We need to parse the narrative. Elliot is the person who at 8:00 took the blue tablet and placed it in the workshop. Then later events: At 8:01, he brought the blue tablet over to the loading dock. So Elliot moved it to loading dock at 8:01. At 8:02, Hana took the blue tablet and placed it in the storage room. At 8:02, he (Elliot) happened to be watching. So Elliot observed Hana moving it to storage room at 8:02. So Elliot knows it's now in storage room at that moment.

At 8:03, Sofia carried the blue tablet to the basement. At 8:03, he noticed this from across the room. So Elliot sees Sofia moving it to basement at 8:03. So Elliot now believes it's in basement.

At 8:04, he (Elliot) brought the blue tablet over to the archive room. So Elliot moves it from basement to archive room at 8:04. So Elliot now believes it's in archive room.

At 8:05, Sofia carried the blue tablet to the garage. At 8:05, he noticed this from across the room. So Elliot sees Sofia moving it to garage at 8:05. So Elliot now believes it's in garage.

At 8:06, she moved the blue tablet into the north stairwell. At 8:06, he noticed this from across the room. So Elliot sees it moved to north stairwell at 8:06. So Elliot now believes it's in north stairwell.

At 8:07, she moved the blue tablet into the loading dock. At 8:07, he was nearby and saw this happen. So Elliot sees it moved to loading dock at 8:07. So Elliot now believes it's in loading dock.

At 8:08, Hana moved the blue tablet into the basement. At 8:08, he happened to be watching. So Elliot sees it moved to basement at 8:08. So Elliot now believes it's in basement.

At 8:09, she (Hana?) carried the blue tablet to the mail room. No mention of Elliot seeing? It says "she carried the blue tablet to the mail room." No note about Elliot noticing. So Elliot may not have observed this move. So his belief remains that it's in basement (last observed location) unless he later sees further moves.

At 8:10, Sofia moved the blue box into the basement. Note: "blue box" not tablet. Might be different object. So ignore for tablet.

At 8:11, she carried the blue box to the mail room. Also box.

At 8:12, she reorganized some papers on the desk. No tablet.

At 8:13, Elliot refilled a cup of coffee. No tablet.

At 8:14, he checked their email. No tablet.

Thus Elliot's last observation of the tablet was at 8:08 when Hana moved it to the basement. He didn't see the 8:09 move to mail room. So Elliot believes the tablet is in the basement.

Thus answer: basement.
