When and where this clue pays off

Two questions matter more than the pattern itself: does this clue give you everything now, or only later — and does it become a mark on the board, or a note you have to keep separately?

Builds as the board fills in

Nothing to mark on first read. This clue stays dormant until its trigger becomes true.

Needs a written note

Store it as a rule, not a mark. Write down the trigger and the consequence, and check it every pass.

Reading the clue is half the job. These are the methods that turn it into board progress.
