+# 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.
+
+## Apply the reviewed request changes
+
+```task
+id: NK-WP-0052-T01
+status: wait
+priority: medium
+needs_human: true
+blocking_reason: "Wave-2 cluster write; founder approval for wave 2 not yet given (2026-10-21 interview)"
+```
+
+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.
