The room has forty minutes to fix an ending nobody likes, and every option on the table makes somebody's least favorite character right.
Dana pitches the ending nobody asked for — and by the cold open of episode two, it's the only one anyone remembers pitching.
The implicit grid explanation finally made this click for me. I had been declaring rows for years without knowing why it sometimes worked anyway.
That is exactly the trap — it works right up until the content count changes. Glad it helped.
Would love a follow-up on subgrid. It is the one part I still avoid.
