    "answer": "TH1 places A's blue-square event at video second 6. TH2's verified two-second offset maps audio second 4 to that instant, aligning the original Harbor line. A separately retained reference key can check the event's cue label after the model responds, but must not be included as input. TH3 changes B's event timing without supplying B's audio alignment, so A's offset cannot establish B's corresponding dialogue instant.",
