## Summary

DINOv3 features plus a vector database can achieve retraining-free operation in fixed-camera scenarios. Mechanistically, this works by changing the data rather than the model; in terms of cost, it shortens the cycle and carries no regression risk. The approach has clear boundaries of applicability: fixed viewpoint, a limited number of categories, stable lighting, and available operations and maintenance conditions.
