Reusable Workflow script that audits whether the cluster is memory-overcommitted and whether a single k8s worker can be removed to return RAM to the PVE host without sacrificing N-1 failover. Read-only throughout: gathers PVE host memory (qm config / free / KSM via SSH), k8s per-node capacity + cluster 30d peak working set, and per-workload right-sizing, then models N-1 two ways (physical actual-usage and scheduling-by-request) and adversarially verifies the conclusion with 3 skeptics.
Sizes requests (scheduling reservation) and limits (OOM ceiling) as SEPARATE knobs — an earlier ad-hoc pass conflated them by sizing requests to 30d peak, which manufactured a false N-1 shortfall. Invoke via Workflow {scriptPath}, or by name when cwd is the infra repo.
Requested by Viktor: identify memory overcommit and whether deployment requests can be trimmed to free PVE host RAM by removing a node, without sacrificing service reliability.
