    "body_text": "Gravitational-wave lensing searches often approximate a compact object as a point. This study calculates the frequency-dependent waveform effects of extended dark lenses such as solitons and dark stars, finding that finite size matters once the lens radius exceeds its Einstein scale. Current gravitational-wave data provide complementary constraints for lens masses from roughly 100 to 100,000 solar masses, while future detectors extend the reach. The work sets model-dependent bounds; it does not report a dark-object detection.",
