Struct Cut 

pub struct Cut {
    pub to: SigId,
    pub from: SigId,
    pub carries: Ty,
    pub id: String,
}

A dataflow edge whose two ends are on different tiers.

§4.3: “Every signal edge that crosses tiers becomes a subscription: the server side gets a diff operator, the client side a resumable (subscription, seq) consumer.” Phase 1 and Phase 2 knew about exactly one crossing and printed a sentence about it; this enumerates them, and gives each the content-derived id a resumable subscription is keyed by.

Fields

to: SigId

The consumer — the downstream end, which subscribes.

from: SigId

The producer — the upstream end, which diffs and streams.

carries: Ty

id: String

blake3(module, producer, consumer, structural(carried))[..16], by the same rule as the command channel’s operation id: content, not names a human maintains.
