ReadonlyhostReadonlylaneOptional ReadonlysignalOptional ReadonlytrackingPresent on tracked nodes' run only; remove gets the GlobalId as its argument instead.
OptionalmarkReports that this invocation's result depends on the world outside the
graph (it made a network request), so the node's outputs from this run
are not memoised: the next run computes them again. The per-run form of
NodeDef.volatile, for a node that only sometimes reaches out (a script
that may or may not call bim.network.fetch). Optional so a context
built outside the scheduler (a unit test) need not supply it.
The lane this invocation computes, or
nullwhen the node was not lifted.
