will v107 overfit for phase2?

Congratulations and thanks for your sharing.

i find v107 only use the about 5k query-ref pair (i.e. gt in phase1) as positive. How to know whether it overfits for phase2 ?

Actually, there is no way to assess overfitting, as ground-truth of phase-2 are not disclosed.
During the competition period, I compared several models by the copy detection result by eye-checking locally, and selected the model which shows most reasonable output.
