Chapter: testability
Rule: driftId
Spec: Drifted locator
The control is still there but its name or locator moved. Old tapes and specs click the wrong widget or none.
Inspect marked the widget as drifted. Not this: zero matches (T-10); two widgets share one locator (T-12).
This id is stable. Reports link here so T/V/Q classes do not shuffle when a soak ranks differently.
