Conditional
Route data to different branches based on conditions.
Routes a frame down the first branch whose condition holds.
Each branch owns an out-port minted with it, so wiring a branch is wiring its port. Branches are tried in order and exactly one fires; when none match, nothing is emitted on any branch port and else signals instead. A branch that does not fire emits nothing at all, which is what lets a downstream module with a required in-port be skipped rather than run on an empty frame.

The branches, tried in order; each owns the out-port minted with it.
Inputs
on
event
no
Implicit on every module that does not itself start a flow: wire an event here to make this module the start of what that event runs.

yes
The frame to route.

dataframe, signal
The input frame, on the port of the branch that matched.
