情境
A newly-promoted engineering manager runs a Johari exercise with her team during a 1:1 retro. She populates the **Open** cell (things both she and the team see); the team adds to **Blind** (things they see that she doesn't); she fills **Hidden** privately; **Unknown** is the open hypothesis space — capabilities and limitations that haven't surfaced yet. The table form is the canonical Johari output. Coaches print it on a single page and walk through it with the coachee — a scatter plot of dots would defeat the entire purpose.
