  "case_id": "CASE-D09B",
  "identification": {
    "recognition_level": "specific_candidate",
    "composer": "Wolfgang Amadeus Mozart",
    "work": "Piano Sonata in D major, K. 576",

    "evidence_ids": ["E001", "E002", "E003", "E004", "E016", "E017", "E018"],
    "reason": "The 6/8 D-major octave opening, distinctive D-A-D-F-sharp-D-F-sharp figure, trill-led continuation, and exact thematic return at E016 strongly identify the first movement of Mozart's K. 576."

## Limitations

Identification is based solely on symbolic pitch, rhythm, texture, ornament, and recurrence evidence. No score, audio, attribution metadata, external reference, or catalogue lookup was used. Sonata numbering varies by edition, so the catalogue identifier K. 576 is more reliable than a numbered title.
