  "transformations": [
    "First 64 quarter-note beats per edition; nearest-sixteenth attack quantization; discard duration, pedal, dynamics, tempo changes and percussion.",
    "Transpose Easy Winners +4 semitones (A-flat to C); leave Entertainer unchanged.",
    "Split at MIDI pitches 60 and 72. Keep lowest bass, up to three lowest chord tones, highest melody. Constant per-voice velocity.",
    "The Pascal learner appends two opening frames to each excerpt before open-boundary learning. This end-to-start transition is an authored loop assumption, not evidence from the original score.",
    "WFC learns order-2 ensemble and rhythm, order-1 harmony models. The runtime generates constrained sections, not a shuffled playlist."
  ],
  "limitations": "Statistical recombination can reproduce recognizable phrases and repeat. No guarantee of novelty, stylistic fidelity, or musical quality."
