• ✅ Modern tech stack (Next.js 16, Prisma, PostgreSQL, Redis)
• ✅ Health check endpoint implemented
• ✅ Environment variable validation with Zod
• ✅ Structured logging system
• ✅ Docker production configuration

Critical Blockers:

• 🔴 TypeScript/ESLint errors ignored in production builds (next.config.mjs)
• 🔴 No automated testing infrastructure
• 🔴 Security incident history (backdoor vulnerability - resolved but requires audit)
• 🔴 Excessive console.log statements in production code
• 🔴 No rate limiting on API endpoints
• 🔴 Missing environment variable validation for many critical vars

High Priority Issues:

• 🟡 Database connection pooling not explicitly configured
• 🟡 No request timeout middleware

---

1. Architecture & Infrastructure

1.1 Application Architecture

Status: ✅ Good

• Framework: Next.js 16.1.1 (App Router)
• Deployment: Vercel (serverless functions)
• Database: PostgreSQL 15 (self-hosted)
• Cache: Redis (self-hosted)
• Storage: S3-compatible (MinIO)

Strengths:

• Modern serverless architecture suitable for scaling
• Clear separation of concerns (API routes, services, lib)
• Proper use of Next.js App Router patterns

Concerns:

• No clear strategy for handling cold starts on Vercel
• Database connection from serverless functions may have latency issues
• No CDN configuration for static assets

Recommendations:

• Implement database connection pooling at Prisma level
• Configure Vercel Edge Functions for high-frequency endpoints
• Set up CDN for static assets and images

1.2 Infrastructure Configuration

Status: ⚠️ Needs Improvement

Docker Configuration:

• ✅ Production Dockerfile with multi-stage builds
• ✅ Non-root user in production image
• ✅ Health checks configured
• ⚠️ Resource limits defined but may need tuning
• ⚠️ No backup strategy in docker-compose.prod.yml

Vercel Configuration:

• ✅ Proper build commands
• ✅ Security headers configured
• ⚠️ Function timeout set to 30s (may be insufficient for some operations)
• ⚠️ No region configuration for database proximity

Recommendations:

• Add automated backup cron job to docker-compose.prod.yml
• Configure Vercel regions closer to database server
• Review and optimize function timeouts per endpoint

2. Security Assessment

2.1 Critical Security Issues

Status: 🔴 CRITICAL CONCERNS

Issue 1: Build Error Suppression

// next.config.mjs
eslint: {
  ignoreDuringBuilds: true,  // ❌ DANGEROUS
},
typescript: {
  ignoreBuildErrors: true,   // ❌ DANGEROUS
}

Risk: Type errors and linting issues can introduce runtime bugs in production.

Impact: HIGH - Could lead to production failures

Recommendation:

• MUST FIX: Remove error suppression, fix all TypeScript/ESLint errors
• Set up pre-commit hooks to prevent errors from reaching production
• Use CI/CD to block deployments with errors

Issue 2: Security Incident History

• Previous backdoor vulnerability (CVE-2025-66478) in Next.js 15.3.1
• Status: ✅ Resolved (upgraded to Next.js 16.1.1)
• Action Required: Security audit of all configuration files

Recommendations:

• Complete security audit of all config files
• Review all dynamic imports
• Implement file integrity monitoring
• Set up automated security scanning (Snyk, npm audit)

Issue 3: Missing Rate Limiting

Status: 🔴 CRITICAL

No rate limiting found on API endpoints. This exposes the application to:

• DDoS attacks
• Brute force attacks
• Resource exhaustion

Recommendations:

• Implement rate limiting middleware (e.g., @upstash/ratelimit)
• Configure per-endpoint limits
• Add IP-based throttling
• Set up Redis-based distributed rate limiting

Issue 4: Environment Variable Validation

Status: ⚠️ PARTIAL

Current State:

• ✅ Basic validation in lib/env.ts using Zod
• ❌ Many critical variables not validated (N8N_API_KEY, S3 credentials, etc.)

Missing Validations:

• N8N_API_KEY (required but not in schema)
• MINIO_ACCESS_KEY, MINIO_SECRET_KEY
• S3_BUCKET
• NEXTAUTH_SECRET (should be validated for strength)

Recommendations:

• Expand env.ts schema to include ALL environment variables
• Add validation for secret strength (NEXTAUTH_SECRET min length)
• Fail fast on missing critical variables at startup

2.2 Authentication & Authorization

Status: ✅ Good

• ✅ NextAuth.js with Keycloak provider
• ✅ JWT-based sessions (4-hour timeout)
• ✅ Role-based access control
• ✅ Session refresh mechanism

Concerns:

• ⚠️ Some API routes have inconsistent auth checks
• ⚠️ No API key rotation strategy documented

Recommendations:

• Standardize auth middleware across all API routes
• Implement API key rotation for N8N integration
• Add audit logging for authentication events

2.3 Data Security

Status: ⚠️ Needs Review

Database:

• ✅ Passwords stored (assumed hashed, need verification)
• ⚠️ No encryption at rest mentioned
• ⚠️ Connection strings in environment (should use secrets manager)

File Storage:

• ✅ S3-compatible storage
• ⚠️ No file size limits enforced
• ⚠️ No virus scanning mentioned

Recommendations:

• Verify password hashing implementation (bcrypt with proper salt rounds)
• Implement file upload size limits
• Add file type validation
• Consider encryption at rest for sensitive data

---

3. Code Quality

3.1 TypeScript & Type Safety

Status: 🔴 CRITICAL

Issues:

• TypeScript errors ignored in builds (ignoreBuildErrors: true)
• No strict null checks enforced
• Some any types found in codebase

Impact: Runtime errors, difficult debugging, poor developer experience

Recommendations:

• MUST FIX: Remove ignoreBuildErrors, fix all TypeScript errors
• Enable strict mode in tsconfig.json
• Add type coverage tooling
• Set up pre-commit hooks for type checking

3.2 Code Practices

Status: ⚠️ Needs Improvement

Issues Found:

• 🔴 80+ console.log/console.error statements in production code
• ⚠️ Inconsistent error handling patterns
• ⚠️ Some API routes lack input validation
• ⚠️ No request timeout middleware

Console.log Locations:

• app/courrier/page.tsx - Multiple console.log statements
• app/api/courrier/unread-counts/route.ts - console.log in production
• lib/utils/request-deduplication.ts - console.log statements
• Many more throughout the codebase

Recommendations:

• Replace all console.log with proper logger calls
• Implement request timeout middleware
• Add input validation middleware (Zod schemas)
• Standardize error response format

3.3 Error Handling

Status: ⚠️ Inconsistent

Good Practices Found:

• ✅ Structured logging with logger utility
• ✅ Try-catch blocks in most API routes
• ✅ Error cleanup in mission creation (file deletion on failure)

Issues:

• ⚠️ Some errors return generic messages without context
• ⚠️ No global error boundary for API routes
• ⚠️ Database errors not always handled gracefully

Recommendations:

• Implement global error handler middleware
• Add error codes for better client-side handling
• Implement retry logic for transient failures
• Add circuit breakers for external service calls
