We need to parse events and track beliefs about where each person thinks objects are located. The question: "Where does Wren believe the sturdy box is?" We need to infer based on actions observed by Wren? Usually these puzzles assume that people update their beliefs when they see an object being moved or placed somewhere; they know its current location after seeing it. If they didn't witness movement, they may not know.

We have initial statement: At 8:00, Oscar moved the sturdy box into the workshop. So at 8:00, Oscar moves sturdy box to workshop. Who sees this? It says Oscar moved... Not necessarily witnessed by others unless stated. Typically we assume only the actor knows the action; observers might not know unless they were present. But maybe we assume everyone knows what happened? However typical "belief tracking" tasks require noting who performed actions and who observed them. Since not specified, perhaps we assume that only the person performing the action knows the new location; others retain previous belief unless they later observe.

Thus we need to track Wren's belief about sturdy box.

Let's list timeline:

- 8:00: Oscar moved the sturdy box into the workshop.
   - Oscar now believes sturdy box is in workshop.
   - Others (Wren, Sofia) unknown/no change? They had prior belief? Initially unknown? Probably initially unknown location before any info. Could be unknown.

- 8:01: Wren carried the sturdy box to the gym.
   - Wren performs action moving sturdy box from wherever she thought it was to gym. She must have known its location before moving? To carry it, she must have known where it was. Did she know? She could have learned from earlier observation? At 8:00 Oscar moved it to workshop but Wren may not have seen that. Yet she carries it at 8:01, implying she knows where it is (maybe she saw Oscar move it? Or she found it?). In such puzzles, if a person moves an object, they must know its location at that moment (they are acting on it). So Wren's belief before moving: she believed it was somewhere (maybe workshop?) Actually she carried it to gym, so she must have taken it from its current location (where she believed it to be). After moving, she believes it's in gym.

Thus after 8:01, Wren believes sturdy box is in gym.

Now subsequent events involve blue tablet only, not sturdy box. No further mentions of sturdy box after 8:01. So Wren's belief about sturdy box remains as last known: gym, unless she later receives info that changes it (e.g., sees someone else moving it). No such events.

Thus answer: gym.

Check if any other actions could affect Wren's belief indirectly: At 8:02, she took the blue tablet and placed it in the workshop. That's about blue tablet, not sturdy box. No effect.

Thus Wren believes sturdy box is in gym.

Answer format: just location name: gym.
