Mobile

A second entry point sharing the first one's contracts.

Native experience3 industries require it3 published systems

Argument

Mobile is not a smaller web page. It is a parallel node in the same experience layer, which only works when the platform contracts beneath both are explicit.

Role in the system

Parallel, not derivative.

Mobile occupies the same experience layer as web and reaches the same API platform. Neither is upstream of the other, and neither owns state the other cannot see.

This is where implicit contracts fail. Two entry points against an under-specified platform diverge quietly, and the divergence surfaces as inconsistency the visitor experiences as a bug.

System effect

One more node in the same layer.

The composition below places mobile beside web rather than beneath it. The layers either side are unchanged — which is exactly what makes a second entry point affordable.
