Co-op case files
Neither investigator sees the whole evidence file. Compare what you know through the partner channel and make one shared deduction.
File A / File B
Deduction as a conversation.
Each partner receives a deterministic half of the evidence. Your timeline may be complete while your partner holds the access records. Nobody can solve alone, so the collaboration is the puzzle — and the solution stays server-side until the room submits one shared deduction.
