 ⏺ Based on my review, this PR introduces three major components to the codebase:

  Architecture Overview

  Codex - A metadata storage system replacing previous reflection/project crates, managing PHP codebase information including types, symbols, and class/function metadata.

  Algebra - A boolean algebra engine for logical operations, implementing CNF clause manipulation with saturation algorithms for type assertion analysis.

  Analyzer - The core type checker performing static analysis, detecting ~290 different issue types with dataflow and effect analysis capabilities.

  Key Strengths

  1. Clean separation of concerns with well-defined module boundaries
  2. Comprehensive type system supporting unions, intersections, generics, and literals
  3. Parallel analysis using async/await for file processing
  4. Extensive issue detection with detailed categorization

  Critical Concerns

  1. Performance risks:
    - Recursive algorithms in algebra module could stack overflow
    - Excessive cloning operations throughout (particularly in crates/algebra/src/clause.rs and crates/analyzer/src/ttype.rs)
    - Missing benchmarks for performance validation
  2. Safety issues:
    - Multiple unwrap() calls that could panic in production
    - Complex hash calculations using wrapping arithmetic need careful review
  3. Documentation gaps:
    - Algebra crate lacks description in Cargo.toml
    - Complex algorithms (especially CNF saturation) need detailed documentation
    - Missing examples for public APIs

  Recommendations

  1. Immediate: Replace unwrap() with proper error handling
  2. Short-term: Add comprehensive tests for algebra operations and edge cases
  3. Medium-term: Implement Arc/Cow to reduce memory overhead from cloning
  4. Long-term: Consider breaking down large enums (290+ variants in issue.rs) for maintainability

  The PR represents solid engineering work with a well-thought-out architecture. However, it needs additional safety checks and performance optimization before production deployment.
