Enum ToWorker 

pub enum ToWorker {
    Barrier(u64),
    Commit(u64),
    Stop,
}

Runtime control from the leader to a worker over the persistent control connection (D9 — the leader coordinates the run; barriers travel in-band on the data edges, but the decision to issue an epoch, commit it, or stop is the leader’s). Barrier(e) injects epoch e at this worker’s sources (aligned across all workers, so an operator sees the same epoch on every edge); Commit(e) releases the sources that recorded a position at e; Stop begins the ordered shutdown.

Variants
