Architecture Audit

Priority: P1 (STANDARD)

1. Discover Structural Duplication

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

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

See implementation examples for detection scripts.

2. Detect Logic Leakage (by Ecosystem)

Find business logic trapped in the wrong layer.

• Web (React/Next.js/Vue): grep -rE "useEffect|useState|useMemo" components --include="*.tsx" | wc -l — if components/ hook count > 20x hooks/ folder, architecture is monolithic.
• Mobile (Flutter/React Native): grep -rE "http\.|dio\.|socket\." lib/widgets --include="*.dart" | wc -l — I/O or state mutation > 5 lines in build() is High Debt.
• Backend (NestJS/Go/Spring): grep -rE "Repository\.|Query\.|db\." src/controllers --include="*.ts" | wc -l — Controllers must only handle request parsing and response formatting.

3. Identify Monoliths

Flag massive files violating Single Responsibility Principle.

• UI: > 500 lines (Medium), > 1,000 lines (Critical).
• Backend Services: > 1,500 lines indicates "God Class".

See implementation examples for monolith detection scripts.

4. Audit Resource Performance

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

• Resources > 1,000 lines require granulation.

See implementation examples for resource audit scripts.

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.

Anti-Patterns

• No applying generic patterns over project-specific rules: Respect existing architecture constraints.
• No ignoring error handling or edge cases: Audit must cover boundary conditions.
