Day 8 Instructor-Led Video — Main Ball Plus Bonus

Core Claim

Main balls and bonus balls are separate ontology objects with separate semantics.

Why It Matters

This is a Lotto-style boundary test. Main balls and bonus balls are separate ontology objects with separate semantics. The lesson keeps set objects and bonus objects separate. That keeps Pick-style assumptions from slipping into the answer.

Practical Takeaway

Before answering any family-spanning question, write one line that states matrix type, object type, and primary metric.

Common Misread

Assuming the bonus ball behaves like the main balls.
