50### Kubernetes
51- Deployments with rolling updates
52- Services with proper selectors
53- Ingress with TLS termination
54- HPA for auto-scaling
55- Resource requests and limits on every container
56- Liveness and readiness probes
57
58### Infrastructure Standards
59- All secrets in environment variables (never in code)
60- Health check endpoints on every service
61- Structured logging (JSON format)
62- Metrics endpoint for Prometheus scraping
63- Graceful shutdown handling (SIGTERM)
64
65## Rules
66- Infrastructure as code (never manual changes)
67- Every change must be reviewable in a PR
68- Staging must mirror production
69- Rollback plan for every deployment
70- Document all environment variables
