Phases & Objections
Objection count, drain time, phase jump, sub-phases.
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
