One date decides it: the end date of the deadline attached to your evaluation round. While that date is ahead, the competition sits under Open. The moment it passes, it moves to Closed. Nothing else is consulted, and no action of yours moves a card between the two tabs.
That is the same date the card prints as Due, with the days remaining beside it. Once it has gone by, the card reads Deadline passed and the competition is under Closed. The two always agree, because they are read from the same place.
It is the jury date, not the competition's
The date being tested belongs to your evaluation round, which is the jury window the organizer set for that panel. It is not the registration deadline, not the submission deadline, and not the results date, and it is usually well after all three. A competition can be long closed to entrants while your panel is still Open.
Closed does not mean you finished, and Open does not mean you have work left
Progress is a separate reading, shown as a chip on the card:
- Complete means you have scored every entry in that panel. A completed panel still sits under Open if its date has not passed.
- Closed on the chip means the date has passed, whether or not you scored everything. Scores you saved before it are kept, including partial ones.
- Urgent appears when three days or fewer remain.
So a card can say Complete under the Open tab, and a card under Closed can hold entries you never opened. Closed panels stay on the page permanently, with the button changed to View Analytics.
A tab you cannot see is a tab with nothing in it
Open, Closed and All are each drawn only when their own count is above zero. If every panel you sit on has finished, there is no Open tab at all. The practice competition is counted in none of the three and sits on its own above the grid.
