Deep Code Review

Review the following {{language}} code for a {{project_type}} project.

Analyze it across these dimensions:

1. **Correctness**: Identify any bugs, logic errors, or unhandled edge cases
2. **Architecture**: Does this follow {{architecture_pattern}} principles? Flag violations with specific fixes
3. **Performance**: Note any O(n^2) or worse operations, unnecessary allocations, or missed caching opportunities
4. **Security**: Check for injection vulnerabilities, improper input validation, or leaked secrets
5. **Readability**: Suggest naming improvements and identify overly complex functions (>30 lines)

For each issue found:
- Severity: Critical / Warning / Suggestion
- Line reference or code snippet
- Concrete fix (show the corrected code, not just a description)

End with a summary: "X critical, Y warnings, Z suggestions" and an overall quality score out of 10.
