Architecture Audit

Priority: P1 (STANDARD)

📋 Audit Protocol

1. Structural Duplication Discovery (Universal)

Identify split sources of truth by searching for redundant directory patterns or naming conventions.

• Services: Compare Service.ts vs ServiceNew.ts vs ServiceV2.ts.
• Versioning: Check for /v1, /v2 or "Refactor" folders.
• Action:

  # Identify potential duplicates or legacy files
  find . -type f -name "*New.*" | sed 's/New//'
  

2. Logic Leakage Analysis (Ecosystem Specific)

Detect business logic trapped in the wrong layer (e.g., UI layer in apps, Controller layer in APIs).

🌐 Web (React/Next.js/Vue)

• Action: grep -rE "useEffect|useState|useMemo" components --include="*.tsx" | wc -l
• Threshold: If components/ hook count > 20x hooks/ folder, architecture is Monolithic.

📱 Mobile (Flutter/React Native)

• Action: grep -rE "http\.|dio\.|socket\." lib/widgets --include="*.dart" | wc -l
• Threshold: I/O or state mutation > 5 lines in build() is 🟠 High Debt.

⚙️ Backend (NestJS/Go/Spring)

• Action: grep -rE "Repository\.|Query\.|db\." src/controllers --include="*.ts" | wc -l
• Threshold: Controllers must only handle request parsing and response formatting.

3. Monolith Detection (Ecosystem Specific)

Identify massive files violating Single Responsibility Principle.

• Thresholds:
  • UI: > 500 lines (🟡 Medium), > 1,000 lines (🔴 Critical).
  • Backend Services: > 1,500 lines indicate "God Class".
• Action:

  find . -type f \( -name "*.tsx" -o -name "*.dart" -o -name "*.go" -o -name "*.java" \) | xargs wc -l | awk '$1 > 1000'
  

4. Resource Performance Audit (Universal)

Check for large metadata or constants impacting IDE performance and binary size.

• Threshold: Resources > 1,000 lines require granulation.
• Action:

  find . -type f \( -name "*constants*" -o -name "*.graphql" -o -name "*strings*" \) | xargs wc -l | awk '$1 > 1000'
  

⚖️ Scoring Impact

• Layer Violation: -15 per business logic instance in UI/Controller layer.
• Structural Fragmentation: -10 per duplicated legacy entity.
• Monoliths: -10 per unit > 1,000 lines.
