Assert the study strip by its own sentence, not the study name

The source picker's option label carries the study title on snapshots
that use it as the composite display name, so name-containment both
false-failed the merged no-strip check and vacuously passed the pinned
strip check. The strip's budget sentence appears nowhere else.
