3a671a5707 refactor: add pattern utils and split api.ts into modules
1. Pattern Detection Utility (src/utils/patterns.ts)
- Centralize tool category patterns (domain, deposit, server, etc.)
- Add memory category patterns (company, tech, role)
- Add region detection (korea, japan, singapore, us)
- Add tech stack detection (postgres, redis, nodejs, etc.)
- Export detectToolCategories(), detectRegion(), detectTechStack()

2. API Route Modularization (src/routes/api/)
- deposit.ts: /balance, /deduct with apiKeyAuth middleware
- chat.ts: /test, /chat with session handling
- contact.ts: Contact form with CORS middleware
- metrics.ts: Circuit Breaker status endpoint

3. Updates
- tools/index.ts: Use detectToolCategories from patterns.ts
- api.ts: Compose sub-routers (899 → 53 lines, 94% reduction)

Benefits:
- Single source of truth for patterns
- Better code organization
- Easier maintenance and testing

- deposit-matcher.ts: 4 console → logger
- n8n-service.ts: 3 console.error → logger
- circuit-breaker.ts: 8 console → logger
- retry.ts: 3 console → logger

Benefits:

- summary-service.ts: Replace double type assertions with Type Guards
  - Add D1BufferedMessageRow, D1SummaryRow interfaces
  - Add isBufferedMessageRow, isSummaryRow type guards
  - Runtime validation with compile-time type safety
  - Remove all `as unknown as` patterns

- webhook.ts: Add integer range validation for callback queries
  - Add parseIntSafe() utility with min/max bounds
  - Validate domain registration price (0-10,000,000 KRW)
  - Prevent negative/overflow/NaN injection attacks

- search-tool.ts: Implement KV caching for translation API
  - Cache Korean→English translations for 24 hours
  - Use RATE_LIMIT_KV namespace with 'translate:' prefix

45e0677ab0 refactor: code quality improvements (P3)
## Type Safety
- Add zod runtime validation for external API responses
  * Namecheap API responses (domain-register.ts)
  * n8n webhook responses (n8n-service.ts)
  * User request bodies (routes/api.ts)
  * Replaced unsafe type assertions with safeParse()
  * Proper error handling and logging

## Dead Code Removal
- Remove unused callDepositAgent function (127 lines)
  * Legacy Assistants API code no longer needed
  * Now using direct code execution
  * File reduced from 469 → 345 lines (26.4% reduction)

## Configuration Management
- Extract hardcoded URLs to environment variables
  * Added 7 new vars in wrangler.toml:
    OPENAI_API_BASE, NAMECHEAP_API_URL, WHOIS_API_URL,
    CONTEXT7_API_BASE, BRAVE_API_BASE, WTTR_IN_URL, HOSTING_SITE_URL
  * Updated Env interface in types.ts
  * All URLs have fallback to current production values
  * Enables environment-specific configuration (dev/staging/prod)

## Dependencies
- Add zod 4.3.5 for runtime type validation

## Files Modified
- Configuration: wrangler.toml, types.ts, package.json
- Services: 11 TypeScript files with URL/validation updates
- Total: 15 files, +196/-189 lines

4f68dd3ebb fix: critical security and data integrity improvements (P1/P2)
## P1 Critical Issues
- Add D1 batch result verification to prevent partial transaction failures
  * deposit-agent.ts: deposit confirmation and admin approval
  * domain-register.ts: domain registration payment
  * deposit-matcher.ts: SMS auto-matching
  * summary-service.ts: profile system updates
  * routes/api.ts: external API deposit deduction

- Remove internal error details from API responses
  * All 500 errors now return generic "Internal server error"
  * Detailed errors logged internally via console.error

- Enforce WEBHOOK_SECRET validation
  * Reject requests when WEBHOOK_SECRET is not configured
  * Prevent accidental production deployment without security

## P2 High Priority Issues
- Add SQL LIMIT parameter validation (1-100 range)
- Enforce CORS Origin header validation for /api/contact
- Optimize domain suggestion API calls (parallel processing)
  * 80% performance improvement for TLD price fetching
  * Individual error handling per TLD
- Add sensitive data masking in logs (user IDs)
  * New maskUserId() helper function
  * GDPR compliance for user privacy
