Verified against railiance01 on 2026-08-12 once API access was restored.
Corrections: two clusters are managed, not one - railiance01 is the current
primary running the live workloads, CoulombCore is the older frozen cluster.
Traefik is the ingress controller, not nginx. ArgoCD is not on railiance01 at
all; it runs on CoulombCore only, so the previous entry was accurate for that
host but misleading as a general cluster-level claim.
Adds the verified addon and CNPG cluster inventory, notes the absence of any
monitoring stack, and points at RAIL-HO-WP-0009 for the source-restricted k3s
API.
