 2. Duplicates: delete the weaker/less specific version and keep the clearer one.
 3. If duplicate, set duplicate_of_id to the kept question's id.
 4. Do NOT delete for minor wording issues or intensity mismatches.
+5. IMPORTANT: Asymmetric versions of the same activity are NOT duplicates. If one question has text="Do X to your partner" and another has text="Let your partner do X to you", these are DIFFERENT questions because they have different initiators. Only flag as duplicate if both questions have the SAME initiator doing the SAME action.
