fn orphaned_subscriptions(
registered: &[String],
is_live: impl Fn(&str) -> bool,
) -> Vec<String>Expand description
Subscribed agents no live block holds. Every way into the subscription
(add_agent) runs with a live registration, so one without is a leak
from a teardown that missed it; renewing its WAN lease would fence the
agent everywhere else for as long as this srv runs.
