"""Shared client-journey contract and result lifecycle helpers.
The mobile/browser driver still owns the real UI interaction. This module
owns the parts that must be identical for every client catalog: contract
validation, preflight blocking, and result propagation. It deliberately
returns the existing tester result vocabulary instead of introducing a second
report format.
