  "method": "The two-page PDF was genuinely read. Independent comparison with the source found eight RH pitches in bar7 a diatonic third too low. They were corrected in the product before the practice link was created. All467 source-note events otherwise match.",
  "musical_checks": "The music is not simplified. The practice example changes tempo, hand selection and a loop. Its link is a snapshot of corrected version2. The source\u2019s final arpeggio sign is omitted in playable notation; final fermatas remain. Ornamental playback is the app\u2019s interpretation.",
