health-check-endpoints

The multi-stack health-check implementations are broadly appropriate for Kubernetes health probes and monitoring, with typical patterns and separation of concerns across liveness, readiness, startup, and deep checks. Minor security and operational caveats exist (shell-based disk checks, exposure of config in payloads, placeholder external endpoints, and startup probe accuracy). With careful production hardening (configurable endpoints, sanitized outputs, platform-robust disk metrics), this pattern is solid for reliable health signaling.
