/**
 * Domain-affinity routing policy — ADR-164 §3.4.
 *
 * Surfaces a deterministic routing decision for `@metaharness/router` to use
 * before its KRR cost-optimal step. The policy is intentionally tiny —
 * three branches over `preferLocalExecution` and `budgetUsdMonthly` — so the
 * decision is auditable from the pod template alone, no learned-weight side
 * effects.
 *
 * Rules (per the Phase-3 brief):
 *   1. `preferLocalExecution === true`                                  → 'local-stdio'
 *   2. `preferLocalExecution === false` AND `budgetUsdMonthly >= 50`    → 'cloud-managed'
 *   3. otherwise                                                        → 'remote-peer'
 *
 * The boundary `>= 50` matches the Phase-2 sales template (budget 50/month) —
 * it routes the canonical reference pod to the cloud-managed backend. Pods
 * below the threshold default to the federation peer-node backend.
 *
 * Wire point: `@metaharness/router` reads the result and supplies it as a
 * routing hint *before* its KRR step. The router is free to override on
 * latency/cost grounds — domain affinity is a policy floor, not a hard gate.
 *
