Week 16 Review
| Day | Skill | Real-World Use |
|---|---|---|
| 113 | End-to-end attack simulation | Verify the integrated stack actually defends |
| 114 | Per-middleware latency profiling + optimization | Establish SLA: "WAF adds 300µs p99" |
| 115 | Security self-audit (timing, overflow, info leak, goroutine exit) | Pre-launch adversarial review |
| 116 | Test coverage audit (≥80% on security packages) | Compliance evidence and confidence |
| 117 | Fuzz testing (WAF normalization, schema validator, protocol parser) | Find panic paths before attackers do |
| 118 | Architecture documentation + ADRs + operational runbook | Knowledge transfer and team enablement |
| 119 | Pre-capstone integration + all quality gates | Day 120 is assembly, not discovery |
Engineer Takeaway
This week is what "engineering excellence" looks like in practice: attack simulation, profiling, self-audit, coverage, fuzzing, and documentation — all before shipping. Teams that skip this week ship faster but pay the cost in incidents. Teams that do this week ship slightly slower but run reliably for years.
