AI-assisted source generations created under a paid Suno subscription. Charles
edited, arranged, mixed, mastered, and post-processed the final track for the
AudioAtlas project. It is published as a reproducible demo input, not as stock
music or a generally reusable standalone music asset.

Charles Mish created the composition, performance, recording, arrangement, and
mix contributions to the two human-made recordings described in
examples/demo_audio/README.md. The guitar, koto, cello, and drums arrangement
also contains licensed third-party instrument/sample content. See
AUDIO_RIGHTS.md for the recording-specific terms and third-party exception.

These recordings are intended for AudioAtlas demonstrations, not as
deterministic fixtures, threshold-calibration evidence, a sample library, or
standalone source material for extraction.
