NK-WP-0052 — Wave-2 resource right-sizing from the 2026-10-21 allocation review

Receiving workplan in net-kingdom for the wave-2 request changes below. Login path for the whole fleet; apply one Deployment at a time and test sign-in after each.

Origin: the 2026-10-21 node allocation review (RESOURCE-WP-0008-T03, feeding CUST-WP-0071-T03). Per the founder's 2026-10-21 delivery interview (the-custodian/docs/decisions/2026-10-21-cust-wp-0071-delivery-interview.md) the small adjustments form wave 2: one receiving task per owner repo, applied later in a batch. Applying wave 2 needs a separate founder approval, so every cluster-write task here is a human-gated wait. This file changes no manifest.

Values are pod-aggregate figures from the budget file (7-day window ending 2026-10-21T06:08Z). Limits stay unchanged unless stated.

Workload (ns/name) Pods CPU request CPU limit CPU p95/peak 7d (m) Memory request Memory limit Mem p95/peak (Mi) Throttle Action
mfa/net-kingdom-sso-mfa 1 110m → 20m 1000m 12.2/23.1 384Mi → 272Mi 896Mi 225.6/225.8 0.049 decrease + memory down
sso/net-kingdom-sso-mfa 4 150m → 40m 1150m 22.4/34.5 256Mi → 176Mi 640Mi 140.5/179.1 0.537 decrease + review CPU limit (throttled) + memory down

Source and container detail:

  • mfa/net-kingdom-sso-mfa: namespace mfa: Deployment privacyidea, container privacyidea (sso-mfa/k8s/privacyidea/deployment.yaml, 100m/256Mi) plus the remaining 10m/128Mi in the same pod (confirm which container) — split the 20m/272Mi proposal across them. Also ~5% throttling at the 500m container limit.
  • sso/net-kingdom-sso-mfa: namespace sso, four Deployments: keycape (25m/32Mi, limit 200m, sso-mfa/k8s/keycape/deployment.yaml), lldap (50m/64Mi, limit 200m), authelia (50m/128Mi, limit 500m), identity-provisioner (25m/32Mi, limit 250m). 53.7% of CFS periods throttled on the login path: find the throttled container(s) and review their CPU limit independently of the request decrease.

Evidence: resource-control docs/evidence/2026-10-21-node-allocation-review/2026-10-21-node-budget.md (+ .json, commit 3d9b1bd). Rule: CPU = max(floor, p95x1.5, peakx0.5) rounded up to 5m; memory request = 7d p95 working set x1.15 (only when the change is at least 64Mi).

Steps:

  1. Map the pod-aggregate proposal onto the named container(s) in the source file; where a workload has several containers or pods, split by the per-pod figures in 2026-10-21-workload-usage.json and keep the sum at the proposed value.
  2. Prepare the source change as a reviewed commit (no push, no sync) and record the before values here.
  3. Apply only inside the batched wave-2 rollout, after founder approval, through the owner's normal deploy path (ArgoCD sync or documented helm/kubectl apply).

Verification: kubectl -n <ns> get pod -o jsonpath='{..resources}' shows the new requests; pods Ready with no new restarts or OOMKilled over 24h; for CPU decreases the throttle ratio and request latency stay at or below the 7d baseline; node request total drops by the expected delta.

Rollback: revert the source commit and re-sync/re-apply; the before values in the table above are the rollback target. Keep before/after kubectl get -o yaml captures as the receipt.
