Security: - Drop ALL capabilities, enforce non-root, RuntimeDefault seccomp on neuron-mcp, neuron-rest, neuron-marketing pods - Add startup probes (150s window for JVM) so liveness doesn't fire early - Replace docker-sock hostPath with BuildKit rootless TCP endpoint (moby/buildkit:v0.19.0-rootless) — removes node root access from CI - Document full ESO AppRole migration path in cluster-secret-store.yaml Autoscaling & availability: - HPAs on mcp (1–6), rest (1–4), marketing (2–8) at 65–70% CPU - PodDisruptionBudgets (minAvailable: 1) on all three services - NetworkPolicy: default-deny-all in neuron-prod, explicit allow rules for Traefik ingress, intra-namespace, and egress to DNS/platform/vault Observability: - ServiceMonitors for mcp, rest, marketing (cross-namespace enabled in kube-prometheus-stack with serviceMonitorSelectorNilUsesHelmValues:false) - PrometheusRules: high error rate, high latency, crash loops, replica shortage, Postgres down/connections, backup failure, backup staleness Chart version pinning: - kube-prometheus-stack, loki, tempo, redis, alloy, postgres — all pinned to major-version ranges to block silent breaking upgrades Backup hardening: - restic:latest → restic:0.17.3 (deterministic image) - Weekly backup-verify CronJob: restores latest snapshot and validates SQL dump structure (≥5 CREATE TABLE, pg_dump header check) ArgoCD: - neuron-prod AppProject: scopes deploys to neuron-prod + platform ns, blacklists ClusterRole/ClusterRoleBinding/Namespace creation, automated sync window 2–6am UTC, manual always allowed

# PodDisruptionBudgets for neuron-prod
|
|
# Ensures at least 1 replica of each service survives node drains and upgrades.
|
|
# With replicas=1 today, minAvailable=1 means drain will block until HPA scales up
|
|
# to 2+ — this is intentional and provides a natural safety gate.
