Subhalos produce percent-level modulations in saddle and minimum images; matched-filter analysis yields >5σ combined detections in 62% of realizations for fiducial sources near caustics, projecting 10-20 substructure detections over the LISA mission.
Combining multiple lensed images of the same gravitational-wave event improves sky localization by up to an order of magnitude, reaching 10-100 deg² for four-image systems.
