Section goal

Phase and objection questions are the #1 hang-debug interview topic. Practice timelines on paper, not just code.

Mechanism to narrate

• Objection count > 0 prevents simulation end

• Every raise needs a matching drop (test, seq, or component)

• drain_time lets DUT pipeline flush after drop
