10.1 Tools & Methods Used

This audit was conducted using the following tools and methods:

Code Analysis Tools

  • Manual Code Review: Comprehensive manual review of source code, configuration files, and project structure
  • Semantic Code Search: Used codebase search tools to identify patterns, security issues, and architectural decisions
