🎯 Key Features

✅ Validation & Analysis

  • Composition rule validation (10+ rules)
  • Dependency graph analysis (DFS, Kahn's algorithm)
  • Cycle detection (Tarjan's SCC)
  • Transitive dependency calculation (Floyd-Warshall)

✅ Pattern Detection

  • 5 Anti-Patterns: Upward Dependency, Horizontal Dependency, Circular Dependency, Leaky Abstraction, God Object
  • 7 Good Patterns: Layered Architecture, Facade, Dependency Inversion, Composition, SRP, ISP, Acyclic Dependencies

✅ Build & Deployment

  • Topological sort (O(V+E))
  • Parallel build optimization
  • Critical path calculation
  • Multiple export formats (shell, make, CMake, JSON)

✅ Enforcement & Quality

  • 3 policies: Strict, Balanced, Permissive
  • Configurable severity levels (IGNORE, WARN, ERROR, BLOCK)
  • Exemption workflow (PENDING → APPROVED/REJECTED)
  • Expiry tracking and auto-extension

✅ Metrics & Reporting

  • 3 metric categories: Dependency, Complexity, Quality
  • 30+ metrics collected
  • Trend analysis (linear regression)
  • Multiple export formats (JSON, CSV, HTML, badges)
