WHITEBOARD CHAIN

1. DECLARE    interfaces / types / ports you need
2. SKELETON   class extends + utils macro + key methods
3. MECHANISM  fill one critical method while narrating
4. PITFALL    name one bug juniors make on this pattern
5. TEST       how you would smoke-test the component

Stimulus → predictor → exp analysis → scoreboard. Monitor → act analysis → scoreboard.

Key takeaways

Predictor transforms; scoreboard only compares.
