fn durable_identity(
worker_label: Option<&str>,
dynamic_labels: &[String],
) -> (Option<String>, bool)Expand description
(team_role, durable) for a caller’s worker label (None = the lead
or a plain catalog session). A lead is always durable and targets
itself. A worker is durable when its label holds a persisted row in
the session store, since that row is what brings it back.
