Phase 8 — Production Systems

Chapters 53, 54: Harden & Secure

Your role: Shipping Engineer — "I can harden, secure, and ship production-grade software"

Working code and production code are not the same thing. Phase 8 bridges that gap. You build a GitHub Actions CI pipeline that automatically runs your full verification stack on every commit, and you learn to audit AI-generated code for the security vulnerabilities that AI consistently misses — because AI optimizes for functionality, not security. You become the human firewall.
