
   Generate templates based on the actual technologies used:
   - For C# projects: Service, Repository, Controller patterns
   - For React projects: Component, Hook, State management patterns
   - Use the SAME coding style as the existing codebase
   - Include dependency injection setup specific to this project

3. TESTING PATTERNS FOR NEW CODE
   3.1 Unit Test Template - use actual testing frameworks in this codebase
   3.2 Integration Test Template - based on the actual project structure

4. CODE REVIEW CHECKLIST
   Create checklists based on ACTUAL issues found in this codebase:
   4.1 What to REJECT - use specific issues from the analysis
   4.2 What to REQUIRE - based on what's missing in current code
   4.3 Performance Review Checklist - address actual performance issues found
   4.4 Security Review Checklist - based on actual security concerns

6. COMMON PITFALLS AND HOW TO AVOID THEM
   Show ACTUAL pitfalls found in this codebase:
   6.1 Framework-specific pitfalls (Entity Framework, React, etc.)
   6.2 Async/Await Pitfalls
   6.3 Exception Handling Pitfalls
   6.4 Additional pitfalls specific to this codebase

7. DEBUGGING AND TROUBLESHOOTING GUIDE
   Based on the actual project setup:
   7.1 Performance Debugging - specific to this stack
   7.2 Database Query Debugging - tools and techniques for this project
   7.3 Memory Debugging - specific to this technology stack

8. DEPLOYMENT AND OPERATIONS GUIDE
   Based on actual deployment setup:
   8.1 Environment-Specific Configuration - actual config structure
   8.2 Health Checks Configuration - specific to this application

CRITICAL FORMATTING REQUIREMENTS:
- Format all sections with clear hierarchical headings using <b></b> tags
- Use proper bullet points - each bullet point should be on its own line with <br/> before it
- Format: <b>Heading:</b> followed by bullet points on separate lines
- Example CORRECT format:
  <b>Key Indicators:</b><br/>
  • First item<br/>
  • Second item<br/>
  • Third item<br/>
  
- Example WRONG format:
  <b>Key Indicators:</b> - First item - Second item - Third item (all on same line)
  
- Use <br/><br/> to separate paragraphs
- Each bullet point must be on its own line with proper line breaks
- Use actual examples from the codebase when possible
- Be specific to this project's technology stack
- Focus on REAL issues found in the analysis
- Provide practical, actionable guidance
- Format code examples with &#123; and &#125; for curly braces
- Keep it comprehensive but practical
