BeatScope measures a song — beats, transients with band energies, tempo changes, bars, cues, structure — and exports a portable timing package: deterministic runtime, self-check probe, hash-verified files. No audio, no visual style, no task statement, so the picture stays the consumer's decision. Beathi, the same app, turns those measurements into a music video on your machine. Same seed, same film, every time. Windows build, pip wheel, MIT.
