  "method": "The complete two-page PDF was genuinely read. All425 right-hand and295 left-hand source notes matched the edition\u2019s MIDI in pitch, onset and duration. A web AI request created a closer-position accompaniment on a copy.",
  "musical_checks": "Every RH event is unchanged. The left-hand rhythm and the complete two-hand harmonic pitch-class sets are preserved. The largest consecutive movement of the lowest LH note falls24\u21929semitones; in bar2 bass-to-next-chord lowest note falls19\u21924. These measure register travel, not hand span. Some octave chords remain.",
  "settings": "Both use a chosen90quarter-notes/minute practice setting; this is not a tempo attributed to the source.",
