 Generation ends when both lanes emit EOS. An unfinished lane at that ceiling
 is reported as `False` in `audio.eos`. Leading silence and pauses are retained;
 the shorter finished lane is zero-padded. CPU execution is available through

+**Verified from an anonymous public download** in a fresh Python 3.12 environment,
+using PyTorch 2.8.0+cu128 on one RTX PRO 6000 Blackwell. Both featured XML inputs
+generated valid 24 kHz stereo audio and both speakers emitted EOS. The 47.6-second
+and 54.4-second outputs took 50.7 and 57.4 seconds to generate, respectively,
+excluding about 28 seconds to load the model. Peak allocated CUDA memory was
+11.6 GB. The research repository was not installed. See [verification.json](verification.json).
