# Phase 8: Architecture/Convention Review

> Overall codebase quality verification

## Purpose

Review the entire codebase before deployment. Identify architecture consistency, convention compliance, and potential issues.

## What to Do in This Phase

1. **Architecture Review**: Review structural consistency
2. **Convention Review**: Verify rule compliance
3. **Code Quality Review**: Duplication, complexity, potential bugs
4. **Refactoring**: Fix discovered issues

## Deliverables

```
docs/03-analysis/
├── architecture-review.md      # Architecture review
├── convention-review.md        # Convention review
└── refactoring-plan.md         # Refactoring plan
```

## PDCA Application

- **Plan**: Define review scope/criteria
- **Design**: Design checklist
- **Do**: Execute code review
- **Check**: Analyze issues
- **Act**: Refactor and proceed to Phase 9

## Level-wise Application

| Level | Application Method |
|-------|-------------------|
| Starter | Can be skipped (simple projects) |
| Dynamic | Required |
| Enterprise | Required + security review |

### Phase-specific Verification Checklist

#### Phase 1 → Verify: Terminology/Schema Consistency
```
□ Are glossary.md terms consistently used in code?
  - Business terms → Code naming matching
  - Global standard terms → API response field names matching
□ Do entity definitions match actual types?
□ Do relationship definitions match actual implementation?
```

#### Phase 2 → Verify: Convention Compliance
```
□ Naming rule compliance (PascalCase, camelCase, UPPER_SNAKE_CASE)
□ Folder structure rule compliance
□ Environment variable naming rule compliance (NEXT_PUBLIC_*, DB_*, API_*, etc.)
□ .env.example template completion
□ Environment variable validation logic (lib/env.ts) exists
```

#### Phase 4 → Verify: API Consistency
```
□ RESTful principle compliance
  - Resource-based URLs (nouns, plural)
  - Correct HTTP method usage
  - Status code consistency
□ Response format consistency
  - Success: { data, meta? }
  - Error: { error: { code, message, details? } }
  - Pagination: { data, pagination }
□ Error code standardization (matches ERROR_CODES constant)
```

#### Phase 5 → Verify: Design System Consistency
```
□ Are design tokens defined? (CSS Variables / ThemeData)
□ Do components use tokens? (no hardcoded colors)
□ Are component variants consistent?
□ Dark mode support (if defined)
```

#### Phase 6 → Verify: UI-API Integration Consistency
```
□ API client layer structure compliance
  - Components → hooks → services → apiClient
  - No direct fetch calls
□ Type consistency
  - Phase 4 API spec types = Phase 6 client types
□ Error handling consistency
  - Global error handler usage
  - Error code-specific handling logic
□ State management pattern consistency
```

#### Phase 7 → Verify: Security/SEO Application
```
□ Authentication/authorization middleware applied
□ Input validation (server-side)
□ XSS, CSRF defense
□ No sensitive info exposed to client
□ SEO meta tags applied
```

#### Phase 9 → Verify: Deployment Readiness
```
□ Environment variable Secrets registered (based on Phase 2 list)
□ Environment separation (dev/staging/prod)
□ Build successful
□ Environment variable validation script passes
```
