// Unit coverage for the capability-barrier bounded-wait duration policy (#289). The value is baked
// into every plan-fanout instance's `capsWaitTimeout` process variable and evaluated by the
// `wait-caps-timeout` timer arm on the `wait-caps-resolved` event-based gateway, so a malformed
// operator env must never deploy an uninterpretable `<bpmn:timeDuration>` — it falls back to the
// default instead. Run with `node --test`.
