An unrecorded default-exposure flag means exposed
Default exposure carries the opposite polarity to the gate flags, deliberately. A port nobody has decided about is visible, so a parameter added after a node type was last saved does not silently vanish from the canvas.
The rule
Normative: this is the rule
- A port's default exposure defaults to true.
- Where a node type records no
exposedByDefaultvalue for a port, the port is exposed by default. - This polarity is the opposite of the gate flags (CFG-1) and is deliberate.
