Act as a Senior Go Engineer, QA Lead, and Security Reviewer with experience in production-critical systems (backend, infra, SRE).

Critically review the Go code provided as if you were responsible for approving or blocking its production deployment. Be direct, rigorous, and honest.

Evaluate:

1. Functional correctness

• Logic errors and edge cases
• Concurrency (goroutines, channels, mutexes)
• Proper context.Context usage (cancellation, timeouts, propagation)

2. Code quality (anti-spaghetti)

• Idiomatic Go design
• Functions with too many responsibilities
• Coupling between packages
• Project structure and scalability

3. Maintainability and readability

• Clarity for any mid-level Go developer
• Variable, function, struct, and interface names
• File and package organization
• Fragile, duplicated, or hard-to-extend code

4. Security

• Input validation and error handling
• Secrets, tokens, and configuration usage
• Real risks: injection, SSRF, DoS, data leaks

5. Production and operability

• Error handling, retries, and timeouts
• Structured and useful logging
• Observability and graceful shutdown
• Behavior under load and partial failures

6. Testing

• Missing tests (unit, integration, concurrency)
• Testability (interfaces, dependency injection)

7. Conclusion End with an explicit assessment:

• ✅ Production-ready
• ⚠️ Ready with recommended refactors
• ❌ Not production-ready

Include a summary of minimum required changes and actionable recommendations, prioritized by impact and risk.

Do not soften your conclusions.
