Northern Trail Outfitters injects outcomes into Journey B based upon email engagement in Journey A.

The best method is:

Use an Engagement Split in Journey A to identify engagement.

Use Update Contact Activity to update a Boolean field in a Data Extension based on the engagement result.

Later, query this updated engagement Data Extension to inject subscribers into Journey B based on their behavior.

This avoids relying directly on querying system data views and enables near-real-time, easy-to-manage segmentation.
