Wave-2 apply is human-gated; no manifest changes.

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: TREV-WP-0016-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).

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 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.
