Model reasoning

We need to track beliefs. The question: "Where does Finn believe the shiny tablet is?" We need to infer Finn's belief based on his knowledge of events. We have a timeline of actions. Need to consider what Finn knows. Usually in belief tracking puzzles, each person only knows actions they observe or are involved in. We need to assume that each person only knows actions they performed or observed? The problem statement doesn't specify. Likely each person only knows actions they performed or directly observed (i.e., they see the object being moved when they are present). So we need to track Finn's knowledge of the shiny tablet location.

Timeline of shiny tablet moves:

8:00 Elliot carries shiny tablet to observation deck.
8:01 Elliot brings shiny tablet to south stairwell.
8:02 Maya brings shiny tablet to observation deck.
8:03 Tobias takes shiny tablet and places it in meditation room.
8:04 Finn takes shiny tablet and places it in print room.
8:05 Finn moves shiny tablet into greenhouse.
8:06 Juno takes shiny tablet and places it in east wing.
8:07 Maya takes shiny tablet and places it in storage room.
8:08 Juno carries shiny tablet to cafeteria.
8:09 Wyatt moves shiny tablet into print room.

After 8:09, no more shiny tablet moves. So final actual location is print room (by Wyatt at 8:09). But Finn's belief may be based on his knowledge up to his last observation.

Finn's involvement: At 8:04 he moved tablet to print room. At 8:05 he moved tablet into greenhouse. After that, Finn is not involved in tablet moves. So Finn's last action with tablet was moving it into greenhouse at 8:05. Did Finn see later moves? He might have observed later moves if he was present, but not indicated. So likely Finn believes it's still in greenhouse.

Thus answer: greenhouse.

Check if any later events could inform Finn: At 8:10 onward, actions involve dusty wrench, not tablet. So Finn hasn't observed further tablet moves. So his belief is greenhouse.

Thus answer: greenhouse.
